Official title

Comparing the Effect of a Graded Repetitive Arm Supplementary Home-based Exercise Programme With COgnitive-somatoSensory-MOtor Training to Improve Arm and Hand Function After Stroke (iCOSMO)

Overview

The iCOSMO study investigates the feasibility and beneficial effects of an intervention combining sensation, motor and cognition to improve arm and hand function after chronic stroke.

Detailed description

The iCOSMO is a two-arm randomized controlled trial study evaluating the feasibility and efficacy of combined somatosensory-motor intervention using a cognitive approach to improve upper limb recovery in people with chronic stroke. Forty participants will be recruited (20 in experimental group and 20 in the control group). iCOSMO will include active touch and movement exploratory procedures during goal-oriented tasks as well as robotic training using the Kinarm Exoskeleton device. The experimental group will receive a total of 36 hours of treatment (6 weeks). The control group will receive a matched dose of a home-based motor exercise programme. The outcome measures will include measures of feasibility such as the recruitment and adherence rates and standardised clinical and robotic assessments. The participants will be tested at the start and end of the baseline phase, at post-intervention and at 1-month follow-up.

Interventions

  • Other Home Graded Repetitive Arm Supplementary Program (GRASP)
    The home-based exercise programme will be based on the Home Graded Repetitive Arm Supplementary Program focusing on stretching, arm strengthening, hand strengthening, coordination and hand skills. The Home Graded Repetitive Arm Supplementary Program will be delivered 2 hours/session, 3 times/week, for 6 weeks.
  • Other integrated Somatosensory-MOtor training using a COgnitive approach(iCOSMO)
    The first training approach of iCOSMO will focus on integrated somatosensory-motor variables during reaching and object manipulation (60 minutes). The second training approach will focus on proprioceptive, motor and cognitive tasks using the Kinarm robotic exoskeleton (60 minutes). iCOSMO will be delivered 3 times per week (2 hours per session) for 6 weeks (Total: 36 hours of treatment).
