Objective: To evaluate whether an 18-month, physical activity coaching program is more effective than standard care in terms of upper-limb activity. Design: A prospective, randomized controlled trial. Setting: Three municipalities in Norway. Population: A total of 380 persons with stroke. Intervention: The intervention group received follow-up visits and coaching on physical activity and exercise each month for 18 months after inclusion, by a physiotherapist. The control group received standard care. Main measures: The primary outcome, in this secondary analysis, was Motor Assessment Scale items 6, 7, and 8. Secondary outcomes were National Institute of Health Stroke Scale item 5, the Stroke Impact Scale domain 7, and the Modified Ashworth Scale in flexion/extension of the elbow. Results: In total, 380 persons with stroke were recruited, with mean (SD) age 72 (11) years, and baseline scores total National Institute of Health Stroke Scale was 1.4 (2.2)/1.6 (2.4) and Motor Assessment Scale items 6, 7 and 8 in the intervention/control group was 5.5 (1.2)/5.5 (1.2), 5.4 (1.4)/5.4 (1.3), and 3.6 (2)/3.5 (2), respectively. There was no significant difference between groups in terms of upper limb function in any of the Motor Assessment Scale items. In this population with minor stroke, upper-limb activity was good at three months post-stroke (74% of the maximum) and remained good 18 months later (77% of maximum). Conclusion: After intervention, there was no difference between the groups in terms of upper-limb activity.

Background: Multiple sclerosis (MS)-related knowledge is an important evaluation metric for health education interventions. However, few MS knowledge assessment tools are currently available for use. Objectives: This study aims to develop a reliable and valid Multiple Sclerosis Knowledge Assessment Scale (MSKAS) for use in the MS community and the general public. Methods: The MSKAS was developed using a Delphi study methodology and was administered to participants in the first open enrolment of the Understanding Multiple Sclerosis (UMS) online course. Rasch analysis was used to examine its psychometric properties and develop the final scale. Results: Experts from across the MS community participated in the development of the MSKAS, resulting in an initial scale of 42 items. Five hundred and forty-three UMS participants completed the MSKAS; 89% were female and 30% were people with MS. The final unidimensional 22-item scale has a person separation index of 2.16, a person reliability index of 0.82, an item separation index of 11.19, and a Cronbach’s alpha (kr-20) test reliability of 0.87. Conclusion: The MSKAS is a unidimensional scale with good construct validity and internal consistency. The MSKAS has the potential to be useful for the assessment of MS knowledge in research and clinical practice.

Objectives. (1) To develop two independent measurement scales for use as items assessing hand movements and hand activities within the Motor Assessment Scale (MAS), an existing instrument used for clinical assessment of motor performance in stroke survivors; (2) To examine the psychometric properties of these new measurement scales.Design. Scale development, followed by a multicenter observational study.Setting. Inpatient and outpatient occupational therapy programs in eight hospital and rehabilitation facilities in the United States and Canada.Participants. Patients(N=332)receiving stroke rehabilitation following left (52%) or right (48%) cerebrovascular accident; mean age 64.2 years (sd 15); median 1 month since stroke onset.Intervention. Not applicable.Main Outcome Measures. Data were tested for unidimensionality and reliability, and behavioral criteria were ordered according to difficulty level with Rasch analysis.Results. The new scales assessing hand movements and hand activities met Rasch expectations of unidimensionality and reliability.Conclusion. Following a multistep process of test development, analysis, and refinement, we have redesigned the two scales that comprise the hand function items on the MAS. The hand movement scale contains an empirically validated 10-behavior hierarchy and the hand activities item contains an empirically validated 8-behavior hierarchy.

Objective: The Colorado Cognitive Assessment (CoCA) was designed to improve upon existing screening tests in a number of ways, including enhanced psychometric properties and minimization of bias across diverse groups. This paper describes the initial validation study of the CoCA, which seeks to describe the test; demonstrate its construct validity; measurement invariance to age, education, sex, and mood symptoms; and compare it to the Montreal Cognitive Assessment (MoCA). Method: Participants included 151 older adults (MAge = 71.21, SD = 8.05) who were administered the CoCA, MoCA, Judgment test from the Neuropsychological Assessment Battery (NAB), 15-item version of the Geriatric Depression Scale (GDS-15), and 10-item version of the Geriatric Anxiety Scale (GAS-10). Results: A single factor confirmatory factor analysis model of the CoCA fit the data well, CFI = 0.955; RMSEA = 0.033. The CoCA’s internal consistency reliability was .84, compared to .74 for the MoCA. The CoCA had stronger disattenuated correlations with the MoCA (r = .79) and NAB Judgment (r = .47) and weaker correlations with the GDS-15 (r = -.36) and GAS-10 (r = -.15), supporting its construct validity. Finally, when analyzed using multiple indicators, multiple causes (MIMIC) modeling, the CoCA showed no evidence of measurement non-invariance, unlike the MoCA. Conclusions: These results provide initial evidence to suggest that the CoCA is a valid cognitive screening tool that offers numerous advantages over the MoCA, including superior psychometric properties and measurement non-invariance. Additional validation and normative studies are warranted.
