2. exercise example
Starting position same as 1. without weight load Exercise execution same controlled tensing of the VMO without lifting the heel Important: the tensing should be performed under eye control and palpation control. Starting position Standing, stepping position, the affected leg is in front and slightly bent Exercise execution the heel is pushed forward, pushed inwards into the floor and held. Starting position Stand on the affected leg Exercise execution the hands are folded and the arms are moved towards the ceiling, the eyes follow
Exercise example 5
Starting position: Stand on the affected leg Exercise execution: Hands are folded and arms moved from right to left, eyes follow Increase: Use unstable surface (therapy devices such as air pad or wobble cushion, at home a foam cushion is sufficient) The balance training in the one-legged stand can be well integrated into everyday life! (brushing teeth, telephoning, peeling potatoes). Caution: One-legged stands should not be done on one leg for more than half a minute!
Anterior knee pain due to muscle weakness of the global thigh muscles
Global muscle system at the knee joint
The global muscular system of the knee joint includes the quadriceps (quadriceps) and the ischiocrural muscles (thigh flexors). Their function is to carry out the stretching and bending movement of the knee joint during the knee extension and to stabilize the knee joint in the various bending phases.
- Go
- Running
- Sit down and
- Get up
- Stairs down – and up
Physiotherapeutic examination muscle weakness thigh extensor
The physiotherapist examines the patella position and run (position of the patella and its movement during the tension of the thigh extensor) at rest and under tension of the M. Quadriceps. In addition, the strength and functionality of the thigh extensors and thigh flexors are examined, since muscular balance (muscle balance) is crucial for stabilizing the knee joint.Muscular imbalance (muscle imbalance) -left- caused by quadricep weakness results in knee joint instability, which in turn can promote premature cartilage damage. The physiotherapist allows the patient to perform light knee bends on the affected leg, paying attention to the execution and maintenance of the leg axis (e.g. the deviation of the knee joint to the x-axis).
She/he then tests the exercise on the healthy leg. The so-called eccentric (slowing down muscle power, e.g. when going down stairs) quadriceps work is tested by comparing the sides. If pain occurs during the test, the position of the trunk or the leg axis is changed when bending the knee. If a change in symptoms (e.g. pain reduction) occurs as a result, the examiner can draw conclusions about a guiding instability of the kneecap and modify the strengthening exercises.
