Temporal stability and responsiveness of the Montreal Cognitive Assessment following acquired brain injury.

OBJECTIVES: To evaluate the temporal stability and responsiveness of the Montreal Cognitive Assessment (MoCA) in acquired brain injury (ABI). RESEARCH DESIGN AND METHODS: English-speaking adults with stroke or moderate-to-severe traumatic brain injury were administered alternate forms of the MoCA (version 1, then 2), 6 weeks apart. Chronic group participants (n = 40) were community-dwelling, at least 1 year post-ABI (mean = 12.1 years, SD = 9.0), and presumed clinically stable. Sub-acute group participants (n = 36) were 30.8 days post-ABI (SD = 12.4) and were undergoing intensive rehabilitation. Individuals with an unstable medical or psychiatric condition or severe receptive aphasia were not eligible. RESULTS: The chronic group scored 21.6 (SD = 4.5) initially and 22.7 (SD = 3.8) on the second administration, demonstrating a small but significant practise effect (p = 0.009). The Pearson test-re-test correlation coefficient was 0.83. Using reliable change methodology in the chronic group, the 80% confidence interval (CI) for change across the two administrations was -2 to +4, adjusting for practise. Applied to the sub-acute group, 39% improved and 0% declined. CONCLUSIONS: The MoCA is a brief standardized tool that appears useful for monitoring cognitive change after ABI. The findings enable clinicians to detect statistically reliable change across serial MoCA administrations in individuals with an ABI.

Validity of the walking scale for spinal cord injury and other domains of function in a multicenter clinical trial.

OBJECTIVE: To demonstrate criterion (concurrent and predictive) and construct validity of the Walking Index for Spinal Cord Injury (WISCI) scale and other walking measures in the Spinal Cord Injury Locomotor Trial (SCILT). DESIGN: Prospective multicenter clinical trial of a walking intervention for patients with acute traumatic spinal cord injury (SCI). PARTICIPANTS/ METHODS: Body weight-supported treadmill training was compared to overground mobility training in 146 patients with incomplete SCI (C4 to L3) enrolled within 8 weeks of onset and treated for 12 weeks. Primary outcome measures were the Functional Independence Measure (FIM), 50-foot walking speed (50FW-S), and 6-minute walking distance (6MW-D), tested 3, 6, and 12 months after entry. Secondary measures were the Lower Extremity Motor Score (LEMS), Berg Balance Scale (BBS), WISCI, and FIM locomotor score (LFIM), assessed at 6 centers by blinded observers. Data for the 2 arms were combined since no significant differences in outcomes had been found. RESULTS: Correlations with WISCI at 6 months were significant with BBS (r = .90), LEMS (r = .85), LFIM (r = .89), FIM (r = .77), 50FW-S (r = .85), and 6MW-D ( r = .79); similar correlations occurred at 3 and 12 months. Correlations of change scores from baseline WISCI were significant for change scores from baseline of LEMS/BBS/LFIM. Correlation of baseline LEMS and WISCI at 12 months were most significant (r = .73). The R(2) of baseline LEMS explained 57% of variability of WISCI levels at 3 months. CONCLUSION: Concurrent validity of the WISCI scale was supported by significant correlations with all measures at 3, 6, and 12 months. Correlation of change scores supports predictive validity. The LEMS at baseline was the best predictor of the WISCI score at 12 months and explained most of the variance, which supported both predictive and construct validity. The combination of the LEMS, BBS, WISCI, 50FW-S, and LFIM appears to encompass adequate descriptors for outcomes of walking trials for incomplete SCI.

Concordance in goal setting between patients with multiple sclerosis and their rehabilitation team.

OBJECTIVE: To determine the concordance between patients with multiple sclerosis and their clinical team members on the identification of goals for an inpatient rehabilitation stay. DESIGN: Prospective cohort study of patients admitted for rehabilitation in an adult inpatient neurospinal unit at a Rehabilitation Centre in Ottawa, Canada. Twenty-seven patients (11 men and 16 women, mean age of 45.3 yrs) with either a laboratory or a clinically supported diagnosis of multiple sclerosis. Patients rated 55 goals from a preexisting list, indicating the importance of each goal to be addressed during the inpatient stay. The goals fell into five broad domains of health/medical issues, daily activities, mobility, community life, and personal well-being. Patients also identified their five most important individual goals. In a separate session, the clinical team also rated the 55 goals in relation to each patient and identified an independent list of the five most important rehabilitation goals. Main outcome measures included concordance between patient and team ratings in the identification of goals, ratings of the likelihood of success of achieving each goal, and ratings of the amount of change required to realize a minimal clinically important difference. RESULTS: The patients and the team agreed on an average of 1.7 of the patient's five top-rated goals. Compared with the team, patients gave higher importance ratings to goals within the health/medical, mobility, and daily activities domains. They also considered that a greater average improvement would be required to achieve a meaningful benefit, and they gave higher ratings of the likelihood of success in achieving their selected goals. CONCLUSION: Patients with multiple sclerosis and clinical team members do not necessarily agree on specific goals for a rehabilitation stay. Patients may also have greater expectations than clinicians with respect to the amount of improvement and the likelihood of achieving their goals.
