Combined Kinetic Chain Exercises on Knee Osteoarthritis

Combined Open And Closed Kinetic Chain Exercises On Static And Dynamic Strength Of Hamstring And Quadriceps In Knee Osteoarthritis Patients

study will be conducted at faculty of physical therapy cairo university to investigate the effect of combined kinetic chain exercises on static and dynamic hamstring and quadriceps strength in knee osteoarthritis patients

the study will be conducted at faculty of physical therapy cairo university to investigate the effect of combined kinetic chain exercises on static and dynamic hamstring and quadriceps strength ,knee pain ,function ,H/Q ratio in knee osteoarthritis patients .using lafayette hand held dynamometer to measuring static strength of hamstring and quadriceps ,and free weight by Brzycki formula for measuring dynamic hamstring and quadriceps strength by determining 1 repetition maximum ,and pain measured by visual analogue scale (VAS) rating from (0 = no pain ) to (10= worst pain ) ,and function by Western Ontario and McMaster Universities Osteoarthritis Index questionnaire lower score indicate patient get better ,number of patients will be 34 divided into 2 groups ,each group will include 17 patient ,with 2 drop out according to sample size calculation ,each group will receive conventional tens for 20 min. and hot back for 15 min. and stretching exercises for hamstring,quadriceps,calf muscles ,while the experimental group will be increased by combined kinetic chain exercises
