Asymmetries and relationships between dynamic loading, muscle strength, and proprioceptive acuity at the knees in symptomatic unilateral hip osteoarthritis.

Introduction: High joint loading, knee muscle weakness, and poor proprioceptive acuity are important factors that have been linked to knee osteoarthritis (OA). We previously reported that those with unilateral hip OA and bilateral asymptomatic knees are more predisposed to develop progressive OA in the contralateral knee relative to the ipsilateral knee. In the present study, we evaluate asymmetries in muscle strength and proprioception between the limbs and also evaluate relationships between these factors and joint loading that may be associated with the asymmetric evolution of OA in this group.

Turkish lupusPRO: cross-cultural validation study for lupus.

LupusPRO is a disease-targeted patient-reported outcome measure that was developed and validated from and among US patients with systemic lupus erythematosus (SLE). We herein report the results of the cross-cultural adaptation and validation study of the Turkish translated version of the LupusPRO. Turkish LupusPRO and the Medical Outcomes Study Short Form (SF-36) (Turkish) were administered to the Turkish lupus patients.

Cross-cultural validation of a disease-specific patient-reported outcome measure for systemic lupus erythematosus in Canada.

Objective: The LupusPRO, a disease-targeted patient-reported outcome measure, was developed and validated in US patients with systemic lupus erythematosus (SLE). We report the results of the cross-cultural validation study of the English version of the LupusPRO among patients in Canada with SLE.

Method: The LupusPRO was administered to English-speaking Canadian patients with SLE.
