Bearing in mind the limited number of studies and the low method ological quality , there are some indications that the localization ( radiation to the arms/neurologic signs ) and radiologic findings ( degenerative changes in the discs and joints ) are not associated with a worse prognosis .
A higher severity of pain and a history of previous attacks however , seems to be associated with a worse prognosis
Neck pain occurs frequently in western societies .
In the majority of cases , no specific cause can be identified .
In order to gain insight into the clinical course and prognostic factors of non-specific neck pain , a systematic review was conducted .
Pulsed high frequency (27MHz) electromagnetic therapy for persistent neck pain. A double blind, placebo-controlled study of 20 patients.
In the majority of patients with neck pain , symptoms will resolve spontaneously or quite quickly in response to therapy . However , some patients ' symptoms persist for a long period , irrespective of therapy . In this study , 20 patients with persistent ( greater than 8 weeks ) neck pain were enrolled in a double blind , placebo-controlled trial of low energy , pulsed electromagnetic therapy (PEMT)--a treatment previously shown to be effective in soft tissue injuries . For the first 3-week period , group A ( 10 patients ) received active PEMT units while group B ( 10 patients ) received facsimile placebo units . After 3 weeks , both pain ( visual analogue scale ( P less than .023 ) and range of movement ( P less than .002 ) had improved in the group on active treatment compared to the controls . After the second 3 weeks , during which both groups used active units , there were significant improvements in observed scores for pain and range of movement in both groups . PEMT , in the form described , can be used at home easily in the treatment of patients with neck pain . It is frequently successful and without side effects
