Not all patients respond positively to treatment. Classifying patients can improve decision-making. The scapular kinematic and clinical impairments can aid in classifying the patients who are more likely to respond to physical therapy treatment. Thirty-three subjects (males, 20-33 years) presenting SAIS were studied to determine altered scapular kinematics and clinical impairments. Three measurements were collected: (1) three-dimensional scapular kinematics during performing functional tasks; (2) impairment outcomes of range of motion and muscle force; and (3) self-reported measurements of pain, satisfaction, and function. All patients received 6-week (2 times per week) physical therapy treatment. Improvement with treatment was determined using the Global Rating of Change Scale. Scapular kinematics and clinical impairments were first identified by t-test in predicting improvement and then combined into a multivariate prediction method. A prediction method with three variables (Flexilevel Scale of Shoulder Function score < 41, muscle power of serratus anterior < 27.4% body weight, degree of scapular internal rotation at 30° shoulder elevation during descending arm phase in unloaded condition < 0.7°) were identified. It appears that scapular kinematics and impairment features can be used to classify subjects with SAIS in addition to self-report. Prospective validation of the proposed prediction method requires further investigation. ? 2010 Elsevier Ltd.[SDGs]SDG3adult; arm movement; arm muscle; article; body weight; clinical article; controlled study; disease association; human; joint function; joint mobility; kinematics; male; manipulative medicine; medical decision making; muscle force; muscle strength; muscle training; outcome assessment; patient coding; patient satisfaction; patient selection; physical activity; physical disability; physiotherapy; prediction; predictive validity; priority journal; range of motion; rating scale; scapula; scoring system; self report; shoulder impingement syndrome; shoulder pain; stretching exercise; task performance; treatment duration; treatment outcome; Adult; Disability Evaluation; Exercise Therapy; Humans; Male; Pain Measurement; Range of Motion, Articular; Scapula; Shoulder Impingement Syndrome; Shoulder Joint; Taiwan; Young Adultjournal article10.1016/j.math.2010.06.003206157482-s2.0-77958087604
