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.

Conditions

Spinal Cord Injury

Keywords

Biomechanics; Ergonomics; Spinal Cord Injury; Pain; Shoulder

Outcome Measures

Primary Outcomes (1)

• Shoulder Force

  measurement of applied shoulder force during wheelchair transfers

  None reported - verifiable data is not available for any of the participants

Study Arms (5)

Unassisted manual transfer

this group will use no additional aid in transfer.

Device: Unassisted Manual Transfer

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

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

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

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

Eligibility Criteria

• Age: 18 Years - 65 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)
• 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.

You may qualify if:

• 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.

You may not qualify if:

• 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.

Limitations and Caveats

PI has left facility. This study did not yield usable results due to staffing, contracting issues. Although 10 individuals signed ICs, 4 actually actively participated in the study and verifiable data is not available for any of the participants.
