Brief summary
The evolution of chronic kidney disease (CKD) causes a systemic upheaval on the body and a deep fatigue is very often described by patients (50-70% of the patients) even before the start of dialysis (pre-dialysis). This fatigue has many origins, and one of them probably stems from a deterioration of neuromuscular abilities. Very few studies have examined the physiological aspects of neuromuscular fatigue in pre-dialysis patients, and shedding light on potential deficits at this level would allow safe and efficient implementation of adapted physical activity programs. Our study aims to characterize the pathophysiology of neuromuscular capabilities in chronic advanced renal failure in pre-dialysis patients.
Interventions
DIAGNOSTIC_TESTDiscrimination of neuromuscular alterations protocol
Patients will perform a hand grip fatigability test with their dominant hand, followed by a Timed Up and Go Test (TUG-Test), a Five-repetition sit-to-stand-test (5STS-Test) and a10 meters gait speed test.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Neuromuscular evaluation of force. | 1 day | Maximum force normalized by body mass, measured by a hand grip test with the dominant hand. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Psychometric evaluation of fatigue | 1 day | The Multidimensional Fatigue Inventory (MFI) is a 20 question self-report instrument designed to measure fatigue. It covers the following dimensions: General Fatigue, Physical Fatigue, Mental Fatigue, Reduced Motivation and Reduced Activity. Each question is graded from 1 ("Yes, that is true") to 5 ("No, that is not true"). Higher scores indicate a higher level of fatigue. |
| Quality of life impact of fatigue | 1 day | The functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) evaluates the impact on quality of life of chronic illness. This is a questionnaire with 13 questions graded according to a Likert scale ranging from 1 to 5 (1 = quite, 5 = not at all). |
| Assessment of gait and balance | 1 day | The Timed Up and Go test (TUG) is a simple test used to assess a person's mobility and requires both static and dynamic balance. It measures the time that a person takes to rise from a chair, walk three meters, turn around, walk back to the chair, and sit down. |
| Assesment of lower limb functional strength | 1 day | The five-repetition sit-to-stand test (5STS) is a test of lower limb function that measures the fastest time taken to stand five times from a chair with arms folded. |
| Assesment of walking speed | 1 day | 10 meters gait speed test: measure of the time required to walk 10 meters at the fastest speed possible. |
| Electromyographic evaluation: temporal recruitment of the motor units. | 1 day | The evolution of temporal recruitment through the evaluation of the discharge frequency of the motor units. |
| Electromyographic evaluation: Root Mean Square measurement | 1 day | The average Root Mean Square (RMS) evolution according to the progress of the fatigability protocol, and its link with the developed force. |
