Benefits of Rhythmic Auditory Stimulation and Lee Silverman Voice Treatment in a Parkinson's Disease Patient With Meningoencephalitis: A Case Report

Parkinson's disease (PD) is a neurological disorder characterized by motor and non-motor symptoms that significantly impact patients' quality of life. Meningoencephalitis, an inflammation of the brain and its surrounding membranes, exacerbates the neurological features of PD, leading to considerable disability. This case report describes a 73-year-old female with a five-year history of PD who presented with meningoencephalitis. She exhibited pyrexia, dyspnea, and neurological symptoms consistent with meningeal irritation. Diagnostic investigations indicated viral meningoencephalitis. Following medical management, the patient completed a four-week physical therapy program, including Lee Silverman voice treatment, rhythmic auditory stimulation, and proprioceptive neuromuscular facilitation exercises. These physiotherapy interventions focused on mobilization to improve range of motion, muscle strength, neuromuscular coordination, and functional ability. Quantitative outcome measures - such as the Unified Parkinson's Disease Rating Scale, Modified Hoehn and Yahr stage, and Parkinson's Disease Questionnaire-39 - showed positive changes following the intervention. The outcomes highlight the benefits of a multifaceted rehabilitation approach for patients with PD and concurrent meningoencephalitis. This case underscores the importance of initiating physiotherapy early to enhance motor outcomes and quality of life in patients with complex neurological conditions.
