Back massage or back care involves cleaning and massaging an individual's back for therapeutic and comfort purposes. It increases elimination through the skin, induces sleep, provides comfort, regulates body temperature, and aids in patient observation. Contraindications include burns, rib fractures, spinal injuries, and back surgeries. Back massage techniques include effleurage, petrissage, friction, hand over hand strokes, brush strokes, kneading, and tapping motions. Proper back care involves assessing the skin, washing with soap and water, applying lotion or oil, massaging for 3-5 minutes, redressing the patient, and documenting the procedure.
