Impact of a Dynamic Orthosis on Manual Dexterity in Parkinson’s Disease
Importance of the Study
A dynamic elastomeric fabric orthosis may offer a new non-drug treatment for motor symptoms in people with Parkinson’s disease (PD).
Study Objective
The goal was to assess how effective the orthosis is in improving manual dexterity in individuals with PD.
Study Design
This was a randomized trial with 60 participants divided into two groups: a control group (20 participants) and an experimental group (40 participants). Manual dexterity was evaluated during different states of the disease, both with and without the orthosis.
Setting and Participants
The trial took place at Burgos University Hospital in Spain. Participants were selected based on specific criteria, including a PD diagnosis and motor symptoms in at least one upper limb. Ages ranged from 48 to 89 years, with an average disease duration of over 5 years.
Intervention
The experimental group wore the orthosis on their most affected upper limb for two months, while the control group did not use the orthosis.
Outcomes Measured
Manual dexterity was assessed using various tests, and statistical analyses were conducted to evaluate the results.
Results
Some participants showed improvement in manual dexterity while wearing the orthosis, but these gains were not maintained after removal of the device.
Conclusions and Relevance
The orthosis may enhance certain manual dexterity skills and overall functionality in people with PD, but benefits are temporary and only occur while wearing it. Improving manual dexterity is crucial for maintaining independence and quality of life in individuals with PD.
Summary
This study indicates that while wearing the orthosis, motor symptoms of PD were alleviated, and manual dexterity improved, potentially leading to greater autonomy and enhanced quality of life.
