Rotator Cuff Injuries
Rotator cuff injuries can result from various causes, including micro-trauma, wear and tear, traumatic events (like falls with outstretched hands or dislocations), and secondary dysfunctions. These injuries encompass tears, tendinitis, tendinopathy, and impingement syndrome.
Certain factors may increase your risk of rotator cuff tears, including smoking, Type 1 diabetes, joint capsule inflammation, frozen shoulder, rheumatoid arthritis, thyroid issues, and poor vascularization.
Signs of a Rotator Cuff InjuryIf you suspect a rotator cuff injury, you might experience:
Pain when reaching overhead or flexing your arm forward
Sharp pain during the injury and at night
A positive Painful Arc Sign (though not always conclusive for subacromial impingement)
Weakness in the affected muscle
Localized pain, such as in the supraspinatus
Symptoms like clicking, catching, stiffness, and crepitus
Anatomy & Biomechanics
Let's take a closer look at the anatomy and biomechanics of the rotator cuff (SITS) muscles, crucial components in shoulder function and stability.
Supraspinatus Muscle
Origin: Supraspinous fossa on the scapula
Insertion: Superior facet of the greater tubercle
Action: Abducting the humerus
Innervation: Suprascapular nerve (C5)
Infraspinatus Muscle
Origin: Infraspinous fossa on the scapula
Insertion: Middle facet of the greater tubercle
Action: Externally rotating the humerus
Innervation: Suprascapular nerve (C5-C6)
Teres minor Muscle
Origin: Middle half of the scapulae's lateral border
Insertion: Inferior facet of the greater tubercle
Action: Externally rotating the humerus (again!)
Innervation: Axillary nerve (C5)
Subscapularis muscle
Origin: Subscapular fossa on the scapula
Insertion: Lesser tubercle
Action: Internally rotating the humerus
Innervation: Upper and Lower subscapular nerves (C5-C6)
Examination and Diagnosis
A thorough shoulder examination should encompass both orthopedic and neurological assessments to accurately diagnose the extent of the injury and identify any underlying issues that may affect treatment and recovery.
Exam Demonstration Videos
Shoulder Examination - Orthopaedic Testing
This video teaches some common causes of shoulder pain and how to diagnose them using orthopaedic examination procedures.
Upper Limb Neuro Exam
The upper limb neurological examination is part of the overall neurological examination process and is used to assess the motor and sensory neurons which supply the upper limbs. This assessment helps to detect any impairment of the nervous system.
Peripheral Vascular Examination - Key Points
A peripheral vascular examination is a valuable tool for ruling out signs of vascular-related pathology. The detection and subsequent treatment of PVD can potentially mitigate cardiovascular and cerebrovascular complications.
Imaging
Advanced diagnostic imaging is essential when a patient’s history and physical examination require further clarification. These techniques are key in identifying fractures, infections, degenerative joint conditions, osteoporosis, and pathologies resistant to conservative treatment.
MRI (Magnetic Resonance Imaging) is the preferred method for shoulder imaging due to its excellent soft tissue contrast and multi-planar capabilities. It allows precise evaluation of shoulder structures like the rotator cuff tendons, muscles, labrum, and capsule, making it invaluable for detecting tears, tendinopathies, and inflammation.
Other imaging options include X-rays, which are effective for assessing bone alignment, fractures, and arthritis; CT scans for detailed views of complex fractures and joint integrity; and ultrasound, a non-invasive, real-time method for examining tendons, muscles, and soft tissues during shoulder movement.
Differential Diagnosis
Accurately diagnosing shoulder injuries requires distinguishing between various conditions. Key differentials to consider include:
Acromioclavicular Injury: Damage to the AC joint, often from impact or falls, leading to pain, swelling, and limited movement.
Adhesive Capsulitis (Frozen Shoulder): Characterized by stiffness, pain, and restricted motion due to a thickened joint capsule.
Biceps Tendonitis/Tendinopathy: Inflammation or degeneration of the biceps tendon, resulting in shoulder and upper arm pain and weakness.
Bursitis: Inflammation of the bursa, causing pain, swelling, and reduced mobility.
Calcific Tendonitis: Calcium deposits in rotator cuff tendons, leading to inflammation, pain, and limited motion.
Cervical Spine Conditions: Including cervical nerve root injury, radiculopathy, and spondylosis, often causing radiating pain, numbness, or weakness from the neck to the arm.
Glenohumeral Ligament Tears: Damage to shoulder-stabilizing ligaments, resulting in pain, instability, and potential dislocation.
Glenoid Labrum Tear: Damage to the shoulder socket’s fibrocartilaginous rim, including SLAP and Bankart lesions, with symptoms of pain, instability, and clicking.
Myocardial Infarction: A heart attack can cause referred pain to the shoulder and arm, along with chest pain and shortness of breath.
Nerve Entrapment: Compression of shoulder-adjacent nerves, leading to pain, numbness, or tingling radiating down the arm.
Osteoarthritis: Degeneration of joint cartilage, causing pain, stiffness, and reduced range of motion.
Shoulder Dislocation: The humeral head slips out of the socket, usually due to trauma, resulting in severe pain and swelling.
Subacromial Impingement: Compression of rotator cuff tendons or bursa, leading to pain, inflammation, and limited motion.
Thoracic Outlet Syndrome (TOS): Compression of nerves and blood vessels, causing pain, numbness, and weakness in the shoulder, arm, and hand.
Considering these differential diagnoses helps identify the underlying cause of shoulder injuries, guiding effective treatment planning.
Treatment Overview
The encouraging news is that 8 out of 10 rotator cuff injuries can be treated effectively without surgery. Manual therapy and exercise are often the first lines of treatment. The recovery process typically involves three phases:
Phase 1: Acute Phase
Focus on reducing pain and inflammation.
Use heat, manual therapy, and recommended medications to minimize muscle tightness and spasms.
Enhance pain-free range of motion with soft-tissue therapy, joint manipulation, and exercises.
Prevent muscle atrophy with isometric exercises and improve proprioception.
Phase 2: Intermediate Phase
Patients should have an improved range of motion, better stability, and enhanced muscle control before progressing.
Strengthen muscles with isotonic exercises and focus on dynamic stabilization.
Improve proprioception and muscle control through specialized exercises.
Continue manual therapy to reduce muscle tightness, improve blood flow, and support joint stability.
Phase 3: Advanced Phase (Athletic Training)
Ensure normal range of motion, flexibility, and shoulder blade control.
Build strength through exercises that involve changing muscle length under load.
Incorporate advanced, sport-specific exercises to enhance strength, endurance, and power.
Increase exercise intensity with more repetitions, weight, and plyometric movements.
Maintain manual therapy to optimize movement and performance.
By following these phases, most patients can achieve a full recovery without the need for surgical intervention.
Manual Therapy
Manual therapy is a hands-on approach used to evaluate, diagnose, and treat musculoskeletal injuries, including those affecting the shoulder. It plays a crucial role in shoulder injury treatment for several key reasons:
Pain Relief: Techniques such as soft tissue and joint mobilization help alleviate shoulder pain by enhancing circulation, reducing inflammation, and relaxing tight muscles and tendons.
Improved Range of Motion: Manual therapy helps restore normal movement patterns by mobilizing stiff joints and muscles, reducing the risk of further injury.
Promoting Healing: By increasing blood flow and oxygen delivery to the injured area, manual therapy accelerates the body’s natural healing processes, leading to quicker recovery.
Addressing Underlying Issues: Manual therapy can correct contributing factors like poor posture, muscle imbalances, and joint dysfunction, which may otherwise hinder recovery.
Contraindications to Manual Therapy
Before applying manual therapy, it is essential to ensure the issue is musculoskeletal. Proper patient screening is critical to avoid exacerbating serious conditions. Contraindications for shoulder manual therapy include:
Active inflammatory or septic arthritis
Signs of vascular disease or conditions mimicking MSK issues (e.g., aortic aneurysm)
Joint and ligament instability
Excessive swelling or pain
Active bone disease or malignancy
Non-mechanical causes of pain
Cervical spine pathology
Progressive neurological deficits
Visceral pain referral patterns
Fracture or dislocation
By carefully considering these contraindications, healthcare professionals can safely and effectively use manual therapy to treat shoulder injuries.

Myofascial Release
Soft tissue mobilization plays a crucial role in relieving pain and restoring function by improving the relative motion between soft tissue layers, reducing adhesions, and enhancing circulation. This technique also helps minimize inflammation, promoting better tissue health. Methods such as Motion Specific Release (MSR), myofascial release, trigger point therapy, and pin-and-stretch are commonly used to address dysfunction in soft tissues.

MSR Fascial Expansion:
MSR fascial expansion integrates modern fascia science with kinetic chain dynamics and principles of acupuncture, effectively addressing rotator cuff injuries by enhancing tissue mobility and improving shoulder function.
Osseous Mobilization
The shoulder complex is a sophisticated anatomical system consisting of the glenohumeral joint and four additional joints. Contrary to popular belief, the shoulder is not composed of just one joint. Instead, it encompasses five distinct joints that work together to facilitate movement. These specific structures must be addressed if they are affected, which often occurs in a rotator cuff injury.
Effective Shoulder Joint Mobilization - MSR Protocol - Part 1
In this video, Dr. Abelson, the developer of MSR, demonstrates highly effective shoulder joint mobilization techniques using the MSR approach. It’s important to recognize that no joint functions in isolation; restrictions or dysfunctions in one area can cause compensations elsewhere in the body. Addressing these compensations along the joint’s kinetic chain is often crucial for fully resolving a shoulder injury.
Rotator Cuff Treatment Frequency
Treatment frequency is customized based on injury severity:
Grade 1 Tear (Mild):
Initial: Weekly to bi-weekly visits for 2-3 weeks
Total: 3-6 appointments, then transition to home exercises and self-management with 1-2 follow-ups as needed.
Grade 2 Tear (Moderate):
Initial: Weekly to bi-weekly visits for 3-6 weeks
Total: 3-12 appointments, tapering off as symptoms improve, with 1-2 follow-up visits.
Grade 3 Tear (Severe/Post-Surgery):
Initial: Focus on pain management, swelling reduction, and immobilization
Rehabilitation: Begins with basic exercises and progresses to strengthening, proprioception, and sport-specific training, leading to a gradual return to full activity.
Each injury grade requires a tailored approach to ensure optimal healing and function restoration.
Rotator Cuff Exercises
Each shoulder injury is unique and requires a tailored approach. For rotator cuff injuries, a personalized exercise program should focus on three key components:
Mobility and Flexibility: Improving mobility and flexibility is essential to restore normal shoulder range of motion, alleviate pain, and prevent compensatory movements that could lead to further issues.
Strengthening: Strengthening exercises rebuild the rotator cuff muscles and surrounding structures, enhancing shoulder stability, reducing re-injury risk, and allowing a confident return to daily activities and sports.
Proprioception: Enhancing proprioception is crucial for restoring awareness of the shoulder's position and movement, improving neuromuscular control, and preventing future injuries by promoting efficient and coordinated movement patterns.
