Effects of Yoga on Phase Angle and Quality of Life in Patients With Breast Cancer: A Randomized, Single-blind, Controlled Trial

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Description

Inclusion Criteria:

  • Patients between the ages of 18 and 70, witha diagnosis of breast cancer

Exclusion Criteria:

  • Patients with recurrent or progressive disease, or with serious heart or pulmonary disease, with uncontrolled hypertension, infection, cognitive function disorder, psychiatric disease or musculoskeletal system conditions that would prevent exercise, and those who had taken part in a regular exercise program

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Yoga Group
Hatha yoga will be practiced twice a week for 10 weeks
Other: Yoga

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.
No Intervention: Control group
This group will not have any intervention.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Phase Angle
Time Frame: 10 weeks
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

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The European Organization for Research and Treatment of Cancer Quality of life (EORTC QLQ-C30) questionnaire
Time Frame: 10 weeks
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
Time Frame: 10 weeks
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
Time Frame: 10 weeks
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.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
