1 Effects of Intramuscular Trunk Stimulation on Manual Wheelchair Propulsion Mechanics in 6 Subjects With Spinal Cord Injury  Ronald J. Triolo, PhD, Stephanie Nogan Bailey, BSE, Lisa M. Lombardo, MPT, Michael E. Miller, MS, Kevin Foglyano, BSE, Musa L. Audu, PhD  Archives of Physical Medicine and Rehabilitation  Volume 94, Issue 10, Pages (October 2013) DOI: /j.apmr Copyright © 2013 American Congress of Rehabilitation Medicine Terms and Conditions

2 Fig 1 Experimental setup for assessing effects of stimulating the trunk and hip extensors on level propulsion at self-selected speeds with instrumented pushrim and reflective markers for digital motion capture.

3 Fig 2 Average (±SD) peak resultant wheelrim force (A) and peak sagittal shoulder moment (B) with and without stimulation to the hip and trunk extensors for each subject during level self-paced propulsion. Abbreviations: Stim, stimulated; Vol, voluntary. *Statistically significant at P<.05.

4 Fig 3 Average (±SD) stroke length (A) and cadence (B) with and without stimulation to the hip and trunk extensors for each subject during level self-paced propulsion. Abbreviations: Stim, stimulated; Vol, voluntary. *Statistically significant at P<.05.

5 Fig 4 Average (±SD) FEF (A) and average maximal forward trunk lean (B) during level self-paced propulsion with and without stimulation for each subject. Abbreviations: Stim, stimulated; Vol, voluntary. *Statistically significant at P<.05.

6 Fig 5 Change in subjective perceptions of effort with activation of the hip and trunk muscles relative to propulsion without stimulation during (A) level sprints of 100m and (B) ascent of a 30.5-m ramp. S5 could not complete the ramp maneuver either with or without stimulation. *Statistically significant at P<.05.
