(Cost-)effectiveness of personalised multimodal physiotherapy compared to surgery in patients with cervical radiculopathy: A systematic review.

RATIONALE: Cervical radiculopathy is initially typically managed conservatively. Surgery is indicated when conservative management fails or with severe/progressive neurological signs. Personalised multimodal physiotherapy could be a promising conservative strategy. However, aggregated evidence on the (cost-)effectiveness of personalised multimodal physiotherapy compared to surgery with/without post-operative physiotherapy is lacking. AIM/OBJECTIVES: To systematically summarise the literature on the (cost-)effectiveness of personalised multimodal physiotherapy compared to surgery with or without post-operative physiotherapy in patients with cervical radiculopathy. METHODS: PubMed, Embase, CINAHL, PsycINFO and Web of Science were searched from inception to 1st of March 2023. Primary outcomes were effectiveness regarding costs, arm pain intensity and disability. Neck pain intensity, perceived recovery, quality of life, neurological symptoms, range-of-motion, return-to-work, medication use, (re)surgeries and adverse events were considered secondary outcomes. Randomised clinical trials comparing personalised multimodal physiotherapy versus surgical approaches with/without post-operative physiotherapy were included. Two independent reviewers performed study selection, data-extraction, and risk of bias assessment using the Cochrane RoB 2 and Consolidated Health Economic Evaluation Reporting Standards statement. Certainty of the evidence was determined using Grading of Recommendations, Assessment, Development and Evaluations. RESULTS: From 2109 records, eight papers from two original trials, with 117 participants in total were included. Low certainty evidence showed there were no significant differences on arm pain intensity and disability, except for the subscale 'heavy work' related disability (12 months) and disability at 5-8 years. Cost-effectiveness was not assessed. There was low certainty evidence that physiotherapy improved significantly less on neck pain intensity, sensory loss and perceived recovery compared to surgery with/without physiotherapy. Low certainty evidence showed there were no significant differences on numbness, range of motion, medication use, and quality of life. No adverse events were reported. CONCLUSION: Considering the clinical importance of accurate management recommendations and the current low level of certainty, high-quality cost-effectiveness studies are needed.

Pain exacerbation following physical activity in adults with diabetic neuropathy: Ecological momentary assessment of foot symptoms.

BACKGROUND AND OBJECTIVES: People with diabetic peripheral neuropathy (DPN) report fluctuating foot symptoms. This study used ecological momentary assessment to: (1) compare foot symptoms between days, time points and periods with/without preceding physical activity or pain medication; and (2) determine relationships between symptoms and endogenous pain modulation. METHOD: Ten low-active Australian adults with probable DPN underwent temporal summation of pain (TSP) and conditioned pain modulation (CPM) then completed mobile phone surveys five times daily for seven days, where they recorded the intensity of six foot symptoms and whether they performed physical activity or consumed pain medication in the preceding three hours.  RESULTS: All foot symptoms except numbness were greater in periods following physical activity, whereas periods following pain medication showed greater shooting pain. TSP showed very large correlations with sensitivity to touch, burning pain, shooting pain and prickling/tingling.  DISCUSSION: General practitioners should be aware that physical activity might exacerbate symptoms of DPN when encouraging their patients to be active.

Risk assessment of vascular complications following manual therapy and exercise for the cervical region: diagnostic accuracy of the International Federation of Orthopaedic Manipulative Physical Therapists framework (The Go4Safe project).

QUESTION: What is the diagnostic accuracy of the International Federation of Orthopaedic Manipulative Physical Therapists (IFOMPT) framework to assess the risk of vascular complications in patients seeking physiotherapy care for neck pain and/or headache? DESIGN: Cross-sectional diagnostic accuracy study. PARTICIPANTS: One hundred and fifty patients seeking physiotherapy for neck pain and/or headache in primary care. METHODS: Nineteen physiotherapists performed the index test according to the IFOMPT framework. Patients were classified as having a high, intermediate or low risk of vascular complications, following manual therapy and/or exercise, derived from the estimated risk of the presence of vascular pathology. The reference test was a consensus medical decision reached by a vascular neurologist and an interventional neurologist, with input from a neuroradiologist. The neurologists had access to clinical data and magnetic resonance imaging of the cervical spine, including an angiogram of the cervical arteries. OUTCOME MEASURES: Diagnostic accuracy measures were calculated for 'no contraindication' (ie, the low-risk category) and 'contraindication' (ie, the high-risk and intermediate-risk categories) for manual therapy and/or exercise. Sensitivity, specificity, predictive values, likelihood ratios and the area under the curve were calculated. RESULTS: Manual therapy and/or exercise were contraindicated in 54.7% of the patients. The sensitivity of the IFOMPT framework was low (0.50, 95% CI 0.39 to 0.61) and its specificity was moderate (0.63, 95% CI 0.51 to 0.75). The positive and negative likelihood ratios were weak at 1.36 (95% CI 0.93 to 1.99) and 0.79 (95% CI 0.60 to 1.05), respectively. The area under the curve was poor (0.57, 95% CI 0.49 to 0.65). CONCLUSION: The IFOMPT framework has poor diagnostic accuracy when compared with a reference standard consisting of a consensus medical decision.

Implementing PainChek and PARO to Support Pain Assessment and Management in Residents with Dementia: A Qualitative Study.

BACKGROUND: Pain is a common problem but often undiagnosed and untreated in people with dementia. AIMS: This study explored the experiences of residents with dementia, family, andformal carers with (1) pain assessment and management for residents with dementia; (2) the use of the PainChek app for pain assessment, and (3) the use of a social robot PARO for pain management in residents with dementia. DESIGN: A qualitative study. SETTINGS/PARTICIPANTS: Interviews were conducted with 13 residents withdementia, three family members, and 18 formal carers from a residential aged carefacility. METHOD: Residents with dementia interacted with PARO for 15 mins, five days perweek for three weeks. The PainChek app assessed pain levels before and after eachsession. After three-week intervention, individual interviews were conducted withresidents, family, and formal carers who experienced or observed the use of PainChekapp and PARO for residents. Interviews were audio-recorded, transcribed, andanalyzed using thematic analysis. RESULTS: Four themes were identified regarding pain in residents with dementia: (1) the impact, challenges and strategies of pain assessment and management; (2) benefits and barriers of using PainChek app to assess pain; (3) benefits of interacting with PARO to manage pain and behavioral symptoms; and (4) implementing PainChek app and PARO to support pain assessment and management in dementia care. CONCLUSIONS: Technology, such as PainChek and PARO, is promising to improve painassessment and reduce pain for people with dementia. Barriers to using technologyinclude limited staff training and the implementation of person-centered care.

Reliability and validity of assessment methods available in primary care for bladder outlet obstruction and benign prostatic obstruction in men with lower urinary tract symptoms: a systematic review.

OBJECTIVES: To systematically review the literature regarding the reliability and validity of assessment methods available in primary care for bladder outlet obstruction or benign prostatic obstruction in men with lower urinary tract symptoms (LUTS). DESIGN: Systematic review with best evidence synthesis. SETTING: Primary care. PARTICIPANTS: Men with LUTS due to bladder outlet obstruction or benign prostatic obstruction. REVIEW METHODS: PubMed, Ebsco/CINAHL and Embase databases were searched for studies on the validity and reliability of assessment methods for bladder outlet obstruction and benign prostatic obstruction in primary care. Methodological quality was assessed with the COSMIN checklist. Studies with poor methodology were excluded from the best evidence synthesis. RESULTS: Of the 5644 studies identified, 61 were scored with the COSMIN checklist, 37 studies were included in the best evidence synthesis, 18 evaluated bladder outlet obstruction and 17 benign prostatic obstruction, 2 evaluated both. Overall, reliability was poorly evaluated. Transrectal and transabdominal ultrasound showed moderate to good validity to evaluate bladder outlet obstruction. Measured prostate volume with these ultrasound methods, to identify benign prostatic obstruction, showed moderate to good accuracy, supported by a moderate to high level of evidence. Uroflowmetry for bladder outlet obstruction showed poor to moderate diagnostic accuracy, depending on used cut-off values. Questionnaires were supported by high-quality evidence, although correlations and diagnostic accuracy were poor to moderate compared with criterion tests. Other methods were supported by low level evidence. CONCLUSION: Clinicians in primary care can incorporate transabdominal and transrectal ultrasound or uroflowmetry in the evaluation of men with LUTS but should not solely rely on these methods as the diagnostic accuracy is insufficient and reliability remains insufficiently researched. Low-to-moderate levels of evidence for most assessment methods were due to methodological shortcomings and inconsistency in the studies. This highlights the need for better study designs in this domain.

Modernising tactile acuity assessment; clinimetrics of semi-automated tests and effects of age, sex and anthropometry on performance.

BACKGROUND: Reduced tactile acuity has been observed in several chronic pain conditions and has been proposed as a clinical indicator of somatosensory impairments related to the condition. As some interventions targeting these impairments have resulted in pain reduction, assessing tactile acuity may have significant clinical potential. While two-point discrimination threshold (TPDT) is a popular method of assessing tactile acuity, large measurement error has been observed (impeding responsiveness) and its validity has been questioned. The recently developed semi-automated 'imprint Tactile Acuity Device' (iTAD) may improve tactile acuity assessment, but clinimetric properties of its scores (accuracy score, response time and rate correct score) need further examination. AIMS: Experiment 1: To determine inter-rater reliability and measurement error of TPDT and iTAD assessments. Experiment 2: To determine internal consistencies and floor or ceiling effects of iTAD scores, and investigate effects of age, sex, and anthropometry on performance. METHODS: Experiment 1: To assess inter-rater reliability (ICC(2,1)) and measurement error (coefficient of variation (CoV)), three assessors each performed TPDT and iTAD assessments at the neck in forty healthy participants. Experiment 2: To assess internal consistency (ICC(2,k)) and floor or ceiling effects (skewness z-scores), one hundred healthy participants performed the iTAD's localisation and orientation tests. Balanced for sex, participants were equally divided over five age brackets (18-30, 31-40, 41-50, 51-60 and 61-70). Age, sex, body mass index (BMI) and neck surface area were assessed to examine their direct (using multiple linear regression analysis) and indirect (using sequential mediation analysis) relationship with iTAD scores. RESULTS: Mean ICC(2,1) was moderate for TPDT (0.70) and moderate-to-good for the various iTAD scores (0.65-0.86). The CoV was 25.3% for TPDT and ranged from 6.1% to 16.5% for iTAD scores. Internal consistency was high for both iTAD accuracy scores (ICC(2,6) = 0.84; ICC(2,4) = 0.86). No overt floor or ceiling effects were detected (all skewness z-scores < 3.29). Accuracy scores were only directly related to age (decreasing with increasing age) and sex (higher for men). DISCUSSION: Although reliability was similar, iTAD scores demonstrated less measurement error than TPDT indicating a potential for better responsiveness to treatment effects. Further, unlike previously reported for TPDT, iTAD scores appeared independent of anthropometry, which simplifies interpretation. Additionally, the iTAD assesses multiple aspects of tactile processing which may provide a more comprehensive evaluation of tactile acuity. Taken together, the iTAD shows promise in measuring tactile acuity, but patient studies are needed to verify clinical relevance.

Health-care providers' perspectives on factors influencing return-to-work after surgery for nontraumatic conditions of the upper extremity.

STUDY DESIGN: This study is a descriptive survey. INTRODUCTION: Health care providers (HCPs) are key stakeholders who facilitate workers' return to work (RTW) following upper extremity surgery. Hand therapists play a major role in this process, yet we do not know if and/or how their perspectives differ from other HCPs. PURPOSE OF THE STUDY: This study examined HCPs' opinion on factors that influence RTW after surgery for nontraumatic upper extremity conditions and whether HCPs from different disciplines differed in their opinion. METHODS: HCPs (occupational therapists, physiotherapists, hand therapists, exercise physiologists, psychologists, surgeons, and general practitioners) completed a survey rating 50 factors on a worker's ability to RTW. Each factor was scored using a 5-point Likert scale from "not" to "extremely" influential, which was later dichotomised. Agreement was indicated at 75%. The level of disagreement between disciplines was examined. RESULTS: Respondents (n = 787) identified 20 factors being influential on RTW. They are (in order from highest to lowest) poor pain coping (the highest, >85% of respondents), postoperative psychological state, RTW self-efficacy, employer/supervisor's support, employer's unwillingness for job modification, recovery expectations, job satisfaction, suitable duties availability, whether the job can be modified, and mood disorder diagnosis. There was agreement that two factors do not influence RTW, gender, and preemployment medical assessment. There was disagreement (P < .05) between HCP disciplines on six factors (obesity, comorbidities, doctors' RTW recommendation, diagnosis, fitness, income). There were no consistent patterns with respect to which professions disagreed across all six factors. Hand therapists differed from the other disciplines for three of the factors including diagnosis, comorbidities, and doctor's recommendation for RTW. DISCUSSION: The factors that stakeholders agreed as having the greatest influence were mainly related to the worker (pain and psychological factors) and the workplace and are amenable to RTW interventions. CONCLUSION: Interventions facilitating RTW and future research should consider the factors identified by HCPs in this study.

Perspectives from Employers, Insurers, Lawyers and Healthcare Providers on Factors that Influence Workers' Return-to-Work Following Surgery for Non-Traumatic Upper Extremity Conditions.

PURPOSE: Return-to-work (RTW) stakeholders have varied roles and may therefore hold their own perspectives regarding factors that may influence outcomes. This study aimed to determine stakeholders' perspectives on factors influencing RTW following surgery for non-traumatic upper extremity conditions. METHODS: A questionnaire was distributed to RTW stakeholders via gatekeeper organizations. Stakeholders rated 50 potential prognostic factors from 'not' to 'extremely' influential. Data were dichotomized to establish stakeholders' level of agreement. Disagreements between stakeholder groups were analyzed using χ 2. The relationship between stakeholder demographic variables and rating of a factor was determined via regression analysis. RESULTS: One thousand and eleven stakeholders completed the survey: healthcare providers (77.8 %); employer representatives (12.2 %); insurer representatives (6.8 %); and lawyers (3.2 %). Factors with the highest stakeholder agreement for influencing RTW were: self-efficacy (92.2 %); post-operative psychological status (91.8 %); supportive employer/supervisor (91.4 %); employer's willingness to accommodate job modifications (90.7 %); worker's recovery expectations (88.3 %); mood disorder diagnosis (86.6 %); post-operative pain level (86.4 %); and whether the job can be modified (86.3 %). Disagreements between stakeholder groups were found for 19 (36 %) factors. The strongest disagreements were for: age; gender; obesity; doctor's RTW recommendation; and presence of a RTW coordinator. Respondents' characteristics (e.g., age, workers' compensation jurisdiction, work experience, stakeholder group) were associated with factor rating. CONCLUSION: The factors stakeholders rated as having the greatest influence on RTW were predominately psychosocial and modifiable. These variables should be the focus of future research to determine prognostic factors for RTW for workers with upper extremity conditions, and to develop effective RTW interventions.

Non-invasive assessment of sciatic nerve stiffness during human ankle motion using ultrasound shear wave elastography.

Peripheral nerves are exposed to mechanical stress during movement. However the in vivo mechanical properties of nerves remain largely unexplored. The primary aim of this study was to characterize the effect of passive dorsiflexion on sciatic nerve shear wave velocity (an index of stiffness) when the knee was in 90° flexion (knee 90°) or extended (knee 180°). The secondary aim was to determine the effect of five repeated dorsiflexions on the nerve shear wave velocity. Nine healthy participants were tested. The repeatability of sciatic nerve shear wave velocity was good for both knee 90° and knee 180° (ICCs ≥ 0.92, CVs ≤ 8.1%). The shear wave velocity of the sciatic nerve significantly increased (p<0.0001) during dorsiflexion when the knee was extended (knee 180°), but no changes were observed when the knee was flexed (90°). The shear wave velocity-angle relationship displayed a hysteresis for knee 180°. Although there was a tendency for the nerve shear wave velocity to decrease throughout the repetition of the five ankle dorsiflexions, the level of significance was not reached (p=0.055). These results demonstrate that the sciatic nerve stiffness can be non-invasively assessed during passive movements. In addition, the results highlight the importance of considering both the knee and the ankle position for clinical and biomechanical assessment of the sciatic nerve. This non-invasive technique offers new perspectives to provide new insights into nerve mechanics in both healthy and clinical populations (e.g., specific peripheral neuropathies).
