However, since recent investigations questioned the validity of that system [ 816 ]many results in the literature may not be reliable in terms of identification either of scapular dyskinesis and of its severity. Measuring tools Hong et al. It is perhaps time to evolve our thinking and move towards a systems-based approach.

There are also variations of scapular movement within individuals depending on the speed at which movement is performed, 8 the load used, 9 whether movement is concentric or eccentric 10 and is performed unilaterally or bilaterally 11 or even the hand dominance of the subject. In our study, raters were instructed to rate each scapula independently of the other side.

A Clinical Method for Identifying Scapular Dyskinesis, Part 1: Reliability

When unrecognised and untreated, scapular dyskinesis may cause SLAP lesions, subacromial diskinesix and injuries to cuff tendons. Similarly, the dyskinesis may not become apparent until the task becomes more complicated and involves co-ordination with the wider chain. Abstract Introduction Scapular dyskinesis is a condition responsible for alteration of the normal position and kinematics of the scapula rather than a disease.

diskinwsia University athletic training facilities. An extension arm was attached to the camera stand to obtain the superior view, and the mounting points were marked in order to maintain a consistent setup throughout the data collection process.

The coalescence of assessment and treatment techniques results in a symptoms and systems approach that is patient-centred and relevant to the functional requirements of the individual. Contact forces in the subacromial space: Test movements were based on the findings of a pilot study 17 and Johnson 18 that showed active movements with resistance more often resulted in abnormal scapular motion than static tests in those with shoulder injury. Logically, injuries affecting the neck may alter the biomechanics of the shoulder and arm; as expected, the fscapular is also true.


It can thus be found in healthy individuals or be responsible for a syndrome characterised by several symptoms esfapular objective findings, called SICK, which indicates the main features of the disease. OA Musculoskeletal Medicine Oct 18;1 2: Rehabilitation of scapular dyskinesis: J Athl Training ; It is, didkinesia, unknown whether the rehabilitation represents an effective cure also at long term.

Static measurements consists 1 infera: Dyskinesia refers to a category of movement disorders that are characterized by involuntary muscle movements, [1] including movements similar to tics or chorea and diminished voluntary movements. Biceps tenosynovitis and scapular dyskinesia. Subgroup analysis of which type of patients respond best to which type of intervention would be revealing.

Understanding the functional anatomy When glenohumeral movement occurs, the scapula must also move to allow the repositioning of the glenoid fossa thus increasing the available range of movement. September 13, Revised: It is unclear, however, whether some of these conditions are the result of the dyskinesis or the latter depends on those pathologies due to altered shoulder motion or defective muscle activation.

In a study [ 11 ]a digital inclinometer was used to measure the forward scapular posture in baseball players. The publication of the shoulder symptom modification procedure SSMP 28 signalled a paradigm shift in the way shoulder assessment was conducted. To determine the reliability of the clinical assessment, a study was carried out in asymptomatic subjects and in patients with shoulder pain [ 6 ].

In symptomatic patients with shoulder pain the scapular rhythm should be evaluated and treated. Received Oct 20; Accepted Oct The vast majority of patients with scapular dyskinesis were overhead athletes, particularly baseball, rugby, tennis and volleyball players.

The scapula is protracted and is in anteriorly tilted position secondary to tight pec minor or short head of the biceps at the insertion to the coracoid process. Through range assessment of the rotator cuff. They demonstrated that a scapular position of less upward rotation and increased internal rotation protractioncommonly seen in scapular dyskinesis, increased the area of contact of the head of the humerus with the posterior superior glenoid.

Tests were performed with volunteers grasping dumbbells according to body weight, 1. J Bone Joint Surg Am ; 94 In addition to their agonistic role specific shoulder muscles also stabilize against destabilizing forces created by other shoulder muscles but this is far from static. Focal Generalised Status epilepticus Myoclonic epilepsy.

Review of the normal ratio of glenohumeral GH to scapulothoracic ST motion analyzed by Doody et al [3] under three-dimensional analysis found that the ratio of GH to ST motion changes from 7.

Differences in scapular upward rotation between baseball pitchers and position players.

Operational Definitions and Rating Scale. However, the presence of dyskinesis was not related to shoulder symptoms. Patients or Other Participants: Observed dyskinesis may actually be disskinesia strategy to optimize certain individuals or cohorts 18 — Author information Article notes Copyright and License information Disclaimer. These weights were chosen based on pilot data indicating that athletes, including those with eecapular to moderate symptoms, can repetitively lift these amounts through their full available range of motion.

Recently, however, there has been a progressive move towards viewing the scapula as being part of a wider system of movement that is regulated and controlled by multiple factors, including the wider kinetic chain and individual patient-centred requirements.

The alteration of the normal position or motion of the scapula during coupled scapulohumeral movements[4] is the definition of dyskinesis. Amphetamines also cause a dramatic increase in choreoathetoid symptoms diskineeia patients with underlying chorea such as Sydenham’sHuntington’sand Lupus.

They concluded that measures of asymmetry in athletes do not indicate dysfunction.
