The Effect of Intradialytic Exercise on the Functional Capacity of Hemodialysis Patients
2014年3月19日 更新者:Dr Jennifer MacRae、University of Calgary
The purpose of this study is to explore the impact of an intradialytic exercise program on functional capacity, aerobic capacity, strength, quality of life, depression, hospitalizations and intradialytic episodes of hypotension.
The investigators would also like to look at the impact of exercise training over twelve weeks on hemoglobin levels as well as the clearance of potassium, phosphate and urea.
Our hypothesis is that the above mentioned outcomes will positively improve over the twelve week intervention.

武器和干预
参与者组/臂 |
干预/治疗 |
|---|---|
|
实验性的:intradialytic exercise
baseline data prior to starting exercise program will be obtained and then compared to the data after 12 weeks of an intradialtyic biking program
|
12 weeks of intradialytic biking at Borg intensity 3 - 4 for 15 to 60 minutes on each dialysis run

研究衡量的是什么?
主要结果指标
结果测量 |
措施说明 |
大体时间 |
|---|---|---|
|
Functional Capacity
大体时间:12 weeks
|
Functional capacity is measured by the DASI score which gives an estimated V02 peak in ml/min/kg.
The difference between the mean score at baseline and 12 weeks will be determined.
|
12 weeks
|
次要结果测量

措施说明 |
大体时间 |
|---|---|---|
|
Aerobic capacity
大体时间:12 weeks
|
Aerobic capacity is measured as a function of the DASI score
|
12 weeks
|
|
Strength
大体时间:12 weeks
|
Strength is determined as bilateral hand grip strength (measured in kg) as well as by the 30 second sit to stand test(the number of repetitions achieved in 30 seconds).
These measures are obtained at baseline and again at 12 weeks.
|
12 weeks
|
|
Quality of life
大体时间:12 weeks
|
The KDQOL- SF36 will be used to measure the quality of life at baseline and again at 12 weeks.
|
12 weeks
|
|
Hospitalizations
大体时间:12 weeks
|
The number and rate of hospitalizations will be determined prior to exercise start and during the 12 week exercise program.
Length of stay is also tracked.
|
12 weeks
|
|
Hypotension
大体时间:12 weeks
|
Intradialytic hypotension, defined as a drop in systolic blood pressure (SBP) of 20 mmHg for patients with pre-dialysis blood pressure > 100 mmHg or a drop in SBP of 10 mmHg for patients with pre-dialysis blood pressure < = 90 mmHg.
IDH with patient symptoms and nursing interventions will be obtained as well.
|
12 weeks
|
|
Hemoglobin levels
大体时间:12 weeks
|
The baseline hemoglobin and hemoglobin at 12 weeks will be tracked.
|
12 weeks
|
|
Potassium levels
大体时间:12 weeks
|
The baseline potassium and potassium at 12 weeks as well as the K gradient (pre -dialysis - dialysate K level)will be monitored.
|
12 weeks
|
|
Urea removal
大体时间:12 weeks
|
The baseline and 12 week pre and post dialysis urea levels will be monitored.
|
12 weeks
|
|
Phosphate levels
大体时间:12 weeks
|
The baseline and 12 week pre-dialysis phosphate levels will be tracked.
|
12 weeks
|
|
Bioimpedance derived volume and body mass determinations
大体时间:12 weeks
|
In a small subset of patients (n=10) the bioimpedance derived fluid compartments (ECF, ICF, E:I ratio) and fat free body mass will be determined at both baseline and 12 weeks.
|
12 weeks
