Central Neuromuscular Dysfunction in Patellofemoral Pain

Sponsor: Hacettepe University

Summary

Patellofemoral joint problems constitute a significant portion of knee pain and injuries. Patellofemoral pain, which is among these problems, is a common musculoskeletal disorder with a poor long-term prognosis in the community. Disturbances in M. quadriceps femoris muscle function have been observed in individuals with patellofemoral pain. M. Quadriceps femoris dysfunction includes arthrogenic muscle inhibition (AKI). Abnormal joint afferent discharge, which is the cause of AMI, affects the excitability of the spinal and supraspinal tracts by limiting muscle activation and can have strong effects on the central nervous system. Therefore, not only spinal reflex pathways but also corticomotor and intracortical pathways are involved in the neurophysiological mechanism of AKI. Transcranial magnetic stimulation (TMS) of the motor cortex is used to evaluate the integrity of the motor pathways and to obtain information about the connections of the relevant brain regions. The limited number of studies examining the changes in corticomotor excitability of M. Quadriceps femoris with TMS in individuals with patellofemoral pain, and the differences in results, and changes in corticomotor excitability at different angular values of the knee joint during active movement have not been examined in studies to date, so it will be applied to individuals with patellofemoral pain by knowing more about central neuromuscular involvement. The aim of this study is to compare central neuromuscular involvement in individuals with patellofemoral pain with healthy individuals, and to compare the isometric muscle strength of the M. Quadriceps femoris muscle, force sense, knee joint function, quality of life, physical activity and kinesiophobia levels by comparing them with healthy individuals of the same age and gender. In the study, corticomotor involvement of M.Quadriceps femoris with TMS, isometric muscle strength with Lafayette Manual Muscle Tester, force sense with pressurized biofeedback unit, knee joint function with Kujala Patellofemoral Scale, quality of life with Short Form-36, physical activity with International Physical Activity Questionnaire, kinesiophobia l will be assessed with the Brief Fear of Movement Scale.
