Summary
Older dysvascular amputees exhibit greater turning instability and slower turn times compared to traumatic amputees. This highlights a need for targeted rehabilitation strategies for dysvascular individuals, especially for prosthetic-side turns.
Area of Science:
- Biomechanics
- Rehabilitation Medicine
- Amputee Mobility
Background:
- Turning is a significant challenge for individuals with lower limb loss.
- Older dysvascular amputees face greater difficulties with turning compared to traumatic amputees.
Purpose of the Study:
- To compare the turning performance between dysvascular and traumatic transtibial amputees.
- To identify specific turning deficits in dysvascular amputees.
Main Methods:
- Six dysvascular and six traumatic transtibial amputees participated.
- Evaluated using the NeuroCom Balance Master's Step Quick Turn test and the Timed Up and Go Test.
- Measured turn time, turn sway, and 180° turning ability to prosthetic and sound sides.
Main Results:
- Dysvascular amputees showed significantly greater turn sway on both prosthetic (70.7 ± 14.2 vs. 43.3 ± 9.7) and sound sides (72.5 ± 16.1 vs. 43.5 ± 8.2).
- Turn times were significantly longer for dysvascular amputees on both prosthetic (4.1 ± 1.4 vs. 1.7 ± 0.46) and sound sides (4.0 ± 1.3 vs. 2.1 ± 0.5).
- No significant differences were found in the Timed Up and Go Test results between groups.
Conclusions:
- Dysvascular amputees demonstrate impaired turning ability, indicating reduced adaptation to turning challenges.
- Rehabilitation programs for dysvascular amputees should emphasize turning tasks, particularly those involving the prosthetic limb.

01:31Diabetic Foot Ulcer
Definition A diabetic foot ulcer (DFU) is a chronic, non-healing wound that develops in individuals with diabetes. It typically occurs on pressure-bearing areas such as the heel, metatarsal heads, or hallux, and carries a high risk of infection and amputation.Pathophysiology • The development of DFUs can be explained by four interconnected mechanisms: neuropathy, ischemia, infection, and impaired wound healing. • Neuropathy is the most common factor. Sensory neuropathy reduces pain perception,...
