“…The cervical flexion angle was measured by a new iPhone application (Goniometer Pro) (Figure 1). Pourahmadi et al measured cervical flexion angles using Goniometer Pro and reported good reliability: ICC > 0.65, SEM < 3.11°, and MDC < 8.62° [21]. In our study, 10 subjects were recruited to calculate Goniometer Pro reliability during 50° of cervical flexion: ICC > 0.71, SEM < 0.61°, and MDC < 1.96°.…”

Background. Neck and shoulder complaints caused by poor posture may influence upper trapezius stiffness. The relationship between the shear elastic modulus of the upper trapezius and cervical flexion angles is unknown. Therefore, it is essential to assess upper trapezius stiffness during cervical flexion. The objectives of this study were to (1) determine the intra- and interoperator reliabilities of evaluating upper trapezius stiffness and calculate the minimal detectable change (MDC); (2) examine the elastic modulus alterations of the upper trapezius during cervical flexion; and (3) explore the difference of upper trapezius stiffness between the dominant and nondominant sides. Methods. Twenty healthy male participants were recruited in this study. The shear modulus of the upper trapezius was evaluated by two independent investigators using shear wave elastography (SWE) during cervical flexion at 0° and 50°. Findings. The intraoperator (intraclass correlation coefficient ICC=0.85–0.86) and interoperator (ICC=0.94–0.98) reliabilities for measuring the shear elastic modulus of the upper trapezius during the cervical flexion ranged from good to excellent. An increase of 35.58% in upper trapezius stiffness was found at 0° to 50° of cervical flexion, and the MDC was 7.04 kPa. In addition, a significant difference was obtained in the elastic modulus of the upper trapezius muscle between the dominant and nondominant sides (P<0.05). Conclusions. Our findings revealed that SWE could quantify the elastic modulus of the upper trapezius and monitor its changes. Therefore, further studies are required to delineate the modulation in upper trapezius muscle stiffness among subjects with neck and shoulder pain.

“…Twenty-three of 25 studies demonstrated excellent inter-rater reliability as defined by an ICC > 0.75 for more than 50% of the joint movements they examined, with only two studies not satisfying this threshold for relative inter-rater reliability [37, 45]. Six out of 11 studies reported good absolute inter-rater reliability as defined by a SEM or MDC < 5 o or LOA < ± 9.8 o for more than 50% of the joint movements they examined, with five studies not satisfying this criteria [27, 30, 31, 39, 42]. While Pourahmadi et al [30] was deemed to not meet this threshold of absolute inter-rater reliability, this was based on all four MDC values > 5 o , although the SEM values for the same movements were all < 5 o .…”

Reliability and validity of clinically accessible smartphone applications to measure joint range of motion: A systematic review

et al. 2019

Measuring joint range of motion is an important skill for many allied health professionals. While the Universal Goniometer is the most commonly utilised clinical tool for measuring joint range of motion, the evolution of smartphone technology and applications (apps) provides the clinician with more measurement options. However, the reliability and validity of these smartphones and apps is still somewhat uncertain. The aim of this study was to systematically review the literature regarding the intra- and inter-rater reliability and validity of smartphones and apps to measure joint range of motion. Eligible studies were published in English peer-reviewed journals with full text available, involving the assessment of reliability and/or validity of a non-videographic smartphone app to measure joint range of motion in participants >18 years old. An electronic search using PubMed, Medline via Ovid, EMBASE, CINAHL, and SPORTSDiscus was performed. The risk of bias was assessed using a standardised appraisal tool. Twenty-three of the eligible 25 studies exceeded the minimum 60% score to be classified as a low risk of bias, although 3 of the 13 criteria were not achieved in >50% of the studies. Most of the studies demonstrated adequate intra-rater or inter-rater reliability and/or validity for >50% of the range of motion tests across all joints assessed. However, this level of evidence appeared weaker for absolute (e.g. mean difference ± limit of agreement, minimal detectable change) than relative (e.g. intraclass correlation, correlation) measures; and for spinal rotation than spinal extension, flexion and lateral flexion. Our results provide clinicians with sufficient evidence to support the use of smartphones and apps in place of goniometers to measure joint motion. Future research should address some methodological limitations of the literature, especially including the inclusion of absolute and not just relative reliability and validity statistics.

“…Objective methods that can be used for measuring AHP, including using a cervical range of motion device [ 71 ], orthopaedic goniometer [ 72 ], torticollometer, Harms’ wall [ 73 , 74 ] and other devices. More recently developed smartphone applications may also have a role in the evaluation of AHP [ 75 ] but are not in routine use currently.…”

Nystagmus is an eye movement disorder characterised by abnormal, involuntary rhythmic oscillations of one or both eyes, initiated by a slow phase. It is not uncommon in the UK and regularly seen in paediatric ophthalmology and adult general/strabismus clinics. In some cases, it occurs in isolation, and in others, it occurs as part of a multisystem disorder, severe visual impairment or neurological disorder. Similarly, in some cases, visual acuity can be normal and in others can be severely degraded. Furthermore, the impact on vision goes well beyond static acuity alone, is rarely measured and may vary on a minute-to-minute, day-to-day or month-to-month basis. For these reasons, management of children with nystagmus in the UK is varied, and patients report hugely different experiences and investigations. In this review, we hope to shine a light on the current management of children with nystagmus across five specialist centres in the UK in order to present, for the first time, a consensus on investigation and clinical management.
