Exercise capacity is significantly reduced in patients within one month after a stroke. This study highlights the compromised physical function in early post-stroke recovery, indicating a need for further investigation into underlying physiological factors.

Area of Science:

  • Cardiology
  • Neurology
  • Rehabilitation Medicine

Background:

  • Stroke survivors often experience reduced physical function.
  • Early assessment of exercise capacity is crucial for rehabilitation planning.

Purpose of the Study:

  • To evaluate the exercise capacity of patients in the early phase after stroke (less than 1 month).

Main Methods:

  • Prospective, observational cohort study involving 29 patients.
  • Exercise capacity measured as peak oxygen consumption (VO2peak) using spirometry.
  • Maximal effort treadmill testing with 15% body-weight support was employed.

Main Results:

  • Mean VO2peak was 14.4±5.1 mL·kg−1·min−1.
  • This represents approximately 60%±16% of age- and sex-matched normative values for sedentary adults.

  • Early post-stroke exercise capacity was found to be significantly compromised.

    • Conclusions:

    • Patients exhibit substantially reduced exercise capacity approximately one month after stroke.
    • The physiological underpinnings of this diminished capacity require further research.
    • Findings suggest potential for targeted interventions to improve early post-stroke physical function.
