Is progressive early digit mobilization intervention beneficial for patients with external fixation of distal radius fracture? A pilot randomized controlled trial

Supervised exercise therapy program vs non-supervised exercise therapy program after distal radius fracture: A systematic review and meta-analysis

BACKGROUND

It is an updated systematic review with meta-analysis that compared supervised exercise therapy (SET) vs non-supervised exercise therapy (NSET) programs for patients with distal radius fracture.

PURPOSE

The purpose of this systematic review is to appraise the current literature to determine if SET program is more effective than a NSET program for pain relief, improvement of range of movement, function and grip strength, both in the short or medium term for patients following distal radius fractures.

STUDY DESIGN

Systematic review.

METHODS

The following electronic databases were searched: Medline/Pubmed, PEDro, Cinahl, Embase, CENTRAL, and Lilacs. PICOT strategy was used for trial selection. The searches were conducted on August 22, 2021, and May 26, 2022. Two researchers performed an independent search for papers from the references of the chosen trials. Grading of Recommendations, Assessment, Development and Evaluations (GRADE) was used for assessing the quality of evidence.

RESULTS

The search strategy identified 2786 potentially eligible studies and 15 studies met our inclusion criteria. The results did not show that the SET program was more effective than the NSET program for all outcomes, in both terms for patients after distal radius fractures. GRADE showed that all analyses presented very low-quality evidence.

CONCLUSIONS

Even the results showing there was no difference between the two programs analyzed, the available evidence for randomized controlled trials was insufficient to support these results.

Effect of Time-To-Surgery on Distal Radius Fracture Outcomes: A Systematic Review

PURPOSE

It remains unclear whether time-to-surgery for distal radius fractures affects clinical, functional, or radiographic outcomes or health care costs/use. This systematic review investigated the outcomes of early versus delayed surgery for closed, isolated distal radius fractures in adult patients.

METHODS

A comprehensive search of MEDLINE, Embase, and CINAHL databases was completed for all original case series, observational studies, and randomized controlled trials reporting clinical outcomes of both early and delayed surgically-treated distal radius fractures from database inception to July 01, 2022. A consistent threshold of two weeks was used to define early versus delayed treatment arms.

RESULTS

Nine studies, including 16 intervention arms and 1,189 patients (858 early, 331 delayed), were included. Mean age was 58 years (range, 33-76). At more than one year, the frequency-weighted mean Disabilities of the Arm, Shoulder, and Hand score was 4 in the early group (n = 208; range, 1-17) and 21 in the delayed group (n = 181; range, 4-27). Range of motion, grip strength, and radiographic outcomes were comparable. The pooled mean complication rate (7% vs 5%) and revision rate (3.6% vs 1%) were very low in both groups.

CONCLUSIONS

A delay in time-to-surgery greater than two weeks for distal radius fractures may be associated with inferior patient-reported outcomes. Early surgery was associated with improved long-term Disabilities of the Arm, Shoulder, and Hand scores. On the basis of the available evidence, range of motion, grip strength, and radiographic outcomes are similar. The complication and revision rates were very low in both groups and comparable.

The clinician's guide to prevention and treatment of osteoporosis

Osteoporosis is the most common metabolic bone disease in the USA and the world. It is a subclinical condition until complicated by fracture(s). These fractures place an enormous medical and personal burden on individuals who suffer from them and take a significant economic toll. Any new fracture in an adult aged 50 years or older signifies imminent elevated risk for subsequent fractures, particularly in the year following the initial fracture. What a patient perceives as an unfortunate accident may be seen as a sentinel event indicative of bone fragility and increased future fracture risk even when the result of considerable trauma. Clinical or subclinical vertebral fractures, the most common type of osteoporotic fractures, are associated with a 5-fold increased risk for additional vertebral fractures and a 2- to 3-fold increased risk for fractures at other sites. Untreated osteoporosis can lead to a vicious cycle of recurrent fracture(s), often resulting in disability and premature death. In appropriate patients, treatment with effective antifracture medication prevents fractures and improves outcomes. Primary care providers and medical specialists are critical gatekeepers who can identify fractures and initiate proven osteoporosis interventions. Osteoporosis detection, diagnosis, and treatment should be routine practice in all adult healthcare settings. The Bone Health and Osteoporosis Foundation (BHOF) - formerly the National Osteoporosis Foundation - first published the Clinician's Guide in 1999 to provide accurate information on osteoporosis prevention and treatment. Since that time, significant improvements have been made in diagnostic technologies and treatments for osteoporosis. Despite these advances, a disturbing gap persists in patient care. At-risk patients are often not screened to establish fracture probability and not educated about fracture prevention. Most concerning, the majority of highest risk women and men who have a fracture(s) are not diagnosed and do not receive effective, FDA-approved therapies. Even those prescribed appropriate therapy are unlikely to take the medication as prescribed. The Clinician's Guide offers concise recommendations regarding prevention, risk assessment, diagnosis, and treatment of osteoporosis in postmenopausal women and men aged 50 years and older. It includes indications for bone densitometry as well as fracture risk thresholds for pharmacologic intervention. Current medications build bone and/or decrease bone breakdown and dramatically reduce incident fractures. All antifracture therapeutics treat but do not cure the disease. Skeletal deterioration resumes sooner or later when a medication is discontinued-sooner for nonbisphosphonates and later for bisphosphonates. Even if normal BMD is achieved, osteoporosis and elevated risk for fracture are still present. The diagnosis of osteoporosis persists even if subsequent DXA T-scores are above - 2.5. Ongoing monitoring and strategic interventions will be necessary if fractures are to be avoided. In addition to pharmacotherapy, adequate intake of calcium and vitamin D, avoidance of smoking and excessive alcohol intake, weight-bearing and resistance-training exercise, and fall prevention are included in the fracture prevention armamentarium. Where possible, recommendations in this guide are based on evidence from RCTs; however, relevant published data and guidance from expert clinical experience provides the basis for recommendations in those areas where RCT evidence is currently deficient or not applicable to the many osteoporosis patients not considered for RCT participation due to age and morbidity.

Overall Effects and Moderators of Rehabilitation in Patients With Wrist Fracture: A Systematic Review

OBJECTIVE

Wrist fractures constitute the most frequently occurring upper limb fracture. Many individuals report persistent pain and functional limitations up to 18 months following wrist fracture. Identifying which individuals are likely to gain the greatest benefit from rehabilitative treatment is an important research priority. This systematic review aimed to summarize effectiveness of rehabilitation after wrist fracture for pain and functional outcomes and identify potential effect moderators of rehabilitation.

METHODS

A comprehensive search of 7 databases (including MEDLINE, EMBASE, and the Physiotherapy Evidence Database) was performed for randomized controlled trials involving adults >50 years of age who sustained wrist fracture and had received 1 or more conservative treatments (eg, exercise/manual therapy, lifestyle, diet, or other advice). Study selection, data extraction, and risk-of-bias assessment were conducted independently by 2 reviewers. Results of included trials were summarized in a narrative synthesis.

RESULTS

A total of 3225 titles were screened, and 21 studies satisfying all eligibility criteria were reviewed. Over one-half of the included studies (n = 12) comprised physical therapist and/or occupational therapist interventions. Rehabilitative exercise/manual therapy was generally found to improve function and reduce pain up to 1 year after wrist fracture. However, effects were small, and home exercises were found to be comparable with physical therapist-led exercise therapy. Evidence for the effects of other nonexercised therapy (including electrotherapy, whirlpool) was equivocal and limited to the short term (<3 months). Only 2 studies explored potential moderators, and they did not show evidence of moderation by age, sex, or patient attitude of the effects of rehabilitation.

CONCLUSION

Effectiveness of current rehabilitation protocols after wrist fracture is limited, and evidence for effect moderators is lacking. Currently available trials are not large enough to produce data on subgroup effects with sufficient precision. To aid clinical practice and optimize effects of rehabilitation after wrist fracture, potential moderators need to be investigated in large trials or meta-analyses using individual participant data.

IMPACT

Many patients report persistent pain and functional limitations up to 18 months following wrist fracture. Effectiveness of current rehabilitation protocols after wrist fracture is limited and may be due to insufficient targeting of specific rehabilitation to individuals who are likely to benefit most. However, evidence for effect moderators is lacking within the currently available literature. To aid clinical practice and optimize effects of rehabilitation, investigating potential moderators of rehabilitation in individuals with wrist fracture via large trials or meta-analysis of individual participant data is research and policy imperative.

Impact of virtual embodiment and exercises on functional ability and range of motion in orthopedic rehabilitation

Recent evidence supports the use of immersive virtual reality (immersive VR) as a means of applying visual feedback techniques in neurorehabilitation. In this study, we investigated the benefits of an embodiment-based immersive VR training program for orthopedic upper limb rehabilitation, with the aim of improving the motor functional ability of the arm and accelerating the rehabilitation process in patients with a conservatively managed distal radius fracture. We designed a rehabilitation program based on developing ownership over a virtual arm and then exercising it in immersive VR. We carried out a between 3-group controlled trial with 54 patients (mean age = 61.80 ± 14.18): 20 patients were assigned to the experimental training group (immersive VR), 20 to the conventional digit mobilization (CDM) training control group, and 14 to a non-immersive (non-immersive VR) training control group. We found that functional recovery of the arm in the immersive VR group was correlated with the ownership and agency scores over the virtual arm. We also found larger range of joint movements and lower disability of the fractured arm compared with patients in the Non-immersive VR and CDM groups. Feeling embodied in a virtual body can be used as a rehabilitation tool to speed up and improve motor functional recovery of a fractured arm after the immobilization period.

Ulnar Styloid Fracture Accompanying Distal Radius Fracture Does Not Affect Hand Function, but What About Hand Dexterity?

Introduction  Hand dexterity is not addressed in patients with distal radius fracture (DRF) accompanied with ulnar styloid fracture (USF) in literature. This study aimed to determine whether an associated USF following a DRF has any effect on hand dexterity. Materials and Methods  Patients diagnosed with DRF were included in the study and were divided into two groups according to the USF presence (USF group and non-USF group). Pain, range of motion, Quick-DASH (Quick-Disabilities of the Arm, Shoulder, and Hand), handgrip and pinch strength, Purdue Pegboard test, and Jebsen Taylor Hand Function test were measured in the sixth month. Results  A total of 125 patients, 68 females (54.4%) and 57 males (45.6%) were included in the study. The mean age of the patients was 47.15 ± 13.41 (18-65) years. There were 60 patients (48%) in the USF group and 65 patients (52%) in the non-USF group. No significant difference was found in pain, range of motion, Quick-DASH and handgrip and pinch strength between the groups ( p > 0.05). The hand dexterity tests showed no statistically significant difference between the groups in the sixth month ( p > 0.05). Discussion  Hand function can be determined more accurately by assessing hand dexterity. In this study, it is emphasized that concomitant USF does not lead to poorer hand dexterity.

Balance Between Mechanical Stability and Mechano-Biology of Fracture Healing Under Volar Locking Plate

The application of volar locking plate (VLP) is promising in the treatment of dorsally comminuted and displaced fracture. However, the optimal balance between the mechanical stability of VLP and the mechanobiology at the fracture site is still unclear. The purpose of this study is to develop numerical models in conjunction with experimental studies to identify the favourable mechanical microenvironment for indirect healing, by optimizing VLP configuration and post-operative loadings for different fracture geometries. The simulation results show that the mechanical behaviour of VLP is mainly governed by the axial compression. In addition, the model shows that, under relatively large gap size (i.e., 3-5 mm), the increase of FWL could enhance chondrocyte differentiation while a large BPD could compromise the mechanical stability of VLP. Importantly, bending moment produced by wrist flexion/extension and torsion moment produced from forearm rotation could potentially hinder endochondral ossification at early stage of healing. The developed model could potentially assist orthopaedic surgeons in surgical pre-planning and designing post-operation physical therapy for treatment of distal radius fractures.

Linking commonly used hand therapy outcome measures to individual areas of the International Classification of Functioning: A systematic review

STUDY DESIGN

Systematic review.

INTRODUCTION

Identifying outcome measures that correspond to the International Classification of Functioning (ICF) provides insight into selecting appropriate outcome tools in hand therapy practice.

PURPOSE OF THE STUDY

The objective of this study is to systematically review patient-reported outcome measures commonly used in hand therapy to determine the extent to which the content represents the biopsychosocial view of the ICF.

METHODS

A comprehensive literature search was conducted. Studies that met inclusion criteria were identified, and outcome measures were extracted. The meaningful concept was determined for each item on the measure and linked to the most specific ICF category. Summary linkage calculations were completed.

RESULTS

Eleven patient-reported outcomes were identified from 43 included studies. Activity and participation had the highest content coverage followed by body functions. There was linking to personal factors and not defined-disability and mental health. Environmental factors were not represented in any of the included outcome measures. The core set representation of unique codes ranged from 8.55% to 18.80% (mean: 11.97%) for the Comprehensive ICF Core Set for Hand Conditions and from 30.43% to 47.83% (mean: 31.40%) for the Brief ICF Core Set for Hand Conditions. The percent representation of the Comprehensive ICF Core Set for Hand Conditions for unique disability ranged from 21.62% to 43.24% (mean: 20.33%) and from 62.50% to 87.50% (mean: 72.22%) for the Brief ICF Core Set for Hand Conditions.

DISCUSSION

None of the included measures represent all categories of the ICF Core Sets for Hand Conditions.

CONCLUSION

Utilizing the most recent refinement rules for the linking process, this study provides comparisons of measures along with clarity of content coverage for the most commonly used tools in the practice of hand therapy.

The Relationship between Hand Therapy and Long-Term Outcomes after Distal Radius Fracture in Older Adults: Evidence from the Randomized Wrist and Radius Injury Surgical Trial

BACKGROUND

Older patients are frequently referred to hand therapy after distal radius fracture. Supervised therapy sessions place a transportation burden on patients and are costly on both the individual and systematic levels. Furthermore, there is little evidence that supervised therapy or home exercises improve long-term outcomes.

METHODS

Data were collected for the Wrist and Radius Injury Surgical Trial, a multicenter, international, pragmatic, randomized trial of distal radius fracture treatment in patients aged 60 years and older. Referral to therapy and therapy protocol were at the discretion of the treating surgeon and therapist. The authors examined outcomes between participants who underwent therapy and those who did not and assessed the duration of therapy. The authors also analyzed the effect of therapy on subgroups at risk for poor outcomes: older participants and those who had more comorbidities or lower baseline activity.

RESULTS

Eighty percent of participants underwent therapy; 70 percent participated in both supervised therapy and home exercises. Participants had a mean 9.2 supervised sessions over 14.2 weeks. There were no differences in patient-reported outcomes between participants who underwent therapy and those who did not. Participants who did not have therapy recovered more grip strength. Participants who engaged in therapy for a shorter time reported greater function, ability to work, and satisfaction. There were no relationships revealed in subgroup analyses.

CONCLUSIONS

Hand therapy after distal radius fracture may not be necessary for older patients. Encouraging participants to resume activities of daily living as soon as possible may be as effective as formal therapy.

Pilot randomized controlled trials in the orthopaedic surgery literature: a systematic review

BACKGROUND

The primary objective of this systematic review is to examine the characteristics of pilot randomized controlled trials (RCTs) in the orthopaedic surgery literature, including the proportion framed as feasibility trials and those that lead to definitive RCTs. This review aim to answer the question of whether pilot RCTs lead to definitive RCTs, whilst investigating the quality, feasibility and overall publication trends of orthopaedic pilot trials.

METHODS

Pilot RCTs in the orthopaedic literature were identified from three electronic databases (EMBASE, MEDLINE, and Pubmed) searched from database inception to January 2018. Search criteria included the evaluation of at least one orthopaedic surgical intervention, research on humans, and publication in English. Two reviewers independently screened the pool of pilot trials, and conducted a search for corresponding definitive trials. Screened pilot RCTs were assessed for feasibility outcomes related to efficiency, cost, and/or timeliness of a large-scale clinical trial involving a surgical intervention. The quality of the pilot and definitive trials were assessed using the Checklist to Evaluate a Report of a Non-Pharmacological Trial (CLEAR NPT).

RESULTS

The initial search for pilot RCTs yielded 3857 titles, of which 49 articles were relevant for this review. 73.5% (36/49) of the orthopaedic pilot RCTs were framed as feasibility trials. Of these, 5 corresponding definitive trials (10.2%) were found, of which four were published and one ongoing. Based on author responses, the lack of a definitive RCT following the pilot trial was attributed to a lack of funding, inadequacies in recruitment, and belief that the pilot RCT sufficiently answered the research question.

CONCLUSIONS

Based on this systematic review, most pilot RCTs were characterized as feasibility trials. However, the majority of published pilot RCTs did not lead to definitive trials. This discrepancy was mainly attributed to poor feasibility (e.g. poor recruitment) and lack of funding for an orthopaedic surgical definitive trial. In recent years this discrepancy may be due to researchers saving on time and cost by rolling their pilot patients into the definitive RCT rather than publish a separate pilot trial.

Duration of wrist immobilization is associated with shoulder pain in patients with after wrist immobilization: an observational study

The main goal of this study was to determinate the extent of the relationship between shoulder pain and time of wrist and thumb immobilization required after injury. One hundred twenty-three consecutive subjects presenting to the practice of different Orthopedic Specialist hospitals with a diagnosis of distal radius or scaphoid fracture that required wrist and thumb immobilization were screened for eligibility criteria. Upper extremity pain and the need for shoulder rehabilitation were assessed using the visual analogue scale (VAS) at baseline after immobilization period (T0) 1- and 3-month follow-up (1-FU/2-FU). More than 35% patients had shoulder pain (VAS>40 mm) after immobilization of the wrist. Shoulder pain intensity after immobilization and at follow-up (1 and 3 months) was strongly correlated with the duration of the immobilization. Immobilization for 3.5 weeks or longer was the strongest predictor for the need of subsequent shoulder rehabilitation. An increased the time of immobilization of the wrist is associated with an increase in shoulder pain and need for shoulder rehabilitation in patients after wrist fracture.

Prescribed exercise programs may not be effective in reducing impairments and improving activity during upper limb fracture rehabilitation: a systematic review

QUESTION

What is the effect of exercise on increasing participation and activity levels and reducing impairment in the rehabilitation of people with upper limb fractures?

DESIGN

Systematic review of controlled trials.

PARTICIPANTS

Adults following an upper limb fracture.

INTERVENTION

Any exercise therapy program, including trials where exercise was delivered to both groups provided that the groups received different amounts of exercise.

OUTCOME MEASURES

Impairments of body structure and function, activity limitations and participation restrictions.

RESULTS

Twenty-two trials were identified that evaluated 1299 participants with an upper limb fracture. There was insufficient evidence from 13 trials to support or refute the effectiveness of home exercise therapy compared with therapist-supervised exercise or therapy that included exercise following distal radius or proximal humeral fractures. There was insufficient evidence from three trials to support or refute the effectiveness of exercise therapy compared with advice/no exercise intervention following distal radius fracture. There was moderate evidence from five trials (one examining distal radius fracture, one radial head fracture, and three proximal humeral fracture) to support commencing exercise early and reducing immobilisation in improving activity during upper limb rehabilitation compared with delayed exercise and mobilisation. There was preliminary evidence from one trial that exercise to the non-injured arm during immobilisation might lead to short-term benefits on increasing grip strength and range of movement following distal radius fracture. Less than 40% of included trials reported adequate exercise program descriptions to allow replication according to the TIDieR checklist.

CONCLUSION

There is emerging evidence that current prescribed exercise regimens may not be effective in reducing impairments and improving activity following an upper limb fracture. Starting exercise early combined with a shorter immobilisation period is more effective than starting exercise after a longer immobilisation period.

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

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

Distal Radius Fracture Outcomes and Rehabilitation

Distal radius fractures account for nearly 1 of every 5 fractures in individuals aged 65 or older. Moreover, increased susceptibility to vertebral and hip fractures has been documented in patients a year after suffering a distal radius fracture. Although women are more susceptible to hip fractures, men experience a higher mortality rate in the 7 years following a distal radius fracture. Traditional approaches to distal radius fractures have included both surgical and nonsurgical treatments, with predominant complaints involving weakness, stiffness, and pain. Nonsurgical approaches include immobilization with or without reduction, whereas surgical treatments include dorsal spanning bridge plates, percutaneous pinning, external fixation, and volar plate fixation. The nature of the fracture will determine the best treatment option, and surgeons employ a multifactorial treatment approach that includes the patient’s age, nature of injury, joint involvement, and displacement among other factors. Historically, closed reduction and percutaneous pinning have been the most popular approaches. However, volar plate fixation is quickly becoming a popular option as it minimizes tendon irritation, reduces immobilization time, and decreases risk of complication. The goal of treatment is to restore mobility, reduce pain, and improve functional outcomes following rehabilitation. The aim of this review is to summarize the most common treatments and importance of early referral to hand therapy to improve functional outcomes.

Rehabilitation for distal radial fractures in adults

BACKGROUND

Fracture of the distal radius is a common clinical problem, particularly in older people with osteoporosis. There is considerable variation in the management, including rehabilitation, of these fractures. This is an update of a Cochrane review first published in 2002 and last updated in 2006.

OBJECTIVES

To examine the effects of rehabilitation interventions in adults with conservatively or surgically treated distal radial fractures.

SEARCH METHODS

We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL 2014; Issue 12), MEDLINE, EMBASE, CINAHL, AMED, PEDro, OTseeker and other databases, trial registers, conference proceedings and reference lists of articles. We did not apply any language restrictions. The date of the last search was 12 January 2015.

SELECTION CRITERIA

Randomised controlled trials (RCTs) or quasi-RCTs evaluating rehabilitation as part of the management of fractures of the distal radius sustained by adults. Rehabilitation interventions such as active and passive mobilisation exercises, and training for activities of daily living, could be used on their own or in combination, and be applied in various ways by various clinicians.

DATA COLLECTION AND ANALYSIS

The review authors independently screened and selected trials, and reviewed eligible trials. We contacted study authors for additional information. We did not pool data.

MAIN RESULTS

We included 26 trials, involving 1269 mainly female and older patients. With few exceptions, these studies did not include people with serious fracture or treatment-related complications, or older people with comorbidities and poor overall function that would have precluded trial participation or required more intensive treatment. Only four of the 23 comparisons covered by these 26 trials were evaluated by more than one trial. Participants of 15 trials were initially treated conservatively, involving plaster cast immobilisation. Initial treatment was surgery (external fixation or internal fixation) for all participants in five trials. Initial treatment was either surgery or plaster cast alone in six trials. Rehabilitation started during immobilisation in seven trials and after post-immobilisation in the other 19 trials. As well as being small, the majority of the included trials had methodological shortcomings and were at high risk of bias, usually related to lack of blinding, that could affect the validity of their findings. Based on GRADE criteria for assessment quality, we rated the evidence for each of the 23 comparisons as either low or very low quality; both ratings indicate considerable uncertainty in the findings.For interventions started during immobilisation, there was very low quality evidence of improved hand function for hand therapy compared with instructions only at four days after plaster cast removal, with some beneficial effects continuing one month later (one trial, 17 participants). There was very low quality evidence of improved hand function in the short-term, but not in the longer-term (three months), for early occupational therapy (one trial, 40 participants), and of a lack of differences in outcome between supervised and unsupervised exercises (one trial, 96 participants).Four trials separately provided very low quality evidence of clinically marginal benefits of specific interventions applied in addition to standard care (therapist-applied programme of digit mobilisation during external fixation (22 participants); pulsed electromagnetic field (PEMF) during cast immobilisation (60 participants); cyclic pneumatic soft tissue compression using an inflatable cuff placed under the plaster cast (19 participants); and cross-education involving strength training of the non-fractured hand during cast immobilisation with or without surgical repair (39 participants)).For interventions started post-immobilisation, there was very low quality evidence from one study (47 participants) of improved function for a single session of physiotherapy, primarily advice and instructions for a home exercise programme, compared with 'no intervention' after cast removal. There was low quality evidence from four heterogeneous trials (30, 33, 66 and 75 participants) of a lack of clinically important differences in outcome in patients receiving routine physiotherapy or occupational therapy in addition to instructions for home exercises versus instructions for home exercises from a therapist. There was very low quality evidence of better short-term hand function in participants given physiotherapy than in those given either instructions for home exercises by a surgeon (16 participants, one trial) or a progressive home exercise programme (20 participants, one trial). Both trials (46 and 76 participants) comparing physiotherapy or occupational therapy versus a progressive home exercise programme after volar plate fixation provided low quality evidence in favour of a structured programme of home exercises preceded by instructions or coaching. One trial (63 participants) provided very low quality evidence of a short-term, but not persisting, benefit of accelerated compared with usual rehabilitation after volar plate fixation.For trials testing single interventions applied post-immobilisation, there was very low quality evidence of no clinically significant differences in outcome in patients receiving passive mobilisation (69 participants, two trials), ice (83 participants, one trial), PEMF (83 participants, one trial), PEMF plus ice (39 participants, one trial), whirlpool immersion (24 participants, one trial), and dynamic extension splint for patients with wrist contracture (40 participants, one trial), compared with no intervention. This finding applied also to the trial (44 participants) comparing PEMF versus ice, and the trial (29 participants) comparing manual oedema mobilisation versus traditional oedema treatment. There was very low quality evidence from single trials of a short-term benefit of continuous passive motion post-external fixation (seven participants), intermittent pneumatic compression (31 participants) and ultrasound (38 participants).

AUTHORS' CONCLUSIONS

The available evidence from RCTs is insufficient to establish the relative effectiveness of the various interventions used in the rehabilitation of adults with fractures of the distal radius. Further randomised trials are warranted. However, in order to optimise research effort and engender the large multicentre randomised trials that are required to inform practice, these should be preceded by research that aims to identify priority questions.

Preventing functional loss during immobilization after osteoporotic wrist fractures in elderly patients: a randomized clinical trial

BACKGROUND

Distal radius fractures are among the most common fractures and account for approximately one-sixth of all fractures diagnosed. Therapy results after distal radius fracture, especially of elderly patients, are often suboptimal. The inevitable immobilization for several weeks leads to reduction in range of motion, deterioration of muscle strength, malfunction of fine motor skills as well as changes of motor and sensory representations in the brain. Currently, there are no strategies to counteract these immobilization problems. The overall aim of the study is to investigate the therapeutic potential of motor-cognitive approaches (mental practice or mirror therapy) on hand function after wrist fracture.

METHODS/DESIGN

This study is a controlled, randomized, longitudinal intervention study with three intervention groups. One experimental group imagines movements of the fractured upper extremity without executing them (mental practice). The second experimental group receives a mirror therapy program consisting of the performance of functional movement synergies using the unaffected forearm, wrist, and hand. The control group completes a relaxation training regime. Additionally, all patients receive usual care by the general practitioner. We include women aged 60 years and older having a distal radius fracture and sufficient cognitive function. All groups are visited at home for therapy sessions 5 times per week for the first 3 weeks and 3 times per week for weeks 4 to 6. Measurements are taken at therapy onset, and after 3, 6 and 12 weeks. The primary outcome measure will assess upper extremity functioning (Patient-Rated Wrist Evaluation [PRWE]), while secondary outcome measures cover subjective wrist function (Disabilities of the Arm and Shoulder; [DASH], objective impairment (range of motion, grip force) and quality of life (EuroQol-5D, [EQ5D]).

DISCUSSION

Results from this trial will contribute to the evidence on motor-cognitive approaches in the early therapy of distal radius fractures.

TRIAL REGISTRATION

The trial is registered at ClinicalTrials.gov with registration number NCT01394809 and was granted permission by the Medical Ethical Review Committee of the University of Tübingen in June 2011.
