Home-Based, Therapist-Assisted, Therapy for Young Children With Primary Complex Motor Stereotypies

Research output: Contribution to journalArticle

Abstract

Background: Complex motor stereotypies (CMS) typically begin before age three years and include rhythmic, repetitive, fixed movements that last for seconds to minutes and can be interrupted with distraction. Objective: We evaluated the effectiveness of a home-based, parent-provided therapy accompanied by scheduled telephone calls with a therapist, in five- to seven-year old children with primary CMS. Methods: Eligible families received an instructional digital versatile disk (DVD) written instructions, and scheduled telephone contacts with a therapist at baseline (DVD receipt), one, three, and eight weeks later. At each call, parents completed outcome measures and received feedback. Outcome scales Stereotypy Severity Scale (SSS) Motor and Impairment scales and a Stereotypy Linear Analogue Scale (SLAS) were also completed via the Iinternet (REDCap)—at screening, one and two months post-baseline call. At study conclusion, participants were divided into an intent-to-treat (ITT; had at least one call) or a lost-to-follow-up (LTF) group. Results: Thirty-eight children (mean = 6 years ± 11 months) were enrolled. The LTF group (n = 14) had significantly higher scores than the ITT (n = 24) group on all attention-deficit/hyperactivity disorder ratings (P < 0.01), but not stereotypy severity. Primary outcome scores, acquired by telephone and REDCap, showed a significant reduction in SSS Motor and Impairment scores between the initial and the last completed evaluation (P ≤ 0.001). Calculated change ratios were SSS Motor −0.23/−0.30 (cal/REDCap); SSS Impairment −0.31/−0.32; and SLAS −0.54 (REDCap). Clinical improvement was further supported by results from a parent improvement scale and end of study questionnaires. Conclusions: Home-based, parent-administered behavioral therapy supplemented by telephone contact with a therapist is effective in reducing complex motor stereotypies in children.
