Functional Anatomy of the Shoulder

Functional anatomy of the shoulder describes how the bones, muscles, and joints in the upper arm and trunk work together to enable movement and stability. To fully understand the problems that can affect the shoulder, it is essential to have a basic knowledge of its complex anatomy. The shoulder is not a single joint, but an articular complex composed of different components that work in synergy:

• Glenohumeral joint: It is the main joint, formed by the head of the humerus (arm bone) and the glenoid of the scapula (flat triangular bone on the back). It is one of the most mobile joints in the body, but also the least stable, given the poor congruence between the articular surfaces.
• Acromioclavicular (AC) joint: Connects the clavicle (collarbone) to the acromion, a bony projection of the scapula.
• Sternoclavicular (SC) joint: Connects the clavicle to the sternum.
• Scapulothoracic joint: It is not a true anatomical joint, but rather a gliding space between the scapula and the rib cage, crucial for shoulder movement and stability.

Around these joints, an intricate system of muscles, tendons, and ligaments ensures movement and stability. The most important are the muscles of the rotator cuff (supraspinatus, infraspinatus, teres minor, and subscapularis), which originate from the scapula and insert onto the head of the humerus, responsible for rotation and stabilization movements. Other important muscles include the deltoid, biceps, triceps, and the muscles that control the scapula (trapezius, rhomboids, levator scapulae, serratus anterior). Serous bursae, such as the subacromial bursa, reduce friction between structures.

The correct coordination of all these structures is essential for fluid and painless shoulder movement. An alteration in any of these components can lead to pain and dysfunction.

Common Causes of Painful Shoulder

Shoulder pain can arise from a wide range of conditions, often interconnected. The most frequent causes include:

Impingement Syndrome (Subacromial Impingement)

It is one of the most common causes of shoulder pain. It occurs when the rotator cuff tendons (particularly the supraspinatus) and/or the subacromial bursa are compressed between the head of the humerus and the acromion during overhead arm movements. It can be caused by structural alterations (e.g., bone spurs), muscle weakness or imbalance, or repetitive movements.

Rotator Cuff Tendinopathy (with or without tear)

Refers to inflammation (tendinitis) or degeneration (tendinosis) of the rotator cuff tendons. It can evolve into a partial or complete tear of the tendons, often as a result of acute trauma or chronic wear and tear. Pain is typically aggravated by arm movements and can also be present at rest, especially at night.

Adhesive Capsulitis (Frozen Shoulder)

A condition characterized by pain and progressive loss of active and passive shoulder mobility, due to inflammation and thickening of the joint capsule. It manifests in three phases: painful, stiffening, and resolution. The causes are not always clear, but it is more common in people with diabetes or thyroid problems.

Acromioclavicular or Glenohumeral Osteoarthritis

Osteoarthritis is a degeneration of articular cartilage. It can affect the acromioclavicular joint (often due to trauma or overuse) or, less frequently, the glenohumeral joint, causing pain, stiffness, and crepitus.

Bursitis

Inflammation of a serous bursa, such as the subacromial bursa, which serves to reduce friction between tendons and bones. Often associated with impingement or tendinopathies, it causes acute pain and tenderness to the touch.

Shoulder Instability

Occurs when the head of the humerus does not remain stably centered in the glenoid, potentially causing subluxations (partial displacements) or dislocations (complete displacements). It can be traumatic or atraumatic, and often requires specific strengthening of the stabilizing muscles.

Fractures

Fractures of the proximal humerus, clavicle, or scapula can cause intense pain and functional limitation. They require initial immobilization and careful rehabilitation.

Referred Pain

Shoulder pain can also be referred from other areas, such as the neck (cervical radiculopathy), diaphragm, or internal organs (e.g., heart problems or gallbladder issues). It is crucial to rule out these causes.

Symptoms and Diagnosis

Symptoms of a painful shoulder vary depending on the underlying cause, but the most common include:

• Pain: It can be acute or chronic, localized or radiating, and worsen with specific movements or at rest (especially at night).
• Stiffness: Difficulty moving the shoulder in all directions.
• Weakness: Difficulty lifting objects or performing movements against resistance.
• Creaking or popping: Joint noises during movement.
• Swelling or warmth: Signs of inflammation.

Accurate diagnosis is the first step towards effective treatment. A doctor (orthopedist, general practitioner) will take a medical history, perform a thorough physical examination, and may request instrumental tests such as X-rays (to evaluate bones and osteoarthritis), ultrasounds (for tendons and bursae), magnetic resonance imaging (for tendons, ligaments, cartilage, and capsule) or CT scans.

The physical therapist, after medical diagnosis, will perform a detailed functional evaluation, analyzing posture, active and passive mobility, muscle strength, scapular stability, and movement quality. This evaluation is crucial for identifying specific deficits and customizing the exercise program.

Physiotherapeutic Treatment of Painful Shoulder: A Holistic Approach

Physiotherapeutic treatment aims to reduce pain, restore mobility, improve strength and stability, and prevent recurrence. The approach is always individualized and progressive, adapted to the specific needs and phase of the patient’s condition.

Acute Phase: Pain and Inflammation Management

In this phase, the primary goal is to reduce pain and inflammation.

• Relative rest: Avoid movements that trigger pain, but without completely immobilizing the shoulder, to prevent stiffness.
• Physical therapies: Ice (cryotherapy) to reduce swelling and pain. Ultrasounds, laser therapy, TENS can be used to modulate pain and promote tissue healing.
• Passive and assisted active mobilizations: Gentle movements performed by the therapist or with the aid of a stick, to maintain mobility without stressing inflamed tissues.
• Patient education: Explanation of the condition, pain management, and advice on postures and daily activities.

Subacute Phase: Mobility and Initial Strength Recovery

Once acute pain is under control, the process of recovering full mobility and restoring muscle strength begins.

• Active and passive mobilizations: Gradually increase the range of motion.
• Stretching exercises: To stretch muscles and the joint capsule that may have shortened.
• Isometric exercises: Muscle contractions without joint movement, to begin strengthening muscles without overloading them.
• Scapular stability exercises: Strengthening of the muscles that control the scapula, fundamental for correct shoulder biomechanics.

Functional Recovery Phase: Progressive Strengthening and Motor Control

This phase focuses on restoring full strength, endurance, and motor control.

• Progressive strengthening exercises: Use of resistance bands, light weights, isotonic machines, gradually increasing load and complexity.
• Proprioceptive exercises: Improve awareness of shoulder position and movement in space, essential for dynamic stability.
• Coordination exercises: To restore fluidity and efficiency of complex movements.

Return to Activity Phase: Sport-Specific and Work-Specific

The last phase aims to prepare the patient for a full return to daily, work, or sports activities, with a minimal risk of recurrence.

• Functional exercises: Simulation of specific movements required by the patient’s activities.
• Plyometric exercises: If appropriate for sports requiring explosive movements.
• Maintenance program: Education on how to maintain achieved results and prevent future problems.

Exercises for Painful Shoulder: A Detailed Protocol

The exercise protocol must always be personalized. The following exercise categories represent a typical progression, but the intensity, frequency, and choice of exercises must be guided by your doctor or physical therapist.

Fundamental Guiding Principles:

• Listen to your body: Pain is a signal. You should never push through pain. Slight discomfort is acceptable, acute pain is not.
• Gradual progression: Increase load, repetitions, or complexity only when the previous exercise is performed without pain and with good form.
• Quality of movement: Correct execution is more important than quantity.
• Consistency: Exercises must be performed regularly to achieve lasting results.

Phase 1: Mobility and Pain (Acute/Subacute Phase)

These exercises aim to reduce pain, gently maintain or recover range of motion, and relax muscles.

• Codman’s Pendulum Exercises:

• Position: Standing, bend forward with your torso almost parallel to the floor, resting the unaffected arm on a table or chair for support. The affected arm hangs freely downwards.

• Execution: Allow the affected arm to swing gently in small circles (clockwise and counter-clockwise), back and forth, and sideways. The movement should be passive, generated by gravity and slight trunk movement, not by shoulder muscle contraction.

• Repetitions: 10-20 circles in each direction, 10-20 swings back/forth and sideways. 2-3 times a day.

• Benefits: Decompresses the joint, promotes circulation, and reduces pain.

• Passive/Assisted Rotations with a Stick:

• Position: Sitting or standing, hold a stick (or broom handle) horizontally with both hands. The affected arm grasps the stick with the palm facing up or down, depending on comfort.

• Execution:

• External Rotation: Use the healthy arm to push the stick outwards, gently rotating the affected arm away from the body. Keep the elbow of the affected arm close to your side.

• Internal Rotation: Start with the affected arm in external rotation, then use the healthy arm to pull the stick inwards, rotating the affected arm towards the body.

• Repetitions: 10-15 slow and controlled repetitions for each direction. Hold the end position for 10-15 seconds. 2-3 sets.

• Benefits: Improves rotational mobility without active effort from the rotator cuff.

• Assisted Flexion/Abduction with a Stick or Pulley:

• Position: Sitting or standing.

• Execution with a Stick: Hold the stick with both hands. Use the healthy arm to lift the stick overhead (flexion) or sideways (abduction), guiding the movement of the affected arm.

• Execution with a Pulley (if available): Sitting or standing under a pulley. Grasp the handles. Use the healthy arm to pull the rope downwards, passively lifting the affected arm.

• Repetitions: 10-15 slow and controlled repetitions. Hold the end position for 10-15 seconds. 2-3 sets.

• Benefits: Increases range of motion in flexion and abduction.

• Diaphragmatic Breathing and Relaxation Exercises:

• Position: Lying on your back with knees bent and feet flat, one hand on your abdomen and one on your chest.

• Repetitions: 5-10 minutes, several times a day.

• Benefits: Reduces muscle tension, improves posture, and promotes general relaxation.

Phase 2: Stabilization and Initial Strength (Subacute/Functional Recovery Phase)

When pain has decreased and mobility has improved, exercises are introduced to begin strengthening the rotator cuff and scapular stabilizing muscles.

• Rotator Cuff Isometrics:

• Position: Standing, with the elbow of the affected arm bent at 90 degrees and the arm close to the body.

• Execution:

• External Rotation: Push the back of your hand against a wall or door frame, holding the position for 5-10 seconds.

• Internal Rotation: Push the palm of your hand against a wall or door frame, holding the position for 5-10 seconds.

• Abduction: Push the outer side of your arm against a wall, holding the position for 5-10 seconds.

• Repetitions: 5-10 repetitions for each direction. 2-3 sets.

• Benefits: Strengthens rotator cuff muscles without joint movement, ideal for initial phases.

• Scapular Squeezes (Scapular Retraction):

• Position: Sitting or standing, with arms relaxed by your sides.

• Execution: Squeeze your shoulder blades together, as if trying to hold a pencil between them. Keep your shoulders down, avoiding shrugging them towards your ears. Hold the contraction for 5 seconds.

• Repetitions: 10-15 repetitions. 2-3 sets.

• Benefits: Strengthens the muscles that stabilize the scapula, improving posture and shoulder biomechanics.

• External Rotations with Resistance Band (Light):

• Position: Standing, with a resistance band anchored to a fixed point at elbow height. Grasp the band with the hand of the affected arm, elbow bent at 90 degrees and tucked into your side.

• Execution: Pull the band outwards, rotating your forearm away from your body. Keep your elbow still. Control the slow return.

• Repetitions: 10-15 repetitions. 2-3 sets.

• Benefits: Strengthens the external rotators of the rotator cuff, crucial for stability.

• Internal Rotations with Resistance Band (Light):

• Position: Similar to the previous exercise, but with the resistance band anchored on the opposite side of the body.

• Execution: Pull the band inwards, rotating your forearm towards your body. Keep your elbow still. Control the slow return.

• Repetitions: 10-15 repetitions. 2-3 sets.

• Benefits: Strengthens the internal rotators of the rotator cuff.

• Band Row (Light):

• Position: Sitting or standing, with a resistance band anchored to a fixed point in front of you. Grasp the band with both hands.

• Execution: Pull the band towards your body, squeezing your shoulder blades and bringing your elbows back. Keep your back straight.

• Repetitions: 10-15 repetitions. 2-3 sets.

• Benefits: Strengthens the upper back muscles and scapular retractors.

Phase 3: Advanced Strength and Motor Control (Functional Recovery/Return to Activity Phase)

This phase introduces more challenging exercises to restore full shoulder strength and dynamic control.

• Lateral and Frontal Raises (with light weights or resistance bands):

• Position: Standing, with a light weight (or resistance band) in each hand.

• Execution:

• Lateral: Slowly raise your arms laterally to shoulder height, keeping your elbows slightly bent. Control the return.

• Frontal: Slowly raise your arms forward to shoulder height, keeping your elbows slightly bent. Control the return.

• Repetitions: 10-15 repetitions. 2-3 sets.

• Benefits: Strengthens the deltoid and rotator cuff muscles for lifting movements.

• Overhead Press with Progressive Weights:

• Position: Sitting or standing, with a dumbbell in each hand at shoulder height, palms facing forward.

• Execution: Push the dumbbells upwards overhead, fully extending your arms. Control the slow return to the starting position. Start with very light weights and progress gradually.

• Repetitions: 8-12 repetitions. 2-3 sets.

• Benefits: Strengthens the deltoid, triceps, and shoulder stabilizing muscles for overhead movements.

• Dumbbell or Barbell Row:

• Position: Standing, torso slightly bent forward, knees slightly bent, back straight. Dumbbells in hand or barbell.

• Execution: Pull the dumbbells or barbell towards your abdomen, squeezing your shoulder blades and bringing your elbows back. Control the slow return.

• Repetitions: 8-12 repetitions. 2-3 sets.

• Benefits: Strengthens back muscles (lats, rhomboids, trapezius) and scapular retractors.

• Push-ups (modified or full):

• Position: On the floor, hands slightly wider than shoulders.

• Execution:

• Modified: On your knees, lower your chest towards the floor and push up.

• Full: In a plank position, lower your chest towards the floor and push up.

• Repetitions: 8-15 repetitions. 2-3 sets.

• Benefits: Strengthens chest, shoulders, and triceps, improving shoulder stability.

• Dynamic Stabilization Exercises (e.g., Plank with arm movement):

• Position: In a plank position (on elbows or hands).

• Execution: Keeping your body stable and aligned, slowly lift one arm forward or sideways, holding the position for a few seconds. Alternate arms.

• Repetitions: 5-10 lifts per arm. 2-3 sets.

• Benefits: Improves core and shoulder stability in dynamic conditions.

• Proprioceptive Exercises (e.g., on unstable surfaces):

• Position: Standing on a proprioceptive board or an unstable cushion.

• Execution: Maintain balance, then perform slow and controlled movements with the shoulder (e.g., small rotations, flexions).

• Repetitions: 30-60 seconds per side. 2-3 sets.

• Benefits: Refines neuromuscular control and dynamic shoulder stability.

Phase 4: Return to Specific Activity and Prevention

This phase is highly personalized and depends on individual needs.

• Sport-specific or work-specific exercises: If the patient practices a sport that requires complex shoulder movements (e.g., throwing, swimming, tennis), exercises simulating these movements will be introduced, with progression in intensity and speed. The same applies to work activities that require lifting, pushing, or repetitive movements.
• Plyometrics: For athletes, exercises involving muscle stretch-shortening cycles to improve power (e.g., medicine ball throws).
• Maintenance program: A lighter but regular exercise program to maintain long-term shoulder strength, flexibility, and stability.

Importance of Posture and Ergonomics

Incorrect posture and a non-ergonomic work environment can significantly contribute to shoulder pain or slow down its recovery.

• Posture: Keep shoulders relaxed and slightly back, head aligned with the spine. Avoid hunching shoulders forward.
• Ergonomics: Adjust the height of your chair, desk, and computer monitor to maintain a neutral posture. Use wrist rests and ergonomic mice. Avoid holding the phone between your shoulder and ear.
• Frequent breaks: Stand up and take short breaks to stretch and move, especially during sedentary or repetitive work.

Prevention of Recurrence

Prevention is fundamental to avoid shoulder pain from recurring.

• Maintaining the exercise program: Continue to regularly perform strengthening and mobility exercises, even after the pain has disappeared.
• Warm-up and cool-down: Always perform an adequate warm-up before physical activity and a cool-down with stretching afterwards.
• Listening to your body: Do not ignore the first signs of pain or fatigue. Early intervention can prevent the condition from worsening.
• Correct technique: Learn and apply the correct technique for sports or work movements involving the shoulder.
• Stress management: Stress can increase muscle tension and contribute to pain.

Frequently Asked Questions

Can a painful shoulder heal completely with exercises alone?

A well-structured exercise program is a cornerstone of rehabilitation for many shoulder conditions. However, complete healing may also require other interventions, such as medication, manual therapy, or, in some cases, surgical procedures, depending on the underlying cause and severity.

How long does it take to see results from exercises?

The timeline for seeing results from shoulder exercises varies significantly based on the specific condition, its severity, individual adherence to the program, and overall health. Consistent and correct execution of the prescribed exercises typically leads to gradual improvement over several weeks to months.

Can I do the exercises if I feel pain?

Exercises should generally be performed within a pain-free or minimally painful range, as excessive pain can indicate further irritation or injury. It is crucial to distinguish between discomfort from muscle work and sharp, increasing pain, and to adjust or cease exercises if significant pain occurs.

What are the signs that indicate I should consult a doctor or physical therapist?

Persistent or worsening pain, significant loss of range of motion, weakness that interferes with daily activities, or any sudden onset of severe pain or deformity warrant professional medical evaluation. These symptoms suggest the need for a thorough diagnosis and a tailored treatment plan from a doctor or physical therapist.
