Overview

Randomized trial investigates balance control in Parkinson's patients, older and younger adults, highlighting neural differences.

Key Points

  • This study aims to explore the neural mechanisms underlying balance control in individuals with Parkinson's disease, older adults, and younger adults.
  • Conducted four 2-minute standing conditions with 80 people with Parkinson's disease, 33 older adults, and 38 younger adults.
  • Utilized fNIRS to measure changes in relative oxygenated haemoglobin across various cortical areas.
  • Assessed sway outcomes using six wearable sensors to record measures such as area and velocity.
  • People with Parkinson's disease exhibited significantly increased sway outcomes compared to other groups.
  • Increased oxygenated haemoglobin in the prefrontal cortex was observed in individuals with Parkinson's compared to older adults.
  • Younger adults showed a greater increase in oxygenated haemoglobin in the somatosensory cortex when compared to older adults and those with Parkinson's.
