Description

Forward head posture (FHP) is a common postural disorder (66%), occurring when the head is anterior to a vertical line passing through the center of gravity. This malalignment causes muscle weakness in deep cervical flexors and shortened opposing cervical extensor muscles. This posture increases lordosis in the lower cervical spine, leading to increased extension over upper, and flexion over the lower cervical spine. Abnormal postures can lead to headaches, myofascial pain syndrome, abnormal scapular movement, temporomandibular disorders, and limited cervical range of motion.

Muscles of the neck, back and lower limb are interconnected through myofascial called superficial backline. Prolonged forward head posture affects muscles and involved in superficial backline. So remote muscle stretching has a same effect on local neck muscles.

Muscle energy technique is a soft tissue technique designed to improve musculoskeletal function through stretching tight muscles and fascia, to reduce pain and improve circulation. MET is characterized by a patient-induced skeletal muscle contraction against physiotherapist resistance in a controlled direction and position. Pathological barrier of a muscle is located through joint positioning which is followed by active muscle contraction by the patient moving away from the resistance followed by relaxation of the muscle. A new pathological barrier is located through passive movement and process is repeated. The rationale for the use of these techniques is to identify the effects of MET of lower limb superficial backline muscles which are interconnected with cervical muscles through myofacial chain, on cervical pain ROM, craniovertebral angle , disability and cervical proprioception.
