Adults with spina bifida: ambulatory performance and cognitive capacity in relation to muscle function

Abstract

Study design: Cross-sectional study.

Objective: Describe and compare ambulatory performance and cognitive capacity in relation to muscle function in an adult cohort with spina bifida. Also, explore factors associated with ambulation in participants with muscle function level 3.

Setting: Specialist clinic for adults with spinal cord disorders in Stockholm, Sweden.

Methods: A total regional cohort of adults (n = 219) with spina bifida was invited, 196 (104 women, mean age 35 years, SD 13 years) participated. Mode of mobility, cognitive capacity and muscle function were investigated. For participants with muscle function level 3, factors associated with ambulation were investigated using multivariate logistic regression analysis.

Results: In all, 84 participants (42%) were community ambulators, 22 (12%) household ambulators and 90 (46%) wheelchair users. There was a linear association between the lower degree of muscle function and scoliosis (P < 0.001). Mode of mobility varied despite similar muscle prerequisites in participants with muscle function level 3 (n = 58). Factors associated with ambulation in participants with muscle function level 3 were the absence of scoliosis, lower BMI and higher cognitive capacity.

Conclusions: Cognitive capacity and mode of mobility varied widely across the cohort. However, in participants with muscle function level 3, despite similar muscular prerequisites, a large variation in the mode of mobility was found, suggesting that other factors were involved. It is important to prevent scoliosis, support a healthy lifestyle, as well as offer cognitive screening and support to promote ambulatory function and optimise independence in the everyday lives of adults with spina bifida.
