dc.description.abstractShoulder mobility is an important clinical sign in the assessment of the shoulder joint. However, here is no gold standard measuring shoulder mobility in clinical practice. While some health care personnel use functional scales like the Constant-Murley, others use a portable goniometer, and scientists use advanced motion capture systems to measure the range of motion (ROM). Unfortunately, the Constant-Murley Scale tells nothing about the ROM as it analyses functional mobility. Although low-cost and quick to perform, a goniometer can only be used in the two dimensional area, needs trained personnel, and is related to a measurement error of 8°. Basically, visual estimation of the ROM results in the same error, but depends on the expertise of the examiner and the pain intensity of the patient. In contrast, advanced systems like X-ray machines, cinematography or Mocaps allow to analyse shoulder joint motion in the three dimensional area, resulting in a significantly smaller measurement error. However, they are time consuming, need highly trained personnel and an advanced laboratory equipment making them unsuitable for clinical use. A shoulder patient passes therefore several mobility measurement types in his course of therapy depending on the preference of his health care personnel. It would therefore be very attractive to have a low-cost, easy-to-use, three dimensional measuring device to asses shoulder mobility in applied settings. In addition, it would be very smart if anyone, even without preliminary knowledge in the field of shoulder measurements, could use this device intuitively. For this reason, smartphone applications (Apps) were developed. Since existing Apps need trained personnel, have no exercise instructions, or show incorrect measurements, the ZHAW developed a new therapy application (therapp®, available in German speaking AppStores®). The program uses the factory implemented gyroscope of the iPhone® to analyse three dimensional motions and shall allow the user to measure the own shoulder ROM without preliminary knowhow. The aim of the present study was to analyse usability of the App to identify barriers for successful application and to assess their importance regarding feasibility and ease of use. In addition, concurrent validity of therapp V-1.0.0 using an iPhone 4 versus a validated Mocap (Xsens® MVN Biomech Awinda) in an applied setting was analysed.de_CH
