Digital Monitoring of Upper Limb Function in Non-Ambulant DMD (Acti-nRoll)
Feasibility, Reliability, Clinical Validity and Sensitivity of Digital Outcomes to Monitor Upper Limb Function in Non-ambulant Patients With Genetically Confirmed Duchenne Muscular Dystrophy (DMD)
Duchenne Muscular Dystrophy (DMD) is a rare genetic disorder caused by the absence of dystrophin, leading to progressive muscle degeneration. Symptoms typically begin in early childhood and result in loss of ambulation by early adolescence, followed by cardiorespiratory complications. Although early treatment, including corticosteroids and emerging therapies, can slow disease progression, sensitive tools to monitor functional decline-particularly in non-ambulant patients-remain limited.
Current assessments rely primarily on clinical scales and hospital-based evaluations, which may not detect subtle changes or reflect real-life function. Digital outcome measures derived from wearable sensors offer a promising approach for continuous, objective monitoring in daily life. This study aims to evaluate the feasibility, reliability, clinical validity, and sensitivity of digital measures to assess upper limb function in non-ambulant patients with genetically confirmed DMD. The Syde device, previously validated in ambulant DMD patients, will be investigated for its applicability in this population.

Syde是一种创新设备,旨在用于家庭环境中。
它由两个表格传感器组成,每个传感器都包含一个磁惯性传感器,该传感器记录了线性加速度,角速度,动作的磁场在各个方向上。两只手表可以作为手表或脚踝附近戴上。
将使用Myotools进行以下功能的最大力量的动力学测量:Palmar Grip(Myogrip)和Thumb-Index Pinch(Myopinch)。
测试将在主要方面实现。
在测试期间将鼓励患者。
他们将进行三个试验,并将输入最佳分数。
This test consists of a set of small manoeuvres (lifting a box, writing, etc.) designed to evaluate the upper-limb functionality of non-ambulatory patients.
It was developed specifically for use in cases of Duchenne muscular dystrophy.
The Brooke Upper Extremity Functional Rating Scale will be used to assess the global functional level of upper limb involvement.
This 6-point ordinal scale classifies patients according to their highest achievable upper limb function, from full arm abduction to absence of useful hand function.
Forced Vital Capacity (FVC) will be assessed using standardized spirometry procedures.
The primary parameter will be FVC expressed as percentage of predicted values.
At least three acceptable and reproducible maneuvers will be performed according to standard guidelines.
The CGI-S is a clinician-rated scale used at baseline to assess the overall severity of the participant's condition, based on all available clinical information.
The rating reflects the clinician's judgment without standardized scoring rules and must be performed by a clinician experienced in Duchenne Muscular Dystrophy.
The CGI-S evaluates three domains: physical motor function, respiratory function, and bulbar function.
It is completed after all other study assessments (excluding patient-reported outcomes) to ensure a comprehensive evaluation.
The CGI-C is used at each follow-up visit to assess changes in the participant's condition relative to baseline.
It provides a clinician-determined measure of improvement or worsening, based on overall clinical judgment rather than fixed criteria.
Like the CGI-S, it covers physical motor, respiratory, and bulbar domains and is performed after all other study assessments (excluding patient-reported outcomes).
The CGI-C is expected to track consistently with prior CGI-S evaluations, reflecting changes in disease status over time.
The PGI-S (Patient Global Impression of Severity) is a simple, validated, single-item self-administered scale used to assess the current severity of a patient's condition.
Widely used in clinical trials, it allows patients to rate their condition, on a 4- to 6-point scale (from 'Normal' to 'Very severe').
