Supported Treadmill Ambulation Training (STAT) for Patients Diagnosed With Amyotrophic Lateral Aclerosis

Twenty ALS patients who are independent in their transfer with assistive devise such as
walker, cane, or AFO will be offered the opportunity to participate in this study. 20
subjects will be enrolled at Carolinas ALS/Neuromuscular Center at the Carolinas HealthCare
System. Eligible subjects will return for 26 sessions, each lasting between 1-2 hours. At
Session 1 (4 weeks pre-treatment), assessments of muscle strength, spasticity, gait, and
balance will be performed, which will take between 30-60 minutes. At Sessions 2-25,
patients will do supported treadmill ambulation training at a very low speed 3 times a week
for 6 weeks under the supervision of the physical therapist. Each session will have 30
minutes of direct ambulation with the suspension system and treadmill over a 60 minute
period of time. Additionally, at sessions 13 and 26 (4 and 8 weeks post-treatment), the
assessments of muscle strength, spasticity, gait, and balance will be repeated. Needle EMG
to assess denervation potential will be performed at base line and at the conclusion of the
study. The study will last a total of 26 weeks for each patient.
