Effect of Adding Computerized Cognitive Training on Balance, Locomotion and Cognition in Parkinson's Disease

Study design: A randomized control clinical trial among sixty-eight Egyptian Parkinson's Disease patients of both sexes participated in the study; their ages ranged from 55 to 70 years. They were selected from the Neurology Clinics and from the Movement Disorder Clinic, Neurology Department, Faculty of Medicine, Cairo University, in the period from May 2024 to March 2025. The patients will be divided into two equal groups: the control group (GA) and the study group (GB). Patients in GA will be treated by a designed physiotherapy program consisting of aerobic exercise on a treadmill, stretching exercises, proprioceptive neuromuscular facilitation (PNF) techniques, graduated active exercises, gait training, reciprocal, and weight-shifting exercises for 60 minutes. Patients in (GB) will be treated with computer-based cognitive training using REHACOM (30 minutes) in addition to the same physiotherapy program as GA (30 minutes). Rehacom software will be used for cognitive training targeting four main cognitive domains; attention/concentration, figural memory, auditory response control, and visual response control. . The treatment session for all patients in both groups will be 60minutes/session. The whole treatment protocol will include 24 sessions, three sessions per week, for two successive months. Primary Outcomes: 1. Postural stability: \- Biodex balance system was used to assess dynamic balance indices ( Overall stability index, mediolateral stability \& anteroposterior stability) 2. Spatio-temporal gait parameters: * Digital video camera and kinovea (video motion analysis software) was used to assess spatiotemporal gait parameters (Stride length, velocity \& Cadence). Secondary Outcome: a. Overall cognitive functions: \- Parkinson's Disease - Cognitive Rating Scale (PD-CRS).
