Brief Summary:

This study will be conducted over a 3 year time period. This is a trial of an exercise intervention vs. standard of care in patients receiving chronic dialysis. The specific aims will be to determine feasibility of patient recruitment, adherence to the exercise program, and efficacy of the intervention on patient important outcomes.

The exercise intervention will be delivered to randomized participants for 12 months, and consist of the prescribed use of Nordic Walking poles, online resources for exercise in the home, regular use of a pedometer to monitor progress, and regular verbal encouragement to exercise (monthly) by dialysis unit staff. Both groups will receive the same standard of care co-interventions including individualized dialysis prescriptions and health-care interactions according to practices at their centre.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 90 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Simple Exercise Program for Patients With End Stage Kidney Disease to Improve Strength and Quality of Life: A Feasibility Study
Actual Study Start Date : April 15, 2019
Estimated Primary Completion Date : September 15, 2023
Estimated Study Completion Date : September 15, 2024

Arm Intervention/treatment
Experimental: Exercise Intervention
Participants in this arm will receive standard of care along with the exercise prescription intervention
Behavioral: Exercise Prescription

Participants in the intervention group will be given an exercise prescription to increase their baseline steps by 1200 and 2000 steps per day at least 3 days a week over the first 3 months. If tolerated and accepted, the participants will increase their step counts by an additional 600 to 1000 steps per day at least 3 days a week for the next 3 months.This will be followed by a 6-month maintenance phase. The research coordinator will instruct the participants on the proper use of the Nordic walking poles which can be used to help participants achieve their prescribed number of steps.

All participants will be encouraged to wear the pedometer throughout the trial in order to follow the step-count prescription and monitor adherence.

No Intervention: Standard of Care
This group will receive standard of care treatment including regular verbal encouragement to exercise (monthly) by dialysis unit staff.

Primary Outcome Measures :
  1. Recruitment Feasibility [ Time Frame: 30 months ]
    The investigators will assess at each centre the number of participants receiving dialysis, approached for participation, eligible to participate and any reasons for non-participation.

  2. Adherence [ Time Frame: 12 months ]
    Two-week step counts with a pedometer will be monitored monthly in the treatment group, and at baseline, 6 and 12 months in the control group.

Secondary Outcome Measures :
  1. Hand Grip Strength [ Time Frame: 12 months ]
    The investigators will measure hand grip strength at baseline, 6, and 12 months using a handgrip dynamometer in the dominant hand or in the non-arteriovenous fistula arm (best of two efforts in kgs)

  2. Quality of Life using Vitality Subscale [ Time Frame: 12 months ]
    Energy will be measured with the Medical Outcomes Study 36 Item Short Form Survey Instrument - Vitality Subscale (Score 0 (lowest) -100 (highest, more energy)

  3. Sleep Quality [ Time Frame: 12 months ]
    Sleep will be measured with the Pittsburgh Sleep Quality Index (Score 0-21; lower scores reflect better sleep).

  4. Hospitalizations [ Time Frame: 12 months ]
    The number of hospitalizations per patient year

  5. Hospital Length of Stay [ Time Frame: 12 months ]
    Average number of days spent in hospital

  6. Change in Living Status [ Time Frame: 12 months ]
    Including full care (admission to a long-term care facility), need for assistance such as housekeeping, meals, bathing

  7. Safety of the Exercise Program [ Time Frame: 12 months ]
    Safety will be measured by monitoring serious adverse events
