About

Due to an early brain injury occurring in antenatal or postnatal, cerebral palsy (CP) causes alteration in motor function with posture and gait disorders. It is commonly observed motor performance degradation during adulthood, and the underlying pathophysiology remains poorly known.

Full description

One of the hypotheses to explain the decline in walking capacities in adults with CP is their greater fatigability, that could be related to energy overconsumption (due to the specific biomechanical constraints of their walking pattern) and/or the occurrence of early sarcopenia affecting the compensatory muscle mechanisms commonly seen in children to compensate for architectural disorders and posture alterations. To optimize prevention and/or therapy in these patients, it is crucial to better understand the aetiology of fatigability and its role in the decline in walking performance.

Patients with cerebral palsy

Experimental group

Description:

A specially adapted recumbent cycle ergometer with the ability to quickly transform into an isometric dynamometer will be used to assess fatigability development during a task to failure. Throughout the task, which consists of blocks of 3 minutes, neuromuscular assessments will take place to determine the evolution of fatigability and its peripheral and central determinants.

Other: Fatigability assessment
