Glossary of terms
Methods of manual diagnostics are the main instrument in searching of localization and variants of formations pathobiomechanicalchanges. However in most guides it’s reduced to palpable assess the situation of the elements of the musculoskeletal system and analysis of active and passive movements of the joints, to palpation, painfulness and intensity of tissues and limitation of movement in it and do not taking into account its mutual interference. Clinical biomechanics so far from manual therapy, so do not promote the development of manual therapy as a science. Without denying the importance of such methods of appraisement in diagnosis of pathobiomechanical methods, I would like to mention the necessary of wide using and instrumental methods of its analyses.
Glossary of terms
The main task of glossary –is to acquaint the reader with definition using at the website.
At first there are definitions that defining biomechanics pathobiomechanical changes in static and dynamic patterns of the musculoskeletal system, methods of their diagnosis and manual therapy.
The angularmotion (rotation) – it is movement of the body, wherein all its points are rotate around the axis. According to the plane of rotation it called flexion, extension, the rotation, lateroflexion (right, left).
Linear motion (displacement) –it is movement of the body, wherein all its points are moving evenly along the axis. According to the plane of rotation it called: cranial, caudal, lateral (left and right), ventral, dorsal.
Spiral movement – it is form of movement of the body, wherein all its points moving at the same time along and around the axis. According to the plane of rotation it formed by combination: flexion/extensionswith lateraldisplacement, lateroflexion (left and right) with the ventral / dorsal displacement, rotation (left and right) with the caudal-cranial displacement.
Dextromovement – it is spiraling movementof the body, wherein rotation its points to the right accompanied by caudaldisplacement, rotation to the left – cranial. For example, flexion by lateralto the left, right by lateral extensions, lateroflexionrightbyventral, lateroflexionleft -dorsal.
Levorotatoryspiraling movement – it is spiraling movement of the body, wherein rotation of its points to the right are accompanied by cranial displacement; rotation to the left – by caudal. For example, flexion – by lateral to the right, extensions –by lateral to the left, to the right lateroflexion – by dorsal, lateroflexionto the left — by ventral.
Biomechanical servo-mechanism – is self regulation of recovering of interposition of elements of the musculoskeletal system, after finishing of the movement at the expense of natural transition a spiraling movement to another.
Musculoskeletal system – is collection ofbony(musculoskeletal), muscle (postural tonicity-force balance of antagonist muscles in different regions of spine and extremities), ligament (ligament balance of the visceral organs, capsular ligaments, joints of the spine and extremities) and membrane (balance within the vertebral and intracranial membranes) systems.
Musculoskeletal system– is set ofregions ofthe spine, extremities and pelvis designed to perform static anddynamic problems ofthe body.
Static problem – it is maintaining of the vertical position of the body through formation of optimalstaticstereotype. There are such elements of musculoskeletal system: static stereotype regional postural muscle balance, vertebral motion segment, the joints of the limbs.
The dynamic problem — it is perform of complex of hard movements through formation optimaldynamic stereotype. There are elements of musculoskeletal system forits execution: dynamic stereotype, motor patterns, phasic muscles, vertebral motion segment, and the joints of the limbs.
Optimalstaticstereotype(the optimalstatic) – it is maintaining the regularity of gravitational weight bearing regions of the spine and limbs having minimal expenditure ofmuscular contraction. Visual criteria: location of the projection of common centerof gravity 3-5 s-m ahead the axis of ankle joints, parallelism boards of the region.
Locomotive stereotype – it is combination of congenital and acquired reflexes that appeared on the basement of stereotyped repeated pulses as a manifestation of adaptation of musculoskeletal system to external and internally factors afferentinfluences of the formation of serial and parallel switching on and off of motor patterns accordingly intended target, keeping sufficiency of volume, the adequacy ofthe trajectory and power (in the absence excessive movements in the neighboring and remote regions).
Region – it is a part of the spine or extremities, designed for making some static and dynamic problems. The part of spine (cervical, thoracic,lumbar) limited by bony protrusions surrounding elements of the musculoskeletal system that formed its boards (skull, shoulder girdle, the lower edge of the chest, the wings of the pelvis) and have certain direction – as physiologicalbending (lordosis, kyphosis). Parts of the extremities (shoulder, upper arm, thigh, tibias) are limited by joints that providing it. Statistical problem – it is fixation different part of body (head, shoulders, chest), keeping intra-abdominal pressure through postural balanceof opposing muscles.

There are pathogenetic and sanogenetic changes in mechanics that are differ from each other, and performs different static and dynamic changes.
Sanogeneticbiomechanicalchanges – it is static and dynamic sanogenic reactions of organism to biomechanics inconsistency of different elements of musculoskeletal system. Static – reacts on nociceptivehyperafferentationany genesis (sinuvertebralnogo irritation, intervertebral nerves, «fall» of the patient’s body in a static, etc.) It manifests itself as fixation of biomechanics servomechanism of corresponding element of musculoskeletal system. Dynamic – reacts on decrease excitability and contractility of a muscle or muscle group. It manifests itself as substitutive including other muscle groups to accomplish the motor task.
Pathogenicchanges inbiomechanics – it is long-existingfunctionalblocks that support hypoafferentation ofpropriointero-exteroceptors, disturbance of tonicity – power balance between shortened andrelaxedmuscles , that supporting the “fall” of the patient’s body in a statistic, disturbance of excitatory processes between hypo excitability and muscle hyperexcitability, that supports the formation of an atypical motor patterns. As a results all above – listened changes of biomechanics become pathogenic reaction causing neurologicaldisorganization.
Nonoptimal statics – it is uneven gravitational burdening of spine parts and extremities, that accompanied formation of “Stopped falling” of the patient’s body in vertical position and it requiring increased energy costs of muscle contraction for maintainingthe vertical position.
