Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The presence of foot drop limits normal gait. Our prior data has suggested that approximately 30% of MS patients have foot drop. Although we have observed that "task-specific" rehabilitation using the Lokomat can improve ambulation in chronic MS patients, subjects with "foot drop" have difficulty translating task-specific training to normative gait patterns over ground, despite improving speed and endurance.

One of the key limitations of the Lokomat is a lack of robot-assisted training for the ankle joint. The Anklebot, an MIT-developed rehabilitation robot for the ankle, has the potential to address this. The device can move throughout three planes and train ankle flexion, extension, inversion and eversion; however, therapy with the Anklebot alone does not train the knee or hip.

We plan to test whether subject foot drop and overall gait benefit more from Anklebot therapy alone or a combination of Anklebot and Lokomat.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Arm 1

Anklebot

Group Type EXPERIMENTAL

Anklebot

Intervention Type DEVICE

The Ankle-Bot (Wheeler et al., 2004) is a stand-alone robot assisted device that is worn via a leather boot and knee brace (Fig.1). The Ankle-Bot can assist ankle movement throughout 3 planes. The percentage of force generated by the Ankle-Bot can be adjusted from no help, 0% assistance to 100% assistance. The device is low impedance and a subject can easily over come the forces generated by the Ankle-Bot. The Ankle-Bot will guide and assist the subject into ankle flexion, extension, inversion and eversion.

Arm 2

Body-weight supported treadmill training

Group Type EXPERIMENTAL

Lokomat

Intervention Type DEVICE

The Lokomat is a motor driven exoskeleton device that employs a body weight support suspension system and treadmill .

Arm 3

Combination therapy (Anklebot and BWSTT)

Group Type EXPERIMENTAL

Anklebot

Intervention Type DEVICE

The Ankle-Bot (Wheeler et al., 2004) is a stand-alone robot assisted device that is worn via a leather boot and knee brace (Fig.1). The Ankle-Bot can assist ankle movement throughout 3 planes.
