Variables predicting prognosis following nerve mobilisation in individuals with cervicobrachial pain

Abstract

Background/AimsThe causes of cervicobrachial pain are highly variable and it is often difficult to predict patient response to multimodal treatments, such as neural mobilisation. Little research has focused on identifying subgroups of patients who may show improvement following neural mobilisation. This study aimed to identify the variables that may influence response to nerve mobilisation in individuals with cervicobrachial pain.MethodsA quasi-experimental prospective single-arm study was conducted with 50 participants. Data were collected on various potentially prognostic variables from baseline questionnaires, medical history and physical examination. Participants received 10 days of pain modulation treatment and nerve mobilisation exercises. The Neck Disability Index, Numeric Pain Rating Scale and Upper Limb Tension Test were performed before and after treatment to determine the effect of nerve mobilisation. Data were analysed using descriptive statistics, univariate correlation, multivariate stepwise logistic regression and non-parametric testing at α≤0.05.ResultsFour variables had a positive influence on treatment outcome: age <41 years, duration of symptoms ≤1 year, fasting blood glucose level ≤5.6 mmol/L (≤100 mg/dL) and systolic blood pressure ≤140 mmHg. On multiple linear regression, the presence of hypertension and diabetes were strongly associated with poor outcomes following nerve mobilisation.ConclusionsYounger individuals with normal fasting blood glucose and systolic blood pressure who have had cervicobrachial pain for less than a year are more likely to benefit from pain modulation and neural mobilisation.
