Why reaction time matters
Reaction time is a direct measure of how efficiently your brain and body communicate. Whether you’re catching a ball, avoiding a fall, or reacting to visual or auditory cues, every split second counts. Chiropractic research led by Dr Heidi Haavik has shown that spinal adjustments can influence brain processing speed and motor control, improving the efficiency of neural communication.
What the research explored
In a series of neurophysiological studies, Haavik’s team investigated how chiropractic adjustments affect somatosensory processing and motor response times. By recording brain activity through EEG and measuring physical reaction time, the researchers evaluated whether restoring normal spinal joint motion could enhance neural integration.
Key findings
- Following a single chiropractic adjustment, participants showed a significant decrease in reaction time during sensorimotor tasks.
- Changes were accompanied by measurable alterations in cortical activity, suggesting enhanced brain–body communication.
- Improvements occurred without practice or learning effects, indicating a direct neurological influence.
- These results were consistent across both upper- and lower-limb reaction tests.
What this means in practice
Improved neural processing may translate into better movement accuracy, faster reflexes, and reduced fatigue during physical activity. For athletes, workers, and older adults alike, enhanced reaction time can support performance, coordination, and safety.
How we apply this clinically
- Assess reaction and coordination as part of our neurological screening process.
- Use precise spinal adjustments to restore joint motion and normal sensory feedback.
- Re-test reflex and coordination markers over time to track neurological improvement.
