Effects of device-performed and manual hip traction and vibration therapy in older adults with symptomatic hip osteoarthritis: A randomized single-blind controlled trial.

BACKGROUND: Traction-and-vibration-therapy (TVT) relieves pain in participants with hip osteoarthritis. Hip TVT is usually performed manually by the physiotherapist. OBJECTIVE: A medical device was developed to perform hip-TVT in order to investigate effects on hip disability, pain intensity, recovery of balance and functional mobility in older adults with hip osteoarthritis and also to reduce physiotherapists' workload and help standardize treatment of hip TVT. METHODS: In a block-randomized 3-month controlled trial involving 28 older adult participants with symptomatic primary hip osteoarthritis (SPHOA), one group (n= 10) received device-performed TVT, one (n= 10) manual TVT, and one (n= 8) sham/placebo therapy. Hip disability (Harris Hip Score), pain intensity (visual-analog-scale), recovery of balance and gait (Functional Gait Assessment) and functional mobility (Timed-Up-and-Go-test) were assessed at baseline, after 3 weeks without intervention, and after 3-month intervention. RESULTS: The Device TVT and Manual TVT groups exhibited superior outcomes compared to the Placebo group in terms of hip disability (p= 0.005 and p< 0.001, respectively), pain intensity (p= 0.002 and p< 0.001, respectively), and functional mobility (TUG) (p= 0.012 and p= 0.011, respectively). Furthermore, the recovery of balance and gait (FGA) showed a significant improvement in the Device TVT group when compared to the Placebo group (p= 0.043). The effect sizes ranged from 0.17 to 0.51, indicating moderate to large effects. CONCLUSION: Device-performed-TVT is comparable to manual hip-TVT for reducing pain and improving mobility in older adults with SPHOA, and may be beneficial in terms of reducing physiotherapists' workload and better therapy standardization.

Translation, cross-cultural adaptation and validation of the Slovenian version of Harris Hip Score.

INTRODUCTION: The Harris Hip Score is the most widely used outcome measure for the assessment of hip pathologies. An official Slovenian version has not been culturally adapted and validated. The aim of this study was to create a Slovenian valid and reliable version of the HHS. MATERIALS AND METHOD: The HHS was translated and modified in Slovenian. The measurement properties of the Slovenian HHS were tested in 42 patients suffering from different hip pathologies. Reliability, responsiveness, construct validity, convergent/divergent validity and content validity of the Slovenian version of the HHS were tested. RESULTS: Only minor adaptation was required in the translation process. The internal consistency of the HHS expressed by Cronbach's alpha was 0.94. The test-retest reliability expressed by the intraclass correlation coefficient was 0.983. The correlations of the HHS scale with the WOMAC scale (r = - 0.877) and the VAS scale (r = - 0.717) were statistically significant. The highest correlation between the HHS and SF-36 was with the General Health dimension (r = 0.61). while the lowest correlation was with the SF-36 Mental Health dimension (r = 0.43). MDC95% was 10.1. No floor or ceiling effects were found. CONCLUSION: Slovenian version of HHS seems to has an acceptable level of reliability and validity. Slovenian HHS is short, comprehensible and easy to administer and interpret. TRIAL REGISTRATION: Approved by the Slovenian National Medical Ethics Committee (0120-46/2019/19).
