Full Study Summary:

A new strength measurement device called Accurate Test of Limb Isometric Strength (ATLIS) was developed to precisely and conveniently measure static limb strength in patients with ALS. We will compare ATLIS data with data from two commonly used ALS outcomes measures, the ALS Functional Rating Scale-Revised (ALSFRS-R) and slow vital capacity (SVC) in a prospective, longitudinal study. All three outcomes measures will be performed on 100 subjects collected preferably at bi-monthly clinic visits during the study period.

Four sites will participate in data collection for this study and will enroll approximately 20-30 subjects per site. Subjects will be tested every 1 to 4 months for up to two years. Subjects will be tested at each visit using ATLIS, ALSFRS-R questionnaire and slow vital capacity testing.

Study Sponsor:

The ALS Association

Participant Duration:

Total time enrolled in study is up to 2 years. Subjects will spend about 45 minutes at each visit to the clinic (every 1 to 4 months) to complete study procedures.

Inclusion criteria:
• Subjects 18 years or older diagnosed with clinically possible, laboratory supported probable, probable or clinically definite ALS according to the World Federation of Neurology Revised El Escorial Criteria.
• Capable of providing informed consent and complying with trial procedures.
• Active movement of at least two limbs at the time of study entry
