Summary

Post-stroke patients exhibit persistent postural instability for up to 4 years, even with full motor recovery. Older adults (>65) show greater balance deficits than younger stroke survivors.

Area of Science:

  • Neurology
  • Rehabilitation Medicine
  • Biomechanics

Background:

  • Balance disturbances frequently persist after stroke, impacting functional recovery.
  • Full recovery of the paretic limb does not guarantee resolution of postural instability.

Purpose of the Study:

  • To quantify the duration of detectable postural instability post-stroke.
  • To compare postural control differences between younger (<65) and older (>65) post-stroke individuals.

Main Methods:

  • Employed static and dynamic posturography to assess balance control.
  • Evaluated 29 stroke patients (mean 3-4.7 years post-stroke) and 38 healthy controls.

Main Results:

  • Older stroke patients (>65) demonstrated significantly impaired static and dynamic balance compared to controls.
  • Younger stroke patients (<65) showed elevated dynamic posturography parameters (pathway, velocity) versus controls.

Conclusions:

  • Postural instability is a significant and persistent issue in stroke survivors, detectable for years.
  • Age influences the degree of postural instability following stroke, with older individuals experiencing greater deficits.
