▪️ Scapular dyskinesis is a condition defined by changes in the normal resting position or dynamic movement of the shoulder blade (scapula), leading to an alteration in the coupled rhythmic motion between the scapula and the humerus.
▪️ This condition is highly prevalent and is a strong predictive factor for developing painful shoulder issues, such as subacromial impingement syndrome and adhesive capsulitis (frozen shoulder).

▪️ The most common root cause of scapular dyskinesia is a muscular imbalance between the shoulder girdle's agonist and antagonist muscles, which changes the anatomical position and coordination of the scapula.
▪️ Postural abnormalities, such as disproportionate thoracic kyphosis or cervical lordosis.
▪️ Muscle contractures, particularly tightness in the pectoralis major, pectoralis minor, or the short head of the biceps.
▪️ Lack of capsular flexibility, notably tightness in the posterior shoulder capsule.
▪️ Anatomical disruptions like clavicular fractures.
▪️ Patients typically describe a dull, insidious pain that worsens gradually over time without any specific history of trauma.
▪️ This pain can be quite severe during internal rotation and abduction of the shoulder, and is commonly triggered by reaching overhead, lifting, or even just lying on the affected side.

During a clinical examination, a practitioner will observe the patient from behind to see how the shoulder blade moves, particularly during the descending phase of an overhead reach where muscle loading is eccentric.
▪️ Dyskinesis is generally classified into three types:
🔸 𝗧𝘆𝗽𝗲 𝗜: The inferior (bottom) angle of the scapula prominently sticks out dorsally at rest. During arm motion, the inferior angle tilts backward while the top of the shoulder (acromion) tilts forward over the thorax.
🔸 𝗧𝘆𝗽𝗲 𝗜𝗜: The entire medial (inner) border of the scapula is prominent at rest and tilts backward off the thorax during movement.
🔸 𝗧𝘆𝗽𝗲 𝗜𝗜𝗜: The superior (top) border of the scapula is elevated at rest. When the patient moves their arm, the movement is often initiated by a "shoulder shrug."
🔹 𝗖𝗹𝗶𝗻𝗶𝗰𝗮𝗹 𝗗𝗶𝗮𝗴𝗻𝗼𝘀𝗶𝘀
▪️ To confirm scapular dyskinesis and its contribution to shoulder pain, clinicians often perform two corrective maneuvers:
🔸 𝗦𝗰𝗮𝗽𝘂𝗹𝗮𝗿 𝗔𝘀𝘀𝗶𝘀𝘁𝗮𝗻𝗰𝗲 𝗧𝗲𝘀𝘁 (𝗦𝗔𝗧): The clinician manually assists the scapula into an upward rotation and posterior tilt while the patient elevates their arm.
🔸 𝗦𝗰𝗮𝗽𝘂𝗹𝗮𝗿 𝗥𝗲𝘁𝗿𝗮𝗰𝘁𝗶𝗼𝗻 𝗧𝗲𝘀𝘁 (𝗦𝗥𝗧): The clinician stabilizes the medial border of the scapula while testing the patient's arm elevation strength.
▪️ If either of these maneuvers results in decreased pain and an increased range of motion, it confirms that restoring scapular mechanics will relieve the patient's symptoms.

🎯 The primary goal of conservative care is to correct the muscular imbalance pulling the shoulder blade out of alignment.
▪️ Scapular dyskinesis usually involves over-activation of the upper trapezius and levator scapulae muscles, coupled with a dangerous under-activation of the middle/lower trapezius and serratus anterior.
▪️ 𝗧𝗮𝗿𝗴𝗲𝘁𝗲𝗱 𝗦𝘁𝗿𝗲𝗻𝗴𝘁𝗵𝗲𝗻𝗶𝗻𝗴: Exercises such as prone extension, side-lying external rotation, side-lying forward flexion, and prone horizontal abduction with external rotation are used to highly activate the middle and lower trapezius.
▪️ Pushup exercises, wall slides, and shoulder elevation in the scapular plane are utilized to activate the serratus anterior while intentionally minimizing the upper trapezius.
▪️ 𝗦𝘁𝗿𝗲𝘁𝗰𝗵𝗶𝗻𝗴 𝗮𝗻𝗱 𝗠𝗼𝗯𝗶𝗹𝗶𝘇𝗮𝘁𝗶𝗼𝗻: It is vital to stretch the tight anterior muscles (pectoralis major and minor) and stretch the posterior joint capsule in a side-lying position to restore healthy glenohumeral movement.

▪️ A recent clinical series evaluated this targeted, conservative approach on three distinctly different patients: a 29-year-old weightlifter, a 58-year-old manual worker involved in sailing, and a 46-year-old manual laborer.
▪️ Following a 6-to-8-week supervised physiotherapy program based on this scapular rehabilitation algorithm, all three subjects experienced significant improvements.
▪️ They reported far less pain during day-to-day activities and showed marked improvement in standardized pain and functional scores (VAS and DASH).
