We have been investigating positional problems and symptoms that TOS patients complain of when going to bed, and herein report the results of 1201 cases treated with the TOS-pillow over the past 8 years. Problems related to sleep included patients inability to sleep on their back at night, therefore they slept in the lateral position; they usually did not use their pillows and would often have neck pain, stiffness and numbness when they got up in the morning. The TOS-pillow consists of a head and neck portion designed originally according to the patient’s posture and bilateral shoulder parts. At our outpatient department, patients were instructed according to our pillow guidance, and they purchased the pillow after a 2-week trial. The TOS-pillow fits the shape of patient’s head, neck, and shoulder, enlarges their costoclavicular space, relaxes the surrounding muscles, and allows satisfactory sleep. TOS-pillow treatment has been well received by many patients in the long-term follow-up.
