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

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| conventional group | Active Comparator | patients take conventional trans cutaneous electrical stimulation (tens) with a frequency of 100 Hz , a pulse duration of 60 micro seconds for 20 min. ,hot backs for 15 min,stretching exercises for hamstring ,quadriceps ,calf muscles |
|
| interventional group | Experimental | patients take conventional tens with a frequency of 100 Hz , a pulse duration of 60 micro seconds for 20 min. ,hot backs for 15 min,stretching exercises for hamstring ,quadriceps ,calf muscles with combined kinetic chain exercises (terminal knee extension,semi squat (wall slide) ,foreword step up and down ,straight leg raise ,seated knee extension ) |

| Hamstring /Quadriceps ((H/Q) ratio | dividing static hamstring on static quadriceps strength and dynamic hamstring on dynamic quadriceps strength | Evaluation will be performed prior to the first treatment session ;as a baseline measure,and at last treatment session (after 4 weeks) as a post -treatment measure |
| Measure | Description | Time Frame |
|---|---|---|
