Lower Hamstrings – Strain or Tear Treat This Condition with Active Isolated Stretching

Lower hamstring problems may be caused by inadequate hamstring flexibility, weakness of the gluteus maximus and adductor magnus are important hip extensors, which if weak, allow increased load on the hamstrings.  Hamstring weakness in which the short head and long head of the biceps femoris may not have optimum function together or from weakness during eccentric (lengthening) contraction of the hamstring muscles.  The hamstring strain may be at the distal semitendinosus, semimembranosus, or double insertion biceps femoris.Benefits of AIS on Condition:

Benefits of Using AIS

Stretch the specific lower and upper hamstring muscles, hip adductors, hip abductors, quadriceps and calf muscles. Strengthen the hamstrings, performing specific leg curls in the neutral position, then having the tibia rotated inward, followed by the tibia rotated outward. Perform hip hyperextension in all three straight leg positions including the femur in the neutral position, the femur rotated inward and the femur rotated outward.
