Clinical Application of Cross-education During Stroke Rehabilitation "X-Ed-Stroke01"

Phase N/A Results N/A

Trial Description

Based on the current state of knowledge and gaps in the literature we will conduct an intervention study to explore novel treatment and rehabilitation of patients at Royal University Hospital (RUH) with motor deficits following stroke. This project has the following objectives:
1. To determine if cross-education, in addition to standard rehabilitation leads to better recovery of upper limb function for stroke patients with hemiparesis.
2. To incorporate functional brain activation as measured by functional magnetic resonance imaging (fMRI) to examine the neural mechanisms associated with changes in motor function of the paretic arm post-stroke.
3. To use diffusion tensor imaging (DTI) tractography to measure connectivity and examine the extent to which white matter tract thickness correlates with preserved motor output in patients post-stroke.

Conditions

Interventions

  • Cross-education + standard rehabilitation Other
    ARM 1: Kind: Experimental
    Label: cross-education + standard rehabilitation
    Description: The cross-education group will engage in strength training of the non-paretic hand in addition to standard rehabilitation. Cross-education will be progressive in nature, beginning with 2 sets of 8 repetitions and increasing up to a maximum of 6 sets of 8 repetitions of maximal voluntary effort isometric handgrip contractions as tolerated. Grip training will be performed using standard grip trainers (Digi-Flex Grip trainers) to train both finger flexors and full hand and wrist isometric contractions. In addition, patients will perform controlled dynamic wrist flexion and extension training of the non-paretic hand using exercise tubing with the same prescription. Patients will be asked to complete exercises 3 times per week for 26 weeks, and to record adherence in a training log. An average of one session per week will be considered 'trained'.
