Source material collection of videos to develop the Mitochondrial Video Assessment (MVA) for patients with mitochondrial myopathies.
This observational research is being conducted to facilitate the development of 2 related, disease-specific outcome measures assessing ease of movement in PMM and PolG clinical trials. The Mitochondrial Video Assessment (MVA) utilizes remote video capture to assess subtle shifts in compensatory movement patterns and measure change in function over time, and the Current State Questionnaire asks participants about external factors in their daily lives which may influence fluctuations in their symptoms. As part of the questionnaire, participants are asked to rate their own perception of their functional ability using a Patient Global Impression of Severity (PGI-S) scale.

Casimir
Kingston, Massachusetts, United States
Source Material Videos
Initiate feasibility testing and collect source material videos from patients with Primary Mitochondrial Myopathy (PMM, n=35) or a PolGamma (PolG) mutation (n=15) to facilitate development of the Mitochondrial Video Assessment (MVA).
Time frame: 2 weeks
PGI-S
Identify external factors which may influence participant performance on functional assessments and collect Patient Global Impression of Severity (PGI-S) at the time of each capture to facilitate the development of a patient-reported Current State Questionnaire to be deployed in conjunction with the MVA.
Time frame: 2 weeks
