Effectiveness of occupational therapy interventions on function and occupational performance among adults with conditions of the hand, wrist, and forearm: A systematic review and meta-analysis

INTRODUCTION

This systematic review and meta-analysis examines the effectiveness of occupational therapy interventions for adults with conservatively managed conditions of the hand, wrist, and forearm.

METHODS

Searches were carried out in CINAHL, Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Database of Systematic Reviews, MEDLINE (OVID), EMBASE, and PubMed. Grey literature was searched for via Google Scholar. A systematic literature search was undertaken for randomised studies that examined occupational therapy interventions for treatment of hand, wrist, and forearm conditions. The primary outcome was function, with secondary outcomes of occupational performance, satisfaction with occupational performance, pain, and quality of life. Meta-analyses were completed, and GRADE was used to determine the certainty of evidence.

RESULTS

Twelve studies with 1429 participants were identified. Interventions included combinations of occupation-based intervention, assistive device provision, education, orthosis provision, and exercise programmes for arthritis, carpal tunnel syndrome, and fracture and tendon injuries of the hand, wrist, and forearm. Occupational therapy resulted in an improvement of function (REM, SMD -0.27, 95% CI -0.00 to -0.53, I2  = 69%, low certainty evidence) (p = 0.05), occupational performance (REM, SMD 0.83, 95% CI 1.61-0.06, I2  = 91%, low certainty evidence) (p = 0.04), satisfaction with occupational performance (REM, SMD 0.74, 95% CI 1.42-0.05, I2  = 89%, low certainty evidence) (p = 0.03), and pain reduction (FEM, MD -1.35, 95% CI -0.84 to -1.86, I2  = 0%, moderate certainty evidence) (p < 0.00001).

CONCLUSION

Further high-quality research is recommended to determine the effects of occupational therapy interventions on specific upper limb conditions, inclusive of a broader range of clinical and patient reported outcome measures.

Evidence of internal construct validity of SOC-13 total score, for use in hand therapy

PURPOSE

The objective was to examine whether the 13-item Sense of coherence scale (SOC-13) can be reported as a unidimensional interval-scale metric, when new approaches based on the Rasch model to address local item dependency are applied, and to determine whether an interval-scale scoring can be made available.

METHODS

Data were derived from two samples of patients with hand-related disorders (merged n = 915). Rasch analyses of the SOC data were conducted using item-level analysis and a testlet approach.

RESULTS

Initial item-level analysis of the SOC-13 confirmed previous findings of misfit to the Rasch model. In resolving local dependency by constructing three testlets, which corresponded to the three components of the SOC construct, fit to the Rasch model (χ2(df) = 43.11 (27), p = 0.163) and unidimensionality of the SOC-13 could be established. A transformation table was successfully created to convert the SOC-13 raw ordinal score to corresponding Rasch interval-scaled values.

CONCLUSIONS

The results of this study indicate that data obtained by the SOC-13 can be regarded as essentially unidimensional, and an interval-scale transformation table of the SOC-13 total scores was developed, for use in clinical practice and research on coping resources in patients with hand-related disorders.

An occupation-based intervention in patients with hand-related disorders grouped using the sense of coherence scale-A randomized controlled trial

STUDY DESIGN

A nonblinded randomized controlled trial.

INTRODUCTION

Occupation-based interventions are superior to physical exercise-based interventions in patients with activity limitations. However, only a few studies have examined the effect in patients with hand-related disorders. Patients recover heterogeneously, which could be due to personal factors, such as sense of coherence (SOC).

PURPOSE OF THE STUDY

To investigate the effectiveness of an occupation-based intervention for patients with hand-related disorders and whether SOC can give an indication of the expected effects.

METHODS

A total of 504 patients were stratified into three SOC groups and then randomized to either an occupation-based intervention, including physical exercises (OBI) or a physical exercise-based occupation-focused intervention. The primary outcome, functioning, was measured using the Disability of the Arm, Shoulder and Hand questionnaire. Primary endpoint was at three months. Patients were followed up for a year.

RESULTS

No significant difference was found in primary outcome analysis. Nevertheless, patients receiving OBI had a statistically significant and greater change in satisfaction with their occupational performance at one, two, and three months follow-up. Patients with a weak SOC had worse functioning and lower health-related quality of life than those in the other groups, at all times.

CONCLUSIONS

OBI as delivered in this study was not superior to physical exercise-based occupation-focused intervention in this patient group. However, in taking a client-centered approach, we recommend that OBI be based on individual needs, given that patients had a statistically greater change in score regarding satisfaction with their occupational performance. It is evident that patients with a weaker SOC have a lower level of functioning. This knowledge should inform clinical practice.

Occupational performance problems identified by 507 patients: An insight that can guide occupation-based hand therapy

Introduction

Several barriers challenge the use of occupation-based interventions in hand therapy. An outpatient clinical setting can be prepared in such a way as to address the most common occupational performance problems which might promote an occupation-based intervention. To this end, more knowledge is needed about which problems patients with hand-related disorders consider most important.

Methods

Interviews using the Canadian Occupational Performance Measure (COPM)were conducted with 507 patients. Data were entered into Microsoft Excel in the COPM categories: Self-care, productivity and leisure and analysed using descriptive statistics. Data concerning main problem areas were categorized according to the Taxonomic Code of Occupational Performance (TCOP). The analysis included the number of prioritized occupational performance problems (NPOPP) in each COPM category/subcategory; the NPOPP in each category is relative to gender and age and the most frequent problems.

Results

The total NPOPP was 2384. Problems within productivity and self-care constituted the largest proportion, respectively, 46% and 40%. Gender or age affected the NPOPP in each category to a limited extend. Problems were expressed at all levels in the TCOP, except the lowest level. The most frequently expressed problem was use of utensils when eating.

Conclusion

The problems mostly concern productivity and self-care, regardless of gender or age. Patients consider problems at the levels of occupation, activities, tasks and actions to be important and meaningful to address in their intervention. This study provides useful knowledge that can be applied when preparing a setting to address the most common problems, which could lead to the promotion of occupation-based interventions.
