Abstract

The impacts of potentially treatable psychological parameters on quality of life are relatively unreported in adults with Facioscapulohumeral, Becker and Limb-girdle muscular dystrophy. The purpose of this study was to compare quality of life, psychological parameters, and physical function between adults with muscular dystrophy and controls, and to examine relationships among these parameters in muscular dystrophy. Twenty-one adults with muscular dystrophy (n = 7 Becker, n = 8 Facioscapulohumeral, n = 6 Limb-girdle) and ten age-matched controls participated. Outcome measures were health-related quality of life, depressive symptoms, trait anxiety, self-esteem, physical self-worth and six-minute walk distance. Quality of life scores were lower in the muscular dystrophy groups than the control (p < .05). Depressive symptoms had the greatest association with quality of life in the Mental Health domain (r= -0.89, p < .001). Depressive symptoms also had the most associations with quality of life (7 of 10 domains), followed by trait anxiety (6 of 10 domains), physical self-worth (5 of 10 domains), self-esteem (4 of 10 domains) and six-minute walk distance (3 of 10 domains). Psychological parameters and, to a lesser extent, physical function impact quality of life in muscular dystrophy. This study provides a rationale to include psychological assessment and treatment within muscular dystrophy healthcare.
