Summary

Spasticity affects 38% of stroke survivors 12 months post-stroke, impacting functional ability. Comprehensive assessment of both arms and legs is crucial for accurate prevalence estimation.

Area of Science:

  • Neurology
  • Rehabilitation Medicine
  • Clinical Epidemiology

Background:

  • Stroke is a leading cause of long-term disability.
  • Spasticity, characterized by increased muscle tone, is a common post-stroke complication.
  • Accurate prevalence data and understanding its impact on function are vital for effective management.

Purpose of the Study:

  • To determine the prevalence of spasticity 12 months after stroke.
  • To investigate the relationship between spasticity and functional ability in stroke survivors.

Main Methods:

  • A cohort study involving 106 community-dwelling stroke survivors in Liverpool, UK.
  • Spasticity assessed using the Modified Ashworth Scale (MAS) and Tone Assessment Scale (TAS) at multiple joints.
  • Functional ability measured using the modified Barthel Index (mBI).

Main Results:

  • Spasticity was present in 27% (MAS) and 36% (TAS) of patients.
  • Combined assessment revealed a spasticity prevalence of 38% (40 patients).
  • Patients with spasticity demonstrated significantly lower functional ability (mBI scores, p < 0.0001).

Conclusions:

  • Comprehensive assessment of both upper and lower limbs using both MAS and TAS is essential for accurate spasticity prevalence.
  • The observed prevalence of 38% is lower than some previous estimates, highlighting the importance of assessment methodology.
