Intrarater and Interrater Reliability Physical Function Measures in HD BCN

Intrarater Reliability in Different Days and Interrater Reliability of Physical Function Assessment in HD Patients

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).

Inclusion Criteria:

• At least 3 months in hemodialysis treatment
• Clinically stable

Exclusion Criteria:

• Recent cardiac events (less than 3 months)
• Unable to exercise
