Abstract

Background. Knee joint ostcoarthritis is painful and with an overweight of female incidence. The cardinal symptom is pain, which Causes compensatory gait changes, and gender differences in pain sensitivity exist. Impact loadings at heel strike during walking are suspected as a co-factor in development of knee osteoarthritis. Thus the purpose of this study was to investigate the influence of experimental muscle pain and gender oil generation and attenuation of impact loading during walking. Methods. Ten healthy males and 10 healthy females were recruited. Impact loadings during walking were measured using force platforms and accelerometers attached to the tibia and sacrum. Impact ground reaction force peaks and loading rates, and peak accelerations were used to quantify impact loadings. Attenuation was quantified by means of a transfer function between the tibial and sacral accelerometer signals, and the relative peak acceleration reduction. Knee joint kinematics were collected using a three-dimensional movement analysis system. The study was a cross-over study and data were collected before, during, and after experimental vastus medialis pain and a control situation. Findings. Experimental muscle pain did not affect generation or atternuation of impact loading in either gender. While the impact loading magnitude was similar across genders, lower loading rates and more efficient attenuation were observed in females. Interpretation. It is concluded that generation and attenuation of impact loadings during walking are independent of quadriceps pain in both genders. The present study does not provide any evidence of the tested variables to address the gender differences in loading rates and attenuation. (C) 2007 Elsevier Ltd. All rights reserved
