Deans' stroke musings: Responsiveness of Upper Extremity Kinematic Measures and Clinical Improvement During the First Three Months After Stroke

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.

Responsiveness of Upper Extremity Kinematic Measures and Clinical Improvement During the First Three Months After Stroke

I love this, they tested a drinking task. Ask your doctor to follow up what it was,dark beer or wine? Its damn important to know those details.
I might have recovered my bad arm/hand by now if I had been challenged with this drinking game.

Abstract

Background. Kinematic movement analysis is increasingly used as an outcome measure in evaluation of upper extremity function after stroke. Little is known, however, about what observed longitudinal changes in kinematics mean in the context of an individual’s functioning. In this study, the responsiveness and expected change in kinematic measures associated with clinically meaningful improvement in the upper extremity were evaluated. Methods. Kinematic movement analysis of a drinking task and Action Research Arm Test (ARAT) were performed early (9 days poststroke) and at 3 months after stroke in 51 subjects. The receiver-operating characteristic curve and linear regression analyses were used to evaluate responsiveness of kinematic parameters. Results. Movement time, smoothness, and trunk displacement discriminated those subjects demonstrating clinically meaningful improvements. Significant associations of 31% to 36% were found between the change in ARAT and kinematic measures. A real clinical improvement in kinematics lies in the range of 2.5 to 5 seconds, 3 to 7 units, and 2 to 5 cm in movement time, smoothness, and trunk displacement, respectively. Conclusions. All kinematic measures reported in this study are responsive measures for capturing improvements in the upper extremity during the first 3 months after stroke. Approximate estimates for the expected change in kinematics associated with clinically meaningful improvement in upper extremity activity capacity illustrate the usefulness of the linear regression analysis for assessing responsiveness. This knowledge facilitates the selection of kinematic measures for clinical and movement analysis research as well as for technology-based devices.
