About this study
Official title: Feasibility Study on Portable Rehabilitation (PoRi) Device in Hand Spasticity
This study is a feasibility study of a new device that moves the hand of patients with spasticity to reduce hand muscle tone. The device's ability to improve spasticity before and after a 20-minute session with the device at Yale New Haven Hospital's outpatient clinic of Physical Medicine \& Rehabilitation, or the Inpatient Rehabilitation Unit.
Read the detailed description
Each patient will participate in a single 20 minute session, during which the device will extend and flex finger muscles. Each participant's duration will be approximately 1 hour during clinic, including time to address any further questions, to calibrate the device, and to measure the Modified Ashworth Score (MAS) before and after the intervention.
- Conditions
- Hand Spasticity
- Being tested
- Portable Rehabilitation (PoRi) device
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.

Once the calibration is complete, the device moves the fingers to close and open the hand for a total of 20 minutes.

| Hand Spasticity | Experimental | Each participant will have a single 20 minute session, during which the device will extend and flex finger muscles. Each participant's duration will be approximately 1 hour during clinic, including time to address any further questions, to calibrate the device, and data collection. Receives: Device: Portable Rehabilitation (PoRi) device |
What is being measured
The primary outcome is the main question the study is designed to answer.
Feasibility assessed using the change in Modified Ashworth Scale (MAS) score
Muscle tone is rated on a 6-point scale (0, 1, 1+, 2, 3, 4) with higher scores indicating greater spasticity.
Measured: immediately prior to intervention session and immediately following 20 minute intervention session
Secondary outcomes (1)
Device usability and accessibility survey
Device usability and accessibility will be evaluated through a patient and researcher survey.
Measured: immediately following 20 minute intervention session

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 19 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Feasibility assessed using the change in Modified Ashworth Scale (MAS) score (time frame: immediately prior to intervention session and immediately following 20 minute intervention session). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Dec 2025; AzTrials last refreshed its copy on 27 Oct 2026.
