CRN Meeting November 2010
Objectives

To provide knowledge and supporting data on benefits of
intradialytic exercise

To encourage incorporating exercise into routine patient
care plan

To provide information on beginning a unit based
exercise program

To describe the procedures and operations of a current
unit based exercise program
Physical Functioning

The ability of an individual to perform
activities required in their daily lives.

PF of dialysis patients is LOW!

Measures of Physical Functioning

Short Physical Performance Battery
• Gait speed (4 meters)
• Sit to stand (time for 5 )
• Standing balance tests

Other measures
• 6 min walk test

Physical Inactivity leads to…
Overall decline in physical well-being
Poor physical performance
Fluid build up in tissues
Loss of bone strength
Loss of appetite
Muscle wasting
Hypertension
Dependence
Fatigue
Relationship between sedentary behavior/low
CRF and higher mortality among patients with
ESRD

Maintenance of independence
Clearance

During dialysis:
• Urea removed from blood
• Urea retained in peripheral body
compartments
• Urea and creatinine distributed in body water
• Muscle water content high
• Muscle mass = ~40-45% total body weight
• Much of solute mass will be held within muscles
• Some body tissue is unexposed to dialysis

Clearance

After dialysis:

With exercise:
• Urea re-equilibrates and a rebound results
• Limits the efficiency of dialysis
• Muscle blood flow increases
• Potential increase from 3-4ml/min per 100g to
80ml/min per 100g
• More tissue mass is exposed to the
dialysis treatment
4. Kong, et al: Nephrol Dial Transplant. 1999; 14: 2927-2931.
Improved urea Kt/V with exercise

Surgeon General’s report:
“significant health benefits can be obtained
by including a moderate amount of
physical activity….on most, if not all,
days of the week”.

Medicine (ACSM)

Exercise is MedicineTM

Guiding principles:
•
•
•
Exercise and physical activity are important to health
and the prevention and treatment of many chronic
diseases
More should be done to address physical activity and
exercise in healthcare settings
ACSM and AMA are making efforts to bring a greater
focus on physical activity and exercise in healthcare
settings

Steps to developing an exercise
program



Gaining staff support
• Edu/inservice
• Case presentations
Commitment to developing a program
• Group input
• Assurance of willingness of staff to participate
Assess available resources
• Staff interest
• Teamwork
• Interested patients
• Local programs
6. Carlson L, Carey S. ACKD, 1999
Steps to developing an exercise
program



Develop a program
• Smaller working groups (care planning,
motivation/education, exercise programming)
• Staff responsibilities identified
• Facilitate a sense of ownership amongst staff
Start program
• Start slowly (one shift, one bay, interested pts)
• Progress gradually
Ongoing evaluation
• CQI
• Patient reassessment
6. Carlson L, Carey S. ACKD, 1999
• Patient programs
