Filter by:Patellofemoral pain syndrome (PFS) is a musculoskeletal problem characterized by pain felt in the front of the knee or behind the patella, commonly affecting individuals in adolescence or young adulthood, especially those engaged in sports such as cycling and running. It is one of the most encountered knee injuries and can have a poor prognosis. The intensity of knee pain increases during functional activities such as stair climbing, squatting, running, and jumping due to the increased patellofemoral joint reaction force. A disturbance in postural stability is observed in individuals with PFS due to pain during functional activities. Studies examining changes in foot posture, plantar pressure, and postural balance in individuals with PFS are quite limited and controversial. Moreover, research that simultaneously investigates these parameters and interprets the results is scarce. Some studies have utilized detailed technical systems such as medical imaging or motion analysis, while practical methods incorporating foot posture and plantar pressure analyses are available and easy to use in clinical settings. There is a lack of literature on the easy assessment and interpretation of plantar pressure, postural balance, and functional activities in individuals with PFS. Within the scope of this project, the plan is to assess plantar pressure, postural balance, and functional activities in individuals with PFS. The aim is to quickly interpret the biomechanical changes occurring in these individuals and guide rehabilitation programs based on the obtained data. The use of practical and fast assessment methods in planning treatments for PFS is crucial for early rehabilitation planning. Practical methods such as foot posture, plantar pressure, and postural balance assessments, which can be used in clinical settings, may provide benefits in shaping rehabilitation goals related to lower extremity alignment in individuals with PFS. The objective of this study is to compare the foot posture, plantar pressure, and postural stability of individuals with PFS with healthy individuals. Additionally, the investigators aim to investigate the relationship between foot posture, plantar pressure parameters, postural balance, and functional level in individuals with PFS. Through these objectives, it will be possible to identify potential parameters that could be effective in rehabilitation processes and contribute to determining treatment programs by revealing biomechanical changes in individuals with PFS.
Patellofemoral pain is a common complaint especially in young adults. It can be caused by patellar maltracking. Part of this is a patella alta. When patellar maltracking is the cause of the problem and conservative therapy fails, surgery, a tibial tuberosity transposition, may be considered. Most research has been done in patients with recurrent patella luxation. However, in patients without luxation, research is scarce. It is known that patients with patella alta have an increased risk of developing patellofemoral chondropathy due to increased pressure. With this study, we aim to investigate whether and how a tibial tuberosity transposition in patients with patella alta and no instability affects the degree of patellofemoral chondropathy and patient satisfaction after 10 years. This will allow us to educate patients regarding long-term outcomes better.
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.
The purpose of this study is analyze the immediate effect of selective neuromuscular electrical stimulation of vastus medialis obliquus (VMO) in the electrical activity of VMO and vastus lateralis (VL) and in the isokinetic performance of women with patellofemoral pain syndrome.
