The influence of dynamic orthosis training on upper extremity function after stroke: a pilot study

Area of Science:

• Neurorehabilitation
• Biomechanics
• Physical Therapy

Background:

• Stroke survivors often experience chronic upper extremity hemiparesis, limiting functional independence.
• Task-oriented training is a key approach for motor recovery, but may require assistive devices.
• Dynamic orthoses offer potential to support and enhance functional movements.

Purpose of the Study:

• To evaluate the efficacy of a dynamic orthosis in improving upper extremity function.
• To assess the impact of a structured training program combined with a dynamic orthosis.
• To investigate functional capacity changes in chronic stroke patients with hemiparesis.

Main Methods:

• A case series design was employed with six chronic stroke volunteers.
• Participants underwent an 8-week training program (3x/week, 50 min/session) using a dynamic orthosis.
• The Test d'Évaluation des Membres Supérieurs de Personnes Âgées (TEMPA) assessed functional capacity before and after training.

Main Results:

• Significant improvements were observed in upper extremity function for a bilateral task (p = 0.01).
• Significant improvements were also noted in three unilateral tasks (p = 0.04).
• The TEMPA scores indicated enhanced functional capacity post-intervention.

Conclusions:

• Dynamic orthosis use, coupled with task-oriented training, shows promise for improving upper extremity function in chronic stroke.
• This pilot study suggests a positive outcome for functional capacity enhancement.
• Further research with larger cohorts is warranted to confirm these findings.
