Brief Summary

This study will test a new technique for improving balance while walking in people with multiple sclerosis (MS). The technique focuses on having people with MS safely practice walking on simulated, uneven terrain that challenges balance and more accurately mimics walking in the community. The goal is to improve balance while walking in order to improve mobility and decrease the risk of falls. Recently, we developed a state-of-the-art treadmill system that allows us to create a challenging walking environment by placing a treadmill onto a motion base. We are able to simulate uneven terrain through movements of the walking surface while maintaining a safe walking environment. We will use this system to conduct tests of balance while walking and to train people to walk on uneven surfaces. Our objective is to evaluate the use of uneven terrain for training gait and balance in people with MS. Participants will undergo a four-week training protocol designed to disrupt and challenge balance while walking. We anticipate that training on uneven terrain will enhance gait stability, improve overall walking function and balance and increase balance confidence compared to training on a stable surface.

Outcome Measures

Primary Outcomes (3)

  • Change in Functional Gait Assessment

    The functional gait assessment (FGA) is a clinically accepted tool and is used to measure postural stability before and after the proposed walking paradigm.

    Before and after training (occurs within 5-week period)

  • Change in Dynamic Stability

    Dynamic Stability is assessed using the margin of stability (MoS). The MoS is defined as the center of mass position and velocity relative to the edge of the person's base of support. If the center of mass falls outside the base of support, the individual may require corrective action to restore balance and/or be at higher risk for loss of balance. For this study, we measured the center of mass motion and foot placement (i.e., base of support) in the medio-lateral direction to calculate each person's MoS before and after the 4-week walking sessions.

    Before and after training (occurs within 5-week period)

  • Change in Step Width

    Step width was measured for all individuals as the distance (centimeters) between the left and right ankle during double-limb support of each gait cycle. We measured step width before and after the 4-week walking sessions.

    Before and after training (occurs within 5-week period)

Secondary Outcomes (3)

  • Change in Step Length

    Before and after training (occurs within 5-week period)

  • Change in Step Frequency

    Before and after training (occurs within 5-week period)

  • Change in 10-Meter Walk Test

    Before and after training (occurs within 5-week period)

Study Arms (2)

Training Group

EXPERIMENTAL

During the 12-training day sessions, subjects will walk on the treadmill for a total of 30 minutes. Participants will walk at a comfortable pace while we perform controlled movements to the treadmill system. Subjects will be fitted with a fall-arrest harness and assisted onto the treadmill system. In the dynamic balance training group, we will move the motion base as participants walk in order to challenge their balance.

Other: Dynamic balance walking training

Control Group

NO INTERVENTION

Subjects who are in the control group will also walk on the treadmill, but the motion base will remain stationary. They will complete 12-training day sessions.

Interventions

Participants in the training group will walk on an elevated treadmill that will move side-to-side in a pseudorandom manner, thereby increasing the difficulty to their balance. Participants are asked to walk independently for 30-minutes per session, for 12 days over 4 weeks.
