Ankle foot orthoses (AFOs) can improve static balance in patients with multiple sclerosis (MS). However, dynamic balance may be impaired, particularly with static AFOs, though dynamic AFOs show less negative impact.

Area of Science:

  • Neuroscience
  • Rehabilitation Medicine
  • Biomechanics

Background:

  • Patients with multiple sclerosis (MS) often experience balance disorders affecting mobility.
  • Ankle foot orthoses (AFOs) are used to support lower limb function.
  • Understanding the impact of ankle joint motion restriction on balance is crucial for rehabilitation.

Purpose of the Study:

  • To investigate if limiting ankle joint degrees of freedom with AFOs can improve standing and walking balance in MS patients.
  • To compare the effects of static AFOs versus dynamic AFOs on balance.

Main Methods:

  • A crossover design study was conducted with 14 MS patients with balance deficits.
  • Participants were tested barefoot, with static AFOs, and with dynamic AFOs (allowing plantar flexion).

  • Static and dynamic balance tests were performed under all three conditions.

    • Main Results:

    • Static balance improved significantly with both types of AFOs, particularly dynamic AFOs.
    • Dynamic balance was impaired with static AFOs, increasing walking time by 172%.
    • Dynamic AFOs showed a less negative impact on dynamic balance (113% increase in walking time).

    Conclusions:

    • Both static and dynamic AFOs enhance static balance in MS patients.
    • Static AFOs significantly impair dynamic balance during walking.
    • Dynamic AFOs offer a better compromise, improving static balance with less detriment to dynamic balance.
