Running-specific prostheses (RSPs) enable amputees to run, but abnormal loading may pose injury risks. This study found higher impact loading in the intact limb of amputees compared to prosthetic or able-bodied limbs during running.

Area of Science:

  • Biomechanics
  • Sports Medicine
  • Rehabilitation Engineering

Background:

  • Carbon fiber running-specific prostheses (RSPs) enhance mobility for individuals with lower extremity amputation (ILEA).
  • Potential injury risks from abnormal loading during running with RSPs remain under-evaluated.
  • Vertical impact loading parameters are linked to running injuries in able-bodied individuals, but not yet in ILEA.

Purpose of the Study:

  • To investigate vertical ground reaction force (vGRF) loading in ILEA runners using RSPs across various running speeds.
  • To compare vGRF loading parameters between prosthetic limbs, intact limbs, and able-bodied limbs.

Main Methods:

  • Eight ILEA with unilateral transtibial amputations and eight control subjects ran overground at 2.5, 3.0, and 3.5 m/s.

  • Vertical impact peak (VIP) and average loading rate (VALR) were calculated from vGRF.
  • VALR was defined as the change in force divided by the time interval between 20% and 80% of the VIP.

    • Main Results:

    • Both VIP and VALR increased with running speed in all limbs (ILEA intact, ILEA prosthetic, and control).
    • ILEA intact limbs exhibited significantly greater VIP and VALR compared to their prosthetic limbs and control limbs.
    • These findings indicate speed-dependent loading increases in ILEA runners.

    Conclusions:

    • Running speed influences vertical impact loading in individuals using RSPs, similar to able-bodied runners.
    • The intact limb of ILEA may face a higher risk of running-related injuries due to elevated loading.
    • Further research is needed to understand and mitigate injury risks in ILEA runners using RSPs.
