KPE research published in Journal of Neurology, Neurosurgery and Psychiatry

Last fall, Chad Lebold became the first graduate of Laurier’s master’s of science program in kinesiology and physical education (KPE).

This fall, the Journal of Neurology, Neurosurgery and Psychiatry will publish a manuscript produced from his master’s thesis work, “Freezing of gait in Parkinson’s disease: a perceptual cause for a motor impairment.”

Lebold’s research was also featured on Medscape Neurology, a news and education site for clinicians and health professionals, and was rated No. 5 by NeurologyLinx, an online index of articles for physicians and health-care professionals.  

Lebold, who is a lab instructor for several KPE courses, conducted his research with Dr. Quincy Almeida, associate KPE professor and director of the Sun Life Financial Movement Disorders Research and Rehabilitation Centre (MDRC).

“I congratulate Chad on this wonderful achievement,” says Almeida. “His article was expedited for publishing online in the journal in mid-September and achieved this elite status in just a week.”

Almeida and Lebold designed experiments to examine the gait of subjects approaching doors of varying widths to determine the underlying causes of motor freezing episodes experienced by some Parkinson’s disease patients.

Their results challenge current beliefs that freezing is a motor impairment, instead suggesting that patients are having problems with space perception because of sensory-perceptual issues that interfere with movement.

“It is important to think outside the box (and to) question what the underlying mechanism for clinical motor impairments might be,” Almeida told Medscape Neurology. “Probably the most surprising finding is that even Parkinson’s patients who do not have issues with freezing can be profoundly influenced by the perception of an upcoming narrow doorway.”

The article will be published in the journal by the end of October, and is one of three manuscripts produced from Lebold’s thesis work. To read the article online, visit
