Study Notes
Types Of Shoulder Injuries
-
Rotator Cuff Injuries:
- Tears, tendinitis, or inflammation of rotator cuff muscles/tendons.
-
Shoulder Dislocation:
- Humerus pops out of the socket, usually due to trauma.
-
Shoulder Impingement Syndrome:
- Tendons get caught between the shoulder bones, causing pain.
-
Labral Tears:
- Tear of the cartilage lining the shoulder socket.
-
Fractures:
- Breaks in the clavicle, scapula, or humerus.
-
Frozen Shoulder (Adhesive Capsulitis):
- Stiffness and pain that limits range of motion.
Symptoms Of Shoulder Injuries
-
Pain:
- Localized or radiating to the neck, arm, or upper back.
-
Weakness:
- Difficulty lifting the arm or performing overhead activities.
-
Stiffness:
- Reduced range of motion in the shoulder joint.
-
Swelling and Bruising:
- Observable in the case of acute injuries.
-
Popping or Clicking Sounds:
- During movement, indicative of tendon or joint issues.
Rehabilitation Exercises
-
Range of Motion Exercises:
- Pendulum swings, wall climbs, and external rotation with a towel.
-
Strengthening Exercises:
- Resistance band exercises (e.g., internal/external rotations, rows).
-
Stretching Exercises:
- Cross-body stretches, doorway stretches to improve flexibility.
-
Scapular Stabilization:
- Exercises focusing on shoulder blade control and strength.
-
Functional Movements:
- Gradual return to sports-specific movements or overhead activities.
Diagnosis Methods
-
Physical Examination:
- Assessment of pain, strength, and range of motion.
-
Imaging Tests:
- X-rays to check for fractures, MRIs for soft tissue injuries.
-
Ultrasound:
- Real-time imaging to evaluate soft tissue structures.
-
Arthroscopy:
- Minimally invasive procedure to visualize and sometimes treat shoulder issues.
Prevention Strategies
-
Proper Warm-Up:
- Warm-up before activities to reduce injury risk.
-
Strength and Conditioning:
- Engage in shoulder strengthening exercises regularly.
-
Technique Training:
- Employ proper techniques in sports and physical activities.
-
Avoid Overuse:
- Take breaks and split intense training into manageable sessions.
-
Flexibility Training:
- Incorporate stretching to maintain shoulder flexibility and prevent stiffness.
Types Of Shoulder Injuries
- Rotator cuff injuries are common, including tears, tendinitis, and inflammation of muscles and tendons.
- Shoulder dislocations occur when the humerus pops out of the socket, often caused by trauma.
- Shoulder impingement syndrome involves tendons getting trapped between shoulder bones, resulting in pain.
- Labral tears are injuries to the cartilage lining the shoulder socket.
- Fractures can occur in the clavicle, scapula, or humerus.
- Frozen shoulder, or adhesive capsulitis, causes stiffness and pain, restricting range of motion.
Symptoms Of Shoulder Injuries
- Pain can be localized in the shoulder or radiate to the neck, arm, or upper back.
- Weakness can make lifting the arm or performing overhead activities difficult.
- Stiffness limits the range of motion in the shoulder joint.
- Swelling and bruising are visible in acute injuries.
- Popping or clicking sounds during movement can indicate tendon or joint issues.
Rehabilitation Exercises
- Range of motion exercises include pendulum swings, wall climbs, and towel-assisted external rotation.
- Strengthening exercises utilize resistance bands to improve internal and external rotations and rows.
- Stretching exercises, like cross-body stretches and doorway stretches, increase flexibility.
- Scapular stabilization exercises focus on shoulder blade control and strength.
- Functional movements gradually reintroduce sports-specific movements or overhead activities.
Diagnosis Methods
- Physical examination assesses pain, strength, and range of motion.
- Imaging tests include X-rays to identify fractures and MRIs to detect soft tissue injuries.
- Ultrasound offers real-time imaging to evaluate soft tissue structures.
- Arthroscopy is a minimally invasive procedure used to visualize and sometimes treat shoulder problems.
Prevention Strategies
- Proper warm-up routines prior to activities reduce injury risk.
- Strength and conditioning programs, including regular shoulder strengthening exercises, are important.
- Proper technique training in sports and physical activities is crucial.
- Avoiding overuse by taking breaks and splitting intense training into manageable sessions is advised.
- Flexibility training incorporating stretching helps maintain shoulder flexibility and prevent stiffness.
Impingement Tests
- Neer Test: Pain is elicited in the anterior shoulder when the arm is passively raised while stabilizing the scapula.
- Hawkins-Kennedy Test: Pain indicates impingement of the rotator cuff when the arm is flexed to 90 degrees and internally rotated.
- Cross-body Adduction Test: Pain at the acromioclavicular joint is a positive test when the arm is moved across the body.
Special Tests For Shoulder Injuries
- Apprehension Test: Apprehension or dislocation symptoms indicate a positive test when the arm is abducted and externally rotated.
- Sulcus Sign: Downward traction on the arm reveals a noticeable sulcus below the acromion indicating instability.
- Drop Arm Test: A positive test demonstrates a rotator cuff tear when the arm drops or cannot be lowered slowly after being abducted to 90 degrees.
Shoulder Anatomy
-
Key Structures:
- Bones: Humerus, Scapula, Clavicle
- Joints: Glenohumeral joint (shoulder joint), Acromioclavicular joint (AC joint), Sternoclavicular joint (SC joint)
-
Muscles:
- Rotator cuff muscles: Supraspinatus, Infraspinatus, Teres Minor, Subscapularis
- Other muscles: Deltoid, Biceps brachii, Triceps brachii
- Nerves: The brachial plexus innervates shoulder muscles.
Range Of Motion Assessment
-
Active Range of Motion (AROM):
- Abduction: 0° to 180°
- Adduction: 0° to 30°
- Flexion: 0° to 180°
- Extension: 0° to 60°
- Internal Rotation: 0° to 70°
- External Rotation: 0° to 90°
- Passive Range of Motion (PROM): Similar values to AROM, but assessments may reveal greater limitations in conditions like frozen shoulder.
Muscle Strength Testing
-
Manual Muscle Testing (MMT): Scores range from 0 (no contraction) to 5 (normal strength).
-
Key Muscles:
- Supraspinatus: Weakness is indicated if pain occurs with arm at 90° abduction.
- Infraspinatus/Teres Minor: Strength is assessed with arm at the side, performing external rotation.
- Subscapularis: Weakness suggests injury when performing the lift-off test.
-
Key Muscles:
- Functional Testing: Strength is assessed during everyday activities (e.g., reaching overhead, pushing, pulling).
