Study Summary
The purpose of this study is to better understand how the peripheral and central nervous system interact to produce the sensation of pain and motor patterns in patients with achilles tendinopathy (AT). These findings will motivate the development of future clinical studies that incorporate knowledge about pain processing and movement strategies in patients with tendinopathy. Participants with achilles tendinopathy will receive an anesthetic injection to the achilles tendon in order to examine how reduced pain, detected by the peripheral nervous system, alters task performance and perception of pain. We hypothesize that there are factors within the central nervous system that contribute to continued pain and disability in patients with chronic AT.
Primary Outcome
Pressure pain threshold (PPT) at heel on contralateral side. A pressure algometer (Somedic, Farsta, Sweden) was applied perpendicular to the skin at a rate of 50 kilopascal/s with a 1cm2 tip. The participants pressed a button when the sensation of pressure first became painful (1/10 on NPRS). The mean of 3 trials per area represented the PPT.
Interventions
- DRUG Ropivacaine injection
