About this study

Official title: The Effect of End-range Mobilization on Time Curve of Pressure Pain Threshold in Knee Osteoarthritis

Pain in knee osteoarthritis (OA) represents increased pain intensity due to peripheral and central sensitivity. Pressure pain threshold (PPT) is a widely applied technique for measuring the magnitude of peripheral and central sensitivity in knee OA. Despite several manual therapy techniques has been proven to increase PPT in knee OA, the effect of end-range mobilization on the time curve of PPT has not been evaluated so far in knee OA. The aim of this study was to investigate the effect of end-range mobilization on the time curve of PPT and some function-related measures in knee OA.

Read the detailed description

Knee osteoarthritis (OA) is the most common form of arthritis leading to a major disability worldwide. Although many mechanisms may contribute to knee pain severity, the patient-reported hyperalgesia can be attributed to peripheral and central sensitivity in knee OA. Amongst quantitative sensory testing methods, pressure pain threshold (PPT) measurement is a simple and commonly applied method for measuring somatosensory function in musculoskeletal disorders, just as in knee OA. Many trials have presented lower PPT in knee OA compared to healthy controls underlining the presence of peripheral and central sensitivity.

The different joint-based mobilization techniques may not only alleviate pain, but also increase pain tolerance to the locally applied mechanical pressure. Positive results of these techniques on increase of PPT has been reported in knee OA; however, the time curve of PPT has not evaluated so far in knee OA. Therefore, the aim of this study was to investigate the effect of end-range mobilization on the time curve of PPT and some function-related measures in knee OA.
