What researchers measure

Primary outcomes

  1. Physical Activity

    change in steps per day from pedometer

    Time frame: Baseline and 12 weeks

Secondary outcomes

  1. Physical Performance

    change in score on the Short Physical Performance Battery (0-12), higher scores indicate greater physical performance

    Time frame: Baseline and 12 weeks

  2. Self-reported Physical Functioning

    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)

    Time frame: Baseline and 12 weeks

  3. Change in Activities of Daily Living Score

    Barthel's Index of Daily Activities (Index range 0-20, higher scores indicate greater functional independence)

    Time frame: Baseline and 12 weeks

  4. Change in Symptom Burden on the Dialysis Symptoms Index

    Dialysis symptom index (symptom burden ranges from 0 - 29 symptoms experienced)

    Time frame: Baseline and 12 weeks

  5. Change in Total Body Muscle Mass (Adjusted by Height Squared)

    (TBMM calculated from measurements of intracellular water from bioimpedance spectrometry)

    Time frame: Baseline and 12 weeks

  6. Change in Endothelial Function

    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.

    Time frame: 12 weeks

  7. Change in the Short From 36 Vitality Scale

    Short Form 36 Vitality Scale (0-100, greater values indicate increased levels of energy/decreased levels of fatigue)

    Time frame: Baseline and 12 weeks

  8. Change in SDNN (ms)

    Standard deviation of N-N intervals as recorded on electrocardiography waveform (ms)

    Time frame: 12 weeks

  9. Change in Symptom Severity on Dialysis Symptoms Index

    Symptoms range from score of 0 (Not at all bothersome) to 5 (Very Bothersome) over 29 symptoms. Score ranges from 0 - 145

    Time frame: Baseline and 12 weeks

Limitations and caveats
Outcomes reported are median change within groups with 95% confidence interval. Primary analysis is difference in change between groups using linear mixed modeling. Participants were selected only from dialysis clinics in Northern California.
