An anterior cruciate ligament injury occurs when the anterior cruciate ligament (ACL) is either stretched, partially torn, or completely torn. Your hip, knees, and ankles should be at 90 degree angles. When the muscle is stretched, so is the muscle spindle. In this test, the hip is flexed to 90 and it is important to relax the knee completely. Static stretching (SS) is a slow-paced controlled physical activity which involves putting the body part in a comfortable position that elongates the muscle without causing pain with low force for a prolonged duration of time (usually 30 seconds). High reliability resulted from strict body stabilization methods, a well-defined end point of motion, and accurate instrument placement. A variety of orthopedic patients can benefit from both static and pre-contraction stretching.[21]. There are several reasons for this. It may be performed whilst also doing a glute bridge as shown in the video or whilst doing a sit up. Isometric Hip Adduction with bridge or sit up. 9 benefits of stretching: How to start, safety tips, and more. The more we stretch in a week, the better the outcomes where according to certain studies stretching for more than three weeks served in decreasing stiffness and increasing the range of motion (two to eight-minute stretches served in increasing range of motion while ten minute stretches served in reobtaining normal range of motion)[8]. What is the 90/90 Hamstring Test? Dynamic Stretching (DS) is a controlled movement, unlike Ballistic stretches that involve bouncing movement and increases the risk of injury[12], which involves the performance of a movement progressively increasing the range of motion through successive repetitive motions till the end of the range is achieved.
