The purpose of this study was to determine concurrent validity of the Zulu translations of the English Numerical Pain Rating Scale-101 and the Patient Specific Functional Scale. The Numerical Pain Rating Scale-101 and the Patient Specific Functional Scale (ENRS-101 and the EPSFS) were translated into Zulu (ZNRS-101 1.0 and ZPSFS1.0) and were tested for face validity by means of a focus group session.
