Reliability of Functional Measures in Hemodialysis Patient.
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.

The investigators pretend to calculate values absolute and relative reliability that have not been yet reported (Short Physical Performance Battery, one-leg balance and Timed Up and go).
Condition or disease
End Stage Renal Disease
Other: functional tests
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 and health related quality of life (HRQoL). Many studies show that functional capacity, physical activity level and HRQoL is significantly worse than their healthy sedentary age - matched counterparts. It is unknown if low physical activity, uraemia or anaemia are responsible for the decreased functional capacity of this cohort. Physical performance tests are frequently used to assess haemodialysis patients since is a feasible and low-cost evaluation. The purpose of the present study is quantified how the functional capacity changes over a -6 months period in a group of haemodialysis patients. Additionally the investigators pretend to calculate values absolute and relative reliability that have not been yet reported (Short Physical Performance Battery, one-leg balance and Timed Up and go).
Short Physical Performance Battery [ Time Frame: It will perform the test twice with one to two weeks interval between the testing session ]
Assess lower extremity, which includes objective performance-based measure of balance (side-by-side, semitanden 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).
Secondary Outcome Measures :
One Leg Standing Test [ Time Frame: It will perform the test twice with one to two weeks interval between the testing session ]
Consist in maintain one leg stance for as long as possible. The test was considered normal if the one leg standing time reached 45 seconds.
Timed Up and Go [ Time Frame: It will perform the test twice with one to two weeks interval between the testing session ]
To stand up from a standard arms chair, walk 3 meters, turn back the cone walk back and sit down to the chair. The time in seconds is record.
