Exergaming-Based Dexterity Training in Persons With Parkinson Disease: A Pilot Feasibility Study

Area of Science:

• Neurorehabilitation
• Human-Computer Interaction
• Movement Science

Background:

• Parkinson disease (PD) frequently causes impaired dexterity, affecting daily living and quality of life.
• Exergaming, utilizing augmented virtual reality, presents a potential therapeutic approach for functional improvement in PD patients.
• This pilot study aimed to assess the feasibility of an exergaming-based dexterity training program for individuals with PD.

Purpose of the Study:

• Evaluate the feasibility of exergaming for dexterity training in Parkinson disease.
• Assess adherence, participation, and usability of the exergaming system.
• Explore potential improvements in dexterous function and quality of life.

Main Methods:

• Ten participants with PD (Hoehn and Yahr stages II-IV) underwent a 4-week exergaming program (2x/week, 30 min).
• Feasibility was measured by adherence rate, motivation (Pittsburgh Rehabilitation Participation Scale), and usability (System Usability Scale).
• Dexterity was assessed using the Nine-Hole Peg Test and Dexterity Questionnaire-24; motor impairment by MDS-UPDRS III; quality of life by PDQ-39.

Main Results:

• High adherence (99%) and significantly increased motivation (3.9 to 4.8, P=0.03) were observed.
• The exergaming system demonstrated acceptable to very good usability.
• Participants showed significant improvements in the Nine-Hole Peg Test and PDQ-39 scores.

Conclusions:

• Exergaming is a feasible intervention for individuals with Parkinson disease.
• The study suggests exergaming has potential to enhance dexterity in PD.
• Further investigation in a randomized controlled trial is recommended to confirm efficacy.
