Effects of Yoga on Phase Angle and Quality of Life in Patients With Breast Cancer

Study Overview
=================
Brief Summary
-----------------
In this study,we aimed to examine the effects of Hatha yoga on PA and QoL in patients with breast cancer. Patients will be randomized to receive the yoga group and the control group.Hatha yoga will be practiced twice a week for 10 weeks for intervention group.The PA of the patients will be assessed using a body analysis instrument and QoL was evaluated with an EORTC-Q questionnaire both before treatment and at week 10.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Yoga Group<br>Hatha yoga will be practiced twice a week for 10 weeks | Other: Yoga<br>* Each class started with a check-in period during which any questions or concerns could be raised, after which the patients were given 5 minutes for seated meditation and 10 minutes for Shavasana (lying down in a restorative position). The following poses were instructed during the course: standing poses with mountain pose (tadasana), chair pose (utkatasana), extended triangle pose (utthita trikonasana), extended side angle pose (utthita parshvakonasana), warrior 1 (virabhadrasana 1), warrior 2 (virabhadrasana 2) and tree pose (vrikshasana). The intervention was applied twice a week for 10 weeks.<br>|
| No Intervention: Control group<br>This group will not have any intervention. | |

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Phase Angle | Phase angle was evaluated with a Tanita body composition monitor (Tanita Corp., Tokyo, Japan). Electrodes are placed on both feet and both hands that send electrical signals from the body to a single independent unit. Voltages are measured at the top of the thumbs on both hands and both heels. A high-frequency electric current (90μA at 50 kHz) is applied, and the Resistance (R) and Reactance (xc) values are measured between the hands and feet. Internal software calculates the phase angle based on the following formula: Phase angle (PhA) = Reactance (xc) / Resistance (R) * (180 / π) | 10 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The European Organization for Research and Treatment of Cancer Quality of life (EORTC QLQ-C30) questionnaire | The European Organization for Research and Treatment of Cancer Quality of life (EORTC QLQ-C30) questionnaire; This 30-question survey is conducted to evaluate QoL in patients with breast cancer and assesses any symptoms that occurred in the previous two weeks. The questionnaires are divided into three scales: global health scale (GHS), functional scale (FS), and symptom scale (SS). High scores in the functional and global health scales indicate a good QoL, while high scores on the symptom scale point to a high level of problems | 10 weeks | 
| Arm Volume | Patients were also evaluated for the lymphedema of the limbs is assessed through circumferential and volumetric methods. Circumferential upper limb measurements were carried out with the arm abducted to 30°, starting at the level of the carpometacarpal joint, and at every 5 cm proximal to this point along with both limbs | 10 weeks | 
| Body-Mass Index | Body Mass Index is a simple calculation using a person's height and weight. The formula is BMI = kg/m2 where kg is a person's weight in kilograms and m2 is their height in metres squared. | 10 weeks |
