Objective
To examine the short-term and long-term effects of computer-based cognitive training on postural stability, locomotion, and cognitive performance in Parkinson’s disease (PD) patients.
Methods
Sixty-eight PD participated in this randomized-controlled trial, were randomly allocated into two groups; control group (GA) received a designed physiotherapy program for 60 minutes, and an experimental group (GB) got 30 minutes physiotherapy program as GA, along with 30 minutes of computerized cognitive training. Treatment sessions were three times/week for eight weeks. Primary outcomes were balance and spatiotemporal gait parameters; cognition was a secondary outcome. Primary and secondary measures were examined at baseline, immediately post-treatment, and three months post-treatment.
Results
From baseline to post-treatment, GB showed greater reductions in postural sway compared to GA. The mean differences in stability indices were 1.461±1.240, 0.982±1.185, and 1.006±0.982 in GB, vs. 0.581±1.503, 0.426±1.459, and 0.374±1.072 in GA. For gait parameters (gait velocity, stride length, and cadence), GB demonstrated larger improvements, with mean differences of -0.361±0.245, -0.242±0.158, and -11.606±12.628, compared to -0.155±0.254, -0.191±0.248, and -4.516±10.773 in GA. PD-Cognitive Rating Scale improved more substantially in GB (-16.091±6.978) than in GA (-1.129±4.552). These gains in postural stability, gait, and cognition were statistically significant (p<0.001) and sustained at the 3-month follow-up.
Conclusion
Computerized cognitive training as an add-on in the rehabilitation of PD is efficient in improving postural stability and locomotion, as well as the cognitive performance. The consistency of these findings for 3 months is an imperative point in the clinical course of PD patients.
