Referred Pain Areas in Subjects With a Recovered Radius Fracture

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.

About this study

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.

Who can participate

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Subjects with a history of distal radius fracture without pain at the moment of the study.

Exclusion criteria

  • Subjects with symptoms (e.g pain), functional limitations, history of other fractures in the upper limb or any other pathology.

Treatment and study plan

Pressure algometry and mapping referred pain areas

Other

The described procedures are tested at baseline and 24 hours after exercise-induced muscle soreness conditions.

Other names: Delayed onset muscular soreness

Primary outcomes

  1. A change in the area of referred rain

    Time frame: 24 hours (two experimental sessions separated by 24h).

    This outcome measure corresponds to the difference or change in the size and distribution of the pressure-induced referred pain area, between the two experimental sessions.

Secondary outcomes

  1. A change in pressure-pain thresholds

    Time frame: 24 hours (two experimental sessions separated by 24h).

    This secondary outcome measure corresponds to the force required to produce a MINIMAL pain(1 out of 10 on a 0-10 visual analogue scale)
