Full description

Ⅰ-Subjects:

o Sixty-nine adult patients from both sexes. They were suffering from ESRD on maintenance hemodialysis, their age ranged from50-60 years old were selected from hemodialysis unit at Itay El Baroud central hospital. They were referred by the physician.

Study group (A): the study group consisted of (23) patients who received aerobic exercise in form of (foot pedal exerciser) for 20 Minutes for each session, 3 sessions per week, for 8 weeks plus maintain on their medical treatment and hemodialysis.

Study group (B): the study group consisted of (23) who received active free range of motion exercise (open kinetic chain active free range of motion) for 20 minutes for each session, 3 sessions per week, for 8 weeks plus maintain on their medical treatment and hemodialysis.

Control group (C): the control group consisted of (23) patients who were maintained on their medical treatment and hemodialysis.

II- Instrumentation 6-Minutes walk test: The 6-min walk test (6MWT) is frequently used to measure physical function in transplanted patients.

• Fatigue Questionnaire (Fatigue Severity Scale) it was used to assess the level of fatigue.
• Laboratory investigation: urea and creatinine are commonly used to monitor the effects of exercise on urea clearance and kidney function improvement in transplant patients.
• The Mini-Cog test: is a quick, simple, and effective screening tool for early cognitive impairment in hemodialysis patients, making it ideal for busy clinical settings.

B-Therapeutic Equipment:

Foot pedal exerciser (fig.9):

• Simple horizontal foot pedal exerciser used during hemodialysis sessions.
• Dual pedals with non-slip straps for foot stability.
• Manual resistance adjustment via a single control knob (non-electric).
• Provides gradual increase in workload intensity.
• Compact and light weight design suitable for use while lying on the dialysis bed.
• Enables controlled, low-impact circular movement of the feet.
• Aims to improve circulation and strengthen lower limb muscles without requiring active sitting.
• Approximate device dimensions: 50 cm (length) x 40 cm (width) x 23 cm (height).
• Maximum recommended user weight: 70 kg. Participants completed the 30-min aerobic exercise sessions during the first 2 hrs. of each dialysis session, 3 times per week for 8 weeks, using a simulated bike riding. Patients will perform active free exercise for upper limb (the arm that hasn't shunt) and lower limbs. Each exercise session consisted of three phases: warm up, conditioning, and cool down.

Enrollment: 69 estimated patients

Ages: 50 to 60 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

All patients were included according to the following criteria:

1. Age between 50-60years.
2. The patients had been on hemodialysis for at least 3 months with three sessions per week for 3-4hr per session.
3. The patients were diagnosed with end stage renal failure (stage5 CKD) on maintenance regular HD (three sessions/week (on alternate days), for four hours/session) for more than three months. (Receiving HD through uncomplicated arm arteriovenous (A-V) fistula
4. Under medical control
5. Both men and women were enrolled
6. Body math index ranged from 18,5- 24.9 kg/m²

Exclusion criteria

Patients who experienced or had one or more of the following were excluded from the study:

1. Patients with resting systolic blood pressure >200 mmHg and/or diastolic blood pressure >120 mmHg.
2. patients with neurological problems (e.g. stroke, head injury)
3. patients with musculoskeletal problems (e.g. sever osteoarthritis or difficulties in ambulation)
4. Patients with uncontrolled pulmonary disease. (e.g. exaggerated chronic obstructive pulmonary disease, acute asthma)
5. Patients with mental health problems and cognitive impairment due to inability to teach them how to make respiratory training.
6. Any patient who missed more than two weeks of the program or want to terminate the program.
7. Severe obesity (BMI >35)
8. Presence of malignant disease.
9. Patients with unstable angina, uncontrolled cardiac arrhythmia, decompensated heart failure, acute pericarditis or myocarditis.
10. The patients had hearing impairment or mental disorders.
