Summary

Most stroke survivors regain motor function within six months, especially those with mild to moderate initial deficits. Stroke severity significantly impacts recovery, while age and sex do not.

Area of Science:

  • Neurology
  • Rehabilitation Medicine
  • Public Health

Background:

  • Stroke is a leading cause of long-term disability, impacting motor function.
  • Understanding the natural history of motor function recovery is crucial for patient outcomes and healthcare planning.
  • Community-based studies provide valuable insights into real-world stroke recovery patterns.

Purpose of the Study:

  • To describe the natural history of motor function recovery after stroke.
  • To identify factors influencing motor recovery in a community-based cohort.
  • To assess the long-term functional outcomes for stroke survivors.

Main Methods:

  • A 1-year community-based prospective study in Auckland, New Zealand.
  • Inclusion of 680 patients presenting with stroke.
  • Assessment of motor deficits (hemiparesis) at onset and over a 1-year follow-up period.

Main Results:

  • 88% of patients presented with hemiparesis.
  • The proportion of survivors with persistent motor deficits decreased from onset to 71% at 1 month and 62% at 6 months.
  • 76% of 6-month survivors had no or mild motor deficits; recovery was strongly associated with initial stroke severity (mild deficit patients were 10x more likely to recover than severe).

Conclusions:

  • Stroke survivors generally have an optimistic outlook for motor function recovery.
  • Recovery is primarily linked to the initial severity of the motor deficit.
  • Significant motor function recovery is largely confined to patients with mild to moderate deficits at stroke onset.
