The aim of this paper is to study the changes of knee movement during walking for
patella femoral pain using flexible electro-goniometry, This is very important for gait research
and stability of knee, the start and end of the gait cycle were deter
mined by foot sensors, A
program was designed for signal processing of the data by Mat lab, Testes were carried out at
Hamish hospital in Damascus, Subjects were divided into two groups: 46 normal subjects and
21 patients. Results showed that the lesion effect on knee movement which the values of knee
flexion are less than normal, In the stance phase it is noted that the knee cancels its first
flexion, and In swing phase it noted that the decrease in knee flexion. It was also noted that
these values were varied between the patient tested.
The aim of this paper is to study the relation between muscles electrical activity and knee movement during walking for patient with patellafemoral pain by measurement both of electromyography (EMG) and changing of knee angle by electro-goniometer. T
he start and end of the gait cycle were determined by foot sensors, A program was designed for signal processing of the data, Testes were carried out at Hamish hospital in Damascus.
Subjects were divided into two groups: 46 normal subjects and 21 patient. Final results also showed that hamstring group activity and galf group activity decreases during stance phase because knee cancel it first flexion with increase in quadriceps femoris activity to keep extension of knee.
In swing phase, it is noted that the decrease in knee flexion and it depends on the increase in quadriceps femoris activity in all the period of swing phase, but hamstring group activity increases to keep hip instability, that is, it responds to increase activity of
quadriceps femoris with less knee flexion. The activity of subject muscles in the period of gait cycle is less than normal muscles.
