Occupational therapy interventions for work-related injuries and conditions of the forearm, wrist, and hand: a systematic review

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.

Visualization of Human Hand Tendon Mechanical Anisotropy in 3-D Using High- Frequency Dual-Direction Shear Wave Imaging

High-resolution ultrasound shear wave elastography has been used to determine the mechanical properties of hand tendons. However, because of fiber orientation, tendons have anisotropic properties; this results in differences in shear wave velocity (SWV) between ultrasound scanning cross sections. Rotating transducers can be used to achieve full-angle scanning. However, this technique is inconvenient to implement in clinical settings. Therefore, in this study, high-frequency ultrasound (HFUS) dual-direction shear wave imaging (DDSWI) based on two external vibrators was used to create both transverse and longitudinal shear waves in the human flexor carpi radialis tendon. SWV maps from two directions were obtained using 40-MHz ultrafast imaging at the same scanning cross section. The anisotropic map was calculated pixel by pixel, and 3-D information was obtained using mechanical scanning. A standard phantom experiment was then conducted to verify the performance of the proposed HFUS DDSWI technique. Human studies were also conducted where volunteers assumed three hand postures: relaxed (Rel), full fist (FF), and tabletop (TT). The experimental results indicated that both the transverse and longitudinal SWVs increased due to tendon flexion. The transverse SWV surpassed the longitudinal SWV in all cases. The average anisotropic ratios for the Rel, FF, and TT hand postures were 1.78, 2.01, and 2.21, respectively. Both the transverse and the longitudinal SWVs were higher at the central region of the tendon than at the surrounding region. In conclusion, the proposed HFUS DDSWI technique is a high-resolution imaging technique capable of characterizing the anisotropic properties of tendons in clinical applications.

The use of occupation based interventions among certified hand therapists

BACKGROUND: The effectiveness of occupation-based hand therapy and the barriers to the use of occupation-based interventions (OBIs) have been established, but the current experience of hand therapists using OBIs and the extent of the use of OBIs in practice is unknown. OBJECTIVE: This study aimed to identify the frequency that occupational therapists who are Certified Hand Therapists (CHTs) utilized OBIs, how occupational therapists who are CHTs described their application of OBIs, and identify the supports and barriers to the application of OBIs. METHODS: Twenty-nine participants completed a survey that included 27 questions. The questions consisted of close ended, Likert scale, and multiple-choice questions which were analyzed quantitatively, and open-ended questions which were analyzed qualitatively. RESULTS: The majority of the participants, 57.7%, reported implementing OBI at least 75% of the time. Barriers and supports to the use of OBIs reported include a lack of equipment and therapist creativity, and support for the use of OBIs included the therapist’s creativity, support from the facility, the availability of equipment, and the intrinsic motivation of therapists. Descriptions of OBI application included activity simulation, adaptive equipment use, and participation in meaningful activity. CONCLUSION: Although the use of OBIs in hand therapy may be expanding, occupational therapy practitioners and educators have a role to play in overcoming the remaining barriers to occupation-based hand therapy. Additional research is needed to gain further insight into use of occupation-based intervention by occupational therapists who are CHTs and explore the effect of education on promoting the use of OBIs.

Workplace-based rehabilitation with garment workers: A multiple case study

BACKGROUND: Garment workers are at risk of developing work-related upper limb disorders (WRULD) due to the highly repetitive nature of their work. Workplace-based rehabilitation (WBR) facilitates improvement in work performance by providing intervention at the worker’s place of work. OBJECTIVE: This study aims to determine the documented outcomes of workplace-based occupational therapy rehabilitation of garment workers with upper limb conditions. METHODS: A multiple case study design was used through a retrospective record review. All garment workers with upper limb conditions who were treated at a student occupational therapy practice in Cape Town, South Africa, with pre- and post-intervention outcome assessment, were included in the study (n = 7). Data were extracted from occupational therapy and medical files. RESULTS: 70% of the cases (n = 5) improved after WBR while 30% of cases showed no improvement or deterioration. Participants received 3– 5 individual WBR sessions of approximately 30 minutes each, over a period of 4 to 6 weeks. Interventions included workstation adaptations, job rotation, psychoeducation, work task modification, assistive technology and exercise programmes. Outcome measures most commonly used were the RULA, DASH, Boston Carpal Tunnel Questionnaire and pain intensity using the VAS. CONCLUSION: Workplace-based occupational therapy can be effective at improving upper limb function, pain and ergonomic risk amongst garment workers with upper limb conditions.

Perspectives and Influences on Occupation-Based Hand Therapy

Background. Occupational therapists practicing hand therapy are challenged to implement occupation-based practices (OBPs) due to the strong influence of the medical model. Purpose. To explore hand therapists' perceptions of OBP and describe occupation-based interventions (OBIs) in hand therapy. Method. Qualitative content analysis (QCA) was used to analyze semi-structured interviews with seven hand therapists. Findings. Six themes emerged: (1) OBP denotes treatment that is customized to ensure individual meaningfulness to each client; (2) the client-therapist relationship is a foundational element central to OBP in hand therapy; (3) goal setting serves as an important link between biomechanics and occupation; (4) OBP in hand therapy encompasses a spectrum of both OB and non-OB interventions; (5) various contextual factors influence OBI; (6) advanced experience in hand therapy facilitates enactment of tailored OBI. Implications. Comprehension of multiple aspects of occupation-based methods in hand therapy exemplifies best practices for clinicians to benefit clients and the profession's identity.

Workplace-based occupational therapy for mental health in Africa: a scoping review protocol

INTRODUCTION

Although mental health at work is a pressing and growing concern, mental healthcare accounts for less than 2% of global healthcare, with marked inequality across continents. Africa has the smallest proportion of mental health service providers, and the highest rate of out-of-pocket expenditure for mental health service users. Poor mental health at work results in costs to workers, employers and the economy. This review aims to collaborate with stakeholders to identify literature on workplace-based occupational therapy interventions supporting the mental health of workers in Africa.

METHODS AND ANALYSIS

We will search Medline (PubMed), EBSCOhost (Academic Search Premier, AfricaWide Information, CINAHL, Health Source: Nursing/Academic), Scopus, Web of Science, Sabinet, Cochrane and OTSeeker for qualitative and quantitative primary research studies. Grey literature will be searched via Sabinet and ProQuest. No language or date restrictions will be applied. Title and abstract screening as well as full-text screening will be done independently by two reviewers. Data extracted will include information about the articles, characteristics of studies and interventions, and findings. Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews guidelines will be used for reporting results. Three groups of stakeholders will be consulted during the review process: service users/workers, employers and service providers/occupational therapists.

ETHICS AND DISSEMINATION

This scoping review does not require ethics approval. Findings of the review will be disseminated through stakeholder engagements, peer-reviewed publications and conference presentations.

Comparative efficacy of the dorsal application of Kinesio tape and splinting for carpal tunnel syndrome: A randomized controlled trial

BACKGROUND

Carpal tunnel syndrome (CTS) symptoms are problematic especially when signs and symptoms are not substantial enough to require surgical intervention. Conservative treatments have mixed effectiveness, yet are one of the best options for mild to moderate CTS. Kinesio tape is an emerging modality, as it provides biomechanical support while allowing movement.

PURPOSE

The purpose of this study was to determine the efficacy of dorsal application of Kinesio tape on occupational performance as measured by pain and function in individuals with mild to moderate CTS, as compared with the accepted nonsurgical intervention of general cockup orthosis and lumbrical stretching exercises versus sham tape.

STUDY DESIGN

Single-blind randomized controlled trial.

METHODS

Forty-four participants (68 wrists) with CTS were randomized to one of three interventions: Kinesio tape group, sham group, or standard protocol group. Each completed baseline and four subsequent measurements of numeric pain rating scale, visual analog scale (VAS), Boston Carpal Tunnel Questionnaire (BCTQ), grip and pinch, with application of intervention every three days. Daily symptom journals were completed, standard protocol group recorded wearing schedule and exercises.

RESULTS

In the forearm and wrist, a significant reduction in median numeric pain rating scale pain scores in Kinesio tape group was observed (r = 0.76, P = .01; r = 0.77, P = .01; respectively), but not in the standard protocol group (r = 0.51, P = .17; r = 0.53, P = .11) and sham group (r = 0.46, P = .30; r = 0.39, P = .43) with a minimal clinically important difference of 1.0. In the Kinesio tape group, the forearm (24%) and wrist (36%) reached the clinical significance as compared with the standard protocol forearm (18%) and wrist (32%). The minimal clinically important difference for pain reduction on the visual analog scale was 1.64. Kinesio tape and sham group had significant improvement in function, but not the standard protocol group.

DISCUSSION

This study provides promising evidence for the use of Kinesio tape as a possible conservative intervention for management of symptoms in individuals with mild to moderate CTS. The study also illuminates new considerations of younger, active individuals reporting signs and symptoms of CTS as well as mechanism of effects on pain reduction.

CONCLUSIONS

Kinesio tape provided additional improvement in pain and function as compared to the standard approach.

Psychosocial influences in the development of cumulative trauma disorders

STUDY DESIGN

This study is a single-phase, qualitative study using grounded theory methodology.

INTRODUCTION

Cumulative trauma disorders (CTDs) are musculoskeletal disorders that impact health and productivity. CTD risk factors are present in the workplace, home, and community. Occupational and physical therapists specializing in hand and upper extremity rehabilitation (hand therapists) are widely involved with this population. Hand therapists often employ a medical model in the assessment and treatment of these conditions; however, the medical model has not proven to be consistently effective in relieving symptoms or producing a durable return to daily living activities.

PURPOSE OF THE STUDY

The purpose of this study was to explore the lived experiences of individuals diagnosed with CTD, and investigate the psychosocial phenomena influencing CTD development as an impediment to occupational performance.

METHODS

The principal investigator recruited 11 participants who met specific inclusion criteria, then used semi-structured interviews aimed at exploring the lived experiences of the participants while investigating the psychosocial phenomenon influencing CTD development. Interviews were transcribed and analyzed using a process of constant comparison, up until saturation occurred. Trustworthiness techniques were used in the data analysis phase and included peer reviews and member checking.

FINDINGS

The findings suggest that many psychosocial factors contribute to the development and impact of CTDs, at both onset of symptoms and throughout the duration of the condition. A significant number of contextual factors influence participants' function, behavior, relationships, and the course of medical care. Themes derived from the participants' expressions, included the following: 1) an initial strategy of "work through the pain," can be detrimental to symptom resolution and leads to progressive failure to meet role expectations, 2) a pervasive notion of CTDs as "an invisible disability," leaving participants feeling isolated and frustrated when significant others fail to offer support or reject them, 3) participants often delayed reporting symptom development to employers, family members, and medical personnel, risking permanent injury and disability, 4) a "stigma" is attached to CTDs that encourages isolation; however, the social support of even one significant other in a person's life can facilitate adaptation.

DISCUSSION AND CONCLUSION

All participants experienced hardship because of their conditions; however, two of the eleven participants capably navigated the process, using past experience and support from family and employer to successfully adapt. These findings offer support that CTDs are adaptive disorders. The study's conclusion suggests a new model to describe CTD dysfunction and presents new ways of thinking for clinicians who treat the CTD population.

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.

"Today I felt like my work meant something": A pilot study on job crafting, a coaching-based intervention for people with work limitations and disabilities

BACKGROUND

People's work life and career can ultimately be deconstructed to the day-to-day job tasks they perform, the people they interact with, and the value and meaning attached to their jobs. Individuals with work limitations and disabilities consistently experience disparities in the workplace resulting in a less than optimal work experience in all three areas.

OBJECTIVE

The purpose of this study is to conduct a pilot study to test the effectiveness of job crafting as an occupational therapy (OT) intervention strategy for workers with health conditions and impairments. Job crafting is a proactive, strengths-based, bottom-up approach where workers renegotiate and redefine their job tasks in a personally meaningful way.

METHODS

A mixed-methods study (n = 11) was conducted with workers who experience work limitations and disabilities. OT graduate students conducted in-depth interviews and facilitated the use of job crafting to improve work-related outcomes. Pre-and post-intervention data was analyzed using descriptive statistics and Wilcoxon signed-rank tests. Qualitative data was transcribed, coded, and synthesized.

RESULTS

The job crafting intervention improved work-related self-efficacy (p < 0.05) and crafting behaviors (p < 0.05) in the workplace. Participants accomplished goals to manage their work limitations, meet job demands, and other non-disability related challenges.

CONCLUSIONS

Job crafting has the potential to be used as a holistic OT intervention strategy to improve work-related self-efficacy among workers with work limitations and disabilities.

Development of nursing care guideline for burned hands

Aim

To develop an evidence-based guideline to care for hand-burned patients.

Design

An integrative review.

Method

The search was conducted of EMBASE, PubMed, Web of Science, SCOPUS, Clinical Key, Iranmedex, Magiran, Scientific Information Database (SID), Cochran, CINAHL and Google Scholar databases from January 2000-August 2019. Following the formation of the research team, two researchers independently selected the eligible studies. The initial search resulted in 2,230 records; ultimately, 40 articles were identified to be the review after screening the records based on the study's inclusion and exclusion criteria. Quality of selected studies was evaluated with the MMAT method.

Results

Data syntheses of selected studies, coded by highlighting the relevant parts of the text, and assigning code words to these areas were done. Following this, a constant comparison was used to develop categories by combining codes. Finally, hand burns nursing care guideline was developed by categorizing descriptive themes in two main phases.

Conclusion

This review results have shown that evidence-based guidelines present high-quality recommendations for the healthcare team, which improves the quality of clinical care. Due to a lack of established guidelines in our context, it seems to be helpful to use evidence-based guidelines in managing burned hands.

Psychometric properties of the Assessment of Motor and Process Skills in patients undergoing rehabilitation following hand-related disorders

Introduction

Assessment of Motor and Process Skills (AMPS) has been proven to be a suitable measurement tool for assessing performance-based ADL ability; however, its reliability and validity have not been tested on patients with hand-related disorders.

Methods

Patients referred for outpatient hand rehabilitation were assessed with AMPS, The Canadian Occupational Performance Measure (COPM), dynamometer and goniometer at baseline and after eight weeks of hand therapy. Construct validity and responsiveness of AMPS were assessed by hypothesis testing. Construct validity was assessed by correlating the baseline score of AMPS with the baseline score of the other measurement tools. Responsiveness was assessed by correlating the change scores of each measurement tool with a Global Rating Scale.

Results

Fifty-one patients were recruited. The construct validity of AMPS indicated that the various measurement tools captured different aspects to functioning from the AMPS, as the correlations between AMPS and the other measurement tools were generally weak to low (r < 0.25 to 0.49). AMPS was less responsive than COPM when correlated with the GRS. The correlation between COPM and GRS was r = 0.62 compared with the AMPS motor, r = 0.45 and AMPS process, r = 0.33. Relative responsiveness of AMPS is similar to that of the dynamometer (r = 0.39) and goniometer (r = –0.34).

Discussion

In a sample of 51 patients, this study found that the construct validity of AMPS seemed to be moderate, while the responsiveness of AMPS seemed to be poor. However, due to the small sample size no conclusions can be made, and should be further assessed in larger studies.

Evaluation of Hand Tendon Movement by Using High-Frequency Ultrasound Vector Doppler Imaging

OBJECTIVE

Injuries to the hands, wrists, and fingers often involve damage to the tendons. The ability to measure tendon movements during the rehabilitation process can provide clinicians with important information in the quantification of tendon injuries. Conventionally, the tendon is considered a single spring-like structure during force transmission, and its twisted structure is neglected. Recently, clinicians believed that the twisted fiber structure (which enables tendon rotation during movement) of the tendon can provide it with a degree of elasticity and improve the efficiency of force transmission. However, observation of the hand tendon rotation in vivo by using the current imaging modalities is difficult.

METHODS

In this study, a 40-MHz high-frequency vector Doppler imaging (HFVDI) was used to visualize the movement of the hand tendon during muscle contraction. The performance of HFVDI was verified using a rotation phantom experiment. Two human experiments were designed in the present study: 1) participants were allowed to bend their distal and proximal interphalangeal (DIP and PIP) joints of fingers freely and 2) the PIP joint of the finger was fixed such that only the DIP could be moved. The HFVDIs of the flexor digitorum superficialis (FDS) and flexor digitorum profundus (FDP) tendons were obtained in the transverse and longitudinal views to observe the movements of the hand tendon during finger movements.

RESULTS

The average longitudinal displacements of the FDS and FDP were approximately 3-4 mm for free bending of the finger; however, it was reduced when only the DIP was moved. The rotational phenomenon of the FDS and FDP tendons was observed in the transverse view, which demonstrated the different rotational behaviors of the FDS and FDP fibers during muscle contraction.

CONCLUSION

All the results validated the potential of HFVDI as a novel tool for visualizing tendon rotation and would be useful in providing quantitative information regarding tendon function to determine the rehabilitation process following injuries.

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.

Similar 2-point discrimination and stereognosia but better locognosia at long term with an independent home-based sensory reeducation program vs no reeducation after low-median nerve transection and repair

STUDY DESIGN

Prospective controlled study.

INTRODUCTION

Previous studies evaluated the effectiveness of sensory reeducation (SR) after peripheral nerve injury and repair. However, evidence for long-term clinical usefulness of SR is inconclusive.

PURPOSE OF THE STUDY

The purpose of this study is to compare the sensory results of patients with low-median nerve complete transection and microsurgical repair, with and without SR at long term.

METHODS

We prospectively studied 52 consecutive patients (mean age, 36 years; range, 20-47 years) with low-median nerve complete transection and microsurgical repair. When reinnervation was considered complete with perception of vibration with a 256-cycles per second tuning fork (mean, 3.5 months after nerve injury and repair), the patients were sequentially allocated (into 2 groups [group SR, 26 patients, SR; group R, 26 patients, reassured on recovery without SR). SR was conducted in a standardized fashion, in 2 stages, as an independent home-based program: the first stage was initiated when reinnervation was considered complete, and included instruction in home exercises to identify familiar objects and papers of different roughness, and localization of light touch (eyes open and closed); the second stage was initiated when the patients experienced normal static and moving 2-point discrimination (2PD) at the index fingertip of injured hand, and included instruction in home exercises for stereognosia, supplementary exercises for localization of light touch, and identification of small objects (eyes open and closed). Exercises were prescribed for 5-10 minutes, 4 times per day. At 1.5, 3, and 6 years after nerve injury and repair, we evaluated the static and moving 2PD, stereognosia with the Moberg's pick-up test, and locognosia with the modified Marsh test. Comparison between groups and time points was done with the nonparametric analysis of variance (Kruskal-Wallis analysis of variance).

RESULTS

Static and moving 2PD and stereognosia were not significantly different between groups at any study period. Locognosia was significantly better at 1.5 and 3 years in group SR; locognosia was excellent in 17 patients of group SR vs 5 patients of group R at 1.5-year follow-up and in 14 patients of group SR vs 5 patients of group R at 3-year follow-up. Locognosia was not different between the study groups at 6-year follow-up.

CONCLUSION

A 2-stage home program of SR improved locognosia at 1.5 and 3 years after low-median nerve complete transection and repair without significant differences in other modalities or the 6-year follow-up of a small subsample.

Characterization of Hand Tendons Through High-Frequency Ultrasound Elastography

Tendon stiffness plays an important role in the tendon healing process, and many studies have indicated that measuring the shear wave velocity (SWV) on tendons relates to their stiffness. Because the thickness of hand tendons is a few millimeters, high-resolution imaging is required for visualizing hand tissues. However, the resolution of current ultrasound elastography systems is insufficient. In this study, a high-frequency (HF) ultrasound elastography system is proposed for measuring the SWVs of hand tendons. The HF ultrasound elastography system uses an external vibrator to create shear waves on hand tendons. Then, it uses a 40-MHz HF ultrasound array transducer with ultrafast ultrasound imaging technology to measure the SWV for characterizing hand tendons. A handheld device that combines a transducer and a vibrator allows the user to scan hand tissues. The biases of HF ultrasound elastography were measured in gelatin phantom experiments and were less than 6% compared to standard mechanical testing approach. Human experiments showed the ability to use HF ultrasound elastography to distinguish different SWVs of hand tendons. The SWVs were 0.73 ± 0.65 m/s and 1 ± 0.54 m/s for flexor digitorum superficialis (FDS) and flexor digitorum profundus (FDP), respectively, and 0.52 ± 0.14 m/s and 4.02 ± 0.77 m/s for extensor tendon under stretch and contraction conditions, respectively. The simplicity and convenience of the HF ultrasound elastography system for measuring hand tendon stiffness make it a promising tool for evaluating the severity of hand injuries and the performance of rehabilitation after hand injuries.

Patient satisfaction after treatment of distal radial fractures in older adults

The Wrist and Radius Injury Surgical Trial (WRIST) collaboration is the largest clinical trial ever conducted in hand surgery. We applied data from this study to examine the relationship between functional outcomes and patient satisfaction after treatment of distal radial fractures. Patients aged 60 years and older with isolated distal radial fractures were enrolled at 24 health systems. Grip strength and the arc of wrist motion were measured after treatment. The Michigan Hand Outcomes Questionnaire was used to measure patient satisfaction. Receiver operating characteristic curves were created using patient satisfaction as the reference standard and each functional measure as a predictor. At 12 months after treatment, mean grip strength was 82% of normal and mean arc of motion was 88% of normal. The optimal cut-off points to distinguish satisfaction from dissatisfaction occurred when patients recovered 59% of hand strength and 79% of wrist motion. Continuing therapy to increase functional gains beyond this point unnecessarily utilizes healthcare resources without additional patient-reported gains. Level of evidence: IV.

Participants’ perceptions of Kinesio tape for carpal tunnel syndrome: A qualitative study

Introduction

Kinesio tape is an alternative non-surgical treatment approach for addressing symptoms of carpal tunnel syndrome. The purpose of the study was to investigate individuals’ experiences with the dorsal application of Kinesio tape for carpal tunnel syndrome management and its impact on pain and function.

Method

The study design was a limited phenomenological design study embedded in a randomized controlled trial. Daily symptom journals and semi-structured interviews were completed with 15 participants who were purposefully recruited and randomly allocated to the intervention group of a single blind randomized controlled trial. Kinesio tape was applied dorsally on the affected forearm, wrist, and digits for a duration of two weeks. Transcribed data were analyzed using descriptive coding, coding schemes, and frequency charts to identify emerging themes.

Results

Three themes emerged: Kinesio tape was positively perceived to be effective on decreasing pain, increasing self-efficacy, and improving daily functional performance on tasks previously avoided or abandoned. The most common problem identified was maintaining Kinesio tape on the hands and fingers, to which the majority of participants expressed a desire to learn application.

Discussion

Results of this study suggest that Kinesio tape is a positively perceived intervention for decreasing pain and increasing function for individuals with carpal tunnel syndrome and warrants further consideration as an alternative conservative intervention for carpal tunnel syndrome.

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.

Enabling Work: Occupational Therapy Interventions for Persons with Occupational Injuries and Diseases: A Scoping Review

Purpose This review aims to map the scope of published research on occupational therapy (OT) interventions and pertinent work and work-related outcomes for persons with occupational injuries and diseases. Methods The scoping review adapted Arksey and O'Malley's framework. Six electronic databases were searched. Ancestral search was also done on five systematic reviews. The search was conducted from September 2015 to October 2015. Interventions and outcomes were coded using the International Classification of Functioning, Disability and Health Core Set for Vocational Rehabilitation to plot trends. Results Forty-six articles were included in the review. The top five intervention approaches included: acquiring skills (12.27%), health services, systems, and policies (10.43%), products and technology for employment (9.20%), handling stress and other psychological demands (7.98%), and apprenticeship (6.74%). The top five outcomes targeted included: remunerative employment (15.71%); sensation of pain (10.99%); emotional functions (5.76%); handling stress and other psychological demands (5.76%); economic self-sufficiency (4.71%); muscle endurance functions (4.71%); exercise tolerance functions (4.71%); undertaking multiple tasks (4.19%); acquiring, keeping, and terminating a job (4.19%); and looking after one's health (4.19%). Conclusion The trend in interventions show the use of activities and environment facilitators which are attuned to the conceptual nature of OT. Furthermore, the trend in outcomes show that there is substantial evidence that supports the use of OT to target work. This review may provide a platform for collaboration with other professionals and also help identify research directions to strengthen the evidence base for OT in work-related practice.

Perceptions of Existing Wearable Robotic Devices for Upper Extremity and Suggestions for Their Development: Findings From Therapists and People With Stroke

Background

Advances in wearable robotic technologies have increased the potential of these devices for rehabilitation and as assistive devices. However, the utilization of these devices is still limited and there are questions regarding how well these devices address users’ (therapists and patients) needs.

Objective

The aims of this study were to (1) describe users’ perceptions about existing wearable robotic devices for the upper extremity; (2) identify if there is a need to develop new devices for the upper extremity and the desired features; and (3) explore obstacles that would influence the utilization of these new devices.

Methods

Focus groups were held to collect data. Data were analyzed thematically.

Results

A total of 16 participants took part in the focus group discussions. Our analysis identified three main themes: (1) “They exist, but...” described participants’ perceptions about existing devices for upper extremity; (2) “Indeed, we need more, can we have it all?” reflected participants’ desire to have new devices for the upper extremity and revealed heterogeneity among different participants; and (3) “Bumps on the road” identified challenges that the participants felt needed to be taken into consideration during the development of these devices.

Conclusions

This study resonates with previous research that has highlighted the importance of involving end users in the design process. The study suggests that having a single solution for stroke rehabilitation or assistance could be challenging or even impossible, and thus, engineers should clearly identify the targeted stroke population needs before the design of any device for the upper extremity.

SPOTS: A Model for the Creation of Sustainable, Population-Based, Occupational Therapy Fieldwork Sites

This paper describes a model for the creation of sustainable, population-based, occupational therapy fieldwork sites (SPOTS). An example of a population-based fieldwork site was created with Appalachian Mountain People in Kentucky and its outcomes are presented. Outcomes were gathered using a wide variety of evaluation feedback forms. The results indicate that all staff, student, and college feedback were extremely favorable as detailed and suggest that others may use the SPOTS Model to develop population-based occupational therapy services that address public health issues for people with disabilities identified in Healthy People 2020 and create scholarly opportunities for students and faculty.

Effectiveness of Occupational Therapy Interventions for Adults With Musculoskeletal Conditions of the Forearm, Wrist, and Hand: A Systematic Review

Occupational therapy practitioners are key health care providers for people with musculoskeletal disorders of the distal upper extremity. It is imperative that practitioners understand the most effective and efficient means for remediating impairments and supporting clients in progressing to independence in purposeful occupations. This systematic review provides an update to a previous review by summarizing articles published between 2006 and July 2014 related to the focused question, What is the evidence for the effect of occupational therapy interventions on functional outcomes for adults with musculoskeletal disorders of the forearm, wrist, and hand? A total of 59 articles were reviewed. Evidence for interventions was synthesized by condition within bone, joint, and general hand disorders; peripheral nerve disorders; and tendon disorders. The strongest evidence supports postsurgical early active motion protocols and splinting for various conditions. Very few studies have examined occupation-based interventions. Implications for occupational therapy practice and research are provided.

Current Evidence and Opportunities for Expanding the Role of Occupational Therapy for Adults With Musculoskeletal Conditions

Musculoskeletal conditions are the second greatest cause of disability worldwide, and chronic musculoskeletal conditions affect nearly the same percentage of the general population as chronic circulatory and respiratory conditions combined. Moreover, people with musculoskeletal conditions experience a significant decline in independence with daily activities and occupational performance, key areas targeted by occupational therapy interventions. This special issue of the American Journal of Occupational Therapy provides comprehensive summaries of evidence for the care of common musculoskeletal conditions, highlights important implications that support evidence-informed practice, and proposes ways to advance the practice of occupational therapy to improve the lives of people with musculoskeletal conditions.

A Novel Adhesion Index for Verifying the Extent of Adhesion for the Extensor Digitorum Communis in Patients with Metacarpal Fractures

This study aims to determine if the relative displacement between the extensor digitorum communis (EDC) tendon and its surrounding tissues can be used as an adhesion index (AI) for assessing adhesion in metacarpal fractures by comparing two clinical measures, namely single-digit-force and extensor lag (i.e., the difference between passive extension and full active extension). The Fisher–Tippett block-matching method and a Kalman-filter algorithm were used to determine the relative displacements in 39 healthy subjects and 8 patients with metacarpal fractures. A goniometer was used to measure the extensor lag, and a force sensor was used to measure the single-digit-force. Measurements were obtained twice for each patient to evaluate the performance of the AI in assessing the progress of rehabilitation. The Pearson correlation coefficient was calculated to quantify the various correlations between the AI, extensor lag, and single-digit-force. The results showed strong correlations between the AI and the extensor lag, the AI and the single-digit-force, and the extensor lag and the single-digit-force (r = 0.718, −0.849, and −0.741; P = 0.002, P < 0.001, and P = 0.001, respectively). The AI in the patients gradually decreased after continuous rehabilitation, but remained higher than that of healthy participants.

Introducing purposeful activity kits in a hand rehabilitation practice: Effects on clinical practice patterns and job satisfaction among occupational therapy practitioners

Introduction

Facilitating function through occupation and purposeful activity is the basic tenet of occupational therapy. However, the majority of research in hand rehabilitation clinics continues to focus on biomechanical interventions. The purpose of this research was to study practice patterns and personal opinions of occupational therapy practitioners before and after providing purposeful activity kits to an outpatient occupational therapy hand clinic.

Methods

Mixed-method design to evaluate an 8-week intervention of providing purposeful activity kits to a busy, military outpatient hand clinic. A paper survey was administered to nine occupational therapy practitioners before and after the intervention. Qualitative data were gathered through semi-structured interviews.

Results

A descriptive analysis indicated an increase in the use of activities, crafts, and occupation after the introduction of the purposeful activity kits. Practitioners consistently reported time as the top factor in their inability to incorporate more purposeful activities. Qualitative results support use of the new activities during both intervention and evaluation due to the focus on function and ease of use of the kits.

Conclusion

Purposeful activities can enhance any rehabilitation clinic in an organized, cost-effective manner. Practitioners responded positively toward the added equipment; however, it will take time and effort to adjust the theoretical decision making of practitioners. Additional participants and length of intervention is needed.

The effect of an occupation-based intervention in patients with hand-related disorders grouped using the sense of coherence scale: Study protocol

Introduction

High-quality rehabilitation is required if patients with hand-related disorders are to achieve high levels of functioning. Occupation-based interventions are effective in stroke, hip fractures, and for elderly people, but there is limited knowledge of their effect in hand therapy. Sense of coherence may affect rehabilitation outcome, since patients with weak sense of coherence experience lower functioning, are less satisfied with their occupational performance, have inferior quality of life and more pain compared to patients with stronger sense of coherence .

Method

Following SPIRIT guidelines, we present a randomized, controlled, parallel-grouped trial. It investigates the effect of an occupation-based intervention for outpatients with hand-related disorders and whether sense of coherence influences the outcomes. Patients are stratified into three groups (weak, medium and strong sense of coherence) and randomized to occupation-based or exercise-based hand therapy. Sample size calculation indicates that 70 patients are required in each intervention in each separate sense of coherence group. With an expected drop-out of 20%, a total of 504 participants will be randomized. Primary analysis is score change in functioning measured by the Disabilities of the Arm, Shoulder and Hand from start of rehabilitation to three months’ follow-up. Secondary outcomes are self-evaluated occupational performance and satisfaction with occupational performance.

Conclusion

This study will add valuable knowledge to the field of hand therapy regarding the therapeutic use of occupations that patients find meaningful. Moreover, it may show which patients will benefit the most from an occupation-based intervention in relation to their sense of coherence.

Application of a novel Kalman filter based block matching method to ultrasound images for hand tendon displacement estimation

PURPOSE

Information about tendon displacement is important for allowing clinicians to not only quantify preoperative tendon injuries but also to identify any adhesive scaring between tendon and adjacent tissue. The Fisher-Tippett (FT) similarity measure has recently been shown to be more accurate than the Laplacian sum of absolute differences (SAD) and Gaussian sum of squared differences (SSD) similarity measures for tracking tendon displacement in ultrasound B-mode images. However, all of these similarity measures can easily be influenced by the quality of the ultrasound image, particularly its signal-to-noise ratio. Ultrasound images of injured hands are unfortunately often of poor quality due to the presence of adhesive scars. The present study investigated a novel Kalman-filter scheme for overcoming this problem.

METHODS

Three state-of-the-art tracking methods (FT, SAD, and SSD) were used to track the displacements of phantom and cadaver tendons, while FT was used to track human tendons. These three tracking methods were combined individually with the proposed Kalman-filter (K1) scheme and another Kalman-filter scheme used in a previous study to optimize the displacement trajectories of the phantom and cadaver tendons. The motion of the human extensor digitorum communis tendon was measured in the present study using the FT-K1 scheme.

RESULTS

The experimental results indicated that SSD exhibited better accuracy in the phantom experiments, whereas FT exhibited better performance for tracking real tendon motion in the cadaver experiments. All three tracking methods were influenced by the signal-to-noise ratio of the images. On the other hand, the K1 scheme was able to optimize the tracking trajectory of displacement in all experiments, even from a location with a poor image quality. The human experimental data indicated that the normal tendons were displaced more than the injured tendons, and that the motion ability of the injured tendon was restored after appropriate rehabilitation sessions.

CONCLUSIONS

The obtained results show the potential for applying the proposed FT-K1 method in clinical applications for evaluating the tendon injury level after metacarpal fractures and assessing the recovery of an injured tendon during rehabilitation.

Upper-Limb Rehabilitation With Adaptive Video Games for Preschool Children With Developmental Disabilities

OBJECTIVE

This study used a novel device to make video games accessible to children with developmental disabilities (DD) by modifying the training software and interfaces to enhance motor training.

METHOD

In the pretest-posttest design, 20 children (13 boys, 7 girls; mean age=5.2 yr) with DD received adaptive upper-limb motor rehabilitation consisting of fifteen 30-min individual sessions 3 times per week for 5 wk.

RESULTS

Improvement in Beery-Buktenica Developmental Test of Visual Motor Integration and Peabody Developmental Motor Scales, Second Edition, scores for children with DD indicated significant differences between pretest and posttest.

CONCLUSION

The rehabilitation device modified for the needs of children with DD is effective in improving visual-motor performance of children with DD.

Variation in the Use of Therapy following Distal Radius Fractures in the United States

Background:

Distal radius fractures (DRFs) are one of the most common injuries among the elderly, resulting in significant expense and disability. The specific aims of this study are (1) to examine rates of therapy following DRFs and (2) to identify those factors that influence utilization of therapy and time span between DRF treatment and therapy among a national cohort of elderly patients.

Methods:

We examined national use of physical and occupational therapy among all Medicare beneficiaries who suffered DRFs between January 1, 2007, and October 1, 2007, and assessed the effect of treatment, patient-related, and surgeon-related factors on utilization of therapy.

Results:

Overall, 20.6% of patients received either physical or occupational therapy following DRF. Use of therapy varied by DRF treatment, and patients who underwent open reduction and internal fixation were more likely to receive therapy compared with patients who received closed reduction. Patients who received open reduction and internal fixation were also referred to therapy earlier compared with patients who received external fixation, percutaneous pinning, and closed reduction. Surgeon specialization is associated with greater use of postoperative therapy. Patient predictors of therapy use include younger age, female sex, higher socioeconomic status, and fewer comorbidity conditions.

Conclusion:

Use of therapy following DRF varies significantly by both patient- and surgeon-related factors. Identifying patients who benefit from postinjury therapy can allow for better resource utilization following these common injuries.
