Abstract

Functional problems such as walking are the most common problems in patients with knee OA because this is due to changes in the activity patterns of the quadriceps and hamstrings muscle groups. Objective: to see the activation and co- activation of the muscle groups of quadriceps and hamstrings when walking. This type of research is a cross sectional method, which is emphasizing the time of measurement or observation of data at one time and one time on free and bound variables. The number of respondents is three women. Two respondents had a temporary clinical diagnosis of knee OA, one was a woman who worked in the office for 8 h a day. Using electromyographic placed on the rectus femrois and biceps femoris muscle. Seen while walking on a treadmill. Results In this study there was a co-activation of the hamstrings muscle group especially in the biceps femoris muscle against the quadriceps muscle group especially in the rectus femroris muscle during the early swing phase in all respondents. The largest quadriceps and hamstrings muscle group co-activation ratio occurred in respondents with clinical diagnosis of knee OA with low level activity then respondents with clinical diagnosis of knee high level activity OA and in respondents without clinical complaint of knee OA diagnosis in Surakarta, Central Java.
