The effects exerted on the cervical spine by a traction of 150 N was studied by means of an improved radiographic technique. The technique is presented together with results from a study including fifteen test subjects with and without clinical symptoms of neck pain. In a minority of discs a widening not exceeding 1 mm was seen. This widening was not correlated to presence of roentgen signs indicating degenerative disease of the disc nor to clinical symptomatology.
采用改良的放射成像技术研究了150牛牵引力对颈椎的影响。该技术与一项研究结果一同呈现，该研究包括15名有和没有颈部疼痛临床症状的受试者。在少数椎间盘可见增宽不超过1毫米。这种增宽与表明椎间盘退行性疾病的X线征象的存在以及临床症状均无关联。
