Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
After informed consent has been received and the intial measurements completed the group allocation will be determined by ringing a contact person off-site who will open a sealed opaque envelope to inform of group allocation
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
External person not involved in recruitment, intervention or measurement will generate the sequence using Excel software
Masking / blinding

Summary
Brief summary
People who have had a severe stroke generally remain very disabled. An EMG triggered electrical stimulation machine measures electrical activity in muscles and provides electrical stimulation when a threshold level of muscle activity is reached, hence it provides feedback to people with weak muscles and strengthens muscles. Seventy very weak, acute stroke patients will be allocated to receive EMG triggered electrical stimulation to muscles of their arm in addition to conventional therapy or conventional therapy only. Measures of muscle strength and activity will be taken before and after the intervention. This intervention has the potential to increase the likelihood of returning to independence after a severe stroke.
