Study summary

The goal of this study is to determine the effectiveness of behavioral support and feedback from a wearable device that senses arm movement in improving upper extremity function in a pilot, randomized controlled trial with chronic stroke patients

Read the detailed description

In this randomized controlled trial, the investigators will evaluate two telerehabilitation strategies for increasing arm use at home: a smartwatch app and a psychological intervention. The psychological intervention aims to address ambivalence and enhance motivation, while the smartwatch provides feedback on arm movement variability. The investigators hypothesize that combining the psychological intervention with smartwatch feedback will lead to greater improvements in arm use and upper extremity recovery

Study arms

  • Experimental
    Movement Variability

    The movement variability group will have a smartwatch app that records movement variability. Their movement goal will be centered on increasing their total movement variability as measured by the watch.

    Other: Smartwatch App for Movement Variability · Behavioral: Motivational Interviewing (Within Subjects)

  • Placebo comparator
    Active Time (Control)

    This group will only receive active-time feedback (the number of minutes and hours moving the upper extremity). Their goal will focus on increasing their total movement time.

    Other: Smartwatch App for Active Time · Behavioral: Motivational Interviewing (Within Subjects)

Interventions

  • OtherSmartwatch App for Movement Variability

    This app measures movement variability in the upper extremity as described in our previous study (doi:10.3390/s24165266).

  • OtherSmartwatch App for Active Time

    The other software we are using measures total active time of the upper extremity.

  • BehavioralMotivational Interviewing (Within Subjects)

    Motivational Interviewing is an established therapeutic technique designed to increase patient adherence to therapy by addressing ambivalence. The motivational Interviewing sessions will include a variety of techniques such as: Open ended questions, Active Listening, Affirmation, Summarization, Questions focused on change talk, and Providing Information.

What researchers measure

Primary outcomes

  1. Variability Measurement

    The amount of variability for the impaired upper extremity will be quantified by the variety of movements performed.

    Time frame: From enrollment to the end of treatment and follow up measurement (9 weeks)

Secondary outcomes

  1. Active Time

    This outcome measures the active time of the impaired upper extremity in minutes and hours.

    Time frame: From enrollment to the end of treatment and follow up measurement (9 weeks)

  2. Fugl-Meyer Arm Motor Assessment

    The Fugl-Meyer Arm Motor Assessment measures motor impairment, movement coordination, reflexes, and functional ability of the upper limb in stroke patients, providing a quantitative evaluation of motor recovery based on a standardized scoring system.

    Time frame: Initial Visit, First follow up, Second follow up

  3. Box and Blocks Test

    The Box and Blocks Test (BBT) measures manual dexterity, unilateral gross motor function, and upper limb coordination in stroke patients by assessing the number of blocks transferred within a set time, providing an objective indicator of motor recovery and functional hand use.

    Time frame: Initial Visit, First follow up, second follow up

  4. Nine Hole Peg Test

    The 9-Hole Peg Test (9HPT) measures fine motor coordination, dexterity, and finger-hand function by assessing the speed at which a participant can place and remove pegs from a board.

    Time frame: Initial Visit, First follow up, Second follow up

  5. Motor Activity Log (MAL)

    The Motor Activity Log (MAL) measures the amount and quality of spontaneous arm use in daily activities in stroke patients with hemiparesis, using patient-reported ratings on a structured questionnaire to assess real-world upper limb function.

    Time frame: Initial Visit, First follow up, Second follow up

  6. Open Point

    Open Point measures proprioception in patients with impaired upper extremity function due to stroke. Cornella-Barba, G., Farrens, A. J., Johnson, C. A., Garcia-Fernandez, L., Chan, V., \& Reinkensmeyer, D. J. (2024). Using a Webcam to Assess Upper Extremity Proprioception: Experimental Validation and Application to Persons Post Stroke.

  3. Modified Ashworth Spasticity Scale

    The Modified Ashworth Spasticity Scale measures muscle spasticity by assessing resistance to passive movement in a limb, grading it on a scale from 0 (no increase in tone) to 4 (rigid in flexion or extension).
