简要总结
This is a single-session, case-control study that incorporates digital tools for assessing speech and motor function in motor neuron disease. Patients with motor neuron disease (including amyotrophic lateral sclerosis (ALS), primary lateral sclerosis (PLS), and progressive muscular atrophy (PMA)) and age-matched healthy controls will be enrolled. Subjects will complete a speech and handwriting assessment during the study visit on a tablet computer (BioSensics LLC, Newton, MA). We will explore whether these digital biomarkers are sensitive to functional disease severity as reported by the ALS Functional Rating Scale - Revised (ALFRS-R) [1]. We will also compare assessment data between the patient and control groups.
详细描述
ALS is a progressive neuromuscular disease that causes weakness and inevitably affecting multiple motor processes within the body. To assess changes in functional mobility, clinicians and clinical investigators often rely on the ALS Functional Rating Scale - Revised (ALSFRS-R), a standardized 12-item questionnaire that has been in use for decades. Although thoroughly validated, this scale has received criticism for providing a coarse reflection of a patient's disease, scaling non-linearly within and across functional domains, and without the sensitivity to reflect day-to-day variability or small but meaningful changes.
This study includes collection of digital speech and fine motor control assessment data at a single study visit. Features extracted from this data will be compared with standard clinical disease outcome measures and also the features derived from control participant data. We will use these comparisons to explore the use of these digital assessments in capturing the range of functional changes that occur in ALS and the related motor neuron diseases of PLS and PMA that are regularly treated in the ALS clinic.

结局指标
主要结局
Speaking rate during a standardized passage
时间窗: baseline
Speaking rate, in words per minute, will be determined from an audio recording of a standardized reading passage.
Residual on spiral tracing task
时间窗: baseline
Handwriting tasks include tracing of a spiral. The average residual, or deviation from the target spiral (in pixels), will be determined from the handwriting file associated with the tracing task.
次要结局
- ALS Functional Rating Scale- Revised (ALSFRS-R)(baseline)
- Strength testing(baseline)
- Forced vital capacity (FVC)(baseline)
- Upper motor neuron function(baseline)
