Motor improvement in children with PMM2-CDG syndrome following a six-month rehabilitation treatment utilising whole-body vibration; a retrospective study.

OBJECTIVE:The aim of this study was to assess the effect of a six-month interval rehabilitation treatment on motor function of children with PMM2-CDG syndrome (#212065 Congenital disorder of glycosylation, Type Ia; CDG1A, OMIM catalogue number). METHODS:The concept 'Auf die Beine' (Center for Prevention and Rehabilitation of the University of Cologne, Germany) combines two short inpatient stays (1 to 2 weeks) with a six-month whole-body vibration (WBV) home-training program. 13 patients with PMM2-CDG syndrome participated in this concept from 2006 until 2015. Assessments at start, six months and 12 months (follow-up): Gross Motor Function Measure (GMFM-66), One-Minute Walk Test (1MWT) and instrumented gait analyses. RESULTS:The GMFM-66 (9 of 13 children) improved by 5.3 (mean) points (SD 3.2) at 12 months (p=0.0039). The 1MWT (6 of 13 children) improved by 19.17 meter (SD 16.51) after 12 months (p=0.0313). Gait analysis (9 of 13 children) measured by pathlength/distance ratio improved by -0.8 (SD 1.9) at 12 months (p=0.0195). CONCLUSION:Patients with PMM2-CDG syndrome benefit from the interval rehabilitation program 'Auf die Beine' including WBV.
