NCT04877249

Brief Summary

The focus of this study is to optimize the delivery of a combined strength and aerobic training regimen to individuals with post stroke hemiparesis and reduce overuse and inefficiencies associated with the nonparetic leg during walking. This study proposes to use 1) split-belt treadmill and 2) single belt treadmill walking using split belt simulation software for enhancing symmetrical walking patterns for people with stroke.

Outcome Measures

Primary Outcomes (8)

  • Bilateral symmetry of ground reaction forces during split-belt treadmill walking

    Vertical, horizontal, and mediolateral ground reaction force changes will be measured in response to split/tied belt speed and with (or without) a resistance using the Bertec split-belt, force plates instrumented treadmill and the Vicon 3D motion analysis system.

    Single point of assessment in one day and ground reaction forces will be recorded continuously for 20-30minutes and will be expressed per gait cycle

  • Bilateral symmetry of joint torques during split-belt treadmill walking

    Joint torques changes of ankle, knee, and hip joints will be measured in response to split/tied belt speed and with (or without) a resistance using the Bertec split-belt, force plates instrumented treadmill and the Vicon 3D motion analysis system.

    Single point of assessment in one day and joint torques will be recorded continuously for 20-30minutes and will be expressed per gait cycle

  • Trailing limb angle during split-belt treadmill walking

    Peak trailing limb angle changes will be measured in response to split/tied belt speed and with (or without) a resistance using the Bertec split-belt, force plates instrumented treadmill and the Vicon 3D motion analysis system.

    Single point of assessment in one day and trailing limb angle will be recorded continuously for 20-30minutes and will be expressed per gait cycle

  • Bilateral muscles activities during split-belt treadmill walking

    Timing (milliseconds) of Soleus, Tibialis Anterior, and Quadriceps muscle activities changes will be recorded continuously in response to split/tied belt speed and with (or without) a resistance using Delsys wireless EMG system.

    Single point of assessment in one day and muscle activity will be recorded continuously for 20-30minutes and will be expressed per gait cycle

  • Bilateral muscles activities during split-belt treadmill walking

    Peak amplitude (millivolts) of Soleus, Tibialis Anterior, and Quadriceps muscle activities changes will be recorded continuously in response to split/tied belt speed and with (or without) a resistance using Delsys wireless EMG system.

    Single point of assessment in one day and muscle activity will be recorded continuously for 20-30minutes and will be expressed per gait cycle

  • Spatiotemporal patterns during split-belt treadmill walking

    Cadence (Step numbers/minute) during split/tied treadmill walking will be recorded continuously using the Vicon 3D motion analysis system.

    Single point of assessment in one day and spatiotemporal gait parameters will be recorded continuously for 20-30minutes and will be expressed per gait cycle.

  • Spatiotemporal patterns during split-belt treadmill walking

    Step and stride length (cm) during split/tied treadmill walking will be recorded continuously using the Vicon 3D motion analysis system.

    Single point of assessment in one day and spatiotemporal gait parameters will be recorded continuously for 20-30minutes and will be expressed per gait cycle.

  • Spatiotemporal patterns during split-belt treadmill walking

    Stance and swing time (sec) during split/tied treadmill walking will be recorded continuously using the Vicon 3D motion analysis system.

    Single point of assessment in one day and spatiotemporal gait parameters will be recorded continuously for 20-30minutes and will be expressed per gait cycle.
