The impact of a hand therapy workplace-based educational approach on the management of lateral elbow tendinopathy: A randomized controlled study

Efficacy of extension wrist hand orthosis on pain, grip strength and electromyographic activities in lateral epicondylitis: A randomized single-blind clinical trial

BACKGROUND

Lateral epicondylitis (LE) is one of the most common work-related complications characterized by pain, decreased grip strength and dysfunction of upper limb. Although conservative management such as physiotherapy and orthosis is reported as first line of treatment, sufficient evidence to decide their effectiveness is lacking and remains controversial.

PURPOSE

The current study evaluated and compared the efficacy of a custom-made extension wrist hand orthosis adjunct to usual physiotherapy and therapeutics alone for subjects with LE.

STUDY DESIGN

Prospective randomized single-blinded clinical trial.

METHODS

62 subjects with LE were selected as samples using convenience method in this experimental study. They were randomly divided into two groups: usual physiotherapy only and its combination with orthosis. Pain and grip strength were measured using Visual Analog Scale and Jamar hydraulic digital hand dynamometer. Muscle activity of extensor carpi radialis brevis during hand gripping was measured using surface electro-myographic by PowerLab electromyography (AD Instruments, Castle Hill, Australia). Data analysis and comparison were performed for baseline and post-intervention (12weeks).

RESULTS

After 12weeks of treatment, there were significant differences in mean scores of pain (1.22 ± 0.51, p = 0.001), maximum voluntary grip strength (5.82 ± 7.84, p = 0.04), and extensor carpi radialis brevis muscle activation (0.082 ± 0.094, p = 0.02) between the therapeutics alone group and the therapeutics plus orthosis group. Compared to therapeutics alone, those getting a combination of physiotherapy and orthosis had greater treatment efficacy (p < 0.05).

CONCLUSIONS

Both postintervention (12-week) treatments could affect pain scores, grip strength, and extensor muscle activation. Custom-made extension wrist hand orthosis adjunct to usual physiotherapy is more effective than therapeutics alone in subjects with LE. Therefore, the use of wrist orthosis adjunct to physiotherapy should be recommended in rehabilitation settings for LE.

Managing work‐related lateral elbow tendinopathy: Australian hand therapist's experiences with workplace‐based interventions

INTRODUCTION

Lateral elbow tendinopathy (LET) is one of the most prevalent work-related musculoskeletal conditions. Current treatments for LET focus mainly on the physiological symptoms of pain, grip strength, and function. Recently, a novel workplace-based hand therapy educational intervention, Working Hands-ED, was developed based on the Person-Environment-Occupation- Performance model, International Classification of Functioning, Disability and Health framework and the Australian Clinical Framework for the Delivery of Health Services. Combining a hand therapist's specialised knowledge and skills in upper limb rehabilitation with an approach that considers injured workers' occupations and work environments may provide a more holistic approach to managing work-related LET. To the best of our knowledge, no previous studies have investigated the experiences of hand therapists who perform workplace-based educational interventions for the management of LET.

METHOD

An exploratory, descriptive qualitative design using semi-structured interviews was used with hand therapists who delivered the novel hand therapy intervention Working Hands-ED.

FINDINGS

Ten occupational therapists working in hand therapy were interviewed. Three main themes and eight subthemes were identified from interview data: Person-centred approach, opportunity for therapists to provide enhanced service, and improved stakeholder engagement in the return-to-work process. Logistical challenges such as the costs and time spent away from the clinical setting were identified.

CONCLUSION

All hand therapists reported delivering Working Hands-ED when managing work-related LET was a positive experience for them. They believed that the novel intervention could provide a more holistic approach to care that added value to their service delivery; however, there were some logistical factors to consider including the additional time and costs associated with the intervention.
