Group tele-rehabilitation improves quality of life among subjects with Parkinson's disease: A two arm non-parallel non-randomized clinical trial.

Introduction: Tele-rehabilitation has lately emerged as a promising medium for increasing patient adherence with significant positive results. One of the most prevalent neurological diseases affecting movement is Parkinson's disease (PD), which causes a variety of motor and non-motor symptoms among patients. Consequentially, the study was designed to compare the efficacy of group tele-rehabilitation with individual tele-rehabilitation in improving quality of life (QoL) among subjects with PD.

Method: A two-group pretest-posttest, non-randomized clinical study recruited 68 subjects and classified them into two groups, i.e., Group A (group therapy, n = 36) and Group B (individual therapy, n = 32). Groups A and B received a supervised protocol consisting of a 40-min session on alternate days/week for twelve weeks via the WhatsApp Messenger application through group and individual therapy, respectively. The Parkinson's disease questionnaire (PDQ-39), mental and physical components of the Short Form Survey (SF-12) were used as primary outcome variables, while the Satisfaction questionnaire was used as a secondary outcome variable.

Result: The p-values related to within-group analyses were <0.05 except SF-12 PCS >0.05 in Group A and <0.05 in Group B. While the p-values related to between-group analyses were <0.05 except for pre-scores of SF-12 (MCS and PCS). The effect sizes for PDQ-39, SF-12 (MCS), and SF-12 (PCS) were -2.37, 3.36, and 0.66 in Group A and 1.95, 2.69, and 2.03 in Group B, respectively.

Conclusion: The study concluded that group tele-rehabilitation is more effective in improving QoL among subjects with PD as compared to individual tele-rehabilitation. Clinical trial Registration NoCTRI/2022/04/041818.
