Aquatic Physical therapy in a patient with Limb-Girdle Muscular Dystrophy, type 2b: a case report

Abstract

INTRODUCTION: Limb-Girdle Muscular Dystrophy, Type 2B (LGMD2B), is a rare, hereditary, progressive neuromuscular degenerative disease coursing with progressive impairments in motor and functional capacity. OBJECTIVE: To describe and analyze the effects of aquatic physical therapy on the functionality, muscle strength, range of motion, and quality of life of a patient diagnosed with LGMD2B attended on an outreach program. METHODS: A female patient, 32 years old, single, with genetic diagnosis of LGMD2B, level 5 at Vignos scale (modified by Garder-Medwin e Walton). The case reports the Aquatic Physical Therapy rehabilitation protocol (hydrokinesiotherapy) and its impacts on muscle strength, range of motion, functional capacity, and patient quality of life (CAAE No. 43505321.0.0000.0018). RESULTS: The aquatic physical therapy protocol, composed of 12 sessions, 60 minutes/2x/week, resulted in improvements in overall functional capacity and a 9.52% increase of distal motor function, 100% increase in handgrip strength, and increase up to the upper limit (grade 5) on the MRC scale for several of the muscles tested, in addition to increased range of motion and expressive improvement in Quality of Life. CONCLUSION: The patient' functional improvement suggests that water-based physical therapy rehabilitation, at mild to moderate exercise intensity, is a safe and effective therapeutic option for improvement muscle strength, range of motion, functional capacity, and quality of life in LGMD2B patients.
