Total knee arthroplasty TKA is a common surgery to help patients with advanced joint diseases improve mobility and quality of life. However, patients often face severe pain, limited movement, and changes in vital signs within the first 72 hours after surgery, which can slow recovery. This trial evaluates Reiki, a gentle, non-invasive therapy aimed at supporting the bodys natural healing by transferring energy, to see if it can reduce pain, improve movement, and stabilize vital signs after TKA. Participants will be randomly assigned to one of two groups a Reiki therapy group or a control group receiving standard postoperative care. The Reiki group will receive three Reiki sessions at 24, 48, and 72 hours after surgery, each lasting 30 to 45 minutes and delivered by a certified practitioner. Reiki is applied through gentle touch or hands held slightly above specific energy points on the body, including seven main centers and the knee and foot areas. The control group will receive routine care without Reiki. During the study, pain levels, mobility, and vital signs such as blood pressure, heart rate, and oxygen levels will be measured before and after each Reiki session at 24, 48, and 72 hours post-surgery. Researchers will also track the amount and timing of pain medication used by participants. The study aims to provide detailed information on how Reiki may support recovery after knee replacement surgery. Participation lasts for the first three days after surgery, with assessments conducted at specific intervals.

This research aims to evaluate the short-term effects of transcutaneous auricular vagus nerve stimulation taVNS, a non-invasive electrical stimulation applied to the outer ear, on lung function in healthy adults aged 18 to 40. The vagus nerve influences many automatic body functions, and this study investigates whether a brief stimulation session can acutely alter breathing test results in people without respiratory disease. Participants are randomly assigned to one of two groups active bilateral taVNS applied to ear regions connected to the vagus nerve, or a sham stimulation designed to mimic the procedure without activating the nerve. The stimulation lasts about 10 minutes during a single laboratory visit. Spirometry tests measuring forced vital capacity FVC, forced expiratory volume in one second FEV1, and peak expiratory flow PEF are performed immediately before and after stimulation. Heart rate, heart rate variability, and blood pressure may also be recorded for safety and physiological monitoring. During the visit, participants undergo spirometry and physiological measurements before and after the stimulation session. Researchers monitor for any side effects, which are usually mild and temporary, such as tingling or slight discomfort in the ear. Participants may withdraw at any time. The main outcomes focus on changes in lung function measurements between pre- and post-stimulation. Data analysis will compare these changes between the active and sham groups to understand whether short-term ear-based vagus nerve stimulation influences breathing test results.
