• La vitesse de déplacement donne le meilleur pronostic de survie à 3 ans chez les patients atteints d’insuffisance rénale. Plus elle est lente, plus leur probabilité de décès est forte.

    To study the issue, Baback Roshanravan, MD MS (Kidney Research Institute, Division of Nephrology at the University of Washington) and his colleagues followed 385 patients with CKD [ chronic kidney disease, insuffisance rénale ] without a history of stroke or disability and with an average age of 61 years. The researchers compared handgrip strength, usual walking speed, six-minute walking distance, and timed up and go (the time that a person takes to rise from a chair, walk four meters, turn around, walk back to the chair, and sit down).

    Among the major findings during the average three-year follow-up period:

    Measures of lower extremity performance were at least 30 per cent lower than predicted, but handgrip strength was relatively preserved.

    Each 0.1-meter per second slower walking speed was linked with a 26 per cent higher risk for death over an average three-year follow-up period, and each one-second longer timed up and go was linked with an 8 per cent higher risk for death.

    Walking speed and timed up and go more strongly predicted three-year mortality than kidney function or common blood tests.
