Applying these assumptions, a sample size of 50 people with stroke per group, or in total, were required. We recognized that the increased efficiency associated with the shorter measure would come at a cost to its validity, and we examined whether the cost in terms of validity would be too great and render the proposed shorter measure ineffective.

Citing articles via Google Scholar. With so many upper-limb measures available, it is natural to question the development of another measure.

Motor control and motor learning: Receiver operating characteristic curves, Pearson product moment coefficient of correlation, and regression analyses were used.

Spearman rank-order correlation coefficient and intraclass correlation coefficient have been used to demonstrate high levels of interrater reliability. When refering to evidence in academic writing, you should always try anx reference the primary original source. This study was conducted at 4 facilities in the vicinity of Hamilton, Ontario, Canada, that provided either inpatient or outpatient rehabilitation services. You must accept the terms and conditions.

Preference was given to items that reflected real-life bilateral functional activities and maximized the range of normative upper-limb movements and grasps.

Five clients within 14 days of stroke were recruited by consecutive sampling from chedoje metropolitan hospital and participated in structured individual interviews.

Careful consideration of the theoretical constructs underpinning the CAHAI has resulted in a tool that is consistent with the current frameworks of motor learning and performance. Copyright Thomas Land Publishers Activith www. The predictive equations for data obtained at the 2 assessment points were almost identical:. Accordingly, we split the difference.

Heart and Stroke Foundation of Ontario. For example, in a pair of patients who have both truly changed by different amounts, using a measure that has a curve area of 0. Uniform Data System for Medical Rehabilitation. I agree to the terms and conditions.

All therapists agreed CAHAI-9 was suited for the stroke population and assisted identification of client abilities or difficulties within functional ativity. There were 2 objectives to this study: Retrieved from ” https: It uses the Fisher z transformation, which converts the Pearson r to a normal distribution and, in this way, allows a comparison of 2 or more measures with a dependent variable eg, gains in upper-limb function.

A curve area of 0. The final measure consists of 13 items—hereafter referred to as the CAHAI—and takes approximately 25 minutes to administer and score. Nand addition, the CMSA was administered at the initial assessment, and the information was used to categorize participants for the longitudinal validity component of this investigation.

Written informed consent was obtained from each participant or his or her substitute decision maker. Mr Stratford provided data analysis. Close mobile search navigation Article navigation.

International Classification of Functioning, Disability and Health. The relationship for the follow-up scores not shown was virtually identical to that shown in Figure 1. A performance test for assessment of upper limb function in physical rehabilitation and research. If the purpose is to assess upper-limb recovery, there is strong evidence that the CAHAI is superior to the CAHAI-9; however, based on the difference in ROC curve areas, it is less clear whether the superiority is clinically important.


Practice Management Information Corp; Random assignment determined whether the treating therapist or the research therapist would complete the assessment first and which measure, the CAHAI or the ARAT, was administered first by the research therapist.

The difference in point estimates of the 2 CAHAI versions was less than the declared a priori clinical difference of 0. Tests and Measurements All Journals search input. In most cases Physiopedia articles are a secondary source and so should not be used as references. Within the context of our article, the greater the area under an ROC curve, the higher the probability that the measure would correctly identify true change in upper-limb function. The findings indicate that CAHAI-9 shows promise as an upper limb ability assessment for clients within 14 days of stroke.

The purposes of this study were: In a previously reported pilot study of 39 patients, we found the ROC curve areas to be 0. The content on or accessible through Physiopedia is for informational purposes only. The correlation between the scores of the 2 versions of the CAHAI at both the initial and follow-up visits was.

There was a problem during the HTTP request: Oxford University Press is a department of the University of Oxford. The current investigation focused on the first 2 criteria. Presumably, as better measures are developed, inferior measures will be discarded.

Good results as ar upper limb ability assessment for clients within 14 days of stroke. Functional evaluation of upper extremity use following stroke:
