Bicipital Tendinopathy

Upper Limb

Overview

Bicipital tendinopathy is a common overuse injury affecting the long head of biceps tendon, characterized by pain in the anterior shoulder and upper arm. It often coexists with subacromial impingement and rotator cuff dysfunction. The condition results from repetitive microtrauma, inflammatory changes, and degenerative processes within the tendon.

Pathophysiology

Bicipital tendinopathy develops through repetitive strain, excessive overhead activities, or sudden forceful contraction. The long head of biceps tendon passes through the bicipital groove and is vulnerable to compression, friction, and traction forces. Chronic irritation leads to disruption of collagen organization, mucoid degeneration, neovascularization, and inflammatory cell infiltration. Contributing factors include glenohumeral joint instability, rotator cuff weakness (particularly subscapularis), scapular dyskinesis, and tightness in adjacent structures. Impingement of the tendon within the groove during overhead movements perpetuates the inflammatory cycle.

Typical Presentation

Site

Anterior shoulder, bicipital groove, proximal arm, and sometimes referred pain to lateral forearm

Quality

Aching, sharp, clicking or snapping sensation; may describe catching or giving way

Intensity

Mild to moderate pain (3-7/10), variable with activity

Aggravating

Overhead activities, throwing, lifting heavy objects, elbow flexion against resistance, supination activities, internal rotation with adduction (Speed's test position)

Relieving

Rest, ice, anti-inflammatory medication, gentle passive range of motion, avoiding aggravating positions

Associated

Weakness in elbow flexion and supination, reduced shoulder range of motion (especially internal rotation), scapular dyskinesis, rotator cuff weakness, possible night pain if inflammatory phase is active, palpable tenderness over bicipital groove

Orthopaedic Tests

Grade C
A+ABCDModest value: a small but usable shift in probability (LR 2–5 or 0.2–0.5)
modest, supportive value.

Yergason's Test

Procedure

Patient seated, arm at the side, elbow bent to 90°, forearm pronated. Ask the patient to turn the palm up and bend the elbow against your resistance, while you palpate the bicipital groove.

Positive Finding

Pain in the bicipital groove, or the tendon felt clicking out of the groove.

Sensitivity / Specificity

43%/79%

Reference: Holtby R & Razmjou H, Arthroscopy 2004; PMID 15007311

Interpretation

A positive test adds modest support for biceps tendon involvement; a negative test does not rule it out. A click with pain suggests the tendon subluxing from the groove. Against arthroscopy, Yergason’s test was 43% sensitive / 79% specific for biceps pathology (Holtby & Razmjou 2004; LR+ 2.05).

Grade D
A+ABCDLimited value: little effect on the diagnosis on its own
limited standalone value.

Speed's Test

Procedure

Patient standing, shoulder flexed to 90°, elbow straight, forearm supinated. Apply a downward force at the forearm while the patient resists.

Positive Finding

Pain in the bicipital groove.

Sensitivity / Specificity

32%/75%

Reference: Holtby R & Razmjou H, Arthroscopy 2004; PMID 15007311

Interpretation

Adds little on its own; many other shoulder problems cause anterior pain in this position. Use it with Yergason's test, groove tenderness and the history. Against arthroscopy, Speed’s test was 32% sensitive / 75% specific for biceps pathology (Holtby & Razmjou 2004; LR+ 1.28 — weak).

AI

Biceps Palpation Test

Procedure

Patient seated, arm at the side, elbow bent to 90°. Palpate the bicipital groove on the front of the humerus while slowly rotating the arm in and out, so the groove moves under your fingers. Compare sides.

Positive Finding

Tenderness in the groove that moves with the arm as it rotates.

Interpretation

Tenderness that moves with rotation supports the biceps tendon as the source, rather than overlying tissue. Groove tenderness is also common in people without biceps problems, so compare sides.

AI

Upper Limb Tension Test (ULTT) – Median Nerve Bias

Procedure

Patient supine. With the shoulder girdle held down, abduct and externally rotate the shoulder, supinate the forearm, extend the wrist and fingers and then the elbow. Add neck side-flexion away from and towards the test side.

Positive Finding

Reproduction of the familiar anterior arm symptoms that changes with neck side-flexion.

Interpretation

A change with neck movement suggests a nerve source for the anterior arm pain rather than the biceps tendon. A negative test makes a nerve-root source less likely.

AI

O'Brien's Test (Active Compression Test)

Procedure

Patient standing. Arm raised to 90° of flexion and 10–15° across the body, elbow straight, thumb pointing down. Apply a downward force while the patient resists. Repeat with the palm facing up.

Positive Finding

Deep pain inside the shoulder in the thumb-down position that is reduced with the palm up.

Related reference: O'Brien SJ et al., Am J Sports Med 1998; PMID 9784804

Interpretation

Deep pain points to the biceps anchor and superior labrum; pain on top of the shoulder points to the acromioclavicular joint. It does not rule SLAP lesions in or out on its own. (The crank test is a different labral test.)

AI

Supination Resistance Test (Supinator Activation)

Procedure

Patient seated, elbow bent to 90°, forearm in mid-position. Ask the patient to turn the palm up against your resistance.

Positive Finding

Pain in the front of the shoulder or at the elbow crease.

Interpretation

Biceps is the main supinator with the elbow bent, so pain supports biceps involvement. Pain at the elbow crease points instead to the distal biceps tendon.

⚠ Red Flags

  • •Sudden severe pain with audible/palpable pop suggesting tendon rupture
  • •Complete loss of elbow flexion strength (full-thickness tear)
  • •Signs of infection (fever, spreading erythema, warmth)
  • •Severe unremitting night pain suggesting inflammatory arthropathy
  • •Neurological signs (numbness, tingling, weakness) suggesting nerve compromise
  • •History of trauma with severe swelling and bruising

⚡ Yellow Flags

  • •Psychosocial distress or catastrophizing about condition
  • •Work-related fear-avoidance beliefs limiting function
  • •Secondary gain factors or litigation involvement
  • •Poor coping strategies or depression affecting recovery

Osteopathic Techniques

Region

Shoulder girdle - scapula and clavicle

Technique

Soft TissueAI

Rationale

Addressing tight pectoralis minor, anterior scalene, and other accessory muscles reduces scapular dyskinesis and reduces traction on the biceps tendon. Soft tissue release improves scapular positioning and reduces impingement mechanisms.

Region

Rotator cuff muscles (infraspinatus, supraspinatus, subscapularis)

Technique

Soft TissueAI

Rationale

Direct soft tissue treatment of rotator cuff muscles, particularly subscapularis, reduces compensatory stress on biceps tendon and restores force couples necessary for normal glenohumeral mechanics.

Region

Biceps tendon and surrounding fascia

Technique

ArticulationAI

Rationale

Gentle oscillatory movements of the shoulder through pain-free ranges promote fluid movement of the tendon within the groove, reduce adhesions, and stimulate mechanoreceptor feedback without aggressive loading.

Region

Glenohumeral joint and shoulder girdle

Technique

FunctionalAI

Rationale

Functional technique addresses the pattern of restriction and facilitates proper glenohumeral rhythm and scapulohumeral coordination, reducing abnormal mechanical stress on the biceps.

Region

Upper limb fascial chains

Technique

Soft TissueAI

Rationale

Addressing myofascial restrictions in the upper limb (including biceps brachii, brachialis, and flexor pronator mass) reduces tension throughout the kinetic chain and redistributes forces away from the tendon.
