-Spinal and bulbar muscular atrophy (SBMA) is an inherited disorder that affects men. People with SBMA often have weakness throughout the body, including the muscles they use for swallowing, breathing, and speaking. We do not know if exercise helps or harms people with SBMA.
-To see if a 12-week program of either functional exercise or stretching exercises will improve strength, function, or quality of life in people with SBMA
Objective: Spinal and bulbar muscular atrophy (SBMA), or Kennedy s disease, is a slowly progressive, X-linked motor neuron disease for which there is currently no treatment. It is caused by a mutation in the androgen receptor that results in a polyglutamine repeat expansion. The role of exercise in motor neuron disease research is debated. Although SBMA is believed to be primarily a neuronopathy, the potential effect of aberrant androgen receptor activity on muscle leads exercise to be of uncertain utility in this population. Our objective is to examine the safety and efficacy of exercise regimens in Kennedy s disease.
Study Population: We aim to enroll 80 men with genetically confirmed Kennedy s disease.
Design: This will be a randomized, evaluator blinded, trial with 25 subjects in each exercise arm. Following informed consent, the subjects will undergo an initial medical and physical evaluations followed by a series of neurological tests and blood work over a two-day outpatient visit at the NIH. The subjects will provide blood work for analysis of hormonal levels and assessment of any potential muscle damage. On the second day of their visit, the subjects will be randomized and taught a series of either functional or stretching exercises that they will engage in as part of the study and control arms, respectively. Following the baseline visit to NIH, the subjects will be monitored throughout the study with telephone contacts and other measures including video recording to monitor their progress and compliance. The subjects will return to the NIH at the end of a 12 week period at which time the physical and laboratory testing will be repeated. After the 12 week exercise period there will be a four week period where we will follow-up with the participants by telephone and e-mail. At the end of the trial all of the subjects will be informed of the study results and given the opportunity to learn the exercises if they are found to be beneficial.
Outcome Measures: The primary outcome measure used will be the Adult Myopathy Assessment Tool (AMAT). Secondary outcome measures will involve quantitative muscle analysis (QMA), the Timed Up and Go (TUG) test, a quality of life measure (SF-36v2TM), adverse event questionnaires, a Computerized Dynamic Posturography (CDP) assessment of balance, accelerometer measurements of exercise effort, and progressive height sit-to-stand testing. Several exploratory biomarkers that may be affected by exercise will be evaluated, including insulin-like growth factor-1 (IGF-1), insulin-like growth factor binding protein 3, testosterone, growth hormone, and creatine kinase. Beck Depression Inventory (BDI) testing will also be used to determine if the subjects mood is affected by exercise. Qualitative sub-study questions, international index of erectile function, Block brief food questionnaire, Aggression Questionnaire, Activities-specific Balance Confidence (ABC) scale, Fatigue Symptom Inventory, and physical activity survey measures will also be employed.
