Digital Assessment of Speech and Fine Motor Control in ALS

July 3, 2025 updated by: Andrew Geronimo, Milton S. Hershey Medical Center
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.

Study Overview

Detailed Description

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Speaking rate during a standardized passage
Time Frame: baseline
Speaking rate, in words per minute, will be determined from an audio recording of a standardized reading passage.
baseline
Residual on spiral tracing task
Time Frame: 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.
baseline

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
ALS Functional Rating Scale- Revised (ALSFRS-R)
Time Frame: baseline
The ALSFRS-R measures 12 aspects of physical function, ranging from one's ability to swallow and use utensils to climbing stairs and breathing. Each function is scored from 4 (normal) to 0 (no ability), with a maximum total score of 48 and a minimum total score of 0.
baseline
Forced vital capacity (FVC)
Time Frame: baseline
FVC is collected at clinical appointments by a respiratory therapist. FVC is the volume of air that is forcefully expelled into a spirometer. FVC is expressed as a percentage (%) of predicted volume against an age, height, and ethnicity matched standard. The best result of three trials is used.
baseline
Upper motor neuron function
Time Frame: baseline
Reflex testing is performed by the attending neurologist at clinical appointments. Bilateral biceps, triceps, and brachioradialis reflexes will be documented according to Modified Ashworth Scale grade 0 (no tone increase) to 4 (limb rigid). Total score for bilateral muscle groups ranges from 0 to 24.
baseline
Strength testing
Time Frame: baseline
Strength testing is performed by the attending neurologist at clinical appointments. Bilateral deltoids, biceps, triceps, wrist extension, and interossei strength will be documented according to Medical Research Council (MRC) grade 0 (no power) to 5 (normal power). Total score for bilateral muscle groups ranges from 0 to 50.
