Summary

This pilot study aims to investigate the effects of 8-week SMARTfit training versus conventional physical training on motor function, cognition and brain functional connectivity in individuals with PD. The investigators hypothesize that clinical and physical performance will improve after SMARTfit training more than after conventional physical training.

Detailed description

Although Parkinson's disease (PD) has been mainly viewed as a movement disorder, the pathophysiology of declined motor function incorporates impairments of multiple systems, including sensory, motor and cognitive pathways. Specifically, it has been demonstrated that cognitive function may play an essential role in motor function for individuals with PD. Cognitive dysfunction involving set-shifting and attentional control has been found to be associated with movement slowness in performing a finger sequence task and freezing of gait. Furthermore, a recent rodent model indicates that cognitive dysfunction may occur prior to the onset of motor symptoms. Similarly human studies show that 25-30% individuals with PD exhibit cognitive impairments at the time of diagnosis. The overall evidence suggests that cognitive dysfunction may contribute to degraded motor function in PD. Interestingly, several studies demonstrate that aerobic exercise and resistance training can improve cognitive function in individuals with PD, indicating a tight interplay between motor and cognitive function. Targeting cognitive function by incorporating cognitive training into physical rehabilitation may be important for people with PD. Although there is mounting evidence for the benefits of physical exercise in PD, few studies investigate whether combining cognitive training with physical exercise can provide additional benefits than physical exercise alone. Thus, the purpose of this pilot study is to investigate the effect of SMARTfit training, a novel technology that provides an opportunity to combine physical training with cognitive training, in individuals with PD. The hypothesis is that SMARTfit training will promote greater motor and cognition improvements than conventional physical training. To test the above hypothesis, ten individuals with mild PD will receive both SMARTfit training and conventional physical training in a counterbalanced order with a washout period. For each training program, participants will receive a 1-hour training session 3 times per week for 8 weeks. The changes in disease biomarkers before and after training will also be explored.

Interventions

Type	Name	Description
BEHAVIORAL	SMARTfit training	For SMARTfit training, participants receive three 1-hour training sessions per week for 8 weeks. During each week, participants will receive physical training focused on six tasks, which are the functional tasks individuals with PD commonly have difficulty with. The six tasks are paired into 3 pairs: (1) sit-to-stand and multi-plane locomotor tasks, (2) gait and reach \& grasp, and (3) floor-to-stand; stand-to-floor and single limb standing. Participants will focus on practicing one pair of tasks during each session. There is an additional cognition component that can be manipulated using features provided by SMARTfit.
BEHAVIORAL	Conventional physical training	For conventional physical training, participants receive three 1-hour training sessions per week for 8 weeks. During each week, participants will receive physical training focused on six tasks, which are the functional tasks individuals with PD commonly have difficulty with.
