Reliability of the motor learning strategy rating instrument for children and youth with acquired brain injury.
ABSTRACT To evaluate reliability and feasibility of the Motor Learning Strategy Rating Instrument (MLSRI) in children with acquired brain injury (ABI). The MLSRI quantifies the extent to which motor learning strategies (MLS) are used within physiotherapy (PT) interventions.
PT sessions conducted by ABI team physiotherapists with a convenience sample of children with ABI (4-18 years) were videotaped and independently scored later by two raters trained in MLSRI use. Intraclass correlation coefficients (ICCs) and 95% confidence intervals (CIs) estimated intra- and inter-rater reliability.
Eighteen PT sessions were evaluated. Intra- and inter-rater reliability ICCs for total score were 0.86 (95% CI: 0.66-0.94) and 0.50 (95% CI: 0.08-0.78), respectively. MLSRI category ICCs were 0.56-0.86 (intra-rater) and 0.16-0.84 (inter-rater).
Intra-rater reliability of MSLRI total score was excellent. Moderate inter-rater reliability may partially be due to inconsistent item interpretation between raters. Revisions and further reliability testing are required before recommending the MLSRI for clinical and research use.

ABSTRACT: PURPOSE:: To evaluate and compare the interrater reliability of the Motor Learning Strategy Rating Instrument (MLSRI) within usual and virtual reality (VR) interventions for children with acquired brain injury. METHODS:: Two intervention sessions for each of 11 children (total, 22) were videotaped; sessions were provided by 4 physical therapists. Videotapes were divided into usual and VR components and rated by 2 observers using the MLSRI. A generalizability theory approach was used to determine interrater reliability for each intervention. RESULTS:: Interrater reliability for usual interventions was high for the MLSRI total score (g-coefficient, 0.81), whereas it was low for the VR total score (g-coefficient, 0.28); MLSRI category g-coefficients varied from 0.35 to 0.65 for usual and from 0.17 to 0.72 for VR interventions. CONCLUSION:: Adequate reliability was achieved within ratings of usual interventions; however, challenges related to MLSRI use to rate VR-based interventions require further evaluation.Pediatric physical therapy: the official publication of the Section on Pediatrics of the American Physical Therapy Association 11/2012;
