reported the effect of exercise on pain in PD were identified, though pain was not the focus of the intervention in either trial. One reported a trend towards a reduction in pain, and the other reported a reduction in the presence and intensity of pain following exercise. However, these results do not indicate if exercise targets particular subtypes of pain.
Conclusion(s):The neurophysiological effects of exercise such as neuroplasticity, neuro-restoration and activation of dopaminergic and non-dopaminergic pain inhibition provide a sound biological rationale for employing exercise in pain management. However, randomised controlled trials of exercise interventions for people with PD are required to determine if exercise results in a clinical reduction in pain in this population.Implications: Therapists should consider assessing people with PD for pain and monitoring any changes in pain in response to exercise interventions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
