Time Difference Between Onsets of Lateral And Medial Hamstring Muscles During Gait in Patients With Patellofemoral Pain.

No results posted yet for this study

Summary

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.

Conditions

  • Patellofemoral Pain

Interventions

OTHER

kujala patellofemoral pain scale

Kujala patellofemoral pain scale was used to evaluate knee functions of the PFP subjects.

DIAGNOSTIC_TEST

Surface EMG

The surface EMG electrodes (silver/silver chloride, pre-gelled, Ambu Blue Sensor, Denmark) (Konrad P.) with an interelectrode distance of 20 mm between centers were used to record an EMG signal during walking. Portable 8 channel (TELEEMG, BTS, Milan, Italy) with built in x10 amplifications, 10-450 Hz bandpass and sampling rate of 1000 Hz were used for recording. The location and orientation of the electrodes for each MH (ST) and LH (BF) were identified according to SENIAM (Surface ElectromyoGraphy for the Non-Invasive Assessment of Muscles) criteria.

OTHER

Q angle measurement

Q angle measurement was applied to both patellofemoral pain and control group subjects in standing position.
