Deans' stroke musings: Rasch analysis of the activities-specific balance confidence scale in individuals poststroke.

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.

Rasch analysis of the activities-specific balance confidence scale in individuals poststroke.

Nothing on how to ensure balance in stroke survivors, so USELESS.

Abstract:

Study examined the psychometric properties of the Activities-specific Balance Confidence (ABC) scale using Rasch analysis for stroke survivors. Data was extracted from the Locomotor Experience Applied Post-Stroke phase-3, multisite, randomized controlled clinical trial for 406 community-dwelling, ambulatory, older adults who were approximately 2 months post stroke. Outcome measures examined unidimensionality, local dependence, rating-scale structure, item and person fit, person-item match, and separation index of the ABC scale. Confirmatory and exploratory factor analysis showed the ABC scale was adequately unidimensional and 3-item pairs had local dependence. A collapsed 5-category rating scale was superior to the 101-category scale. The hardest item was “walking outside on an icy sidewalk,” the easiest item was “getting into or out of a car,” and no items misfit. The ABC scale had high person reliability (0.93), despite 10.5 percent of individuals misfitting the expected response pattern. Mean ability level of the sample was slightly lower (−0.56 logits) than the mean item difficulty indicating that the ABC scale adequately matched our sample’s balance confidence. The ABC scale did not have a floor or ceiling effect and separated individuals into 5 statistically distinct strata (separation index = 3.71). The Rasch model supports the use of the ABC scale to measure balance confidence in individuals poststroke. Recommendations include collapsing the rating scale and developing a computerized-adaptive test version of the scale to enhance clinical utility.
