Abstract

127 patients with amputated thumbs or fingers between the level of the DIP and MP joints were followed up at regular intervals until one year after injury. Sensory disturbances subsided rapidly except for numbness which was still present in 50% at one year. Range of movement was regained early. Although pronation and supination improved to 70% only a few months after injury, it took a year for power grip and key pinch to regain 70%. Further analysis showed that power grip was worst in amputees of multiple fingers, thumb, and the middle finger through the proximal phalanx. For key pinch, almost all were impaired to a level of 50% to 60%. Multiple finger amputees also had decreased pronation, and thumb amputees had decreased supination. Other factors were not significant. One-quarter had to change their jobs and one-fifth showed concern with the appearance.

Occupational therapy for stroke patients not admitted to hospital: a randomised controlled trial.

BACKGROUND: Patients who have a stroke are not always admitted to hospital, and 22-60% remain in the community, frequently without coordinated rehabilitation. We aimed to assess the efficacy of an occupational therapy intervention for patients with stroke who were not admitted to hospital. METHODS: In this single-blind randomised controlled trial, consecutive stroke patients on a UK community register in Nottingham and Derbyshire were allocated randomly to up to 5 months of occupational therapy at home or to no intervention (control group) 1 month after their stroke. The aim of the occupational therapy was to encourage independence in personal and instrumental activities of daily living. Patients were assessed on outcome measures at baseline (before randomisation) and at 6 months. The primary outcome measure was the score on the extended activities of daily living (EADL) scale at 6 months. Other outcome measures included the Barthel index, the general health questionnaire 28, the carer strain index, and the London handicap scale. All assessments were done by an independent assessor who was unaware of treatment allocation. The analysis included only data from completed questionnaires. FINDINGS: 185 patients were included: 94 in the occupational therapy group and 91 in the control group. 22 patients were not assessed at 6 months. At follow-up, patients who had occupational therapy had significantly higher median scores than the controls on: the EADL scale (16 vs 12, p<0.01, estimated difference 3 [95% CI 1 to 4]); the Barthel index (20 vs 18, p<0.01, difference 1, [0-1]); the carer strain index (1 vs 3, p<0.05, difference 1 [0 to 2]); and the London handicap scale (76 vs 65, p<0.05, difference 7, [0.3 to 13.5]). There were no significant differences on the general health questionnaire between the patient or carer. INTERPRETATION: Occupational therapy significantly reduced disability and handicap in patients with stroke who were not admitted to hospital.

A 3-year randomized trial of ropinirole and bromocriptine in early Parkinson's disease. The 053 Study Group.

OBJECTIVE: To compare the long-term efficacy and safety of ropinirole with bromocriptine over 3 years in patients with early PD with limited or no previous dopaminergic therapy. METHODS: In this prospective, double-blind, parallel-group study, 335 patients were randomized to 0.75 mg ropinirole or 1.25 mg bromocriptine titrated upward at weekly intervals--maximum permitted daily doses were 24 mg ropinirole, 40 mg bromocriptine. RESULTS: Approximately one third of patients in each group withdrew prematurely, mostly because of adverse experiences; 61/102 (60%) of ropinirole-treated and 59/112 (53%) of bromocriptine-treated patients completed the study on the dopamine agonist alone. Mean doses for all patients at completion were 12 mg (SD 6) ropinirole and 24 mg (SD 8) bromocriptine. Occurrence of adverse experiences in both groups was similar. Emergence of dyskinesias was low. Both treatments induced marked improvements in Unified Parkinson's Disease Rating Scale activities of daily living (ADL, Part II) and motor (Part III) scores over the first 12 weeks, which were maintained during the study. After 3 years, patients in the ropinirole group had a mean improvement in motor score of 31% compared with 22% in the bromocriptine group (p = 0.086) and a significantly better ADL score (treatment difference 1.46 points, p = 0.009) [corrected]. CONCLUSIONS: Both dopamine agonists are effective in the early treatment of a high proportion of PD patients; effectiveness persists for at least 3 years. Those who completed the study had a significantly better functional status on ropinirole than on bromocriptine.

Residual physical outcome and daily living 3 to 6 years after Guillain-Barré syndrome.

Three to six years after onset of Guillain-Barré syndrome, 63% of 122 patients showed one or more changes in their lifestyle, work, or leisure activities, or in the life of their partners. The changes were influenced by an impaired final functional outcome, along with loss of power and poor condition, although physically recovered patients showed these changes as well.
