Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Arm1: virtual myoelectric exoskeleton involving active assisted upper limb movements whilst the patient is immersed in a virtual reality environment that requires the patient to interact with a serious game. The virtual reality system with a serious game used in this platform is an immersive virtual reality (VR) system with two VR environments: one is a kitchen where the aim is to perform functional tasks such as taking a bottle; the other involves a boat with holes that the patient has to close to prevent water entry. These two environments are coupled with the electromyography driven exoesqueleton allowing patients to receive assistance with upper limb movements whilst performing tasks in a realistic virtual environment. In addition patients will receive balance and gait reeducation exercises (e.g. standing over an unstable surface; weight transfer between limbs; treadmill walking with feedback and assistance from physiotherapist). Total intervention time is 50 minutes (30 mins with exoskeleton assisted upper limb reeducation in VR environment, 10 minutes gait reeducation, 10 mins balance re-education).

Arm2: active upper limb movements whilst the patient is exposed to the illusion caused by a mirror box. In addition patients will perform the same movements performed by patients in arm1 with the exoskeleton but with the assistance of a Physiotherapist rather than the exoskeleton. In addition patients will receive balance and gait reeducation exercises. Total intervention time is 50 minutes (30 mins upper limb re-education with mirror illusion and active assisted movements, 10 mins gait reeducation, 10 mins balance re-education)

Arn3: conventional therapy, 50 minutes (30 upper limb re-education involving active and passive movements, 10 minutes gait reeducation, 10 mins balance reeducation).

All interventions will be 50 minutes per day, 5 days a week (Monday to Friday), for 8 weeks. Interventions will be delivered at the Rehabilitation Unit of a large Hospital by Physiotherapists specialised in neurological rehabilitation. Adherence will be measured as days attending treatment.

50 minutes of conventional Physiotherapy 50 minutes per day, 5 days a week (Monday to Friday), for 8 weeks.. The intervention involves upper limb functional reeducation (active and passive upper limb movements), and balance and gait reeducation (e.g. standing over an unstable surface; weight transfer between limbs; treadmill walking with feedback and assistance from physiotherapist), The interventions will be delivered at the Rehabilitation Unit of a large Hospital by Physiotherapists specialised in neurological rehabilitation.

Outcomes
Primary outcome [1] 304984 0
Muscle activation amplitude of deltoid during upper limb movements described in the Fugl Meyer scale. Fugl Meyer is a scale normally used to measure upper limb function, however sometimes the scale is not sensitive enough to detect changes. Surface electromyography measurement during this test should provided more detailed information about muscle function recovery.
