Randomized Controlled TrialIncreased pain sensitivity but normal function of exercise induced analgesia in hip and knee osteoarthritis--treatment effects of neuromuscular exercise and total joint replacement.
To assess exercise induced analgesia (EIA) and pain sensitivity in hip and knee osteoarthritis (OA) and to study the effects of neuromuscular exercise and surgery on these parameters. ⋯ To our knowledge, this is the first study of EIA in OA patients. Despite increased pain sensitivity, OA patients had a normal function of EIA.

Multicenter Study Observational StudyThe relationship between quadriceps muscle weakness and worsening of knee pain in the MOST cohort: a 5-year longitudinal study.
To determine whether quadriceps weakness is associated with elevated risk of worsening knee pain over 5 years. ⋯ Quadriceps weakness was associated with an increased risk of worsening of knee pain over 5 years in women, but not in men.

Multicenter StudyAcute postoperative pain following hospital discharge after total knee arthroplasty.
The increasingly shorter hospitalization following total knee arthroplasty (TKA) requires patients to assume earlier responsibility to self-manage their pain. Poorly managed acute pain increases the risk of persistent pain, reduces quality of life and increases unnecessary healthcare utilization. This study aims to examine post-discharge pain intensity, pain management behaviors and potential barriers to optimal self-management of pain. ⋯ Effective pain relief after hospital discharge following TKA is a challenge. Many participants reported significant pain, sought further medical help for pain relief and had inadequate information at discharge to effectively self-manage their postoperative knee pain.

Clinical TrialNeuropathic pain symptoms on the modified painDETECT correlate with signs of central sensitization in knee osteoarthritis.
Clinical tools are needed to identify and target a neuropathic-like phenotype, which may be associated with central sensitization (CS), in osteoarthritis (OA). The modified painDETECT questionnaire (mPD-Q) has face and content validity for identifying neuropathic-like symptoms in knee OA. To further validate the mPD-Q, this study assessed the unknown relationship between mPD-Q scores and signs of CS on quantitative sensory testing (QST) in knee OA. ⋯ Among painful OA knees, higher mPD-Q scores were associated with greater odds of having signs of CS. Thus, the mPD-Q may aid the identification of CS in people with chronic knee OA.

Cross-sectional and longitudinal associations between radiographic features and measures of pain and physical function in hand osteoarthritis.
Previous longitudinal studies have shown no associations between increasing amount of radiographic hand osteoarthritis (OA) and levels of hand pain/disability. In this longitudinal study, we aimed to study whether radiographic hand OA was related to pain/disability in cross-sectional and longitudinal settings focusing on joint-specific analyses. ⋯ Radiographic hand OA is associated with tenderness in the same joint, and erosive development strongly predicts future joint tenderness independent of other radiographic features.
