Radiofrequency (RF) is the emission of high frequency waves via an applicator. The transfer of electromagnetic energy stimulates targeted tissues. RF can be used in two ways: capacitive or resistive ( Kumarane etal.,2015) This has been shown to increase vascularization and reduce inflammation and swelling and to accelerate the healing process and provide pain relief( Duñabeitia et al., 2018). It is used to provide rapid pain relief for sport injuries and allows quicker recovery [Duñabeitia etal, 2018& Weber T, Kabelka2011). low back pain and traumatology and urology (Notarnicola etal, 2017). The capacitive mode (CET) concentrates the energy to target soft tissues containing electrolytes: muscles, vascular or lymphatic tissues. The resistive mode (RET) targets denser tissues containing more fat and fiber (such as bones, ligaments and tendons). High frequency waves penetrate deep into tissues and increase both exchanges and temperature and a recent study has demonstrated the effects of RF on the skin microcirculation and the intramuscular blood flow (Kumaraane et al., 2015). To date, no study has evaluated the impact of TECAR treatment on rectus diastasis in postnatal women This study will be carried out on 30 postnatal females suffering from diastasis recti more than 2.5 cm with bulged abdomen, they will be selected from out patient physical therapy clinic, kafr el sheikh university. Their age ranged from 25 - 35 years. Their body mass index (BMI) ranged from 25-35 kg/m2. All women delivered normally~Exclusion criteria:~Any participant was excluded if she had any disease that interferes with exercises (asthma), any skin disease or sensitivity that interferes with the application, any chest disease or cardiac disease or women had abdominal or surgery.~All participants will read an explanation of the experimental procedures and sign an informed consent that is approved by the Ethical committee Institutional Review Board, Faculty of Physical Therapy, kafr elsheikh University, Egypt This study will be a randomized, double-blind, pre test-post test crossover trial with control group. The randomization procedure will be performed by a simple drawing of lots (A or B) which determined whether participants would receive the TECAR therapy and abdominal exercises ( group A) and abdominal exercises only in (group B). The randomization procedure will be performed through a computer program (Microsoft Excel 2010) that created a random table of numbers in which each number corresponded to the group A or B. After that, participants will be allocated according to the corresponding number of their allocation code. A researcher will be conducted the drawing procedures without informing participants and evaluators, to determine which will be in group A or group B. Thus, both participants and evaluators will be blinded to the allocation of treatment.~Study group (Group A):~It was consisted of 15 post natal women who will performed weight reduction diet ( 1200 kcal/day) , TECAR application and selected abdominal exercises program that consists of static abdominal and posterior pelvic tilting~Control group(Group B):~It was consisted of 15 postnatal women who was performed weight reduction diet (1200 kcal/day) and selected abdominal exercises and posterior pelvic tilting exercises.
The study aim to evaluate the impact of TECAR treatment on rectus diastasis in postnatal women
