Detailed explanation-1: -What Are Synergy Patterns? Coordinated muscle movements are a result of different muscle groups working together. These movement patterns are called synergies, and are responsible for muscle contraction and motions that appear smooth and controlled.

Detailed explanation-2: -The extension synergy is described as shoulder adduction (SADD) coupled with elbow extension, pronation, and variable postures at the hand, possibly including wrist extension and finger flexion (Twitchell, 1951; Brunnstrom, 1970; Radomski and Latham, 2008).

Detailed explanation-3: -Spasticity often lends to soft tissue shortening due to an over recruitment of shortened muscles because of increased stretch reflexes. This pattern of tightness is called a “synergy.”

Detailed explanation-4: -In clinical practice, the typical flexion synergy of the upper limb post-stroke includes scapula lifting and internal rotation, glenohumeral joint abduction and external rotation, elbow flexion, forearm supination or pronation, and wrist and finger flexion.
