Summary

this stuy tries to evaulate the best contraction (hold time) during isometric effort that can provide the best therapeutic effects on muscular performance in patients with knee osteoarthritis

Conditions

  • Knee Arthritis Osteoarthritis

Interventions

OTHER

isometric exercises

Isometric quadriceps exercise: Patients lie in a supine position. A rolled-up towel was put beneath the knee. They were instructed to maximally activate their thigh muscles to straighten their knee and hold the contraction for 5 seconds (Group A), 10 seconds (Group B), or 20 seconds (Group C).

OTHER

therapeutic ultrasound

all patients will reciece ultrasound for 5 minutes using 1MHz frequency, 0.8 wc2, 5cm2 head with adequate gel as a coupling medium

OTHER
