Possible involvement of the autonomic nervous system in cervical muscles of patients with myalgic encephalomyelitis / chronic fatigue syndrome (ME/CFS).

Background: Patients with myalgic encephalomyelitis / chronic fatigue syndrome (ME/CFS) sometimes present with stiffness of the cervical muscles. To investigate the pathophysiology of ME/CFS, this observational study compared patients with versus without recovery from ME/CFS through local modulation of the cervical muscles.

Methods: Over a period of 11 years, a total of 1226 inpatients with ME/CFS who did not respond to outpatient care were enrolled in this study.

Mechanical Behavior of GFRP Connection Using FRTP Rivets.

In recent years, the application of fiber-reinforced plastics (FRPs) as structural members has been promoted. Metallic bolts and rivets are often used for the connection of FRP structures, but there are some problems caused by corrosion and stress concentration at the bearing position. Fiber-reinforced thermoplastics (FRTPs) have attracted attention in composite material fields because they can be remolded by heating and manufactured with excellent speed compared with thermosetting plastics.

Cervical muscle diseases are associated with indefinite and various symptoms in the whole body.

Purpose: Patients with various and indefinite symptoms in the whole body occasionally have coincident with stiffness or tenderness of the cervical muscles. This prospective case series examined the effect of local modulation of the cervical muscles in patients with cervical disorders reporting indefinite whole-body symptoms.

Methods: A total of 1863 hospitalized patients with cervical disorders accompanying three or more indefinite whole-body symptoms, who were resistant to outpatient care, were enrolled in this study for 12 years.

Effect of intensive inpatient physical therapy on whole-body indefinite symptoms in patients with whiplash-associated disorders.

Background: A considerable number of patients with whiplash-associated disorders (WAD) report variable and indefinite symptoms involving the whole body, despite there being no evidence of direct injuries to organs other than the neck. However, little is known about their management or underlying mechanism. This study examined the effect of intensive physical therapy at the cervical muscles in patients with WAD reporting whole-body indefinite symptoms.

Cervical neuro-muscular syndrome: discovery of a new disease group caused by abnormalities in the cervical muscles.

Our previous study of whiplash injury found that abnormalities in the cervical muscles cause autonomic dystonia. Further research has found that abnormalities in the cervical muscles cause headache, chronic fatigue syndrome, vertigo, and dizziness. We named this group of diseases cervical neuro-muscular syndrome.
