Effectiveness of a Pain Neuroscience Education and Therapeutic Exercise Program Delivered by Primary Care Physiotherapists to Patients With Chronic Nociplastic Spinal Pain
Sponsor: Distrito de Atención Primaria Sevilla
Summary
The main objective of the project is to evaluate the effectiveness, in terms of quality of life, of a therapy based on an Active Coping Protocol for Non-Cancer Chronic Pain in the Primary Care setting. This approach involves no medications or invasive procedures and is based on pain neuroscience education and physical exercise, either alone or combined with treatment targeting body schema and somatosensory disturbances. The comparison will be made against a treatment involving thermotherapy and traditional physical exercise. One of the most well-documented national primary care experiences combining pain neuroeducation and physical exercise, with a detailed methodology, was carried out by the Health System of Castilla y León (Sacyl) in Valladolid. It yielded significant results using a protocol consisting of 6 sessions of pain neuroscience education and 18 sessions of group exercise. Based on this reference study, two hypotheses are proposed: the first is that reducing the number of sessions in the Active Coping Protocol for Chronic Pain would maintain treatment effectiveness. The second hypothesis suggests the potential for improved outcomes by combining the Active Coping Protocol with body schema and somatosensory disturbance treatment. To test these hypotheses, a randomized experimental study with three parallel groups will be conducted on patients aged 18 to 70, referred to Physiotherapy from health centers in the Sevilla Health District. These patients experience daily spinal chronic pain for more than 3 months or on at least half of the days over more than 6 months, with central sensitization as the underlying cause. Effectiveness will be measured in terms of quality of life (SF-36), pain intensity (Visual Analog Scale), satisfaction level, kinesiophobia, catastrophizing, pressure pain threshold, disability index (NDI/Oswestry), medication reduction, and number of monthly medical appointments. Secondary objectives include evaluating, in both experimental groups compared to the control, the outcome variables: pain intensity, treatment adherence, kinesiophobia, catastrophizing, pressure pain threshold, descending modulation system, lumbar disability index, severity level, anxiety, sleep quality, analgesic consumption, healthcare visits, and satisfaction with care received. A sample size of 135 patients has been calculated and will be randomized into the three study groups. The control group will receive thermotherapy-electrotherapy and conventional therapeutic exercise. Experimental group 1 will follow the Active Coping Program for Chronic Pain (4 education sessions and 12 physical exercise sessions). Experimental group 2 will receive somatosensory and body schema treatment along with the Active Coping Program. The study is evaluator-blinded. Statistical analysis will be performed using SPSS version 28 and R Core Team (2023). Statistical significance will be set at p-values \<0.05. Authorization will be requested from the relevant Research Ethics Committee. The results of this study may lead to updates of existing protocols, development of guidelines and manuals for managing chronic musculoskeletal pain, ongoing training for primary care professionals, and publication in high-impact scientific journals to disseminate knowledge.

Interventions
education about pain and physical excersice
The sessions will be conducted in groups of 10 to 15 patients. * 4 pain science education sessions, each lasting 1.5 hours (6 hours), with one session per week, for 4 weeks. * 12 therapeutic physical exercise program sessions, each lasting 1 hour, to be conducted over 6 weeks (12 hours), with two sessions per week. Although the intervention is group-based, individual instructions will be given to patients. Reference will be made to the content learned in the neuroeducation sessions. The exercise dose must be adjusted to the patient's condition, keeping in mind that, due to the inhibition of the descending pain modulation system, they may experience an initial increase in pain during the first sessions, so as not to alarm the patient and prevent the activity from being discontinued. The main objective is to increase the patient's functionality, an aspect that will be constantly reinforced. The session structure will be as recommended by the American College of Sports Medicine, with se
education about pain and physical excersice with somatosensorial treatment
Patients assigned to this group will receive, in addition to the same intervention as the AADC study group "intervention type 2" (education about pain), somatosensory and body schema treatment for the changes observed in an initial assessment during the 4 weeks prior. The prescribed treatment will be repeated daily at home. To facilitate the progress of the treatment, it is recommended that a companion participate in the first session, when possible, where the daily intervention to be performed at home will be explained. If the participation of a companion is not possible, the patient will attend the Health Center's physiotherapy room once a day to be accompanied by the physiotherapist and offered the same treatment opportunities. As a control and monitoring measure, the patient will attend the physiotherapy room once a week and will be called again weekly to verify that the treatment is being performed correctly. They will also be provided with a form to record their home treatment.
Classic physiotherapy treatment with physical exercise, analgesic electrotherapy and thermotherapy
The patients will receive the usual physiotherapy treatment provided in Primary Care Physiotherapy units, supported by the current Primary Care Physiotherapy protocols of Castilla y León, since Andalusia does not currently have any published. The patient will receive 12 sessions of thermotherapy (Infrared/Microwave) and analgesic electrotherapy (analgesic Tens currents) in the painful area(s), and will be prescribed exercises recommended by the Spanish Society of Physical Medicine and Rehabilitation (SERMEF). The learning and execution of the exercises will be supervised by a Primary Care physiotherapist. The sessions will be with a frequency of 2 per week on alternate days for 6 weeks.
