Deans' stroke musings: Development of a wrist and hand stretching device for managing spasticity in stroke patients: a pilot study

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Objectives: We developed a straightforward stretching device for the wrist and hand. To assess the device’s effectiveness in managing spasticity among chronic stroke patients.

Methods: The device, primarily constructed from plastic, comprises a forearm support module, a wrist module, and a finger module. Twenty stroke patients used the device four times daily, 7 days a week, for 1 month. Spasticity severity was measured using the Modified Ashworth Scale (MAS) for the wrist, thumb, and index fingers. A questionnaire evaluated the device’s feasibility and areas for improvement.

Results: Before treatment, the mean MAS scores for the wrist, thumb, and index finger flexors were 1.50 ± 0.36, 1.52 ± 0.34, and 1.50 ± 0.30, respectively, compared with 1.25 ± 0.26, 1.27 ± 0.30, and 1.32 ± 0.33 post-intervention. Patients and occupational therapists expressed satisfaction with the device, citing its ease of use, effectiveness in stretching the wrist and fingers, and overall ease of manipulation. Half of the patients reported that all fingers were easily extended. The rigid plastic finger module was subsequently replaced with an inflatable, flexible rubber ball, providing a more comfortable contour for the stretched fingers, which increased user satisfaction.

Conclusion: The stretching device effectively reduced spasticity in the wrist and hand, and the upgraded device enhanced patient satisfaction.
