The inclusion criteria to participate in the study are being in a wheelchair, preserved cognitive status and having sufficient ability to Oral occlusion for carrying out respiratory tests. The exclusion criteria are following: presence of respiratory diseases or in treatment of respiratory diseases, serious orthopedic diseases that interfere with measurements and those with a diagnosis of dementia. In addition, those who present any contraindication for carrying out the procedure will be excluded.

of the respiratory pressure measurement tests, as established in the SEPAR guidelines. The objectives of the study and the methodology to be used will be explained to all participants.

An information sheet will be provided and the informed consent sheet will be given to them.

Sociodemographic dates

Clinical variables will be extracted from history clinic

Palm grip strength will be measured with the digital hand dynamometer (Jamar©). The Participants will remain seated with the shoulder in 0° adduction; elbow flexed 90° and forearm in neutral position. Three attempts will be made and the best value will be chosen

The 5STS test measures the time (in seconds) it takes a subject to stop 5 times from a sitting position, as quickly as possible.

The gait speed test (4MGS) measures the time it takes to cross a line of 4m at normal speed.

- The analysis of body composition will be carried out with the TANITA MC 780-P MA monitor, which provides information on visceral and body fat, skeletal muscle level, BMI and basal metabolism.

To measure respiratory muscle force, the maximum respiratory pressures will be evaluated in mouth (PIM/PEM). For them we will use an inspiratory and expiratory mouth pressure monitor maximum, a module of the Datapir touch© spirometer (Sibelmed, Barcelona). The measurement will be performed by a previously trained and experienced physiotherapist, following the protocol established by the Spanish Society of Pulmonology (4-SEPAR).

The health outcome variables that will be recorded over a year will be: infections respiratory diseases, visit to the emergency department, hospitalization, bedridden and/or death. This Information will be extracted from the patient's clinical record.
