NCT07271927

Brief Summary

This study aims to exploratorily evaluate the extent of motor and cognitive changes, as well as the safety, resulting from approximately 10 weeks of whole-body photobiomodulation (PBM) therapy (about three sessions per week, once daily, 20 minutes per session) in patients with Parkinson's disease.

Outcome Measures

Primary Outcomes (1)

  • UPDRS

    Unified Parkinson's Disease Rating Scale

    Change in UPDRS from baseline to post 30 sessions (up to approximately 10 weeks). The UPDRS ranges from 0 to 199, with higher scores indicating greater symptom severity.

Secondary Outcomes (10)

  • BBS

    Change in Berg Balance Scale scores from baseline to post 30 sessions (up to approximately 10 weeks). The BBS ranges from 0 to 56, with higher scores indicating better balance performance.

  • Grip strength and pinch strength test

    Change in Grip strength and pinch strength from baseline to post 30 sessions (up to approximately 10 weeks). Higher scores indicate better hand function.

  • FRT

    Change in Functional Reach Test scores from baseline to post 30 sessions (up to approximately 10 weeks). Higher scores indicate better hand function.

  • TUG

    Change in Timed Up and Go test scores from baseline to post 30 sessions (up to approximately 10 weeks). Lower scores indicate better functional mobility.

  • CTRS

    Change in CRTS scores from baseline to post 30 sessions (up to approximately 10 weeks). The score ranges from 0 to 160, with higher scores indicating more severe tremor symptoms.

  • +5 more secondary outcomes

Study Arms (1)

Parkinson

EXPERIMENTAL

Participants received whole-body PBM therapy once daily (20 minutes per session), three times per week, for approximately 10 weeks, totaling 30 sessions.

Device: Photobiomodulation

Interventions

Participants received whole-body PBM therapy over approximately 10 weeks (three sessions per week, once daily, 20 minutes per session), with each session using a randomly selected wavelength of either 660 nm, 850 nm, or 940 nm (±20%).
