Progressive Strength Training in Spinal Muscular Atrophy

This study has been completed.

University of Utah Identifier:
First received: October 19, 2010

Last verified: May 2017
The proposed feasibility study is necessary to test if children and young adults will participate in and adhere to a 12-week, home-based, supervised progressive strength training exercise program and to obtain preliminary data that will subsequently allow us to determine the safety and impact of strength training in spinal muscular atrophy. Our pilot study will address 3 aims: (1) Ascertain the feasibility of, and potential barriers to, participation in and adherence to a 12-week home-based, supervised, progressive strength training exercise program in children and young adults aged 5-21 years with SMA types II and III; (2) Determine the safety and tolerability of progressive strength training in a pilot study sample of children and young adults with SMA types II and III; and (3) Determine candidate outcome measures.

Primary Outcome Measures:
  • Strength [ Time Frame: 12 weeks ]
    Primary Outcome Measure was muscle strength. Strength was measured using a fixed myometry evaluation, quantitative muscle analysis (QMA). QMA utilizes a relative fixed point for the participant to exert effort. Each muscle of interest was tested using QMA.

Enrollment: 12
Actual Study Start Date: June 2010
Study Completion Date: June 2013
Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Spinal muscular atrophy
Children and adolescents with diagnosis of SMA type II or III. The intervention group (the only arm/group in this pilot study) receives a home-based, supervised, 12-week progressive strength-training program.
Other: Progressive strength training
the systematic increase in resistance weights
