Nocturnal PtcCO2 Monitoring in Patients With Amyotrophic Lateral Sclerosis (ALS)
Amyotrophic Lateral SclerosisAmyotrophic lateral sclerosis (ALS) is a neurodegenerative disease affecting motoneurons, with a prevalence around 5/100.000. Respiratory muscle involvement is a major feature in ALS and remains the main prognostic factor. Timing and rate of progression of this respiratory muscle involvement is also highly variable among individuals. Respiratory manifestations justify a careful follow up including clinical evaluation, pulmonary function tests and blood gases. Prognostic value of respiratory muscle assessment has been clearly demonstrated in ALS, although several cut off values have been published. The clinical benefit of non invasive ventilation (NIV) is well established in ALS, but the optimal criteria for its initiation remain debated . The 1999 consensus for NIV selected classical criteria to consider NIV in patients with respiratory symptoms suggesting hypoventilation: daytime hypercapnia (PaCO2 > 45 mmHg), nocturnal SaO2 < 89 % more than 5 consecutive minutes and for progressive neuromuscular disorders (NMD) (mainly ALS), a vital capacity (VC) < 50 % pred or a PImax < 60 cmH2O. Besides daytime clinical and PFT assessment, nocturnal evaluation is essential in ALS. The prevalence of sleep apnea ranges from 16 % to 76 %. Transcutaneous PCO2 (tcPCO2) is an attractive technique to evaluate non invasively nocturnal hypoventilation. The technique is well validated in different settings. Its use in neuromuscular disorders (NMD) is recent. In particular one study has demonstrated a high predictive value of tcPCO2 for the development of daytime hypoventilation within 1 year. To our knowledge, this technique has not been specifically assessed in ALS. There is a potential role for nocturnal PtcCO2 monitoring in the close follow up of ALS patients. Indeed, a close respiratory follow up of ALS patients is essential to determine the optimal timing of NIV, avoiding the occurence of unexpected acute respiratory failure.
Evaluation of Usability and Human Factors in the Novus System
Drop FootMuscle Weakness2 moreThe Novus system intended to provide ankle dorsiflexion and knee flexion or extension in individuals with foot drop and thigh muscle weakness, following an upper motor neuron injury or disease. The primary objective of the study is to evaluate the usability of the Novus system among these patients and to gain subjects' feedback regarding the device when used on a daily basis.The secondary objective is to obtain information about the performance of the system as a gait assistive device and to evaluate the subject's Quality of Life while using the system.

PET Imaging in ALS Patients
Amyotrophic Lateral Sclerosis (ALS)This is a pilot study to evaluate a potential imaging biomarker for aiding diagnosis and monitoring progression of ALS, based on a well established basic science pathway, published human autopsy data, preliminary data in ALS mutant mice, and our recently published data using brain PET scans to image the metabotropic glutamate receptor type 5 (mGluR5) in healthy human volunteers.
Supported Treadmill Ambulation Training (STAT) for Patients Diagnosed With Amyotrophic Lateral Aclerosis...
Amyotrophic Lateral SclerosisMotor Neuron Disease1 moreThe purpose of this study is to find out if supervised exercise training using a treadmill with partial weight support is safe and has an impact on gait and function of persons with Amyotrophic lateral sclerosis.
Study of Dopamine and Serotonin Transporters in Patients With Amyotrophic Lateral Sclerosis and...
Amyotrophic Lateral SclerosisThe purpose of this study is to study the transporters of serotonin and dopamine in ALS patients in relation with the clinical phenotype, i.e., patients without stiffness, patients with pyramidal stiffness, patients with mixed (pyramidal and extra pyramidal) stiffness. For such a goal the investigators will use SPECT to compare the binding of two specific tracers in ALS patients and in matched healthy controls.
