Janda’s Layer syndrome (also referred to as “Stratification Syndrome”) is a combination of both upper and lower crossed syndromes (Figure 4-7). There is marked impairment of motor regulation that has increased over a period of time. Patients with layer syndrome have a poorer prognosis than those with isolated UCS or LCS due to the long-standing dysfunction. This pattern is often seen in older adults and in patients suffering unsuccessful surgery for herniated nucleus pulposus (HNP).
