The Impact of Physical Activity on Parkinson Disease Progression
Research has also shown that patients with Parkinson disease who are able to engage in physical activity can potentially improve the motor and non-motor symptoms associated with the disease.
Parkinson disease (PD) is a chronic neurodegenerative disorder that presents clinical symptoms that include the loss of motor and non-motor skills.1 Although the sole cause of this condition remains unknown, certain risk factors for PD have been identified, such as heredity, drugs, and environmental toxins.2
PD progresses gradually over time as symptoms continue to worsen until there is eventually a severe loss of motor and non-motor function. The loss of physical activity that results during disease progression has a profound impact on patients’ lives, as physical activity provides numerable benefits to health and wellness.3
Research has also shown that patients with PD who are able to engage in physical activity are potentially able to improve the motor and non-motor symptoms associated with the disease. Specifically, physical activity has been found to improve mobility, postural control, and gait.
For patients with PD, aerobic exercises have been observed to improve walking ability and balance,4 whereas treadmill exercises, stretching, and resistance exercises can also produce improved motor symptoms.5
Non-motor symptoms benefit from physical activity as well. Research suggests that regular multimodal physical exercises can reduce sleep disturbances,6 with the potential for improvement in cognition, which in turn can ameliorate depression and fatigue.4
Physical activity has also been found to potentially benefit patients with PD, as it reduces pain by activating pain inhibitor pathways and contributes to neurorestoration and neuroplasticity.5
The possibility of neuroprotection may account for the reduced risk of incidence of PD in persons who engage regularly in physical activity.4 Living a sedentary life can increase the risk of many diseases, including heart disease, stroke, and PD.3
The impact of physical activity on the progression of PD has been assessed by researchers both based on the type of exercise and the consistency. In some studies, the effects of physical activity were assessed based on specific exercises, whereas in others, the results were recorded based on the regularity of the physical activity.
Ultimately, although patients with PD are more likely to be sedentary due to the motor symptoms associated with the disease, prescribing appropriate exercises and supporting consistent adherence to the activities can help to improve the condition and overall quality of life for the patient.7
