To investigate the effects of spinal manipulation for Achilles tendinopathy; a pilot study

This pilot study is testing whether adding spinal manipulation (an adjustment technique used by physiotherapists and chiropractors) to a standard exercise program improves recovery from Achilles tendinopathy — a painful condition affecting the thick tendon at the back of the ankle. Participants will all do a 4-week program of eccentric (lengthening) exercises, and half will also receive spinal manipulation. Researchers will measure how well the ankle functions after treatment. You may be eligible if: - You are between 18 and 65 years old - You have been diagnosed with chronic Achilles tendinopathy by an advanced physiotherapist - You are available twice a week for a 20-minute physiotherapy appointment over 4 consecutive weeks You may NOT be eligible if: - You have a contraindication to spinal manipulation (e.g., osteoporosis, rheumatoid arthritis, cancer) - You have tendinopathy in both ankles - You have Scheuermann's disease - You have a neurological disease - You are pregnant - You are unable to understand the treatment or study requirements Talk to your doctor about whether this trial might be right for you.
