What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Physical Activity
Time Frame: Baseline and 12 weeks
change in steps per day from pedometer
Baseline and 12 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Physical Performance
Time Frame: Baseline and 12 weeks
change in score on the Short Physical Performance Battery (0-12), higher scores indicate greater physical performance
Baseline and 12 weeks
Self-reported Physical Functioning
Time Frame: Baseline and 12 weeks
Change in score on the Physical Function scale of the Short-Form 36 Health Survey (scale from 0-100, higher numbers indicate better physical functioning)
Baseline and 12 weeks
Change in Activities of Daily Living Score
Time Frame: Baseline and 12 weeks
Barthel's Index of Daily Activities (Index range 0-20, higher scores indicate greater functional independence)
Baseline and 12 weeks
Change in Symptom Burden on the Dialysis Symptoms Index
Time Frame: Baseline and 12 weeks
Dialysis symptom index (symptom burden ranges from 0 - 29 symptoms experienced)
Baseline and 12 weeks
Change in Total Body Muscle Mass (Adjusted by Height Squared)
Time Frame: Baseline and 12 weeks
(TBMM calculated from measurements of intracellular water from bioimpedance spectrometry)
Baseline and 12 weeks
Change in Endothelial Function
Time Frame: 12 weeks
Reactive hyperemia index (RHI) using peripheral arterial tonometry. RHI is a non-invasive measure of endothelial function, measured using the EndoPAT 2000 (Itamar Medical). The pulse amplitude in the middle fingers of both hands was recorded for five minutes. A blood pressure cuff was then inflated in one arm (which did not have a vascular access in place) to at least 60 mmHg above systolic blood pressure to achieve full occlusion (minimum 200 mmHg, maximum 300 mmHg). After occlusion for 5 minutes, the cuff was deflated, and the device recorded changes in pulse amplitude for an additional 5 minutes and calculated RHI as the ratio of the post to pre occlusion amplitude of the occluded arm relative to the post to pre occlusion amplitude of the control arm, corrected for baseline vascular tone.
12 weeks
Change in the Short From 36 Vitality Scale
Time Frame: Baseline and 12 weeks
Short Form 36 Vitality Scale (0-100, greater values indicate increased levels of energy/decreased levels of fatigue)
Baseline and 12 weeks
Change in SDNN (ms)
Time Frame: 12 weeks
Standard deviation of N-N intervals as recorded on electrocardiography waveform (ms)
12 weeks
Change in Symptom Severity on Dialysis Symptoms Index
Time Frame: Baseline and 12 weeks
Symptoms range from score of 0 (Not at all bothersome) to 5 (Very Bothersome) over 29 symptoms. Score ranges from 0 - 145
Baseline and 12 weeks
