The initial effects of knee joint mobilization on osteoarthritic hyperalgesia

Penny Moss, Kathleen Sluka and Anthony Wright

Physiotherapists often employ lower limb joint mobilization to reduce pain and increase function. The purpose of this study was to investigate the initial effects of accessory knee joint mobilization on measures of pain and function in individuals with knee osteoarthritis. Thirty-eight subjects with mild to moderate knee pain participated. The effects of a 9-min, non-noxious, AP mobilization of the tibio-femoral joint were compared with manual contact and no-contact interventions. Results demonstrated a significantly greater increase in pressure pain threshold (PPT) following knee joint mobilization than after manual contact or no-contactinterventions.  The authors concludet hat this study therefore provides new experimental evidence that accessory mobilization of an osteoarthritic knee joint immediately produces both local and widespread hypoalgesic effects. It may therefore be an effective means of reducing pain in this population.
