Learn vocabulary, terms, and more with flashcards, games, and other study tools. Synergy can be either flexor or extensor.They involve the action of certain muscles in combination that gives rise to abnormal pattern not useful for functional activities.
SYNERGY : Synergy patterns are abnormal ,stereotyped ,primitive ,mass movement pattern associated with spasticity and which can be triggered either reflexively and voluntarily.
The second one is the extensor synergy, which involves internal rotation of the shoulder with elbow extension and pronation of the forearm.
Assessment of poststroke motor impairment has historically focused on the ability to move within and outside of abnormal synergistic motor patterns and is typically quantified by the Fugl-Meyer Assessment (FMA). Background. Muscle synergy patterns as physiological markers of motor cortical damage.
… Start studying Abnormal Synergy Patterns. ... tion between abnormal synergy and gait was revealed. These spinal modules subserve normal motor behaviors by activating groups of muscles …
Synergy can be either flexor or extensor.They involve the action of certain muscles in combination that gives rise to abnormal pattern not useful for functional activities. Examples of common abnormal movement patterns include obligatory synergy patterns.

Table 2: Abnormal Synergies Unimpaired Limb % gait cycle classic flx/ext However, it is unclear if the voluntary, isolated movement tasks of the FMA are appropriate for evaluating walking task-specific motor control requirements because walking … It is of no surprise that the lone abnormal synergy pattern in the impaired limb follows the classic flexor /extensor synergy pattern. Cancel Unsubscribe. Extension synergy patterns include scapular protraction, shoulder adduction and internal rotation, elbow extension, forearm pronation, and wrist and finger flexion in the upper extremity; and hip extension, adduction and internal rotation, knee extension, ankle plantar flexion and inversion, and toe flexion in the lower extremity. The first one is the flexor synergy, which includes external rotation of the shoulder, flexion of the elbow, and supination of the forearm. Vincent C. K. Cheung, ... We think these muscle-synergy patterns can be used as physiological markers of the status of any patient with stroke or ... Quantification of functional weakness and abnormal synergy patterns in the lower limb of individuals with chronic stroke. Synergy patterns employed by the stroke group, but not the control group, were also investigated and are shown in Table 2.
In dynamic tasks, abnormal synergy patterns exist in the paretic upper limb between shoulder abduction with elbow flexion as well as shoulder adduction with elbow extension .

Inhibition can be described as reducing parts of movement/posture that are abnormal and interfere with normal performance. Quantification of functional weakness and abnormal synergy patterns in the lower limb of individuals with chronic stroke, Journal of NeuroEngineering and Rehabilitation, 2006, pp. Cortical damage, whether by trauma or stroke, interferes with the flow of descending signals to the modular interneuronal structures of the spinal cord. The experimental findings herein reported are aimed at gaining a perspective on the complex neural events that follow lesions of the motor cortical areas.
