Summary

Older age negatively impacts physical function and prosthesis use in lower-limb amputees. Stump length benefits below-knee amputees, while smoking hinders mobility in male vascular amputees.

Area of Science:

  • Rehabilitation Medicine
  • Orthopedics
  • Biomedical Engineering

Background:

  • Lower-limb amputation significantly affects patient mobility and quality of life.
  • Understanding factors influencing functional recovery is crucial for effective rehabilitation.

Purpose of the Study:

  • To investigate the relationship between various factors and functional outcomes in lower-limb amputees one year post-surgery.
  • To identify predictors of prosthetic use and mobility.

Main Methods:

  • A cohort of 125 lower-limb amputees was assessed one year post-surgery.
  • Personal interviews and physical examinations were conducted.
  • Multiple linear regression and partial correlation analyses were employed to analyze data.

Main Results:

  • Increasing age was unfavorably associated with walking distance, walking time, outdoor ambulation, need for walking aids, and prosthesis use.
  • Longer stump length in below-knee amputees correlated with greater walking distance.
  • Smoking in male vascular below-knee amputees showed negative associations with walking distance, outdoor ambulation, and walking time.
  • No variables significantly related to the postoperative accommodation situation.

Conclusions:

  • Age is a significant negative predictor of functional recovery and prosthetic use after lower-limb amputation.
  • Stump length and smoking habits are important considerations in the rehabilitation of below-knee amputees.
  • Further research may explore interventions to mitigate age-related functional decline and address modifiable risk factors like smoking.
