Brief Summary:
This is a laboratory-based study to evaluate the risk of shoulder injury associated with transfers between wheelchair and vehicle in persons with spinal cord injury. Four new devices will be compared against an unassisted transfer.

Condition or disease Intervention/treatment
Spinal Cord Injury Device: Unassisted Manual Transfer Device: Standard Transfer Board Device: Glide n' Go Device: Easy Reach lift Device: Ryno lift

Group/Cohort Intervention/treatment
Unassisted manual transfer
this group will use no additional aid in transfer.
Device: Unassisted Manual Transfer
No device assistance
Standard sliding board transfer
The standard transfer board is a flat surface board designed to bridge the gap that exists with transfers from wheelchair to vehicle and/or other horizontally displaced seating surfaces.
Device: Standard Transfer Board
Flat surface board
Glide n' Go Lift
The Glide n' Go lift is a flip down power list seat that enables the person to enter and exit the vehicle by lifting them from their wheelchair up tot eh vehicle seat that they can make an easy transfer into the vehicle. Trunk stability may be required to successfully use the device.
Device: Glide n' Go
Flip down power lift chair
Easy Reach lift
The Easy Reach lift seat allows the vehicles original seat to swivel out of the vehicle and lower to wheelchair height. the chair extends far from the vehicle to provide access for a safe, easy transfer.
Device: Easy Reach lift
Original chair is converted to a chair that swivels out of the vehicle and lowers to wheelchair height
Ryno lift
The Ryno lift is an under-vehicle list (UVL) system. Using this lift, the wheelchair user is raised into the vehicle cab using independent controls and can then maneuver into a convenient position in the cab. The wheelchair is locked down and the lift stored beneath the vehicle chassis. This technology eliminated the need to store and retrieve a wheelchair during transit.
Device: Ryno lift
Lift for the wheelchair

Primary Outcome Measures :
  1. Shoulder Force [ Time Frame: None reported - verifiable data is not available for any of the participants ]
    measurement of applied shoulder force during wheelchair transfers

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.
