Brief Summary

It has been found that arm and leg cycling is similar to walking in terms of the muscle activation patterns and joint ranges of motion. In addition, arm and leg cycling and walking activate similar neural pathways. Another advantage of arm and leg cycling is that it involves coordination of all four limbs in a rhythmic movement. This may be particularly beneficial given previous findings that arm movement contributes to the activation of leg muscles during walking in humans. This is achieved with interconnected neural pathways that link the arms to the legs. These neural interlimb connections remain intact in stroke victims, such that maximizing the contribution of the arms to the legs may increase coordination for walking. Thus, the objectives of this research are to determine if arm and leg cycling can be used to increase the strength of interlimb connections and if this helps to improve walking ability in a post-stroke population. It is hypothesized that arm and leg cycling will transfer to improvements in walking in a post stroke population.

Outcome Measures

Primary Outcomes (1)

• Change in Treadmill Walking Characteristics

  Treadmill walking characteristics will be gauged via a customized analysis of muscle activity patterns and lower limb joint kinematics. Walking frequency, symmetry, and timing will also be analyzed

  Baseline, immediately post-intervention (average of 4 days following last exercise session)

Secondary Outcomes (6)

• Interlimb Connections

  Baseline, immediately post-intervention (average of 4 days following the last exercise session)

• Fugl-Meyer Assessment

  Baseline, immediately post-intervention (average of 4 days following the last exercise session)

• Brunnstrom recovery stages

  Baseline, immediately post-intervention (average of 4 days following the last exercise session)

• Timed up and go test

  Baseline, immediately post-intervention (average of 4 days following the last exercise session)

• 10 meter walk test

  Baseline, immediately post-intervention (average of 4 days following the last exercise session)

Study Arms (1)

Arm and Leg Cycling Exercise Program

EXPERIMENTAL

Multiple baseline test sessions will be used for the same participant to establish a meaningful baseline thus confirming consistency of all outcome measures prior to the intervention.

Behavioral: Arm and Leg Cycling Exercise Program

Interventions

Arm and Leg Cycling Exercise Program BEHAVIORAL

Participants will perform arm and leg cycling training three times a week, with 30 minutes of aggregate exercise time per session. To evaluate the physiological cost of exercise, heart rate and a rating of perceived exertion will be collected. The progressive element of this training will include increasing the resistance of the ergometer over the six weeks in order to maintain the same relative exercise stress.
