Pain is your body's warning that something isn't working properly. Here's what actually happens when you get hurt: Your body doesn't completely heal injuries—it patches them with scar tissue, then creates workarounds to keep you moving pain-free. This masks the real problem. When you first get injured, your body is remarkably good at compensating. It alters your movement patterns and recruits different muscles to take over for the damaged ones. This keeps you pain-free initially, but the original problem remains—it's just hidden. The problem with compensation: Your body can only maintain these workarounds for so long. Eventually, it exhausts its ability to compensate. When these backup systems fail, chronic pain emerges—sometimes in a completely different location from the original injury.
Recovery time varies based on your unique situation. Some patients experience noticeable relief after their first visit, while others need more time to address the underlying issues slowing their healing and recovery. Factors that influence your healing timeline include: Cause, Severity and complexity, Duration, Health history, Your body's healing capacity, and Lifestyle factors. Typical Treatment Timelines: Recent acute pain (days to weeks): 3-6 sessions. Moderate problems (1-6 months): 8-12 sessions. Chronic conditions (6+ months): 15-25+ sessions.
Chiropractic is a type of healthcare focused on your spine and nervous system, which controls everything in your body. When spinal joints get stuck or misaligned, they interfere with nerve communication, causing pain and health problems. Chiropractors restore proper movement and alignment with a chiropractic adjustment—a precise, controlled hand (or instrument) movement applied to specific joints that have become restricted in their movement. This helps restore proper joint motion and position, enhancing your body's natural ability to heal itself, without drugs or surgery.
Doctors of Chiropractic (DC) earn their degrees after extensive education and training, which makes them experts in the diagnosis, treatment, and prevention of neuromusculoskeletal conditions. In Quebec, chiropractors complete a 5-year doctoral program (245 university credits) at an accredited institution, similar to medical doctors (who complete 225 university credits). The 4,969+ hours of coursework covers: Fundamental sciences, Clinical sciences, Chiropractic sciences, Complementary disciplines, Real patient experience from year one, and 18-month supervised clinical internship.
Chiropractic care is one of the safest healthcare treatments available, with serious complications occurring in fewer than 1 in 1,000,000 treatments. Among the 9,000+ licensed practitioners across Canada, all with doctoral-level training and strict regulatory oversight, an estimated 30 million chiropractic treatments are delivered each year to 4.7 million Canadians—with an exceptional safety record. The most common effects are mild and temporary: Slight soreness for 24-48 hours, Brief stiffness as your body adjusts to improved movement, Temporary tiredness as your nervous system recalibrates.
Chiropractic care is safe, effective and widely used in Canada. Each year, nearly 5 million Canadians (about 1 in 7) see a chiropractor with 90% patient satisfaction rate—adding up to over 30 million chiropractic sessions annually across the country. Chiropractic helps patients recover faster, avoid unnecessary medications or surgeries, and live pain-free—with millions of success stories every year.
Applied Kinesiology (AK) was developed by Dr. George Goodheart in 1964. It combines principles from chiropractic, osteopathy, physiotherapy, nutrition, and manual therapy to help practitioners address stubborn, complex conditions. By challenging your body and observing its real-time feedback through manual muscle testing and pain point responses, practitioners decode your body's signals to identify hidden stressors in three key areas: Mechanical, Chemical, and Emotional. Once the source is identified, precise, body-specific corrections are applied. Progress is then tracked during each session through manual muscle testing and pain point responses—ensuring treatment efficiency.
