Amyotrophic Lateral Sclerosis (ALS) is a progressive and fatal neurological disease.
An exhaustive and frequent clinical evaluation can lead to establish an adequate and early treatment of the consequences of its evolution.
- To evaluate the evolution of diaphragmatic and peripheral neuromuscular degeneration by ultrasound examination in patients with ALS and to establish possible evolution patterns.
- To verify the relationship between the degenerative peripheral and diaphragmatic neuromuscular changes evaluated by ultrasonography and changes in clinical scales frequently used.
- To compare the ultrasonographic features of subjects with ALS and a sample of healthy subjects Methods. A longitudinal observational study in a consecutive sample of patients diagnosed with ALS will be realized. All the patients will be examined 3 times, with an interval of at least 3 months between tests. Bilateral and cross sectional ultrasonography of several peripheral muscles and diaphragm will be performed at rest and during muscle contraction. All the images will be processed and analyzed for obtaining morphometric variables (muscle thickness) and textural ones (echogenic variation, entropy, homogeneity, textural contrast and correlation). Frequency of twitches will be also recorded in peripheral muscles.Also clinical features will be noted, every time of the 3 exams, from Revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-r), British Medical Council Research Scale(MRC), and routine pulmonary tests.

- Measuring thickness in peripheral muscles. [ Time Frame: 3 months ]These measurements will be carried out in the biceps brachialis, forearm flexors, thenar eminence muscle, quadriceps and tibialis anterior which will be compared between patient with ALS and control group.
- Measuring echointensity and in peripheral muscles. [ Time Frame: 3 months ]These measurements will be carried out in the biceps brachialis, forearm flexors, thenar eminence muscle, quadriceps and tibialis anterior which will be compared between patient with ALS and control group.
- Measuring sonoelastography in peripheral muscles. [ Time Frame: 3 months ]These measurements will be carried out in the biceps brachialis, forearm flexors, thenar eminence muscle, quadriceps and tibialis anterior which will be compared between patient with ALS and control group.
- Thickness Fraction of the Diaphragm in ALS patients and control group. [ Time Frame: 3 months ]It is calculated as the difference between thickness at end inspiration and end expiration
- Diaphragmatic Excursion (quiet and forced) of the Diaphragm in ALS patients and control group [ Time Frame: 3 months ]Displacement of the right diaphragm dome
- Measurement muscle fasciculations [ Time Frame: 3 months ]Each peripheral muscle will be screened during 30 seconds
- Measurement muscle strength [ Time Frame: 3 months ]Graded on the medical research council scale. This scale grades muscle power on a scale of 0 to 5
- Measurement Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-r) [ Time Frame: 3 months ]Questionnaire with 12 items with a score from 0 to 4 each item. These 12 questions are about: Speech, Swallowing, Handwriting, Cutting food and handling,utensils,Dressing and hygiene,Turning in bed and adjusting bed clothes, Walking, Climbing stairs, Dyspnea, Orthopnea and Respiratory insufficiency. This Scale
- Measuring Forced Vital Capacity [ Time Frame: 3 months ]This volume expressed in liters will be measured in supine and seated positions.
- Maximal Inspiratory Pressure (MIP) [ Time Frame: 3 months ]Measure of the strength of inspiratory muscles expressed in centimeters of water, is the highest mouth pressure sustained for 1 s during a maximum inspiratory effort
- Sniff- nasal inspiratory pressure (SNIP) [ Time Frame: 3 months ]It consists of measuring nasal pressure in an occluded nostril during a maximal sniff performed through the contralateral nostril, expressed in centimeters of water
- Peak Cough Flow (PCF) [ Time Frame: 3 months ]Maximal peak cough flow expressed in liters per minute
- Partial Pressure of Carbon Dioxide in Arterial Blood (PaCO2) [ Time Frame: 3 months ]Obtained by a radial arterial blood sample and expressed in millimeters of mercury
- Cumulative time percentage with SpO2 under 90% (CT90) [ Time Frame: 3 months ]SpO2 is an estimate of arterial oxygen saturation expressed in percentage under 90% obtained from a nocturnal oximetry
