Patellar taping is one of the method of treatment of patellofemoral pain but effect of patellar taping on VMO and VL reflex as a one of mechanism of pain relieve is questionable. The purpose of this study were to investigate the effect of patellar taping on the timing of the onset of VMO and VL reflex in patients with patellofemoral pain and to compare the obtained of VMO and VL reflex with normal subject. Onset time of VMO & VL reflex to a special mechanical stimulus (tapping the quadriceps tendon) were measured in 21 healthy subjects and 15 patients suffering from patellofemoral(20-30 years old). Each subject’s quadriceps tendon was tap armed reflex hammer and EMG signals were recorded. Following this recording, the patellar taping was performed on the patients using leucoplast tapes,so that their pain score dropped to less than 50% of their original pain according to VAS, when one leg provocation maneuver was used to provoke the pain in the patellofemoral joints. Latency of the onset of the reflex response of VMO and VL were different in normal subject’s compare to the patients. Taping of patellofemoral joint, as performed in this study, change the timing of the activity of the VMO in the patients suffering from patellofemoral pain. Reduced latency of VMO activation as the result of taping as observed in this study, may have a positive effect on the patellar tracking. Further studies are recommended in order to substantiate the clinical effects of such that change caused by patellar taping.

This research was conducted to examine the effect of adding forward and backward running in a wobble training program on some of functional static balance tests. In this research 30 young male(15-35 years) with sprain of lateral ligaments (grade I,II) of ankle joint were selected by non-probability sampling and assigned randomly into three groups: Group 1 included 10 subjects that performed 15 minutes forward running training and then 15 minutes wobble board training. Group 2 included 10 subject that performed 15 minutes backward running training and then 15 minutes wobble board training. Group 3 included 10 subjects that performed just 15 minutes wobble board training. The functional static balance tests included the most possible time of standing on the injured leg in the straight posture on the surface by eye open(A), and eyes closed (B) and non-injured leg in the straight posture on surface by eyes open and eyes closed. The testing period lasted 6 weeks with 3 sessions per week. Measurments were taken at the beginning and every two weeks hence forward at 4 stages. At the end of 6 th week, the difference between 3 groups (A) statistically was not significant but there was significant difference of mean data between 2 and 4 weekstraining in 3 group (B). That is, backward running for 4 weeks has a good effect on the static balance by wobble board training.
