The Effects of Plantar Flexion Training on Plantar Flexion Activation, Torque, and Step Length Asymmetry in People With Chronic Stroke
This study consists of three phases that aim to develop an exercise intervention to promote
maximal activation of ankle plantar flexors in the paretic lower extrimty (LE) in order to
restore a more normalized gait pattern in chronic stroke survivors.
The aim of the first phase is to determine if there are differences between standing on
different levels of inclination on plantar flexion activation during forward movement of the
contralateral LE in adults with chronic with stroke.
The aim of second phase is to determine if there are differences between different
percentages of weight bearing on the paretic LE on plantar flexion activation during forward
movement of the contralateral LE in adults with chronic stroke.
The aim of the third phase is to determine if there are differences between a 4-week plantar
flexion training intervention and conventional physical therapy.

Description of Arms:
This study has three phases. The first phase is performed in a cross-over fashion.
Participants will stand on two different incline angles on the paretic LE and simultaneously
move a small skateboard forward with the non-paretic LE. The testing order for the two
different incline angles will be randomized, and all participants will be required to
complete both incline angle conditions within a single test session.
The second phase will also be performed in a cross-over fashion. Participants will stand with
three different percentages of body weight on their paretic LE while moving the skateboard
forward with the non-paretic LE. The testing order for the three body weight percentages will
be randomized. All participants will be required to complete all three body weight conditions
within a single test session.
In the third phase, participants will be randomized to either a control 4-week exercise
intervention (conventional physical therapy) or a 4-week experimental exercise intervention
(plantar flexion training). Both the control and exerimental arms will complete over-ground
multi-directional gait training and home exercise.
