Shoulder Pain Physiotherapy Exercises: Expert Guide from A&B Hospital Pokhara

The shoulder is the most mobile joint in the human body. That mobility is its strength and its vulnerability. Unlike the hip, which sacrifices mobility for stability through deep bony containment, the shoulder relies almost entirely on muscles, tendons, and ligaments for stability. When any component of this system is damaged or imbalanced, the result is pain, weakness, or instability that can be significantly disabling. The correct physiotherapy approach depends entirely on which structure is affected.

What Are the Most Common Shoulder Conditions Treated With Physiotherapy?

Rotator cuff impingement syndrome — also called subacromial impingement — is the most common shoulder disorder. The rotator cuff tendons (supraspinatus, infraspinatus, teres minor, subscapularis) pass through a space beneath the acromion. When this space is reduced — by poor posture, scapular dysfunction, bone spurs, or rotator cuff weakness that allows the humeral head to ride upward — the tendons are compressed with overhead movement, causing pain and inflammation.

Rotator cuff tears are partial or full-thickness tears of the cuff tendons, most commonly supraspinatus. Partial tears respond well to physiotherapy. Full-thickness large tears may require surgical repair, but physiotherapy is the correct initial management for many full-thickness tears in patients without surgical contraindications who have not been adequately rehabilitated.

Frozen shoulder (adhesive capsulitis) is a condition of idiopathic inflammation and capsular contracture of the glenohumeral joint, producing progressive pain and stiffness in a characteristic pattern. It has three phases: freezing (increasing pain and stiffness, lasting 2–9 months), frozen (plateau of stiffness with reducing pain, lasting 4–12 months), and thawing (gradually improving range). It is associated with diabetes, thyroid disease, and immobilisation.

Shoulder dislocation and instability produce a spectrum from recurrent subluxations to frank dislocations requiring manual reduction. In young athletes, recurrence risk after first dislocation is high without adequate rehabilitation.

Acromioclavicular (AC) joint injury occurs with direct falls onto the shoulder and causes localised AC joint tenderness and a step deformity in higher grades. Grades I–III are managed conservatively with physiotherapy.

How Does Physiotherapy Differ Between These Conditions?

For impingement syndrome, treatment targets scapular stabilisation, rotator cuff strengthening (particularly external rotators), and postural correction to restore the subacromial space. Overhead activities are modified during the acute phase but not avoided entirely.

For rotator cuff tears, physiotherapy strengthens the intact portions of the cuff and the scapular stabilisers to compensate for the torn muscle. The deltoid, in particular, can compensate for supraspinatus function to a significant degree with targeted strengthening.

For frozen shoulder, the approach changes by phase. In the freezing phase (high pain), gentle pendulum exercises, pain-relieving modalities, and grade I–II mobilisation are used — not aggressive stretching, which worsens inflammation. In the frozen phase, grade III–IV mobilisation and progressive stretching are introduced as pain permits. In the thawing phase, full range restoration through progressive mobilisation and strengthening is the goal.

For instability, rotator cuff strengthening and scapular stabilisation are the primary interventions, but proprioceptive training — retraining the joint’s position sense — is equally important and often neglected.

What Are 10 Key Shoulder Exercises?

1. Pendulum exercise: Lean forward supporting the body on a table with the unaffected arm. Allow the affected arm to hang freely and use body movement to swing it in small circles. Provides gentle traction and movement without active muscle contraction. Used in frozen shoulder freezing phase and post-surgical early phase.

1. External rotation with resistance band: Elbow at 90 degrees at side, resist external rotation against a band anchored to a door. Primarily trains infraspinatus and teres minor. The single most important rotator cuff exercise.

1. Internal rotation stretch: Pull the affected arm behind the back gently with a towel or strap. Stretches subscapularis and posterior capsule.

1. Doorway stretch (pectoral stretch): Arms at 90 degrees against a doorframe, step forward. Stretches anterior chest, counteracting the forward-rounded posture that contributes to impingement.

1. Wall slides: Stand facing a wall, place forearms on the wall and slide them upward. Trains serratus anterior and lower trapezius — the scapular upward rotators essential for overhead function.

1. Scapular retraction: Squeeze shoulder blades together and down, hold 5 seconds. Activates middle and lower trapezius, counteracting protraction.

1. Side-lying external rotation: Lying on the unaffected side, elbow bent to 90 degrees, lift forearm toward ceiling against gravity. A foundational rotator cuff strengthener.

1. Sidelying external rotation with dumbbell (progression): As above with light resistance. Progressively loaded rotator cuff strengthening.

1. Prone Y-T-W exercise: Lying face down on a bench or bed, raise arms in Y, T, and W positions. Trains all three parts of trapezius.

1. Single-arm dumbbell row: Supports scapular retraction strength and posterior shoulder stability. Essential for trekkers carrying heavy packs.

What Should Be Avoided During Shoulder Rehabilitation?

Avoid reaching behind the back or overhead in the acute phase of impingement or frozen shoulder unless specifically cleared by the physiotherapist. Avoid sleeping on the affected shoulder — side-sleeping on the unaffected side with a pillow supporting the affected arm reduces overnight pain.

Avoid the “painful arc” in impingement — the 60–120 degree range of abduction where tendon pinching occurs — during exercise until sufficient strength and mechanics have been restored. Avoid heavy pushing exercises (bench press, push-ups with protracted scapulae) without adequate rotator cuff activation.

What Is the Frozen Shoulder Physiotherapy Protocol in Detail?

Frozen shoulder is the most common cause of shoulder pain in the 40–60 age group and is disproportionately prevalent in patients with diabetes — highly relevant in the Pokhara region. Heat packs before treatment reduce pain and improve tissue extensibility. Grade IV mobilisation — oscillatory techniques at end of range — is applied to all restricted planes of movement. Glenohumeral and scapulothoracic mobilisation are combined. After in-clinic treatment, the patient performs a home stretching programme 3–4 times daily.

In cases that are not responding to physiotherapy, corticosteroid injection into the glenohumeral joint can provide pain control that allows physiotherapy to proceed more effectively. Hydrodilatation (injection of large volumes of fluid into the joint to stretch the contracted capsule) is a more aggressive intervention with good evidence for the frozen phase.

Timeline to full recovery is 1–3 years. Physiotherapy does not shorten the overall timeline of the disease significantly, but it reduces pain, maintains range during the process, and prevents the profound secondary deconditioning that occurs when the shoulder is protected into complete disuse.
