Comparison of Progressive Muscle Relaxation and Stretching Exercises in Diabetic Population

Primary outcomes

1. Heart rate variability

   Time frame: 24 hours

   It is a valuable tool in various fields, including health, fitness, and psychology for assessing the body's physiological responses. HRV is linked to emotional regulation and mental health, lower HRV is often associated with anxiety, depression, and other mental health conditions. In therapeutic settings, biofeedback using HRV can help individuals learn to manage stress and improve emotional resilience. HRV has been validated as a tool to measure autonomic nervous system activity, particularly the balance between sympathetic(stress) and parasympathetic (recovery) responses it is widely used in stress and fatigue research. HRV shows good test-retest reliability when measured under consistent conditions, such as in the same environment at the same time, of the day, and in the same position.

2. Cortisol levels

   Time frame: 24 hours

   Cortisol is a hormone released in response to stress, typically measured through saliva or blood samples. CL is used to monitor how well a patient is responding to treatment for conditions like adrenal disorders depression, or stress related illness. It can be measured through saliva, blood, urine, and hair being a common non-invasive method. Cortisol is widely regarded as a valid indicator of physiological stress. Cortisol is sensitive to external factors including stressors like physical exertion or even the experience of being tested. The reliability of cortisol as a measure of stress or health depends heavily on stress control.

3. Galvanic skin response

   Time frame: 24 hours

   GSR also known as electro-dermal activity, is a physiological measure of skin conductance that reflects changes in sweat gland activity. GSR measures the skin's ability to conduct electricity. When a person experiences emotional arousal, the (SNS triggers sweat glands, particularly on the palms and soles to become more active, this increases the skin's electrical conductance which the GSR sensor can detect. GSR is generally considered valid in measuring arousal or emotional intensity It is a good indicator of stress, anxiety, or excitement because these emotions typically involve a heightened autonomic nervous system.

4. Perceived stress

   Time frame: 2 weeks

   Perceived stress scale is a widely used psychological instrument designed to assess the perception of stress. It helps to measure the degree to which situations in one's life are appraised as stressful. It evaluates the subjective experience of stress. Which can vary significantly between individuals. Studies have confirmed that the PSS effectively measures perceived stress, a psychological state characterized by feelings of unpredictability and uncontrollability. The Perceived Stress Scale (PSS) scoring involves summing the responses to 10 questions, with higher scores indicating higher perceived stress levels. The scale uses a 5-point Likert scale, where 0 represents "never" and 4 represents "very often". Some questions are reverse-scored to account for coping mechanisms. Scores can range from 0 to 40, with ranges like 0-13 (low), 14-26 (moderate), and 27-40 (high) used for general interpretation
