Methodological difificulties in rehabilitation research

This paper presents an overview of some of the pitfalls and suggests ways of improving the quality of research into rehabilitation after stroke. The aims of rehabilitation are outlined and methodological problems inherent in this area discussed, including spontaneous recovery, multidimensional outcomes, definition of treatment and placebo effects. Major weaknesses found in the rehabilitation literature are identified and recommendations for improvement made, including the need for comparable controls, adequate numbers, appropriate outcome measures, clear definition of therapy, generalizability, and a concern for the cost-effectiveness of stroke rehabilitation packages. The field of rehabilitation is still relatively new and idiosyncratic in form and content. Thus it still provides opportunities for research into its relative effectiveness before current practices in rehabilitation become entrenched in medical practice and folklore. Adequate funding support for improved, multicentre clinical trials in rehabilitation is essential.

The Bradford community stroke trial: eight week results

To evaluate two commonly practised methods of stroke aftercare we have conducted a randomized comparison trial of day hospital (DH) and home physiotherapy (HPT). Patients over 60 years discharged from hospital following a new stroke event were eligible. One hundred and twenty-four patients were recruited, stratified by disability measured on the Barthel Index and by length of time since stroke onset, then randomized to attend a DH twice weekly or to receive HPT. Outcome measurements included the Barthel Index, Motor Club Assessment, Frenchay Activities Index, Nottingham Health Profile and the General Health Questionnaire.

One hundred and seven patients completed an eight week course of treatment. Both the DH and the HPT treated patients showed a significant but small further improvement in functional abilities with the HPT patients being significantly more able on stairs. Social function of both groups was poor but the HPT treated patients were significantly less so. More than a third of patients in each treatment group were depressed and more than a quarter of the carers were 'stressed'. The HPT patients received significantly less physiotherapy and virtually no occupational therapy compared to the DH group.

The findings suggest that HPT is slightly more effective for stroke aftercare than DH attendance and is considerably more resource efficient.

Hemiplegic shoulder pain (HSP): natural history and investigation of associated features

The prevalence of hemiplegic shoulder pain (HSP) and associated factors was studied in patients with a stroke followed for 6 months after discharge from hospital. A questionnaire was used to evaluate shoulder symptoms and an examination of the shoulder and arm was carried out three times over 6 months. A total of 108 patients were studied with a mean age of 71 years. Sixty-nine patients (63.8%) developed HSP at some time during the study period. The number with HSP was 39 at discharge from hospital, 59 at 8 weeks post-discharge and 36 at 6 months. Nine carers reported lifting the patient by pulling on the hemiplegic arm, even though six of them had received advice about correct lifting techniques. Reduced shoulder shrug was associated with HSP at all times and reduced pinch grip was also associated with HSP at discharge from hospital. Patients who required help with transfers were more likely to suffer with HSP. There was no difference in the prevalence of HSP in patients treated at the day hospital compared to those who received domiciliary physiotherapy. It is concluded that HSP is common after a stroke and the prevalence increases in the first weeks after discharge from hospital. Stroke patients and their carers need advice about correct handling of the hemiplegic arm, and more work is required to ensure that correct handling occurs after discharge in patients at high risk of this unpleasant complication.

The Bradford community stroke trial: results at six months

OBJECTIVE

Comparison of day hospital attendance and home physiotherapy for stroke patients leaving hospital to determine which service produces greater functional and social improvement for the patient, reduces emotional stress for the care giver, and lessens the need for community support.

DESIGN

Stratified, randomised trial of stroke patients attending day hospital two days a week or receiving home treatment from a community physiotherapist. The six month assessment results are reported in this paper.

SUBJECTS

Patients over 60 years old resident within the Bradford metropolitan district discharged home after a new stroke with residual disability.

SETTING

Four day hospitals in two health authorities and domiciliary work undertaken by experienced community physiotherapists.

MAIN OUTCOME MEASURES

Barthel index, functional ambulatory categories, Motor Club assessment, Frenchay activities index, and Nottingham health profile were used. Carers' stress was indicated by the general health questionnaire. Treatment given and community care provided were recorded.

RESULTS

Of 124 patients recruited, 108 were available for reassessment at six months. Both treatment groups had significantly improved in functional abilities between discharge and six months. The improvements were significantly greater for patients treated at home (Mann-Whitney test; Barthel index, median difference 2 (95% confidence interval 0 to 3) p = 0.01; Motor Club assessment, median difference 2 (1 to 5), p = 0.01). The home treated patients received less treatment (median difference 16 (11 to 21) treatments, p less than 0.001). More than a third of patients in both groups showed depressed mood, and a quarter of care givers were emotionally distressed.

CONCLUSIONS

Home physiotherapy seems to be slightly more effective and more resource efficient than day hospital attendance and should be the preferred rehabilitation method for aftercare of stroke patients. New strategies are needed to address psychosocial function for both patients and care givers.
