A qualitative inquiry to explore management of distal radius fracture by certified hand therapists.

BACKGROUND: Distal radius fractures (DRF) are extremely common in middle-aged and elderly. Certified Hand Therapists (CHT) are experts in managing hand injuries including DRF. PURPOSE: Using qualitative methodology, this study examined practice patterns among CHT and understand prevalent common patterns in managing DRF. STUDY DESIGN: Descriptive qualitative study. METHODS: This study utilized a qualitative descriptive method with an inductive approach to discern the practices of CHT in managing DRF. A purposive sample of practicing CHT was assembled. A semi-structured interview guide facilitated qualitative interviews using open-ended questions to assess practices of CHT in the domains of assessment, interventions, and appropriateness for discharge. Two student physical therapists transcribed the interviews, which were verified by a third rater for accuracy. Thematic content analysis guided the coding and analyses of the interview data. A two-phase coding process was conducted using Nvivo software. Two study authors developed initial codebook and completed subsequent analysis of transcripts. RESULTS: Of the 12 participants, five were PT and seven were OT with an average experience of 14.1 years as a CHT. Practice patterns across domains were largely consistent among CHT. All CHTs reported inquiring about severity of displacement of DRF, orthopedic management, comorbidities, and medical history as well as examining wrist/hand range of motion (ROM), grip strength (GS), and wrist functions (n = 12). A large majority administered outcome measures and performed sensory and integumentary assessment. Patient education regarding injury and exercises was the key element for interventions. Adequate gains in GS, wrist functions, wrist ROM, and ability to use wrist/hand for functional tasks were the key benchmarks for discharge from care. DISCUSSION: Most practice behaviors were common among CHTs while managing DRF. Some variations exist depending whether their primary discipline is PT or OT. The results highlight knowledge-to-action gap, where most CHTs do not integrate fall-risk management in DRF. CONCLUSIONS: This study identified common practice patterns among CHTs in managing DRF while also identifying opportunity to improve practice by integrating assessment of balance and fall-risk.

Rasch Analysis of Joint Replacement Version for Hip Disability and Osteoarthritis Outcome in Individuals With Advanced Osteoarthritis of Hip Awaiting Total Hip Arthroplasty Surgery.

OBJECTIVE: The objective of this study was to examine measurement properties of the Joint replacement version for Hip Disability and Osteoarthritis Outcome Score (HOOS-JR) using Rasch analysis in patients with osteoarthritis of hip (HOA). DESIGN: Cross-sectional clinical measurement SETTING: Patient outcomes database at a tertiary care hospital PARTICIPANTS: Convenience sampling of patients with HOA scheduled for total hip arthroplasty (N=327) OUTCOME MEASURES AND ANALYSIS: The data for pre-surgery assessments for patients with HOA were extracted from an existing database. Variables extracted included HOOS-JR scores, demographic information (age, sex), health-related data, and anthropometric variables. The assumptions of Rasch model such as the test of fit, fit residuals, ordering of item thresholds, factor structure, DIF, internal consistency and Pearson separation index were examined for the HOOS-JR scores. RESULTS: The HOOS-JR showed adequate overall fit to the Rasch model, logically ordered response thresholds, no floor or ceiling effects, and high internal consistency (Cronbach's alpha of 0.91). The HOOS-JR did not satisfy the assumption of unidimensionality, albeit the violation of this assumption was marginal (6.12% over 5%). Person-item threshold distribution (difference between person and item means were equal to 0.92 which was less than 1 logit unit) confirmed that the HOOS-JR scores were well targeted. CONCLUSIONS: Given that the violation of unidimensionality for HOOS-JR was marginal, we recommend further studies to validate this finding. Results broadly support the use of HOOS-JR for assessing hip health in patients with HOA.

Validity and Accuracy of the Tilburg Frailty Indicator Part B for Identification of Frailty in Older Adults Consulting a Rural Geriatric Medicine Clinic.

The Tilburg Frailty Indicator (TFI) is a validated tool for determining frailty in older adults. This study examined the validity and accuracy of the TFI Part B (TFI-B) in a North American context. Seventy-two individuals ≥ 65 years of age recruited from a rural geriatric medicine clinic completed a set of self-reported and performance-based measures, including TFI-B. Frailty level was determined using modified Fried's Frailty Phenotype (FFP). Pearson correlation coefficients (r) assessed the concurrent relationships between the TFI-B and other measures. Accuracy of the TFI-B in classifying frailty level was assessed using assessing area under the curve (AUC). The TFI-B scores showed low correlations (r < 0.4) with gait speed and grip, suggesting that the TFI-B did not consider frailty as merely a physical problem. The AUC of 0.82 indicated that the TFI-B scores accurately classified frail versus non-frail individuals. The score of ≥ 5 on the TFI-B scores showed satisfactory sensitivity/specificity (73%/77%) and excellent negative predictive value (91.95%). This indicates that a TFI-B score of < 5 can be used to rule out frailty.

Severity of persistent pain and disability can accurately screen for presence of pain catastrophizing and fear of performing wrist movements in individuals with distal radius fracture.

BACKGROUND: The evidence indicating presence of psychological factors concerns in individuals who report persistent residual pain and disability over a longer term after distal radius fractures (DRF) is emerging but requires further inquiry. OBJECTIVES: To examine the associations of persistent wrist pain and disability at 6-months after DRF with the presence of psychological factors. METHODS: Eighty-five patients with DRF were evaluated for wrist pain and disability with subscales of Patient-rated wrist evaluation (PRWE), 6-months after the fracture. The associations of wrist pain and disability with these psychological factors at 6-months after DRF were examined using multivariable logistic regression models. The ability of PRWE scores at 6-months after DRF to accurately classify individuals with and without these psychological factors was examined using the area under the receiver operating characteristic curve (AUC). RESULTS: Higher PRWE-P scores were significantly associated with worse pain catastrophizing, having emotional distress, and fear of performing wrist movements. In addition, higher PRWE-F scores were also highly associated with worse pain catastrophizing, having emotional distress, and fear of performing wrist movements. The PRWE-P or PRWE-F Scores of ≥18/50 showed the best combination of sensitivity and specificity in identifying individuals with pain catastrophizing, emotional distress, and fear of performing wrist movements at 6-months after DRF (AUC values of ≥0.88). CONCLUSION: The novel finding of this study is that scores of ≥18/50 PRWE-P or PRWEF can be used to screen for the presence of these psychological factors.

Rasch Analysis for the Knee Injury and Osteoarthritis Outcome Score Joint Replacement Version in Individuals Awaiting Total Knee Replacement Surgery.

The aim of this study was to verify the single-factor structure of the joint replacement version of the Knee Injury and Osteoarthritis Outcome Score (KOOS-JR) and examine its measurement properties in the context of Rasch analysis in patients with end-stage osteoarthritis of the knee (KOA) awaiting total knee replacement (TKR). The study design was retrieval of prospectively collected clinical data. The data were extracted from the presurgery visit for individuals with KOA who were scheduled for primary TKR at a tertiary care hospital. Those who were scheduled for revision of TKR had any other lower extremity injury or surgery during 6 months prior to the presurgery visit, or those who had reported pre-existing neurological impairments affecting the lower extremity functions were excluded during data extraction. The assumptions of Rasch analysis that were examined included the test of fit, fit of residuals, ordering of item thresholds, Pearson separation index, differential item functioning (DIF), dependency, and unidimensionality. The main outcome measure was KOOS-JR. Data were extracted for 283 patients, including 112 men and 160 women, from clinical charts. The KOOS-JR demonstrated good overall fit to the Rasch model. However, it failed to meet the assumption of unidimensionality. None of the items demonstrated DIF or concerns with response thresholds. Person-item threshold distribution indicated that the score for KOOS-JR overestimated person traits with floor and ceiling effects. Reliability statistics were equal to 0.9, suggesting that seven items within the KOOS-JR were internally consistent and reliable. The hypothetical unidimensional KOOS-JR could not be reproduced in our sample in that KOOS-JR had a latent construct. Future research should perform exploratory factor analysis to examine this latent construct.

Smartphone goniometer has excellent reliability between novice and experienced physical therapists in assessing knee range of motion.

INTRODUCTION: Smartphone app-based goniometer (SG) are emerging as an alternative to Universal Goniometers (UG) in assessing joint range of motion (ROM). This study examined whether the experience level of examiner affected the reliability of assessing knee flexion (KF) and knee extension (KE) ROM using UG and SG. METHODS: Participants with osteoarthritis of the knee or following total knee replacement were recruited. KF and KE ROM using UG and SG were assessed twice by an experienced physical therapist (PT) and a student PT (SPT). Intraclass correlation coefficients (ICC) examined the interrater (experienced PT vs SPT) and intrarater reliabilities (for experienced PT and SPT) in assessing KF and KE ROM for UG and SG. Concurrent relationships were examined between the knee ROM with pain and physical function using Pearson Correlation Coefficient (r). RESULTS: The interrater reliability in assessing KF and KE ROM was excellent (ICC>0.90) between novice and experienced examiners. The standard error of measurement (SEM) for novice examiner in assessing KF was 1° and 2° while using UG and SG respectively; whereas the SEM for experienced examiner in assessing KF was 1° irrespective of which device was used. The concurrent relationships between KF and KE ROM with measures of pain and function were divergent (moderate to low correlations; r <0.7; p > 0.05). CONCLUSION: Both UG and SG have smaller measurement error in assessing KF and KE ROM irrespective of experience level of examiner and therefore no one tool is superior than the other for assessing knee ROM in clinical practice.

Measurement Properties of Outcome Measures Used to Assess Physical Impairments in Patients After Distal Radius Fracture: A Systematic Review.

OBJECTIVES: Individuals with distal radius fractures (DRF) may experience difficulty with gripping an object, painful wrist movements, sensorimotor difficulties, and swelling around the wrist and hand. A comprehensive review of the existing evidence concerning the measurement properties of common physical impairment measures can provide a valuable resource to guide hand therapy practice while managing DRF. The primary objective was to locate and assess the quality of literature on the measurement properties for the measures of physical impairment used in individuals with DRF. METHODS: Two reviewers searched PubMed, CINAHL, and EMBASE. A combination of DRF, measurement properties, and physical impairments were used as keywords, and articles were independently assessed using the Consensus-Based Standards for the Selection of Health Measurement Instruments critical appraisal tool. Primary studies were included if they examined at least 1 of the following: reliability, validity, responsiveness, or indices of true and meaningful changes for measures of physical impairment in the DRF sample. A total of 19 articles were included in this review. The quality of the studies ranged from 46% to 92%. This review suggests that measures such as assessment of grip strength and supination and pronation range of motion (ROM), using various goniometric devices, showed good intrarater and interrater reliability, construct validity, and responsiveness in individuals with DRF. CONCLUSION: Acceptable reliability and responsiveness were reported in grip and wrist ROM assessments for measuring changes in wrist and hand function after DRF; however, wrist ROM assessed using traditional goniometric techniques were less reliable in individuals with DRF. IMPACT: This study provides insight into which objective tools might be better suited for measuring outcomes related to DRF.

Virtual assessments of knee and wrist joint range motion have comparable reliability with face-to-face assessments.

BACKGROUND: There has been increased usage of virtual telerehabilitation approach during the COVID-19 pandemic. It is crucial to establish reliability of conducting virtual assessments for musculoskeletal conditions. OBJECTIVES: This research determined the intra- and interrater reliability of measuring knee and wrist range of motion (ROM) assessed virtually and obtained face-to-face (F2F) using a goniometer (UG) for a student and an experienced examiner. METHOD: Knee and wrist joint ROM for 54 healthy participants was assessed virtually and F2F by a student examiner and an experienced physical therapist. Intra- (virtual vs. UG assessment) and inter-rater (virtual or UG assessment between examiners) reliabilities were examined for all ROM using Intraclass correlation coefficient (ICC). The ICC values were considered good (>0.75) or excellent (>0.90). Bland and Altman plots determined the limits of agreement (LOA) in assessing joint ROM. RESULTS/FINDINGS: Student examiner had good reliability in virtually estimating knee extension (ICC = 0.79), wrist flexion (ICC = 0.82) and wrist extension (ICC = 0.78), whereas the experienced examiner had excellent reliability in virtually estimating all knee and wrist ROM (ICC > 0.90). The LOA in assessing knee and wrist ROM for the student examiner were wider indicating higher disagreement between virtual and UG-obtained ROM in some cases. CONCLUSIONS: Virtual estimation of knee and wrist ROM is a reliable technique, however experience level impacts the precision of measurement. It is suggested that the same examiner conducts all the ROM assessments throughout the clinical course of a patient receiving virtual interventions for knee or wrist pathologies.

Using Carpal Tunnel Questionnaire in clinical practice: A systematic review of its measurement properties.

INTRODUCTION: Carpal Tunnel Questionnaire (CTQ) is widely used for assessing condition-specific impairments in individuals with carpal tunnel syndrome (CTS) or for assessing outcomes after carpal tunnel surgery (carpal tunnel release [CTR]). A systematic review of its measurement properties can greatly facilitate its evidence-based use in clinical practice. The purpose of this study was to systematically locate, appraise, and synthesize the evidence concerning the reliability, responsiveness, validity, minimal detectable change (MDC), and minimal clinically important difference (MCID) for the CTQ and its scales. STUDY DESIGN: This is a systematic review of measurement properties. METHODS: Using predefined keywords, PubMed, CINAHL, PsychInfo, and ProQuest were searched to locate primary studies that assessed measurement properties of the CTQ. The methodological quality of the included studies was assessed using a standardized tool. Data concerning the measurement properties were extracted and synthesized. The pooled estimates for the indices of test-retest reliability, standard error of measurement, responsiveness, MDC, and MCID were calculated from the included studies. RESULTS: A total of 34 articles were deemed eligible and included in this review. The methodological quality of these 34 studies was generally good. Most studies suggested that the CTQ and its scales had good test-retest reliability and internal consistency. However, few studies found that the Symptom Severity Scale had more than one factor. The responsiveness of the CTQ and its scales was excellent across the studies. The pooled estimates for the MDC90 and MCID for Symptom Severity Scale/Functional Status Scale were 0.72/0.79 and 1.05/1.13, respectively. DISCUSSION: The results of this review support the use of CTQ and its scales in assessing conditions-specific impairments in individuals with CTS or after CTR. However, an effort should be made to review and modify the content of the symptom severity scale due to multiple reports challenging its unidimensional structure. CONCLUSIONS: The totality of evidence emerging from this systematic review suggests that the CTQ and its scales provide reliable and valid estimate of impairments resulting from CTS or after CTR.

Validation of Physical Performance Tests in Individuals with Advanced Knee Osteoarthritis.

BACKGROUND: Individuals with advanced osteoarthritis (OA) of the knee experience significant impairments in balance and in essential physical functions such as walking and rising from a chair. There is limited evidence on valid outcome measures to capture these impairments. QUESTIONS/PURPOSES: We sought to examine the construct validity of three physical performance measures in patients with advanced knee OA: a gait speed (GS) test, the Short Physical Performance Battery (SPPB), and the Timed Up and Go (TUG) test. METHODS: We designed a cross-sectional clinical measurement study in which patients with advanced knee OA completed two self-reported measures: the Knee Injury and Osteoarthritis Outcome Score-Physical Function Shortform (KOOS-PS) and a four-part numeric pain rating scale (Q-NPRS). They were also administered the GS test, TUG test, and SPPB. Convergent and divergent construct validity were assessed by examining relationships between the GS test, the SPPB, the TUG test, the KOOS-PS, and the Q-NPRS and calculating Pearson correlation coefficients (r). The scores for the GS, TUG test, and SPPB were compared with established normative values for age-matched healthy controls. RESULTS: Forty-four subjects (mean age, 66.9 ± 8.1 years) participated in the study. The GS test showed low concordance with the SPPB component tests and the TUG test. The relationships between the physical performance measures and the self-reported measures were low. The scores for the GS test, TUG test, and SPPB in our sample were significantly worse when compared with age-matched normative values, indicating impairments in physical performance. CONCLUSION: These results advance the understanding of the validity of the GS test, TUG test, and SPPB in demonstrating the impairments in physical performance that patients with advanced knee OA experience in walking, balancing, and rising from a chair. Future research should examine the reproducibility and responsiveness of the GS test, TUG test, and SPPB in patients with advanced knee OA, in order to facilitate the integration of these measures into clinical practice.

Developing and Validating a Step Test of Aerobic Fitness among Elementary School Children.

Purpose: The tests to estimate aerobic fitness among children require substantial space and maximum effort, which is often difficult for children. We developed a simple submaximal step test (Step Test of Endurance for Pediatrics, or STEP) and assessed its reliability, validity, and ability to estimate aerobic fitness among elementary school children. Method: Children aged 5-10 years completed the STEP with a protocol consisting of 0.1-, 0.2-, and 0.3-metre (4, 8, and 12 in.) step heights. Participants underwent treadmill testing with open circuit spirometry to determine actual maximal oxygen consumption (V̇o2max). Intra-class correlation coefficients (ICCs) assessed test-retest reliability of the STEP and its component tests. Multivariate linear regression assessed the associations between the STEP and V̇o2max, adjusting for potential covariates such as age, sex, BMI, and comorbidity count. Results: The STEP showed excellent reliability (ICC ≥ 0.92; N = 170), irrespective of effort level during testing. Significant effort issues and collinearity among the independent variables led us to exclude children aged 5-6 years (n = 45) from the regression analysis. The final regression model for children aged 7-10 years with adequate effort (n = 111), as defined by a respiratory exchange ratio of 1.0 or more, showed that the STEP, sex, and BMI were significantly predictive of V̇o2max (R 2 = 0.51). Conclusions: This new, effort-independent step test can estimate the aerobic fitness of children aged 7-10 years. Regression equations to estimate V̇o2max from the STEP were provided.

Objectif : les tests d'évaluation de la capacité aérobique chez les enfants exigent beaucoup d'espace et un effort maximal, et les enfants éprouvent souvent de la difficulté à les exécuter. La présente étude visait à mettre à l'essai un simple test sous-maximal de la marche d'escalier (test de la marche d'escalier pour établir l'endurance en pédiatrie, ou STEP, selon l'acronyme anglais) et à en déterminer la fiabilité, la validité et la capacité à évaluer la capacité aérobique des enfants du primaire. Méthodologie : des enfants de cinq à dix ans ont effectué le STEP selon un protocole qui incluait des marches de 0,1, 0,2 et 0,3 mètre (4, 8 et 12 pouces). Les participants ont effectué une épreuve d'effort sur tapis roulant avec spirométrie en circuit ouvert pour déterminer leur consommation maximale réelle d'oxygène (V̇o2max). Les chercheurs ont utilisé les coefficients de corrélation intraclasse (CCI) pour évaluer la fiabilité test-retest du STEP et des tests qui le composaient. Ils ont utilisé la régression linéaire multivariée pour évaluer les associations entre le STEP et le V̇o2max, rajustée pour tenir compte de covariances potentielles comme l'âge, le sexe, l'indice de masse corporelle (IMC) et le nombre de comorbidités. Résultats : le STEP était d'une excellente fiabilité (CCI ≥ 0,92; n = 170), quel que soit le niveau d'effort utilisé. Des problèmes relatifs à l'importance de l'effort et la colinéarité entre les variables indépendantes ont incité les chercheurs à exclure de l'analyse de régression les enfants de cinq et six ans (n = 45). Le modèle de régression final des enfants de sept à dix ans qui faisaient un effort approprié (n = 111), défini par un ratio d'échanges gazeux minimal de 1,0, a révélé que le STEP, le genre et l'IMC étaient très prédictifs du V̇o2max (R 2 = 0,51). Conclusion : ce nouveau test de la marche d'escalier qui n'est pas lié à l'effort peut évaluer la capacité aérobique des enfants de sept à dix ans. Les chercheurs ont fourni les équations de régression pour évaluer le V̇o2max à partir du STEP.

Reliability, validity, and minimal detectable change of the push-off test scores in assessing upper extremity weight-bearing ability.

STUDY DESIGN: Clinical measurement study. INTRODUCTION: The push-off test (POT) was recently conceived and found to be reliable and valid for assessing weight bearing through injured wrist or elbow. However, further research with larger sample can lend credence to the preliminary findings supporting the use of the POT. PURPOSE OF THE STUDY: This study examined the interrater reliability, construct validity, and measurement error for the POT in patients with wrist conditions. METHODS: Participants with musculoskeletal (MSK) wrist conditions were recruited. The performance on the POT, grip isometric strength of wrist extensors was assessed. The shortened version of the Disabilities of the Arm, Shoulder and Hand and numeric pain rating scale were completed. The intraclass correlation coefficient assessed interrater reliability of the POT. Pearson correlation coefficients (r) examined the concurrent relationships between the POT and other measures. The standard error of measurement and the minimal detectable change at 90% confidence interval were assessed as measurement error and index of true change for the POT. RESULTS: A total of 50 participants with different elbow or wrist conditions (age: 48.1 ± 16.6 years) were included in this study. The results of this study strongly supported the interrater reliability (intraclass correlation coefficient: 0.96 and 0.93 for the affected and unaffected sides, respectively) of the POT in patients with wrist MSK conditions. The POT showed convergent relationships with the grip strength on the injured side (r = 0.89) and the wrist extensor strength (r = 0.7). The POT showed smaller standard error of measurement (1.9 kg). The minimal detectable change at 90% confidence interval for the POT was 4.4 kg for the sample. CONCLUSIONS: This study provides additional evidence to support the reliability and validity of the POT. This is the first study that provides the values for the measurement error and true change on the POT scores in patients with wrist MSK conditions. Further research should examine the responsiveness and discriminant validity of the POT in patients with wrist conditions.

A systematic review of the benefits of occupation-based intervention for patients with upper extremity musculoskeletal disorders.

STUDY DESIGN: Systematic review of intervention studies (level 3a). INTRODUCTION: Occupation-based intervention (OBI) uses daily activities as a treatment modality. Its growing use with patients diagnosed with upper extremity musculoskeletal disorders (UE MSK) has driven interest in its supporting body of evidence. PURPOSE OF THE STUDY: The purpose of this study was to locate, appraise, and summarize current evidence of the effectiveness of OBI in treating patients with UE MSK. METHODS: Searches of PubMed, CINAHL, the Cochrane Register for Controlled Trials, and PEDro databases were conducted using predetermined keywords. Studies included in this systematic review described the use of OBI in UE MSK. Two examiners independently reviewed and assessed the quality of each study using the PEDro scale. RESULTS: Results of the database searches yielded 991 studies, 13 of which were deemed eligible to include in this review (6 randomized controlled trials, 4 pretreatment/post-treatment cohort or case series studies, and 3 single case reports). Quality of the studies varied, with 4 rated poor, 2 moderate, and 4 excellent. Overall, individuals receiving OBI showed superior benefits in patient-reported, performance, and physical measures assessing the upper extremity. DISCUSSION: Findings of this review provide preliminary evidence for the use of OBI with patients with UE MSK, however, generalizability of the evidence was compromised due to heterogeneity in study subjects as well as conceptualization, dosage, and delivery of OBI. CONCLUSIONS: The existing literature reflects promising trends in the use of OBI, underscoring its utility as a treatment option for UE MSK-related impairment, limitations, and restrictions. Nonetheless, scientific evidence concerning the effectiveness of OBI needs to be improved by conducting high-quality studies that clearly conceptualize this intervention and heighten understanding of its role in hand therapy practice.

Reliability, Concurrent Validity, and Minimal Detectable Change for iPhone Goniometer App in Assessing Knee Range of Motion.

Much of the published works assessing the reliability of smartphone goniometer apps (SG) have poor generalizability since the reliability was assessed in healthy subjects. No research has established the values for standard error of measurement (SEM) or minimal detectable change (MDC) which have greater clinical utility to contextualize the range of motion (ROM) assessed using the SG. This research examined the test-retest reproducibility, concurrent validity, SEM, and MDC values for the iPhone goniometer app (i-Goni; June Software Inc., v.1.1, San Francisco, CA) in assessing knee ROM in patients with knee osteoarthritis or those after total knee replacement. A total of 60 participants underwent data collection which included the assessment of active knee ROM using the i-Goni and the universal goniometer (UG; EZ Read Jamar Goniometer, Patterson Medical, Warrenville, IL), knee muscle strength, and assessment of pain and lower extremity disability using quadruple numeric pain rating scale (Q-NPRS) and lower extremity functional scale (LEFS), respectively. Intraclass correlation coefficients (ICCs) were calculated to assess the reproducibility of the knee ROM assessed using the i-Goni and UG. Bland and Altman technique examined the agreement between these knee ROM. The SEM and MDC values were calculated for i-Goni assessed knee ROM to characterize the error in a single score and the index of true change, respectively. Pearson correlation coefficient examined concurrent relationships between the i-Goni and other measures. The ICC values for the knee flexion/extension ROM were superior for i-Goni (0.97/0.94) compared with the UG (0.95/0.87). The SEM values were smaller for i-Goni assessed knee flexion/extension (2.72/1.18 degrees) compared with UG assessed knee flexion/extension (3.41/1.62 degrees). Similarly, the MDC values were smaller for both these ROM for the i-Goni (6.3 and 2.72 degrees) suggesting smaller change required to infer true change in knee ROM. The i-Goni assessed knee ROM showed expected concurrent relationships with UG, knee muscle strength, Q-NPRS, and the LEFS. In conclusion, the i-Goni demonstrated superior reproducibility with smaller measurement error compared with UG in assessing knee ROM in the recruited cohort. Future research can expand the inquiry for assessing the reliability of the i-Goni to other joints.

A structured literature synthesis of wrist outcome measures: An evidence-based approach to determine use among common wrist diagnoses.

STUDY DESIGN: Structured literature synthesis. INTRODUCTION: Hand therapists and researchers have numerous options when selecting outcome measures for patients with wrist pathologies. An evidence-based approach to determining which measures are used most often can inform choices. PURPOSE OF THE STUDY: To describe how frequently outcome measures are used in recent randomized controlled trials of patients with wrist diagnoses. Identifying assessment design and related International Classification of Functioning, Disability and Health (ICF) domains provides additional consideration for selection. METHODS: Systematic PubMed and Cumulative Index to Nursing and Allied Health Literature searches for the time frame between January 2005 and March 2015 captured measures used in randomized controlled trials researching wrist-specific fractures, ligament injuries, nerve injuries, arthritis/arthroplasty, or stress injuries/wrist pain. RESULTS: Three most frequent measures used within each diagnostic category are detailed with assessment design described and ICF domain identified. Across diagnoses, grip/pinch strength and Disabilities of Arm, Shoulder and Hand were the most frequently used physical and patient-reported outcome measures, respectively. The Jebsen-Taylor Hand Function Test was the most frequently used performance measure. DISCUSSION AND CONCLUSIONS: Consideration of the evidence, ICF domains, wrist diagnoses, and assessment design can help hand therapists select the measure most appropriate for use. LEVEL OF EVIDENCE: 2a.

Measurement Properties of the Lower Extremity Functional Scale: A Systematic Review.

STUDY DESIGN: Systematic review of measurement properties. BACKGROUND: Many primary studies have examined the measurement properties, such as reliability, validity, and sensitivity to change, of the Lower Extremity Functional Scale (LEFS) in different clinical populations. A systematic review summarizing these properties for the LEFS may provide an important resource. OBJECTIVE: To locate and synthesize evidence on the measurement properties of the LEFS and to discuss the clinical implications of the evidence. METHODS: A literature search was conducted in 4 databases (PubMed, MEDLINE, Embase, and CINAHL), using predefined search terms. Two reviewers performed a critical appraisal of the included studies using a standardized assessment form. RESULTS: A total of 27 studies were included in the review, of which 18 achieved a very good to excellent methodological quality level. The LEFS scores demonstrated excellent test-retest reliability (intraclass correlation coefficients ranging between 0.85 and 0.99) and demonstrated the expected relationships with measures assessing similar constructs (Pearson correlation coefficient values of greater than 0.7). The responsiveness of the LEFS scores was excellent, as suggested by consistently high effect sizes (greater than 0.8) in patients with different lower extremity conditions. Minimal detectable change at the 90% confidence level (MDC90) for the LEFS scores varied between 8.1 and 15.3 across different reassessment intervals in a wide range of patient populations. The pooled estimate of the MDC90 was 6 points and the minimal clinically important difference was 9 points in patients with lower extremity musculoskeletal conditions, which are indicative of true change and clinically meaningful change, respectively. CONCLUSION: The results of this review support the reliability, validity, and responsiveness of the LEFS scores for assessing functional impairment in a wide array of patient groups with lower extremity musculoskeletal conditions.

Primary Care Fall Risk Assessment for Elderly West Virginians.

West Virginia is ranked second nationally for the percent of its population 65 years of age. The elderly are especially susceptible to falls with fall risk increasing as age increases. Because falls are the number one cause of injury-related morbidity and mortality in the West Virginia elderly, evaluation of fall risk is a critical component of the patient evaluation in the primary care setting. We therefore highlight fall risk assessments that require no specialized equipment or training and can easily be completed at an established office visit. High quality clinical practice guidelines supported by the American Geriatric Society recommend yearly fall risk evaluation in the elderly. Those seniors at greatest risk of falls will benefit from the standardized therapy protocols outlined and referral to a balance treatment center. Patients with low-to-moderate fall risk attributed to muscle weakness or fatigue should be prescribed lower extremity strengthening exercises, such as kitchen counter exercises, to improve strength and balance.

A systematic review of the measurement properties of the patient-rated wrist evaluation.

STUDY DESIGN: Systematic review of measurement properties. OBJECTIVES: To summarize the measurement properties of the Patient-Rated Wrist Evaluation (PRWE) questionnaire. BACKGROUND: The PRWE is a region-specific outcome measure initially developed for assessing pain and function in individuals with distal radius fracture. However, subsequent research has expanded its use to other wrist/hand conditions. A systematic review of the measurement properties of the PRWE can enhance the understanding of its clinical applicability across different wrist/hand pathologies. METHODS: The MEDLINE, Embase, and CINAHL databases were searched using predefined search terms. A hand search of the bibliography of the primary studies was performed. Studies assessing at least 1 measurement property of the PRWE, either in the English version or versions in other languages, were included in this review. Two raters performed data extraction and critical appraisal of the primary studies using standardized instruments. RESULTS: A total of 22 primary studies met the inclusion criteria. The overall quality of the 22 studies ranged from 38% to 88%, with 9 scoring greater than 70%. Agreement between the raters who determined the quality of the studies was 0.75 (unweighted kappa). The measurement properties of the PRWE were summarized for different wrist/hand conditions. CONCLUSION: The PRWE is reliable, valid, and responsive across many wrist/hand conditions. Future studies should focus on determining values for the minimal detectable change and clinically important differences for the PRWE across different patient populations.

Baseline pain intensity is a predictor of chronic pain in individuals with distal radius fracture.

STUDY DESIGN: Secondary analysis of cohort study. OBJECTIVE: This study examined whether baseline pain intensity is a predictor of chronic pain and wrist/hand functions at 1 year following distal radius fracture (DRF). The study also examined the cutoff level for baseline pain intensity that best predicted chronic pain. BACKGROUND: Many individuals experience wrist/hand pain and functional impairments for as long as 1 year after DRF. Early identification of individuals at risk of these adverse outcomes can facilitate the delivery of required interventions to mitigate the risk. METHODS: Data for the Patient-Rated Wrist Evaluation (PRWE) pain and function subscales at baseline and 1 year after DRF, age, sex, injury to the dominant side, presence of comorbidity, education level, mechanism of fracture, smoking status, fall history, and energy of fracture were extracted from an existing data set. Multivariate regression analysis examined the utility of baseline pain intensity and the above variables in predicting pain and functional status at 1 year in individuals with DRF. Receiver operating characteristic curves examined the sensitivity/specificity of baseline pain intensity in predicting chronic pain and functional impairment. RESULTS: Required data were available for 386 individuals. Baseline pain intensity was found to be a strong predictor of chronic pain, explaining 22% of the variance. A baseline score of 35 out of 50 on the pain subscale of the PRWE had the best sensitivity (85%) and specificity (79%) cutoff values for predicting chronic pain at 1 year after DRF. CONCLUSION: Rehabilitation practitioners may be able to use a score of greater than 35/50 on the PRWE pain subscale to screen individuals at risk of chronic pain following DRF. LEVEL OF EVIDENCE: Prognosis, level 4.
