L.P., a 21-year-old collegiate swimmer, went to visit her doctor complaining of shoulder pain and a reduced range of motion in the shoulder joint. On examination, L.P. was able to achieve about 165° of shoulder flexion/elevation, with pain near the end of that range. During abduction, pain was demonstrated between about 70° and 120°, after which the patient did not feel pain. Shoulder abduction against resistance yielded pain only during the first 35° of movement. All other resisted movements were pain-free. Palpation of the shoulder only produced pain on the superior surface of the greater tubercle of the humerus. Pressure at this location also produced pain that radiated down the lateral side of L.P.'s arm. The physician told L.P. that she had tendonitis in her rotator cuff and prescribed anti-inflammatory medication, ultrasound therapy, and rest.
