Cost-Effectiveness Evaluation of Manual Physical Therapy Versus Surgery for Carpal Tunnel Syndrome: Evidence From a Randomized Clinical Trial

External wrist ratio is not a proxy for internal carpal tunnel shape: Implications for evaluating carpal tunnel syndrome risk

Carpal tunnel syndrome (CTS) is highly prevalent, resulting in decreased function and increased need for costly healthcare services. External wrist ratio (depth/width >0.70) is a strong predictor of the development of CTS and has been suggested to be a proxy for internal carpal tunnel (CT) shape. Conversely, sonography can more directly evaluate CT shape. The purpose of our study was to explore the relationship between wrist ratio and sonographic CT measurements to (1) evaluate the reliability of sonographic CT measurements and (2) explore how external wrist measures relate to anthropometric features of the CT. We used sonographic imaging on a sample of healthy participants (n = 226) to measure CT cross-sectional area, depth, width, and depth/width ratio. We conducted exploratory correlation and regression analyses to identify relationships of these measures with external wrist ratio. Reliability for dominant and nondominant sonographic CT measures ranged from good to excellent (0.79-0.95). Despite a moderate correlation between CT width and depth and their external wrist counterparts (0.33-0.41, p < 0.001), wrist ratio and CT ratio demonstrated weak to no correlation (dominant: r = 0.12, p = 0.053; nondominant: r = 0.20, p = 0.002) and the mean CT ratio was far lower than the mean wrist ratio (0.45 vs. 0.71 bilaterally). Supporting this, we observed several key differences in the relationship between external wrist measures compared to corresponding CT measures. Additionally, regression analyses combining participant factors and CT measurements produced models accounting for less than 15% of the variability in external wrist ratio (linear models) or correctly predicting less than 68% of wrist ratio-based risk categorization (logistic models). Overall, among healthy young adults, wrist shape is not an adequate proxy for CT shape.

How Does Nerve Mechanical Interface Treatment Impact Pre-Surgical Carpal Tunnel Syndrome Patients? A Randomized Controlled Trial

BACKGROUND

Carpal tunnel syndrome (CTS) presents a high burden on the healthcare system. However, no alternative treatments are provided during the waiting period. In addition, the incidence of severe patients with comorbidities is underestimated. The aim of this study was to determine whether nerve mechanical interface treatment improves the symptoms, function, and quality of life in pre-surgical CTS patients.

METHODS

A randomized controlled trial and intention-to-treat analysis were carried out. Forty-two patients with an electrodiagnosis of carpal tunnel syndrome, included on the surgery waiting list of a public healthcare system, were analyzed. The intervention group (n = 20) received a 45 min session/per week of instrument-assisted manual therapy (diacutaneous fibrolysis) for 3 weeks. The Boston Carpal Tunnel Questionnaire (BCTQ) was the primary outcome. The symptoms, mechanical threshold, grip strength, mechanosensitivity of the median nerve, quality of life, and patient satisfaction were included as secondary outcomes. The control group (n = 22) remained on the waiting list.

RESULTS

The intervention seems to be beneficial for the BCTQ score (function and symptoms scale), pain, and mechanosensitivity after treatment, at the 3 and 6 months follow-up (p < 0.05). Kinesiophobia was improved at 6 months (p = 0.043; η2 = 0.10) and the mechanical threshold at the 3-month follow-up (p = 0.048; η2 = 0.10). No differences were identified for grip strength. At 6 months, the intervention group patients were satisfied (100%), as opposed to the controls, who felt that they had experienced a worsening of their condition (50.1%).

CONCLUSIONS

Nerve mechanical interface treatment improved the symptoms, function, and quality of life in pre-surgical CTS patients. One hundred percent of the treated patients, characterized as moderate and severe CTS with associated comorbidities, were satisfied.

Cost-Effectiveness of Treatments for Musculoskeletal Conditions Offered by Physiotherapists: A Systematic Review of Trial-Based Evaluations

BACKGROUND

Musculoskeletal conditions are a leading contributor to disability worldwide. The treatment of these conditions accounts for 7% of health care costs in Germany and is often provided by physiotherapists. Yet, an overview of the cost-effectiveness of treatments for musculoskeletal conditions offered by physiotherapists is missing. This review aims to provide an overview of full economic evaluations of interventions for musculoskeletal conditions offered by physiotherapists.

METHODS

We systematically searched for publications in Medline, EconLit, and NHS-EED. Title and abstracts, followed by full texts were screened independently by two authors. We included trial-based full economic evaluations of physiotherapeutic interventions for patients with musculoskeletal conditions and allowed any control group. We extracted participants' information, the setting, the intervention, and details on the economic analyses. We evaluated the quality of the included articles with the Consensus on Health Economic Criteria checklist.

RESULTS

We identified 5141 eligible publications and included 83 articles. The articles were based on 78 clinical trials. They addressed conditions of the spine (n = 39), the upper limb (n = 8), the lower limb (n = 30), and some other conditions (n = 6). The most investigated conditions were low back pain (n = 25) and knee and hip osteoarthritis (n = 16). The articles involved 69 comparisons between physiotherapeutic interventions (in which we defined primary interventions) and 81 comparisons in which only one intervention was offered by a physiotherapist. Physiotherapeutic interventions compared to those provided by other health professionals were cheaper and more effective in 43% (18/42) of the comparisons. Ten percent (4/42) of the interventions were dominated. The overall quality of the articles was high. However, the description of delivered interventions varied widely and often lacked details. This limited fair treatment comparisons.

CONCLUSIONS

High-quality evidence was found for physiotherapeutic interventions to be cost-effective, but the result depends on the patient group, intervention, and control arm. Treatments of knee and back conditions were primarily investigated, highlighting a need for physiotherapeutic cost-effectiveness analyses of less often investigated joints and conditions. The documentation of provided interventions needs improvement to enable clinicians and stakeholders to fairly compare interventions and ultimately adopt cost-effective treatments.

Demographic and Diagnostic Factors in Physical Therapy Attendance

Introduction Physical therapy (PT) is an effective nonoperative treatment for various orthopedic diagnoses. However, patients may have many reasons to dismiss PT, including favoring another intervention for their injury, time constraints, transportation, and cost. This dismissal of PT may contribute to inadequate patient compliance. This study aimed to elucidate patient compliance with a basic PT prescription and whether PT led to subjective injury improvement. Methods This is a retrospective study of patients observed in Stony Brook Orthopedic clinics from 08/01/2022 to 12/23/2022. Patients prescribed PT received a phone call six weeks after the PT prescription. The primary outcome was patient attendance at PT. Secondary outcomes were subjective; symptomatic improvement was listed as better, worse, or the same. Chi-square testing was used to compare outcomes. Results A total of 100 patients were enrolled in the study. Patients prescribed PT following surgery were more likely to attend compared to patients prescribed PT as a primary treatment (P value=0.027). The association between attendance at PT and a change in subjective symptoms (better, worse, same) was not significant. Patients' age, sex, and chronicity of injury were not significant factors in PT attendance. Of the 40 patients who did not attend PT, 14 cited time constraints, 11 utilized self-directed treatment, three cited insurance, two cited transportation, and 10 cited other reasons. Conclusions Overall, postoperative patients were more likely to attend PT compared to patients prescribed PT as a primary treatment. Factors such as age, sex, and chronicity of injury did not affect whether a patient attended PT. Of the patients enrolled, 71% stated subjective improvement in symptoms, but there was no association between symptoms and PT attendance. This study highlights the characteristics of those patient factors that may influence PT compliance and underscores the importance of further research into the population most likely to attend and benefit from PT.

Surgical versus non-surgical treatment for carpal tunnel syndrome

BACKGROUND

Carpal tunnel syndrome (CTS) is a compression neuropathy of the median nerve at the wrist. Surgery is considered when symptoms persist despite the use of non-surgical treatments. It is unclear whether surgery produces a better outcome than non-surgical therapy. This is an update of a Cochrane review published in 2008.

OBJECTIVES

To assess the evidence regarding the benefits and harms of carpal tunnel release compared with non-surgical treatment in the short (< 3 months) and long (> 3 months) term.

SEARCH METHODS

In this update, we included studies from the previous version of this review and searched the Cochrane Neuromuscular Specialised Register, CENTRAL, Embase, MEDLINE, ClinicalTrials.gov and WHO ICTRP until 18 November 2022. We also checked the reference lists of included studies and relevant systematic reviews for studies.

SELECTION CRITERIA

We included randomised controlled trials comparing any surgical technique with any non-surgical therapies for CTS.

DATA COLLECTION AND ANALYSIS

We used the standard methodological procedures expected by Cochrane.

MAIN RESULTS

The 14 included studies randomised 1231 participants (1293 wrists). Eighty-four per cent of participants were women. The mean age ranged from 32 to 53 years, and the mean duration of symptoms from 31 weeks to 3.5 years. Trial sizes varied from 22 to 176 participants. The studies compared surgery with: splinting, corticosteroid injection, splinting and corticosteroid injection, platelet-rich plasma injection, manual therapy, multimodal non-operative treatment, unspecified medical treatment and hand support, and surgery and corticosteroid injection with corticosteroid injection alone. Since surgery is generally used for its long-term effects, this abstract presents only long-term results for surgery versus splinting and surgery versus corticosteroid injection. 1) Surgery compared to splinting in the long term (> 3 months) Surgery probably results in a higher rate of clinical improvement (risk ratio (RR) 2.10, 95% confidence interval (CI) 1.04 to 4.24; 3 studies, 210 participants; moderate-certainty evidence). Surgery probably does not provide clinically important benefit in symptoms or hand function compared with splinting (moderate-certainty evidence). The mean Boston Carpal Tunnel Questionnaire (BCTQ) Symptom Severity Scale (scale 1 to 5; higher is worse; minimal clinically important difference (MCID) = 1) was 1.54 with splint and 0.26 points better with surgery (95% CI 0.52 better to 0.01 worse; 2 studies, 195 participants). The mean BCTQ Functional Status Scale (scale 1 to 5; higher is worse; MCID 0.7) was 1.75 with splint and 0.36 points better with surgery (95% CI 0.62 better to 0.09 better; 2 studies, 195 participants). None of the studies reported pain. Surgery may not provide better health-related quality of life compared with splinting (low-certainty evidence). The mean EQ-5D index (scale 0 to 1; higher is better; MCID 0.074) was 0.81 with splinting and 0.04 points better with surgery (95% CI 0.0 to 0.08 better; 1 study, 167 participants). We are uncertain about the risk of adverse effects (very low-certainty evidence). Adverse effects were reported amongst 60 of 98 participants (61%) in the surgery group and 46 of 112 participants (41%) in the splinting group (RR 2.11, 95% CI 0.37 to 12.12; 2 studies, 210 participants). Surgery probably reduces the risk of further surgery; 41 of 93 participants (44%) were referred to surgery in the splinting group and 0 of 83 participants (0%) repeated surgery in the surgery group (RR 0.03, 95% CI 0.00 to 0.21; 2 studies, 176 participants). This corresponds to a number needed to treat for an additional beneficial outcome (NNTB) of 2 (95% CI 1 to 9). 2) Surgery compared to corticosteroid injection in the long term (> 3 months) We are uncertain if clinical improvement or symptom relief differs between surgery and corticosteroid injection (very low-certainty evidence). The RR for clinical improvement was 1.23 (95% CI 0.73 to 2.06; 3 studies, 187 participants). For symptoms, the standardised mean difference (SMD) was -0.60 (95% CI -1.88 to 0.69; 2 studies, 118 participants). This translates to 0.4 points better (95% CI from 1.3 better to 0.5 worse) on the BCTQ Symptom Severity Scale. Hand function or pain probably do not differ between surgery and corticosteroid injection (moderate-certainty evidence). For function, the SMD was -0.12 (95% CI -0.80 to 0.56; 2 studies, 191 participants) translating to 0.10 points better (95% CI 0.66 better to 0.46 worse) on the BCTQ Functional Status Scale with surgery. Pain (0 to 100 scale) was 8 points with corticosteroid injection and 6 points better (95% CI 10.45 better to 1.55 better; 1 study, 123 participants) with surgery. We found no data to estimate the difference in health-related quality of life (very low-certainty evidence). We are uncertain about the risk of adverse effects and further surgery (very low-certainty evidence). Adverse effects were reported amongst 3 of 45 participants (7%) in the surgery group and 2 of 45 participants (4%) in the corticosteroid injection group (RR 1.49, 95% CI 0.25 to 8.70; 2 studies, 90 participants). In one study, 12 of 83 participants (15%) needed surgery in the corticosteroid group, and 7 of 80 participants (9%) needed repeated surgery in the surgery group (RR 0.61, 95% CI 0.25 to 1.46; 1 study, 163 participants).

AUTHORS' CONCLUSIONS

Currently, the efficacy of surgery in people with CTS is unclear. It is also unclear if the results can be applied to people who are not satisfied after trying various non-surgical options. Future studies should preferably blind participants from treatment allocation and randomise people who are dissatisfied after being treated non-surgically. The decision for a patient to opt for surgery should balance the small benefits and potential risks of surgery. Patients with severe symptoms, a high preference for clinical improvement and reluctance to adhere to non-surgical options, and who do not consider potential surgical risks and morbidity a burden, may choose surgery. On the other hand, those who have tolerable symptoms, who have not tried non-surgical options and who want to avoid surgery-related morbidity can start with non-surgical options and have surgery only if necessary. We are uncertain if the risk of adverse effects differs between surgery and non-surgical treatments. The severity of adverse effects may also be different.

Platelet-Rich Plasma Versus Corticosteroid Injections for the Treatment of Mild-to-Moderate Carpal Tunnel Syndrome: A Markov Cost-Effectiveness Decision Analysis

BACKGROUND

Platelet-rich plasma (PRP) or corticosteroid injections may be used to conservatively treat mild-to-moderate carpal tunnel syndrome (CTS). We evaluated the cost-effectiveness of PRP injections versus corticosteroid injections for the treatment of mild-to-moderate CTS.

METHODS

Markov modeling was used to analyze the base-case 45-year-old patient with mild-to-moderate CTS, unresponsive to conservative treatments, never previously treated with an injection or surgery, treated with a single injection of PRP, or methylprednisolone/triamcinolone 40 mg/mL. Transition probabilities were derived from level-I/II studies, utility values from the Tufts University Cost-Effectiveness Analysis Registry reported using visual analog scale (VAS), Boston Carpal Tunnel Questionnaire Symptom severity (BCTQ-S), and Boston Carpal Tunnel Questionnaire Functional status (BCTQ-F), and costs from Medicare, published studies, and industry. Analyses were performed from healthcare/societal perspectives. Outcomes were incremental cost-effectiveness ratios (ICER) and net monetary benefits (NMB). Willingness-to-pay thresholds were $50 000 and $100 000. Deterministic/probabilistic sensitivity analyses were performed.

RESULTS

From a healthcare perspective, compared to PRP injections, the ICER for corticosteroid injections measured by VAS: -$13.52/quality-adjusted-life-years (QALY), BCTQ-S: -$11.88/QALY, and BCTQ-F: -$16.04/QALY. PRP versus corticosteroid injections provided a NMB measured by VAS: $428 941.12 versus $375 788.21, BCTQ-S: $417 115.09 versus $356 614.18, and BCTQ-F: $421 706.44 versus $376 908.45. From a societal perspective, compared to PRP injections, the ICER for corticosteroid injections measured by VAS: -$1024.40/QALY, BCTQ-S: -$899.95/QALY, and BCTQ-F: -$1215.51/QALY. PRP versus corticosteroid injections provided a NMB measured by VAS: $428 171.63 versus $373 944.39, BCTQ-S: $416 345.61 versus $354 770.36, and BCTQ-F: $420 936.95 versus $375 064.63.

CONCLUSIONS

PRP injections were more cost-effective than methylprednisolone/triamcinolone injections from healthcare and societal perspectives for mild-to-moderate CTS.

Neurodynamic Techniques in the Treatment of Mild-to-Moderate Carpal Tunnel Syndrome: A Systematic Review and Meta-Analysis

Carpal tunnel syndrome (CTS) is a condition that affects the main nerves in the wrist area that causes numbness, tingling, and weakness in the hand and arm. CTS affects 5% of the general population and results in pain in the wrist due to repetitive use, most commonly affecting women and office workers. Conservative management of CTS includes neurodynamic modulation to promote median nerve gliding during upper limb movements to maintain normal function. However, evidence for the benefits of neurodynamic modulation found disparities, and hence, the effectiveness of neurodynamic modulation remains unclear. This study aimed to systematically review the current evidence from randomized controlled trials (RCTs) to establish the effectiveness of neurodynamic techniques as a non-surgical treatment option for CTS. Using the PRISMA guidelines, two authors searched four electronic databases, and studies were included if they conformed to pre-established eligibility criteria. Primary outcome measures included outcomes from the Boston carpal tunnel syndrome questionnaire, while secondary outcomes included nerve conduction velocity, pain, and grip strength. Quality assessment was completed using the Cochrane RoB2 form, and a meta-analysis was performed to assess heterogeneity. Twelve RCTs met our inclusion/exclusion criteria with assessments on 1003 participants in the treatment and control arms. High heterogeneity and some risks of bias were observed between studies, but the results of the meta-analysis showed a significant reduction in our primary outcome, the Boston carpal tunnel syndrome questionnaire-symptom severity scale (mean difference = -1.20, 95% CI [-1.72, -0.67], p < 0.00001) and the Boston carpal tunnel syndrome questionnaire-functional severity scale (mean difference = -1.06, 95% CI [-1.53, -0.60], p < 0.00001). Secondary outcomes such as sensory and motor conduction velocity increased significantly, while motor latency was significantly reduced, all positively favoring neurodynamic techniques. Pain was also significantly reduced, but grip strength was not significantly different. Our systematic review demonstrates significant benefits of neurodynamic modulation techniques to treat CTS and specifically that it reduces symptom severity, pain, and motor latency, while at the same time improving nerve conduction velocities. Hence, our study demonstrates a clear benefit of neurodynamic techniques to improve recovery CTS.

Patient-Centred Outcomes Following Open Carpal Tunnel Release: A Systematic Review of the Current Literature

Background: Patients’ individual interpretations of their own health outcomes are becoming increasingly important metrics in defining clinical success across all specialties, especially in hand surgery. However, there is a relative paucity of data using validated health-related quality of life (HR-QoL) assessments for carpal tunnel release (CTR). The purpose of this study was to review published outcomes on traditional open CTR to formally assess the current need for more accurate, validated assessment tools to evaluate CTR-specific HR-QoL.

Methods: PubMed, MEDLINE and Cochrane Library databases were queried according to PRISMA guidelines for all studies investigating patient-reported outcomes following traditional open CTR. Analysis focused on HR-QoL, symptomatic relief, functional status, overall satisfaction and return to work or activities of daily living (ADLs).

Results: In total, 588 unique articles were screened, and 30 studies met selection criteria. HR-QoL was formally assessed in only 3 studies using the validated 36-Item Short Form Survey. Symptomatic relief was measured in 29 (97%) studies, making it the most frequently reported item, whereas functional ability was reported by 19 (63%) studies. The Boston Carpal Tunnel Questionnaire was the most frequently utilised tool to assess symptomatic relief (13/30) and functional improvement (11/30). Using unvalidated custom surveys, 14 studies (47%) reported patient satisfaction and 12 studies (40%) documented time to return to work/ADLs.

Conclusion: There is a dearth of studies utilising HR-QoL assessment tools to evaluate outcomes following traditional open CTR. The creation and validation of new CTR-specific HR-QoL tools accounting for both physical and psychological health is warranted.

Level of Evidence: Level II (Therapeutic)

Do Short-Term Effects Predict Long-Term Improvements in Women Who Receive Manual Therapy or Surgery for Carpal Tunnel Syndrome? A Bayesian Network Analysis of a Randomized Clinical Trial

OBJECTIVE

The purpose of this study was to develop a data-driven Bayesian network approach to understand the potential multivariate pathways of the effect of manual physical therapy in women with carpal tunnel syndrome (CTS).

METHODS

Data from a randomized clinical trial (n = 104) were analyzed comparing manual therapy including desensitization maneuvers of the central nervous system versus surgery in women with CTS. All variables included in the original trial were included in a Bayesian network to explore its multivariate relationship. The model was used to quantify the direct and indirect pathways of the effect of physical therapy and surgery on short-term, mid-term, and long-term changes in the clinical variables of pain, related function, and symptom severity.

RESULTS

Manual physical therapy improved function in women with CTS (between-groups difference: 0.09; 95% CI = 0.07 to 0.11). The Bayesian network showed that early improvements (at 1 month) in function and symptom severity led to long-term (at 12 months) changes in related disability both directly and via complex pathways involving baseline pain intensity and depression levels. Additionally, women with moderate CTS had 0.14-point (95% CI = 0.11 to 0.17 point) poorer function at 12 months than those with mild CTS and 0.12-point (95% CI = 0.09 to 0.15 point) poorer function at 12 months than those with severe CTS.

CONCLUSION

Current findings suggest that short-term benefits in function and symptom severity observed after manual therapy/surgery were associated with long-term improvements in function, but mechanisms driving these effects interact with depression levels and severity as assessed using electromyography. Nevertheless, it should be noted that between-group differences depending on severity determined using electromyography were small, and the clinical relevance is elusive. Further data-driven analyses involving a broad range of biopsychosocial variables are recommended to fully understand the pathways underpinning CTS treatment effects.

IMPACT

Short-term effects of physical manual therapy seem to be clinically relevant for obtaining long-term effects in women with CTS.

Methodologic and Reporting Quality of Economic Evaluations in Hand and Wrist Surgery: A Systematic Review

BACKGROUND

Economic evaluations can inform decision-making; however, previous publications have identified poor quality of economic evaluations in surgical specialties.

METHODS

Study periods were from January 1, 2006, to April 20, 2020 (methodologic quality) and January 1, 2014, to April 20, 2020 (reporting quality). Primary outcomes were methodologic quality [Guidelines for Authors and Peer Reviewers of Economic Submissions to The BMJ (Drummond's checklist), 33 points; Quality of Health Economic Studies (QHES), 100 points; Consensus on Health Economic Criteria (CHEC), 19 points] and reporting quality (Consolidated Health Economic Evaluation Standards (CHEERS) statement, 24 points).

RESULTS

Forty-seven hand economic evaluations were included. Partial economic analyses (i.e., cost analysis) were the most common (n = 34; 72 percent). Average scores of full economic evaluations (i.e., cost-utility analysis and cost-effectiveness analysis) were: Drummond's checklist, 27.08 of 33 (82.05 percent); QHES, 79.76 of 100 (79.76 percent); CHEC, 15.54 of 19 (81.78 percent); and CHEERS, 20.25 of 24 (84.38 percent). Cost utility analyses had the highest methodologic and reporting quality scores: Drummond's checklist, 28.89 of 35 (82.54 percent); QHES, 86.56 of 100 (86.56 percent); CHEC, 16.78 of 19 (88.30 percent); and CHEERS, 20.8 of 24 (86.67 percent). The association (multiple R) between CHEC and CHEERS was strongest: CHEC, 0.953; Drummond's checklist, 0.907; and QHES, 0.909.

CONCLUSIONS

Partial economic evaluations in hand surgery are prevalent but not very useful. The Consensus on Health Economic Criteria and Consolidated Health Economic Evaluation Standards should be used in tandem when undertaking and evaluating economic evaluation in hand surgery.

Measuring Value: Cost-Effectiveness Analysis for Occupational Therapy

Stroke rehabilitation is expensive, and recent changes to Medicare reimbursement demand more efficient interventions. The use of cost-effectiveness analysis (CEA) can help occupational therapy practitioners, rehabilitation directors, and payers better understand the value of occupational therapy and decide whether or not to implement new treatments. The objective of this article is to illustrate the contribution of CEA to stroke rehabilitation using a hypothetical new intervention as an example. What This Article Adds: This article facilitates an understanding of the importance of CEA to occupational therapy. It also explains how CEA improves consistency with reporting standards for cost-effectiveness studies.

The long-term effect of neurodynamics vs exercise therapy on pain and function in people with carpal tunnel syndrome: A randomized parallel-group clinical trial

INTRODUCTION

Carpal tunnel syndrome (CTS) is a common disorder that limits function and quality of life. Little evidence is available on the long-term effect of neurodynamics and exercise therapy.

PURPOSE OF THE STUDY

This study aimed to examine the long-term effect of neurodynamic techniques vs exercise therapy in managing patients with CTS.

STUDY DESIGN

Parallel group randomized clinical trial.

METHODS

Of 57 patients screened, 51 were randomly assigned to either receiving four sessions of neurodynamics and exercise or home exercise therapy alone as a control. Blinded assessment was performed before treatment allocation, at treatment completion, and 6 months posttreatment. Outcome measures included Symptom Severity Scale (SSS), Functional Status Scale (FSS), Shortened version of the Disabilities of the Arm, Shoulder, and Hand (DASH), Numerical Pain Rating Scale, grip strength and range of motion.

RESULTS

Data from 41 individuals (52 hands) were analyzed. The neurodynamics group demonstrated significant improvement in all outcome measures at 1 and 6 months (P < .05). Mean difference in SSS was 1.4 (95% CI= 0.9-1.4) at 1 month and 1.6 (95% CI = 0.9-2.2) at 6 months. Mean difference in FSS was 0.9 (95% CI = 0.4-1.4) at 1 month and 1.4 (95% CI = 0.7-2.0) at 6 months. Significant between-group differences were found in pain score at 1 month (-1.93) and in FSS (-0.5) and Shortened version of DASH (-12.6) at 6 months (P < .05). No patient needed surgery 1 year after treatment.

CONCLUSIONS

Although both treatments led to positive outcomes, neurodynamics therapy was superior in improving function and strength and in decreasing pain.

A Systematic Review of Health State Utility Values in the Plastic Surgery Literature

Cost-utility analyses assess health gains acquired by interventions by incorporating weighted health state utility values (HSUVs). HSUVs are important in plastic and reconstructive surgery (PRS) because they include qualitative metrics when comparing operative techniques or interventions. We systematically reviewed the literature to identify the extent and quality of existing original utilities research within PRS.

Methods

A systematic review of articles with original PRS utility data was conducted in accordance with the Preferred Reporting Items for a Systematic Review and Meta-Analysis guidelines. Subspecialty, survey sample size, and respondent characteristics were extracted. For each HSUV, the utility measure [direct (standard gamble, time trade off, visual analog scale) and/or indirect], mean utility score, and measure of variance were recorded. Similar HSUVs were pooled into weighted averages based on sample size if they were derived from the same utility measure.

Results

In total, 348 HSUVs for 194 disease states were derived from 56 studies within seven PRS subspecialties. Utility studies were most common in breast (n = 17, 30.4%) and hand/upper extremity (n = 15, 26.8%), and direct measurements were most frequent [visual analog scale (55.4%), standard gamble (46.4%), time trade off (57.1%)]. Studies surveying the general public had more respondents (n = 165, IQR 103-299) than those that surveyed patients (n = 61, IQR 48-79) or healthcare professionals (n = 42, IQR 10-109). HSUVs for 18 health states were aggregated.

Conclusions

The HSUV literature within PRS is scant and heterogeneous. Researchers should become familiar with these outcomes, as integrating utility and cost data will help illustrate that the impact of certain interventions are cost-effective when we consider patient quality of life.

From expert to coach: health coaching to support behavior change within physical therapist practice

Background: Negative health behaviors are a significant risk factor for non-communicable diseases (NCDs) and are responsible for 40-50% of the burden of disease in the US population. Physical therapists (PTs) have the capacity to effect behavior change in their patients to reduce their risk of disease and promote health. Competence in health behavior change is recommended for physical therapists. One way to achieve this competence is by learning and adopting a health coaching approach. Objectives: To provide a theoretical and practical approach to applying a health coaching approach in physical therapist clinical practice. Methods: 1) Describe a health coaching approach to facilitating behavior change; 2) present behavior change theories, communication strategies, and models underpinning health coaching; and 3) provide suggestions for ways PTs can integrate health coaching in clinical practice. Results: Health coaching is a dynamic and collaborative approach to health behavior change that harnesses the patient's or client's values and strengths to realize their goals for health. Conclusion: Adopting a health coaching approach may enhance adherence to physical therapists' recommendations as well as improve health outcomes.

Does Societal Cost Information Affect Patient Decision-Making in Carpal Tunnel Syndrome? A Randomized Controlled Trial

Background: Despite studies demonstrating the effects of out-of-pocket costs on decision-making, the effect of societal cost information on patient decision-making is unknown. Given the considerable societal impact of cost of care for carpal tunnel syndrome (CTS), providing societal cost data to patients with CTS could affect decision-making and provide a strategy for reducing national health care costs. Therefore, we assessed the following hypotheses: (1) there is no difference in treatment choice (surgery vs no surgery) in a hypothetical case of mild CTS between patients randomized to receive societal cost information compared with those who did not receive this information; (2) there are no factors (eg, sex, experience with a previous diagnosis of CTS, or receiving societal cost information) independently associated with the choice for surgery; and (3) there is no difference in attitudes toward health care costs between patients choosing surgery and those who did not. Methods: In this randomized controlled trial using a hypothetical scenario, we prospectively enrolled 184 new and return patients with a nontraumatic upper extremity diagnosis. We recorded patient demographics, treatment choice in the hypothetical case of mild CTS, and their attitudes toward health care costs. Results: Treatment choice was not affected by receiving societal cost information. None of the demographic or illness factors assessed were independently associated with the choice for surgery. Patients declining surgery felt more strongly that doctors should consider their out-of-pocket costs when making recommendations. Conclusions: Providing societal cost information does not seem to affect decision-making and may not reduce the overall health care costs. For patients with CTS, health policy could nudge toward better resource utilization and finding the best care pathways for nonoperative and invasive treatments.

Health economic evaluation of different treatment strategies for peripheral entrapment mononeuropathies: a systematic review

Introduction: In this era of cost-conscious health systems, it is of utmost importance to identify and establish the most cost-effective treatment option. However, in the case of peripheral entrapment mononeuropathies there is alack of data regarding economically effective treatment strategies. Therefore, the objective was to conduct an economic evaluation including both costs and benefits of various treatment strategies applied to peripheral entrapment mononeuropathies to estimate the relative cost-effective treatment regimens.Areas covered: Over the 19 years, seven excellent-high quality economic evaluations of three types of peripheral entrapment mononeuropathies were identified in four countries. Our findings showed that surgery was the most cost-effective therapy followed by same cost efficacy of infiltrative therapy and conservative therapy for peripheral entrapment mononeuropathies. However, the fact that surgery was the most common comparator (n = 6) in our selected studies cannot be neglected.Expert opinion: Due to huge methodological variability, the finding of surgery as the cost-effective treatment strategy remains tentative and the decision about the most suitable clinical and cost-effective therapy should be individualized from case to case. Moreover, the economic evaluation of all possible treatment strategies for peripheral entrapment mononeuropathies over alonger period of analysis is required in future studies.

Association of the role of personal variables and nonoccupational risk factors for work-related carpal tunnel syndrome

OBJECTIVES

The purpose of this study was to identify personal variables and nonoccupational risk factors for carpal tunnel syndrome and to analyse the strength of association of these factors.

METHODS

We performed a case-control study with 162 cases and 300 controls. We studied consecutive patients with an electrophysiologically confirmed diagnosis of symptomatic carpal tunnel syndrome. Univariate analysis was performed in the case group and control comparing them for presence of various risk factors. Multivariate analysis was carried out through logistic regression.

RESULTS

The mean BMI and age were greater in the case group than in the control. Multivariate analysis showed that BMI (OR = 1.05, 95% CI = 1.01-1.11) and arterial hypertension (OR = 4.63, 95% CI = 2.88-7.44) were the only factors significantly associated with carpal tunnel syndrome. The age, cigarette smoking and alcohol drinking were at the edge of significance.

CONCLUSIONS

Carpal tunnel syndrome is the most common peripheral neuropathy and has been related to occupational activities in some but not all studies. Clarifying this relationship has important implications for workers' compensation systems. Based on our findings, BMI and arterial hypertension are considered to be the most significant risk factors of carpal tunnel syndrome in our study.

Manual Therapy Versus Surgery for Carpal Tunnel Syndrome: 4-Year Follow-Up From a Randomized Controlled Trial

OBJECTIVE

No study to our knowledge has investigated the effects longer than 1 year of manual therapy in carpal tunnel syndrome (CTS). The purpose of this study was to investigate the effects of manual therapy versus surgery at 4-year follow-up and to compare the post-study surgery rate in CTS.

METHODS

This randomized controlled trial was conducted in a tertiary public hospital and included 120 women with CTS who were randomly allocated to manual therapy or surgery. The participants received 3 sessions of physical therapy, including desensitization maneuvers of the central nervous system or carpal tunnel release combined with a tendon/nerve gliding exercise program at home. Primary outcome was pain intensity (mean and the worst pain). Secondary outcomes included functional status, symptom severity, and self-perceived improvement measured using a global rating of change scale. Outcomes for this analysis were assessed at baseline, 1 year, and 4 years. The rate of surgical intervention received by each group was assessed throughout the study.

RESULTS

At 4 years, 97 (81%) women completed the study. Between-group changes for all outcomes were not significantly different at 1 year (mean pain: mean difference [MD] = -0.3, 95% CI = -0.9 to 0.3; worst pain: MD = -1.2, 95% CI = -3.6 to 1.2; function: MD = -0.1, 95% CI = -0.4 to 0.2; symptom severity: MD = -0.1, 95% CI = -0.3 to 0.1) and 4 years (mean pain: MD = 0.1, 95% CI = -0.2 to 0.4; worst pain: MD = 0.2, 95% CI = -0.8 to 1.2; function: MD = 0.1, 95% CI = -0.1 to 0.3; symptom severity: MD = 0.2, 95% CI = -0.2 to 0.6). Self-perceived improvement was also similar in both groups. No between-group differences (15% physical therapy vs 13% surgery) in surgery rate were observed during the 4 years.

CONCLUSIONS

In the long term, manual therapy, including desensitization maneuvers of the central nervous system, resulted in similar outcomes and similar surgery rates compared with surgery in women with CTS. Both interventions were combined with a tendon/nerve gliding exercise program at home.

IMPACT

This is the first study to our knowledge to report clinical outcomes and surgical rates during a 4-year follow-up and will inform decisions regarding surgical versus conservative management of CTS.

LAY SUMMARY

Women with CTS may receive similar benefit from a more conservative treatment-manual therapy-as they would from surgery.

Understanding central sensitization for advances in management of carpal tunnel syndrome

Carpal tunnel syndrome is the most common nerve compression disorder of the upper extremity, and it is traditionally considered a peripheral neuropathy associated with a localized compression of the median nerve just at the level of the carpal tunnel. Surgery and physiotherapy are treatment approaches commonly used for this condition; however, conflicting clinical outcomes suggest that carpal tunnel syndrome may be more complex. There is evidence supporting the role of peripheral nociception from the median nerve in carpal tunnel syndrome; however, emerging evidence also suggests a potential role of central sensitization. The presence of spreading pain symptoms (e.g. proximal pain), widespread sensory changes, or bilateral motor control impairments in people presenting with strictly unilateral sensory symptoms supports the presence of spinal cord changes. Interestingly, bilateral sensory and motor changes are not directly associated with electrodiagnostic findings. Other studies have also reported that patients presenting with carpal tunnel syndrome exhibit neuroplastic brainstem change supporting central sensitization. Current data would support the presence of a central sensitization process, mediated by the peripheral drive originating in the compression of the median nerve, in people with carpal tunnel syndrome. The presence of altered nociceptive gain processing should be considered in the treatment of carpal tunnel syndrome by integrating therapeutic approaches aiming to modulate long-lasting nociceptive barrage into the central nervous system (peripheral drive) and strategies aiming to activate endogenous pain networks (central drive).

Validation of the Slovakian version of Boston Carpal Tunnel Syndrome Questionnaire (BCTSQ)

INTRODUCTION

The most common occupational disease is carpal tunnel syndrome. The aim of this study was to translate and validate the Slovakian version of BCTSQ.

METHODS

The original questionnaire was translated into the Slovakian language by two expert translators. Cronbach's alpha coefficient was used to analyze the internal consistency of the questionnaire. Construction validity was evaluated by using Pearson's correlation coefficient and Spearman's rank correlation. The results were processed in the statistical program SPSS 24. The level of significance p > 0.05 was considered significant. To analyze the validity, a factor analysis of the BCTSQ and the correlation between BCTSQ and SF-36 were obtained.

RESULTS

A total of 32 employees at risk of local muscular overload completed the BCTSQ and Health Questionnaire SF-36. Cronbach's alpha for SSS was >0.8. The alpha coefficient for FSS was >0.9. The Pearson's coefficient and Spearman's rank correlation was >0.9 for each domain. Cronbach's alpha for SF-36 was >0.7 and the Pearson's coefficient and Spearman's rank correlation was >0.6 and p-values <0.001.

CONCLUSIONS

The questionnaire has sufficient reliability, validity and can be a suitable tool for the evaluation of subjective response of employees at the risk of local muscular overload, as well as of patients with carpal tunnel syndrome.

Long-term patient observation after conservative treatment of carpal tunnel syndrome: a summary of two randomised controlled trials

Background

Physiotherapy of carpal tunnel syndrome (CTS) involves manual therapy based on neurodynamic techniques. Until now, two randomized controlled trials have shown that immediately after therapy, CTS patients who received neurodynamic techniques had significant improvement in nerve conduction, pain, symptom severity (SSS), functional state (FSS), muscle strength (MS) and two-point discrimination (2PD). However, long-term effects seem to be more important, as they are the only ones that can significantly improve the patient's health and influence economic and social costs. Thus, the objective of this study was to evaluate the long-term (six months) effects of neurodynamic techniques in the conservative treatment of CTS patients.

Methods

Carpal tunnel syndrome patients (107) from two previously published randomised clinical trials were observed for six months after the treatment based on neurodynamic techniques.

Results

The sensory conduction velocity, motor conduction velocity, and motor latency were not subject to statistically significant changes within six months after therapy (p > 0.05). In both groups, there was further pain reduction (p < 0.05). In Group B, the symptom severity improved significantly (p < 0.05), while the functional status in both groups remained unchanged (p > 0.05). In both groups, there was muscle strength improvement (p < 0.05). Two-point discrimination remained unchanged six months after the therapy.

Conclusion

The use of manual therapy based on neurodynamic techniques maintains the beneficial effects 6 months after therapy in CTS patients.

An investigation of Australian osteopaths' attitudes, skills and utilisation of evidence-based practice: a national cross-sectional survey

Background

Osteopaths are an integral member of the health care team, playing a pivotal role in the provision of care for patients with musculoskeletal disorders. Osteopaths, like other health care providers, are under increasing pressure to deliver evidence-based health care and to improve patient outcomes. However, the extent to which osteopaths engage in evidence-based practice (EBP), particularly in Australia, is not well understood. This study therefore set out to investigate the attitudes, skills and use of EBP, and perceived barriers and enablers of EBP uptake, among osteopaths practicing in Australia.

Methods

National cross-sectional survey of Australian registered osteopaths. Eligible participants were invited by email and other digital media recruitment strategies to complete the online Evidence-Based Practice Attitude and Utilisation Survey (EBASE).

Results

A total of 332 osteopaths completed the survey. The demographic characteristics of respondents were generally consistent with the characteristics of the Australian osteopathy workforce. The respondents were mostly favourable of EBP, with the majority agreeing or strongly agreeing that EBP assists in making decisions about patient care (86.7%) and improves the quality of patient care (75.6%). While most respondents (88.3%) had some training in EBP, most reported a moderate level of perceived skill in EBP. The majority of respondents engaged infrequently (0–5 times) in EBP activities within the last month, and most indicated that a very small or small proportion of their clinical practice was based on clinical research evidence. Leading barriers to the uptake of EBP were lack of time and lack of clinical evidence in osteopathy. Key enablers of EBP uptake were access to the internet and online databases at work, and access to full-text articles and EBP education materials.

Conclusions

Osteopaths participating in the survey were largely supportive of evidence-based practice, yet engaged infrequently in EBP activities. An important next step in this research is to identify suitable strategies that effectively improve EBP uptake in osteopathy, and perchance, improve patient outcomes.
