The goal of this clinical trial is to determine whether osteopathic manipulative treatment (OMT) enhances immune system readiness in healthy adults compared to exercise or sham light treatment. Specifically, the goal of this study is to assess circulating immune cells and signaling molecules in the blood in response to these various treatments.
It aims to compare: Complete Blood Counts (CBC) and blood immune signaling molecule levels in healthy adults in response to OMT, sham light touch, and exercise, with measurements taken at multiple time points.
Researchers will compare immune blood cells and signaling molecules in response to OMT versus sham light touch and exercise within the same group of healthy adults measured at three time points for each of the three total visits.
Participants will do a 15-minute OMT session, a 15-minute light sham session, or a 15-minute exercise session at each of their three separate visits (they will do one of each over the course of their 3 appointments in random order). They will have three blood draws taken at each of those three visits. They will also fill out a Global Physical Activity Questionnaire (GPAQ) survey to assess their level of physical activity throughout the study.
This clinical trial is a follow-up on a recent trial demonstrating an enhanced immune response in participants who received lymphatic osteopathic manipulative treatment (OMT) with each of their COVID-19 mRNA vaccinations. Similar immune enhancement was observed in a pilot study with OMT in conjunction with the Hepatitis B vaccine. Additionally, animal studies have shown that lymphatic pump OMT can cause transient increases in the movement of lymphatic fluid, immune cells, and signaling molecules throughout the body and bloodstream. These findings were further supported by in vitro studies on fibroblasts, where OMT led to significant increases in circulating cytokines. There are studies that suggest that combining physical exercise with vaccination can also improve immune responses. To parse out these effects observed in OMT and exercise studies and provide the mechanisms underlying the observed immune enhancements, this clinical trial will be conducted.
This study is designed as a crossover, self-controlled, comparative effectiveness randomized clinical trial. A total of 30 healthy individuals who meet all inclusion/exclusion criteria will be recruited. Participants will then fill out a health questionnaire during the screening process to confirm their eligibility.
Each participant will be randomly assigned to one of three intervention sequences to maintain blinding and control for order and sequencing effects. The intervention sequences are as follows:
There will be a 3-week washout period between each intervention. Participants will complete the Global Physical Activity Questionnaire (GPAQ) survey to identify their current level of exercise at each visit. They will also be monitored for any adverse effects following each intervention.
All treatment protocols will be done for a 12-minute timeframe per session. Participants will have three blood draws at each visit: at baseline, five minutes after intervention, and four hours after intervention. The primary outcome measures will include cytokine levels and circulating leukocyte levels, which will be compared across the different intervention sequences.
This study aims to provide a deeper understanding of the mechanism by which lymphatic OMT alters the immune system. It will also compare these effects to the mechanisms of exercise.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

A full standardized lymphatic protocol will be performed, including thoracic inlet left and right, thoracoabdominal release, pelvic diaphragm release, pedal pump, splenic pump, and abdominal lymphatic pump. This treatment will be done by systematically working down and back up. The protocol will last a total of 12 minutes for each participant
A full standardized 12-minute session in which treaters will mimic various osteopathic manipulative techniques at specific anatomical locations without applying pressure or manipulation.
A full standardized moderate-intensity physical activity as defined by the Centers for Disease Control (CDC). Target heart rate for moderate-intensity exercise should be between 64 and 76% of maximum heart rate. To estimate age-related heart rate, subjects' age will be subtracted from 220. Then, that number will be multiplied by 75%, which will be standardized across all subjects in the study. Heart rate will be monitored with the use of an attached pulse-ox monitor. Treadmill speed will be adjusted accordingly so that each subject maintains a heart rate of 75% of their maximum heart rate. A brisk walk will be done on a flat treadmill and no incline will be utilized. Subjects will be allowed a minute of warm-up to get to the appropriate pace/target heart rate.
Complete Blood Count (CBC) with differential
CBC with differential will be evaluated to identify the number of circulating plasma leukocytes for each intervention for each of the three interventions at three time points for each visit/intervention. This test will help us identify levels of erythrocytes, platelets, and leukocytes, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils. This will be compared across time points for OMT, sham treatment, and exercise.
Time frame: Baseline to 5 minutes post-intervention to 4 hours post-intervention.
Pro-Inflammatory cytokine profiling
V-Plex Human Proinflammatory Panel I (4-Plex) will be used to identify cytokine profiles, including including IL-6 (Interleukin-6), IL-1β (Interleukin-1 beta), INF-γ (Interferon-gamma), and TNF-α (Tumor Necrosis Factor-alpha). This will be evaluated for each of the three interventions at three time points for each visit/intervention. This will be compared across time points for OMT, sham treatment, and exercise.
Time frame: Baseline to 5 minutes post-intervention to 4 hours post-intervention.
Evaluation of safety based on reported adverse events
Documentation of any adverse events to OMT, sham treatment, or exercise protocol.
Time frame: Through study completion, an average of 6 weeks.
