Deans' stroke musings: Inter-Rater Reliability of the Chedoke Arm and Hand Activity Inventory in an Acquired Brain Injury Population

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.

Inter-Rater Reliability of the Chedoke Arm and Hand Activity Inventory in an Acquired Brain Injury Population

You can check out the CAHAI here and see how subjective it is contrary to what the research here implies. Needing research on inter-rater reliability already means that the measurement used is wrong. You really need to start doing objective scans of brain damage and maybe then we could finally precisely map stroke protocols to damage rather than these crappy subjective measurements.

Abstract:	Background: Motor impairments are common sequelae of Acquired Brain Injuries (ABI). An estimated 55-75% of ABI survivors have on-going limitations in UL function. Objective measures of UL function that have established validity and reliability in the ABI population are not readily available in the literature. The Chedoke Arm and Hand Inventory (CAHAI) is an assessment used with the stroke population. There are 4 versions of this assessment; a 13 item version and 3 shortened ones. The main purpose is to assess how much the affected UL contributes to a bilateral task. The CAHAI has strong reliability and validity in this population; however, it is unknown whether this measure can be used with other clinical populations such as ABI. Purpose: The purpose of this study was to estimate the inter-rater reliability of the Chedoke Arm and Hand Activity Inventory (CAHAI) when used with persons with ABI including 3 shortened versions of the measure. Methods: This is an observational parameter estimation study. Participants were recruited from an in-patient ABI rehabilitation program. The administration of the CAHAI was video recorded for 6 persons with ABI. The videos were assessed by 6 clinicians to estimate inter-rater reliability. A Latin square design was used to balance the order raters evaluated the videos. Analysis: A repeated measures ANOVA was performed and the variance components were used to calculate an intra-class correlation coefficient (ICC) and standard error of measurement (SEM) with 95% confidence intervals (CI). Results: Inter-rater reliability was high for all versions: CAHAI-7 ICC= 0.96 (95% CL: 0.89-0.99, SEM 2.65); CAHAI-8 ICC= 0.96 (95% CL: 0.90-0.99, SEM 2.72); CAHAI-9 ICC= 0.95 (95% CL: 0.85-0.99, SEM 3.49); CAHAI -13 ICC=0.96 (95%CL: 0.88-0.99, SEM 3.35). Conclusions: These results suggest the CAHAI is highly reliability in the ABI population. The shortened versions may be particularly useful when time constraints or patient tolerance are an issue.
