Benchmark data for elderly, vascular trans-tibial amputees after rehabilitation

Area of Science:

• Biomechanics
• Prosthetics and Orthotics
• Geriatric Rehabilitation

Background:

• Existing lower limb amputee gait data primarily features young, trauma-related amputees.
• Elderly vascular amputees, a majority demographic, exhibit distinct gait characteristics.
• Lack of benchmark data hinders comparison of rehabilitation strategies and prosthetic devices.

Purpose of the Study:

• To establish kinetic and kinematic benchmark data for elderly vascular trans-tibial amputees.
• To investigate relationships between gait speed, consistency, and functional outcomes.
• To identify unique gait patterns in this population.

Main Methods:

• Kinetic and kinematic gait parameters were measured in 20 elderly vascular trans-tibial amputees.
• Participants were at least six months post-amputation.
• Data was collected from The Queen Elizabeth Centre, Ballarat, Australia.

Main Results:

• Significant relationships were found between gait speed, consistency, and functional ability.
• Elderly vascular amputees demonstrated distinct gait characteristics compared to younger cohorts.
• An unusual vertical ground reaction force pattern was observed in faster, more functional individuals.

Conclusions:

• This study provides essential benchmark biomechanical data for elderly vascular trans-tibial amputees.
• Understanding these specific gait patterns is vital for effective rehabilitation and prosthetic prescription.
• Further research is needed to elucidate the unexplained vertical ground reaction force pattern.
