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.
