ALS Study Determining Various Biomarkers and Strength Comparison After Exercise

Not Applicable

Completed

• Conditions: Amyotrophic Lateral Sclerosis
• Interventions: Other: Resistance Exercise Program

• Registration Number: NCT03201991
• Lead Sponsor: University of Kansas Medical Center

Brief Summary

The purpose of this study is to determine the muscle strength of a muscle in the thigh after 12 weeks of home exercise.

Detailed Description

Study participation lasts a total of three months and includes two study visits. Subjects are asked to undergo strength testing, physical exams, lab draws, and muscle biopsies at each study visit. Muscle biopsies are done in the quadriceps muscle. In between study visits, subjects are asked to maintain a weekly exercise regimen given to them by the study physical therapist.
