Spasticity and the influence of synergy begins to decline and the patient is able to move with less restrictions. The ease of these movements progresses from difficult to easy within this stage. 5: Spasticity continues to decline, and there is a greater ability for the patient to move freely from the synergy pattern.
Examples of common abnormal movement patterns include obligatory synergy patterns. These patterns can be described as the process of trying to perform isolated movement of a particular limb but triggering the use of other typically uninvolved muscles (when compared to normal movement) in order to achieve movement.
Obligatory synergy patterns are observed when a patient tries to make a minimal voluntary movement, or as a result of stimulated reflexes. [1] The flexion synergy for the upper extremity includes scapular retraction and elevation, shoulder abduction and external rotation, elbow flexion, forearm supination, and wrist and finger flexion.

A functional muscle synergy is defined as a pattern of co-activation of muscles recruited by a single neural command signal. [18] One muscle can be part of multiple muscle synergies, and one synergy can activate multiple muscles. Synergies are learned, rather than being hardwired, like motor programs, and are organized in a task-dependent manner.

The tonic labyrinthine reflex (TLR) is a primitive reflex found in newborn humans. With this reflex, tilting the head back (extension) while lying on the stomach causes the back to stiffen and even arch backwards, the legs to straighten, stiffen, and push together, the toes to point, the arms to straighten (not bend at the elbows and wrists, and the hands to become fisted or the fingers to curl).
