Cervical Traction for Managing Neck Pain: A Survey of Physical Therapists in the United States

Use of cervical traction for managing neck pain: A cross-sectional survey of physiotherapists in India

BACKGROUND

Neck pain remains the fourth leading cause of disability and work loss, and a multimodal treatment approach is effective in reducing neck pain and disability.

PURPOSE

The purpose of this study is to examine the use of cervical traction for managing neck pain by Physiotherapists in India, including how and when the traction is used, the modes and parameters of traction, any additional interventions given with traction, and the influence of professional demographic characteristics in decision making in traction usage.

STUDY DESIGN

A cross-sectional survey.

METHODOLOGY

A random sample of approximately 2500 musculoskeletal physiotherapists was surveyed, and the data was presented in a descriptive form. Chi-square analyses were used to identify the association between responders' qualifications and traction usage.

RESULTS

From the total physiotherapist approached 18.52% (n = 463) responses were obtained, and 62% (n = 287) respondents reported that they would use traction in their clinical practice. Out of 92.3% of responders indicated using traction for radiculopathy, 78.7% of respondents used traction for patients with neck pain without radiculopathy. It is used as a combination therapy by 58.8% for radiculopathy and 52.2% for stiffness. There was no association between the responder's qualification and traction usage (χ2 = 0.707, p = 0.40). Traction is used in combination with other physiotherapeutic techniques.

CONCLUSION

Traction use was consistent with the proposed criteria identifying patients likely to benefit. However, disregarding current guidelines, physiotherapists also use traction for non-radicular neck pain. Various traction delivery modes and parameters were used within a comprehensive plan of care incorporating multiple interventions.

Effect of a Traction Exercise Neck Brace on Cervical Spondylopathy Radiculopathy: A Clinical Study and Finite Element Analysis

Traction of cervical spine is an effective method for the treatment of cervical spondylotic radiculopathy (CSR). In this study, a cervical tractor named traction exercise neck brace (TENB) was used to evaluate its effect on the patients with CSR. Forty CSR volunteers were recruited and randomly divided into two groups. One group was subjected to cervical muscle exercise with TENB under static traction condition. Another group was subjected to (JOBT) as controls. Symptoms of CSR were evaluated by the visual analogue scale (VAS) and neck disability index (NDI). Imaging characteristics were assessed by curvature of the cervical spine and size of the intervertebral foramen. A finite element (FE) analysis model of cervical spine was established by 3D reconstruction to simulate the TENB traction, which evaluates the biomechanical performance. Results showed that TENB significantly reduced scores of VAS and NDI in subjects, and this improved effect on symptoms of pain and radiculopathy is better than that of JOBT. TENB also improved the cervical curvature and enlarged intervertebral foramen at the C4-C6 level. Moreover, FE analysis found that simulated TENB traction increased the spacing of intervertebral foramen, intervertebral disc, and zygapophyseal and uncovertebral joints and changed the stress distribution on the facet joints and nucleus pulposus. This study demonstrates that TENB relieves the symptoms of CSR by adjusting structure of cervical vertebra and restoring its biomechanical performance, which may be a promising instrument in the treatment of CSR.

Effect of Caudal Traction on Mechanical Nociceptive Thresholds of Epaxial and Pelvic Musculature on a Group of Horses With Signs of Back Pain

Direct muscular attachment from lumbar vertebrae to the caudal vertebrae of the tail suggests that caudal traction, also described as a tail pull, may affect lumbar vertebral segments and/or associated soft tissues in horses. Traction is a commonly used human manual therapy technique used for pain relief and anecdotally observed to relieve pain in horses. However, research is lacking validating the efficacy of manual caudal traction on the horse. The objective of this study was to determine if caudal traction has an effect on mechanical nociceptive thresholds (MNTs) in a group of horses with clinical signs of back pain. Pressure algometry was used to measure MNTs of five bilateral anatomical sites in the epaxial and pelvic musculature of 11 horses referred to physiotherapy because of clinical signs of back pain. Measurements were recorded both before and immediately after traction. A significant difference (P ≤ .05) was identified between mean before and after caudal traction algometry measurements in all described sites. The percentage of MNT increase was highest in the thoracic region (83%) compared with the lumbar (50%) and the pelvic (52.4%) regions. These results support an effect of caudal traction in increasing MNTs in the thoracolumbar and pelvic regions in horses. Further research to determine the clinical effect of this technique is warranted.

Is Cervical Traction Effective in Chronic Nonspecific Neck Pain Patients With Unsatisfactory NSAID Control? A Nomogram to Predict Effectiveness

OBJECTIVE

In this retrospective study, our objective was to establish a nomogram to predict the effectiveness of cervical traction in young and middle-aged chronic nonspecific neck pain (CNNP) patients with unsatisfactory nonsteroidal anti-inflammatory drug (NSAID) control. For CNNP patients with unsatisfactory NSAID control, the effectiveness of cervical traction varies. Neck muscle fat infiltration and clinical features may associate with the effectiveness.

METHODS

A total of 186 suitable patients were classified into a training data set (from August 2015 to July 2018, n = 118) and a validation data set (from August 2018 to June 2019, n = 68) with time sequence. All patients were included to receive magnetic resonance imaging scan to calculate posterior cervical fat and muscle features, then undergoing unified cervical traction in an outpatient clinic. The least absolute shrinkage and selection operator (LASSO) regression model was used to select potentially relevant features to predict effectiveness possibility of cervical traction. Multivariable logistic regression analysis was used to develop the predicting model, presenting with a nomogram. The performance of the nomogram was assessed based on its calibration, discrimination, and clinical utility.

RESULTS

Through the LASSO regression model, we identified 4 predictors including sex, good exercise compliance, the ratio of the cross-sectional area (CSA) between fat and muscle on C5 level (C5 fat CSA/muscle CSA), the ratio of CSA between fat and centrum on C5 level (C5 fat CSA/centrum muscle CSA). The nomogram provided good calibration and discrimination in the training cohort, showing an area under the curve (AUC) of 0.704 (95% CI, 0.608-0.799) and good concordance between the predicted and actual probabilities with Spiegelhalter's Z-test (P = 0.835). Discrimination of the model in the validation data set was acceptable, with AUC of 0.691 (95% CI, 0.564-0.817). Decision curve analysis revealed the nomogram to be clinically useful.

CONCLUSIONS

Male sex, good exercise compliance, lower C5 fat CSA/centrum CSA, and and lower C5 fat CSA/muscle CSA could be favorable features to predict the effectiveness of cervical traction in CNNP patients with unsatisfactory NSAID control.

The Functional and Morphological Changes of the Cervical Intervertebral Disc after Applying Lordotic Curve Controlled Traction: A Double-Blind Randomized Controlled Study

The newly developed cervical lordotic curve-controlled traction (C-LCCT) appears to be an ideal method to improve the treatment outcome in patients with cervical intervertebral disc disease. The purpose of this study was to investigate the treatment outcomes of C-LCCT including the functional and morphological changes of the cervical intervertebral disc compared to traditional traction (TT) with a randomized controlled trial design. A total of 40 patients with cervical intervertebral disc disease at the C5/6 level confirmed by magnetic resonance imaging were recruited and assigned to either the C-LCCT group or the TT group. The comprehensive health status changes of the patients were recorded using pain and functional scores (Visual Analogue Scale, Oswestry Disability Index) and morphological changes (cervical lordosis, cervical central canal area) before and after the traction treatment. Both groups showed a significant improvement in pain scores after traction (p < 0.05). The functional score and morphological changes improved significantly after treatment in the C-LCCT group. However, there was no significant improvement in the TT group (p < 0.05). The C-LCCT showed significant pain, functional, and morphological improvement compared to TT. C-LCCT could be effective in improving the treatment outcomes of the traction technique in patients with cervical intervertebral disc disease.
