Limb-Girdle Video Assessment

Limb-Girdle Video Assessment Concept Elicitation and Feasibility Study

The purpose of this study is to develop a new remote-based video assessment outcome measure for Limb-Girdle Muscular Dystrophy (LGMD) trials. The overall objectives for this study are: 1. Identify domains and tasks meaningful to participants with a Limb-Girdle Muscular Dystrophy (LGMD) for development of the LGVA, including considerations for subtype heterogeneity and functional subgroup branching; 2. Determine the feasibility and reliability of the LGVA with test-retest of the LGVA Video Capture Manual; 3. Assess and refine the LGVA Video Capture Manual to ensure standardization and incorporate feedback from participants; 4. Collect source material videos using the LGVA Video Capture Manual to support the development of scorecards for the LGVA.

Study Overview

• Status: Terminated
• Conditions: Limb-Girdle Muscular Dystrophy ; Subtypes 2A, 2B, and 2I

Detailed Description

The purpose of this study is to gain insight from people living with an LGMD and gather source material videos to develop and test Limb-Girdle Video Assessment (LGVA), a new outcome measure designed to assess changes in functional abilities of participants in LGMDs clinical trials. The LGVA is being designed as a remote video capture to assess nuanced changes in compensatory movement patterns over time. This study involves two stages. In the concept elicitation stage, the tasks for the LGVA Video Capture Manual will be finalized based on feedback from participants living with an LGMD 2A, 2B, or 2I in various stages of disease progression. After finalizing the LGVA Video Capture Manual, source material videos will be collected to evaluate the feasibility and appropriateness of the LGVA tasks, standardize capture procedures, and inform the development of scorecards for the LGVA.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Assessing the fluctuation of movement abilities of LGMDs patients via remote video capture.	Using the newly developed LGVA Video Capture Manual, participants are asked to record two sets of videos of them performing assigned tasks. Participants will have one week to complete each round of video capture, with approximately one month between each round. Videos will be captured remotely and uploaded through a secure platform.	January 2023 - March 2023

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Task Selection Survey	Electronic survey asking LGMDs patients about tasks and activities they perform in their daily life, and if/ how these are impacted by their LGMD symptoms.	August 2022 - September 2022
Focus Group	Small group discussion of participants with similar functional abilities to discuss the progression of symptoms and heterogeneity among subtypes.	September 2022 - October 2022
Exit Interview	After the feasibility video captures are complete, participants are asked about their experiences using the LGVA Video Capture Manual and the recording procedures.	January 2023 - March 2023
