Botulinum toxin A for treatment of upper limb spasticity following stroke: A multi-centre randomized placebo-controlled study of the effects on quality of life and other person-centred outcomes. [Journal Article]
J Rehabil Med 2009 Jun; 41(7):536-44.
OBJECTIVE: Botulinum toxin is known to relieve upper limb spasticity, which is a disabling complication of stroke. We examined its effect on quality of life and other person-centred perspectives.
DESIGN: A multi-centre, randomized, double-blind, placebo-controlled study.
PATIENTS: Ninety-six patients were randomized (mean age 59.5 years) at least 6 months post-stroke. Mean time since stroke was 5.9 years.
METHODS: Patients received either botulinum toxin type A or placebo into the affected distal upper limb muscles on 2 occasions, 12 weeks apart. Assessment was undertaken at baseline, 8, 12, 20 and 24 weeks. The primary outcome measure was the Assessment of Quality of Life scale (AQoL). Secondary outcome assessments included Goal Attainment Scaling (GAS), pain, mood, global benefit, Modified Ashworth Scale (MAS), disability and carer burden.
RESULTS: The groups did not differ significantly with respect to quality of life, pain, mood, disability or carer burden. However, patients treated with botulinum toxin type A had significantly greater reduction in spasticity (MAS) (p.
