About

Both extra corporeal shock wave and dexamethasone iontophoresisare effective in treatment of knee osteoarthritis but which one is more effective is not clear yet . so the purpose of this study was to investigate and compare between the effect of shock wave and iontophoresis in treatment of knee osteoarthritis . it was hypothesized that there will be no difference between the effect of shock wave and iontophoresis on treatment of knee osteoarthritis.

Full description

60 subjects with grade II knee osteoarthritis will be recruited from outpatient clinic of faculty of physical therapy and then they will be assigned randomly by sealed envelope into three groups ;group A (shock wave group) will received radial extracorporeal shock wave ,group B (Iontophoresis group ) will receive deaxamthasone iontophoresis and group c (control group) will receive traditional tratment ( stregnthening exerciseces) all treatment will be once session per week for four weeks .pain intensity ,knee ROM and knee injury and osteoarthritis outcome score physical function short (KOOS-PS).

Enrollment: 60 patients

Sex: All

Ages: 40 to 55 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

---

60 participants in 3 patient groups

Shock wave(A)

Experimental group

Description:

subjects will recive radial extracorporeal shock wave (2000 shock/session, 10Hz and EFD 0.178 mJ/mm²) on knee joints once per week for four weeks in addition to strengthening exercise

Treatment:

Device: radial extracorporeal shock wave

Other: Exercise

Iontophoresis (B)

Experimental group

Description:

subjects will recive dexamethasone iontophoresis on knee joints once per week for four weeks in addition to strengthening exercise

Treatment:

Device: iontophoresis

Other: Exercise

Control (C)

Other group

Description:

stregnthening exercise;straight leg raising exercisein which the patients were positioned in the crook lying position with the unexercised limb was the flexed one then the patients were asked to contract the quadriceps muscle and elevate the limb to 45º and hold for 6 seconds, slowly lower the limb and then relax for 6 seconds, three sets of 10 repetitions were don ,Isometric quadriceps contraction (quadriceps drill) in full knee extension maintained for 5 seconds, followed by a 5-second rest; the exercise was performed for 20 repetitions per session .treatment once per week for four weeks

Treatment:

Other: Exercise
