Summary

Continuous passive motion (CPM) may improve shoulder stability in stroke patients. Device-delivered CPM showed positive trends for reducing adverse symptoms in the hemiplegic arm compared to self-range of motion exercises.

Area of Science:

  • Neurology
  • Rehabilitation Medicine
  • Biomedical Engineering

Background:

  • Stroke frequently causes hemiparesis, leading to upper limb motor deficits and adverse symptoms like shoulder instability, pain, and increased tone.
  • Managing these symptoms is crucial for functional recovery and improving the quality of life for stroke survivors.

Purpose of the Study:

  • To investigate the efficacy of device-delivered continuous passive motion (CPM) in treating upper limb impairment, disability, and adverse symptoms in patients with a first stroke and hemiparesis.
  • To compare CPM treatment with supervised self-range of motion exercises in a pilot study.

Main Methods:

  • A randomized pilot study involving 35 patients with a first unilateral stroke, 13 days post-event.
  • Patients received either daily device-delivered CPM or supervised self-range of motion exercises, alongside standard post-stroke therapy.

  • Outcomes were assessed by a blinded evaluator using standardized scales for motor impairment, disability, and adverse shoulder symptoms (stability, pain, tone).

    • Main Results:

    • CPM-treated patients showed a positive trend towards improved shoulder joint stability compared to the self-range of motion group (p = 0.06).
    • No significant differences were observed between groups in motor impairment, overall disability, pain, or muscle tone.

    Conclusions:

    • Device-delivered continuous passive motion (CPM) may offer potential benefits for reducing specific adverse symptoms, such as shoulder instability, in the hemiplegic arm post-stroke.
    • CPM could be a valuable adjunct to traditional self-range of motion exercises in stroke rehabilitation, warranting further investigation.
