Progressive resistance training for persons with intellectual disabilities and visual impairment

Abstract

Background: Knowledge concerning the feasibility and effects of progressive resistance training (PRT) for persons with intellectual disabilities and visual impairment who are categorized in Gross Motor Function Classification System (GMFCS) Level 1 is limited. The aim of our study was to evaluate feasibility and effect of PRT on participants' Quadriceps strength and personal goals. Methods: Eight Participants followed a PRT program for 10 weeks. Feasibility was determined by percentage of attendance and compliance. The effect of PRT was analyzed with a linear mixed model (p < 0.05) and by normalized bootstrap (95% CI). Results: Participants attended 87.8% of the sessions and trained according to the PRT program, indicating sufficient compliance. Quadriceps strength increased significantly by 69%, and participants' personal goals were achieved. Conclusion: PRT is a feasible and potentially effective method for increasing Quadriceps strength as well as achieving personal goals in persons with intellectual disabilities and visual impairment with GMFCS Level 1.
