Effects of rehabilitative interventions on pain, function and physical impairments in people with hand osteoarthritis: a systematic review

The Effectiveness of Exercise-Based Rehabilitation in People With Hand Osteoarthritis: A Systematic Review With Meta-analysis

OBJECTIVE: To investigate the effectiveness of exercise-based rehabilitation programs compared with nonexercise intervention or no intervention for people with hand osteoarthritis (OA). DESIGN: Intervention systematic review with meta-analysis. LITERATURE SEARCH: We searched 5 databases on July 23, 2023. STUDY SELECTION CRITERIA: We included randomized controlled trials that compared the effectiveness of rehabilitation programs that included an exercise component, with nonexercise intervention or no intervention for people with hand OA. DATA SYNTHESIS: Standardized mean differences (SMDs) were pooled using a random-effects model. The risk of bias was assessed using the Cochrane Risk of Bias 2.0 tool. The certainty of the evidence was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach. RESULTS: Fourteen trials were included in the meta-analysis (n = 1341 participants). In the immediate term (<24 weeks), there was low-certainty evidence of an effect of exercise-based rehabilitation on improving pain (13 trials; SMD = -0.65; 95% CI: -1.06, -0.25), function (11 trials; SMD = -0.35; 95% CI: -0.54, -0.15), and grip strength (14 trials; SMD = 0.21; 95% CI: 0.03, 0.38). There was moderate-certainty evidence of an effect on reducing stiffness (7 trials; SMD = -0.33; 95% CI: -0.51, -0.16). There was low-certainty evidence of no effect on improving pinch strength and quality of life. For the long term (≥24 weeks), there was low-certainty evidence that exercise-based rehabilitation had no additional effect on improving pain, function, and stiffness. CONCLUSION: Exercise-based rehabilitation improved pain, function, stiffness, and grip strength in people with hand OA in the immediate term; the benefits were not maintained in the long term.

Short-term clinical outcomes of transarterial embolization for symptomatic hand osteoarthritis refractory to conservative treatment

PURPOSE

The present study aims to assess the short-term clinical outcomes and safety of transarterial embolization (TAE) for symptomatic hand osteoarthritis (OA) refractory to conservative treatment.

METHODS

The present retrospective cohort pilot study included nine patients who underwent TAE for symptomatic OA-associated hand pain in a single tertiary center between November 2022 and January 2023. The baseline and post-procedural OA-associated hand pain and function were assessed using the visual analog scale (VAS) and the Australian Canadian Hand Osteoarthritis Index (AUSCAN). The use of conservative treatment and pain medications was also recorded. Post-procedural adverse events were evaluated according to the Society of Interventional Radiology classification.

RESULTS

Compared with the baseline, the overall VAS scores were significantly decreased at 1-week, 1-month, 3-months, and 6-months after TAE (76 ± 15 mm versus 34 ± 18 mm, P < 0.001; 32 ± 11 mm, P < 0.001; 21 ± 15 mm, P < 0.001; 18 ± 19 mm, P = 0.002). Similarly, improvement in the mean total AUSCAN scores (22.0 ± 10.0 versus 13.2 ± 6.6, P = 0.007; 14.11 ± 7.3, P = 0.004; 9.8 ± 6.8, P = 0.004; 9.3 ± 7.4, P = 0.011) were documented. The use of other conservative treatment methods also gradually decreased. There were no severe adverse events reported during the follow-up period.

CONCLUSION

TAE is a feasible and safe treatment method for symptomatic hand OA refractory to conservative treatment. This minimally invasive procedure effectively relieves debilitating OA-associated joint pain and restores hand function with a durable treatment effect.

Complex motions embedded in a hand exercise regimen - effects on thumb function in participants with carpometacarpal osteoarthritis: A pilot study

Objective

The goal of this pilot study was to identify changes associated with completion of a unique six-week hand exercise program in persons with carpometacarpal osteoarthritis.

Methods

Twenty-four individuals, aged 55-80, with doctor-diagnosed carpometacarpal osteoarthritis participated in the study. Movement data from standard clinical motions and complex multi-planar motions were obtained using a motion capture system at three-time points: an initial visit, after two weeks of hand exercises, and after completion of the six-week exercise program.

Results

This exercise program produced trends of improvement in complex multi-planar motions. Specifically, joint angle changes were seen during opposition and the formation of an "okay sign" that was included as part of the exercise program.

Conclusion

Through the use of motion capture, changes were identified in thumb joint function after exercise. Specifically, motions associated with the more complex multi-planar tasks showed changes in individual joint contributions following the six-week exercise intervention. The results suggest that further exploration of this exercise program, particularly the inclusion of complex multi-planar tasks during osteoarthritis treatment and associated evaluations, should be considered in future clinical studies.

Reduced pain and improved daily activities for individuals with hand osteoarthritis using a silicone wrist hand orthosis

BACKGROUND

Symptoms of hand osteoarthritis (OA), such as pain, reduced grip strength, loss of range of motion (ROM) and joint stiffness, can lead to impaired hand function and difficulty with daily activities. Rehabilitative interventions with orthoses are commonly in the treatment of hand OA to reduce pain, improve hand strength and ROM, provide support for improved function and help with joint stability.

PURPOSE

The objectives of this perception-based study were to evaluate the effect of a silicone wrist hand orthoses (SWHO) on pain and daily functioning.

STUDY DESIGN

This study is a qualitative descriptive study. The patient received outcome (PRO) questions in the study were based on the Patient Rated Wrist and/or Hand Evaluation (PRWHE), a 15-item questionnaire designed to measure wrist pain and disability in activities of daily living.

METHODS

Patients with OA using a SWHO were asked to complete a questionnaire about the effectiveness of the brace after wearing it for 3 weeks. Primary outcome measure was general daily functioning with and without the use of the SWHO. Secondary outcome measures were change in pain symptoms and limitations for certain activities with and without the aid.

RESULTS

The results of this large-scale PROM study of 551 patients on the effectiveness of SWHOs in patients with hand OA show an improvement in overall daily functioning of 77% and a 61% reduction in perceived pain. This study adds to the evidence reported by systematic reviews of conservative interventions for hand OA and further quantifies the effects of a tailor made SWHO. This study confirms that wearing a wrist orthosis has a particularly significant impact on the execution of static and repetitive wrist-straining activities.

CONCLUSION

The study on the effectiveness of a SWHO in patients with hand OA shows that the use of a SWHO contributes to general daily function, reduces pain and increases the breadth of potential daily activities. This study shows that the use of a SWHO appears to offer pain relief and suitable support to the joint.

The effects of a mobile app-delivered intervention in people with symptomatic hand osteoarthritis: a pragmatic randomized controlled trial

BACKGROUND

Exercise therapy, self-management and education are recommended interventions for hand osteoarthritis (OA), but new delivery systems are needed to solve lack of adherence.

AIM

To determine the effects on hand function and pain related measures of a mobile app-delivered intervention, compared with usual care, in patients with symptomatic hand OA.

DESIGN

A pragmatic, multicenter, two-group parallel randomized controlled trial.

SETTING

Community health centers in rural southern Spain.

POPULATION

Eighty-three participants with unilateral or bilateral symptomatic hand OA were proposed to participate, and finally 74 were included and randomized.

METHODS

Participants received a home multimodal treatment (exercise, education, and self-management recommendations) with the CareHand mobile app or usual care (written exercises) over 12 weeks. Monthly telephone calls were performed to monitor adherence. The primary outcome was hand physical function (Australian/Canadian Hand Osteoarthritis Index, AUSCAN) at 3- and 6-months. Secondary measures included hand pain intensity and morning stiffness, upper limb function, hand dexterity, and grip and pinch strength.

RESULTS

The CareHand group showed significant within-group changes in hand function at 6-months (-3.0, 95% CI -5.1 to -0.9 vs. usual care: -0.9, 95% CI -3.3 to 1.5). Neither group showed improvements in hand function at 3-months (CareHand: -1.5, 95% CI -3.1 to 0.1; usual care: -0.5, 95% CI -2.7 to 1.7). For the secondary outcomes, the CareHand group showed better results on upper limb function both at 3- and 6-months, and on pain both at 1- and 3-months compared to usual care group. Linear regression models indicated that baseline scores of pain intensity, hand status, and upper limb function were associated with a greater improvement in hand pain and physical function.

CONCLUSIONS

A mobile app-delivered intervention is effective for improving hand function, and better than usual care for upper limb function and pain. Further research is warranted to understand the impact of mobile health (mHealth) in people with hand OA.

CLINICAL REHABILITATION IMPACT

mHealth interventions are a feasible and secure multimodal delivery approach in older adults with hand OA in rural primary care setting. Baseline pain and upper limb function might predict functional hand outcomes.

The effects of motor imagery on trapeziometacarpal osteoarthritis in women during the post-surgical immobilisation period: A protocol for a randomised clinical trial

Background:

Trapeziometacarpal osteoarthritis is the second most frequent degenerative hand disease and is the most functionally debilitating. The condition presents in 66% of women over 55. Motor imagery (MI) training post-surgery could help reduce rehabilitation times.

Method:

It is an experimental, prospective, longitudinal, parallel arm randomised clinical trial. Participants were women over 50 years old on the surgical waiting list. The experimental group will undergo MI training during the 3-week post-surgical immobilisation period. The control group will receive standard rehabilitation treatment. Outcomes will be assessed four times throughout the study using the Disabilities of the Arm, Shoulder and Hand questionnaire, the Cochin Hand Function Scale questionnaire, the Visual Analogue Scale, goniometry, baseline pinch gauge, circumferential measurement (cm), the Modified Kapandji Index and the Kinaesthetic and Visual Imagery questionnaire.

Discussion:

Early MI could improve hand function leading to improvements in recovery times.

Trial registration:

Clinical Trials registration: NCT03815734. Ethics Committee approval: 17155. Project funded in 2021.

(Re-)Defining ergonomics in hand therapy: Applications for the management of upper extremity osteoarthritis

STUDY DESIGN

Invited literature review BACKGROUND: Arthritis is the leading cause of disability in adults, and research shows that people living with arthritis experience work instability, loss of independence, financial difficulties, and overall decreased quality of life. Current nonpharmacological treatments can be beneficial for short term relief; however, the evidence on these long-term treatments is limited. Ergonomic modifications have been used in the workplace to address musculoskeletal conditions to ensure proper fit of one's environment, and research shows that these modifications can decrease pain and injury and increase work productivity. A broader perspective on ergonomic approaches may be important to supporting individuals with arthritis within hand therapy.

PURPOSE OF THE STUDY

This review proposes an expanded perspective on ergonomic approaches within hand therapy and explores published literature to identify potential benefits of applying ergonomic approaches for individuals with upper extremity arthritis.

METHODS

A systematic search and screening process was conducted to identify articles that implemented an ergonomic approach for the support of individuals with upper extremity osteoarthritis or rheumatoid arthritis.

RESULTS

A total of 34 articles described interventions that employed ergonomics including task-based or general ergonomics (n = 17), contextualized supports (n = 8), or holistic, lifestyle approaches (n = 9). Only one study focused solely on individuals with osteoarthritis, whereas interventions for individuals with rheumatoid arthritis showed positive outcomes across these categories. Situational learning, building of patient self-efficacy, and development of new habits and routines are vital for carryover and implementation to support performance in daily life.

CONCLUSION

There is an opportunity for hand therapists to extend the scope of interventions provided as part of an ergonomic approach to supporting patients. Specifically, therapists can consider use of emerging technologies and telehealth that promote contextualization and follow-up for long-term outcomes.

Effects of a progressive resistance exercise program in patients with hand osteoarthritis: A randomized, controlled trial with a blinded assessor

OBJECTIVE

To assess the effectiveness of a progressive resistance strength program on pain, function and strength in hand osteoarthritis patients.

DESIGN

Randomized controlled trial.

SETTINGS

Outpatients, University Hospital.

SUBJECTS

Sixty hand osteoarthritis patients were randomly allocated to exercise group (n = 30) or control group (n = 30).

INTERVENTION

The exercise group performed a progressive resistance strength program for hand muscles over 12 weeks. Both groups had a single education session.

MAIN MEASURES

The primary outcome was pain intensity (numeric pain scale). The secondary outcomes were - AUSCAN Hand Osteoarthritis Index, Cochin Hand Functional Scale for function and grip and pinch strength. A blinded evaluator performed the evaluations at baseline, 6 and 12 weeks.

RESULTS

The mean age were 68.9 (8.8) and 64.7 (8.9) for control and exercise groups, respectively. No significant differences between-group was observed for pain after 12 weeks (mean difference between groups was -1.30 (-0.02 to 2.62) for dominant hand and -1.33 (0.01-2.65) for non-dominant hand at T12, with P = 0.085 and 0.295, respectively). Regarding secondary outcomes, statistically significant differences between groups were found in exercise group: AUSCAN index - total score (P = 0.005), pain (P = 0.006), function (P = 0.047), and Cochin scale (P = 0.042) with the following mean difference between groups: -9.9 (4.07-15.73), -3.26 (1.06-5.46), -5.03 (1.20-8.86), and -6.27 (0.18-12.36), respectively.

CONCLUSION

No difference was observed for pain (numerical pain scale) after the progressive resistance exercise program performed, however in exercise group, an improvement was observed on secondary outcomes such as pain during activities and function for patients with hand osteoarthritis.

The effects of an 8-week knitting program on osteoarthritis symptoms in elderly women: A pilot randomized controlled trial

BACKGROUND

Exercise therapy is effective in reducing symptoms and disability associated with hand osteoarthritis (HOA) but often has low adherence. An intervention consisting in a meaningful occupation, such as knitting, may improve adherence to treatment. This pilot randomized controlled trial (RCT) studied the adherence and clinical effectiveness of a knitting program in older females suffering from HOA to evaluate the acceptability of this intervention and assess the feasibility of a larger-scale RCT.

METHODS

Single-blind, two-arm pilot RCT with a parallel group design with 37 participants (18 control, 19 intervention). Control participants were given an educational pamphlet and assigned to a waiting list. The knitting program (8-week duration) had two components: bi-weekly 20-min group knitting sessions and daily 20-min home knitting session on the 5 remaining weekdays. Measures included knitting adherence (implementation outcomes) as well as stiffness, pain, functional status, hand physical activity level, patient's global impression of change, health-related quality of life, self-efficacy, and grip strength (clinical outcomes measured throughout the 8-week program and 4 weeks after the intervention).

RESULTS

Our protocol is feasible and the intervention was acceptable and enjoyable for participants, who showed high adherence. No difference was observed between the two groups for any of the clinical outcome measures (all p > .05).

CONCLUSION

Knitting is a safe and accessible activity for older women with HOA. However, our 8-week knitting program did not result in improvements in any of our outcome measures. Knitting for a longer period and/or with higher frequency may yield better outcomes.

Initial stages of hand osteoarthritis do not affect the extrinsic muscles of the hand: a cross-sectional study

The objective of this study was to verify whether women in the initial stages of hand osteoarthritis (HOA) already have impaired grip strength and flexor and extensor torque of the wrist compared to healthy women. It also aimed to correlate these variables with pain, stiffness, and function of the hand. Twenty-six women were divided into a control group [CG, n = 13; 56 (51–61) years old] and a hand osteoarthritis group [HOAG, n = 13; 58 (53–63) years old]. Grades II and III were included in the HOA group according to the criteria of Kellgren and Lawrence. All volunteers answered an initial assessment form, the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire and the Australian/Canadian Hand Osteoarthritis Index (AUSCAN). The grip strength and isometric wrist flexor and extensor torque were evaluated by a hydraulic dynamometer. Comparisons between groups used Student’s t test for independent samples and the Mann–Whitney test. Spearman's correlation was used to correlate grip strength and flexor and extensor wrist torque to the degree of disease and DASH and AUSCAN scores. There were no differences between the groups in grip strength or flexor and extensor torque values. In terms of the DASH and the AUSCAN, the HOA group had higher scores, indicating worse hand function. A strong negative correlation was found between grip strength and the degree of HOA (r =  − 0.70, p = 0.008), and a moderate positive correlation was found between flexor torque and the degree of HOA (r = 0.53, p = 0.05). The pain (r =  − 0.61, p = 0.02) and function (r =  − 0.66, p = 0.01) sections of the AUSCAN correlated negatively with grip strength. Pain can be an important feature in the HOA rehabilitation process, as it can influence handgrip strength and function. It is important that rehabilitation is implemented as soon as possible to guarantee the maintenance of strength and function since with the severity of the disease, patients tend to have deficits in grip strength and function.

Does blood flow restriction training enhance clinical outcomes in knee osteoarthritis: A systematic review and meta-analysis

OBJECTIVE

To systematically review the efficacy of blood flow restriction training (BFRT) on individuals with knee osteoarthritis (OA).

DESIGN

Systematic review with meta-analysis.

LITERATURE SEARCH

Eight electronic databases were searched by one researcher.

STUDY SELECTION CRITERIA

Randomised clinical trials (RCTs) comparing BFRT to regular resistance training (RT) for knee OA.

DATA SYNTHESIS

One reviewer selected the eligible RCTs and exported the data. Two reviewers evaluated study quality using the PEDro scale. We performed meta-analysis where appropriate using a random-effects model. We rated the quality of evidence using GRADE.

RESULTS

Five studies were eligible. The key outcomes analysed were pain, self-reported function, objective physical function, strength and muscle size. Across all comparisons, there was low to moderate quality evidence of no difference between BFRT and traditional RT.

CONCLUSION

The limited available evidence does not suggest that BFRT enhances outcomes for people with knee OA. These findings do not support clinicians using BFRT in people with knee OA. Instead, evidence-based messages regarding exercise and education should remain the mainstay of rehabilitation. Additional studies should clarify whether some people with knee OA who cannot complete an adequate exercise programme due to pain, might still benefit from BFRT to facilitate less painful exercise.

Joint Protection Programmes for People with Osteoarthritis and Rheumatoid Arthritis of the Hand: An Overview of Systematic Reviews

Purpose: Joint protection has been introduced as a self-management strategy for people with rheumatoid arthritis (RA) and osteoarthritis (OA) of the hand. The purpose of this study was to conduct an overview of systematic reviews (SRs) and critically appraise the evidence to establish the current effectiveness of joint protection for people with hand RA and OA. Method: A comprehensive search was conducted of six databases from January 2008 to May 2018. SRs that evaluated the effectiveness of joint protection for people with hand arthritis were eligible for inclusion. The A MeaSurement Tool to Assess systematic Reviews (AMSTAR) 2 checklist was used to assess the methodological quality of each SR. Results: Nine SRs were included: two were rated as high quality, and seven were rated as low quality. Seven of the nine did not take into account risk of bias when interpreting or discussing their findings, six did not assess publication bias, and five did not register their protocol. The high-quality reviews found no clinically important benefit of joint protection for pain, hand function, and grip strength levels. The low-quality reviews reported improvements in function, pain, grip strength, fatigue, depression, self-efficacy, joint protection behaviours, and disease symptoms in people with RA. Conclusions: High-quality evidence from high-quality reviews found a lack of any clinically important benefit of joint protection programmes for pain, hand function, and grip strength outcomes, whereas low-quality evidence from low-quality reviews found improvements in these outcomes.

Determining Isolated Thumb Forces in Osteoarthritic and Healthy Persons

Carpometacarpal (CMC) osteoarthritis (OA) can dramatically impair thumb function resulting in the inability to complete basic tasks. Development of a method to detect thumb forces changes is essential to understand of the progression of carpometacarpal osteoarthritis and the effects of treatment. The goals of this study were to (1) develop a method to measure thumb forces in multiple directions, (2) perform an initial demonstration of this method on three populations, young healthy (YH), older healthy (OH), and older participants with carpometacarpal osteoarthritis, and (3) determine the effects of short-term exercises on thumb force production in these pilot groups. A multi-axis load cell with a custom-built apparatus and a hand grip dynamometer were used to measure thumb and grip forces. Forces were collected in four directions: radial abduction and adduction, and palmar abduction and adduction. All participants completed thumb and grip testing prior to (week 0), during (week 2), and following (week 6), a hand exercise regimen. Group differences and the effects of exercise on force production were determined. Hand exercises improved thumb forces in young healthy female participants during radial (p = 0.017) and palmar abduction (p = 0.031) and female participants with osteoarthritis during palmar abduction (p = 0.010). Exercise improved grip strength in young healthy males (p = 0.028), young healthy females (p = 0.041), and females with osteoarthritis (p = 0.027). This research demonstrates the successful use of a new device to determine isolated thumb forces, and its clinical utility to identify changes after a short exercise regimen.

The effectiveness of joint-protection programs on pain, hand function, and grip strength levels in patients with hand arthritis: A systematic review and meta-analysis

STUDY DESIGN

Systematic review with meta-analysis.

INTRODUCTION

Joint protection (JP) has been developed as a self-management intervention to assist people with hand arthritis to improve occupational performance and minimize joint deterioration over time.

PURPOSE OF THE STUDY

We examined the effectiveness between JP and usual care/control on pain, hand function, and grip strength levels for people with hand osteoarthritis and rheumatoid arthritis.

METHODS

A search was performed in 5 databases from January 1990 to February 2017. Two independent assessors applied Cochrane's risk of bias tool, and a Grading of Recommendations Assessement, Development and Evaluation (GRADE) approach was adopted.

RESULTS

For pain levels at short term, we found similar effects between JP and control standardized mean difference (SMD; -0.00, 95% confidence interval [CI]: -0.42 to 0.42, I² = 49%), and at midterm and long-term follow-up, JP was favored over usual care SMD (-0.32, 95% CI: -0.53 to -0.11, I² = 0) and SMD (-0.27, 95% CI: -0.41 to -0.12, I² = 9%), respectively. For function levels at midterm and long-term follow-up, JP was favored over usual care SMD (-0.49, 95% CI: -0.75 to -0.22, I² = 34%) and SMD (-0.31, 95% CI: -0.50 to -0.11, I² = 56%), respectively. For grip strength levels, at long term, JP was inferior over usual care mean difference (0.93, 95% CI: -0.74 to 2.61, I² = 0%).

CONCLUSIONS

Evidence of very low to low quality indicates that the effects of JP programs compared with usual care/control on pain and hand function are too small to be clinically important at short-, intermediate-, and long-term follow-ups for people with hand arthritis.

Effect of Kinesio Taping on Pain, Range of Motion, Hand Strength, and Functional Abilities in Patients with Hand Osteoarthritis: A Pilot Randomized Clinical Trial

BACKGROUND

Osteoarthritis is one of the most prevalent joint diseases in older adults. Since hands play a key role in daily activities, their impairment causes disability and reduction of independency. The present study aimed to investigate the effect of using Kinesio tape on pain, range of motion (ROM), hand strength, and functional abilities in patient with hand osteoarthritis (HOA).

METHODS

In this randomized clinical trial study, 38 patients with the diagnosis of HOA were selected and randomly assigned to Kinesio tape plus exercise (KT-EXE) and exercise (EXE) groups. Each group included 19 subjects who participated in an 8-week intervention. Visual analog scale, Disabilities of the Arm, Shoulder, and Hand questionnaire, as well as goniometer and dynamometer measurements, were used to assess pain severity, upper extremity functional disabilities, ROM, and grip strength, respectively, before and after the intervention and at 2 months of follow-up.

RESULTS

There was no significant difference in pre-intervention scores between the two groups. Statistical analysis revealed significant improvement in pain, ROM, hand strength, and upper-extremity functional abilities after the intervention in KT-EXE and EXE groups. In addition, the follow-up analysis showed significant changes, compared to the initial assessments except for the pain in the EXE group. Results of the independent t-test revealed that change was significantly greater in KT-EXE group than that in the EXE group at post-intervention and 2-month follow-up assessments except for the wrist flexion and upper-extremity functional abilities at final evaluation.

CONCLUSION

Obtained results of this study showed that Kinesio taping and hand exercise may have a positive effect on the improvement of pain, ROM, hand strength, and upper-extremity functional abilities in patients with HOA. In addition, these two methods can be simultaneously used for the rehabilitation of this condition.

Effectiveness of splinting for pain and function in people with thumb carpometacarpal osteoarthritis: a systematic review with meta-analysis

OBJECTIVE

To examine the effectiveness of splinting for reducing pain and improving function and health-related quality of life (HR-QoL) in people with thumb carpometacarpal osteoarthritis (CMC OA).

DESIGN

The Cochrane Library, MEDLINE, Embase, CINAHL, ISI Web of Science, Scopus and Google Scholar, 3 trial registries and 4 conference proceedings were systematically searched for randomised and non-randomised controlled trials up to March 17th, 2018. Two reviewers independently applied the inclusion criteria to select potential studies and assess risk of methodologic bias using the Cochrane Collaboration's Risk of Bias Tool. Studies were pooled using the inverse variance method to calculate standardised mean difference (SMD). Sensitivity analyses were conducted and the quality of evidence for each outcome was judged following the Grades of Recommendation Assessment, Development and Evaluation (GRADE) approach.

RESULTS

Twelve studies were retrieved (n = 1353), 4 comparing a splint to control and 8 to another splint. In the medium-term (3-12 months), low quality evidence showed that splints cause a moderate to large reduction in pain (SMD 0.7 [95% confidence interval (CI) 1.04, 0.35], P < 0.0001) and small to moderate improvement in function (SMD 0.42 [95% CI 0.77, 0.08], P = 0.02). No significant effect was found at short-term or for different types of splints. No studies reported HR-QoL.

CONCLUSIONS

Splinting demonstrated a moderate to large effect for pain and small to moderate effect for function in the medium-term but not in the short term. Quality of the evidence is low. Major challenges are the lack of diagnostic criteria and of a gold-standard outcome measure for thumb CMC OA.

Quantitative proteomic analysis of dermal papilla from male androgenetic alopecia comparing before and after treatment with low-level laser therapy

BACKGROUND

Currently, low-level laser therapy (LLLT) has been approved as a new treatment for androgenetic alopecia (AGA). However, it has not been elucidated how LLLT promotes hair growth in vivo.

OBJECTIVES

To investigate the change in protein expression from dermal papilla (DP) tissues in male AGA patients after LLLT treatment using liquid chromatography tandem mass spectrometry (LC-MS/MS) analysis.

METHODS

This is an open-label, prospective, single-arm study obtained punch scalp biopsy specimens from patients with AGA before and after LLLT treatment. Each subject was self-treated with helmet type of LLLT (655 nm, 5 mW) device at home for 25 minutes per treatment every other day for 24 weeks. LC-MS/MS analysis based on the dimethyl labeling strategy for protein quantification was used to identify proteins expressed in DP tissues from AGA patients.

RESULTS

Proteomic analysis revealed 11 statistically significant up-regulated and 2 down-regulated proteins in LLLT treated DP compared with baseline (P < 0.05). A bioinformatic analysis signifies that these proteins are involved in several biological processes such as regulation of cellular transcription, protein biosynthesis, cell energy, lipid homeostasis, extracellular matrix (ECM), ECM structural constituent, cell-cell/cell-matrix adhesion as well as angiogenesis. ATP-binding cassette sub-family G member, a transporter involved in cellular lipid homeostasis, was the most up-regulated protein. Additionally, LLLT increased the main ECM proteins in DP which results in a bigger volume of DP and a clinical improvement of hair diameter in AGA patients.

CONCLUSION

We identified the proteome set of DP proteins of male patients with AGA treated with LLLT which implicates the role of LLLT in promoting hair growth and reversing of miniaturization process of AGA by enhancing DP cell function. Our results strongly support the benefit of LLLT in the treatment of AGA. Lasers Surg. Med. © 2019 Wiley Periodicals, Inc.

Orthosis for rhizarthrosis: A systematic review and meta-analysis

OBJECTIVE

investigating the effectiveness of orthosis for rhizarthrosis by means of a systematic review and meta-analysis.

METHODS

A systematic review was carried out using eight electronic databases. The randomized controlled trials included were those presenting subjects using orthosis for rhizarthrosis compared with individuals without orthosis or other rehabilitation interventions, as well as studies that compared different types of orthosis. The systematic review was performed according to the Cochrane methodology. The statistical software Review Manager 5.3 was employed to analyze the data.

RESULTS

Fourteen studies were included in the review and three of them participated in the meta-analysis. The orthosis group had a reduction in pain in the long term as compared to the control group with a statistically significant difference, a medium effect size, and low-quality evidence [Effect size -0.52, Confidence Interval 95% -0.94 to -0.11, p = 0.01), I²= 50%]. The orthosis group presented improvements regarding function in the long term as compared to control group, with a statistically significant difference, a medium effect size, and moderate quality of evidence [Effect size -0.44, Confidence Interval 95% -0.72 to -0.15, p = 0.002), I²= 0%].

CONCLUSION

the orthosis for rhizarthrosis presents low-quality evidence for reducing pain in the long term and moderate evidence for an increase in function in the long term. Since imprecision and inconsistency of the data were aspects which influenced the quality of the evidence, future studies with larger samples and standardized data are needed.

Is a joint-specific home exercise program effective for patients with first carpometacarpal joint osteoarthritis? A critical review

Introduction

First carpometacarpal joint osteoarthritis is a common degenerative condition. The thumb has been reported to account for up to 50% of hand function and is functionally and biomechanically unique in the hand. To this end, it would seem appropriate that exercise programs for first carpometacarpal joint osteoarthritis would be specifically tailored to the thumb. However, this is not widely reflected in the literature. This review aimed to critically evaluate studies presenting primary evidence to determine whether a joint-specific exercise program is effective for patients with osteoarthritis in the first carpometacarpal joint.

Methods

Six electronic databases were searched for papers presenting primary data relating to home exercise programs that were specific to osteoarthritis in the first carpometacarpal joint. Methodological quality of included papers was evaluated using the Structured Effectiveness for Evaluation of Studies tool and levels of evidence were established based on National Health and Medical Research Council (NHMRC) guidelines. Qualitative analysis of the combined body of literature was performed and a recommendation generated and then graded according to NHMRC guidelines.

Results

Searching identified three relevant papers. Overall, methodological quality was moderate, with limitations primarily related to lack of power. Findings from the body of literature demonstrated considerable variation, but evidence to support specific thumb strengthening exercises was found. This provided an NHMRC Grade D level of recommendation.

Conclusions

It is recommended that future studies consider optimal frequency of strengthening exercises and the potential role of adductor pollicis release and passive carpometacarpal joint mobilization in home exercise programs for first carpometacarpal osteoarthritis.

The Ottawa Panel guidelines on programmes involving therapeutic exercise for the management of hand osteoarthritis

OBJECTIVE:

To identify programmes involving therapeutic exercise that are effective for the management of hand osteoarthritis and to provide stakeholders with updated, moderate to high-quality recommendations supporting exercises for hand osteoarthritis.

METHODS:

A systematic search and adapted selection criteria included comparable trials with exercise programmes for managing hand osteoarthritis. Based on the evaluated evidence, a panel of experts reached consensus through a Delphi approach endorsing the recommendations. A hierarchical alphabetical grading system (A, B, C+, C, C-, D-, D, D+, E, F) was based on clinical importance (≥15%) and statistical significance ( P < 0.05).

RESULTS:

Ten moderate- to high-quality studies were included. Eight studies with programmes involving therapeutic exercise (e.g. range of motion (ROM) + isotonic + isometric + functional exercise) seemed to be effective. Forty-six positive grade recommendations (i.e. A, B, C+) were obtained during short-term (<12 weeks) trials for pain, stiffness, physical function, grip strength, pinch strength, range of motion, global assessment, pressure pain threshold, fatigue and abductor pollicis longus moment and during long-term (>12 weeks) trials for physical function and pinch strength.

CONCLUSION:

Despite that many programmes involving exercise with positive recommendations for clinical outcomes are available to healthcare professionals and hand osteoarthritis patients that aid in the management of hand osteoarthritis, there is a need for further research to isolate the specific effect of exercise components.

The knitting community-based trial for older women with osteoarthritis of the hands: design and rationale of a randomized controlled trial

BACKGROUND

The prevalence of hand osteoarthritis (HOA) has been reported to be higher amongst women over 50 years old (66%) compared to men of the same age (34%). Although exercise therapy has been shown effective in reducing symptoms and disability associated with HOA, adherence to treatment programs remains low. The primary objective of this RCT is to examine the effectiveness of a 12-week knitting program for morning stiffness (primary outcome) and pain relief (secondary outcome) 2 h post-wakening in females (aged 50 to 85 years old) with mild to moderate hand osteoarthritis (HOA).

METHODS/DESIGN

A single-blind, two-arm randomized controlled trial (RCT) with a parallel group design will be used to reach this objective and compare results to a control group receiving an educational pamphlet on osteoarththritis (OA) designed by the Arthritis Society. The premise behind the knitting program is to use a meaningful occupation as the main component of an exercise program. The knitting program will include two components: 1) bi-weekly 20-min knitting sessions at a senior's club and 2) 20-min home daily knitting sessions for the five remaining weekdays. Participants assigned to the control group will be encouraged to read the educational pamphlet and continue with usual routine. Pain, morning stiffness, hand function, self-efficacy and quality of life will be measured at baseline, six weeks, 12 weeks (end of program) with standardized tools. We hypothesize that participants in the knitting program will have significant improvements in all clinical outcomes compared to the control group. A published case study as well as the preliminary results of a feasibility study as examined through a 6-week pre-post study (n = 5 women with HOA) involving 20-min daily knitting morning sessions led to this proposed randomized controlled trial research protocol. This article describes the intervention, the empirical evidence to support it.

DISCUSSION

This knitting RCT has the potential to enhance our understanding of the daily HOA symptoms control and exercise adherence, refine functional exercise recommendations in this prevalent disease, and reduce the burden of disability in older women.

Guidelines for the conduct of pharmacological clinical trials in hand osteoarthritis: Consensus of a Working Group of the European Society on Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO)

OBJECTIVES

To gather expert opinion on the conduct of clinical trials that will facilitate regulatory review and approval of appropriate efficacious pharmacological treatments for hand osteoarthritis (OA), an area of high unmet clinical need.

METHODS

The European Society on Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal diseases (ESCEO) organized a working group under the auspices of the International Osteoporosis Foundation (IOF) and the World Health Organization (WHO).

RESULTS

This consensus guideline is intended to provide a reference tool for practice, and should allow for better standardization of the conduct of clinical trials in hand OA. Hand OA is a heterogeneous disease affecting different, and often multiple, joints of the thumb and fingers. It was recognized that the various phenotypes and limitations of diagnostic criteria may make the results of hand OA trials difficult to interpret. Nonetheless, practical recommendations for the conduct of clinical trials of both symptom and structure modifying drugs are outlined in this consensus statement, including guidance on study design, execution, and analysis.

CONCLUSIONS

While the working group acknowledges that the methodology for performing clinical trials in hand OA will evolve as knowledge of the disease increases, it is hoped that this guidance will support the development of new pharmacological treatments targeting hand OA.

The efficacy of peloid therapy in management of hand osteoarthritis: a pilot study

Hand osteoarthritis (OA) is associated with pain, reduced grip strength, loss of range of motion (ROM), and joint stiffness, leading to impaired hand function and difficulty in performance of daily living activities. Mud bath therapy has been reported to play a primary role in the prevention and management of OA. Thus, we planned to conduct a study aimed at investigating the effects of peloid therapy on pain, functional state, grip strength, and the quality of life and performing a comparative analysis of the outcomes of peloid therapy. In this randomized, controlled, single-blind, pilot study, patients (n = 33) underwent peloid therapy over 2 weeks, 5 sessions a week, for a total of 10 sessions and home exercise program in group 1. Patients in group 2 (control, n = 30) received only the same home exercise program as in group 1. Patients were evaluated just before, and 2 and 6 weeks after the start of the study with Visual Analogue Scale (VAS), Australian/Canadian Hand Osteoarthritis Index (AUSCAN), Health Assessment Questionnaire (HAQ), hand grip strength (HGS), and pinch strength (PS). Statistically significant improvements were observed in all parameters assessed at week 2 and week 6 in the group 1 (p < 0.05). Statistically significant differences were observed in HGS scores in the group 2 at week 2 and in AUSCAN scores at week 6 (p < 0.05). Intergroup comparisons of the scores revealed significant differences between the peloid therapy group and control group in VAS, HAQ, AUSCAN, HGS, and PS scores at week 2 and week 6 (p < 0.05). This study demonstrates that peloid therapy might be an effective and confident treatment modality in the management of symptomatic osteoarthritis of the hand and may provide effective pain control and improvements in the hand functions, quality of life, and grip strength.

Exercise for Hand Osteoarthritis: A Cochrane Systematic Review

OBJECTIVE

To assess the benefits and harms of exercise compared with other interventions, including placebo or no intervention, in people with hand osteoarthritis (OA).

METHODS

Systematic review using Cochrane Collaboration methodology. Six electronic databases were searched up until September 2015.

INCLUSION CRITERIA

randomized or controlled clinical trials comparing therapeutic exercise versus no exercise, or comparing different exercise programs.

MAIN OUTCOMES

hand pain, hand function, finger joint stiffness, quality of life, adverse events, and withdrawals because of adverse effects. Risk of bias and quality of the evidence were assessed.

RESULTS

Seven trials were included in the review, and up to 5 trials (n = 381) were included in the pooled analyses with data from postintervention. Compared to no exercise, low-quality evidence indicated that exercise may improve hand pain [5 trials, standardized mean difference (SMD) -0.27, 95% CI -0.47 to -0.07], hand function (4 trials, SMD -0.28, 95% CI -0.58 to 0.02), and finger joint stiffness (4 trials, SMD -0.36, 95% CI -0.58 to -0.15) in people with hand OA. Quality of life was evaluated by 1 study (113 participants) showing very low-quality evidence for no difference. Three studies reported on adverse events, which were very few and not severe.

CONCLUSION

Pooled results from 5 studies with low risk of bias showed low-quality evidence for small to moderate beneficial effects of exercise on hand pain, function, and finger joint stiffness postintervention. Estimated effect sizes were small, and whether they represent a clinically important change may be debated.

Attitudes, beliefs and common practices of hand therapists for base of thumb osteoarthritis in Australia (The ABC Thumb Study)

Introduction

The purpose of this study was to identify attitudes, beliefs and common practices of hand therapists in Australia regarding assessment and management of base of thumb osteoarthritis.

Methods

Monthly emails with a link to a 57-item cross-sectional survey were sent to members of the Australian Hand Therapy Association between November 2015 and February 2016. The survey included a case scenario of a patient with base of thumb osteoarthritis with questions about assessment and non-pharmacological and non-surgical treatment interventions for this case. Participants also rated their agreement with a series of 20 attitude and belief statements on a 6-point Likert scale. Data underwent descriptive analysis.

Results

A total of 124 therapists accessed the survey, of which 77 (62%) returned completed answers and 47 (38%) partially completed it. The majority were occupational therapists (n = 92, 74%), and the remaining were physiotherapists. The most common clinical assessment methods used for base of thumb osteoarthritis were palpation (96%), range of motion (90%), the grind test (85%), and pain on opposition across the palm (82%). The commonly reported treatments included a combination of orthosis prescription (92%), pain education (78%), heat (75%) and exercise (74%).

Conclusion

The findings highlight commonly used assessment tools and treatments for a typical patient with base of thumb osteoarthritis. Despite the low response rate, there is consistency among general treatment for base of thumb osteoarthritis. Variation exists within the specifics of exercise and orthosis prescription. The results of the survey reflect the lack of standardised recommendations for the management of base of thumb osteoarthritis.

The effects of resistance training on muscle strength, joint pain, and hand function in individuals with hand osteoarthritis: a systematic review and meta-analysis

Background

Hand osteoarthritis is a common condition characterised by joint pain and muscle weakness. These factors are thought to contribute to ongoing disability. Some evidence exists that resistance training decreases pain, improves muscle strength, and enhances function in people with knee and hip osteoarthritis. However, there is currently a lack of consensus regarding its effectiveness in people with hand osteoarthritis. Therefore, the aim of this systematic review and meta-analysis was to establish whether resistance training in people with hand osteoarthritis increases grip strength, decreases joint pain, and improves hand function.

Methods

Seven databases were searched from 1975 until July 1, 2016. Randomised controlled trials were included. The Cochrane Risk of Bias Tool was used to assess studies’ methodological quality. The Grade of Recommendations Assessment, Development, and Evaluation system was adopted to rate overall quality of evidence. Suitable studies were pooled using a random-effects meta-analysis.

Results

Five studies were included with a total of 350 participants. The majority of the training programs did not meet recommended intensity, frequency, or progression criteria for muscle strengthening. There was moderate-quality evidence that resistance training does not improve grip strength (mean difference = 1.35; 95% confidence interval (CI) = –0.84, 3.54; I² = 50%; p = 0.23 ). Low-quality evidence showed significant improvements in joint pain (standardised mean difference (SMD) = –0.23; 95% CI = –0.42, –0.04; I² = 0%; p = 0.02) which were not clinically relevant. Low-quality evidence demonstrated no improvements in hand function following resistance training (SMD = –0.1; 95% CI = –0.33, 0.13; I² = 28%; p = 0.39).

Conclusion

There is no evidence that resistance training has a significant effect on grip strength or hand function in people with hand osteoarthritis. Low-quality evidence suggests it has a small, clinically unimportant pain-relieving effect. Future studies should investigate resistance training regimes with adequate intensity, frequency, and progressions to achieve gains in muscle strength.

PANLAR Consensus Recommendations for the Management in Osteoarthritis of Hand, Hip, and Knee

OBJECTIVE

The objective of this consensus is to update the recommendations for the treatment of hand, hip, and knee osteoarthritis (OA) by agreeing on key propositions relating to the management of hand, hip, and knee OA, by identifying and critically appraising research evidence for the effectiveness of the treatments and by generating recommendations based on a combination of the available evidence and expert opinion of 18 countries of America.

METHODS

Recommendations were developed by a group of 48 specialists of rheumatologists, members of other medical disciplines (orthopedics and physiatrists), and three patients, one for each location of OA. A systematic review of existing articles, meta-analyses, and guidelines for the management of hand, hip, and knee OA published between 2008 and January 2014 was undertaken. The scores for Level of Evidence and Grade of Recommendation were proposed and fully consented within the committee based on The American Heart Association Evidence-Based Scoring System. The level of agreement was established through a variation of Delphi technique.

RESULTS

Both "strong" and "conditional" recommendations are given for management of hand, hip, and knee OA and nonpharmacological, pharmacological, and surgical modalities of treatment are presented according to the different levels of agreement.

CONCLUSIONS

These recommendations are based on the consensus of clinical experts from a wide range of disciplines taking available evidence into account while balancing the benefits and risks of nonpharmacological, pharmacological, and surgical treatment modalities, and incorporating their preferences and values. Different backgrounds in terms of patient education or drug availability in different countries were not evaluated but will be important.

Effects of client-centered multimodal treatment on impairment, function, and satisfaction of people with thumb carpometacarpal osteoarthritis

STUDY DESIGN

Prepost design.

INTRODUCTION

Previous research regarding the non-surgical treatment of thumb carpometacarpal joint osteoarthritis has been based on protocol driven research designs that primarily examined impairment level changes. Exploration is therefore needed to determine the benefits of individually prescribed orthoses, joint protection and assistive device education programs that are based on the activities the person needs to regularly perform.

PURPOSE OF THE STUDY

The primary objective of this study was to examine the effect of client-centered multimodal treatment on activity, participation, impairment, and satisfaction of people with thumb carpometacarpal joint osteoarthritis.

METHODS

A total of 60 participants completed the study that used a prepost design. The Canadian Occupational Performance Measure (COPM) was used to identify the participants' performance and satisfaction concerning their self-identified occupational performance issues. Additional outcome measures that were used included the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, total active range of motion (TAROM), lateral pinch strength, and the visual analog scale for pain. All participants completed a client-centered 6-week program that consisted of the use of an orthosis, joint protection, and assistive device education as well as exercises.

RESULTS

At 6 weeks after initiation of treatment, pain, pinch strength, TAROM, the DASH questionnaire and the performance and satisfaction scales of the COPM had significantly improved. The changes in pain, TAROM, and the performance and satisfaction scales of the COPM were all greater than the minimal clinically important difference. The changes in pain and lateral pinch strength were significantly associated with changes in activity and participation.

DISCUSSION

This study demonstrated that a multimodal, client-centered treatment approach resulted in statistically and clinically significant improvement in pain, TAROM and performance and satisfaction as measured by the COPM. The improvement in pain was associated with the participants' improved ability to engage in activities assessed by the DASH.

CONCLUSIONS

Our results support the use of client-centered treatment strategies that are targeted to control pain during meaningful activity when working with patients with thumb carpometacarpal joint osteoarthritis therapists.

Exercise for hand osteoarthritis

BACKGROUND

Hand osteoarthritis (OA) is a prevalent joint disease that may lead to pain, stiffness and problems in performing hand-related activities of daily living. Currently, no cure for OA is known, and non-pharmacological modalities are recommended as first-line care. A positive effect of exercise in hip and knee OA has been documented, but the effect of exercise on hand OA remains uncertain.

OBJECTIVES

To assess the benefits and harms of exercise compared with other interventions, including placebo or no intervention, in people with hand OA. Main outcomes are hand pain and hand function.

SEARCH METHODS

We searched six electronic databases up until September 2015.

SELECTION CRITERIA

All randomised and controlled clinical trials comparing therapeutic exercise versus no exercise or comparing different exercise programmes.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected trials, extracted data, assessed risk of bias and assessed the quality of the body of evidence using the GRADE approach. Outcomes consisted of both continuous (hand pain, physical function, finger joint stiffness and quality of life) and dichotomous outcomes (proportions of adverse events and withdrawals).

MAIN RESULTS

We included seven studies in the review. Most studies were free from selection and reporting bias, but one study was available only as a congress abstract. It was not possible to blind participants to treatment allocation, and although most studies reported blinded outcome assessors, some outcomes (pain, function, stiffness and quality of life) were self-reported. The results may be vulnerable to performance and detection bias owing to unblinded participants and self-reported outcomes. Two studies with high drop-out rates may be vulnerable to attrition bias. We downgraded the overall quality of the body of evidence to low owing to potential detection bias (lack of blinding of participants on self-reported outcomes) and imprecision (studies were few, the number of participants was limited and confidence intervals were wide for the outcomes pain, function and joint stiffness). For quality of life, adverse events and withdrawals due to adverse events, we further downgraded the overall quality of the body of evidence to very low because studies were very few and confidence intervals were very wide.Low-quality evidence from five trials (381 participants) indicated that exercise reduced hand pain (standardised mean difference (SMD) -0.27, 95% confidence interval (CI) -0.47 to -0.07) post intervention. The absolute reduction in pain for the exercise group, compared with the control group, was 5% (1% to 9%) on a 0 to 10 point scale. Pain was estimated to be 3.9 points on this scale (0 = no pain) in the control group, and exercise reduced pain by 0.5 points (95% CI 0.1 to 0.9; number needed to treat for an additional beneficial outcome (NNTB) 9).Four studies (369 participants) indicated that exercise improved hand function (SMD -0.28, 95% CI -0.58 to 0.02) post intervention. The absolute improvement in function noted in the exercise group, compared with the control group, was 6% (0.4% worsening to 13% improvement). Function was estimated at 14.5 points on a 0 to 36 point scale (0 = no physical disability) in the control group, and exercise improved function by 2.2 points (95% CI -0.2 to 4.6; NNTB 9).One study (113 participants) evaluated quality of life, and the effect of exercise on quality of life is currently uncertain (mean difference (MD) 0.30, 95% CI -3.72 to 4.32). The absolute improvement in quality of life for the exercise group, compared with the control group, was 0.3% (4% worsening to 4% improvement). Quality of life was 50.4 points on a 0 to 100 point scale (100 = maximum quality of life) in the control group, and the mean score in the exercise group was 0.3 points higher (3.5 points lower to 4.1 points higher).Four studies (369 participants) indicated that exercise reduced finger joint stiffness (SMD -0.36, 95% CI -0.58 to -0.15) post intervention. The absolute reduction in finger joint stiffness for the exercise group, compared with the control group, was 7% (3% to 10%). Finger joint stiffness was estimated at 4.5 points on a 0 to 10 point scale (0 = no stiffness) in the control group, and exercise improved stiffness by 0.7 points (95% CI 0.3 to 1.0; NNTB 7).Three studies reported intervention-related adverse events and withdrawals due to adverse events. The few reported adverse events consisted of increased finger joint inflammation and hand pain. Low-quality evidence from the three studies showed an increased likelihood of adverse events (risk ratio (RR) 4.55, 95% CI 0.53 to 39.31) and of withdrawals due to adverse events in the exercise group compared with the control group (RR 2.88, 95% CI 0.30 to 27.18), but the effect is uncertain and further research may change the estimates.Included studies did not measure radiographic joint structure changes. Two studies provided six-month follow-up data (220 participants), and one (102 participants) provided 12-month follow-up data. The positive effect of exercise on pain, function and joint stiffness was not sustained at medium- and long-term follow-up.The exercise intervention varied largely in terms of dosage, content and number of supervised sessions. Participants were instructed to exercise two to three times a week in four studies, daily in two studies and three to four times daily in another study. Exercise interventions in all seven studies aimed to improve muscle strength and joint stability or function, but the numbers and types of exercises varied largely across studies. Four studies reported adherence to the exercise programme; in three studies, this was self-reported. Self-reported adherence to the recommended frequency of exercise sessions ranged between 78% and 94%. In the fourth study, 67% fulfilled at least 16 of the 18 scheduled exercise sessions.

AUTHORS' CONCLUSIONS

When we pooled results from five studies, we found low-quality evidence showing small beneficial effects of exercise on hand pain, function and finger joint stiffness. Estimated effect sizes were small, and whether they represent a clinically important change may be debated. One study reported quality of life, and the effect is uncertain. Three studies reported on adverse events, which were very few and were not severe.

Efficacy of combined conservative therapies on clinical outcomes in patients with thumb base osteoarthritis: protocol for a randomised, controlled trial (COMBO)

INTRODUCTION

Management of thumb base osteoarthritis (OA) using a combination of therapies is common in clinical practice; however, evidence for the efficacy of this approach is lacking. The aim of this study is to determine the effect of a combination of conservative therapies for the treatment of thumb base OA compared with an education control group.

METHODS AND ANALYSIS

This is a randomised, controlled, single-centre, two-arm superiority trial with 1:1 allocation ratio; with assessor and statistician blinded. Participants are blinded to the trial's hypothesis and to the interventions received by the opposite group. A total of 204 participants will be recruited from the community and randomised using a computer-generated schedule. The intervention group will receive education for joint protection and OA, a splint for the base of the thumb, hand exercises and topical diclofenac sodium 1% gel over 6 weeks. The control group will receive education for joint protection and OA alone. Main inclusion criteria are pain ≥40 mm (Visual Analogue Scale, 0-100) at the base of the thumb, impairment in hand function ≥6 (Functional Index for Hand Osteoarthritis, 0-30) and radiographic thumb base OA (Kellgren Lawrence grade ≥2). Participants currently receiving any of the intervention components will be excluded. Outcomes will be measured at 2, 6 and 12 weeks. The primary outcome is change in pain and hand function from baseline to 6 weeks. Other outcomes include changes in grip and pinch strength, quality of life, presence of joint swelling and tenderness, duration of joint stiffness, patient's global assessment and use of rescue medication. Analysis will be performed according to the intention-to-treat principle. Adverse events will be monitored throughout the study.

ETHICS AND DISSEMINATION

This protocol is approved by the local ethics committee (HREC/15/HAWKE/479). Dissemination will occur through presentations at international conferences and publication in peer-reviewed journals.

Evaluation of Hand Forces During a Joint-Protection Strategy for Women With Hand Osteoarthritis

OBJECTIVE

We evaluated whether a joint-protection strategy changes the mechanics of opening a sealed jar.

METHOD

Thirty-one adult women with hand osteoarthritis attempted to open a "sealed" jar instrument when using and not using nonskid material. Grip force, torque, success, and pain were recorded for each trial.

RESULTS

Participants used less grip force when twisting with their left hand. The greatest torque and success, yet the least amount of grip force across time, and pain was noted when the left hand turned the lid, the jar was held vertically, the right hand supported the base, and nonskid material was used.

CONCLUSION

Women with hand osteoarthritis should be educated to consider the hand they use and their approach when opening sealed jars. Use of nonskid material without additional reasoning may increase load on arthritic joints, pain, and dysfunction. Additional research on task kinematics and the kinetics of the stabilizing hand is needed.

Does occupational therapy reduce the need for surgery in carpometacarpal osteoarthritis? Protocol for a randomized controlled trial

BACKGROUND

In the absence of disease-modifying interventions for hand osteoarthritis (OA), occupational therapy (OT) comprising patient education, hand exercises, assistive devices and orthoses are considered as core treatments, whereas surgery are recommended for those with severe carpometacarpal (CMC1) OA. However, even though CMC1 surgery may reduce pain and improve function, the risk of adverse effects is high, and randomized controlled trials comparing surgery with non-surgical interventions are warranted. This multicentre randomized controlled trial aims to address the following questions: Does OT in the period before surgical consultation reduce the need for surgery in CMC1-OA? What are patients' motivation and reasons for wanting CMC1-surgery? Are there differences between departments of rheumatology concerning the degree of CMC1-OA, pain and functional limitations in patients who are referred for surgical consultation for CMC1 surgery? Is the Measure of Activity Performance of the Hand a reliable measure in patients with CMC1-OA? Do patients with CMC1-OA with and without affection of the distal and proximal interphalangeal finger joints differ with regard to symptoms and function? Do the degree of CMC1-OA, symptoms and functional limitations significantly predict improvement after 2 years following OT or CMC1-surgery? Is OT more cost-effective than surgery in the management of CMC1-OA?

METHODS/DESIGN

All persons referred for surgical consultation due to their CMC1-OA at one of three Norwegian departments of rheumatology are invited to participate. Those who agree attend a clinical assessment and report their symptoms, function and motivation for surgery in validated outcome measures, before they are randomly selected to receive OT in the period before surgical consultation (estimated n = 180). The primary outcome will be the number of participants in each group who have received surgical treatment after 2 years. Secondary and tertiary outcomes are pain, function and satisfaction with care over the 2-year trial period. Outcomes will be collected at baseline, 4, 18 and 24 months. The main analysis will be on an intention-to-treat basis, using logistic regression, comparing the number of participants in each group who have received surgical treatment after 2 years.

DISCUSSION

The findings will improve the evidence-based management of HOA.

First dorsal interosseous muscle contraction results in radiographic reduction of healthy thumb carpometacarpal joint

INTRODUCTION

Hand therapists selectively strengthen the first dorsal interosseus (FDI) to stabilize arthritic joints yet the role of the FDI has not yet been radiographically validated.

PURPOSE

To determine if FDI contraction reduces radial subluxation (RS) of the thumb metacarpal (MC).

METHODS

Fluoroscopy was used to obtain true anterior-posterior radiographs of non-arthritic CMC joints: 1) at rest, 2) while stressed and 3) while stressed with maximal FDI contraction. Maximal FDI strength during CMC stress and thumb MC RS and trapezial articular width were measured. The ratio of RS to the articular width was calculated.

RESULTS

Seventeen participants (5 male, 12 female) participated. Subluxation of a stressed CMC significantly reduced and the subluxation to articular width ratio significantly improved after FDI activation.

CONCLUSIONS

Contraction of the FDI appears to radiographically reduce subluxation of the healthy thumb CMC joint. Further exploration on the FDI's reducibility and its carry-over effects in arthritic thumbs is needed.

Effects of rehabilitation for pain relief in patients with rheumatoid arthritis: a systematic review

[Purpose] The purpose of this study was to find evidence for the effectiveness of rehabilitation for pain relief in patients with rheumatoid arthritis. [Subjects and Methods] A systematic review was conducted of MEDLINE, The Cochrane Central Register of Controlled Trials (CENTRAL), and OVID, for studies published from July 2005 to July 2015. We extracted data regarding patients, intervention, comparison, and outcomes, and assessed the methodological quality of the data. [Results] Nine randomized controlled trials comparing the effects of pain relief in patients with rheumatoid arthritis were found. [Conclusion] Physical therapy and occupational therapy can reduce pain in rheumatoid arthritis.

Effectiveness of physical and occupational therapy on pain, function and quality of life in patients with trapeziometacarpal osteoarthritis - A systematic review and meta-analysis

Introduction

Trapeziometacarpal osteoarthritis is associated with more pain and restrictions than other hand osteoarthritis due to the functional importance of the thumb. While the effectiveness of surgical and pharmacological interventions has been widely examined, there is a lack of specific evidence about conservative non-pharmacological trapeziometacarpal osteoarthritis therapies. The objective of this systematic review was to provide evidence-based knowledge on the effectiveness of physiotherapy and occupational therapy on pain, function and quality of life.

Methods

A literature search of Medline, CINAHL, PEDro, OTseeker, EMB Dare Cochrane Database of Systematic Reviews and Cochrane CENTRAL was performed. Randomized and quasi-randomized controlled trials and corresponding systematic reviews, observational studies, pragmatic studies and case–control studies were included. The risk of bias was assessed.

Results

Out of 218 studies, 27 were retained. A narrative summary and a series of meta-analyses were performed. Concerning pain reduction, the meta-analysis showed parity of pre-fabricated neoprene and custom-made thermoplastic splints: standardized mean difference (SMD) –0.01 (95%CI −0.43, 0.40) (p=0.95). Multimodal interventions are more effective on pain compared to single interventions: standardized mean difference −3.16 (95%CI −5.56, −0.75) (p = 0.01).

Discussion

Physical and occupational therapy-related interventions, especially multimodal interventions, seem to be effective to treat pain in patients with trapeziometacarpal osteoarthritis. Pre-fabricated neoprene splints and custom-made thermoplastic splints may reduce pain equally. Single interventions seem not to be effective. Significant evidence for effectiveness on function and quality of life could not be found.

Does Using a Chair Backrest or Reducing Seated Hip Flexion Influence Trunk Muscle Activity and Discomfort? A Systematic Review

OBJECTIVE

This paper systematically reviews the effect of chair backrests and reducing seated hip flexion on low back discomfort (LBD) and trunk muscle activation.

BACKGROUND

Prolonged sitting commonly exacerbates low back pain (LBP). Several modifications to seated posture and chair design have been recommended, including using chairs with backrests and chairs that reduce hip flexion.

METHOD

Electronic databases were searched by two independent assessors. Part 1 of this review includes 26 studies comparing the effect of sitting with at least two different hip angles. In Part 2, seven studies that compared the effect of sitting with and without a backrest were eligible. Study quality was assessed using the PEDro scale.

RESULTS

Significant confounding variables and a relatively small number of randomized controlled trials (RCTs) involving people with LBP complicates analysis of the results. There was moderate evidence that chair backrests reduce paraspinal muscle activation, and limited evidence that chair backrests reduce LBD. There was no evidence that chairs involving less hip flexion reduce LBP or LBD, or consistently alter trunk muscle activation. However, participants in several studies subjectively preferred the modified chairs involving less hip flexion.

CONCLUSION

The limited evidence to support the use of chairs involving less seated hip flexion, or the effect of a backrest, is consistent with the limited evidence that other isolated chair design features can reduce LBP.

APPLICATION

LBP management is likely to require consideration of several factors in addition to sitting position. Larger RCTs involving people with LBP are required.

[Salutogenic concepts in the rehabilitation of osteoarthritis]

BACKGROUND

The treatment strategies for osteoarthritis (OA) are well known from numerous studies. One of the challenges is long-term patient compliance to the recommended therapies without supervision.

OBJECTIVE

To examine the ability of salutogenic concepts to improve rehabilitative management of OA.

MATERIALS AND METHODS

Review article introducing salutogenic concepts and their empiric evidence, focussing on Antonovsky's sense of coherence (SOC).

RESULTS

The SOC consists of the three components comprehensibility, manageability and meaningfulness. SOC can be quantified by SOC-13, a self-reported measurement with 13 items. Associations of the SOC with different dimensions of health (in particular with Short Form 36, SF-36) are known from cross-sectional studies. Most studies showed a stronger correlation of the mental than the physical health dimensions of SF-36 with SOC-13. This result is consistent with baseline examinations of hip and knee OA patients before rehabilitation. At the 6-month follow-up, correlations between SOC and the changes of the SF-36 scores were weak. A salutogenically orientated instruction for self-management of symptoms in cancer patients showed significant improvement in SOC.

CONCLUSION

Increasing SOC can lead to health improvements on many levels, e.g. self-efficacy, reduction of fear, coping, education, resources and compliance to treatment. Empirical proof that interventional measures increasing SOC can improve the health of OA patients is currently unavailable.

OARSI Clinical Trials Recommendations: Design and conduct of clinical trials for hand osteoarthritis

Hand osteoarthritis (OA) is a very frequent disease, but yet understudied. However, a lot of works have been published in the past 10 years, and much has been done to better understand its clinical course and structural progression. Despite this new knowledge, few therapeutic trials have been conducted in hand OA. The last OARSI recommendations for the conduct of clinical trials in hand OA dates back to 2006. The present recommendations aimed at updating previous recommendations, by incorporating new data. The purpose of this expert opinion, consensus driven exercise is to provide evidence-based guidance on the design, execution and analysis of clinical trials in hand OA, where published evidence is available, supplemented by expert opinion, where evidence is lacking, to perform clinical trials in hand OA, both for symptom and for structure-modification. They indicate core outcome measurement sets for studies in hand OA, and list the methods and instruments that should be used to measure symptoms or structure. For both symptom- and structure-modification, at least pain, physical function, patient global assessment, HR-QoL, joint activity and hand strength should be assessed. In addition, for structure-modification trials, structural progression should be measured by radiographic changes. We also provide a research agenda listing many unsolved issues that seem to most urgently need to be addressed from the perspective of performing "good" clinical trials in hand OA. These updated OARSI recommendations should allow for better standardizing the conduct of clinical trials in hand OA in the next future.

The effects of compression gloves on hand symptoms and hand function in rheumatoid arthritis and hand osteoarthritis: a systematic review

Objective:

to evaluate the effects of compression gloves in adults with rheumatoid arthritis and hand osteoarthritis.

Data sources:

Systematic review of randomized controlled trials identified from MEDLINE, CINAHL, AMED, PEDro, OT Seeker, The Cochrane Library, ISI Web of Knowledge, Science Direct and PubMed from their inceptions to January 2015.

Review methods:

Methodological quality of identified trials was evaluated using the PEDro scale by three independent assessors. Effects were summarized descriptively.

Results:

Four trials ( n=8-24; total n=74), comparing night wear of full-length finger compression gloves with placebo gloves, were assessed. Three were of moderate (PEDro score 4-5) and one low (score 3) methodological quality. Effect sizes or standardized mean differences could not be calculated to compare trials due to poor data reporting. In rheumatoid arthritis, finger joint swelling was significantly reduced, but results for pain and stiffness were inconclusive and no differences in grip strength and dexterity were identified. One study reported similar effects in pain, stiffness and finger joint swelling from both compression and thermal placebo gloves. Only one study evaluated gloves in hand osteoarthritis ( n=5) with no differences.

Conclusions:

All the trials identified were small with a high risk of Type I and II errors. Evidence for the effectiveness of compression gloves worn at night is inconclusive in rheumatoid arthritis and hand osteoarthritis.

Therapy gloves for patients with rheumatoid arthritis: a review

Rheumatoid arthritis is a chronic inflammatory disease that causes pain, joint stiffness and swelling leading to impaired hand function and difficulty with daily activities. Wearing therapy gloves has been recommended by occupational therapists as one of the alternative treatment methods for rheumatoid arthritis. This study aims to review the available literature on the effects of wearing therapy gloves on patients' hand function and symptoms as well as to discuss the attributes of gloves that might influence the glove performance. An electronic databases search of MEDLINE, Physiotherapy Evidence Database, Occupational Therapy Systematic Evaluation of Evidence, Wiley Online Library, ScienceDirect and Cochrane Central Register of Controlled Trial was performed. Eight articles met the inclusion criteria, and covered seven clinical trials and one case study. Seven outcome measures were identified from the included studies and were then classified into two categories: hand function and hand symptoms. The hand symptoms such as pain, stiffness and swelling improve substantially when the therapy gloves are used. However, marginal or no improvement in hand function (with the exception of grip strength) linked to the use of therapy gloves is being reported. Further research is needed to quantify the effectiveness of therapy gloves, especially in improvement of hand function and in patients' interest in wearing therapy gloves. Furthermore, future studies should include parameters which might influence therapy gloves' performance, such as duration of trials, interface pressure generated by the gloves on the underlying skin and tissue, glove fit and construction, as well as thermophysiological comfort.

Current practice patterns in conservative thumb CMC joint care: survey results

STUDY DESIGN

Cross-sectional descriptive survey

INTRODUCTION

Best practice for conservative clinical care pathways is not well outlined in the literature for patients with thumb carpometacarpal joint (CMCJ) pain. This self-report survey investigated the current practice patterns of assessments and conservative interventions for the painful thumb CMCJ among hand therapists.

METHODS

An online survey was distributed to members of the American Society of Hand Therapists (ASHT). Questions were included about evaluation measures and intervention techniques used for this population. A descriptive analysis was completed of the results.

RESULTS

A total of 23.5% of the ASHT membership responded to the survey. Results were categorized using the International Classification of Functioning and Disability domains as a framework. The survey results report varying use of evaluation measures, therapeutic interventions, including orthotic fabrication, joint protection and patient education all therapeutic interventional techniques, and modalities.

CONCLUSION

Therapists use a comprehensive array of evaluation measures and interventions for body functions and structures in the care of thumb CMC pain. In contrast, more consistent use is needed of psychometrically-sound functional outcome measures that show change in activities and participation. This survey highlights areas to employ current evidence, as well as, future research should address environmental factors and personal factors for this population

Exercise in osteoarthritis: moving from prescription to adherence

Exercise is recommended for the management of osteoarthritis (OA) in all clinical guidelines irrespective of disease severity, pain levels, and functional status. For knee OA, evidence supports the benefits of various types of exercise for improving pain and function in the short term. However, there is much less research investigating the effects of exercise in patients with OA at other joints such as the hip and hand. It is important to note that while the magnitude of exercise benefits may be considered small to moderate, these effects are comparable to reported estimates for simple analgesics and oral nonsteroidal anti-inflammatory drugs for OA pain but exercise has much fewer side effects. Exercise prescription should be individualized based on assessment findings and be patient centered involving shared decision making between the patient and clinician. Given that patient adherence to exercise declines over time, appropriate attention should be pain as reduced adherence attenuates the benefits of exercise. Given this, barriers and facilitators to exercise should be identified and strategies to maximize long-term adherence to exercise implemented.
