Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
An evidence-based therapy program is provided for 12 weeks immediately following botulinum toxin-A injection. The program commences with:
(1) Up to 3 serial casts applied to place the wrist in maximum extension for 2 weeks. Cast is applied the first working day following botulinum toxin-A injection; followed by
(2) 10 weeks of movement training, aimed at decreasing weakness (electrical stimulation and progressive resistance exercises) and improving movement (task-specific practice). Participants are encouraged to practice for 1 hour per day, 7 days a week during the 10 weeks (ie, approximately 70 hours in total inclusive of clinic based sessions). Participants are supported by a mix of clinic-based sessions, home visits, and phone calls. Clinic-based sessions will be conducted by a trained physical or occupational therapist (duration 1 hour, frequency decreasing (3 x per week initially, but decreasing to 1 x week by week 7)). Participants will receive a booklet outlining their movement training and a training log to record the number of minutes of practice daily.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
For each clinic, allocation will occur in random permuted blocks so that after every block (of 4-8 participants), the experimental and control group will contain equal numbers. Randomization will occur after injection of botulinum toxin-A. The schedule will be stored off-site and group allocation will be revealed online.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization will be computer-generated, independent and concealed. The allocation sequence has been generated and will be managed by the Griffith Randomistation Service at Griffith University.

Summary
Brief summary
Impaired arm and hand function is a common and often devastating problem for stroke survivors. Regaining lost movement in the arm/hand is more difficult to achieve than walking, with only 5% of people with hemiplegia regaining functional use of their hand. This devastating outcome could potentially be addressed, however we do not yet know how to best increase movement in the arm and hand after stroke for patients with spasticity.

There is a lack of randomized controlled trials of botulinum toxin A (BoNT-A) with a group who does not receive therapy in some dose, and so whether gains were achieved through BoNT-A or a combination of the BoNT-A and therapy cannot be determined from the studies to date.The research project is testing whether intense therapy given after botulinum toxin injections into the arm is more helpful than just the injections alone.
