Four muscles make up the quadriceps: the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps is involved in moving the hip and knee and supporting body weight. The rectus femoris is more susceptible to strain injury than the other three muscles. The injury can result from repetitive contraction without adequate relaxation or forceful contraction, which may occur in sprinting, jumping, football, hockey, and weight training.
Dry needling acupuncture is an effective treatment for this injury. Needles can be applied directly into the inflamed, tender, swollen, and painful area and also into related muscles on the hip, thigh, and lower leg. In addition, the treatment is used to balance the entire musculoskeletal system. Two treatment sessions per week should be provided.
