This randomized controlled trial aims to evaluate the effectiveness of the "Algo(S)Therapy" Pain Neuroscience Education (PNE) program in patients with chronic musculoskeletal pain. The study will assess whether the integration of communication skills training for physiotherapists enhances the outcomes of PNE. Participants will be randomly assigned to one of three groups: (1) PNE with communication-focused delivery, (2) PNE without communication emphasis, or (3) standard- usual physiotherapy care. The primary objective is to determine whether PNE combined with enhanced communication skills leads to greater improvements in pain, function, and psychosocial outcomes compared to the other interventions.
This randomized controlled trial investigates the effectiveness of the "Algo(S)Therapy" Pain Neuroscience Education (PNE) program in the management of chronic musculoskeletal pain (CMP), with a focus on the added value of physiotherapists' communication skills. The study will be conducted in accordance with the CONSORT guidelines.
Eligible participants will be men and women aged 18 to 65 years, diagnosed with chronic musculoskeletal pain in the lumbar spine, neck, shoulder, or knee for more than 3 months, reporting a pain intensity ≥3/10 on the Numeric Pain Rating Scale (NPRS), and experiencing symptoms on most days of the week. All participants must be fluent in the Greek language. Exclusion criteria include acute pain, neurological or neuromuscular disorders, malignancy, recent surgeries or fractures within the past year, fibromyalgia, pregnancy, corticosteroid use, cognitive impairments that affect communication or questionnaire completion, or participation in other therapeutic programs during the study period.
Participants will be randomized into one of three groups:
Experimental Group 1: Participants will receive individualized PNE-based physiotherapy delivered by physiotherapists who have completed the full "Algo(S)Therapy" program, which includes both pain neuroscience and communication skills training specific to managing patients with chronic pain.
Experimental Group 2: Participants will receive the same PNE-based physiotherapy intervention, but from physiotherapists who have completed only the pain neuroscience component of the "Algo(S)Therapy" program. These therapists will not have received any training in communication skills or related modules.
Control Group will receive standard physiotherapy treatment without any exposure to PNE or communication-focused training.
All therapists in the experimental groups will have at least two year of experience treating patients with chronic musculoskeletal pain and will be selected based on performance in the "Algo(S)Therapy" training program. The intervention for all groups will last five weeks, with two sessions per week (total of 10 sessions).
The study will utilize validated outcome measures to evaluate pain, function, psychosocial variables, and therapeutic alliance. These include:
Numeric Pain Rating Scale (NPRS) Pain drawings (APDs) Central Sensitization Inventory (CSI) Pain Catastrophizing Scale (PCS) Tampa Scale for Kinesiophobia (TSK) Brief Illness Perception Questionnaire (B-IPQ) Pain Self-Efficacy Questionnaire (PSEQ) Pittsburgh Sleep Quality Index (PSQI) State-Trait Anxiety Inventory (STAI) Pain Disability Index (PDI) Working Alliance Inventory - Short Revised (WAI-SR) Satisfaction of treatment (Global Rating of Change - GroC) Days with disability (Recorded in an electronic data collection notebook) Adherence to Intervention (Recorded electronically) Adverse Effects (Recorded electronically)
Assessments will be conducted at three time points: baseline (pre-intervention), post-intervention, and 3-month follow-up. Statistical analysis will include repeated measures ANOVA to evaluate within- and between-group differences over time. The required sample size of 90 participants was calculated using G*Power, accounting for an estimated 10% dropout rate.
The main goal of this study is to determine whether the inclusion of communication training in a PNE-based physiotherapy program can significantly enhance clinical outcomes in patients with chronic musculoskeletal pain, compared to PNE alone or standard care.

The PCS evaluates negative cognitive and emotional responses to pain, including rumination, magnification, and helplessness. Scores range from 0 to 52, with higher scores indicating greater levels of pain catastrophizing. This measure helps assess the psychological effect of the intervention. |
| Baseline, Post-intervention (Week 5), and 3-Month Follow-Up |
| Tampa Scale for Kinesiophobia (TSK) | The TSK measures fear of movement or re-injury, which can limit function in individuals with chronic pain. Scores range from 17 to 68, with higher scores reflecting greater kinesiophobia. This outcome examines whether the intervention improves patients' movement confidence. | Baseline, Post-intervention (Week 5), and 3-Month Follow-Up |
| Pain Sensitivity Questionnaire (PSQ) | The PSQ assesses self-reported pain sensitivity through imagined everyday painful situations. It helps identify individuals with increased pain perception, a factor often present in chronic pain conditions. The total score ranges from 0 to 10, with higher scores indicating greater pain sensitivity. This outcome evaluates whether the intervention influences pain sensitivity levels. | Baseline, Week 5, and 3-Month Follow-Up |
| Pain Self-Efficacy Questionnaire (PSEQ) | The PSEQ assesses a patient's confidence in performing activities despite their pain. Scores range from 0 to 60, with higher scores indicating stronger pain self-efficacy. This outcome evaluates the empowering effect of the intervention. | Baseline, Week 5, and 3-Month Follow-Up |
| Brief Illness Perception Questionnaire (B-IPQ) | The B-IPQ measures patients' perceptions of their illness across cognitive and emotional dimensions. The total score ranges from 0 to 80, with higher scores indicating more negative or threatening views of their pain condition. This outcome assesses changes in illness perception related to the intervention. | Baseline, Week 5, and 3-Month Follow-Up |
| Pittsburgh Sleep Quality Index (PSQI) | The PSQI evaluates sleep quality over the past month. It generates a global score ranging from 0 to 21, where scores above 5 indicate poor sleep quality. This outcome assesses whether the intervention contributes to improved sleep in chronic pain patients. | Baseline, Week 5, and 3-Month Follow-Up |
| State-Trait Anxiety Inventory (STAI) | The STAI measures both current (state) and general (trait) anxiety. Each subscale yields a score from 20 to 80, with higher scores reflecting greater anxiety levels. This outcome helps evaluate the intervention's impact on anxiety associated with chronic pain. | Baseline, Week 5, and 3-Month Follow-Up |
| Pain Disability Index (ODI) | Pain-related disability will be assessed using the Pain Disability Index (PDI), a 7-item questionnaire that evaluates interference from pain in major life domains. Each item is scored from 0 (no disability) to 10 (total disability), with a total score range of 0-70. Higher scores indicate greater functional impairment. | Baseline, Week 5, and 3-Month Follow-Up |
| Working Alliance Inventory - Short Revised (WAI-SR) | The WAI-SR assesses the quality of the therapeutic alliance between the physiotherapist and the patient. Scores range from 12 to 84, with higher scores indicating a stronger working alliance. This measure is collected post-intervention to evaluate the interpersonal impact of the therapist's communication skills. | Week 5 (Post-intervention only) |
| Satisfaction with Treatment (Global Rating of Change - GROC) | Participants will rate their perceived overall change in condition using the Global Rating of Change (GROC) scale, which typically ranges from -7 ("a very great deal worse") to +7 ("a very great deal better"). This outcome assesses overall patient satisfaction and perceived treatment effectiveness. | Post-intervention (Week 5) and 3-Month Follow-Up |
| Pain Medication Consumption | Participants will report their use of pain medication throughout the intervention period. Data will be recorded electronically frequency. This outcome assesses whether the intervention reduces reliance on pharmacological pain management. | Weekly during the 5-week intervention and at 3-Month Follow-Up |
| Adherence to Intervention | Adherence will be tracked electronically by recording participant attendance to scheduled sessions. This outcome measures compliance with the intervention protocol. | Throughout the 5-week intervention period |
| Adverse Effects | Any adverse effects related to the intervention-such as increased pain, emotional distress, or any unexpected physical or psychological responses-will be reported by participants and recorded electronically. This outcome assesses the safety and tolerability of the interventions from a patient-reported perspective and supports real-time monitoring by the research team. | Monitored continuously throughout the 5-week intervention |
