Abstract
This work aims to connect polarization techniques with directional relations of the leaf Bidirectional Reflectance Distribution Function (BRDF) by differentiating specular and diffuse reflectance. To do this, a single leave BRDF of Coffea canephora Pierre (Coffee) was captured by a Liquid Crystal Tuneable Filter (LCTF) camera in the 460-780 nm wavelength range with a linear polarizer. The advantage of using an image of the multispectral LCTF camera is that it is able to crop surface area of a leaf, which means it can select an arbitrary size of the field of view and identify the leaf area. We have been building the automatic goniometer with LCTF camera in a laboratory for complete BRDF measurement.

Abstract
INTRODUCTION Severity of penile curvature (PC) is commonly used to select the optimal surgical intervention for hypospadias, either alone or in conjunction with other phenotypic characteristics. Despite this, current literature on the accuracy and precision of different PC measurement techniques in hypospadias patients remains limited. PURPOSE Assess the feasibility and validity of an artificial intelligence (AI)-based model for automatic measurement of PC. MATERIAL AND METHODS Seven 3D-printed penile models with variable degrees of ventral PC were used to evaluate and compare interobserver agreement in estimation of penile curvatures using various measurement techniques (including visual inspection, goniometer, manual estimation via a mobile application, and an AI-based angle estimation app. In addition, each participant was required to complete a questionnaire about their background and experience. RESULTS Thirty-five clinical practitioners participated in the study, including pediatric urologists, pediatric surgeons, and urologists. For each PC assessment method, time required, mean absolute error (MAE), and inter-rater agreement were assessed. For goniometer-based measurement, the lowest MAE achieved was derived from a model featuring 86° PC. When using either UVI (unaid visual inspection), mobile apps, or AI-based measurement, MAE was lowest when assessing a model with 88° PC, indicating that high-grade cases can be quantified more reliably. Indeed, MAE was highest when PC angle ranged between 40° and 58° for all the investigated measurement tools. In fact, among these methodologies, AI-based assessment achieved the lowest MAE and highest level of inter-class correlation, with an average measurement time of only 22 s. CONCLUSION AI-based PC measurement models are more practical and consistent than the alternative curvature assessment tools already available. The AI method described in this study could help surgeons and hypospadiology researchers to measure PC more accurately.

Abstract
OBJECTIVES Smartphone applications are available using the smartphone accelerometer to measure angles. This study compared finger joint angle measurements using a traditional goniometer (TG) versus a smartphone application (SPA) in a group of patients with Dupuytren's disease, to determine if they were equally accurate. This was a clinical measurement case series. A group of patients with Dupuytren's disease were invited to participate. MATERIAL AND METHODS The Apple iPhone 7 "Measure" application was used. Participants were asked to place their hand as flat as possible on the table in a clinic room. Each joint of the ring and little fingers was measured using the TG and the SPA. Power calculation by paired t-test determined a sample size of 25. RESULTS 28 hands were measured. The Pearson correlation coefficients for the various finger joints were: metacarpophalangeal joint (MCPJ), 0.989; proximal interphalangeal joint (PIPJ), 0.997; and distal interphalangeal joint (DIPJ), 0.977. The root mean square errors (RMSE) for the various joints were: MCPJ, 3.190; PIPJ, 2.019; and DIPJ, 1.897. Bland-Altman analysis showed the two methods to be in agreement. CONCLUSION The SPA was consistent, reliable and in agreement with a TG for assessing ring and little finger joint angles. The SPA could be used by healthcare professionals instead of a TG.

Abstract
OBJECTIVE The objective of this study is to determine the physical evaluations and assessment tools used by a group of Canadian healthcare professionals treating adults with spasticity. METHODS A cross-sectional web-based 19-question survey was developed to determine the types of physical evaluations, tone-related impairment measurements, and assessment tools used in the management of adults with spasticity. The survey was distributed to healthcare professionals from the Canadian Advances in Neuro-Orthopedics for Spasticity Congress database. RESULTS Eighty study participants (61 physiatrists and 19 other healthcare professionals) completed the survey and were included. Nearly half (46.3%, 37/80) of the participants reported having an inter- or trans-disciplinary team managing individuals with spasticity. Visual observation of movement, available range of motion determination, tone during velocity-dependent passive range of motion looking for a spastic catch, spasticity, and clonus, and evaluation of gait were the most frequently used physical evaluations. The most frequently used spasticity tools were the Modified Ashworth Scale, goniometer, and Goal Attainment Scale. Results were similar in brain- and spinal cord-predominant etiologies. To evaluate goals, qualitative description was used most (37.5%). CONCLUSION Our findings provide a better understanding of the spasticity management landscape in Canada with respect to staffing, physical evaluations, and outcome measurements used in clinical practice. For all etiologies of spasticity, visual observation of patient movement, Modified Ashworth Scale, and qualitative goal outcomes descriptions were most commonly used to guide treatment and optimize outcomes. Understanding the current practice of spasticity assessment will help provide guidance for clinical evaluation and management of spasticity.

Abstract
INTRODUCTION The degree of chordee associated with hypospadias impacts operative management. Unfortunately, poor inter-observer reliability in assessing chordee by multiple methods in vitro has been demonstrated. This variability may be related to the fact that chordee is not a discrete angle, but rather an arc-like curvature similar to that of a banana. On an attempt to improve this variability, we assessed the inter-rater reliability of a novel method of chordee measurement and compared it to measurements with a goniometer both in vitro and in vivo. MATERIALS AND METHODS In vitro assessment of curvature was performed using 5 bananas. In vivo chordee measurement was performed during 43 hypospadias repairs. On in vitro and in vivo cases, chordee was assessed independently by faculty and resident physicians. Angle assessment was performed in a standard manner with a goniometer and with a smartphone app using ruler measurements of the length and width of the arc (Summary Figure). The proximal and distal aspect of the arc to be measured was marked on the bananas, whereas the penile measurements were taken from the penoscrotal to the sub-coronal junctions. RESULTS In vitro banana assessment demonstrated strong intra- and inter-rater reliability for length (0.89 and 0.88, respectively) and width measurements (0.97 and 0.96). The calculated angle demonstrated an intra- and inter-rater reliability of 0.67 and 0.67. The banana goniometer/protractor measurements were weak with an intra-rater and inter-rater reliability of 0.33 and 0.21. With hypospadias chordee, the inter-rater reliability was strong for length and width measurements (0.95 and 0.94) and 0.48 for calculated angle. The inter-rater reliability of the goniometer angle was 0.96. Further assessment of inter-rater goniometer reliability was performed relative to degree of chordee as characterized by faculty. The inter-rater reliability for ≤15°, 16-30, and ≥30° was 0.68 (n = 20), 0.34 (n = 14), and 0.90 (n = 9), respectively. When the goniometer angle was classified as ≤15, 16-30, or ≥30° by one physician, it was classified outside of this range by the other physician 23%, 47%, and 25% of the time, respectively. DISCUSSION Our data demonstrate significant limitations of the goniometer for assessing chordee in vitro and in vivo. We were unable to demonstrate significant improvement in chordee assessment using arc length and width measurements to calculate radians. CONCLUSIONS Reliable and precise techniques for measuring hypospadias chordee remain elusive and draw into question the validity and usability of management algorithms employing discrete values.

Abstract
Background: Reliable methods for measuring range of motion is important for hand therapists. Currently, there is no gold standard for the measurement of thumb metacarpophalangeal joint (MCPJ) hyperextension. We hypothesised that visual and goniometric measurements of thumb MCPJ hyperextension vary greater than 10° from radiographic measurements, and between observers. Methods: Twenty-six fresh-frozen hands were measured by a senior orthopaedic resident and fellowship trained hand surgeon. Passive thumb MCPJ hyperextension was measured by visual estimation, goniometry and axis measurement on a lateral thumb radiograph. Raters were blinded to each other's and their own prior measurements. Descriptive statistics were recorded for measurement type and inter-observer agreement using a two-way intra-class correlation coefficient (ICC). Intra-observer agreement was calculated using concordance correlation coefficient (CCC). Bland-Altman plots identified trends, systemic differences or potential outliers. Results: Mean measurements for both raters were similar for visual estimation and radiographic measurements. Mean goniometric measurements were twice as high for Rater B, and closer to radiographic measurements. For both raters, mean radiographic measurements were 10° greater than the other two methods. For inter-rater agreement, measurements were within 10° most frequently with radiographic measurement, then visual estimates, and least by goniometer measurements. Rater B had better agreement comparing visual and goniometric to radiographic measurements. Conclusions: Radiographic measurement has the best inter-observer agreement and precision for evaluating passive thumb MCPJ hyperextension, especially considering adjunct corrective procedures when performing a soft-tissue basal joint arthroplasty. Rater experience improves precision, but there is still poor agreement between visual estimates and goniometer measurements compared to radiographic measurements, as the former two underestimate hyperextension by 10°. Development of a standard method of clinical measurement is needed to improve reliability.

Abstract
The aim was to compare the morbidity of shoulder function following modified radical neck dissection with and without Pectoralis Major Myocutaneous muscle flap (PMMC) harvest in head and neck cancer patient to determine the effect of PMMC flap harvest on shoulder function and also to determine the effect of physiotherapy. Materials and methods: Prospective study involving two groups study group of 20 patients with MRND, with PMMC flap reconstruction as part of head and neck cancer surgery and control group of 20 patients who had undergone MRND(IJV & SAN sparing) without PMMC flap in same period were included. All patients were assessed at 3rd and 6th month following completion of surgery using subjective (Shoulder Disability Questionnaire) and objective (goniometer and manual muscle testing) parameters. 40 patients were included in the study, 33 (82.5%) male and 7 (17.5%) female with a mean age of 49 years with stage III/IV carcinoma In Group-1 and Group-2 the shoulder disability decreased significantly after physiotherapy intervention and also at 6thmonth postoperatively both groups showed improvements in shoulder range of motion and muscle strength. Harvesting of PMMC flap does not intensify the morbidity of shoulder which is common in RND and during MRND. A regimen of home-based exercises and patient education are effective tools to reduce shoulder disability and improving shoulder function.

Abstract
INTRODUCTION Correction of penile curvature or "chordee" is a major component in the management of hypospadias. Accurate assessment and management of penile curvature influence both short- and long-term outcomes of surgery. AIM OF THE STUDY The objective of this study is to investigate the accuracy of eyeball measurement and how does it compare to objective measurement by standard goniometry (SG) and smartphone app goniometry (AG). MATERIALS AND METHODS A Dropbox file request link was shared with paediatric urologists on various social media platforms requesting participants to upload a picture of their index finger showing what they thought 30 degrees of curvature look like using their proximal inter phalangeal joint as the point of maximal curvature., The images were assessed using SG to measure the angle of curvature. The images were also assessed using AG by the principal investigator, a physician, a scrub nurse and a paediatric urology consultant., Statistical analysis was performed using SPSS statistics software version 26 (Armonk, NY: IBM Corp). A one sample t-test and a one-way chi squared test were used to evaluate significant frequency differences. Pearson correlation was used to compare AG measurements to test intra- and inter-observer reliability and to compare AG measurements vs SG measurements. Assuming 5-degree variability in goniometer measurements and 2-degree difference between the sample and population, the number of participants needed was calculated to be 49. RESULTS Fifty-two responses were received.32.7% of respondents simulated 30° accurately (17/52). A significant proportion (23/52, 44.2%) overrepresented the degree of curvature and 23.1% (12/52) underrepresented it (p = 0.01). Compared with objective measures, eyeball estimates differed by an average of 10° ± 1.5 SE. Measurements obtained by AG were comparable to measures obtained by SG and showed excellent intra-observer and inter-observer correlation (R = 0.983, P < 0.001). DISCUSSION We demonstrated a significant discrepancy between eyeball assessment of curvature and objective measurements in a cohort of hypospadiologists. This can be very relevant to intraoperative decision making. The limitation of the study is the use of a simulated model rather than assessment of curvature in patients with hypospadias. Another limitation is the lack of standardization of the way the pictures were taken. CONCLUSION We demonstrated a tendency among hypospadiologists to overestimate or underestimate curvature by an average of 10° on eyeball assessment. The use of App Goniometry shows excellent interobserver reliability and is comparable to standard goniometry in curvature assessment.

Abstract
STUDY DESIGN Clinical measurement. INTRODUCTION Wrist range of motion (ROM) is considered the universal measurement of success for both surgical and non-surgical treatments. A goniometer can be challenging for an individual to use by themselves, whereas the Dartfish app can analyze and provide immediate feedback to monitor and evaluate patients' kinematic changes during recovery after injury. PURPOSE OF STUDY To establish the validity and reliability of the Dartfish app measuring ROM to be used in clinical applications. METHODS Twelve healthy participants, (18-25 yrs) , with no previous history of wrist injuries, were recruited for this study. Flexion/extension, radial/ulnar deviation, and supination/pronation range of motion measures were collected using a goniometer (two-arm) and Dartfish video analysis. Statistical analyses, such as t-tests and the Pearson correlation coefficient, as well as reliability analyses, such as intraclass correlation coefficient (ICC) and Bland-Altman plots, were performed. RESULTS There was no significant difference between the goniometer and Dartfish ROM measurements except for ulnar deviation. The concurrent validity showed nearly perfect correlations between examiners using Dartfish with r-values in the range 0.90-0.99, and between examiner2 and the goniometer showed medium, large, and very large correlations since the values were in the range 0.418-0.829. The ICC for test-retest reliability had an excellent agreement that ranged from 0.993-0.999, and the ICC values for inter-observer reliability had good and excellent agreement, which were in the range 0.893-0.997. CONCLUSION Overall, the results demonstrated that the Dartfish app was a reliable and valid method to measure wrist and forearm ROM. A patient would be able to easily record their own ROM measurement videos and track their progress during their recovery without the need of their physician to track their progress.

Abstract
PURPOSE To determine the effect of a 7-week Hatha yoga intervention on hamstrings flexibility using a digital goniometer. It was hypothesized that hamstring flexibility will increase in a young healthy adult population. METHODS Thirty-one college-aged males and females (Mage= 21 ± 2.62) years participated in 110 minutes twice per week for a 7-week progressive yoga intervention. Pre and post-test measurements were taken to determine hamstring flexibility on the right and left leg using a digital goniometer. RESULTS A paired samples t-test indicated a significant difference in the pre and post-test on hamstring flexibility (p < .05). Results for the right leg pre-test (t(30) = -6.64, p <0.05, 95% CI (-6.14, -3.25), d = 0.77. p < 0.05 as well as a significant difference in the left pre and post-ROM (t(30) = -6.93, p <0.05, 95% CI (-2.97, -6.79), d = 0.52, p < 0.05 indicated an improvement after the intervention. Average range of motion increase was 4 degrees in both legs. CONCLUSION Hamstring flexibility can be improved with a progressive 7-week Hatha yoga session and may be used as a modality to improve flexibility and function in activities of daily living as well and athletic performance.

Abstract
PURPOSE To determine the validity of wrist range of motion (ROM) measurements by the wearable-controlled ReValidate! wrist-rehabilitation game, which simultaneously acts as a digital goniometer. Furthermore, to establish the reliability of the game by contrasting ROM measurements to those found by medical experts using a universal goniometer. METHODS As the universal goniometer is considered the reference standard, inter-rater reliability between surgeons was first determined. Internal validity of the game ROM measurements was determined in a test-retest setting with healthy volunteers. The reliability of the game was tested in 34 patients with a restricted range of motion, in whom the ROM was measured by experts as well as digitally. Intraclass-correlation coefficients (ICCs) were determined and outcomes were analyzed using Bland-Altman plots. RESULTS Inter-rater reliability between experts using a universal goniometer was poor, with ICCs of 0.002, 0.160 and 0.520. Internal validity testing of the game found ICCs of - 0.693, 0.376 and 0.863, thus ranging from poor to good. Reliability testing of the game compared to medical expert measurements, found that mean differences were small for the flexion-extension arc and the radial deviation-ulnar deviation arc. CONCLUSION The ReValidate! game is a reliable home-monitoring device digitally measuring ROM in the wrist. Interestingly, the test-retest reliability of the serious game was found to be considerably higher than the inter-rater reliability of the reference standard, being healthcare professionals using a universal goniometer.

Abstract
The present study aimed to validate the Leap Motion Controller (LMC)-based Fizyosoft® HandROM System developed by our team to evaluate range of motion (ROM) for fingers, wrist, and forearm in a new clinical setting. Thirty-five healthy individuals participated in the study (all right-handed, 20-30 years old). The LMC-based Fizyosoft® HandROM System is a licensed software ROM-measurement developed by our team. Pronation/supination, wrist flexion/extension, ulnar/radial deviation and metacarpophalangeal (MCP) flexion/extension of all fingers were measured with both the Fizyosoft® HandROM System and a universal goniometer. No significant differences were found between the two measurement methods for almost all mean ROMs except for ulnar and radial deviation (p > 0.05). Highly significant correlations were found between all ROMs of the forearm, wrist, and thumb (p < 0.01). MCP flexion showed significant correlation only in the index finger (r = 0.516, p = 0.003) and little finger (r = 0.517, p = 0.004). Besides, for both measures, the intraclass correlations were good to excellent on all ROMs of the forearm, wrist, and fingers except for MCP of the middle and ring fingers (0.68-0.88). The present study results indicated that the LMC-based Fizyosoft® HandROM System could sensitively track changes in the active motion of the thumb, wrist, and forearm. It is a viable alternative for assessing ROMs of the forearm, wrist, and thumb in patient follow-up.

Abstract
BACKGROUND AND OBJECTIVE Currently, the lack of tools for physiotherapists, and the quality of these tools when physiotherapists assess patients does not allow a good diagnosis. Accurate joint range evaluation is an essential task in the daily work of physiotherapists in order to correctly assess treatment progress. In this study, we examined the reliability and safety of an Android system application called G-Pro to evaluate its characteristics and observe its usefulness as a goniometer to measure joint angles in a clinic. MATERIAL AND METHODS The standard goniometer and G-pro smartphone with the application were used to passively and bilaterally measure shoulder flexion and rotation and elbow flexion in 30 participants able to tolerate standing. RESULTS The G-pro smartphone application showed good to excellent reliability (r=0.998 to 0.896, P<.01), while the universal goniometer showed acceptable to questionable reliability (r=0.757 to 0.609) in active shoulder flexion-extension movement. CONCLUSIONS The results obtained in this study show that these devices represent an additional resource to assess joint mobility ranges. Due to technological progress, we can improve, innovate, and demonstrate the results of joint assessments to ensure their accuracy. This, in turn, ensures that the treatment provided is appropriate and specific to each patient. This tool is low cost and is accessible for health care professionals; moreover, it is easy to use since it has an incliniometer that is reliable both visually and evaluatively.

Abstract
This article describes a dataset of multiangular scattering properties of small trees (height = 0.38–0.7 m) at visible, near-infrared, and shortwave-infrared wavelengths (350–2500 nm), and provides supporting auxiliary data that comprise leaf, needle, and bark spectra, and structural characteristics of the trees. Multiangular spectra were measured for 18 trees belonging to three common European tree species: Scots pine (Pinus sylvestris L.), Norway spruce (Picea abies (L.) H. Karst), and sessile oak (Quercus petraea (Matt.) Liebl.). The measurements were performed in 47 different view angles across a hemisphere, using a laboratory goniometer and a non-imaging spectrometer. Leaf and needle spectra were measured for each tree, using a non-imaging spectrometer coupled to an integrating sphere. Bark spectra were measured for one sample tree per species. In addition, leaf and needle fresh mass, surface area of leaves, needles, and woody parts, silhouette area, and spherically averaged silhouette to total area ratio (STAR) for each tree were measured or derived from the measurements. The data are useful for modeling the shortwave reflectance characteristics of small trees and potentially forests, and thus benefit climate modeling or interpretation of remote sensing data.

Abstract
Osteoarthritis is one of the most debilitating diseases in Europe affecting the lower limb joints, especially the hip and knee, having a bad influence on gait in the long run as well. Rehabilitation physicians use gait in order for the whole body to be seen in ensemble, and through midstance as moment of gait to also take predilection to falls into consideration. Goniometry is the quantifiable measure of a rehabilitation treatment by measuring the range of motion of each treated joint and studied during time. The patients that volunteered to be part of this study have been divided into four groups, depending on the level of osteoarthritis present at the lower limb joints: hip, knee, both hip and knee osteoarthritis or control group with no osteoarthritis, have been asked to walk for a few times and the video recordings were uploaded into the Angles App where we measured the lower limb joint angles during midstance. Patients with knee osteoarthritis present a more extended hip on both dominant and non-dominant sides compared to the ones with hip osteoarthritis, hip and knee osteoarthritis or control group. The results can be explained through the body's kinematic chains that link the knee and hip, hip and pelvis during the midstance phase in the sagittal plane. A physician can use a video goniometry app in order for him to thoroughly evaluate an osteoarthritic patient as well as follow him or her during the entire course of treatment.

Abstract
The evolution of rehabilitation treatments can be quantified through goniometric measurements. Thus, a video goniometer, and an app-based goniometry program can be both useful and a reliable method of obtaining a data base through which we can see if a certain rehabilitation treatment works out for our patients and during times such as the Covid-19 pandemic, a telemedicine approach can be done. Midstance is a sub-moment of the gait pattern, important in the stability of the lower limb, but that can also direct us towards a patient prone to falls. Osteoarthritis is a disease that causes high disability because of the cellular degradation that also affects normal gait. Four groups of subjects: subjects suffering from hip osteoarthritis, knee osteoarthritis, hip and knee osteoarthritis and control group, have been filmed and recorded their midstance joint range of motion in the Angles App. The dominant limb has been proven to have a more extended ankle in the hip osteoarthritis group, compared to knee osteoarthritis, hip and knee osteoarthritis or control group. Females have presented a more extended ankle, wearing high heels for a long period of time can be the cause of that. Subjects with knee osteoarthritis have presented a more flexed ankle in the dominant limb compared to the ones suffering from hip and knee osteoarthritis or control group. The ankle joint can also have its range of motion measured with a video goniometer, helping us compare results in between sessions of rehabilitation in osteoarthritic patients.

Abstract
BACKGROUND Quadratus lumborum muscle (QL) is one of several muscles subject to tightness and relevant to symptoms in the back and hip. Although releasing the tight QL seems to resolve these symptoms in clinic, no study has investigated the effects of such releasing on the length of the hip and knee muscles. OBJECTIVE To compare muscle length of the hip and knee joints between pre- and post-releasing the QL. METHODS A quasi-experimental design (one-group pretest-posttest design) was conducted. Thirty asymptomatic participants with mean age of 20.40 years took part in the study. An examiner assessed the participants' pelvic transverse gliding movement in standing and rotation of the upper trunk in supine to perceive the end feel of tissue resistance. The side with perceived more muscle tension was selected for receiving muscle release. Before manually releasing the QL, the participant was in the modified Thomas test position and pre-test range of motion (ROM) of hip flexion, hip abduction, and knee flexion angles was measured using a standard goniometer. After releasing the QL, the aforementioned angles were measured for post-test ROM. RESULTS The hip flexion angle was significantly reduced after releasing the QL (p < 0.05), whereas no statistically significant differences were found for the other 2 angles (p > 0.05). CONCLUSION The length of iliopsoas muscle was increased after releasing the QL. The findings may be due to continuous fascial connection and similar attachment of the origins of these 2 muscles.

Abstract
Background Knowing correlations between passive goniometric and dynamic three-dimensional motion analysis measurements of lower extremity range of motion and alignment would benefit knee injury risk assessment. Purpose To investigate reliability and concurrent validity of lower extremity assessment with goniometry and three-dimensional motion analysis. Methods Thirty-eight participants (76 limbs) were examined in standardized positions by two physiotherapists with simultaneous goniometric and three-dimensional motion analysis measurements of passive range of motion and alignment. Intra-class correlation coefficient (ICC) and median differences were calculated. Results Hip rotation reliability, ICC 0.74–0.89 and validity 0.74–0.94. Tibial rotation reliability, ICC 0.24–0.75 and validity 0.08–0.61. Knee extension reliability, ICC 0.44–0.73 and validity 0.22–0.60. Knee valgus/varus reliability, ICC 0.36–0.68 and validity 0.25–0.62. Tibial torsion reliability, ICC 0.52–0.77 and validity 0.58–0.81. Ankle dorsiflexion reliability, ICC 0.12–0.73 and validity 0.51–0.83. Median differences in reliability and validity ranged from -2.0° to 3.0° and from -6.6° to 7.5° respectively. Conclusion Goniometric and three-dimensional motion analysis methods define the lower body segments differently making some degree of discrepancy in the measurements inevitable. Nevertheless, the variables chosen in this study are all strongly associated with anterior cruciate ligament rupture and some may prove useful to identify individuals at risk of knee injury during sport activities.

Abstract
BACKGROUND Headache is a common and costly health problem. Although the pathogenesis of headache is heterogeneous, reported contributing factors are dysfunctions of the upper cervical spine. The flexion rotation test (FRT) is a commonly used diagnostic test to detect upper cervical movement impairment. A digital goniometer may support precise measurement of movement impairment in the upper cervical spine. However, its reliability and validity is not assessed, yet. The aim of this study was to investigate the reliability and validity of the digital goniometer compared to an ultrasound-based movement analysis system. METHODS Two separate cross-sectional studies were conducted using the digital goniometer EasyAngle (Meloq AB, Stockholm, Sweden) for a) investigating the concurrent validity of upper cervical range of motion (ROM) during the FRT and b) determining the inter- and intra-rater reliability in the target population of patients with head and neck pain. Sixty-two participants, 39 with and 23 without head and neck pain, were recruited for the concurrent validity study. For the reliability study, a total of 50 participants were recruited. Intraclass correlation coefficients (ICC) and Bland Altmann plots were used to assess validity and ICC values, Bland Altmann plots as well as Kappa coefficients were used for estimating intra-rater and inter-rater reliability. RESULTS Concurrent validity was strong with an ICC (2,1) of 0.97 for ROM to either side (95%CI = 0.95-0.98). Bland Altman Plots revealed a mean difference between measurement systems of 0.5° for the left and 0.11° for the right side. The inter-rater ICC (2,1) was 0.66 (95%CI 0.47-0.79, p < 0.001, SEM 6.6°), indicating good reliability. The limits of agreement were between 10.25° and - 11.89°, the mean difference between both raters was - 0.82°. Intra-rater reliability for the measurement of ROM during the FRT was between 0.96 (ICC 3,1) for rater 1 and 0.94 (ICC 3,1) for rater 2. CONCLUSIONS The digital goniometer demonstrated strong concurrent validity and good to strong reliability and can be used in clinical practice to accurately determine movement impairment in the upper cervical spine.

Abstract
BACKGROUND Elbow and wrist chronic conditions are very common among musculoskeletal problems. These painful conditions affect muscle function, which ultimately leads to a decrease in the joint's Range Of Motion (ROM). Due to their portability and ease of use, goniometers are still the most widespread tool for measuring ROM. Inertial sensors are emerging as a digital, low-cost and accurate alternative. However, whereas inertial sensors are commonly used in research studies, due to the lack of information about their validity and reliability, they are not widely used in the clinical practice. The goal of this study is to assess the validity and intra-inter-rater reliability of inertial sensors for measuring active ROM of the elbow and wrist. MATERIALS AND METHODS Measures were taken simultaneously with inertial sensors (Werium™ system) and a universal goniometer. The process involved two physiotherapists ("rater A" and "rater B") and an engineer responsible for the technical issues. Twenty-nine asymptomatic subjects were assessed individually in two sessions separated by 48 h. The procedure was repeated by rater A followed by rater B with random order. Three repetitions of each active movement (elbow flexion, pronation, and supination; and wrist flexion, extension, radial deviation and ulnar deviation) were executed starting from the neutral position until the ROM end-feel; that is, until ROM reached its maximum due to be stopped by the anatomy. The coefficient of determination (r 2) and the Intraclass Correlation Coefficient (ICC) were calculated to assess the intra-rater and inter-rater reliability. The Standard Error of the Measurement and the Minimum Detectable Change and a Bland-Altman plots were also calculated. RESULTS Similar ROM values when measured with both instruments were obtained for the elbow (maximum difference of 3° for all the movements) and wrist (maximum difference of 1° for all the movements). These values were within the normal range when compared to literature studies. The concurrent validity analysis for all the movements yielded ICC values ≥0.78 for the elbow and ≥0.95 for the wrist. Concerning reliability, the ICC values denoted a high reliability of inertial sensors for all the different movements. In the case of the elbow, intra-rater and inter-rater reliability ICC values range from 0.83 to 0.96 and from 0.94 to 0.97, respectively. Intra-rater analysis of the wrist yielded ICC values between 0.81 and 0.93, while the ICC values for the inter-rater analysis range from 0.93 to 0.99. CONCLUSIONS Inertial sensors are a valid and reliable tool for measuring elbow and wrist active ROM. Particularly noteworthy is their high inter-rater reliability, often questioned in measurement tools. The lowest reliability is observed in elbow prono-supination, probably due to skin artifacts. Based on these results and their advantages, inertial sensors can be considered a valid assessment tool for wrist and elbow ROM.

Abstract
BACKGROUND Studies have shown that Q angle measurements were unreliable. Imaging studies have largely replaced the Q angle for measuring tibial tubercle lateralization. Creating a standardized protocol to measure the Q angle, with normative values, would provide a reliable reference without expensive imaging techniques. METHODS Thirty men and 27 women without history of knee problems or family history of dislocating kneecaps were subjects. Exclusion criteria were: patellofemoral abnormalities upon examination. We measured the Q angles of both knees using a standardized protocol and a long-armed goniometer. These data were analyzed to calculate normative values. RESULTS For all subjects, the mean was 14.8° (≈15°), 95% confidence interval (CI): ±5.4°. The male mean was 13.5°, 95% CI: ±5.2°. The female mean was 15.9°, 95% CI: ±4.8°. There was no significant difference between the right and left knees of the males (p = 0.52), nor of the females (p = 0.62), Beta = 0.14. The 2.4° difference between male and female means was due to the average height difference between the men and women. CONCLUSIONS This study provides a standardized Q angle measurement protocol to assess tibial tubercle lateralization at a patient's first encounter (and intra-operatively) without resorting to expensive imaging studies. These values provide a reliable reference for clinical comparison, and will allow all clinicians and sports medicine personnel to assess tubercle lateralization with reliability and validity. When using this protocol, the term "Standard Q Angle" (SQA) should be used, to avoid confusion with other measurement protocols.

Abstract
STUDY DESIGN Cross-sectional cohort. INTRODUCTION Smartphone gyroscope and goniometer applications have been shown to be a reliable way to measure wrist ROM when used by researchers or trained staff. If wrist-injured patients could reliably measure their own ROM, rehabilitation efforts could be more effectively tailored. PURPOSE OF THE STUDY To assess agreement of self-measured ROM by wrist-injured and wrist-healthy study participants using a built-in iPhone 5 level feature as compared to researcher-measured ROM using a universal goniometer (UG). METHODS Thirty wrist-healthy and 30 wrist-injured subjects self-measured wrist flexion, extension, supination, and pronation ROM using the built-in preinstalled digital level feature on an iPhone 5. Simultaneously a researcher measured ROM with a UG. RESULTS Average absolute deviation between the self-measured iPhone 5 level feature and researcher-measured UG ROM was less than 2° for all 4 movements individually and combined was found to be 1.6° for both populations. Intraclass correlation coefficient showed high correlation with values over 0.94 and Bland-Altman plots showed very strong agreement. There was no statistical difference in the ability of wrist-injured and healthy patients to self-measure wrist ROM. DISCUSSION Both populations showed very high agreement between their self-measured ROM using the built-in level feature on an iPhone 5 and the researcher-measured ROM using the UG. Both populations were able to use the iPhone self-measurement equally well and the injury status of the subject did not affect the agreement results. CONCLUSION Wrist-healthy and wrist-injured subjects were able to reliably and independently measure ROM using a smartphone level feature.

Abstract
Background Plantar fasciitis is one of the common causes of heel pain and a common musculoskeletal problem often observed by clinicians. Numerous options are available in treating plantar fasciitis conservatively, but no previous studies have compared combined conservative management protocols. Aim The aim of this study was to compare manipulation of the foot and ankle and cross friction massage of the plantar fascia; cross friction massage of the plantar fascia and gastrocsoleus complex stretching; and a combination of the aforementioned protocols in the treatment of plantar fasciitis. Setting This study was conducted at the University of Johannesburg, Chiropractic Day Clinic, and included participants that complied with relevant inclusion criteria. Methods Forty-five participants between the ages of 18 and 50 years with heel pain for more than 3 months were divided into three groups and received one of the proposed treatment interventions. The data collected were range of motion (ROM) of the ankle (using a goniometer) and pain perception using the McGill Pain Questionnaire and Functional foot index and algometer. Results The results of this study indicate that cross friction massage of the plantar fascia and stretching of the gastrocsoleus complex showed the greatest overall improvement in terms of reducing the pain and disability and ankle dorsiflexion ROM, whereas the combination group showed the greatest increase in plantar flexion. Conclusion The results demonstrated that all three protocols had a positive effect on the ROM and pain perception to patients with plantar fasciitis.

Abstract
STUDY DESIGN Clinical measurement (reliability and validity) study. INTRODUCTION Forearm supination is important in many daily activities and is thus measured by therapists and researchers usually with a universal goniometer. DrGoniometer, a SmartPhone application, has been validated for other joint angles in the body. PURPOSE OF THE STUDY To establish the reliability and validity of DrGoniometer (CDM S.r.L, Cagliari, Italy) for measuring forearm supination in healthy populations and those with forearm fractures. METHODS Participants had sustained a distal radius fracture that was treated non-surgically. Forearm supination of the participant's fractured (n = 30) and healthy forearm (n = 30) was measured using DrGoniometer and the universal goniometer by two assessors. The assessors were blinded to each other's measurements and their own previous measurements. Reliability was established by calculating Intra-class Correlation Coefficients, standard error of measurement and minimal detectable change. The validity of DrGoniometer was established against the universal goniometer using Pearson's correlation co-efficient. RESULTS Intra-rater reliability of both DrGoniometer and the universal goniometer was high for both fractured and healthy forearms (ICCs ranged from 0.74-0.88). Inter-rater reliability of both DrGoniometer and the universal goniometer was also high in the fractured forearm group (0.76 and 0.72 respectively), but low in the healthy forearm group (0.34 and 0.42 respectively). Correlation between the tools was excellent across the fractured and healthy forearm groups (0.94 and 0.93 respectively). DISCUSSION Both goniometers demonstrated good-to-excellent intrarater and iner-rater reliability except in the healthy forearm group where both goniometers demonstrated poor inter-rater reliability which could be due to assessor instructions. The speed the photo can be taken and the digital record obtained are valuable aspects of DrGoniometer. CONCLUSION DrGoniometer is a valid, alternate tool for measuring forearm supination.

Abstract
PURPOSE Information is limited regarding the validity and reliability of measurements made during remote assessment of wrist range of motion (ROM) motion. We sought to determine intra- and inter-observer agreement among visual estimation, direct goniometric measurement, and patients' self-taken digital photographs and line tracings by comparing the degree differences among measurements. We hypothesized that inter- and intra-observer differences would be less than 10° at least 90% of the time for all measurement modalities. METHODS Thirty-seven patients were enrolled in this prospective cohort study. Visual estimation immediately followed by direct goniometry of maximal active wrist ROM (extension [E], flexion [F], radial deviation, and ulnar deviation) were independently and blindly assessed by 3 different providers: a hand surgeon, a hand therapist, and an orthopedic resident. Self-taken photographs and line tracings were blindly evaluated 3 weeks later. Intra- and inter-observer agreement was described using the Bland-Altman method. RESULTS The surgeon and hand therapist observed intra-observer agreement within 10° for visual estimation of all 4 directions of motions greater than 90% of the time, but inter-observer agreement for E/F was lower (76% to 86%). Intra-observer agreement by the resident was within 10° 78% of the time for E/F. Intra-observer agreement for photographs and tracings were lower than visual estimation for all observers. Inter-observer agreement for photographs and tracings was higher than intra-observer agreement. The surgeon and hand therapist agreed within 10° at least 76% of the time, the surgeon and resident agreed within 10° at least 62% of the time, and the hand therapist and resident agreed within 10° at least 54% of the time. CONCLUSIONS Visual estimation may be a valid method of remote assessment, but compared with goniometry, measurements may be susceptible to observer bias. Self-taken photographs and line tracings are unreliable, perhaps falsely lower owing to submaximal effort from task distraction, and we question their current use for remote assessment of wrist ROM. CLINICAL RELEVANCE These results represent an initial step in evaluating potential methods of remote assessment of wrist ROM.

Abstract
BACKGROUND The orientation of the acetabular cup is a critical factor for prevention of various postoperative complications in total hip arthroplasty (THA). Although most patients are treated in either supine or lateral position during surgery, it is still unclear which position is superior to achieve more accurate cup positioning. Our study was conducted in order to answer the following questions: (1) does the supine position provide a higher accuracy of cup positioning than the lateral position in THA using modified Watson-Jones approach? (2) is there any difference in the distribution of cup position between the two positions? Hypothesis Our hypothesis was that the supine position would provide a higher accuracy of cup positioning than the lateral position in THA using modified Watson-Jones approach. PATIENTS AND METHODS A single-center prospective randomized study (registration number: UMIN000021627) was conducted between May 2016 and December 2017. We recruited a total of 60 participants undergoing unilateral primary cementless THA using modified Watson-Jones anterolateral approach based on the result of the sample size calculation. They were randomly assigned to either supine position (n=29) or lateral position (n=31). The cup alignment was targeted using a goniometer during surgery. The radiographic cup inclination was targeted to 40° and the radiographic cup anteversion was targeted considering the femoral stem anteversion during surgery. Postoperative cup alignment was measured by plain radiography and computed tomography. We defined the difference between postoperative and target cup angle as target error and our primary outcome was the absolute value of the target angle. As secondary outcome, the distribution of the target error was evaluated. The target errors of each inclination and anteversion were divided into 3 groups; neutral (-3°≤the target error≤3°), positive error (3°<the target error), and negative error (the target error<-3°). RESULTS The assessment of primary outcome for all recruited patients showed that supine group was significantly more accurate than lateral group in terms of radiographic inclination (2.4° vs. 4.5°, respectively, mean difference 2.1°; 95% confidence interval, 0.7 to 3.5; p<0.01). There was no significant difference in terms of radiographic cup anteversion (5.6° vs. 5.2°, mean difference 0.4°; 95% confidence interval, -1.8 to 2.6; p=0.69). The rate of positive error of anteversion in supine and lateral group was larger than that of negative value of anteversion (51.7% vs. 10.3% and 48.4% vs. 12.9%, respectively). Any acute complication (dislocation, fracture, and infection) was not found in both groups during postoperative 3 months. DISCUSSION In this randomized-controlled trial, higher accuracy of acetabular cup inclination was provided by supine position than by lateral position in THA. On the other hand, there was no significant difference between both groups in terms of cup anteversion. In both groups, most cups were placed with larger anteversion than we targeted. Modified Watson-Jones approach in both positions should be performed considering these results. STUDY REGISTRATION NUMBER UMIN000021627. Level of evidence II, randomised controlled study (population-limited).

Abstract
HYPOTHESIS The architecture of complex-shaped fibres affects the motion of the contact line and the evolution of its associated menisci when a fibre is immersed into a liquid. Understanding and predicting the motion of the contact line is critical in the design of complex-shaped fibres for many engineering applications as well as for surface science. While wetting on classic circular cylinders has been well studied, singularities during the wetting process of complex-shaped fibres are not yet well understood. EXPERIMENTS The dynamic wetting behaviour of axisymmetric sinus-shaped fibres immersed vertically in a liquid volume was investigated. Fibres were 3D-printed down to micrometre dimensions, and the Wilhelmy method was used in parallel with meniscus shape analysis. Moreover, a quasi-static theoretical model predicting the contact line movement and free energy of the system evolution on these fibres is also proposed. FINDINGS The observation of liquid advancing and receding fronts highlighted a stick-slip motion of the meniscus depending on both the fibre surface curvature and its intrinsic wettability. The model predicts that the behaviour of the seemingly pinned and then jumping contact line, with associated changes in apparent contact angles, can be explained by the interplay between a constant local contact angle and the movement of the bulk liquid, leading to the storage of energy which is suddenly released when the contact line passes a given point of fibre curvature. Besides, acceleration/deceleration events that take place before and after the jumps are experimentally observed in good agreement with the model.

Abstract
BACKGROUND The purpose of this study was to compare the values of quadriceps angle (Q angle) in relation to age, weight, height, gender, bilateral and postural variations, and strenuous activities on the weight bearing limbs in order to observe its variability. MATERIALS AND METHODS A total of 450 adult healthy volunteers (150 male students, 150 female students and 150 male labourers) were enrolled in this cross sectional study. Each volunteer had its height, weight and Q angles measured. Q angle was measured in all subjects bilaterally in both supine and standing position with the same goniometer. Comparison of Q angles and various parameters and groups were studied and tabulated. Correlation between age, weight, height and Q angles was determined by Karl Pearson's correlation coefficient. RESULTS Females had statistically significant higher Q angles in both knees than males of either group, and difference between males of two groups was insignificant. It was more often greater on left side (42.36%) as compared to right, both in males and females. Majority of subjects showed an increase in angle from supine to standing position. There was negative correlation between height and Q angle with both standing and supine position all three groups. Weight and age did not show significant correlation with Q angle. Physical activity did not show any significant effect on the angle. CONCLUSION Q angle is an important parameter to assess quadriceps muscle's function and its effect on knee. An increase in the angle is clearly associated with patellofemoral problems. Higher Q angle among females may predispose them to sports related injuries. It is important to take into consideration of such factors like sex, height, posture, side, foot rotation and muscle's relaxation while measuring and comparing the angle.

Abstract
BACKGROUND Smartphones have become a fundamental part of our society, not only everyday, but also professional, since many applications have emerged for the health field. The objective of the study was to analyze the reliability and concurrent validity of an app for iPhone in relation to traditional measurement. MATERIAL AND METHODS A non-experimental, double-blind validation and descriptive study. On a sample of 21 subjects, four measurements of knee mobility were performed. Two using universal goniometer (GU) and two through the application Goniometer-Pro (G-Pro) for IPhone. The X-ray was used as a reference measure of the knee flexion angle and was analyzed by a single evaluator who compared this result with that of the other evaluators. RESULTS The difference between the average intra-group values was 3.148o (± 2.669o) for GU and 2.476o (± 2.638o) for G-Pro. The inter-group mean difference reached 5.45o. The Inter-observer reliability was 0.990 for GU and 0.993 for G-Pro; as for validity, the values obtained were 0.976 for GU and 0.992 for G-Pro. CONCLUSIONS The G-Pro app is a reliable tool with a high accuracy to measure the knee flexion angle. Its results are slightly superior and more accurate to those of traditional instruments.

Abstract
BACKGROUND Comparisons across studies of generalized joint hypermobility are often difficult since there are several classification methods and methodological differences in the performance exist. The Beighton score is most commonly used and has been tested for inter- and intra-rater reliability. The Contompasis score and the Hospital del Mar criteria have not yet been evaluated for reliability. The aim of this study was to investigate the inter- and intra-rater reliability for measurements of range of motion in joints included in these three hypermobility assessment methods using a structured protocol. METHODS The study was planned in accordance with guidelines for reporting reliability studies. Healthy adults were consecutively recruited (49 for inter- and 29 for intra-rater assessments). Intra-class correlations, two-way random effects model, (ICC 2.1) with 95% confidence intervals, standard error of measurement, percentage of agreement, Cohen's Kappa (κ) and prevalence-adjusted bias-adjusted kappa were calculated for single-joint measured in degrees and for total scores. RESULTS The inter- and intra-rater reliability in total scores were ICC 2.1: 0.72-0.82 and 0.76-0.86 and for single-joint measurements in degrees 0.44-0.91 and 0.44-0.90, respectively. The difference between ratings was within 5 degrees in all but one joint. Standard error of measurement ranged from 1.0 to 6.9 degrees. The inter- and intra-rater reliability for prevalence of positive hypermobility findings the Cohen's κ for total scores were 0.54-0.78 and 0.27-0.78 and in single joints 0.21-1.00 and 0.19-1.00, respectively. The prevalence- and bias adjusted Cohen's κ, increased all but two values. CONCLUSIONS Following a structured protocol, the inter- and intra-rater reliability was good-to-excellent for total scores and in all but two single joints, measured in degrees. The inter- and intra-rater reliability for prevalence of positive hypermobility findings was fair-to-almost perfect for total scores and slight-to-almost-perfect in single joints. By using a structured protocol, we attempted to standardize the assessment of range of motion in clinical and in research settings. This standardization could be helpful in the first part of the process of standardizing the tests thus avoiding that assessment of GJH is based on chance.

Abstract
Background: A thickened coracohumeral ligament is a highly specific manifestation of, and primary restraint against external rotation in frozen shoulders. Objective: The purpose of this study was to evaluate the effects of complete arthroscopic coracohumeral ligament release on range of motion in frozen shoulder. Methods: Fifty-two consecutive shoulders in 52 patients were treated between April 2015 and June 2016. To evaluate solely glenohumeral range of motion, the scapula was fixed by an examiner with one hand (without palpating scapular motion), and range of motion was measured using a goniometer. For the first step, arthroscopic pancapsular release was performed in a beach-chair position with (Group 1) or without (Group 2) complete coracohumeral ligament release. For the final step, the remaining coracohumeral ligaments in Group 2 were released and the ranges of motion were compared to those in Group 1. Results: The average age of the patients was significantly higher in Group 1, but there were no significant differences between the two groups with respect to sex, affected side, preoperative range of motion, or American Shoulder and Elbow Society Score. Abduction, external rotation at adduction, and external and internal rotations at 90° of flexion in Group 1 were significantly greater than those in Group 2. After the additional release of the remaining coracohumeral ligaments in Group 2, all ranges of motion were significantly recovered and there was no significant difference between the groups. Conclusion: Complete coracohumeral ligament release is a recommended intraoperative procedure for regaining full range of motion in frozen shoulders.

Abstract
Opioid addiction is a world-wide tragedy, with severe consequences for both the victims and the society that must care for them. The pathways to addiction are multiple but postoperative opioid prescriptions for pain management are a major contributor to this crisis. This case report describes the differences in pain management during 2 different arthroplasties of the knees in the same person. After the first arthroplasty of the right knee 10 years ago, postoperative opioids were used, but after the second arthroplasty of the left knee in 2007, anti-inflammatory drugs took the place of opioids. The first postoperative treatment with opioids was marked by addiction and a nasty withdrawal. The recovery of knee function, driving, and return to work were prolonged. After the second arthroplasty in 2007, a combination of meloxicam (COX-2 inhibitor), high-dose acetaminophen (COX-1 inhibitor at higher doses), and diclofenac topical gel (COX-1 inhibitor with local effects) produced excellent pain control and significant reduction in swelling of the operated knee. The clinical course was smooth and recovery was rapid. The patient was walking normally and driving a car at 2 weeks and took an airplane trip at 4 weeks. After arthroplasty, postoperative opioids may not be necessary for most people.

Abstract
Background The ankle joint is a common site of musculoskeletal pathology. Measurement of its functional range of motion is a primary indicator for rehabilitation outcomes in therapy settings. The present study was designed to assess reliability and validity of a new standardised method using a D-Flex device to assess ankle range of motion. Methods A cohort of 20 healthy volunteers were recruited to measure the weight-bearing ankle range of motion using three assessment tools, namely, a goniometer, inclinometer and the D-Flex measurement devices. Repeated measures were performed both between and within observers for each device over a 48 h period. Performance evaluation of each device and their reliability was assessed using intra-class correlation coefficients and Bland and Altman plots. Results Although significant correlations (p < 0.05) were observed between devices, there were large mean differences in ankle range of motion values ranging from 4.3°-15.7°. The D-flex produced the highest inter- and intra-rater reliability (ICCs 0.76–0.95), compared to values of 0.55–0.85 and 0.32–0.71 for the goniometer and inclinometer, respectively. The Bland and Altman plots revealed a low mean observer difference for the D-Flex (mean difference = 0.7°), with the vast majority of data coincident within the 95% confidence intervals. For both the goniometer and inclinometer mean differences were higher, with values of 3.1° and 5.7° respectively. Conclusion The results of the present study provide evidence to support the use of the D-Flex system as a valid, portable, and easy to use alternative to the weight-bearing lunge test when assessing ankle dorsiflexion ROM in healthy participants.

Abstract
CONTEXT Hip rotation range of motion (ROM) is commonly assessed in individuals with lower extremity or spine pathology. It remains unknown which hip rotation ROM testing position is most reliable. OBJECTIVE To compare interrater and intrarater reliabilities between hip internal rotation (IR) and external rotation (ER) ROM in supine and seated positions. STUDY DESIGN Controlled laboratory study. SETTING University research laboratory. PARTICIPANTS A total of 19 participants (11 females and 8 males; age = 23.5 [1.2] y; height = 173.2 [8.6] cm; and mass = 69.2 [13.4] kg) without hip, knee, low back, or sacroiliac pain within the preceding 3 months or history of hip or low back surgery were recruited. INTERVENTIONS Three testers obtained measures during 2 testing sessions. Passive supine and seated hip IR and ER ROM were performed with the hip and knee flexed to 90°. MAIN OUTCOME MEASURES The primary outcome measures were hip IR and ER ROM in supine and seated positions (in degrees). Interrater and intrarater reliabilities were calculated using intraclass correlation coefficients (ICCs). Minimal detectable change was calculated. Differences between supine and seated hip IR and ER ROM values were assessed using paired t tests (significance level was .05). RESULTS Supine hip IR and ER ROM interrater and intrarater reliabilities were excellent (ICC = .75-.91). Seated hip IR ROM interrater and intrarater reliabilities were good (ICC = .64-.71). Seated hip ER ROM interrater reliability was good (ICC = .65), and intrarater reliabilities were good to excellent (ICC = .65-.82). Minimal detectable change values for supine and seated hip IR and ER ROM ranged from 6.1° to 8.6°. There were significant differences between supine and seated positions for hip IR and ER ROM (41.6° vs 44.5°; P < .01 and 53.0° vs 44.2°; P < .01, respectively). CONCLUSION Supine hip rotation had higher interrater and intrarater reliabilities. Hip IR and ER ROM values differed significantly between supine and seated positions and should not be used interchangeably.

Abstract
The need for modern patient evaluation tools continues to grow. A dependable and reproducible assessment provides objective follow-up and increases the validity of collected data. This is where mobile apps come into play, as they provide a link between surgeons and patients. They also open the possibility of interacting with other healthcare staff to exchange common scientific reference systems and databases. The CJOrtho app provides fast access to 65 classification systems in orthopedics or trauma surgery, 20 clinical outcome scores and a digital goniometer. The development of free mobile apps is an opportunity for education and better follow-up, while meeting the demands of patients.

Abstract
Hypothesis and background Accurate measurement of range of motion (ROM) is important in evaluating a pathologic shoulder and calculating shoulder scores. The aim of this study was to establish the reliability and validity of different smartphone applications (apps) in assessing pathologic shoulder ROM and to determine whether differences in recorded ROM measurements affect calculated shoulder scores. The authors hypothesized that there is no difference between shoulder ROM assessment methods and calculated shoulder scores. Methods In this nonrandomized controlled clinical trial, ROM of 75 participants with a history of shoulder disease (21 women, 54 men) was assessed using a smartphone inclinometer and virtual goniometer, a standard goniometer, and clinicians' visual estimation. Shoulder strength was assessed, and Constant-Murley (CM) and University of California–Los Angeles (UCLA) shoulder scores were calculated. Results Independent of diagnosis or operation, all cases (except for passive glenohumeral abduction of unstable shoulders) showed excellent intraclass correlation coefficients (>0.84). Interobserver reliability was excellent for all ROM measures (intraclass correlation coefficient > 0.97). All modalities had excellent agreement to values attained with the universal goniometer. There were no differences for the calculated CM or UCLA scores between the modalities employed to measure ROM. Conclusions A smartphone inclinometer or virtual goniometer is comparable to other clinical methods of measuring pathologic shoulder ROM. Clinicians can employ smartphone applications with confidence to measure shoulder ROM and to calculate UCLA and CM scores. The apps are also available to patients and may be a useful adjunct to physiotherapy, especially in cases of limited access to health care services.

Abstract
BACKGROUND There are easily accessible tools on smartphones (APP) for measuring elbow range of motion (ROM). The purpose of this study is to evaluate the validity of a particular APP in determining elbow ROM in comparison with the commonly used goniometer (GON), surgeon estimation of range (EST) and measurement on X-ray (XR). METHODS The study included 20 patients (40 elbows). Flexion, extension, pronation and supination were measured using three different methods: EST, GON and APP. Radiographic measurements were taken using the average humeral diaphysis axis and dorsal midthird of ulna in flexion and extension. RESULTS The accuracy of the three different methods has been compared to GON using statistical analysis (ANOVA and paired samples test). There was no statistically significant difference for XR flexion measurement (mean of 2.8° ± 1.5°). The APP overestimated flexion (mean of 6.4° ± 1.0°), and EST underestimated it (mean of - 7.9° ± 1.1°). For extension, the mean difference was 2.8° ± 0.7° for EST and - 26.8° ± 3.1° for XR. The APP method did not significantly differ from GON. Supination accuracy was greater with EST (2.7° ± 1.7°) than with APP (5.9° ± 1.9°). There was no difference for pronation measurement with both EST and APP. CONCLUSIONS This study is the first comparing four measurement techniques of elbow ROM. Our results showed that EST was only accurate for forearm rotation. The XR scored the best for flexion but is less reliable for extension. Surprisingly, compared to GON, APP did not correlate as we expected for flexion and supination, but the other methods were also inaccurate. We found APP to be very useful to measure complete arc of motion (difference between maximal flexion and maximal extension).

Abstract
BACKGROUND Although the clinical assessment of ankle dorsiflexion has traditionally been measured utilising various goniometric means, the validity of this static examination has never been investigated. Since any impairment in ankle flexibility is likely to result in injuries, it is imperative that the correct examination technique is conducted. HYPOTHESIS/PURPOSE To determine whether a clinical diagnosis of ankle equinus, or limited ankle dorsiflexion, correlates with a decreased dorsiflexion range of movement of the foot and ankle during gait. METHODS Twenty participants with a clinical diagnosis of ankle equinus underwent optoelectronic motion capture utilising the Rizzoli foot model. Participants were divided into two groups, Group A with <-5° of dorsiflexion and Group B with -5° to 0° of ankle dorsiflexion. RESULTS Participants in Group B had a mean dynamic ankle dorsiflexion angle of 13.9°, while those in Group A had a mean dorsiflexion angle of 4.4°, resulting in a significant difference (p=0.004) between the two groups. Likewise, foot mean dynamic dorsiflexion angle of Group B was 17.13° and Group A 8.6° (p=0.006). CONCLUSION There is no relationship between a static diagnosis of ankle dorsiflexion at 0° with dorsiflexion during gait. On the other hand, those subjects with less than -5° of dorsiflexion during static examination did exhibit reduced ankle range of motion during gait.

Abstract
Background New reliable devices for range of motion (ROM) measures in older adults are necessary to improve knowledge about the functional capability in this population. Dorsiflexion ROM limitation is associated with ankle injuries, foot pain, lower limb disorders, loss of balance, gait control disorders and fall risk in older adults. The aim of the present study was to assess the validity and reliability of the Leg Motion device for measuring ankle dorsiflexion ROM in older adults. Methods Adescriptive repeated-measures study was designed to test the reliability of Leg Motion in thirty-three healthy elderly patients older than 65 years. The subjects had to meet the following inclusion and exclusion criteria in their medical records: older than 65 years; no lower extremity injury for at least one year prior to evaluation (meniscopathy, or fractures) and any chronic injuries (e.g., osteoarthritis); no previous hip, knee or ankle surgery; no neuropathic alterations and no cognitive conditions (e.g., Alzheimer’s disease or dementia). Participants were recruited through the person responsible for the physiotherapist area from a nursing center. The subjects were evaluated in two different sessions at the same time of day, and there was a break of two weeks between sessions. To test the validity of the Leg Motion system, the participants were measured in a weight-bearing lunge position using a classic goniometer with 1° increments, a smartphone with an inclinometer standard app (iPhone 5S®) with 1° increments and a measuring tape that could measure 0.1 cm. All testing was performed while the patients were barefoot. The researcher had ten years of experience as a physiotherapist using goniometer, tape measure and inclinometer devices. Results Mean values and standard deviations were as follows: Leg Motion (right 5.15 ± 3.08; left 5.19 ± 2.98), tape measure (right 5.12 ± 3.08; left 5.12 ± 2.80), goniometer (right 45.87° ± 4.98; left 44.50° ± 5.54) and inclinometer app (right 46.53° ± 4.79; left 45.27° ± 5.19). The paired t-test showed no significant differences between the limbs or between the test and re-test values. The test re-test reliability results for Leg Motion were as follows: the standard error of the measurement ranged from 0.29 to 0.43 cm, the minimal detectable difference ranged from 0.79 to 1.19 cm, and the intraclass correlation coefficients (ICC) values ranged from 0.97 to 0.98. Conclusions The results of the present study indicated that the Leg Motion device is a valid, reliable, accessible and portable tool as an alternative to the classic weight-bearing lunge test for measuring ankle dorsiflexion ROM in older adults.

Abstract
BACKGROUND Goniometers are commonly used to measure range of motion in the musculoskeletal system. Recently smartphone goniometry applications have become available to clinicians. OBJECTIVE Compare angular measures using a universal goniometer and a smartphone application. METHODS Thirty four healthy women with at least 20° of limited range of motion regarding knee extension were recruited. Knee flexion angles of the dominant limb were measured with a universal goniometer and the ROM© goniometric application for the smartphone. Three trained examiners compared the two assessment tools. RESULTS Strong correlations were found between the measures of the universal goniometer and smartphone application (Pearson's correlation and interclass correlation coefficient > 0.93). The measurements with both devices demonstrated low dispersion and little variation. CONCLUSION Measurements obtained using the smartphone goniometric application analyzed are as reliable as those of a universal goniometer. This application is therefore a useful tool for the evaluation of knee range of motion.

Abstract
A low-cost single-crystal NMR kit is presented along with a web-based post-processing software. The kit consists of a piezo-crystal motor and a goniometer for the crystal, both embedded in a standard wide-bore NMR probe with a 3D printed scaffold. The NMR pulse program controls the angle setting automatically, and the post-processing software incorporates a range of orientation-angle discrepancies present in the kit and other single-crystal setups. Results with a NaNO3 single-crystal show a high degree of reproducibility and excellent agreement with previous findings for the anisotropic quadrupolar interaction.

Abstract
PURPOSE To compare goniometric and visual assessments of angular hand joint and wrist joint positions measured by board-certified hand surgeons and certified hand therapists. We hypothesized that visual estimation would be similar to the goniometric measurement accuracy of digital and wrist joint positions. METHODS The wrist, index finger metacarpophalangeal (MCP) joint, and index finger proximal interphalangeal (PIP) joint were evaluated in different positions by 40 observers: 20 board-certified hand surgeons and 20 certified hand therapists. Each observer estimated the position of the wrist, index MCP joint, and index PIP joint of the same volunteer, who was positioned in low-profile orthoses to reproduce predetermined positions. Following visual estimation, the participants measured the same joint positions using a goniometer. The control measurement was digitally determined by a radiologist who obtained radiographs of the hand and wrist positions in each orthosis. Observers were blinded to the results of control measurements. RESULTS When considering all joints at all positions, neither visual assessments nor goniometer assessments were consistently within ± 5° of the measurements obtained on control radiographs. When considering individual joints, goniometer measurements were significantly closer to control radiograph measurements than the visual assessments for all 3 PIP joint positions. There was no difference for the measurements at the wrist or for 2 of the 3 MCP joint positions. Significant differences between surgeon and therapist joint angle measurements were not observed when comparing visual and goniometer assessments to radiograph controls. CONCLUSIONS Compared with radiograph measurements, neither visual nor goniometer assessment displayed high levels of accuracy. On average, visual assessment of the angular positions of the index MCP and wrist joint were as accurate as the goniometer assessment, whereas goniometer assessment of the angular position of the PIP joint was more accurate than visual assessment. There was a relatively high degree of between-observer variability in measurements, and therefore, no one person's measurements could be consistently relied upon to be accurate. TYPE OF STUDY/LEVEL OF EVIDENCE Diagnostic II.

Abstract
BACKGROUND CONTEXT Lumbar pathology is often associated with axial pain or neurologic complaints. It is often presumed that such pain is associated with decreased lumbar motion; however, this correlation is not well established. The utility of various outcome measures that are used in both research and clinical practice have been studied, but the connection with range of motion (ROM) has not been well documented. PURPOSE The current study was performed to assess objectively the postulated correlation of lumbar complaints (based on standardized outcome measures) with extremes of lumbar ROM and functional ROM (fROM) with activities of daily living (ADLs) as assessed with an electrogoniometer. STUDY DESIGN/SETTING This study was a clinical cohort study. PATIENT SAMPLE Subjects slated to undergo a lumbar intervention (injection, decompression, and/or fusion) were enrolled voluntarily in the study. OUTCOME MEASURES The two outcome measures used in the study were the Visual Analogue Scale (VAS) for axial extremity, lower extremity, and combined axial and lower extremity, as well as the Oswestry Disability Index (ODI). METHODS Pain and disability scores were assessed with the VAS score and ODI. A previously validated electrogoniometer was used to measure ROM (extremes of motion in three planes) and fROM (functional motion during 15 simulated activities of daily living). Pain and disability scores were analyzed for statistically significant association with the motion assessments using linear regression analyses. RESULTS Twenty-eight men and 39 women were enrolled, with an average age of 55.6 years (range, 18-79 years). The ODI and VAS were associated positively (p<.001). Combined axial and lower extremity VAS scores were associated with lateral and rotational ROM (p<.05), but not with flexion/extension or any fROM. Similar findings were noted for separately analyzed axial and lower extremity VAS scores. On the other hand, the ODI correlated inversely with ROM in all planes, and fROM in at least one plane for 10 of 15 ADLs (p<.05). CONCLUSIONS Extremes of lumbar motion and motions associated with ADLs are of increasing clinical interest. Although the ODI and VAS are associated with each other, the ODI appears to be a better predictor of these motion parameters than the VAS (axial extremity, lower extremity, or combined) and may be more useful in the clinical setting when considering functional movement parameters.

Abstract
For diagnostic and therapeutic purposes, the joint angle measurement of a patient after an accident or a surgical operation is significant for monitoring and evaluating the recovering process. This paper proposed an optical fiber sensor for the measurement of angular displacement. The effect of beveled fiber angle on the detected light signal was investigated to find an appropriate mathematical model. Beveled fiber tips redirected the light over a range of angles away from the fiber axis. Inverse polynomial models were applied to directly obtain and display the joint angle change in real time with the Lab-VIEW program. The actual joint angle correlated well with the calculated LabVIEW output angle over the test range. The proposed optical sensor is simple, cost effective, small in size, and can evaluate the joint angle in real time. This method is expected to be useful in the field of rehabilitation and sport science.

Abstract
Objectives The development of tibiofemoral angle in children has shown ethnic
variations. However this data is unavailable for our population. Methods We measured the tibiofemoral angle (TFA) and intercondylar and
intermalleolar distances in 360 children aged between two and 18
years, dividing them into six interrupted age group intervals: two
to three years; five to six years; eight to nine years; 11 to 12
years; 14 to 15 years; and 17 to 18 years. Each age group comprised
30 boys and 30 girls. Other variables recorded included standing
height, sitting height, weight, thigh length, leg length and length
of the lower limb. Results Children aged two to three years had a valgus angulation with
a mean TFA of 1.8° (sd 0.65) in boys and 2.45° (sd 0.87)
in girls. Peak valgus was seen in the five- to six-year age group,
with mean TFAs of 6.7° (sd 1.3) and 7.25° (sd 0.64)
for boys and girls, respectively. From this age the values gradually
declined to a mean of 3.18° (sd 1.74) and 4.43° (sd 0.68)
for boys and girls, respectively, at 17 to 18 years. Girls showed
a higher valgus angulation than boys at all age groups. Conclusion This study defines the normal range of the TFA in south Indian
boys and girls using an easy and reliable technique of measurement
with a standardised custom-made goniometer. Cite this article: Bone Joint Res 2013;2:155–61.

Abstract
BACKGROUND The quality of cardiopulmonary resuscitation (CPR) during ambulance transportation is suboptimal, and therefore measures that can improve the quality are desirable. PURPOSE To evaluate whether the use of a stabilization device can improve the quality of CPR during ambulance transportation. METHODS This randomized controlled crossover trial enrolled 22 experienced ambulance officers. Each participant performed CPR in an ambulance under three conditions with 72 h apart, each condition for 10 min: non-moving (NM), moving without device (MND), and moving with device (MD). The sequences of conditions were randomized. The primary outcomes were effective chest compressions recorded by the Laerdal Resusci-Anne Skill-reporter manikin. The secondary outcomes included the severity of back pain scored using the Brief Pain Inventory short-form, the physiology parameter before and after CPR, and the changes in postural stability which was represented by the sway index (SI) of lower back measured using a goniometer. RESULTS The overall effective compressions in 10 min were 87.0±17% for NM, 59.0±19% for MND, and 69.0±23% for MD (p<0.001). Compared to MND, MD had a lower no-flow fraction while driving on curved sections (0.04 vs. 0.29, p<0.001). Whereas the pain severity and social interference scores were similar under all conditions, MND had a higher SI than MD and NM. CONCLUSIONS The use of a stabilization device can improve the quality of CPR and posture stability during ambulance transportation, although the effects on the severity of back pain were not significant.

Abstract
The potential for directional optical and thermal imagery is very large. Field measurements have been performed with a goniometer on which thermal instruments were attached. In order to reduce dynamical effects the goniometer was adjusted to run in automated mode, for zenith and azimuthal direction. Directional measurements were performed over various crops with increasing heterogeneity. The improvements to the goniometer proved successful. For all the crops, except the vineyard, the acquisition of the directional thermal brightness temperatures of the crops went successfully. The large scale heterogeneity of the vineyard proved to be larger then the goniometer was capable of. The potential of directional thermal brightness temperatures has been proven.
