The investigators will calculate values of absolute and relative reliability for intrarater reliability when the measures are taken during a hemodialysis treatment day and during a non-dialysis day. Interrater reliability between two different observers will be also calculated
Patients suffering from End Stage Renal Disease are commonly involved in haemodialysis treatment, which is the most common treatment at this stage. Haemodialysis substitutes the renal function but is associated with several alterations that lead to decrease in functional capacity. Many studies show that functional capacity is significantly worse than their healthy sedentary age - matched counterparts. The purpose of the present study is to calculate values of absolute and relative intrarater reliability (dialysis vs non dialysis day) and interrater reliability of different physical function measures (Short Physical Performance Battery, one-leg balance, Timed Up and go, sit to stand to sit tests, triceps and handgrip strength, six-minute walking test).

Test-retest reliability of physical function in hemodialysis patients
Hospital de Terrassa
Terrassa, Barcelona, Spain
Change from baseline Short Physical Performance Battery at one week
Assess lower extremity, which includes objective performance-based measure of balance (side-by-side, semitandem and tandem), endurance (4m gait speed) and strength (five chair stands). Each component was scored from 0 to 4 and when summed yielded SPPB scores between 0 (poor) and 12 (best).
Time frame: It will perform the test three times with one week interval between the testing sessions, one before hemodialysis, and the other one next week during a non-dialysis day
Change from baseline Gait speed at one week at one week
Speed to cover 4 meters, in meters/second
Time frame: It will perform the test three times with one week interval between the testing sessions, one before hemodialysis, and the other one next week during a non-dialysis day
Change from baseline One-leg standing test at one week
Time achieved while standing on one leg
Time frame: It will perform the test three times with one week interval between the testing sessions, one before hemodialysis, and the other one next week during a non-dialysis day
Change from baseline Timed up and go at one week
Time to stand up, walk 3 meters, come back and sit down again
Time frame: It will perform the test three times with one week interval between the testing sessions, one before hemodialysis, and the other one next week during a non-dialysis day
Change from baseline Sit to stand 10 test at one week
Time to perform 10 repetitions sit to stand
Time frame: It will perform the test three times with one week interval between the testing sessions, one before hemodialysis, and the other one next week during a non-dialysis day

Change from baseline Sit to stand 60 test at one week
Sit to stand repetitions performed in 60 seconds
Time frame: It will perform the test three times with one week interval between the testing sessions, one before hemodialysis, and the other one next week during a non-dialysis day
Change from baseline One-leg heel rise test at one week
Number of heel rise repetitions achieved
Time frame: It will perform the test three times with one week interval between the testing sessions, one before hemodialysis, and the other one next week during a non-dialysis day
Change from baseline 6 minutes walk test at one week
Number of meters walked in 6 minutes
Time frame: It will perform the test three times with one week interval between the testing sessions, one before hemodialysis, and the other one next week during a non-dialysis day
Change from baseline Handgrip at one week
Bilateral handgrip strength
Time frame: It will perform the test three times with one week interval between the testing sessions, one before hemodialysis, and the other one next week during a non-dialysis day
