The level of evidence for PMPs varied across different test procedures in different types of PJP .
H and -held pressure algometry is the only test procedure that showed moderate positive evidence of intrarater reliability , agreement , and responsiveness , simultaneously , when it was investigated in patients with chronic knee osteoarthritis .
BACKGROUND Test procedures that were developed to assess somatosensory abnormalities should possess optimal psychometric properties ( PMPs ) to be used in clinical practice .
The aim of this systematic review was to evaluate the literature to assess the level of evidence for PMPs of test procedures investigated in individuals with peripheral joint pain ( PJP ) .
Prediction of postoperative pain by preoperative pain response to heat stimulation in total knee arthroplasty
Summary Pain responses to 2 types of preoperative heat stimuli were not independent clinical ly relevant predictors for postoperative pain after total knee arthroplasty . ABSTRACT It has been estimated that up to 54 % of the variance in postoperative pain experience may be predicted with preoperative pain responses to experimental stimuli , with suprathreshold heat pain as the most consistent test modality . This study aim ed to explore whether 2 heat test paradigms could predict postoperative pain  after total knee arthroplasty ( TKA ) . Patients scheduled for elective , unilateral , primary TKA under spinal anesthesia were consecutively included in this prospect i ve , observational study . Perioperative analgesia was st and ardized for all patients . Outcomes were postoperative pain during walk : from 6 to 24 hours ( primary ) , from postoperative day ( POD ) 1 to 7 ( secondary ) , and from POD 14 to 30 ( tertiary ) . Two preoperative tonic heat stimuli with 47 ° C were used ; short ( 5 seconds ) and long ( 7 minutes ) stimulation upon which patients rated their pain response on an electronic visual analog scale . Multivariate stepwise linear and logistic regressions analyses were carried out , including 8 potential preoperative explanatory variables ( among these anxiety , depression , preoperative pain , and pain catastrophizing ) to assess pain response to preoperative heat pain stimulation as an independent predictor for postoperative pain . A total of 100 patients were included , and 3 were later excluded . A weak correlation [ rho ( 95 % confidence interval ) ; P value ] was observed between pain from POD 1 to 7 and pain response to short [ rho = 0.25(0.04 to 0.44 ) ; P = .02 ] and to long [ rho = 0.27 ( 0.07 to 0.46 ) ; P = .01 ] heat pain stimulation . However , these positive correlations were not supported by the linear and logistic regression analyses , in which only anxiety , preoperative pain , and pain catastrophizing were significant explanatory variables ( but with low R‐squares ; 0.05 to 0.08 ) . Pain responses to 2 types of preoperative heat stimuli were not independent clinical ly relevant predictors for postoperative pain after TKA
