Differential Diagnosis in Physical Therapy of Upper Extremity and Lower Quadrant: Summary

Screening the Shoulder and Upper Extremity: Shoulder Pain Mechanism Injury to Shoulder Fall on outstretched arm

Proximal humerus fx, rotator cuff tear, SLAP lesion AC separation, rotator cuff tear, fracture, SLAP lesion

Fall onto shoulder

Arm abducted & externally rotated

Anterior instability, subscapularis tendon tear

Traction injury SLAP lesion Fall into hyperabducted arm Inferior dislocation Falling onto point

AC lesion w/arm adducted, great tuberosity fx

NO TRAUMA: Insidious onset pain

DJD, tendonitis, frozen shoulder

Insidious onset severe pain

Branchial neuritis, shingles

Night pain

Tumor

Weakness w/out pain

Nerve injury, muscle disease, chronic rotator cuff tear

Shoulder Special Tests Impingement Syndrome • Age 40 – 60

Biceps Tendon Involvement • Yergason’s: Biceps tendon instability or tendonitis ○ Sensitivity = 74%; specificity = 58% Instability/Labrum Issues • Apprehension: Possible torn labrum or anterior instability problem ○ Sensitivity = 30–53%; specificity = 63–99% Adhesive Capsulitis 1. Acute/freezing/painful phase (typically lasts 3–9 months): Gradual onset pain at rest with sharp pain at extremes ROM, and pain at night 2. Adhesive/frozen/stiffening phase (occurs at ~4 months; lasts ~12 months): Pain starts to subside, progressive loss of glenohumeral motion in capsular pattern. Pain is apparent only at extremes ROM 3. Resolution/thawing phase (last ~1–3.5

• Pain during elevation in anterior/ lateral shoulder; worse with overhead activities, does not radiate below elbow • Painful arc: between 60-120 degrees • Weakness • Hawkins–Kennedy: Supraspinatus tendon impingement: ○ Sensitivity = 72%; specificity = 66% • Neer impingement test: Subacromial impingement: ○ Sensitivity = 79%; specificity = 53% Rotator Cuff Injury • Empty can—integrity supraspinatu: ○ Sensitivity = 41–89%; specificity = 50–90% • Drop arm sign: Rotator cuff tear ○ Sensitivity = 27%; specificity = 88% • Apley scratch test: The patient attempts to touch the opposite scapula to test range of motion of the shoulder ○ Loss of range of motion = rotator cuff problem

years): Spontaneous, progressive improvement in functional range of motion
