Patellofemoral Pain Clinical Trial
Official title:
Is There a Time Difference Between Onsets of Lateral and Medial Hamstring Muscles During Gait in Patients With Patellofemoral Pain Comparing to Healthy Subjects?
Early activation of lateral hamstrings (LH) in respect of medial hamstrings (MH) may cause abnormal knee abduction and external rotation moments in individuals. This situation may increase the risk of ligament injury and may be the reason for susceptibility of patellofemoral pain (PFP). The aim of this study is to compare the time delays in electromyographic studies between medial and lateral hamstrings in patients with PFP and asymptomatic subjects.
Patellofemoral pain (PFP) is a very common complaint in younger population with still unclear
and controversial etiology. It was suggested that a combination of intrinsic and extrinsic
factors cause PFP. The strain of the retropatellar subcondral bone caused by excessive
lateral patellar tracking is known to be the one among intrinsic factors (Thomee R.1999).
Imbalance of the dynamics between knee extensor muscles, Vastus Medialis (VM) and Vastus
Lateralis (VL), has also received a great research interest during last 10 years. However,
uneven timing between onsets of counterpart knee flexor muscles, Lateral and Medial
hamstring, were just considered as a possible etiological factor of the PFP (Patil S.2011),
yet this hypothesis remains to be proven. The investigators aimed to investigate whether
there is a relative time delays of the LH (biceps femoris, BF) and MH (semitendinosus, ST)
during the walking at the self-selected speed in patients with patellofemoral pain. Even
though dynamic EMG investigations are challenging because of cross-talks between muscles,
hence difficult to determine clearly onset times, the investigators think that any
information acquired during walking would be highly important because patellofemoral pain is
mainly exaggerated by dynamic activities.
15 patients who were diagnosed with PFP (age 28.73±7.44, height 169.73±7.09, weight
67.47±14.31) and 15 asymptomatic subjects (age 30.47±6.22, height 167.87±7.81, weight
67.87±13.48) were recruited in the study. The inclusion criteria for PFP subjects was
presence of the anterior and retropatellar pain for minimum 2 months scaled as 3 in
accordance with Numeric Analog Scale during at least two of the following activities: stair
descending, ascending, squatting, prolonged sitting, jumping, sitting on the knees. Surface
EMG was recorded from Medial Hamstring and Lateral Hamstring muscles at 1000 Hz sampling rate
during walking at participants' normal walking speed. EMG data obtained from 5 gait trials
were evaluated. The EMG traces were full wave rectified and low pass filtered at 50 Hz. Delay
in timing before heel strikes between MH and LH was calculated. Statistical significance
between differences in time delays was analysed using "paired sample t-test".
