Valgusfaase

Valgusfaase refers to a specific phase in the gait cycle, particularly during walking or running. It is the period after the foot has made contact with the ground and before it begins to lift off again. This phase encompasses several key biomechanical events. It begins with heel strike and continues through the stance phase where the foot bears the body's weight. During valgusfaase, the ankle joint typically undergoes pronation, a rolling inward motion. This pronation is a natural shock absorption mechanism, allowing the foot to adapt to uneven surfaces. The arch of the foot flattens as weight is transferred from the heel to the forefoot. The knee joint may also exhibit some degree of valgus, meaning it moves inwards. Following the peak of weight bearing, the foot begins to supinate, rolling outwards, in preparation for the swing phase when the foot leaves the ground. Variations in the degree and duration of pronation and knee valgus during this phase can be influenced by factors such as foot structure, muscle strength, and the type of activity. Understanding valgusfaase is important in analyzing biomechanical efficiency and identifying potential causes of musculoskeletal issues in the lower limbs.
