Dynamic-orthosis Programs for Stroke Hand Function

Development of Innovative Modular 3D-Printed Dynamic Orthoses: Application Programs for Hand Function Facilitation in Patients With Stroke

This study aims to investigate the training benefits of modular 3D printed dynamic orthoses on upper limb function in stroke survivors.

This study is a randomized controlled intervention trial. Participants are recruited from two medical centers in Taiwan and undergo a continuous 6-week intervention for post-stroke movement rehabilitation. The control group receives traditional stroke occupational therapy rehabilitation. The experimental group, in addition to traditional treatment, supplements their therapy with the use of modular 3D printed dynamic orthoses developed by the research team for home training. Both groups undergo two effectiveness follow-up assessments, one month and two months after the intervention.

Inclusion criteria:

1. Onset of stroke at least three months ago;
2. Upper limb Brunnstrom stage II~IV;
3. Shoulder can actively flex at least 45 degrees.

Exclusion criteria:

1. Affected hand has regained autonomous grasping function, able to grasp and release a tennis ball 10 times within 2 minutes;
2. Joint deformity or stiffness in the affected hand that prevents the use of the dynamic orthosis;
3. Diagnosis of other neurological disorders affecting motor control, such as neglect, Parkinson's disease, etc.;
4. Inability to follow therapist guidance;
5. Currently undergoing other specific treatments affecting motor function recovery (such as rTMS and BTX).
