NCT04207164

Brief Summary

The aim of this study is to translate into Norwegian and cross-culturally adapt the Foot Functional Index- revised, short form (FFI-RS) according to international guidelines. Furthermore, the reliability and the validity, responsiveness as well as floor and ceiling effect of the Norwegian version of the FFI-RS will be determined.

Outcome Measures

Primary Outcomes (1)

  • Foot Functional Index revised short version ( FFI-RS)

    FFI-RS is a foot specific pain and function score. We will evaluate the reliability of the FFI-RS by testing the internal consistency (Cronbach's Alpha). Furthermore test-retest will be done with a second FFI-RS recording after one week (weighted Kappa). We will evaluate construct validity with other instruments (RAND-12 and NRS). To test the responsiveness of FFI-RS, we will evaluate the change in FFI-RS from baseline to 3 months with Patient Global Impression of Change score.

    Baseline, 1 week, 3 months

Secondary Outcomes (3)

  • Numeric Rating Scale (NRS)

    Baseline

  • RAND-12

    Baseline

  • Patient Global Impression Of Change Scale (PGIC)

Sampling MethodProbability Sample
Study Population

Patients with foot pain attending the Department of Physical Medicine and Rehabilitation at Oslo University Hospital (OUS), Norway will be included. Some of the patients will have the diagnosis Plantar Fasciopathy (PF) and is a part of the ongoing RCT from the same department at OUS: "The effectiveness of radial extracorporeal shock wave therapy (rESWT), sham rESWT, standardised exercised exercise programme or usual care for patients with plantar fasciopathy." (NCT03472989)(2017/1325 Regional Comimittee for Medical and Health Research Ethics,Norway). Rest of the study population will be patients with othe foot complaints.

You may qualify if:

  • Patients with pain localized in the foot
  • Patients understanding oral and written Norwegian

You may not qualify if:

  • Patients without pain in the foot
  • Patients not understanding oral and written Norwegian
