Severe restriction was defined as almost no scapular motion. Moderate restriction showed greater restriction than mild restriction and some restriction remained after the PSM maneuver. Mild restriction displayed slight restriction, although the restriction can be readily removed with the PSM maneuver. Thus, the authors defined normal scapular motion as “no restriction with passive scapular motion (PSM)”. Moves freely and fully towards the eight directions conversely, the scapula of patients with IFS displayed remarkably limited range of motion. ER, external rotation IR, internal rotation. Order to examine the level of scapular motion restriction. Holding a pillow so as to not disturb passive scapular motion. Subjects lie in the lateral decubitus position on a bed, and set the arm in a relaxed position The purposes of this study were to compare the magnitude of scapular motion between two groups of normal healthy subjects aged in their twenties (20s) and fifties (50s), and between the group of normal healthy subjects aged in their 50s and patients with IFS.Įight directions of passive scapular motion test. scapular restriction progressed with aging and restriction of the scapular motion was severely associated with patients with IFS. The authors hypothesized that a decrease on scapular motion, i.e. Additionally, such alterations of scapular kinematics are not shown to be clinically relevant in the evaluation, treatment, and prognosis of the shoulder pathologies. Ĭhanges in scapular kinematics, which are a decrease in upward rotation with aging and an increase of upward rotation in the shoulder pathologies, are conflicting reciprocally and have not been completely interpreted. Patients with IFS have shown to display increases in scapular upward rotation and on the contrary, decreases in posterior tilt in comparison with the non-affected shoulder. The prevalence of idiopathic frozen shoulder (IFS), the etiology has not been determined with any certainty, is especially higher in the population aged over 50 years old. An increase in upward rotation is revealed in patients with shoulder pathologies who are over 50 years of age. Scapular dyskinesis, winging, and alterations of scapular kinematics have been described as dysfunctions of the scapula. reported that scapular upward rotation and posterior tilt decreased with aging due to thoracic kyphosis and suggested that the regressions may lead to shoulder pathologies. Children show greater scapular upward rotation than that of adults, and conversely the angles of both upward rotation and posterior tilt decrease with aging. As an individual ages, alterations of the scapular kinematics during shoulder elevation has been well documented. The motion of the scapula is a combination of these directions, for example, which simultaneously translates towards elevation, upward rotation, posterior tilt, and internal rotation during arm elevation. The scapula moves towards 8 directions: elevation and depression upward and downward rotation anterior and posterior tilt and internal and external rotation. Proper control of the scapular position is an essential component for the functions of the shoulder joint, providing precise reach motion of the upper limb to a target in a grasping or pointing action.
