This study developed a haptic device for stroke patient finger rehabilitation. The device demonstrated improved progress in affected hands, though non-affected hands showed higher baseline function.

Area of Science:

  • Rehabilitation Engineering
  • Haptic Technology
  • Neurorehabilitation

Background:

  • Stroke often impairs hand function, necessitating effective rehabilitation tools.
  • Haptic devices offer promising avenues for targeted motor skill recovery.
  • Existing rehabilitation methods may lack precise force feedback and engagement.

Purpose of the Study:

  • To design, construct, and test a novel haptic device for finger exercise in stroke patients.
  • To evaluate the efficacy of the haptic device in a clinical setting over a one-month therapy period.
  • To compare the device's impact on affected versus non-affected hand function and relate it to clinical scales.

Main Methods:

  • Development of a two-active-degree-of-freedom, tendon-driven haptic device with a 10 N force capacity.

  • Implementation of a control loop and user application on a personal computer (Windows environment).
  • Clinical evaluation with stroke patients over one month, assessing two experiment types and comparing results to the motor component of the Functional Independence Measure (M-FIM).

    • Main Results:

    • The haptic device system was successfully constructed and tested.
    • Patients showed greater progress in their affected hand function during the therapy period.
    • Higher mean values for relevant parameters were observed in the non-affected hand compared to the affected hand.

    Conclusions:

    • The developed haptic device is suitable for finger exercise and shows potential in stroke rehabilitation.
    • The device facilitated greater functional improvement in the affected hand compared to the non-affected hand.
    • Results suggest the haptic device can be a valuable adjunct to traditional therapy, with further investigation warranted.
