“…Thus, such tools need to be submitted to thorough testing prior to their usage in clinical practice [6]. The use of novel clinical evaluation methods depends on the determination of the degree of inter-and intra-examiner reliability, as well as the degree of specificity in the measures of the equipment to be used [7].…”

Purpose. Goniometric smartphone applications to measure joint angles offer greater practicality and accessibility, which makes them potential alternatives to a conventional goniometer. The aim of the present study was to evaluate the intra-and interexaminer reliability in measuring the angles of the range of motion of the knee with the use of the ROM© goniometric smartphone application. Method. The total of 34 young healthy women with an at least 20° limitation in knee extension range of motion participated in the study. Angular measurements of knee flexion in the dominant leg were performed with the aid of the smartphone application by three trained examiners for the evaluation of the inter-examiner reliability. The second evaluation was carried out after a 48-hour period for the determination of the intra-examiner reliability. Conclusions. The findings reveal that the ROM© goniometric smartphone application can be considered a useful tool for the evaluation of the knee range of motion in healthy women.

“…Milanese [19)] study the intra-and interobserver consistency of three senior physiotherapy students and three experienced physicians in measuring passive range of motion in six right knees by means of a smartphone as compared with UG. Observers carried out the measurement using both UG and a smartphone app and reached similar conclusions to those of this study.…”

Purpose: Smartphones have become a staple in our society. They are essential not only for our day-to-day lives but also as a healthcare tool in the face of the emergence of a myriad of health-based applications. Analyze the reliability and concurrent validity of an iPhone app as compared with traditional goniometry.Methods: 21 subjects of our work centre, in 2016 had 4 measurements of their degree of knee flexion for a randomly chosen knee position: 2 by universal goniometry (UG) and 2 by the Goniometer-Pro (G-Pro) application. A different evaluator made each measurement. The radiographs were used as a gold standard to measure the actual knee flexion angle.Results: The difference between mean intra-group values was 3,148º (±2,669º) and 2,476º (±2,638º) for G-Pro. The difference between the mean intra-group values was 5.45º. Inter-observer consistency for UG was 0,990 and 0,993 for GPro; As regards validity, the values obtained were 0,976 for UG and 0,992 for G-Pro.Conclusions: The Goniometer-Pro app seems to be a reliable and accurate tool for determining the values of knee flexion. The values obtained are slightly more accurate than those of traditional goniometry.Implication: This study intend to promote the use of apps of systemic form in the health system, as a component integrated into the management of the health. This work not only compares the reliability of two methods of measurement, compare the reliability or validity with a gold standard, as it is the radiological measurement.

“…This demonstrates the necessity for establishing techniques that enable accurate measurement of proprioception through JPS for clinicians to identify individuals at risk of sustaining injury through proprioceptive deficit, objectively monitor pathological decline and to enable creation of specific rehabilitation programmes that both maintain and enhance proprioception in pathological and non-pathological populations [3,10,21]. Therefore, overall further evidence is clearly warranted to determine the most reliable and accurate method of JPS assessment; following recent research development, emerging techniques such as smartphone applications could offer innovative and easily applicable approaches for clinical practice [25,26].…”

“…Although 2D IMC analysis may have associated initial costs and timing restraints, as highlighted by Smith et al [4], this method has demonstrated strong reliability for JPS assessment and although further more recent research into its reliability is warranted, this could potentially offer a more evidence-based alternative for clinical practice [19,35]. Currently, emerging evidence in relation to measurement of knee joint angles through smartphone applications could offer a cost-effective and easily clinically applicable alternative method of JPS measurement; however, further research is required to ascertain its reliability [25,26]. Such technology may be used in addition to audio bio-feedback, particularly at end of range measurements.…”

Aims: Evaluate the intra-rater and inter-rater reliability of hand-held goniometry compared to image capture (IMC) in the assessment of joint position sense (JPS) in healthy participants.Methodology: Repeated-measures observational study design was undertaken with 36 asymptomatic university students of both genders aged between 18 to 45 years. JPS in the knee was assessed by two assessors over two sessions (one-week interval) using hand-held goniometry and IMC methods. Joint position sense was assessed at four target knee flexion angles. Intra-and inter-rater reliability was assessed with absolute error (AE), relative error (RE) and intra-class correlation coefficient. Findings:Inter-rater reliability for goniometry was poor to substantial (ICC: 0.00 to 0.64) and was poor to moderate (ICC: 0.00 to 0.47) for IMC. Intra-rater reliability for goniometry was poor to moderate (ICC: 0.00 to 0.42) and poor to moderate for IMC (ICC: 0.00 to 0.41). AE for goniometry ranged from 3.2° to 8.6°, with RE from 0.1°-8.3°. For IMC, AE for goniometry was 5.3° to 12.5°, with RE ranging from 0.1° to 11.1°. Principal Conclusions:Neither goniometry nor IMC appeared superior to the other in JPS assessment.Caution should be made when considering the reliability for goniometry and IMC before clinical assessment is made.
