Predictors of Response to Manual Physiotherapy Using Somatosensory Profiles in Patients With Cervicobrachial Pain

During the first visit, socio-demographic data will be collected. Then, participants will be assessed using the quantitative sensory testing (QST) to evaluate the excitability of the nervous system. In addition, questionnaires and scales will be used to obtain information on the psychosocial factors involved, neuropathic pain characteristics and on the disability caused by their situation. Finally, various clinical tests will be carried out to obtain information on neck movement and irritability at closure of the intervertebral foramen, mechanosensitivity of the upper limb with neurodynamic testing and alterations in sensitivity, strength and myotatic reflexes. Also they will be asked for permission to access to their imaging tests. Once the pre-treatment data has been obtained, the manual physiotherapy and exercise treatment will begin, which aims to reduce the irritability of the nervous system. Once the treatment is completed, the initial measurements will be repeated along with a global rating of change scale to classify patients as responders vs. non-responders.
