A systematic review of conservative interventions for osteoarthritis of the hand

Daytime Functional Usage Versus Night-Time Wearing: Identifying the Optimal Wearing Regimen for a Custom-Made Orthosis in the Treatment of Trapeziometacarpal Osteoarthritis

OBJECTIVE

To compare the functional (daytime) use to the nightly use of an orthosis for patients affected by trapeziometacarpal osteoarthritis (OA).

DESIGN

Randomized, controlled single-blind trial.

SETTING

The rheumatology outpatient clinic of the University.

PARTICIPANTS

Sixty participants diagnosed with trapeziometacarpal OA.

INTERVENTIONS

Participants were randomly assigned into 2 groups: a functional group that used a functional hand-based thumb immobilization orthosis during activities of daily living and a night-time group that used the same orthosis at night.

MAIN OUTCOMES MEASURES

The patients were evaluated at baseline and after 45, 90, 180, and 360 days considering: pain at the base of the thumb and in the hand, range of motion of the thumb, grip, and pinch strength, manual dexterity, and hand function.

RESULTS

The groups were homogeneous at the beginning of the trial. No statistically significant difference was observed between groups over time for trapeziometacarpal pain (P=.646). For general hand pain, no statistically significant difference was found between groups over time (P=.594). Although both groups improved from baseline, there were no statistically significant differences between the groups in the vast majority of the assessed parameters. Statistically significant differences between the groups were found only in the following outcomes: thumb palmar abduction of the right hand (P=.023), pick-up test with closed eyes of the right hand (P=.048), and tripod grip strength of the right hand (P=.006).

CONCLUSIONS

Both groups showed improvement in pain and function from baseline to the end of the intervention. However, there were no reported differences in these outcomes after a 1-year follow-up between the functional (daytime) and night-time use of orthosis in patients with trapeziometacarpal OA. This suggests that both types of usage can be offered to patients.

Surface Embedded Metal Nanowire-Liquid Metal-Elastomer Hybrid Composites for Stretchable Electronics

Both liquid metal (LM) and metallic filler-based conductive composites are promising stretchable conductors. LM alloys exhibit intrinsically high deformability but present challenges for patterning on polymeric substrates due to high surface tension. On the other hand, conductive composites comprising metallic fillers undergo considerable decrease in electrical conductivity under mechanical deformation. To address the challenges, we present silver nanowire (AgNW)-LM-elastomer hybrid composite films, where AgNWs and LM are embedded below the surface of an elastomeric matrix, using two fabrication approaches, sequential and mixed. We investigate and understand the process-structure-property relationship of the AgNW-LM-elastomer hybrid composites fabricated using two approaches. Different weight ratios of AgNWs and LM particles provide tunable electrical conductivity. The hybrid composites show more stable electromechanical performance than the composites with AgNWs alone. In particular, 1:2.4 (AgNW:LMP w/w) sequential hybrid composite shows electromechanical stability similar to that of the LM-elastomer composite, with a resistance increase of 2.04% at 90% strain. The sequential approach is found to form AgIn2 intermetallic compounds which along with Ga-In bonds, imparts large deformability to the sequential hybrid composite as well as mechanical robustness against scratching, cutting, peeling, and wiping. To demonstrate the application of the hybrid composite for stretchable electronics, a laser patterned stretchable heater on textile and a stretchable circuit including a light-emitting diode are fabricated.

Proximal Interphalangeal Joint Arthroplasty Using a Silicone Implant: A Comparison Between Integra and NeuFlex in 72 Cases

BACKGROUND

Osteoarthritis of the hand can lead to pain, stiffness, and deformation, and thus to functional disability. The purpose of this study was to compare short-term clinical outcomes of 2 silicone proximal interphalangeal (PIP) joint implants, NeuFlex and Integra, in patients with primary osteoarthritis.

METHODS

We included 72 PIP joints, of which 40 were replaced by a NeuFlex implant and 32 by an Integra implant. The average follow-up was 12 months for the Integra group and 16 months for the NeuFlex group.

RESULTS

There was no change in active flexion preoperatively and postoperatively. Extension lag and Disabilities of the Arm, Shoulder, and Hand score decreased substantially in both groups, whereas grip strength and Patient-Specific Functional Scale (PSFS) score increased. All patients were satisfied. Between groups, there was a significant difference in the PSFS score, in favor of the Integra group.

CONCLUSIONS

Both implants have excellent results, but more research is needed with more patients to prevent bias and to determine the long-term outcome of these implants.

Efficacy and Safety of High Density LED Irradiation Therapy for Patients With Hand Osteoarthritis: A Single-Center Clinical Study

OBJECTIVE

To assess the safety and effectiveness of high-density light-emitting diode (LED) irradiation therapy in patients with hand osteoarthritis (OA) and compare the pre- and post-intervention symptoms.

METHODS

Twenty-three patients with hand OA underwent eight sessions of high-density LED irradiation therapy directed at the five most painful areas in the finger joints. Each session lasted for 18 minutes; and the sessions were conducted twice a week, for 4 weeks. We evaluated the degree of pain using the visual analogue scale, ring size, and passive range of motion (flexion+extension) for two most painful joints from the baseline to post-therapy (weeks 4 and 6).

RESULTS

High-density LED irradiation therapy significantly reduced the pain posttreatment compared with that observed at the baseline (p<0.001). Although improvements were observed in ring size and joint range of motion at 4 and 6 weeks, they were not statistically significant (p>0.05). No adverse events were observed.

CONCLUSION

We examined the safety and effectiveness of high-density LED irradiation therapy in reducing pain and hand swelling and improving joint mobility in patients with hand OA. These results suggest that high-density LED irradiation therapy has the potential to be an important strategy for managing hand OA.

Effectiveness of proprioception training in functional recovery of thumb osteoarthritis. Single, multicenter, non-blind randomized clinical trial

BACKGROUND AND OBJECTIVES

Osteoarthritis at the base of the thumb (CMC-1 OA) is a pathology that mainly affects postmenopausal women. The main symptoms including pain, decreased hand-thumb strength and fine motor capacity. Although a proprioceptive deficit has already been demonstrated in people with CMC-1 OA, there is insufficient evidence regarding the effects of proprioceptive training. The main objective of this study is to determine the effectiveness of proprioceptive training in functional recovery.

MATERIALS AND METHODS

A total of 57 patients were included in the study, 29 in the control group and 28 in the experimental group. Both groups underwent the same basic intervention programme, but the experimental group included a proprioceptive training protocol. Variables of the study were pain (VAS), perception of occupational performance (COMP), sense position (SP) and force sensation (FS).

RESULTS

Statistically significant improvement was observed in the experimental group in pain (p < .05) and occupational performance (p < .001) after 3 months of treatment. No statistical differences were found in sense position (SP) or sensation of force (FS).

DISCUSSION AND CONCLUSIONS

The results concord with previous studies focussing on proprioception training. The incorporation of a proprioceptive exercise protocol reduces pain and significantly improves occupational performance.

Assessment and treatment of nonsurgical thumb carpometacarpal joint osteoarthritis: A modified Delphi-based consensus paper of the American Society of Hand Therapists

BACKGROUND

While the literature is abundant on hand therapy assessment and treatment of nonsurgical thumb carpometacarpal (CMC) osteoarthritis (OA), clarity and uniformity are meager, making it a desirable diagnosis to establish expert consensus.

PURPOSE

This study aimed to ascertain if consensus exists for the assessment and treatment of nonsurgical management of thumb CMC OA in the hand therapy clinical setting.

STUDY DESIGN

This was a consensus paper via the modified Delphi approach.

METHODS

A modified Delphi method was used to determine consensus among an expert panel, including hand therapists and hand surgeons, via two online surveys. A consensus paper steering committee (from the American Society of Hand Therapist's research division) designed the surveys and analyzed responses. Consensus was established as 75% agreement among the expert panel. Demographic information was collected from the expert panel.

RESULTS

The expert panel included 34 hand therapists and seven hand surgeons. The survey response rates were 93.6% for the first survey and 90.2% for the second survey. Consensus recommendations were classified according to the World Health Organization categorization. These included evaluating the body structures for clinical signs/clinical testing and body functions for pain, range of motion for palmar abduction, radial abduction, opposition, and thumb metacarpal phalangeal flexion/extension, and grip and tripod pinch strength. Further consensus recommendations were for the assessment of function using a region-specific, upper extremity patient-reported outcome measure (activity and participation), environmental factors, outcome expectation, and illness perception within the patient's unique environmental and social contexts. Treatment recommendations included the use of an orthosis during painful activities, a dynamic stability program (stable C posture, release of tight adductors, and strengthening of stabilizers), patient education, joint protection techniques, adaptive equipment, and functional-based intervention.

CONCLUSIONS

The findings describe the consensus of a group of experts and provide a clinical reference tool on the hand therapy assessment and treatment of nonsurgical thumb CMC joint OA.

Effect of a stabilization exercise program versus standard treatment for thumb carpometacarpal osteoarthritis: A randomized trial

STUDY DESIGN

Randomized, interventional trial with 1 year follow-up.

INTRODUCTION

Though recommended, evidence is lacking to support specific exercises to stabilize and strengthen the first carpometacarpal (CMC) joint for cases of osteoarthritis (OA).

PURPOSE OF THE STUDY

To determine in a naturalistic setting, whether standard treatment plus a home exercise program (ST+HEP) is more effective than standard treatment (ST) alone in improving Quick Disabilities of Arm, Shoulder and Hand (qDASH) scores, and secondarily, in other patient-centered (pain, function) and clinical outcomes (range of motion, strength).

METHODS

A total of 190 patients from a hand therapy practice in northwestern PA were enrolled by informed consent and randomized into ST or ST+HEP groups. Average age was 60 years, most were female (78%) with sedentary occupations most common (36%). ST group received orthotic interventions, modalities, joint protection education and adaptive equipment recommendations, while the ST+HEP group received a home exercise program in addition to ST for 6-12 months. Follow-up occurred at 3, 6, and 12 months. Outcomes included grip strength, pinch strength, range of motion (ROM), qDASH, Patient Specific Functional Scale (PSFS) and pain ratings. At the 6 month mark, all subjects could change groups if desired. Efficacy data analysis included both parametric and non-parametric tests. The threshold for statistical significance was 0.05 and adjusted for multiple comparisons.

RESULTS

Repeated measures ANOVA failed to show a statistically significant difference in strength and ROM assessments between treatment groups over the 12 month follow-up (P ≥ .398). Differences between groups did not exceed 13%. Both the ST and ST+HEP groups evidenced improvement over time in most patient-focused assessments (P ≤ .011), including improvements exceeding reported clinically important differences in pain with activity and PSFS scores. Scores for these measures were similar at each follow-up period (P ≥ .080) in each group. The presence of CTS exerted no effect on outcomes; longer treatment time was weakly related to poorer qDASH and PSFS scores initially. Of those enrolled, 48% of subjects completed the study.

CONCLUSIONS

The addition of a high-frequency home exercise program did not improve clinical or patient-centered outcomes more so than standard care in our sample however, study limitations are numerous. Both groups had decreased pain with activity and improved PSFS scores, meeting the established minimally clinically important difference (MCID) of each at 6 and 12 months. Adherence with the home program was poor and/or unknown.

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.

Eco-friendly screen printing of silver nanowires for flexible and stretchable electronics

Screen printing is a promising route towards high throughput printed electronics. Currently, the preparation of nanomaterial based conductive inks involves complex formulations with often toxic surfactants in the ink's composition, making them unsuitable as an eco-friendly printing technology. This work reports the development of a silver nanowire (AgNW) ink with a relatively low conductive particle loading of 7 wt%. The AgNW ink involves simple formulation and comprises a biodegradable binder and a green solvent with no toxic surfactants in the ink formulation, making it an eco-friendly printing process. The formulated ink is suitable for printing on a diverse range of substrates such as polydimethylsiloxane (PDMS), polyethylene terephthalate (PET), polyimide (PI) tape, glass, and textiles. By tailoring the rheological behaviour of the ink and developing a one-step post-printing process, a minimum feature size of 50 μm and conductivity as high as 6.70 × 106 S m-1 was achieved. Use of a lower annealing temperature of 150 °C makes the process suitable for plastic substrates. A flexible textile heater and a wearable hydration sensor were fabricated using the reported AgNW ink to demonstrate its potential for wearable electronic applications.

Digital rehabilitation for hand and wrist pain: a single-arm prospective longitudinal cohort study

Supplemental Digital Content is Available in the Text.

This study supports that a fully remote digital care program is feasible and able to promote high patient engagement in the telerehabilitation of patients with wrist and hand pain.

Introduction:

Wrist and hand represent the third most common body part in work-related injuries, being associated with long-term absenteeism. Telerehabilitation can promote access to treatment, patient adherence, and engagement, while reducing health care–related costs.

Objective:

Report the results of a fully remote digital care program (DCP) for wrist and hand pain (WP).

Methods:

A single-arm interventional study was conducted on individuals with WP applying for a DCP. Primary outcome was the mean change in the Numerical Pain Rating Scale after 8 weeks (considering a minimum clinically important change of 30%). Secondary outcomes were: disability (Quick Disabilities of the Arm, Shoulder, and Hand questionnaire), analgesic intake, surgery intention, mental health (patient health questionnaire [PHQ-9] and generalized anxiety disorder [GAD-7]), fear-avoidance beliefs (FABQ-PA), work productivity and activity impairment, and engagement.

Results:

From 189 individuals starting the DCP, 149 (78.8%) completed the intervention. A significant pain improvement was observed (51.3% reduction (2.26, 95% CI 1.73; 2.78)) and 70.4% of participants surpassing minimum clinically important change. This change correlated with improvements in disability (52.1%), FABQ-PA (32.2%), and activities impairment recovery (65.4%). Improvements were also observed in other domains: surgery intent (76.1%), mental health (67.0% in anxiety and 72.7% in depression), and overall productivity losses (68.2%). Analgesic intake decreased from 22.5% to 7.1%. Mean patient satisfaction score was 8.5/10.0 (SD 1.8).

Conclusions:

These findings support the feasibility and utility of a fully remote DCP for patients with WP. Clinically significant improvements were observed in all health-related and productivity-related outcomes, alongside very high patient adherence rates and satisfaction. This study strengthens that management of WP is possible through a remote DCP, decreasing access barriers and potentially easing health care expenditure.

Dynamic stabilization home exercise program for treatment of thumb carpometacarpal osteoarthritis: A prospective randomized control trial

STUDY DESIGN

Randomized control trial.

INTRODUCTION

Thumb carpometacarpal (CMC) osteoarthritis (OA) is a common cause of hand pain and disability. Standard conservative therapy (SCT) for thumb CMC OA includes an orthosis and instruction in joint protection, adaptive equipment, and pain relieving modalities. The dynamic stability home exercise (HE) program is complementary conservative therapy designed to strengthen the stabilizing muscles of the thumb CMC.

PURPOSE OF THE STUDY

To investigate whether the addition of HE to SCT (SCT+HE) was more effective at reducing pain and disability in thumb CMC OA compared to SCT alone.

METHODS

The study compared 2 groups: SCT and SCT+HE. The SCT group received SCT with in-home pain management instructions, joint protection strategies with adaptive equipment, and a hand-based thumb-spica orthosis. The SCT+HE group received HE program instructions for adductor stretching and opponens and first dorsal interosseous strengthening in addition to SCT. Our primary outcome measure was the numerical rating scale (NRS) with secondary outcome measures of QuickDASH (shortened Disabilities of the Arm, Shoulder and Hand questionnaire), range of motion, grip strength, and pinch strength. Outcome measurements were assessed at first visit, 6 weeks, and 6 months.

RESULTS

There was no statistical difference between the 2 groups for NRS and QuickDASH at 6 weeks (P = .28 and P = .36, respectively) or 6 months (P = .52 and P = .97, respectively). However, there was a statistically significant decrease in NRS and QuickDASH scores at 6 weeks and 6 months within both groups.

CONCLUSIONS

Both SCT and SCT+HE are effective at reducing pain and disability in OA of the thumb CMC joint. Neither therapy program was superior to the other at improving NRS or QuickDASH scores at 6-week or 6-month follow-up.

Comparison of finger kinematics between patients with hand osteoarthritis and healthy participants with and without joint protection programs

STUDY DESIGN

This is a cross-sectional, clinical observational study.

BACKGROUND

Finger range of motion (ROM) and functional performance are critical in many daily activities. Hand osteoarthritis (H-OA) is a prevalent disease that impairs both variables. Little quantitative research has been performed on finger kinematics during activities of daily living (ADLs) across health status and method of performance (with or without joint protection programs).

PURPOSE

The purpose of this research is to examine the effects of H-OA and method of performance on ROM in the thumb, index, and middle digits (flexion/extension and abduction/adduction) during ADLs.

METHODS

This study was conducted using 10 healthy participants (mean age: 28 years) and nine participants with H-OA (mean age: 72 years). All participants performed baseline ROM movements followed by 9 activities of daily living. These activities involved prehension type grasps and were performed with and without the recommended joint protection procedures specific to each task. Thumb IP and MCP, index distal interphalengeal (DIP) and proximal interphalengeal (PIP), and middle DIP and PIP joints were continuously recorded using an electromagnetic tracking system for ROM analysis.

RESULTS

Participants with H-OA had a statistically significant decrease in ROM when comparing values measured in the healthy cohort during active ROM (25° decrease) and ADL ROM (25° decrease) in the flex/ext direction. Similarly, following joint protection instruction, a statistically significant decrease in ROM was found during tasks in the flex/ext direction (healthy participant decrease in ROM: 17°, H-OA decrease in ROM:10°) CONCLUSIONS: This study demonstrated that people with hand arthritis move through a smaller arc of motion when performing some functional tasks as compared with the controls, and that with instruction on joint protection techniques, participants made significant changes in the amount of movement used to perform tasks, which supports a proof of principle of joint protection.

Incorporation of occupational based intervention into joint protection education for individuals with thumb carpometacarpal osteoarthritis: A case series

BACKGROUND

To our knowledge, the use of occupational performance in education on joint protection techniques has not been studied for individuals with thumb carpometacarpal (CMC) osteoarthritis.

PURPOSE

This case series was designed to investigate if occupation-based instruction inside the clinic was useful and found satisfactory as an educational tool for individuals with thumb CMC joint arthritis.

METHODS

Three participants with thumb CMC joint osteoarthritis performed washing, rinsing, and drying a dish, moving a pot and pan, maneuvering a laundry basket, and pouring from a pitcher during joint protection education in the therapy clinic with a skilled hand therapist in addition to routine treatment. Satisfaction with this intervention was assessed via a 3-question satisfaction survey. Pain with activity and function via the Thumb Disability Examination were assessed at baseline and a 4week follow up.

RESULTS

Patients in this study expressed satisfaction with the inclusion of the performance of occupations in their joint protection education in the clinic. Pain with activity improved by an average of 1.7/10 on a 10-point Numeric Pain Rating Scale and function improved by an average of 10.04 on the Thumb Disability Examination.

CONCLUSIONS

Although no causal relationships can be assumed in this study, hand therapists should consider adding occupation-based intervention as a component of patient education on joint protection for individuals with thumb CMC joint osteoarthritis.

The biomechanics of osteoarthritis in the hand: Implications and prospects for hand therapy

BACKGROUND

The unique anatomy of the human hand makes it possible to carefully manipulate tools, powerfully grasp objects, and even throw items with precision. These apparent contradictory functions of the hand, high mobility for manual dexterity vs high stability during forceful grasping, imply that daily activities impose a high strain on a relatively instable joint. This makes the hand susceptible to joint disorders such as osteoarthritis. Both systemic (eg, genetics, hormones) and mechanical factors (eg, joint loading) are important in the development of osteoarthritis, but the precise pathomechanism remains largely unknown. This paper focuses on the biomechanical factors in the disease process and how hand therapists can use this knowledge to improve treatment and research.

CONCLUSION

Multiple factors are involved in the onset and development of osteoarthritis in the hand. Comprehension of the biomechanics helps clinicians establish best practices for orthotics intervention, exercise, and joint protection programs even in de absence of clear evidence-based guidelines. The effect and reach of hand therapy for OA patients can be expanded substantially when intervention parameters are optimized and barriers to early referrals, access reimbursement, and adherence are addressed. Close and early collaboration between hand therapists and primary care, women's health, rheumatology, and hand surgery providers upon diagnosis, and with hand surgeons pre and postoperatively, combined with advances in the supporting science and strategies to enhance adherence, appear to be a promising way forward.

Dynamic stabilization of the painful thumb: A historical and evidence-informed synthesis

STUDY DESIGN

Expert opinion INTRODUCTION: Thumb carpometacarpal joint (CMC) osteoarthritis is a common condition seen in the hand therapy clinic. Prevalence is generally higher in females, and the percentage rises for post-menopausal females. Patients typically present with pain and functional difficulties. Conservative management is recommended before a surgical consult. Evidence is mounting that a dynamic stability modeled approach has a significant effect on pain and improving function.

PURPOSE

The purpose of this paper is two-fold: first, to present the history and development of a dynamic stabilization model for treatment of the patient with thumb CMC osteoarthritis (OA), and second, to provide expert clinical commentary and recommendations for the treatment of thumb CMC OA in light of the best available evidence.

METHODS

Expert clinical commentary is based on an extensive review of relevant literature.

RESULTS

The current literature and expert opinion supports an evidence-informed multimodal intervention: modalities, pain relief techniques, manual release, joint mobilizations as deemed necessary, neuromuscular re-education through proprioceptive exercises, and education in joint protection principles.

CONCLUSION

A rationale for a dynamic stabilization approach is presented. The unique anatomy of the thumb deserves finely tuned care based on high quality research. To advance our knowledge and clinical skills we must not become stagnant, but continue to generate high level evidence. The standard for future thumb CMC OA studies should be well-defined intervention parameters, consistent documentation, and the use of appropriate patient-rated outcome measures.

Convergent validity and responsiveness of the Canadian Occupational Performance Measure for the evaluation of therapeutic outcomes for patients with carpometacarpal osteoarthritis

STUDY DESIGN

This is a longitudinal, observational, multicenter, cohort study.

INTRODUCTION

Thumb carpometacarpal (CMC) osteoarthritis (OA) is associated with more pain and restrictions than other hand OA. The use of patient-identified occupational performance goals to guide hand therapy treatment and to measure clinical outcomes is fundamental for a patient-centered intervention. The COPM enables subjects to identify goals for hand therapy and engage in a subject-specific therapeutic process.

PURPOSE OF THE STUDY

The purpose of this study is to evaluate the convergent validity and responsiveness of the COPM to evaluate the relationship between the patient's self-perception and satisfaction of performance in everyday living and pain intensity, upper limb function, and manual ability.

METHODS

Eligible participants to multiple hand therapy centers were recruited. Outcomes measures (VAS scale, QuickDASH, MAM-36, and the COPM questionnaire) were measured at the baseline and 3 months after.

RESULTS

One hundred forty-five (n = 145) consecutive patients for five different hand rehabilitation centers with symptomatic thumb CMC OA were screened for eligibility criteria. COPM-P and COPM-S were the most responsive instruments, with an area under the curve of 0.88 (95% CI 0.79-0.96) and 0.88 (95% CI 0.80-0.96), respectively.

CONCLUSIONS

Although more investigation in this area is necessary to conclude that the COPM is the best option to evaluate the effectiveness of hand therapy interventions for thumb OA. The COPM focuses on function and occupation and, in comparison with others upper limb scales, does not require the use of another complementary scale for addressing both satisfaction and ADL status. COPM is an instrument with a good convergent validity and responsiveness to evaluate the relationship between the patient's self-perception and satisfaction in thumb CMC OA.

Patient satisfaction with the CMC controller: A cohort study

STUDY DESIGN

Cohort study.

INTRODUCTION

The evidence specific to understanding patient satisfaction, preference and the effects on occupational performance using a CMC orthosis is sparse.

PURPOSE OF THE STUDY

The main purpose of this study was to determine patient satisfaction, aspects of the orthotic preference, and the effect on pain and function of the CMC Controller Plus neoprene orthotic device.

METHODS

This research was conducted at two outpatient clinics located in Pennsylvania and Florida during 2019. The subjects of this study included any individuals referred to one of two participating hand therapy facilities with either a primary or secondary diagnosis of thumb CMC joint arthritis or present with this diagnosis as a comorbidity. The CMC Controller Plus orthosis (Hely & Weber) was provided to each patient by the treating therapist at no cost to the patient after the patient agreed to take part in the study. None of the patients received hand therapy treatment for the CMC pain; the only intervention provided was the CMC Controller Plus.

RESULTS

The CMC Controller Plus orthosis improved the patients' functional status and reduced their pain. The effect size for the change in function was large (1.29) compared to the effect size for the reduction in pain which approached moderate at 0.49.

DISCUSSION

The CMC Controller Plus orthosis improved the patient's functional status by 52% and reduced their pain by 29%.

CONCLUSION

The results were both statistically and clinically significant.

Comparison of efficacy of fluidotherapy and paraffin bath in hand osteoarthritis: A randomized controlled trial

Objectives

This study aims to compare the efficacy of paraffin bath therapy and fluidotherapy on pain, hand muscle strength, functional status, and quality of life (QoL) in patients with hand osteoarthritis (OA).

Patients and methods

This prospective randomized controlled study included 77 patients (8 males, 69 females; mean age: 63.1±10.3 years; range 39 to 88 years) with primary hand OA who applied between July 2017 and March 2018. The patients were randomized into two groups with the sealed envelope method: Paraffin bath therapy (20 min, one session per day, for two weeks) was applied for 36 patients whereas 41 patients received fluidotherapy for the same period. The pain severity of the patients, both at rest and during activities of daily living (ADL) within the last 48 hours was questioned and scored using Visual Analog Scale. Duruöz Hand Index (DHI) was used to evaluate hand functions. Gross grip strength was measured using Jamar dynamometer whereas fine grip strength was measured using pinch meter in three different positions (lateral pinch, tip pinch, and palmar pinch). The 36-Item Short Form (SF-36) was used to analyze the QoL. All measurements were performed before, immediately after, and three months after treatment.

Results

Improvement was observed in pain score at rest and during ADL, DHI scores, gross and fine grip strengths, and SF-36 subscores in both groups after treatment. However, no significant difference was observed between the groups.

Conclusion

Both fluidotherapy and paraffin bath therapy have been found to have positive effects on pain, hand muscle strength, functional status, and QoL in the treatment of hand OA. However, no superiority was observed between the two treatment modalities.

Automated 3D-printed finger orthosis versus manual orthosis preparation by occupational therapy students: Preparation time, product weight, and user satisfaction

STUDY DESIGN

Intra-subject cross-sectional study.

INTRODUCTION

Upper limb injuries often require wearing an orthosis. Today, orthoses are custom-made by the clinician or purchased as an off-shelf product. Although 3D printing is a popular solution, the design and adjustment of an orthosis model according to patient-specific anatomy requires technical expertise, often unavailable to the clinicians.

PURPOSE OF THE STUDY

(1) To create a software that receives input of anatomic dimensions of the finger and automatically adjusts an orthosis model for patient-specific 3D printing and (2) to compare preparation time, product weight, and user satisfaction of occupational therapy students between the manual method and the automatic 3D printing method.

METHODS

A custom code allows the user to measure five anatomic measurements of the finger. The code adjusts a swan-neck orthosis model according to the patient-specific measurements, and a fitted resized 3D-printable file is produced. We recruited 36 occupational therapy students (age 25.4 ± 1.9 years). They prepared two swan-neck orthoses for a finger of a rubber mannequin: one manually using a thermoplastic material and the other by 3D printing. The preparation time and orthosis weight were measured, and the subjects filled out a user satisfaction questionnaire.

RESULTS

The weight of the 3D-printed orthosis was significantly lower than that of the manual orthosis; however, the preparation time was longer. The subjects were more satisfied with the fit, esthetics, overall process, and product of the 3D-printed orthosis.

CONCLUSION

The creation of an automated software for the patient-specific adjustment of orthoses for 3D printing can be the missing link for integration of 3D printing in the clinics.

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.

Integrating transcriptome-wide association study and mRNA expression profile identified candidate genes related to hand osteoarthritis

Background

Osteoarthritis (OA) is a common skeletal system disease that has been partially attributed to genetic factors. The hand is frequently affected, which seriously affects the patient’s quality of life. However, the pathogenetic mechanism of hand osteoarthritis (hand OA) is still elusive.

Methods

A genome-wide association study (GWAS) summary of hand OA was obtained from the UK Biobank dataset, which contains data from a total of 452,264 White British individuals, including 37,782 OA patients. The transcriptome-wide association study (TWAS) of hand OA was performed using FUnctional Summary-based ImputatiON (FUSION) with the skeletal muscle and blood as gene expression references. The significant genes identified by TWAS were further subjected to gene set enrichment analysis (GSEA) with the Database for Annotation, Visualization and Integrated Discovery (DAVID) tool. Furthermore, we compared the genes and gene sets identified by our TWAS with that of a knee OA mRNA expression profile to detect the genes and gene sets shared by TWAS and mRNA expression profiles in OA. The mRNA expression profiles of 18 normal knee cartilages and 20 OA knee cartilages were acquired from the Gene Expression Omnibus database (accession number: GSE114007).

Results

TWAS identified 177 genes with P < 0.05 for the skeletal muscle, including ANKRD44 (P = 0.0001), RIC3 (P = 0.0003), and AC005154.6 (P = 0.0004). TWAS identified 423 genes with P < 0.05 for the blood, including CRIM1 (P = 0.0002), ZNF880 (P = 0.0002), and NCKIPSD (P = 0.0003). After comparing the results of the TWAS to those of the mRNA expression profiling of OA, we identified 5 common genes, including DHRS3 (log2fold = − 1.85, P = 3.31 × 10^− 9) and SKP2 (log2fold = 1.36, P = 1.62 × 10^− 8). GSEA of TWAS identified 51 gene ontology (GO) terms for hand OA, for example, protein binding (P = 0.0003) and cytosol (P = 0.0020). We also detected 6 common GO terms shared by TWAS and mRNA expression profiling, including protein binding (P_TWAS = 2.54 × 10^− 4, P_mRNA = 3.42 × 10^− 8), extracellular exosome (P_TWAS = 0.02, P_mRNA = 1.18 × 10^− 4), and cytoplasm (P_TWAS = 0.0183, P_mRNA = 0.0048).

Conclusion

In this study, we identified 5 candidate genes and 6 GO terms related to hand OA, which may help to uncover the pathogenesis of hand OA. It should be noted that the possible difference in the gene expression profiles between hand OA and knee OA may affect our study results, which should be interpreted with caution.

The effect of orthoses on the kinematics of the trapeziometacarpal, scaphotrapeziotrapezoidal, and radioscaphoid joints

The in vivo effect of four different types of thumb and thumb-wrist orthoses on the three-dimensional kinematics of the trapeziometacarpal (TMC), scaphotrapeziotrapezoidal (STT) and radioscaphoid joints was quantified using computed tomography (CT). Eighteen healthy female volunteers were recruited. The dominant hand of each subject was scanned in four thumb and wrist positions, each in three conditions: without orthosis, with a thumb orthosis (Push Ortho and immediate fitting, IMF) and with a thumb-wrist orthosis (Ligaflex Manu and IMF). CT images were analyzed and rotations relative to the more proximal bone were expressed in a joint-specific coordinate system. Without orthosis, the largest STT rotations were observed during radioulnar deviation of the wrist and the STT range of motion (ROM) was significantly lower during wrist flexion-extension. All tested orthoses caused a significant reduction of the ROM at each joint compared to free motion. Significant differences in movement reduction were observed between prefabricated and IMF orthoses.The IMF thumb-wrist outperformed the Ligaflex Manu in terms of immobilization of the radioscaphoid joint. In addition, the IMF thumb orthosis immobilized the TMC joint significantly better during thumb abduction and adduction than the Push Ortho. We found that different types of thumb and thumb-wrist orthotics are effective in reducing joint mobility. While this reduction tends to be higher using IMF compared to prefabricated orthoses, this effect is only significant for the radioscaphoid and TMC joint. The finding that thumb movements do not induce large STT rotations suggests that the thumb does not need to be immobilized in case of isolated STT osteoarthritis.

Self-Efficacy, Pain Intensity, Rheumatic Disease Duration, and Hand Functional Disability on Activities of Daily Living

BACKGROUND

Knowledge regarding the possible influence of self-efficacy, pain intensity and disease duration on hand functional disability could promote new intervention strategies for activities of daily living (ADLs) in patients with rheumatic disease (RD). These approaches could prevent the health problems and socioeconomic costs associated with these diseases.

OBJECTIVE

The aims of this study were to evaluate if there are differences between the levels of perceived self-efficacy, pain intensity and disease duration among people with RD and non-RD diseases, and to analyze if hand functional disability in ADLs is related to self-efficacy, pain intensity and disease duration in a sample of patients with RD.

METHODS

A multicenter, observational, cross-sectional study was conducted on a total sample of 335 participants over 50 years old (176 patients with RD and 159 individuals with non-RD). The Duruöz Hand Index, the General Perceived Self-Efficacy Scale, the Rheumatic Diseases Self-Efficacy Scale (RDS-ES), the Visual Analog Scale (VAS), and the mean time of evolution in years of the disease (disease duration) were used to analyze the possible relationships surrounding hand functional disability in ADLs.

RESULTS

The comparison analysis showed significant differences between the RD/non-RD sample for the General Perceived Self-Efficacy Scale, RDS-ES, and VAS scores (p < .001). The multiple regression results showed that age, General Perceived Self-Efficacy Scale scores, RDS-ES scores, VAS scores, and disease duration (or a combination of some of them) explained the variability of hand functional disability in almost 68% of kitchen tasks, 44% of dressing tasks, 46% of hygiene and other tasks, and 47% of office tasks.

DISCUSSION

Our study shows that general and domain-specific self-efficacy, pain intensity, and disease duration are predictors of the dimensions of hand functional disability in patients with RD. Early evaluation of these components with an interdisciplinary approach would help to manage hand disability properly.

Conservative therapeutic interventions for osteoarthritic finger joints: A systematic review

STUDY DESIGN

Systematic review.

INTRODUCTION

Hand osteoarthritis (OA) is a chronic and disabling disease causing pain and functional limitations in approximately 54%-67% of the adult population aged 55 years and older.

PURPOSE OF THE STUDY

The objective of the study is to evaluate the evidence supporting conservative therapeutic interventions for the treatment of OA finger joints.

METHODS

Eighteen studies dated between 1979 and 2016 were identified meeting the inclusion criteria. They were analyzed based on Structured Effectiveness for Quality Evaluation of a Study, level of evidence, and effect size.

RESULTS AND CONCLUSIONS

The current evidence varies in quality and effect sizes but generally supports the use of active range of motion and resistive exercises, joint protection, electromagnetic therapy, paraffin wax, and balneotherapy (combined and/or not combined with mud packs and magnetotherapy), and distal interphalangeal orthoses as effective treatment interventions for individuals with OA finger joints.

Effect of immobilization of metacarpophalangeal joint in thumb carpometacarpal osteoarthritis on pain and function. A quasi-experimental trial

STUDY DESIGN

A quasi-experimental trial.

INTRODUCTION

Orthoses are effective to decrease pain and improve function in patients with carpometacarpal osteoarthritis (CMC OA). However, current research does not support one design of an orthosis as more effective and/or more favorable than another.

PURPOSE OF THE STUDY

The aim of this study was to compare the effectiveness of 2 different static orthosis on pain and functional abilities on CMC OA.

METHODS

Eighty-four patients, 91.7% females (mean ± standard deviation age, 60.1 ± 9.6 years), with thumb CMC OA were randomized into 1 of 2 groups. For group A, a Ballena orthotic was constructed, and for group B, a Colditz orthotic was constructed. Both static orthoses were worn for 3 months. The outcome measures included pain with activity measured with the visual analog scale and functional abilities assessed with the Disabilities of the Arm, Shoulder and Hand.

RESULTS

Both orthoses improved pain level and functional abilities (F_[1.0] = 413.327 and F_[1.0] = 211.742; both P < .001). There was no statistically significant difference between 2 groups regarding to pain recovery and functional improvement (F_[1.0] = 0.075 and F_[1.0] = 7.248; both P > .05).

DISCUSSION

The main purpose was to compare the effect of 2 different thermoplastic thumb orthoses. Previous studies support the use of CMC orthoses to decrease hand pain and improve hand function, but different orthoses have been described and in most cases, orthotic interventions were accompanied by other medical treatments.

CONCLUSIONS

A clinically significant reduction in pain intensity and improvement in functional abilities was achieved with both orthoses in patients with thumb CMC OA.

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.

Exercise Therapy in Addition to an Orthosis Reduces Pain More Than an Orthosis Alone in Patients With Thumb Base Osteoarthritis: A Propensity Score Matching Study

OBJECTIVE

To compare the effect of exercises and orthotics with orthotics alone on pain and hand function in patients with first carpometacarpal joint (CMC-1) osteoarthritis (OA) and to predict outcomes on pain and hand function of exercises and orthotics.

DESIGN

Prospective cohort study with propensity score matching.

SETTING

Data collection took place in 13 outpatient clinics for hand surgery and hand therapy in The Netherlands.

PARTICIPANTS

A consecutive, population-based sample of patients with CMC-1 OA (N=173) was included in this study, of which 84 were matched on baseline demographics and baseline primary outcomes.

INTERVENTIONS

Exercises and orthotics versus orthotics alone.

MAIN OUTCOME MEASURES

Primary outcomes included pain and hand function at 3 months, measured using visual analog scale (VAS, 0-100) and the Michigan Hand Outcomes Questionnaire (MHQ, 0-100).

RESULTS

A larger decrease in VAS pain at rest (11.1 points difference; 95% confidence interval, 1.9-20.3; P=.002) and during physical load (22.7 points difference; 95% confidence interval, 13.6-31.0; P<.001) was found in the exercise + orthotic group compared to the orthotic group. In addition, larger improvement was found for the MHQ subscales pain, work performance, aesthetics, and satisfaction in the exercise + orthotic group. No differences were found on other outcomes. Baseline scores of metacarpophalangeal flexion, presence of scaphotrapeziotrapezoid OA, VAS pain at rest, heavy physical labor, and MHQ total predicted primary outcomes for the total exercise + orthotic group (N=131).

CONCLUSIONS

Non-surgical treatment of patients with CMC-1 OA should include exercises, since there is a relatively large treatment effect compared to using an orthosis alone. Future research should study exercises and predictors in a more standardized setting to confirm this finding.

A Scoping Review of Joint Protection Programs for People with Hand Arthritis

Background:

Joint Protection (JP) can be enhanced by incorporating recent evidence and innovations in collaboration with people with hand arthritis to be salient, useful and effectively implemented.

Objective:

The purpose of this study is to map the current research on JP principles and guide future research on JP programs for the management of hand arthritis.

Methods:

A search was performed in 4 databases (PubMed, EMBASE, Google SCHOLAR, CINHAL) from January 1990 to February 2017. A Grey literature was also conducted through the Google web search engine. A combination of search terms was used such as hand osteoarthritis, rheumatoid arthritis, joint protection and/or self-management strategies.

Results:

Our search found 8,788 citations in which 231 articles were deemed relevant and after duplication 111 articles were retrieved for a full-text review. In total, 40 articles were eligible for data extraction. The majority of the articles were randomized controlled trials (RCTs), systematic reviews and overviews of reviews that investigated joint protection for hand arthritis. Joint protection was tested mostly in rheumatoid arthritis (RA) population and to a lesser extent on hand osteoarthritis and was provided mainly by an occupational therapist.

Conclusion:

This review synthesized and critically examined the scope of JP for the management of hand arthritis and found that RCTs, systematic reviews and overviews of reviews constituted two-thirds of the current body of literature. Furthermore, it identified a lack of clarity regarding the specific elements of joint protection programs used in clinical studies.

Description and Clinical Assessment of the Bone Block Tendon Interposition Technique for the Management of Thumb Carpometacarpal Joint Osteoarthritis

BACKGROUND

Pellegrini's surgical technique is the most useful for thumb carpometacarpal joint osteoarthritis. The purpose of this paper is to describe the technique of a modified version using a bone block in the tunnel through which the flexor carpi radialis tendon is passed (BBTI).

METHODS

Case series of patients diagnosed with osteoarthritis of the thumb carpometacarpal joint, in stage II or higher based on Eaton's classification, that were intervened using the BBTI technique for a 2-year period. Grip and pinch strength, range of motion, and 1-2 metacarpal angle were evaluated. Pain and function were measured using the visual analogue scale and the Disabilities of the Arm, Shoulder and Hand (DASH) scale.

RESULTS

The study included 16 cases in 14 patients (11 women and 3 men), with an average age of 55.7 ± 7.1 years. Encouraging results were obtained, with an average DASH score of 24.3 ± 17.9 and a minimum VAS pain score. A total of 58% showed a grip strength of over 80% and the postoperative movement was equivalent to the contralateral limb. No cases of infection were reported, and only two minor complications were observed.

CONCLUSIONS

The BBTI technique is a surgical option that incorporates an interference screw, offering good functional results for managing osteoarthritis of the thumb carpometacarpal joint, with a similar complication rate to that of the original technique.

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.

Improved Hand Function, Self-Rated Health, and Decreased Activity Limitations: Results After a Two-Month Hand Osteoarthritis Group Intervention

OBJECTIVE

To evaluate the effects on hand function, activity limitations, and self-rated health of a primary care hand osteoarthritis (OA) group intervention. Hand OA causes pain, impaired mobility, and reduced grip force, which cause activity limitations. OA group interventions in primary care settings are sparsely reported.

METHODS

Sixty-four individuals with hand OA agreed to participate; 15 were excluded due to not fulfilling the inclusion criteria. The 49 remaining (90% female) participated in an OA group intervention at a primary care unit with education, paraffin wax bath, and hand exercise over a 6-week period. Data were collected at baseline, end of intervention, and after 1 year. Instruments used were the Grip Ability Test (GAT), the Signals of Functional Impairment (SOFI), dynamometry (grip force), hand pain at rest using a visual analog scale (VAS), the Patient-Specific Functional Scale (PSFS), the Quick Disabilities of the Arm, Shoulder, and Hand (Quick-DASH), and the EuroQol VAS (EQ VAS). Data were analyzed using nonparametric statistics.

RESULTS

Hand function, activity limitation, and self-rated health significantly improved from baseline to end of intervention, grip force (right hand: P < 0.001; left hand: P = 0.008), SOFI (P = 0.011), GAT (P < 0.001), hand pain at rest (P < 0.001), PSFS (1: P = 0.008, 2: P < 0.001, and 3: P = 0.004), Quick-DASH (P = 0.001), and EQ VAS (P = 0.039), and the effects were sustained after 1 year.

CONCLUSION

The hand OA group intervention in primary care improves hand function, activity limitation, and self-rated health. The benefits are sustained 1 year after completion of the intervention.

Trapeziometacarpal joint osteoarthritis: a prospective trial on two widespread conservative therapies

Introduction

The trapeziometacarpal (TMC) joint osteoarthritis (OA) is at the origin of important secondary functional disability to pinch as well as a painful grip. Several conservative therapies are often considered in the early stages of TMC OA to decrease pain, recover function and slow the evolution of OA. They include massage therapy, heat applications, stretching of the first web span and assisted mobilization of the TMC joint. However, as with other arthritic joints, many physicians often suggest administering intra-articular corticosteroids. The aim of this study was to assess the effect of 10 sessions of physiotherapy versus a single corticoid intra-articular injection. Both treatments were associated with TMC splinting.

Methods

Two groups of twenty-five patients received either physiotherapy or a corticoid injection. They were followed over a one-year period. All of them were assessed for pain, function, strength at 2, 6 and 12 months and overall satisfaction at the end of the study.

Results

With the infiltrative therapy, the parameters improve more quickly, whereas patients treated with physiotherapy show longer persistence regarding remission of pain. The final functional evaluation scores at one year are similar to pretreatment scores.

Conclusion

In early stages of TMC OA, corticosteroids articular injections and physiotherapy treatments can improve the painful symptoms but treatment with corticosteroids is faster. Although hand functions return to average scores similar to those of pre-treatment, physiotherapy program is associated with a longer remission of pain.

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.

Linking ICF components to outcome measures for orthotic intervention for CMC OA: A systematic review

STUDY DESIGN

Systematic review.

INTRODUCTION/PURPOSE

The purpose of this study was to systematically review outcome measures used for assessment of orthotic intervention in the conservative management of thumb carpometacarpal osteoarthritis to determine if they characterize International Classification of Functioning, Disability, and Health (ICF) components. The determinants of patient satisfaction regarding the orthotic intervention were also extracted from the studies.

METHODS

A comprehensive literature search was conducted. Outcome measures in the included studies were linked to the ICF. Determinants of patient satisfaction regarding the orthotic intervention were also extracted.

RESULTS

Nine studies met inclusion criteria. Eight (47.1%) outcomes were linked to body structures and functions, 8 (47.1%) to activity limitations and participation restrictions, and 1 (5.9%) outcome fell into the nondefinable quality of life category. Four studies assessed patient satisfaction.

DISCUSSION/CONCLUSIONS

This systematic review on orthotic intervention for thumb carpometacarpal osteoarthritis found opportunities related to assessment and outcome measures when present studies are linked to the ICF.

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.

Short-term efficacy of paraffin therapy and home-based exercise programs in the treatment of symptomatic hand osteoarthritis

Objectives

This study aims to investigate the effects of a home-based exercise program in combination with paraffin therapy on pain, functional status, grip strength, and quality of life (QoL) and to compare the outcomes of these two treatment modalities.

Patients and methods

This prospective, single-blind, randomized-controlled study included a total of 61 patients (8 males, 53 females, mean age 59.22 years; range, 35 to 78 years) who were diagnosed with hand osteoarthritis (HOA) according to the American College of Rheumatology criteria between November 2016 and February 2017. The first group (group 1) (n=31) received paraffin therapy + home-based exercise program and the second group (group 2) (n=30) received home-based exercise program alone. All patients were assessed using the Visual Analog Scale (VAS), Australian/Canadian (AUSCAN) Osteoarthritis Hand Index, Health Assessment Questionnaire (HAQ), Hand Grip Strength (HGS), and Finger Pinch Strength (FPS) at baseline and at two and six weeks after the intervention.

Results

In group 1, there were statistically significant improvements in all parameters at two and six weeks (p<0.05). Statistically significant differences were observed in the HGS and AUSCAN Osteoarthritis Hand Index scores in group 2 at two and six weeks (p<0.05). Inter-group analysis showed statistically significant differences in favor of group 1 in the VAS, HAQ, AUSCAN Osteoarthritis Hand Index, HGS, and FPS scores at two and six weeks compared to baseline scores (p<0.05).

Conclusion

Paraffin therapy combined with home-based exercise program in patients with symptomatic HOA provides effective pain control and is effective in improving functional status, HGS, FPS, and QoL in short term.

Sensorimotor performance and function in people with osteoarthritis of the hand: A case-control comparison

OBJECTIVES

To determine whether hand left/right judgements, tactile acuity, and body perception are impaired in people with hand OA. To examine the relationships between left right judgements, tactile acuity and hand pain. To explore the relationships between sensorimotor measures (left/right judgements and tactile acuity) and measures of hand function in people with hand OA.

METHODS

Twenty patients with symptomatic hand OA and 19 healthy pain-free controls undertook a hand left/right judgment task, a control left/right judgement task, two-point discrimination (TPD) threshold testing (assessing tactile acuity), a neglect-like symptoms questionnaire (assessing body perception) and several established measures of hand function.

RESULTS

Neglect-like symptoms were experienced more frequently in the hand OA group (P < 0.05). People with hand OA were slower (P < 0.05) and less accurate (P < 0.05) in the hand left/right judgement task when compared to healthy controls, with no significant difference in the control task. Significant associations were found between hand left/right judgement reaction time and pain intensity (P < 0.05) and accuracy and pain intensity (P < 0.05). TPD was not different between groups, and no correlation was found between TPD and left/right judgement performance. No association was found between left/right judgement performance and measures of hand function (all P > 0.05). However, TPD (tactile acuity) was related to several measures of hand function (all P < 0.05).

CONCLUSION

People with hand OA had more frequent neglect-like symptoms and were slower and less accurate compared to healthy controls at hand left/right judgments, which was indicative of disrupted working body schema. Future studies may wish to examine whether interventions targeting sensorimotor dysfunction are effective at reducing pain and improving hand function and dexterity in people with hand OA.

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.

A Systematic Review of Different Implants and Approaches for Proximal Interphalangeal Joint Arthroplasty

BACKGROUND

Outcomes after implant arthroplasty for primary degenerative and posttraumatic osteoarthritis of the proximal interphalangeal joint were different according to the implant design and surgical approach. The purpose of this systematic review was to evaluate outcomes of various types of implant arthroplasty for proximal interphalangeal joint osteoarthritis, with an emphasis on different surgical approaches.

METHODS

The authors searched all available literature in the PubMed and EMBASE databases for articles reporting on outcomes of implant arthroplasty for proximal interphalangeal joint osteoarthritis. Data collection included active arc of motion, extension lag, and complications. The authors combined the data of various types of surface replacement arthroplasty into one group for comparison with silicone arthroplasty.

RESULTS

A total of 849 articles were screened, yielding 40 studies for final review. The mean postoperative arc of motion and the mean gain in arc of motion of silicone implant with the volar approach were 58 and 17 degrees, respectively, which was greater than surface replacement implant with the dorsal approach at 51 and 8 degrees, respectively. The mean postoperative extension lag of silicone implant with the volar approach and surface replacement with the dorsal approach was 5 and 14 degrees, respectively. The revision rate of silicone implant with the volar approach and surface replacement with the dorsal approach was 6 percent and 18 percent at a mean follow-up of 41.2 and 51 months, respectively.

CONCLUSION

Silicone implant with the volar approach showed the best arc of motion, with less extension lag and fewer complications after surgery among all the implant designs and surgical approaches.

Differences in orthotic design for thumb osteoarthritis and its impact on functional outcomes: A scoping review

BACKGROUND

Orthoses are a well-known intervention for the treatment of thumb osteoarthritis; however, there is a multitude of orthotic designs and not enough evidence to support the efficacy of specific models.

OBJECTIVE

To examine the influence of different orthoses on pain, hand strength, and hand function of patients with thumb osteoarthritis.

STUDY DESIGN

Literature review.

METHODS

A scoping literature review of 14 publications reporting orthotic interventions for patients with thumb osteoarthritis was conducted. Functional outcomes and measures were extracted and analyzed.

RESULTS

In total, 12 studies reported improvements in pain and hand strength after the use of thumb orthoses. Comparisons between different orthotic designs were inconclusive.

CONCLUSION

The use of orthoses can decrease pain and improve hand function of patients with thumb osteoarthritis; however, the effectiveness of different orthoses still needs support through adequate evidence. Clinical relevance Multiple orthoses for thumb osteoarthritis are available. Although current studies support their use to improve pain and hand function, there is no evidence to support the efficacy of specific orthotic designs. Improved functional outcomes can be achieved through the use of short orthoses, providing thumb stabilization without immobilizing adjacent joints.

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.

Effectiveness of a fine motor skills rehabilitation program on upper limb disability, manual dexterity, pinch strength, range of fingers motion, performance in activities of daily living, functional independency, and general self-efficacy in hand osteoarthritis: A randomized clinical trial

STUDY DESIGN

A randomized clinical trial.

INTRODUCTION

Rehabilitation treatments for improving fine motor skills (FMS) in hand osteoarthritis (HOA) have not been well explored yet.

PURPOSE OF THE STUDY

To assess the effectiveness of a rehabilitation program on upper limb disability, independence of activities of daily living (ADLs), fine motor abilities, functional independency, and general self-efficacy in older adults with HOA.

METHODS

About 45 adults (74-86 years) with HOA were assigned to an experimental group for completing an FMS intervention or a control group receiving conventional occupational therapy. Both interventions were performed 3 times/wk, 45 minutes each session, during 8 weeks. Upper limb disability, performance in ADLs, pinch strength, manual dexterity, range of fingers motion, functional independency, and general self-efficacy were assessed at baseline, immediately after treatment, and after 2 months of follow-up.

RESULTS

FMS group showed significant improvements with a small effect size on manual dexterity (P ≤ .034; d ≥ 0.48) and a moderate-high effect on range of index (P ≤ .018; d ≥ 0.58) and thumb (P ≤ .027; d ≥ 0.39) motion. The control group showed a significant worse range of motion over time in some joints at the index (P ≤ .037; d ≥ 0.36) finger and thumb (P ≤ .017; d ≥ 0.55).

CONCLUSIONS

A rehabilitation intervention for FMS may improve manual dexterity and range of fingers motion in HOA, but its effects on upper limb disability, performance in ADLs, pinch strength, functionality, and self-efficacy remain uncertain. Specific interventions of the hand are needed to prevent a worsening in range of finger motion.

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.
