The impact of the frequency, duration and type of physiotherapy on discharge after hip fracture surgery: a secondary analysis of UK national linked audit data.

Additional physiotherapy in the first postoperative week was associated with fewer days to discharge after hip fracture surgery. A 7-day physiotherapy service in the first postoperative week should be considered as a new key performance indicator in evaluating the quality of care for patients admitted with a hip fracture. INTRODUCTION: To examine the association between physiotherapy in the first week after hip fracture surgery and discharge from acute hospital. METHODS: We linked data from the UK Physiotherapy Hip Fracture Sprint Audit to hospital records for 5395 patients with hip fracture in May and June 2017. We estimated the association between the number of days patients received physiotherapy in the first postoperative week; its overall duration (< 2 h, ≥ 2 h; 30-min increment) and type (mobilisation alone, mobilisation and exercise) and the cumulative probability of discharge from acute hospital over 30 days, using proportional odds regression adjusted for confounders and the competing risk of death. RESULTS: The crude and adjusted odds ratios of discharge were 1.24 (95% CI 1.19-1.30) and 1.26 (95% CI 1.19-1.33) for an additional day of physiotherapy, 1.34 (95% CI 1.18-1.52) and 1.33 (95% CI 1.12-1.57) for ≥ 2 versus < 2 h physiotherapy, and 1.11 (95% CI 1.08-1.15) and 1.10 (95% CI 1.05-1.15) for an additional 30-min of physiotherapy. Physiotherapy type was not associated with discharge. CONCLUSION: We report an association between physiotherapy and discharge after hip fracture. An average UK hospital admitting 375 patients annually may save 456 bed-days if current provision increased so all patients with hip fracture received physiotherapy on 6-7 days in the first postoperative week. A 7-day physiotherapy service totalling at least 2 h in the first postoperative week may be considered a key performance indicator of acute care quality after hip fracture.

Effect of inpatient rehabilitation treatment ingredients on functioning, quality of life, length of stay, discharge destination, and mortality among older adults with unplanned admission: an overview review.

BACKGROUND: To synthesise the evidence for the effectiveness of inpatient rehabilitation treatment ingredients (versus any comparison) on functioning, quality of life, length of stay, discharge destination, and mortality among older adults with an unplanned hospital admission. METHODS: A systematic search of Cochrane Library, MEDLINE, Embase, PsychInfo, PEDro, BASE, and OpenGrey for published and unpublished systematic reviews of inpatient rehabilitation interventions for older adults following an unplanned admission to hospital from database inception to December 2020. Duplicate screening for eligibility, quality assessment, and data extraction including extraction of treatment components and their respective ingredients employing the Treatment Theory framework. Random effects meta-analyses were completed overall and by treatment ingredient. Statistical heterogeneity was assessed with the inconsistency-value (I2). RESULTS: Systematic reviews (n = 12) of moderate to low quality, including 44 non-overlapping relevant RCTs were included. When incorporated in a rehabilitation intervention, there was a large effect of endurance exercise, early intervention and shaping knowledge on walking endurance after the inpatient stay versus comparison. Early intervention, repeated practice activities, goals and planning, increased medical care and/or discharge planning increased the likelihood of discharge home versus comparison. The evidence for activities of daily living (ADL) was conflicting. Rehabilitation interventions were not effective for functional mobility, strength, or quality of life, or reduce length of stay or mortality. Therefore, we did not explore the potential role of treatment ingredients for these outcomes. CONCLUSION: Benefits observed were often for subgroups of the older adult population e.g., endurance exercise was effective for endurance in older adults with chronic obstructive pulmonary disease, and early intervention was effective for endurance for those with hip fracture. Future research should determine whether the effectiveness of these treatment ingredients observed in subgroups, are generalisable to older adults more broadly. There is a need for more transparent reporting of intervention components and ingredients according to established frameworks to enable future synthesis and/or replication.

Prognostic factors of depression and depressive symptoms after hip fracture surgery: systematic review.

BACKGROUND: Patients with hip fracture and depression are less likely to recover functional ability. This review sought to identify prognostic factors of depression or depressive symptoms up to 1 year after hip fracture surgery in adults. This review also sought to describe proposed underlying mechanisms for their association with depression or depressive symptoms. METHODS: We searched for published (MEDLINE, Embase, PsychInfo, CINAHL and Web of Science Core Collection) and unpublished (OpenGrey, Greynet, BASE, conference proceedings) studies. We did not impose any date, geographical, or language limitations. Screening (Covidence), extraction (Checklist for critical Appraisal and data extraction for systematic Reviews of prediction Modelling Studies, adapted for use with prognostic factors studies Checklist), and quality appraisal (Quality in Prognosis Studies tool) were completed in duplicate. Results were summarised narratively. RESULTS: In total, 37 prognostic factors were identified from 12 studies included in this review. The quality of the underlying evidence was poor, with all studies at high risk of bias in at least one domain. Most factors did not have a proposed mechanism for the association. Where factors were investigated by more than one study, the evidence was often conflicting. CONCLUSION: Due to conflicting and low quality of available evidence it is not possible to make clinical recommendations based on factors prognostic of depression or depressive symptoms after hip fracture. Further high-quality research investigating prognostic factors is warranted to inform future intervention and/or stratified approaches to care after hip fracture.

Inequity in rehabilitation interventions after hip fracture: a systematic review.

OBJECTIVE: to determine the extent to which equity factors contributed to eligibility criteria of trials of rehabilitation interventions after hip fracture. We define equity factors as those that stratify healthcare opportunities and outcomes. DESIGN: systematic search of MEDLINE, Embase, CINHAL, PEDro, Open Grey, BASE and ClinicalTrials.gov for randomised controlled trials of rehabilitation interventions after hip fracture published between 1 January 2008 and 30 May 2018. Trials not published in English, secondary prevention or new models of service delivery (e.g. orthogeriatric care pathway) were excluded. Duplicate screening for eligibility, risk of bias (Cochrane Risk of Bias Tool) and data extraction (Cochrane's PROGRESS-Plus framework). RESULTS: twenty-three published, eight protocol, four registered ongoing randomised controlled trials (4,449 participants) were identified. A total of 69 equity factors contributed to eligibility criteria of the 35 trials. For more than 50% of trials, potential participants were excluded based on residency in a nursing home, cognitive impairment, mobility/functional impairment, minimum age and/or non-surgical candidacy. Where reported, this equated to the exclusion of 2,383 out of 8,736 (27.3%) potential participants based on equity factors. Residency in a nursing home and cognitive impairment were the main drivers of these exclusions. CONCLUSION: the generalisability of trial results to the underlying population of frail older adults is limited. Yet, this is the evidence base underpinning current service design. Future trials should include participants with cognitive impairment and those admitted from nursing homes. For those excluded, an evidence-informed reasoning for the exclusion should be explicitly stated. PROSPERO: CRD42018085930.

Prognostic factors of functional outcome after hip fracture surgery: a systematic review.

Objective: this systematic review aimed to identify immutable and modifiable prognostic factors of functional outcomes and their proposed mechanism after hip fracture surgery. Design: systematic search of MEDLINE, Embase, CINAHL, PEDRO, OpenGrey and ClinicalTrials.gov for observational studies of prognostic factors of functional outcome after hip fracture among surgically treated adults with mean age of 65 years and older. Study selection, quality assessment, and data extraction were completed independently by two reviewers. The Quality in Prognosis Studies Tool was used for quality assessment and assigning a level of evidence to factors. Proposed mechanisms for reported associations were extracted from discussion sections. Results: from 33 studies of 9,552 patients, we identified 25 prognostic factors of functional outcome after hip fracture surgery. We organised factors into groups: demographics, injury and comorbidities, body composition, complications, and acute care. We assigned two factors a weak evidence level-anaemia and cognition. We assigned Parkinson's disease an inconclusive evidence level. We could not assign an evidence level to the remaining 22 factors due to the high risk of bias across studies. Frailty was the proposed mechanism for the association between anaemia and functional outcome. Medication management, perceived potential, complications and time to mobility were proposed as mechanisms for the association between cognition and functional outcome. Conclusion: we identified one modifiable and one immutable prognostic factor for functional outcomes after hip fracture surgery. Future research may target patients with anaemia or cognitive impairment by intervening on the prognostic factor or the underlying mechanisms.

A pilot randomized controlled trial comparing effectiveness of prism glasses, visual search training and standard care in hemianopia.

OBJECTIVE: Pilot trial to compare prism therapy and visual search training, for homonymous hemianopia, to standard care (information only). METHODS: Prospective, multicentre, parallel, single-blind, three-arm RCT across fifteen UK acute stroke units. PARTICIPANTS: Stroke survivors with homonymous hemianopia. INTERVENTIONS: Arm a (Fresnel prisms) for minimum 2 hours, 5 days per week over 6 weeks. Arm b (visual search training) for minimum 30 minutes, 5 days per week over 6 weeks. Arm c (standard care-information only). INCLUSION CRITERIA: Adult stroke survivors (>18 years), stable hemianopia, visual acuity better than 0.5 logMAR, refractive error within ±5 dioptres, ability to read/understand English and provide consent. OUTCOMES: Primary outcomes were change in visual field area from baseline to 26 weeks and calculation of sample size for a definitive trial. Secondary measures included Rivermead Mobility Index, Visual Function Questionnaire 25/10, Nottingham Extended Activities of Daily Living, Euro Qual, Short Form-12 questionnaires and Radner reading ability. Measures were post-randomization at baseline and 6, 12 and 26 weeks. RANDOMIZATION: Randomization block lists stratified by site and partial/complete hemianopia. BLINDING: Allocations disclosed to patients. Primary outcome assessor blind to treatment allocation. RESULTS: Eighty-seven patients were recruited: 27-Fresnel prisms, 30-visual search training and 30-standard care; 69% male; mean age 69 years (SD 12). At 26 weeks, full results for 24, 24 and 22 patients, respectively, were compared to baseline. Sample size calculation for a definitive trial determined as 269 participants per arm for a 200 degree2 visual field area change at 90% power. Non-significant relative change in area of visual field was 5%, 8% and 3.5%, respectively, for the three groups. Visual Function Questionnaire responses improved significantly from baseline to 26 weeks with visual search training (60 [SD 19] to 68.4 [SD 20]) compared to Fresnel prisms (68.5 [SD 16.4] to 68.2 [18.4]: 7% difference) and standard care (63.7 [SD 19.4] to 59.8 [SD 22.7]: 10% difference), P=.05. Related adverse events were common with Fresnel prisms (69.2%; typically headaches). CONCLUSIONS: No significant change occurred for area of visual field area across arms over follow-up. Visual search training had significant improvement in vision-related quality of life. Prism therapy produced adverse events in 69%. Visual search training results warrant further investigation.

Home-based Reach-to-Grasp training for people after stroke is feasible: a pilot randomised controlled trial.

OBJECTIVE: To determine feasibility of a randomised controlled trial (RCT) of home-based Reach-to-Grasp training after stroke. DESIGN: single-blind parallel group RCT. PARTICIPANTS: Residual arm deficit less than 12 months post-stroke. INTERVENTIONS: Reach-to-Grasp training in 14 one-hour therapist's visits over 6 weeks, plus one hour self-practice per day (total 56 hours). CONTROL: Usual care. MAIN MEASURES: Action Research Arm Test (ARAT), Wolf Motor Function Test (WMFT), pre-randomisation, 7, 12, 24 weeks post-randomisation. RESULTS: Forty-seven participants (Reach-to-Grasp=24, usual care=23) were randomised over 17 months. Reach-to-Grasp participants received a median (IQR) 14 (13,14) visits, and performed 157 (96,211) repetitions per visit; plus 30 minutes (22,45) self-practice per day. Usual care participants received 10.5 (5,14) therapist visits, comprising 38.6 (30,45) minutes of arm therapy with 16 (6,24) repetitions of functional tasks per visit. Median ARAT scores in the reach-to-grasp group were 8.5 (3.0,24.0) at baseline and 14.5 (3.5,26.0) at 24 weeks compared to median of 4 at both time points (IQR: baseline (3.0,14.0), 24 weeks (3.0,30.0)) in the usual-care group. Median WMFT tasks completed at baseline and 24 weeks were 6 (3.0,11.5) and 8.5 (4.5,13.5) respectively in the reach-to-grasp group and 4 (3.0,10.0), 6 (3.0,14.0) in the usual care group. Incidence of arm pain was similar between groups. The study was stopped before 11 patients reached the 24 weeks assessment. CONCLUSIONS: An RCT of home-based Reach-to-Grasp training after stroke is feasible and safe. With ARAT being our preferred measure it is estimated that 240 participants will be needed for a future two armed trial.

UK survey of occupational therapist's and physiotherapist's experiences and attitudes towards hip replacement precautions and equipment.

BACKGROUND: Total hip replacement (THR) is one of the most common orthopaedic procedures in the United Kingdom (UK). Historically, people following THR have been provided with hip precautions and equipment such as: raised toilet seats and furniture rises, in order to reduce the risks of dislocation post-operation. The purpose of this study was to determine current practices in the provision of these interventions in the UK for people following primary THR. METHODS: A 27-question, self-administered online survey was developed and distributed to UK physiotherapists and occupational therapists involved in the management of people following primary THR (target respondents). The survey included questions regarding the current practices in the provision of equipment and hip precautions for THR patients, and physiotherapist's and occupational therapist's attitudes towards these practices. The survey was disseminated through print and web-based/social media channels. RESULTS: 170 health professionals (87 physiotherapists and 83 occupational therapists), responded to the survey. Commonly prescribed equipment in respondent's health trusts were raised toilet seats (95 %), toilet frames and rails (88 %), furniture raises (79 %), helping hands/grabbers (77 %), perching stools (75 %) and long-handled shoe horns (75 %). Hip precautions were routinely prescribed by 97 % of respondents. Hip precautions were most frequently taught in a pre-operative group (52 % of respondents). Similarly equipment was most frequently provided pre-operatively (61 % respondents), and most commonly by occupational therapists (74 % respondents). There was variability in the advice provided on the duration of hip precautions and equipment from up to 6 weeks post-operatively to life-time usage. CONCLUSIONS: Current practice on hip precautions and provision of equipment is not full representative of clinician's perceptions of best care after THR. Future research is warranted to determine whether and to whom hip precautions and equipment should be prescribed post-THR as opposed to the current 'blanket' provision of equipment and movement restriction provided in UK practice.

Fatigue, psychological and cognitive impairment following transient ischaemic attack and minor stroke: a systematic review.

Transient ischaemic attack (TIA) and minor stroke are characterized by short-lasting symptoms; however, anecdotal and empirical evidence suggests that these patients experience ongoing cognitive/psychological impairment for which they are not routinely treated. The aims were (i) to investigate the prevalence and time course of fatigue, anxiety, depression, post-traumatic stress disorder(PTSD) and cognitive impairment following TIA/minor stroke; (ii) to explore the impact on quality of life (QoL), change in emotions and return to work; and (iii) to identify where further research is required and potentially inform an intervention study. A systematic review of MEDLINE, EMBASE, PSYCINFO, CINAHL, the Cochrane libraries and the grey literature between January 1993 and April 2013 was undertaken. Literature was screened and data were extracted by two independent reviewers. Studies were included of adult TIA/minor stroke participants with any of the outcomes of interest: fatigue, anxiety, depression, PTSD, cognitive impairment, QoL, change in emotions and return to work. Random-effects meta-analysis pooled outcomes by measurement tool. Searches identified 5976 records, 289 were assessed for eligibility and 31 studies were included. Results suggest high levels of cognitive impairment and depression post-TIA/minor stroke which decreased over time. However, frequencies varied between studies. Limited information was available on anxiety, PTSD and fatigue. Meta-analysis revealed that the measurement tool administered influenced the prevalence of cognitive impairment: Mini-Mental State Examination 17% [95% confidence interval (CI) 7, 26]; neuropsychological test battery 39% (95% CI 28, 50); Montreal Cognitive Assessment 54% (95% CI 43, 66). There is evidence to suggest that TIA/minor stroke patients may experience residual impairments; however, results should be interpreted with caution because of the few high quality studies. Notwithstanding, it is important to raise awareness of potential subtle but meaningful residual impairments.

Blind outcome assessment: the development and use of procedures to maintain and describe blinding in a pragmatic physiotherapy rehabilitation trial.

OBJECTIVES: (1) To develop trial protocols which promote the achievement of blind outcome assessment. (2) To report outcome assessor beliefs regarding group allocation at follow-up assessments. (3) To document and describe instances of unblinding occurring during the trial to assist and inform rehabilitation researchers and clinicians. DESIGN: Prospective longitudinal observational study. SETTING: An NHS Hospital Trust specializing in orthopaedic surgery. SUBJECTS: One hundred and seven patients participating in a prospective pragmatic randomized controlled trial investigating physiotherapy rehabilitation following total knee arthroplasty, plus three outcome assessors. INTERVENTIONS: A protocol was developed using available research and designed to minimize instances of unblinding during a physiotherapy rehabilitation trial. Administrative, office, patient and research staff procedures were included. MAIN MEASURES: Trial questionnaires measured blind outcome assessment responses at 3 and 12 months post surgery. The outcome assessor kept a field diary recording the events surrounding instances of unblinding. Data underwent descriptive and content analysis. RESULTS: Blind outcome assessment was believed successful for n = 74 (81.32%) assessments at 3-month follow-up, and n = 83 (91.21%) at 12 months. Forty instances (n = 28 participants) of unblinding were described in the field diary. While the main cause of unblinding was participants telling the outcome assessor, in 12.5% of events the assessor drew the wrong conclusion regarding group allocation. Not all unblinding events were remembered at subsequent assessments, even in this relatively small trial. CONCLUSIONS: Blind outcome assessment was considered achievable in this trial. Specific trial protocols enabled blinding beliefs to be reported and instances of unblinding to be described.

A multicentre, randomised controlled trial to compare the clinical and cost-effectiveness of Lee Silverman Voice Treatment versus standard NHS Speech and Language Therapy versus control in Parkinson's disease: a study protocol for a randomised controlled trial.

BACKGROUND: Parkinson's disease (PD) affects approximately 145,519 people in the UK. Speech impairments are common with a reported prevalence of 68%, which increase physical and mental demands during conversation, reliance on family and/or carers, and the likelihood of social withdrawal reducing quality of life. In the UK, two approaches to Speech and Language Therapy (SLT) intervention are commonly available: National Health Service (NHS) SLT or Lee Silverman Voice Treatment (LSVT LOUD®). NHS SLT is tailored to the individuals' needs per local practice typically consisting of six to eight weekly sessions; LSVT LOUD® comprises 16 sessions of individual treatment with home-based practice over 4 weeks. The evidence-base for their effectiveness is inconclusive. METHODS/DESIGN: PD COMM is a phase III, multicentre, three-arm, unblinded, randomised controlled trial. Five hundred and forty-six people with idiopathic PD, reporting speech or voice problems will be enrolled. We will exclude those with a diagnosis of dementia, laryngeal pathology or those who have received SLT for speech problems in the previous 2 years. Following informed consent and completion of baseline assessments, participants will be randomised in a 1:1:1 ratio to no-intervention control, NHS SLT or LSVT LOUD® via a central computer-generated programme, using a minimisation procedure with a random element, to ensure allocation concealment. Participants randomised to the intervention groups will start treatment within 4 (NHS SLT) or 7 (LSVT LOUD®) weeks of randomisation. PRIMARY OUTCOME: Voice Handicap Index (VHI) total score at 3 months. Secondary outcomes include: VHI subscales, Parkinson's Disease Questionnaire-39; Questionnaire on Acquired Speech Disorders; EuroQol-5D-5 L; ICECAP-O; resource utilisation; adverse events and carer quality of life. Mixed-methods process and health economic evaluations will take place alongside the trial. Assessments will be completed before randomisation and at 3, 6 and 12 months after randomisation. The trial started in December 2015 and will run for 77 months. Recruitment will take place in approximately 42 sites around the UK. DISCUSSION: The trial will test the hypothesis that SLT is effective for the treatment of speech or voice problems in people with PD compared to no SLT. It will further test whether NHS SLT or LSVT LOUD® provide greater benefit and determine the cost-effectiveness of both interventions. TRIAL REGISTRATION: International Standard Randomised Controlled Trials Number (ISRCTN) Registry, ID: 12421382. Registered on 18 April 2016.

Pilot randomised controlled trial of occupational therapy to optimise independence in Parkinson's disease: the PD OT trial.

OBJECTIVE: To perform a pilot trial of occupational therapy (OT) to optimise functional independence in Parkinson disease (PD) to assess accrual/withdrawal rates, acceptability, outcome measures, and inform sample-size calculation. METHOD: Non-demented patients with idiopathic PD and difficulties with activities of daily living (ADL) were recruited provided they had not received OT in the last 2 years and/or physiotherapy in the last year. Patients were randomised to immediate OT or OT after completion of the trial. Patients randomised to OT were assessed at home by an experienced therapist and then received six home treatment sessions over 2 months. Interventions were targeted at functional independence and mobility goals. Outcome measures were: Nottingham Extended Activity of Daily Living Scale, Rivermead Mobility Index, Unified Parkinson's Disease Rating Scale ADL scale, Parkinson's Disease Questionnaire 39, EuroQol-EQ-5D, Hospital Anxiety and Depression Scale, and health economics analysis. RESULTS: 39 patients (25 male; mean age 73 years) were recruited from four centres over 16 months. The mean difference in NEADL at 8 months was 3.5 (95% CI -3.2 to 10.2). The mean difference in PDQ-39 Summary Score was 3.8 (95% CI -4.94 to 12.6). There were strong correlations between the PDQ-39 and other outcomes. The intervention was acceptable to patients, with a low withdrawal rate and good questionnaire completion. CONCLUSION: Randomisation to a trial of OT in PD is feasible. NEADL and PDQ-39 are relevant outcomes and provided data to inform sample size for an adequately powered randomised trial for which there is pressing need.

Does physical activity change following hip and knee replacement? Matched case-control study evaluating Physical Activity Scale for the Elderly data from the Osteoarthritis Initiative.

OBJECTIVES: To determine whether physical activity measured using the Physical Activity Scale for the Elderly (PASE), changes during the initial 24 months post-total hip (THR) or knee replacement (TKR), and how this compares to a matched non-arthroplasty cohort. DESIGN: Case-controlled study analysis of a prospectively collected dataset. SETTING: USA community-based. PARTICIPANTS: 116 people post-THR, 105 people post-TKR compared to 663 people who had not undergone THR or TKR, or had hip or knee osteoarthritis. Cohorts were age-, gender- and BMI-matched. MAIN OUTCOME MEASURES: Physical activity assessed using the 12-item PASE at 12 and 24 months post operatively. RESULTS: There was no significant difference in total PASE score between pre-operative to 12 months (mean: 136 vs 135 points; p=0.860) or 24 months following THR (mean: 136 vs 132 points; p=0.950). Whilst there was no significant difference in total PASE score from pre-operative to 12 months post-TKR (126 vs 121 points; p=0.930), by 24 months people following TKR reported significantly greater physical activity (126 vs 142 points; p=0.040). There was no statistically significant difference in physical activity between the normative matched and THR (p≥0.140) or TKR (p≥0.060) cohorts at 12 or 24 months post joint replacement. CONCLUSIONS: Physical activity is not appreciably different to pre-operative levels at 12 or 24 months post-THR, but was greater at 24 months following TKR. Health promotion strategies are needed to encourage greater physical activity participation following joint replacement, and particularly targeting those who undergo THR.

Rehabilitation interventions for foot drop in neuromuscular disease.

BACKGROUND: "Foot drop" or "Floppy foot drop" is the term commonly used to describe weakness or contracture of the muscles around the ankle joint. It may arise from many neuromuscular diseases. OBJECTIVES: To conduct a systematic review of randomised trials of treatment for footdrop resulting from neuromuscular disease. SEARCH STRATEGY: We searched the Cochrane Neuromuscular Disease Group Trials Register (July 2005), MEDLINE (January 1966 to July 2005), EMBASE (January 1980 to July 2005), AMED (January 1985 to July 2005) and CINAHL databases (January 1982 to July 2005). SELECTION CRITERIA: Randomised and quasi-randomised trials of physical, orthotic and surgical treatments for footdrop resulting from lower motor neuron or muscle disease and related contractures were included. People with primary joint disease were excluded. Interventions included a 'wait and see' approach, physiotherapy, orthotics, surgery and pharmacological therapy. The primary outcome measure was ability to walk whilst secondary outcome measures included dorsiflexor torque and strength, measures of 'activity' and 'participation' and adverse effects. DATA COLLECTION AND ANALYSIS: Methodological quality was evaluated by two authors using the van Tulder criteria. Three studies with altogether 139 participants were included in the review. Heterogeneity of the studies precluded pooling the data. MAIN RESULTS: Early surgery did not significantly affect walking speed in a trial including 20 children with Duchenne muscular dystrophy. After one year, the mean difference (MD) of the 28 feet walking time was 0.00 seconds (95% confidence interval (CI) -0.83 to 0.83) and the MD of the 150 feet walking time was -2.88 seconds, (95% CI -8.18 to 2.42). In a trial with altogether 26 participants with Charcot-Marie-Tooth disease (hereditary motor and sensory neuropathy), long-term strength training significantly increased walking speed on a 6 metre timed walk (MD -0.70 seconds, 95% CI -1.17 to -0.23) but not on a 50 metre timed walk (MD -1.9 seconds, 95% CI -4.09 to 0.29). In a trial of a 24-week strength training programme in 28 participants with myotonic dystrophy, there was no significant change in walking speed on either a 6 or 50 metre walk. AUTHORS' CONCLUSIONS: Using the primary outcome of ability to walk, only one study demonstrated a positive effect and that was an exercise programme for people with Charcot-Marie-Tooth disease. Surgery was not significantly effective in children with Duchenne Muscular Dystrophy. More evidence generated by methodologically sound trials is required.

Change in stroke incidence, mortality, case-fatality, severity, and risk factors in Oxfordshire, UK from 1981 to 2004 (Oxford Vascular Study).

BACKGROUND: The incidence of stroke is predicted to rise because of the rapidly ageing population. However, over the past two decades, findings of randomised trials have identified several interventions that are effective in prevention of stroke. Reliable data on time-trends in stroke incidence, major risk factors, and use of preventive treatments in an ageing population are required to ascertain whether implementation of preventive strategies can offset the predicted rise in stroke incidence. We aimed to obtain these data. METHODS: We ascertained changes in incidence of transient ischaemic attack and stroke, risk factors, and premorbid use of preventive treatments from 1981-84 (Oxford Community Stroke Project; OCSP) to 2002-04 (Oxford Vascular Study; OXVASC). FINDINGS: Of 476 patients with transient ischaemic attacks or strokes in OXVASC, 262 strokes and 93 transient ischaemic attacks were incident events. Despite more complete case-ascertainment than in OCSP, age-adjusted and sex-adjusted incidence of first-ever stroke fell by 29% (relative incidence 0.71, 95% CI 0.61-0.83, p=0.0002). Incidence declined by more than 50% for primary intracerebral haemorrhage (0.47, 0.27-0.83, p=0.01) but was unchanged for subarachnoid haemorrhage (0.83, 0.44-1.57, p=0.57). Thus, although 28% more incident strokes (366 vs 286) were expected in OXVASC due to demographic change alone (33% increase in those aged 75 or older), the observed number fell (262 vs 286). Major reductions were recorded in mortality rates for incident stroke (0.63, 0.44-0.90, p=0.02) and in incidence of disabling or fatal stroke (0.60, 0.50-0.73, p<0.0001), but no change was seen in case-fatality due to incident stroke (17.2% vs 17.8%; age and sex adjusted relative risk 0.85, 95% CI 0.57-1.28, p=0.45). Comparison of premorbid risk factors revealed substantial reductions in the proportion of smokers, mean total cholesterol, and mean systolic and diastolic blood pressures and major increases in premorbid treatment with antiplatelet, lipid-lowering, and blood pressure lowering drugs (all p<0.0001). INTERPRETATION: The age-specific incidence of major stroke in Oxfordshire has fallen by 40% over the past 20 years in association with increased use of preventive treatments and major reductions in premorbid risk factors.

Single blind randomized controlled trial of visual feedback after stroke: effects on stance symmetry and function.

A number of before and after and single case design studies of visual feedback have shown improvements in stance symmetry after stroke, an associated improvement in function has been demonstrated. This study examines this promising technique further using a single-blind controlled trial. Twenty-six patients were recruited from a register of consecutive admissions and randomized into treatment and control groups. Both groups received additional therapy, only the treatment group received visual feedback. Assessments were carried out independently. Significant improvements were seen in the treatment group in measures of stance symmetry and sway and motor and ADL function. Between group differences had disappeared at three months. The results indicate that feedback training incorporated into functional physiotherapy treatment can improve stance symmetry and sway. Transfer of training was indicated by improvements in ADL and gross motor function. Three months later the improvement was maintained, but did not automatically continue without treatment.

The scope for rehabilitation in severely disabled stroke patients.

PURPOSE: To argue the case that patients who are severely disabled by stroke may benefit from rehabilitation. To identify critical areas where more research may be helpful. METHOD: Discussion of four negative views which could be cited as drawbacks to rehabilitation in this group. These are: (1) that patients with severe stroke do not recover; (2) that they are too ill to receive rehabilitation; (3) that rehabilitation is ineffective even when possible; and (4) that even if rehabilitation is effective, it is not cost-effective. RESULTS: There is little work in this area. There are problems with measurement of disability in this group. None of the four negative views are supported by current evidence, and what little evidence there is provides grounds for optimism that further work could be worthwhile. CONCLUSIONS: Specific recommendations for further work include: (1) the development of better measurement scales; (2) to determine the cost of care of severely disabled stroke patients; (3) to gain a better appreciation of the value of changes in disability states; and (4) to perform an overview analysis of rehabilitation interventions examining the degree to which severity of disability affects the response to treatment.

Attentional focus of feedback for improving performance of reach-to-grasp after stroke: a randomised crossover study.

OBJECTIVE: To investigate whether feedback inducing an external focus (EF) of attention (about movement effects) was more effective for retraining reach-to-grasp after stroke compared with feedback inducing an internal focus (IF) of attention (about body movement). It was predicted that inducing an EF of attention would be more beneficial to motor performance. DESIGN: Crossover trial where participants were assigned at random to two feedback order groups: IF followed by EF or EF followed by IF. SETTING: Research laboratory. PARTICIPANTS: Forty-two people with upper limb impairment after stroke. INTERVENTION: Participants performed three reaching tasks: (A) reaching to grasp a jar; (B) placing a jar forwards on to a table; and (C) placing a jar on to a shelf. Ninety-six reaches were performed in total over one training session. MAIN OUTCOME MEASURES: Kinematic measures were collected using motion analysis. Primary outcome measures were movement duration, peak velocity of the wrist, size of peak aperture and peak elbow extension. RESULTS: Feedback inducing an EF of attention produced shorter movement durations {first feedback order group: IF mean 2.53 seconds [standard deviation (SD) 1.85]; EF mean 2.12 seconds (SD 1.63), mean difference 0.41 seconds; 95% confidence interval -0.68 to 1.5; P=0.008}, an increased percentage time to peak deceleration (P=0.01) when performing Task B, and an increased percentage time to peak velocity (P=0.039) when performing Task A compared with feedback inducing an IF of attention. However, an order effect was present whereby performance was improved if an EF of attention was preceded by an IF of attention. CONCLUSIONS: Feedback inducing an EF of attention may be of some benefit for improving motor performance of reaching in people with stroke in the short term; however, these results should be interpreted with caution. Further research using a randomised design is recommended to enable effects on motor learning to be assessed.
