Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the present study is to investigate pressure algometry and pressure-induced referred pain areas in pain free individuals with a history of distal radius fracture (fully recovered) compared with age and gender matched healthy controls without history of fracture. It is hypothesized that individuals with a recovered radius fracture will have a facilitated referred pain patter towards the wrist but normal pressure pain sensitivity.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Musculoskeletal injuries, nociception and pain can increase the sensitivity of the central pain mechanisms, which can be extended even after tissue recovery. However, little is known about the status of these central pain mechanisms once subjects are fully recovered from the tissue injury and pain. This information would help to explain pain conditions in which recurrence of the pain episodes is common (e.g low back pain or shoulder pain).

Pressure-pain thresholds have been widely used in pain research to test the sensitivity of the pain system. Additionally, referred pain has been shown as a valid biomarker for the sensitization of the pain system.

The aim of the present study is to investigate pressure pain sensitivity and referred pain patterns of individuals with a history of recovered fracture, compared with healthy controls.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Recovered fracture group

The interventions will be conducted on both groups, on two experimental (approximately 45 minutes per session) sessions separated by 24 hours.Pressure algometry consists of measuring pressure pain thresholds at three bilateral muscle sites.Mapping referred pain areas consists of recording on an electronic body chart the area of pain induced by 60s pressure stimulation at 1.2 times the force needed to reach the pressure pain threshold, exerted on the extensor carpi radialis and the infraspinatus muscles.As group-differences can be attenuated at baseline but emerge on a sensitized (exercise-induced soreness) state, these procedures are performed at baseline and 24 hours after evoking exercise-induced muscle soreness.
