This is an observational study, no drug (marketed or investigational) will be provided as part of the study, and the study procedures will have no impact on the medical care delivered to patients participating in this study. The overall study data collection period is planned to last up to 5 years with assessments occurring at baseline, and every 6 months thereafter for a total period of 3 years.
Medical records for enrolled patients will be abstracted at baseline and annually to obtain clinical information, and data will be recorded for the study. Eligible patients will be asked to provide informed consent and to complete semi-annual patient surveys and functional assessments. The patient surveys will include selected PRO instrument(s) along with additional questions to characterize the patient's perception of disease.
Neuromuscular disease can be characterized by progressive muscle degeneration, impaired pulmonary status, and decreased cardiac function.(1-8) Additionally, these neuromuscular disorders can be rare, and therefore difficult to establish the natural progression of each disease.The natural history of each neuromuscular disorder provides valuable information about the specific progression of the disease, which can guide in understanding which outcomes to measure in order to show change for clinical trials. Experimental treatments for many of these neuromuscular disorders are currently being assessed in clinical trials with others in the pipeline for upcoming clinical trials in the near future. Thus, the need to reliably and objectively detect small, meaningful changes in daily functional activities in order to serve as a supportive measure of efficacy in clinical trials is of great importance.
Functional and strength measures have been utilized as primary, secondary or exploratory outcomes in clinical trials studying the efficacy of drug therapies. Many of these outcome measures have been shown to be reliable and have been validated in neuromuscular disease.
This longitudinal study aims to characterize the clinical progression and functional impact on patients with neuromuscular disorders over time by evaluating functional and patient-reported outcomes (PROs). The association between functional impairment and long-term outcomes, such as loss of mobility, falls, and quality of life, will be examined.
- Strength [ Time Frame: 6 months ]
- Force production testing using standardized equipment
- Walking speed [ Time Frame: 6 months ]
- Timing how fast the person can walk 100 meters
- Physical functioning [ Time Frame: 6 months ]
- Observing or surveying how well a person can perform activities of daily living

Suspected LGMD2A or LGMD2E by symptoms and having a family member diagnosed with 2A or 2E, or have genetic confirmation of one of these two types of LGMD themselves.
Perform assessments to the best of their ability with reliable results as deemed by the evaluator. Ability to attend scheduled appointments Ability to provide informed consent (or assent for ages 9-18)
Confirmed diagnosis of neuromuscular disorder other than LGMD2E or LGMD2A Has a medical condition or extenuating circumstance that, in the opinion of the investigator, might compromise the subject's ability to comply with the protocol required testing or procedures or compromise the subject's well being, safety, or clinical interpretability.
