This randomized controlled trial aims to investigate the effects of Pain Neuroscience Education and Basic Body Awareness Therapy, when added to standard physiotherapy and rehabilitation, on pain, autonomic nervous system responses, and pelvic floor muscle activity in women with chronic pelvic pain. A total of 45 women diagnosed with chronic pelvic pain will be randomly allocated into three groups: (1) standard physiotherapy and rehabilitation, (2) standard physiotherapy plus Pain Neuroscience Education, and (3) standard physiotherapy plus Basic Body Awareness Therapy. The study will assess pain intensity (algometry, NRS, SF-MPQ), pain catastrophizing, autonomic responses (electrodermal activity), pelvic floor muscle activation (EMG), and related psychological, cognitive, and body awareness parameters. Secondary outcomes will include sexual function, quality of life, and patient satisfaction. The aim is to compare two awareness-based interventions-one primarily mind-to-body (Pain Neuroscience Education) and the other body-to-mind (Basic Body Awareness Therapy)-to determine their relative and complementary effects on pain perception and physiological regulation in women with chronic pelvic pain.

|---|---|---|---|---|
| Standard Physiotherapy and Rehabilitation | Behavioral | The interventions will be conducted over 8 weeks, with sessions held twice per week. The Standard Physiotherapy and Rehabilitation program includes pelvic floor muscle relaxation, myofascial release, stretching, breathing and relaxation exercises, and aerobic training. |
| Measure | Description | Time Frame |
|---|---|---|
| Pressure Pain Threshold and Pain Tolerance | Pressure pain threshold and tolerance will be assessed using a Baseline® manual algometer. Standardized measurement points will be located in the abdominal and pelvic regions (15 points in total). Pressure will be applied perpendicularly at a rate of 1 kg/s until the participant reports the first pain sensation and maximum tolerable pain. The mean of two measurements per site will be used for analysis. Distal control points (C5-C6 zygapophyseal level, second metacarpal, and tibialis anterior muscle) will be included to evaluate widespread pressure sensitivity as an indicator of central sensitization. | Baseline and up to 8 weeks |
| Pain Intensity and Characteristics (Short Form McGill Pain Questionnaire) | Pain intensity and characteristics will be assessed using the Short Form McGill Pain Questionnaire (SF-MPQ). The SF-MPQ evaluates both sensory (11 items) and affective (4 items) dimensions of pain through 15 descriptors rated on a 4-point scale (0 = none to 3 = severe). It also includes a Visual Analog Scale (VAS) and a 6-point Likert scale assessing overall pain intensity (0 = no pain to 5 = unbearable pain). Total scores will be calculated for sensory, affective, and overall dimensions. | Baseline and up to 8 weeks |
| Pain Catastrophizing (Pain Catastrophizing Scale) | Pain catastrophizing will be assessed using the Pain Catastrophizing Scale (PCS), a 13-item self-report questionnaire developed by Sullivan et al. to measure negative cognitive and emotional responses to pain. Each item is rated on a 5-point Likert scale (0 = not at all, 4 = all the time), with total scores ranging from 0 to 52. Higher scores indicate greater levels of catastrophizing. The PCS includes three subscales: rumination, magnification, and helplessness. | Baseline and up to 8 weeks |
| Autonomic Nervous System Responses - Tonic Skin Conductance Level (SCL) | Resting tonic skin conductance level will be recorded using the Shimmer3 GSR+ device with electrodes placed on the hypothenar region. Higher SCL indicates increased sympathetic arousal. |
| Measure | Description | Time Frame |
|---|---|---|
| Pain-Related Beliefs (Pain Beliefs Questionnaire) | Pain-related cognitive beliefs will be assessed using the Pain Beliefs Questionnaire (PBQ), which evaluates individuals' beliefs about the causes, meaning, and controllability of pain. The PBQ consists of two subscales: organic beliefs (the idea that pain indicates tissue damage) and psychological beliefs (the idea that pain is influenced by emotional and mental processes). Each item is rated on a 6-point Likert scale (1 = never, 6 = always), with higher scores indicating stronger beliefs in each domain. The questionnaire will be used to assess changes in pain-related cognitions and cognitive restructuring following the interventions. |

| Pain Neuroscience Education | Behavioral | The Pain Neuroscience Education (PNE) group will receive the same physiotherapy program plus weekly educational sessions focused on pain neurophysiology, central sensitization, and cognitive reframing strategies, delivered by a physiotherapist trained in Pain Neuroscience Education. |
|
| Basic Body Awareness Therapy | Behavioral | The Basic Body Awareness Therapy (BBAT) group will receive the same physiotherapy program plus weekly body awareness sessions emphasizing postural alignment, movement control and breathing. Exercises will be practiced in supine, sitting, and standing positions to enhance body-mind awareness. All interventions will be supervised by an experienced pelvic floor physiotherapist at Istinye University. |
|
| Baseline and up to 8 weeks |
| Autonomic Nervous System Responses- Phasic Skin Conductance Response (SCR) Amplitude | Phasic SCR amplitude will be recorded during painful pressure stimuli applied at the Pfannenstiel incision point. This parameter reflects rapid sympathetic responses to pain. | Baseline and up to 8 weeks |
| Autonomic Nervous System Responses- Skin Conductance Response Frequency | The total number of phasic responses during the stimulus period will be counted to quantify response frequency. | Baseline and up to 8 weeks |
| Autonomic Nervous System Responses- Skin Conductance Response Latency | Latency from stimulus onset to the first SCR will be measured to assess autonomic response timing. | Baseline and up to 8 weeks |
| Resting Pelvic Floor Muscle Activity (Resting sEMG) (Surface Electromyography) | Resting pelvic floor muscle activity will be recorded using surface electromyography (NeuroTrac® MyoPlus PRO). Electrodes will be placed bilaterally in the perianal region. Mean resting µV value across trials will be used for analysis. | Baseline and up to 8 weeks |
| Minimum Pelvic Floor Muscle Activation (Minimum sEMG) (Surface Electromyography) | Minimum muscle activation during contraction attempts will be recorded in µV. The lowest activation value across the contraction-relaxation cycles will be used. | Baseline and up to 8 weeks |
| Maximum Voluntary Contraction of Pelvic Floor Muscles (MVC) (Surface Electromyography) | MVC will be assessed during five maximal pelvic floor contractions. Values will be expressed as percent activation relative to baseline. | Baseline and up to 8 weeks |
| Pelvic Floor Muscle Relaxation Time (Surface Electromyography) | Relaxation time will be measured as the time required for sEMG amplitude to return from peak activation to baseline following a contraction. | Baseline and up to 8 weeks |
| Baseline and up to 8 weeks |
| Pelvic Floor Symptoms (Global Pelvic Floor Bother Questionnaire) | Pelvic floor dysfunction-related symptoms will be assessed using the Global Pelvic Floor Bother Questionnaire (PFBQ). This questionnaire evaluates the severity of pelvic floor symptoms and their impact on daily life, including stress urinary incontinence, urinary frequency, urgency, urge incontinence, voiding difficulty, pelvic organ prolapse, obstructive defecation, fecal incontinence, and dyspareunia. Each symptom is answered as "Yes/No," and if "Yes," participants rate the bother level from 1 (not at all) to 5 (a lot). The total score ranges from 0 to 45, with higher scores indicating greater symptom severity or bother. | Baseline and up to 8 weeks |
| Female Sexual Function (Female Sexual Function Index) | Female sexual function will be assessed using the Female Sexual Function Index (FSFI), a validated, multidimensional questionnaire developed by Rosen et al. It consists of 19 items rated on a 5-point Likert scale and evaluates six domains: desire, arousal, lubrication, orgasm, satisfaction, and pain. Total scores range from 2.0 to 36.0, with higher scores indicating better sexual function. A cutoff score of 26.55 differentiates between normal and dysfunctional sexual function. | Baseline and up to 8 weeks |
| Depression, Anxiety, and Stress Levels (Depression Anxiety Stress Scale-21) | Depression, anxiety, and stress levels will be assessed using the Depression Anxiety Stress Scale-21 (DASS-21), a reliable 21-item self-report questionnaire developed by Lovibond & Lovibond and validated in Turkish by Yılmaz et al. (2017). The scale includes three subscales-depression, anxiety, and stress-each with seven items rated on a 4-point Likert scale (0 = did not apply to me at all to 3 = applied to me very much). Higher scores indicate greater emotional distress. Severity for each subscale is categorized as normal, mild, moderate, severe, or extremely severe. | Baseline and up to 8 weeks |
| Interoceptive Awareness (Multidimensional Assessment of Interoceptive Awareness II) | Interoceptive awareness will be evaluated using the Multidimensional Assessment of Interoceptive Awareness II (MAIA-II), developed by Mehling et al. (2018) and validated in Turkish by Özpınar et al. (2021). The MAIA-II consists of 37 items rated on a 6-point Likert scale (0 = never to 5 = always) and measures eight dimensions of interoceptive awareness, including noticing, attention regulation, emotional awareness, self-regulation, and body trust. Higher scores indicate greater interoceptive awareness. Negatively worded items (items 5-12 and 15) are reverse-scored before subscale means are calculated. | Baseline and up to 8 weeks |
| Quality of Life (WHOQOL-BREF) | Quality of life will be evaluated using the World Health Organization Quality of Life Scale-Short Form (WHOQOL-BREF) and the Pelvic Pain Impact Questionnaire (PIQ). The WHOQOL-BREF, validated in Turkish by Eser et al. (1999), consists of 27 items rated on a 5-point Likert scale and assesses four domains: physical, psychological, social, and environmental. Higher scores indicate better quality of life. | Baseline and up to 8 weeks |
| Quality of Life (Pelvic Pain Impact Questionnaire) | The PIQ, developed by Chalmers et al. (2017) and validated in Turkish by Kurt et al. (2023), is an 8-item Likert-type scale assessing the multidimensional impact of chronic pelvic pain on energy, mood, sleep, gastrointestinal function, sitting tolerance, daily activities, physical activity, and clothing. Two additional open-ended questions address sexual activity and tampon use but are not included in the total score. Higher scores reflect greater impact of pain on daily life. | Baseline and up to 8 weeks |
| Patient Satisfaction (Numeric Rating Scale) | Patient satisfaction with the treatment will be assessed using a Numeric Rating Scale (NRS). Participants will be asked to rate their overall satisfaction with the treatment on a scale from 0 to 10, where 0 indicates "not satisfied at all" and 10 indicates "completely satisfied." Higher scores reflect greater satisfaction. This subjective self-assessment will be conducted at the end of the 8-week intervention period. | After 8 weeks of intervention |
