Somatocognitive Therapy in Treatment of Provoked Vestibulodynia - a Feasibility Study

Study Overview
=================
Brief Summary
-----------------
This study examines feasibility of R&D activities in the planned randomized controlled trial where effectiveness of somatocognitive therapy intervention will be compared to treatment as usual in provoked vestibulodynia.

Detailed Description
-----------------
Provoked vestibulodynia is a multifactorial, persistent pain condition, affecting young women. It represents the most common cause of pain during sexual intercourse. Existing treatment approaches are predominantly based on clinical experience, observational studies, or reports of expert committees. Although, physiotherapy is one of the most commonly recommended treatments, high quality randomized controlled trials are needed to assess its effectiveness. This is a phase I, feasibility study with the purpose of testing R&D activities for a planned full size RCT. Additionally, patients experiences with the somatocognitive therapy intervention, assessment measures and condition itself will be collected using qualitative interviews. The results will be applied to adjust time-line of the treatment, outcome measures and therapeutic approach before commencing full scale RCT.

Design Details

Primary Purpose: Other
Intervention Model: Single Group Assignment
Interventional Model Description: Three measurements time points: baseline, after treatment, and 8 months after baseline. Additionally two interviews per participant; first - between baseline and treatment ending and second after 8 months follow up
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Somatocognitive physiotherapy<br>Every participant will maximally receive 15 individual sessions of somatocognitive physiotherapy | Other: somatocognitive physiotherapy<br>* Somatocognitive physiotherapy (SCT) is a multimodal physical therapy approach that has been developed in an attempt at alleviating the burden of longstanding pain. The main foci of SCT include: (1) bodily exercises and techniques increasing body awareness, ability to relax and control muscle tension in different situations; (2) education about the vulvodynia and factors influencing pain experience; (3) coping with emotions and thoughts related to bodily experiences; and (4) structured homework assignments promoting application of the learned techniques in daily situation and gradual exposure to activities associated with pain. An important goal of SCT is to facilitate integration of new bodily habits into the patient's daily activities. The most important learning process thus occurs in the space between the treatment sessions. The therapeutic techniques are to be rehearsed in everyday situations.<br>|

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Recruitment rate | Number of eligible patients and number of recruited participants per week | 5 months | 
| Follow-up rate | The follow-up rate is measured by the percentage of participants who were followed up successfully until the 8 months follow-up | 8 months | 
| Adherence | Adherence is defined as the number of participants who fully complete the battery of self-report questionnaires, 14-day diary, biweekly forms about the received treatment and perform Tampon tests. | 8 months | 
| Evaluation of Tampon test as a primary outcome measure - score variance | Participants perform Tampon test 3 times in course of 14 days (day1, 7 and 14) at each of the 3 time points (baseline, post-treatment, 8 months after baseline), 9 scores in total. Numerical rating scale (0-10) will be used to score pain intensity. Intra-individual score variance will be estimated as difference between the min and max score at each time point for every participant. Lower variability is better. | 8 months | 
| Adverse events | If participant is pulled out of the study because somatocognitive therapy is deemed as a non-appropriate treatment (e.g. participant is instead referred to psychological counselling), such event is recorded as adverse. | 8 months | 
| Evaluation of Tampon test as a primary outcome measure - qualitative interviews | All participants are asked in individual qualitative interviews if they experience a Tampon test as a relevant instrument for assessing pain sensitivity experienced during intercourse. | 8 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Implementation and acceptability of the somatocogntive therapy intervention | Participants will be asked in qualitative interviews about their experiences with somatocogntitve therapy intervention. Global Rating of Change scale will be used to provide quantitative estimation of participants' satisfaction with the treatment effect directly after treatment and at 8 months follow-up. The scale ranges from 1 to 6. Score of 1 means that treatment helped a lot and the score of 6 means that the treatment made the condition much worse. | 8 months | 
| Evaluation of somatocognitive therapy intervention's potential to reduce pain | Changes in individual mean scores (0-10, the lower score the better) of pain experienced during tampon test between 3 measurements time points. | 8 months | 
| Evaluation of somatocognitive therapy intervention's potential to improve sexual functioning | Changes in individual scores on Female Sexual Function Index between 3 measurements time points. Scale ranges 0-36, higher score means better sexual functioning. | 8 months | 
| Evaluation of somatocognitive therapy intervention's potential to reduce psychological distress | Changes in individual scores on Hopkins Symptom Check List - 25 questions version between 3 measurements time points. Scale ranges 1-4, lower score indicates less psychological distress. | 8 months | 
| Evaluation of somatocognitive therapy intervention's potential to reduce pain catastrophizing | Changes in individual scores on Pain Catastrophizing Scale between 3 different time points. Scale ranges 0-52, the lower score represents less pain catastrophizing | 8 months |
