Effect of Combination Therapy on Knee Osteoarthritis Pain in Postmenopausal Women

Study Overview
=================
Brief Summary
-----------------
the aim of this study is to investigate the efficacy of Combination Therapy on Knee Osteoarthritis Pain in Postmenopausal Women

Detailed Description
-----------------
Osteoarthritis (OA) is the most common musculoskeletal condition affecting the quality of life of older adults. The prevalence of OA is very high 45% in females in comparison to males, especially after menopause due to the hormonal changes. In the physical therapy practice, therapeutic ultrasound (US) is one of the most frequently applied electrotherapeutic modalities in orthopedics physiotherapy. Simultaneous application of two therapeutic modalities at the same site is described as combination therapy (CT). The most commonly used CT is US & Transcutaneous neuromuscular electrical stimulation (TENS )where this approach was effective in pain modulation .The use of combination therapy is highly preferable because of the advantageous effect both electro-therapy and ultrasound provide simultaneously. There are no current studies on using combination therapy in the treatment of pain in mild to moderate knee osteoarthritis in post-menopausal women and we don't know the proper treatment dose.The study is designed as a prospective, randomized, pre-posttest, controlled trial.where we have two groups Intervention group and control. the intervention group will recieve strengthening exercises in addition to combination therapy 10 minutes for each session, 3 times per week, for 3 weeks.The Control group will recieve the same strengthening exercises as intervention group and sham combination therapy 10 minutes for each session, 3 times per week, for 2 weeks.
