Feedforward - Joint neurology

Feedforward mechanisms, cortical plasticity and task orientation are important issues for efficient motor control. Conscious and unconscious motor processes complement each other and peripheral sensorimotor information is automatically integrated into the coordination of complex motor tasks. This creates a balanced and effective motor system.

In this way, the unconscious and fully automatically controlled feedforward motor functions of the pelvis and the scapula ensure optimal arm and leg motor functions which normally put normal strain on the spine.

In the event of dysfunctions of the hip and/or shoulder joints, the articular neurological system is responsible for an automatic and unconscious change in the feedforward motor function of the scapula (scapuladyskinesia) and pelvis (anterior tilt). 

Cortical plasticity ensures that this altered feedforward motor activity of the scapula and pelvis is automatically integrated into the coordination of complex arm and leg motor activity so that the goal of the arm movement (grasping) or leg movement (going) is maintained. As a result of this changed feedforward motor system, the spinal column is loaded compensatively differently, resulting in back pain.

Hip Spine - Shoulder Spine Syndrome

Motor compensation strategies are important to achieve motor goals despite orthopaedic or neurological insufficiencies. 

In neurologically healthy patients, motor compensation due to functional impairment of hip and/or shoulder joints can be the cause of back pain

Hip-Spine syndrome describes how a reduced function of the hip joint leads to motor compensation in the lumbar spine. Overexertion of the lumbar spine can then make it painful.

Shoulder Spine Syndrome similarly explains how a reduced function of the shoulder joint through motor compensation can lead to scapulo-thoracic and/or cervical complaints. 

Including the motor function of the hip and/or shoulder joints in the assessment of back pain leads to better diagnostics and more realistic treatment goals for exercise therapy.

Force couple

Muscles never work alone and can only be optimally challenged when other muscles are used at the same time.

PhysioNovo therefore focuses on the application of the motor principle of force couples: two equal forces triggered by muscle activity, acting parallel to each other but in opposite directions. Global stabilising muscles thus work together with global mobilisers (prime movers). Examples are the stabilising mediocaudal scapula muscles and the dynamic shoulder muscles, the stabilising lower abdominal muscles and the dynamic hip extensors. Local stabilisers (rotator cuff shoulder and hip) maintain continuous activity with low intensity in all positions of the joint area and in all directions of joint movement.

Arthromyogenic inhibition due to the articular-neurological system is reduced and the active mobility of a joint is optimised. In addition, centralising force vectors in the joint significantly increase the load-bearing capacity.

Strength training – “the key element"

Training of muscle strength means conscious activation of more or more intense activation of muscle fibres connected to the nervous system. Professional (strength) training is therefore primarily a cognitive process. Application of the principle of Force couple is an excellent way to effectively improve muscle strength.

Increases in "muscle fibrils", which are not connected to the nervous system, e.g. through special protein-rich nutrition in combination with a specific, heavy workout or doping, do lead to "muscle growth", but not to more strength. Muscle fibrils associated with nerve fibres cannot increase in number after the growth period. And extra muscle fibres created after the growth period can no longer be connected to the nervous system and therefore have no function. 

The real strength only shows itself in the (co-ordinative) performance, not in its external appearance.
