Ages Eligible for Study:   18 Years to 65 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Sampling Method:   Probability Sample
Study Population
A sample of 58 veterans with paraplegia who use a rigid manual wheelchair will be recruited to participate in this study.

Inclusion Criteria:

  • level of SCI will be limited to ASIA A classification at T2 through L5 level to standardize physical capabilities,
  • SCI for at least 2 years (neurologically stable,
  • use rigid manual wheelchair as a primary means of mobility,
  • able to self-propel wheelchair,
  • able to independently transfer between wheelchair and vehicle,
  • between the ages of 18-65,
  • living in the community within 100 miles of the Tampa VA hospital,
  • able to follow simple instructions,
  • free from acute upper extremity injury for at least six months (determined by chart review) to minimize risk of injury during task performance,
  • comparable bilateral functional range of motion and strength of the shoulders, elbows and wrists (determined by physical evaluation) to minimize risk of injury during task performance.

Exclusion Criteria:

Candidates who present:

  • progressive disease (e.g. spinal tumor),
  • extended bedrest for more than 30 days,
  • ventilator-dependent,
  • any cardiac or respiratory condition that would limit subject's physical performance,
  • unstable medical conditions,
  • use of power wheelchair or scooter as primary means of mobility,
  • pregnancy,
  • clinical evidence of severe musculoskeletal disorders of the upper extremity will be precluded from participating in this study.
