The Middle Cross Syndrome and ARPwave Therapy

Global Approach to addressing biomechanical deficits

Motus Methods employs targeted ARPwave protocols to rectify these middle cross dysfunctional patterns, adopting a holistic approach aimed at addressing comprehensive biomechanical deficiencies throughout the body. Through this systemic methodology, it is possible to enhance structural integrity and functional performance.

Middle Cross Syndrome, or Layer Syndrome, manifests as a postural imbalance that incorporates aspects of both Upper Crossed Syndrome (UCS) and Lower Crossed Syndrome (LCS). This condition results from muscle imbalances across the upper and lower body, presenting a distinct postural alignment characterized by pronounced spinal curves. The interplay between anterior and posterior fascial slings contributes to specific postural deficiencies, impacting the biomechanics of both upper and lower extremities and increasing the risk of injury.

Clinical observations frequently indicate that dysfunctional slings are prevalent between the dominant leg and the non-dominant arm. For instance, in a left-footed individual, the compromised sling extends from the left hip to the right shoulder, leading to abnormal biomechanics in the left lower extremity characterized by internal rotation of the femur, excessive valgus at the knee, and overpronation of the foot. Correspondingly, a similar biomechanical pattern is observed in the right upper extremity, manifesting as internal rotation of the humerus and pronation of the hand and wrist.

These abnormal biomechanical configurations predispose individuals to prevalent overuse injuries. For example, excessive valgus at the knee (genu valgus) can result in lateral tracking of the patella, leading to inflammation and pain in the patellofemoral joint. A symptomatic approach may focus on addressing the inflammation at the patellofemoral joint utilizing various therapeutic techniques; however, such interventions do not rectify the root cause of the dysfunction, specifically the internal rotation of the lower extremity attributable to middle cross syndrome.

At Motus Methods, we have developed protocols utilizing ARPwave technology to address and correct the biomechanical dysfunction associated with middle cross syndrome. This comprehensive approach empowers practitioners to achieve sustainable outcomes by targeting the underlying causes of common overuse injuries, including patellar tracking issues, plantar fasciitis, and hip pain in the lower extremity, as well as shoulder impingement, tennis elbow, and carpal tunnel syndrome in the upper extremity.
