title: Multimodal treatment program comparing 2 different traction approaches for patients with discogenic cervical radiculopathy: a randomized controlled trial.
abstract: OBJECTIVE
  The purpose of this study was to investigate the immediate and long-term effects of a 1-year multimodal program with the addition of 2 different traction approaches on the pain, function, disability, and nerve root function in patients with discogenic cervical radiculopathy (CR). This study also attempted to identify the optimal traction angle based on the maximum recovery of the peak-to-peak amplitude of the flexor carpi radialis (FCR) H-reflex.
  
  
  METHODS
  This randomized clinical trial with one-year follow-up included a total of 216 (101 female) patients with unilateral lower discogenic CR were randomly assigned to 1 of 3 groups. The standard care group (C) received the multimodal program (pain relief methods, muscle strengthening, and thoracic spine manipulation). The ventroflexion traction group (A) received the same multimodal program as group C, with added traditional ventroflexion traction. The novel traction group (B) received the same multimodal program as group C in addition to a flexor carpi radialis (FCR) H-reflex-based traction method. Primary outcomes were the Neck Disability Index (NDI) and secondary outcomes included neck pain, arm pain, and the amplitude and latency of the H-reflex. Patients were assessed at 3 intervals (pre-treatment, 4 weeks post-treatment, and the 1-year follow-up).
  
  
  RESULTS
  The mixed linear model with repeated measures indicated a significant group × time effect in favor of the novel cervical traction group (B) for measures of NDI (F = 412.6, P < .0005), neck pain (F = 108.9, P < .0005), arm pain (F = 91.3, P < .0005), H- reflex amplitude (F = 207.7, P < .0005), and H-reflex latency (F = 58.9 P < .0005). We found that the extension position of cervical spine (5° extension) was the position that achieved the maximum improvement in the novel cervical traction method.
  
  
  CONCLUSIONS
  This preliminary study showed that a multimodal program with a novel cervical traction method added improved NDI, neck pain, arm pain, and the amplitude and latency of FCR H-reflex for a group of patients with chronic discogenic CR.
