Participant Flow

5 individuals with spinal cord injury: recruited from University of Pittsburgh Physical Medicine \& Rehabilitation research registry. 3 individuals with amyotrophic lateral sclerosis: recruited from University of Pittsburgh/UPMC neurologist, David Lacomis, MD.

All individuals were safety screened and underwent functional magnetic resonance imaging. No individuals were excluded.

Participant milestones

Participant milestones
Measure
S1/ SCI Participants: fMRI w/ Motor or Sensory Imagery
Individuals will be asked to attempt finger and hand movements while fMRI is used to measure brain activity. Motor or sensory imagery: Brain activity will be measured using fMRI while participants imagine different movements or sensations in order to assess the organization of sensorimotor cortical activity after injury.
M1/ ALS: fMRI w/ Motor or Sensory Imagery
Individuals will be asked to attempt ankle, knee, toe, and hand movements while fMRI is used to measure brain activity. Motor or sensory imagery: Brain activity will be measured using fMRI while participants imagine different movements or sensations in order to assess the organization of sensorimotor cortical activity.
