Summary
Sensory changes, including impaired superficial pain and vibration, are common in adults with unilateral transtibial amputation (TTA). Age impacts these sensory deficits, particularly in older individuals using prosthetics.
Area of Science:
- Neuroscience
- Rehabilitation Medicine
- Prosthetics
Background:
- Sensory changes post-amputation can hinder prosthetic use.
- Understanding these changes is crucial for successful rehabilitation.
Purpose of the Study:
- To describe sensory changes in adults with unilateral transtibial amputation (TTA).
- To assess the impact of amputation and prosthetic use on tactile and pain sensation.
Main Methods:
- Evaluated light touch, deep pressure, vibration, and superficial pain in 16 veterans with TTA.
- Sensory testing was performed on both residual and contralateral limbs.
Main Results:
- Six subjects showed impaired sensation (superficial pain, vibration, light touch) in the residual limb.
- Superficial pain was the most frequently impaired modality.
- Impairment of vibration and superficial pain sensation correlated with age.
Conclusions:
- Deep pressure sensation remained intact in all subjects.
- Amputation and prosthetic use minimally impaired light touch and vibration sensation.
- Significant impairment of superficial pain sensation was observed, suggesting a need for targeted interventions.
