Plain English Summary

Background and study aims
Structural integration (SI) is a movement education and manual therapy that manipulates muscle and soft tissues to loosen tissue layers, reposition muscles, and facilitate alignment. The practitioner’s main aim is to improve the biomechanical function, increase stability, improve balance, joint mobility, and put the body into proper alignment to facilitate improved motor patterns. The sensations of SI, when processed by the brain, may result in changes in emotion, mood, and mental wellbeing.
The aim of this study is to investigate the effects of SI on muscle and on measures of mental health.

Who can participate?
People aged 30 – 60 years with myofascial pain.

What does the study involve?
Participants will be randomly placed into three groups. One group will receive 10 weekly sessions of SI, one group will receive 10 weekly sessions of massage, and one group will not receive additional treatment. Before and after the treatment period, measurements of muscle will be taken and participants will be asked to fill out questionnaires.

What are the possible benefits and risks of participating?
Structural Integration Therapy gives optimally positioned in relation to the vertical gravity line acting on it, moves with greater freedom, fluidity, efficiency and grace. Movement becomes pleasure, breathing is easier, maintaining good posture comes easily. In addition, more efficient use of muscles allows the body to preserve energy and create more sophisticated and economical movement patterns. This is manifested by a decrease in feelings of stress, mental relaxation, increased energy and joy of life.

Where is the study run from?
Opole Medical School, Poland

When is the study starting and how long is it expected to run for?

Myofascial pain, musculoskeletal disorders


This will be a multicentre interventional study evaluating the effect of Structural Integration (SI) on soft tissue elastic properties, blood perfusion and postural stability parameters in women and men. The patients qualified to participate in the study will be randomly assigned to 1 of 3 groups (using Random Allocation Software 2.0):
1. SI-treated group – 10 sessions of Structural Integration treatment
2. SI-blinded group – 10 sessions of classic massage instead of SI
3. Control group without therapy

The target group of this study will include women and men with musculoskeletal disorders.

The research procedure will consist of several stages. First, an interview will be conducted with each participant and basic data (anthropometric measures) and psychological questionnaires will be collected. Then, postural stability, blood perfusion and elastic properties of soft tissue will be measured. Then, each patient will undergo 10 SI session intervention (or not- according to their assigned group), one session a week. After 10 SI session, the patients will give another postural stability, blood perfusion and soft tissue elasticity examination.

The main outcomes will be to compare the results of postural stability (COP movement track data in mm), blood perfusion (perfusion units, PU), posture (Kineod), and soft tissue elasticity and stiffness (N/mm) before and after ten-sessions of intervention. All the participants of the project will be informed of the purpose of the study and the procedures to be conducted, and they will express their written consent for participation and processing of their data.

SI therapy and data collection will be conducted by certified therapists from Poland, Czech Republic and Italy. Moreover, all psychological questionnaires will be sent by e-mail to certified therapists from Germany, Switzerland, Great Britain, USA, Brazil and Japan affiliated in European Guild for Structural Integration (EGSI). All psychological questionnaires will be sent by e-mail to the project manager before and after 10 SI session.

10 series of the Structural Integration:
Session 1: Increase length and pliability of soft tissues on the anterior aspect of torso, allowing freer respiratory movement of ribs, of soft tissues connecting shoulder girdle to rib cage, and hips to pelvis. Areas:: Lateral aspect of hips and thigh, hamstrings, lateral and frontal aspect of shoulders, front of rib cage.
Session 2: Increase consistency of soft-tissue pliability in feet, ankles, and knees, increasing the support they provide the upper body. Areas: Feet, ankles, and legs to knee inclusive.
Session 3: Increase anterior-posterior and cephalic–caudal pliability in soft tissues of the lateral aspect of the body, left/right and anterior/posterior balance, increase independence of thorax from pelvis. Areas: Lateral aspects of body from hip to shoulder inclusive.
Session 4: Increase pliability, left/right and anterior/posterior balance of soft tissues of the medial aspect of legs and floor of pelvis. Areas: Medial aspect of legs and deep outward rotators of hip.
Session 5: Increase pliability and left/right and surface to deep balance in soft tissues spanning the anterior aspect of the pelvis and lumbar spine. Areas: Quadriceps femoris, abdominals, psoas, and iliacus.
Session 6: Increase pliability and left/right and surface to deep balance in soft tissues spanning posterior aspect from heel to midback. Areas: Posterior aspect of feet, ankles, knees, legs, hips, pelvis, sacrum, lumbar and lower dorsal vertebra.
Session 7: Increase pliability and left/right and anterior/posterior balance in soft tissues of the cranium and cervical spine. Areas: All aspects of neck and cranium including jaw.
Session 8: Increase soft-tissue pliability and left/right balance in the hands, wrists, elbows, and arms; increase biomechanical flow between upper extremities and spine. Areas: Hands, wrists, forearms, elbows, upper arm, and shoulders.
Session 9: Increase soft-tissue pliability spanning the lower extremities through hips and pelvis; increase biomechanical flow between lower extremities and spine. Areas: Feet, ankles, legs, and pelvis.
Session 10: Further optimize biomechanical flow through extremities, shoulder, and pelvic girdles to spine; increase overall uniformity of tonus. Areas: as needed to optimize biomechanical integration.
