Neuromuscular Ultrasound in ALS

Brief Summary:

Amyotrophic Lateral Sclerosis (ALS) is a progressive fatal neurodegenerative disease affecting motor neurons. Early diagnosis is essential for the success of clinical trials and objective biomarkers are needed for monitoring disease progression. Nerve and muscle ultrasound may provide this information.

This study will collect pilot data to evaluate the value of muscle and nerve ultrasound to identify and monitor disease progression in ALS.

Condition or disease Intervention/treatment
ALS Other: Ultrasound of nerve and muscle

Study Type : Observational
Actual Enrollment : 40 participants
Observational Model: Case-Control
Time Perspective: Prospective
Official Title: Ultrasonography in Amyotrophic Lateral Sclerosis as a Predictor of Disease Progression and Tool in Diagnosis: a Pilot Study
Study Start Date : February 2013
Actual Primary Completion Date : March 2015
Actual Study Completion Date : March 2015

Group/Cohort Intervention/treatment
Control Group
No intervention to be performed.
Ultrasound Group
All will receive nerve and muscle ultrasound.
Other: Ultrasound of nerve and muscle
Ultrasound of 6 muscles and 2 nerves will be performed.

Primary Outcome Measures :
  1. Abnormalities at onset: Ultrasound vs. Electromyography [ Time Frame: 1 year ]
    Ultrasound measures will be compared to electromyography measures at the patient's initial assessment. The number of abnormal muscles will be counted using each technique and analyzed to determine if one test is superior.

Secondary Outcome Measures :
  1. Ultrasound Predicting Outcome at 1 year [ Time Frame: 1.5 years ]
    The initial ultrasound measures and patient outcomes, as measured by standard validated scales, will be assessed at periodic intervals for one year. Analysis will be performed to determine if ultrasound measures can predict the clinical course.
