The minimal important difference of patient-reported outcome measures related to female urinary incontinence: a systematic review.

BACKGROUND: The minimal important difference is a valuable metric in ascertaining the clinical relevance of a treatment, offering valuable guidance in patient management. There is a lack of available evidence concerning this metric in the context of outcomes related to female urinary incontinence, which might negatively impact clinical decision-making. OBJECTIVES: To summarize the minimal important difference of patient-reported outcome measures associated with urinary incontinence, calculated according to both distribution- and anchor-based methods. METHODS: This is a systematic review conducted according to the PRISMA guidelines. The search strategy including the main terms for urinary incontinence and minimal important difference were used in five different databases (Medline, Embase, CINAHL, Web of Science, and Scopus) in 09 June 2021 and were updated in January 09, 2024 with no limits for date, language or publication status. Studies that provided minimal important difference (distribution- or anchor-based methods) for patient-reported outcome measures related to female urinary incontinence outcomes were included. The study selection and data extraction were performed independently by two different researchers. Only studies that reported the minimal important difference according to anchor-based methods were assessed by credibility and certainty of the evidence. When possible, absolute minimal important differences were calculated for each study separately according to the mean change of the group of participants that slightly improved. RESULTS: Twelve studies were included. Thirteen questionnaires with their respective minimal important differences reported according to distribution (effect size, standard error of measurement, standardized response mean) and anchor-based methods were found. Most of the measures for anchor methods did not consider the smallest difference identified by the participants to calculate the minimal important difference. All reports related to anchor-based methods presented low credibility and very low certainty of the evidence. We pooled 20 different estimates of minimal important differences using data from primary studies, considering different anchors and questionnaires. CONCLUSIONS: There is a high variability around the minimal important difference related to patient-reported outcome measures for urinary incontinence outcomes according to the method of analysis, questionnaires, and anchors used, however, the credibility and certainty of the evidence to support these is still limited.

Facial recognition, laterality judgement, alexithymia and resulting central nervous system adaptations in chronic primary headache and facial pain-A systematic review and meta-analysis.

INTRODUCTION: Patients with chronic headaches and chronic oro-facial pain commonly present psychosocial issues that can affect social interactions. A possible reason could be that patients with these disorders might present impairments in facial recognition, laterality judgement and also alexithymia. However, a systematic review summarizing the effects of facial emotion recognition, laterality judgement and alexithymia in individuals with headaches and oro-facial pain is still not available. AIM: The main objective of this systematic review (SR) and meta-analysis (MA) was to compile and synthesize the evidence on the occurrence of alexithymia, deficits in laterality or left-right (LR) recognition and/or facial emotion recognition (FER) in patients with chronic headache and facial pain. METHODS: Electronic searches were conducted in five databases (up to September 2023) and a manual search to identify relevant studies. The outcomes of interest were alexithymia scores, speed and accuracy in LR and/or FER, or any other quantitative data assessing body image distortions. The screening process, data extraction, risk of bias and data analysis were performed by two independent assessors following standards for systematic reviews. RESULTS: From 1395 manuscripts found, only 34 studies met the criteria. The overall quality/certainty of the evidence was very low. Although the results should be interpreted carefully, individuals with chronic headaches showed significantly higher levels of alexithymia when compared to healthy individuals. No conclusive results were found for the other variables of interest. CONCLUSION: Although the overall evidence from this review is very low, people with chronic primary headaches and oro-facial pain could be regularly screened for alexithymia to guarantee appropriate management.

Effectiveness of electrotherapy for the treatment of orofacial pain: A systematic review and meta-analysis.

OBJECTIVE: Summarize the evidence from randomized controlled trials and controlled trials that examined the effectiveness of electrotherapy in the treatment of patients with orofacial pain. DATA SOURCE: Medline, Embase, CINAHL PLUS with Full text, Cochrane Library Trials, Web of Science, and Scopus. REVIEW METHODS: A data search (last update, July 1, 2022) and a manual search were performed (October 5, 2022). Trials involving adults with orofacial pain receiving electrotherapy compared with any other type of treatment were included. The main outcome was pain intensity; secondary outcomes were mouth opening and tenderness. The reporting was based on the new PRISMA Guidelines. RESULTS: From the electronics databases and manual search 43 studies were included. Although this study was open to including any type of orofacial pain, only studies that investigated temporomandibular disorders were found. The overall quality of the evidence for pain intensity was very low. Although the results should be carefully used, transcutaneous electric nerve stimulation therapy showed to be clinically superior to placebo for reducing pain after treatment (2.63 [-0.48; 5.74]) and at follow-up (0.96 [-0.02; 1.95]) and reduce tenderness after treatment (1.99 [-0.33; 4.32]) and at follow-up (2.43 [-0.24; 5.10]) in subjects with mixed temporomandibular disorders. CONCLUSION: The results of this systematic review support the use of transcutaneous electric nerve stimulation therapy for patients with mixed temporomandibular disorders to improve pain intensity, and tenderness demonstrating that transcutaneous electric nerve stimulation is superior to placebo. There is inconsistent evidence supporting the superiority of transcutaneous electric nerve stimulation against other therapies.

Kinematic analysis of sensorimotor control during the craniocervical flexion movement in patients with neck pain and asymptomatic individuals: a cross-sectional study.

BACKGROUND: Patients with craniocervical pain have shown reduced performance in the craniocervical flexion test (CCFT). However, there is limited evidence of other possible kinematic alterations not assessed in the context of the CCFT. Previous studies on other functional or planar movements have reported alterations in sensorimotor control (e.g., range of motion [ROM], velocity, or smoothness) in subjects with neck pain. The objective of this study was to explore the association between sensorimotor control variables associated with craniocervical flexion movement and different characteristics related to pain, age, disability, and fear of movement in individuals with non-traumatic chronic neck pain and asymptomatic controls. METHODS: This was an observational, cross-sectional study in patients with non-traumatic neck pain and asymptomatic participants. Regression models were used to assess whether descriptive characteristics of the sample, including: (a) age, (b) intensity of pain, (c) neck disability, (d) chronicity of pain, and (e) fear of movement could explain sensorimotor control variables such as ROM, velocity, jerk, head repositioning accuracy, and conjunct motion. All these variables were recorded by means of light inertial measurement unit sensors during the performance of three maximal repetitions of full range craniocervical flexion in the supine position. RESULTS: A total of 211 individuals were screened and 192 participants finished the protocol and were included in the analyses. Participants had an average age of 34.55 ± 13.93 years and included 124 patients with non-traumatic neck pain and 68 asymptomatic subjects. Kinesiophobia partially explained lower craniocervical flexion ROM (p = .01) and lower peak velocity in flexion (P < .001). Age partially explained increased craniocervical extension ROM (P < .001) and lower peak velocity in flexion (P = .03). Chronicity partially explained increased lateral flexion conjunct motion (P = .008). All models showed low values of explained variance (< 32%) and low absolute values of regression coefficients. CONCLUSIONS: This study did not find a clear relationship between population characteristics and sensorimotor control variables associated with the craniocervical flexion movement. Kinesiophobia might have some association with reduced ROM in craniocervical flexion, but further research in this field is needed in large samples of patients with higher levels of kinesiophobia pain or disability.

Are Morphometric Alterations of the Deep Neck Muscles Related to Primary Headache Disorders? A Systematic Review.

This systematic review aims to summarise the evidence from studies that examined morphometric alterations of the deep neck muscles using diagnostic imaging (ultrasound imaging, magnetic resonance imaging, and computed tomography) in patients diagnosed with primary headache disorders (PHD). No previous reviews have focused on documenting morphometric changes in this population. We searched five databases (up to 12 November 2022) to identify the studies. The risk of bias (RoB) was assessed using the Quality in Prognostic Studies (QUIPS) tool and the overall quality of the evidence was assessed using The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. A total of 1246 studies were screened and five were finally included; most were at high RoB, and the overall level of confidence in results was very low. Only two studies showed a significant association between morphometric alterations of the deep neck muscles and PHD (p < 0.001); nevertheless, their RoB was high. Contradictory and mixed results were obtained. The overall evidence did not show a clear association between morphometric alterations of the deep neck muscles in patients diagnosed with PHD. However, due to the limited number of studies and low confidence in the evidence, it is necessary to carry out more studies, with higher methodological quality to better answer our question.

Potential Use of Wearable Inertial Sensors to Assess and Train Deep Cervical Flexors: A Feasibility Study with Real Time Synchronization of Kinematic and Pressure Data during the Craniocervical Flexion Test.

The aim of the study was to develop a novel real-time, computer-based synchronization system to continuously record pressure and craniocervical flexion ROM (range of motion) during the CCFT (craniocervical flexion test) in order to assess its feasibility for measuring and discriminating the values of ROM between different pressure levels. This was a descriptive, observational, cross-sectional, feasibility study. Participants performed a full-range craniocervical flexion and the CCFT. During the CCFT, a pressure sensor and a wireless inertial sensor simultaneously registered data of pressure and ROM. A web application was developed using HTML and NodeJS technologies. Forty-five participants successfully finished the study protocol (20 males, 25 females; 32 (11.48) years). ANOVAs showed large effect significant interactions between pressure levels and the percentage of full craniocervical flexion ROM when considering the 6 pressure reference levels of the CCFT (p < 0.001; η2 = 0.697), 11 pressure levels separated by 1 mmHg (p < 0.001; η2 = 0.683), and 21 pressure levels separated by 0.5 mmHg (p < 0.001; η2 = 0.671). The novel time synchronizing system seems a feasible option to provide real-time monitoring of both pressure and ROM, which could serve as reference targets to further investigate the potential use of inertial sensor technology to assess or train deep cervical flexors.

Does obesity affect patient-reported outcomes following total knee arthroplasty?

BACKGROUND: There is an existing perception that obesity has a negative impact on complications following total knee arthroplasty (TKA). However, data on the impact of obesity levels on patient-reported outcomes (PROMs) is sparse. We investigated the association between different obesity classes with PROMs among patients who underwent TKA. METHODS: We performed retrospective secondary analyses on data extracted from the total joint replacement data repository (Alberta, Canada) managed by the Alberta Bone and Joint Health Institute (ABJHI). Patients had WOMAC and EQ5D scores measured at baseline in addition to 3 and/or 12 months following TKA. Patients were stratified according to the World Health Organization (WHO) classification, into five body mass index (BMI) groups of normal, overweight, BMI class I, BMI class II, and BMI class III. The association between BMI and mean changes in WOMAC subscales (pain, function, and stiffness) and EQ-5D-5L index over the time intervals of baseline to 3 months and 3 to 12 months following TKA was assessed. Linear mixed-effects models were used, and the models were adjusted for age, sex, length of surgery, comorbidities, year of surgery, and geographical zone where the surgery was performed. RESULTS: Mean age was 65.5 years (SD = 8.7). Postoperatively, there was a significant improvement (p < 0.001) in WOMAC subscales of patient-reported pain, function, and stiffness, as well as EQ-5D-5L regardless of BMI group. Although, patients in BMI class II and class III reported significantly improved pain 3 months after TKA compared to those with normal BMI, all BMI groups attained similar level of pain reduction at 12 months after TKA. The greatest improvement in all WOMAC subscales, as well as EQ5D index, occurred between baseline and 3 months (adjusted p < 0.0001). CONCLUSION: The findings indicate that patients reported improved pain, function, and stiffness across all BMI groups following TKA. Patients with BMI classified as obese reported similar benefits to those with BMI classified as normal weight. These results may help health care providers to discuss expectations regarding the TKA recovery in terms of pain, function, and quality of life improvements with their TKA candidates.

Methodological Issues in Rehabilitation Research: A Scoping Review.

OBJECTIVE: To identify, synthesize, and categorize the methodological issues faced by the rehabilitation field. DATA SOURCES: A scoping review was conducted using studies identified in MEDLINE, the Cochrane Library, EMBASE, Web of Science, Scopus, Physiotherapy Evidence Database, and Google Scholar up to August 2018. STUDY SELECTION: We included all type of publications describing methodological issues in rehabilitation research where rehabilitation is described as a multimodal process. The methodological issues have been categorized and classified. DATA EXTRACTION: The synthesis included qualitative and quantitative analysis. To focus the attention on rehabilitation, we post hoc divided in "specific issues" (highly related to, even if not exclusive of, rehabilitation research) and "generic issues" (common in biomedical research). DATA SYNTHESIS: Seventy-one publications were included: 68% were narrative reviews, 15% systematic reviews, 7% editorials, 4% meta-epidemiologic studies, and 5% others. Specific methodological issues include the following: problematic application of randomized controlled trials (32%), absent definition of core outcome sets (28%), poor interventions description (22%), weak methodological (conducting) and reporting quality (21%), scarce clinical practice applicability (14%), lack of blinding assessor (10%), inadequate randomization methods or inadequate allocation concealment (8%), and inadequate participants description and recruitment (8%). "Generic" issues included the following: data and statistical description (31%), authors' methodological training (7%), peer review process (6%, n=4), funding declaration (6%), ethical statement (3%), protocol registration (3%), and conflict of interest declaration (1%). CONCLUSIONS: Methodological and reporting issues might influence the quality of the evidence produced in rehabilitation research. The next steps to move forward in the field of rehabilitation could be to evaluate the influence of all these issues on the validity of trial results through meta-epidemiologic studies and to develop specific checklists to provide guidance to authors to improve the reporting and conduct of trials in this field.

Tools to Assess the Risk of Bias and Reporting Quality of Randomized Controlled Trials in Rehabilitation.

OBJECTIVES: (1) To determine whether new tools and items have been developed to evaluate the risk of bias (RoB) and reporting of randomized controlled trials (RCTs) in rehabilitation; (2) to determine which items are included in the existing reporting guidelines, and to create a matrix of items to report and conduct trials in rehabilitation as the first step for a starting a rigorous validation process. DATA SOURCES: Searches were conducted in MEDLINE, EMBASE, and Cumulative Index to Nursing and Allied Health databases. STUDY SELECTION: Studies should describe a newly developed tool to evaluate the RoB or quality of reporting for RCTs in the area of rehabilitation. DATA EXTRACTION: (1) First, we extracted items from new tools identified by the electronic search strategies and then (2) we looked at the items provided by the Consolidated Standards of Reporting Trials statement and its relevant extensions. We determined whether these items were already included in our matrix of items. Items were classified based on methodological domains they accomplish, biases they were able to target, and whether they guide reporting or conduct. DATA SYNTHESIS: Among the 1596 citations found, 23 articles were potentially relevant. From these, only 3 new scales (National Institute for Complementary Medicine Acupuncture Network, Quality of reports on spa and balneotherapy [SPAC], Assessment of Study Quality and Reporting in Exercise) were found. In addition, the newly updated Cochrane RoB tool (RoB 2.0) was included. Our matrix contained 122 unique items for any rehabilitation area, 46 items (37.7%) were related to conduct, and 58 (47.5%) were related to the reporting; 18 (14.8%) were related to both. Overall, 76 new items were added among all domains. CONCLUSIONS: Many individual and diverse items have been used to guide the reporting and conduct of rehabilitation trials. This indicates a great variability in number of items and an apparent lack of consensus on a core set of items to be used in rehabilitation. Future research should look into developing a core set of items for the rehabilitation field.

Influence of Sponsorship Bias on Treatment Effect Size Estimates in Randomized Trials of Oral Health Interventions: A Meta-epidemiological Study.

BACKGROUND: In this meta-epidemiological study, we aimed to examine associations between treatment effect size estimates and sponsorship bias in oral health randomized clinical trials. METHODS: We selected oral health related meta-analyses that included a minimum of five randomized controlled trials. We extracted data, in duplicate, related to influence of sponsorship bias. We quantified the extent of bias associated with influence of sponsorship on the magnitude of effect size estimates of continuous variables using a two-level meta-meta-analytic approach with random-effects models to allow for intra- and inter-meta-analysis heterogeneity. RESULTS: We initially identified 540 randomized trials included in 64 meta-analyses. Risk of sponsorship bias was judged as being "unclear" in 72.8% (n = 393) of the trials, while it was assessed as "low" in 16.7% (n = 90) and as "high" in 10.6% (n = 57) of the trials. Using a meta-epidemiological analysis (37 meta-analyses, including 328 trials that analyzed 85,934 patients), we identified statistically significant larger treatment effect size estimates in trials that had "high or unclear" risk of sponsorship bias (difference in treatment effect size estimates=0.10; 95% confidence intervals: 0.02 to 0.19) than in trials that had "low" risk of sponsorship bias. CONCLUSIONS: We identified significant differences in treatment effect size estimates between dental trials based on sponsorship bias. Treatment effect size estimates were 0.10 larger in trials with "high or unclear" risk of sponsorship bias. PRACTICAL IMPLICATIONS: Clinicians should have an adequate knowledge of sponsorship bias in a clinical trial and be able to estimate the degree to which the conclusions of a systematic review are synthesized and interpreted, based on trials with low risk of sponsorship bias.

A novel use of inertial sensors to measure the craniocervical flexion range of motion associated to the craniocervical flexion test: an observational study.

BACKGROUND: The craniocervical flexion test (CCFT) is recommended when examining patients with neck pain related conditions and as a deep cervical retraining exercise option. During the execution of the CCFT the examiner should visually assess that the amount of craniocervical flexion range of motion (ROM) progressively increases. However, this task is very subjective. The use of inertial wearable sensors may be a user-friendly option to measure and objectively monitor the ROM. The objectives of our study were (1) to measure craniocervical flexion range of motion (ROM) associated with each stage of the CCFT using a wearable inertial sensor and to determine the reliability of the measurements and (2) to determine craniocervical flexion ROM targets associated with each stage of the CCFT to standardize their use for assessment and training of the deep cervical flexor (DCF) muscles. METHODS: Adults from a university community able to successfully perform the CCFT participated in this study. Two independent examiners evaluated the CCFT in two separate sessions. During the CCFT, a small wireless inertial sensor was adhered to the centre of the forehead to provide real-time monitoring and to record craniocervical flexion ROM. The intra- and inter-rater reliability of the assessment of craniocervical ROM was calculated. This study was approved by the Research Ethics Committee of CEU San Pablo University (236/17/08). RESULTS: Fifty-six participants (18 males, 23 females; mean [SD] age, 21.8 [3.45] years) were included in the study and successfully completed the study protocol. All interclass correlation coefficient (ICC) values indicated good or excellent reliability of the assessment of craniocervical ROM using a wearable inertial sensor. There was high variability between subjects on the amount of craniocervical ROM necessary to achieve each stage of the CCFT. CONCLUSIONS: The use of inertial sensors is a reliable method to measure the craniocervical flexion ROM associated with the CCFT. The great variability in the ROM limits the possibility to standardize a set of targets of craniocervical flexion ROM equivalent to each of the pressure targets of the pressure biofeedback unit.

Relationship Between Intensity of Neck Pain and Disability and Shoulder Pain and Disability in Individuals With Subacromial Impingement Symptoms: A Cross-Sectional Study.

OBJECTIVE: This study aimed to verify a possible relationship between shoulder disability and shoulder pain intensity and the variables related to cervical-spine dysfunction, and determine which of these can differentiate moderate to severe shoulder pain (>4 on a numerical rating scale [NRS]) from mild shoulder pain (≤4 on the NRS) in individuals with subacromial impingement symptoms. METHODS: One hundred and forty volunteers with shoulder pain were evaluated. Demographic information and variables related to the shoulder and neck were collected. Self-reported pain and disability of the shoulder and cervical spine were measured using the Shoulder Pain and Disability Index (SPADI) and Neck Disability Index (NDI) questionnaires, respectively. An NRS was used to measure pain in the shoulder and cervical spine. A purposeful modeling strategy was used to determine the best model to predict shoulder disability and shoulder pain (dependent variables). Multiple logistic regression analysis followed by receiver operating curve analysis was used to determine which variables better differentiated moderate to severe shoulder pain from mild shoulder pain. RESULTS: Variables such as Neck Disability Index (NDI) score (ß = 1.09, P = .00) and age (ß = -0.19, P = .03) were associated with the total SPADI score. Neck pain was significantly associated with shoulder pain (ß = 0.40, P = .00). The combination of variables predicting moderate to severe shoulder pain was total SPADI score (odds ratio [OR] = 1.15, P = .003), neck pain (OR = 3.20, P = .04), and age (OR = 1.01, P = .05). CONCLUSION: Our results demonstrate the important connection between shoulder- and neck-related symptoms in individuals with subacromial impingement symptoms.

Effectiveness of mobilisation of the upper cervical region and craniocervical flexor training on orofacial pain, mandibular function and headache in women with TMD. A randomised, controlled trial.

BACKGROUND: Studies exploring interventions targeting the cervical spine to improve symptoms in patients with temporomandibular disorders (TMD) are limited. OBJECTIVES: To determine whether mobilisation of the upper cervical region and craniocervical flexor training decreased orofacial pain, increased mandibular function and pressure pain thresholds (PPTs) of the masticatory muscles and decreased headache impact in women with TMD when compared to no intervention. METHODS: In a single-blind randomised controlled trial, 61 women with TMD were randomised into an intervention group (IG) and a control group (CG). The IG received upper cervical mobilisations and neck motor control and stabilisation exercises for 5 weeks. The CG received no treatment. Outcomes were collected by a blind rater at baseline and 5-week follow-up. Orofacial pain intensity was collected once a week. A mixed ANOVA and Cohen's d were used to determine differences within/between groups and effect sizes. RESULTS: Pain intensity showed significant time-by-group interaction (P < 0.05), with significant between-group differences at four and five weeks (P < 0.05), with large effect sizes (d > 0.8). The decrease in orofacial pain over time was clinically relevant only in the IG. Change in headache impact was significantly different between groups, and the IG showed a clinically relevant decrease after the treatment. No effects were found for PPT or mandibular function. CONCLUSION: Women with TMD reported a significant decrease in orofacial pain and headache impact after 5 weeks of treatment aimed at the upper cervical spine compared to a CG.

Influence of blinding on treatment effect size estimate in randomized controlled trials of oral health interventions.

BACKGROUND: Recent methodologic evidence suggests that lack of blinding in randomized trials can result in under- or overestimation of the treatment effect size. The objective of this study is to quantify the extent of bias associated with blinding in randomized controlled trials of oral health interventions. METHODS: We selected all oral health meta-analyses that included a minimum of five randomized controlled trials. We extracted data, in duplicate, related to nine blinding-related criteria, namely: patient blinding, assessor blinding, care-provider blinding, investigator blinding, statistician blinding, blinding of both patients and assessors, study described as "double blind", blinding of patients, assessors, and care providers concurrently, and the appropriateness of blinding. We quantified the impact of bias associated with blinding on the magnitude of effect size using a two-level meta-meta-analytic approach with a random effects model to allow for intra- and inter-meta-analysis heterogeneity. RESULTS: We identified 540 randomized controlled trials, included in 64 meta-analyses, analyzing data from 137,957 patients. We identified significantly larger treatment effect size estimates in trials that had inadequate patient blinding (difference in treatment effect size = 0.12; 95% CI: 0.00 to 0.23), lack of blinding of both patients and assessors (difference = 0.19; 95% CI: 0.06 to 0.32), and lack of blinding of patients, assessors, and care-providers concurrently (difference = 0.14; 95% CI: 0.03 to 0.25). In contrast, assessor blinding (difference = 0.06; 95% CI: -0.06 to 0.18), caregiver blinding (difference = 0.02; 95% CI: -0.04 to 0.09), principal-investigator blinding (difference = - 0.02; 95% CI: -0.10 to 0.06), describing a trial as "double-blind" (difference = 0.09; 95% CI: -0.05 to 0.22), and lack of an appropriate method of blinding (difference = 0.06; 95% CI: -0.06 to 0.18) were not associated with over- or underestimated treatment effect size. CONCLUSIONS: We found significant differences in treatment effect size estimates between oral health trials based on lack of patient and assessor blinding. Treatment effect size estimates were 0.19 and 0.14 larger in trials with lack of blinding of both patients and assessors and blinding of patients, assessors, and care-providers concurrently. No significant differences were identified in other blinding criteria. Investigators of oral health systematic reviews should perform sensitivity analyses based on the adequacy of blinding in included trials.

Psychometric properties of Hope Scales: A systematic review.

INTRODUCTION: Hope is recognised as an important factor in health, illness, and well-being. Many scales to measure hope have been developed and used in various disciplines, yet, their psychometric properties have not been systematically reviewed. AIM: To systematically review the psychometric properties of hope scales. DESIGN: Systematic review. METHODS: Four electronic databases were searched followed by a hand search. The data were extracted and qualitatively evaluated by the COSMIN checklist, an instrument designed as a quality rating tool for systematic reviews of psychometric properties. RESULTS: From 1271 retrieved abstracts, 68 papers met the inclusion criteria. The most used scale was the Snyder Hope Scale (46%) followed by the Herth Hope Index (16%). All other scales (n = 16) were evaluated in less than 10% of the papers. Structural validity (91%), internal consistency (88%), and hypothesis testing (74%) were the most reported properties. Reliability (34%), cross-cultural validity (34%), content validity (25%), and criterion validity (15%) were reported in less than 50% of the papers. Only two (3%) studies reported responsiveness, and none reported measurement error. Less than 35% of the validation studies achieved excellent or good quality for any of the measurement properties. CONCLUSION: The results show that no robust and valid scale exists for measuring hope. It highlights important gaps in psychometric properties of hope scales. Despite more than 40 years of research and development of hope scales, the currently available scales do not meet the standards of psychometric evaluation. This calls for efforts to improve the quality of hope scales.

Adherence and Attrition in Fall Prevention Exercise Programs for Community-Dwelling Older Adults: A Systematic Review and Meta-Analysis.

Fall prevention exercise programs have been reported to be effective in minimizing falls in older adults. However, adherence and attrition in exercise programs remain a challenge. This study reviewed the evidence on how levels of adherence and attrition in fall prevention exercise programs may affect magnitude of effect of fall risk reduction in community-dwelling older adults. A systematic review and meta-analysis of randomized controlled trials on fall prevention exercise programs for community-dwelling older adults aged 65+ years published between 2005 and 2016 from six databases were undertaken. Twenty articles met inclusion criteria. Results showed that program adherence >80% may result in greater fall risk reduction compared to lower levels of adherence. A possible inverse relationship exists between attrition levels and effect sizes of fall prevention exercise programs. Future studies should properly report falls/fallers and a consensus on a standardized measure for reporting adherence to fall prevention exercise programs is recommended.

Predictive value of the DASH tool for predicting return to work of injured workers with musculoskeletal disorders of the upper extremity.

OBJECTIVES: To determine whether the Disabilities of the Arm, Shoulder, and Hand (DASH) tool added to the predictive ability of established prognostic factors, including patient demographic and clinical outcomes, to predict return to work (RTW) in injured workers with musculoskeletal (MSK) disorders of the upper extremity. METHODS: A retrospective cohort study using a population-based database from the Workers' Compensation Board of Alberta (WCB-Alberta) that focused on claimants with upper extremity injuries was used. Besides the DASH, potential predictors included demographic, occupational, clinical and health usage variables. Outcome was receipt of compensation benefits after 3 months. To identify RTW predictors, a purposeful logistic modelling strategy was used. A series of receiver operating curve analyses were performed to determine which model provided the best discriminative ability. RESULTS: The sample included 3036 claimants with upper extremity injuries. The final model for predicting RTW included the total DASH score in addition to other established predictors. The area under the curve for this model was 0.77, which is interpreted as fair discrimination. This model was statistically significantly different than the model of established predictors alone (p<0.001). When comparing the DASH total score versus DASH item 23, a non-significant difference was obtained between the models (p=0.34). CONCLUSIONS: The DASH tool together with other established predictors significantly helped predict RTW after 3 months in participants with upper extremity MSK disorders. An appealing result for clinicians and busy researchers is that DASH item 23 has equal predictive ability to the total DASH score.

Non-pharmacological cancer pain interventions in populations with social disparities: a systematic review and meta-analysis.

INTRODUCTION: Global advances in pain relief have improved the quality of life of cancer populations. Yet, variation in cancer pain outcomes has been found in populations with social disparities compared to mainstream groups. Populations with social disparities bear an inequitable distribution of resources such as ethnic minorities, low income individuals, and women in vulnerable circumstances. RESEARCH PURPOSE: A systematic review and meta-analysis of the effect of non-pharmacological cancer pain interventions in cancer populations with social disparities of income, ethnicity, or gender. METHODS: Randomized controlled trials, controlled trials, and before and after studies were targeted through comprehensive multidatabase searches. Two reviewers independently screened titles/abstracts for potentially relevant studies and reviewed the full text of relevant articles for inclusion. Data were extracted from included studies by one reviewer and verified by another reviewer. Four reviewers independently completed quality assessment. Studies were grouped by intervention. Effects were evaluated for heterogeneity and pooled. RESULTS: The search found 5219 potential records. Full text of 26 reports was evaluated. Three randomized controlled trials (RCTs) met inclusion criteria, targeting ethnic minorities and underserved populations and/or women. Interventions included education, coaching, and online support groups. Studies found no significant differences in pain reduction between intervention and control groups or between ethnic minorities and their counterparts. A high risk of bias was found in all studies. Meta-analysis found no statistically significant difference on pain intensity among underserved groups, ethnic minorities, or between ethnic minorities and white counterparts. CONCLUSION: Results show the need to examine supportive care interventions particularly in populations with social disparities.

An investigation of the validity of the Work Assessment Triage Tool clinical decision support tool for selecting optimal rehabilitation interventions for workers with musculoskeletal injuries.

OBJECTIVE: To evaluate the concurrent validity of a clinical decision support tool (Work Assessment Triage Tool (WATT)) developed to select rehabilitation treatments for injured workers with musculoskeletal conditions. DESIGN: Methodological study with cross-sectional and prospective components. SETTING: Data were obtained from the Workers' Compensation Board of Alberta rehabilitation facility in Edmonton, Canada. SUBJECTS: A total of 432 workers' compensation claimants evaluated between November 2011 and June 2012. MAIN MEASURES: Percentage agreement between the Work Assessment Triage Tool and clinician recommendations was used to determine concurrent validity. In claimants returning to work, frequencies of matching were calculated and compared between clinician and Work Assessment Triage Tool recommendations and the actual programs undertaken by claimants. The frequency of each intervention recommended by clinicians, Work Assessment Triage Tool, and case managers were also calculated and compared. RESULTS: Percentage agreement between clinician and Work Assessment Triage Tool recommendations was poor (19%) to moderate (46%) and Kappa = 0.37 (95% CI -0.02, 0.76). The Work Assessment Triage Tool did not improve upon clinician recommendations as only 14 out of 31 claimants returning to work had programs that contradicted clinician recommendations, but were consistent with Work Assessment Triage Tool recommendations. Clinicians and case managers were inclined to recommend functional restoration, physical therapy, or no rehabilitation while the Work Assessment Triage Tool recommended additional evidence-based interventions, such as workplace-based interventions. CONCLUSIONS: Our findings do not provide evidence of concurrent validity for the Work Assessment Triage Tool compared with clinician recommendations. Based on these results, we cannot recommend further implementation of the Work Assessment Triage Tool. However, the Work Assessment Triage Tool appeared more likely than clinicians to recommend interventions supported by evidence; thus warranting further research.

Clinical Decision Support Tools for Selecting Interventions for Patients with Disabling Musculoskeletal Disorders: A Scoping Review.

Purpose We aimed to identify and inventory clinical decision support (CDS) tools for helping front-line staff select interventions for patients with musculoskeletal (MSK) disorders. Methods We used Arksey and O'Malley's scoping review framework which progresses through five stages: (1) identifying the research question; (2) identifying relevant studies; (3) selecting studies for analysis; (4) charting the data; and (5) collating, summarizing and reporting results. We considered computer-based, and other available tools, such as algorithms, care pathways, rules and models. Since this research crosses multiple disciplines, we searched health care, computing science and business databases. Results Our search resulted in 4605 manuscripts. Titles and abstracts were screened for relevance. The reliability of the screening process was high with an average percentage of agreement of 92.3 %. Of the located articles, 123 were considered relevant. Within this literature, there were 43 CDS tools located. These were classified into 3 main areas: computer-based tools/questionnaires (n = 8, 19 %), treatment algorithms/models (n = 14, 33 %), and clinical prediction rules/classification systems (n = 21, 49 %). Each of these areas and the associated evidence are described. The state of evidentiary support for CDS tools is still preliminary and lacks external validation, head-to-head comparisons, or evidence of generalizability across different populations and settings. Conclusions CDS tools, especially those employing rapidly advancing computer technologies, are under development and of potential interest to health care providers, case management organizations and funders of care. Based on the results of this scoping review, we conclude that these tools, models and systems should be subjected to further validation before they can be recommended for large-scale implementation for managing patients with MSK disorders.
