Comparison of the effect of anaerobic strengthening exercises and aerobic exercise (walking) on the balance of patients with knee osteoarthritis.
Design
40 patients with knee osteoarthritis who are referred to the centers of physical therapy in Semnan University of Medical Sciences are selected.
Settings and conduct
This study was conducted on women with knee osteoarthritis referred by physicians to Semnan Medical Sciences Physiotherapy Centers. Patients were randomly assigned into two groups of aerobic and strengthening exercises. The intervention will take place for 4 weeks.Before and after the intervention, the static and dynamic balance will be measured and comparison will be made between the two groups.
Participants/Inclusion and exclusion criteria
Inclusion criteria:
1- Having unilateral or bilateral primary osteoarthritis
2-At least 40 years of age up to 60 years
3-Pain when sitting, standing or climbing stairs
4-Gaining pain equal to or greater than 3 in 10 in the VAS scale
Exclusion criteria:
1- Inability to walk
2- The condition of orthopedic or musculoskeletal and uncontrolled heart and 3- respiratory diseases affecting walking.
4- Previous neurological conditions that affect the strength and balance of the lower limbs and walking.
5- cold or ear infection in recent months
6- History of lower limb joint replacement
7- Severe obesity
Intervention groups
All patients are treated with therapeutic, 3 times a week for 4 weeks including continued ultrasound therapy, transcutaneus nerve electical stimulation and hot pac. Before starting exercise training, all subjects are asked to perform warm up exercise on ergonomic bicycle for 5 minutes.
strengthening exercises group: Strength training protocol included flexion and extension exercise of the knee joint utilizing a Quadriceps chair. each exercise sessions included 3 sets with 2 minutes intervals. The load of exercise increased progressively from 60 to 65 of 10 RM in the first, 70 20 75% of 10 RM in the second and 80 to 85% of 10 RM in the third. The amount of 10 RM are assed every week for each participants.
Aerobic exercise: The patient walk on tredmill for 50% to 85 % of the maximum heart rate for 40 minutes.The maximum heart rate during walking depending on the patient's tolerance, will increase gradually. To cool down, five minutes of walking will be done at a low speed.
