Autogenic training is a form of self-relaxation therapy that was developed by the German psychiatrist Johannes Heinrich Schultz in the early 20th century. It involves the use of simple exercises to bring about a state of deep relaxation and mental calmness, with the goal of reducing stress and promoting overall well-being.

During autogenic training, individuals focus on their own physical sensations, such as warmth, heaviness, and relaxation, in order to induce a state of deep relaxation. This is often accomplished through the use of visualization techniques and guided imagery, as well as repetition of simple phrases or statements that help to reinforce the desired mental and physical states.

Autogenic training has been shown to be effective in reducing symptoms of anxiety, depression, and stress-related disorders, as well as improving sleep quality and overall quality of life. It is often used as a complementary therapy alongside traditional medical treatments, and can be practiced by individuals on their own or under the guidance of a trained therapist.

Biofeedback is a psychological and physiological intervention that involves the use of electronic devices to measure and provide real-time feedback to individuals about their bodily functions, such as heart rate, muscle tension, skin conductance, and brain activity. The goal of biofeedback is to help individuals gain awareness and control over these functions, with the aim of improving physical and mental health outcomes.

In psychology, biofeedback is often used as a treatment for a variety of conditions, including anxiety, stress, headaches, chronic pain, and mood disorders. By learning to regulate their physiological responses through biofeedback training, individuals can reduce symptoms and improve their overall well-being. The process typically involves working with a trained healthcare provider who guides the individual in practicing various relaxation techniques, such as deep breathing or progressive muscle relaxation, while monitoring their physiological responses using biofeedback equipment. Over time, the individual learns to associate these techniques with positive changes in their body and can use them to manage symptoms on their own.

Postural drainage is a medical technique that uses gravity to help clear secretions from the airways. It involves positioning the body in various ways to promote the flow of mucus or other fluids from the lungs, sinuses, or middle ear into the upper airway, where they can be more easily cleared by coughing or suctioning. This technique is often used in patients with respiratory conditions such as cystic fibrosis, bronchiectasis, and pneumonia to help improve lung function and reduce the risk of infection. It may also be used in patients with chronic sinusitis or middle ear effusions to promote drainage and relieve symptoms. The specific position used during postural drainage depends on the location of the secretions within the airway and may involve elevating the head, trunk, or legs, or turning the body to one side.
