Comparative Study
Reliability and concurrent validity of knee angle measurement: smart phone app versus universal goniometer used by experienced and novice clinicians.
The use of goniometers to measure joint angles is a key part of musculoskeletal practice. Recently smartphone goniometry applications have become available to clinicians. This study examined the intra- and inter-measurer reliability of novice and experienced clinicians and the concurrent validity of assessing knee range of motion using a smartphone application (the Knee Goniometer App (Ockendon(©))) (KGA) and a standard universal goniometer (UG). ⋯ The Standard Error of Measurement ranged between 1.56° (0.52-2.66) for the UG and 0.62° (0.29-1.27) for the KGA. The universal goniometer and the smartphone goniometric application were reliable in repeated measures of knee flexion angles. Smaller error of measurement values for the smartphone goniometric application might indicate superiority for assessment where clinical situations demand greater precision of knee range of motion.

Case Reports
Acromio-clavicular joint cyst associated with a complete rotator cuff tear - a case report.
This case report describes a patient with an acromio-clavicular joint (ACJ) cyst, associated with a complete tear of the supraspinatus tendon, and the related arthropathy. Ultrasound was a suitable imaging modality to make the diagnosis, and rule out other pathologies. ⋯ Cyst aspiration is not a suitable treatment, due to the high likelihood of recurrence. Optimal treatment requires management of the underlying rotator cuff tear.

Randomized Controlled Trial
Show me the skin! Does seeing the back enhance tactile acuity at the back?
A growing body of literature associates musculoskeletal disorders with cortical reorganisation. One condition in which reorganisation is established and treatments that 'train the brain' are being widely used is chronic back pain. Recent evidence suggests that treatments that involve tactile training are more effective if they incorporate multisensory mechanisms, most obviously vision. ⋯ Both the second (F(3,66) = 1.00, p = 0.398) and third (t(9) = 0.969, p = 0.358) experiments suggested that seeing the back did not significantly affect tactile acuity, confirming that our initial results were likely due to chance. The principle that visual feedback improves tactile acuity at the hand does not apply to the back. These results strongly suggest that attempts to enhance tactile training by incorporating vision will not offer the benefit to treatment of back pain that has been observed for treatment of hand pain.

Reliability study. ⋯ The reliability between physical therapists and radiologist on diagnostic ultrasound of shoulder patients in primary care is borderline substantial (Kappa = 0.63) for full thickness tears only. This level of reliability is relatively low when compared with the high reliability between radiologists. More experience and training of physical therapists may increase the reliability of diagnostic ultrasound.

Health professionals are frequently interested in predicting rearfoot pronation during weight-bearing activities. Previous inconsistent results regarding the ability of clinical measures to predict rearfoot kinematics may have been influenced by the neglect of possible combined effects of alignment and mobility at the foot-ankle complex and by the disregard of possible influences of hip mobility on foot kinematics. The present study tested whether using a measure that combines frontal-plane bone alignment and mobility at the foot-ankle complex and a measure of hip internal rotation mobility predicts rearfoot kinematics, in walking and upright stance. ⋯ Greater values of varus alignment at the foot-ankle complex combined with inversion mobility at the midfoot joints and greater hip internal rotation mobility are related to greater weight-bearing rearfoot eversion. Each measure (forefoot-shank angle and hip internal rotation mobility) alone and their combination partially predicted rearfoot kinematics. These measures may help detecting foot-ankle and hip mechanical variables possibly involved in an observed rearfoot motion or posture.
