Brief Summary

The hand is important to perform activities of daily living (ADL). However, many people experience a loss of hand function as result of a traumatic brain injury, spinal cord injury, stroke or orthopedic problems, or due to ageing. To improve hand function, or reduce its decline, one can benefit from exercise therapy or use of assistive aids to improve ADL independence. A promising innovative approach combining both is a wearable soft-robotic glove that supports hand grip. With this glove, performance of functional activities can be supported directly, while also facilitating repeated use of the affected arm and hand during functional daily activities. One of our previous studies showed that besides a direct support effect, a therapeutic effect on performance was found after several weeks of using the soft-robotic glove as support during ADL. However, several participants reported complaints of increased pain and/or overload, mainly at the beginning of the trial. Clinicians suspect that a (too) high intensity of hand use compared to normal is contributing to this observation. This might be related to more fatigue experienced when using the glove in high-demand tasks, due to a larger movement capacity (faster, further, more repetitions) and can be associated with decreased blood perfusion/lower saturation levels at muscular level and altered muscle activation and movement coordination. Therefore, the primary objective is to examine the effect of use of the assistive soft-robotic glove during strenuous ADL tasks on the kinematic movement profile, compared to not using the soft-robotic glove. Secondary objectives are to examine whether pain or discomfort is experienced in strenuous activities with the soft-robotic glove as well as the characteristics and locations of such pain/discomfort, and to examine whether use of the glove is associated with increased handgrip strength, larger number of ADL task repetitions, diminished blood perfusion / reduced tissue saturation at the muscle and/or changes in muscle activity.

Outcome Measures

Primary Outcomes (1)

  • Kinematic movement profile during performance of strenuous ADL task

    The kinematic movement profile during performance of strenuous ADL task, characterized by the following parameters as assessed using 3D marker-based motion capture: • Total movement duration * Duration of movement phases * Movement smoothness * Trunk displacement * Peak hand velocity * Time to peak velocity of reach phase * Hand opening * Joint excursion of the elbow * Joint excursion of the wrist * Endpoint straightness * Endpoint error

    1-2 hours during the measurement session

Secondary Outcomes (7)

  • Experienced pain/discomfort rating + description

    Twice during the measurement session, after completion of both conditions, with a duration of 5-10 minutes.

  • Perceived exertion and confidence in grip rating

    Twice during the measurement session, after completion of both conditions, with a duration of 5-10 minutes.

  • Maximal handgrip strength

    1-2 hours during the measurement session

  • Handgrip endurance

    1-2 hours during the measurement session

  • Number of repetitions achieved during ADL task

    1-2 hours during the measurement session

  • +2 more secondary outcomes

Other Outcomes (1)

  • Subject characteristics

    At the start of the measurement session, taking about 5 minutes

Study Arms (1)

Study group

OTHER

All participants in the study will perform arm/hand movement tasks in both of two conditions (with and without soft-robotic glove), so they constitute 1 study arm, but all receiving both intervention conditions (experimental - with glove and control - without glove).

Device: Soft robotic glove

Interventions

The soft-robotic glove used in the study is the Carbonhand system (Bioservo Technologies, Sweden). It is a CE-marked medical device and it consists of a glove that supports finger flexion via sewn-in tendons and a control unit housing the actuators that pull on the tendons and the batteries. The grip support is activated by applying very light pressure on sensors in the fingertips of the glove, and de-activated by releasing the pressure on the sensors.
