Robot Aided Rehabilitation - Intervention

Summary

Sensorimotor impairments following stroke often involve complex pathological changes across multiple joints and multiple degrees of freedom of the arm and hand, thereby rendering them difficult to diagnose and treat. The objective of this study is to evaluate multi-joint neuromechanical impairments in the arm and hand, then conduct impairment-specific treatment, and determine the effects of arm versus hand training and the effects of passive stretching before active movement training.

Conditions

• Stroke

Interventions

OTHER

Passive stretching

Prior to active training, subjects will be passively move their arm or hand by IntelliArm or the hand robot within preset ranges of motion.

OTHER

Passive movement

Prior to active training, subjects will be passively move their arm or hand by IntelliArm or the hand robot only within ranges that produce no to very minimal forces.

OTHER

IntelliArm

During the active training, subjects will be asked to actively move their arm while supported with IntelliArm robot to interact with virtual targets and objects. The IntelliArm may provide resistance or assistance.

OTHER

Hand robot

During the active training, subjects will be asked to actively open and close their hand with the hand robot on while participating in task oriented occupational therapy focused on grasp and release tasks. The hand robot may provide resistance or assistance.
