Reliability and Concurrent Validity of Smartphone Clinometer Application for Measuring Scapular Rotations in Subjects With and Without Shoulder Pain.

CONTEXT:   Clinical assessment of scapular motion is obscured by a lack of clinically accessible and feasible angular measurement tools. This study evaluates the reliability and validity of the smartphone "Clinometer" app in measuring scapular upward rotation (UR) and anteroposterior tilt. DESIGN: Psychometric analysis. METHODS: We recruited 57 participants-10 with and 47 without shoulder pain. Two physical therapists consecutively measured both scapular movements using the Clinometer app at the arm by the side (rest), 30°, 60°, 90°, and 120° of humeral elevation in the scapular plane; one therapist measured again after 2 days. For evaluating concurrent validity, we compared the Clinometer scores with those measured using an electromagnetic motion capture system in 10 healthy participants. Intraclass correlation coefficients (ICC) with standard error of measurement (SEM) and minimal detectable difference at 90% confidence intervals (MDD90) were calculated. Concurrent validity was evaluated using repeated-measures analysis of variance followed by post hoc testing with Tukey-Kramer test (P < .05). RESULTS: We observed good intrarater reliability (ICC: UR = .76-.85, tilt = .69-.9; SEM: 2.2°-3.5°; MDD90: ∼5°-8°) and moderate to good interrater reliability (ICC: UR = .66-.78, tilt = .66-.76; SEM: 3.6°-8°; MDD90: ∼9°-18°) for both rotations. The Clinometer scores for UR were comparable to electromagnetic motion capture system at all angles except 90° (difference ∼8°); for scapular tilt, the scores were comparable only at rest and 30° elevation. CONCLUSION: The Clinometer app is reliable and valid for measuring scapular UR throughout and for scapular tilt at lower humeral elevation angles. The MDD90 values for scapular rotations computed in this study can be helpful in rehabilitation planning and future research.

Role of interventions targeting plantar cutaneous receptors in improving postural control in chronic ankle instability: A systematic review with meta-analysis.

INTRODUCTION: Chronic ankle instability (CAI) is a disorder that occurs after one or more acute ankle sprains and is characterised by persistent symptoms which include episodes of ''giving way'' a sensation of instability, recurrent ankle sprains, and functional deficits. Despite of effective treatment strategies a comprehensive approach is needed that can break this continuum of disability and improve the postural control. A systematic review with meta-analysis assessing the effectiveness of interventions targeting plantar cutaneous receptors for improving postural control in individuals with chronic ankle instability. METHODS: The systematic review with meta-analysis was performed following PRISMA guidelines. Outcome measure used to evaluate the improvement in which static postural control was assessed on SLBT (Single limb balance test) and COP (Centre of pressure) whereas dynamic postural control was assessed on SEBT (star excursion balance test) and scores expressed as mean ± SD and random-effects model were performed, and heterogeneity between the studies was calculated using the I2 statistic. RESULTS: A total of 168 CAI populations were included among the 8 selected studies in the meta-analysis. In which,5 studies using Plantar massage and 3 studies using foot insole were assessed, with moderate to high quality on the Pedro scale (range 4-7). For single and six-sessions of plantar massage showed insignificant effect on SLBT COP and for the single session of custom moulded FO showed insignificant effect on SEBT. CONCLUSION: The meta-analysis showed non-significant pooled results for plantar massage and foot orthotics on static and dynamic postural control when assessed on postural outcome measures. Further high-quality evidence-based trials would be required to highlight the importance of sensory targeted approaches to treat the postural instability in CAI patients.

Influence of Tensioner's Mobilization on the Centralization of Symptoms in Cervicobrachial Pain Syndrome: A Randomized Controlled Trial.

STUDY DESIGN: This study was designed as a randomized controlled trial. PURPOSE: The present study aimed to determine the impact of neural mobilization by tensioner's technique (NMTT) on the centralization of symptoms and pain in patients with cervicobrachial pain syndrome (CBPS). OVERVIEW OF LITERATURE: CBPS is a disabling condition of the neck that is characterized by pain and paresthesia in the upper quarter. Several techniques have successfully provided immediate and long-term relief in CBPS; however, few studies have evaluated the effect of these techniques on the centralization of symptoms. METHODS: Thirty patients aged 18-45 years with a complaint of pain in the neck that had persisted for 2-12 weeks radiating to the arm and fulfilling Elvey's criteria were randomly selected and divided into two groups. Group A received NMTT plus conventional treatment (hot pack and postural advice with cervical lateral glide), and group B received only conventional treatment 3 times a week for 2 weeks. The outcome measures were Wernicke's scale score for the centralization of symptoms and Visual Analog Scale score for pain intensity. Within- and between-group comparisons were made before initiating treatment and at the end of the 3rd and 6th sessions. Within group analyses for the centralization values were performed using Friedmann test, and between-group analyses were performed using Mann-Whitney test. A 2×3 mixed model of the analysis of variance was used for analyzing the pain levels. RESULTS: There was a significant difference (p<0.05) within and between the groups for both the measures at the end of the 3rd and 6th sessions. Thus, NMTT may be beneficial in decreasing the peripheralization of symptoms and pain intensity in patients with CBPS. CONCLUSIONS: NMTT can be used as an alternative and effective treatment option for patients with CBPS.

Errors in Measuring Glenohumeral Arthrokinematics With 2-Dimensional Fluoroscopy.

Two-dimensional fluoroscopic imaging allows measurement of small magnitude humeral head translations that are prone to errors due to optical distortion, out-of-plane imaging, repeated manual identification of landmarks, and magnification. This article presents results from in vivo and in vitro fluoroscopy-based experiments that measure the errors and variability in estimating the humeral head translated position in true scapular plane and axillary views. The errors were expressed as bias and accuracy. The variability with repeated digitization was calculated using the intraclass correlation coefficient (ICC) and the standard error of measurement. Optical distortion caused underestimation of linear distances. The accuracy was 0.11 and 0.43 mm for in vitro and in vivo experiments, respectively, for optical distortion. The intrarater reliability was excellent for both views (ICC = .94 and .93), and interrater reliability was excellent (ICC = .95) for true scapular view but moderate (ICC = .74) for axillary views. The standard error of measurement ranged from 0.27 to 0.58 mm. The accuracy for the humeral head position in 10° out of true scapular plane images ranged from 0.80 to 0.87 mm. The current study quantifies the magnitude of error. The results suggest that suitable measures could be incorporated to minimize errors and variability for the measurement of glenohumeral parameters.

Primary cutaneous large B-cell lymphoma of scalp: Case report of a rare variant.

Primary cutaneous large B-cell lymphoma (Bcl) is defined as a lymphoma composed of large cells constituting more than 80% of the infiltrate and absence of extracutaneous involvement after staging investigations. In the new World Health Organization/European Organization for Research and Treatment of Cancer classification, cutaneous Bcls with large cells are of three types - primary cutaneous large Bcl leg type (PCLBCLLT), primary cutaneous follicle center lymphoma diffuse type (PCFCLDT), and primary cutaneous large Bcls other (PCLBCLO). These three different types are distinct in terms of their clinicopathological features and survival. The PCLBCLO has intermediate features between those of PCLBCLLT and PCFCLDT. We present a case of PCLBCLO in a 57-year-old male who presented with a scalp swelling. Ultrasonography examination was suggestive of a sebaceous cyst. Computed tomography scan revealed the presence of an ill-defined hyperdense region in the soft tissue of the scalp region extending into the deeper layers of the scalp. Fine-needle aspiration cytology (FNAC) revealed the presence of atypical lymphoid cells. Diagnosis was confirmed by biopsy and immunohistochemistry. Patient received rituximab combined with doxorubicin, vincristine, cyclophosphamide, and prednisolone regimen with complete resolution of the lesion. We present this case for its rarity, the utility of FNAC in early diagnosis, and to discuss the differential diagnosis.

The use of evidence-based practices for the management of shoulder impingement syndrome among Indian physical therapists: a cross-sectional survey.

BACKGROUND: The understanding of the pathomechanics of shoulder impingement has evolved over the years. Likewise, assessment techniques and effective treatment strategies have also been developed. Physical therapists should keep up-to-date on the current evidence. OBJECTIVE: This study explored the practices currently used by Indian physical therapists for the assessment and management of shoulder impingement syndrome (SIS). METHOD: Using an online questionnaire, therapists were asked to declare the causes, methods of assessment and their choices of physical therapy techniques for the management of SIS. The proportions of therapists using different techniques were analyzed descriptively, and comparisons across gender, experience level, and training were made. Data were analyzed to see if the choices of respondents compared with their responses for etiology. RESULTS: A total of 211 responses were analyzed. Most respondents (>75%) believed that overuse and abnormal motion/posture are the most significant causes of SIS. However, fewer respondents reported assessing posture (60.2%) and dyskinesis, especially in women (24.2%). Ninety-four percent of the respondents reported using exercises, but exercise prescription was rather generic. Therapists additionally trained in the techniques of joint mobilization or taping declared using these techniques more frequently. The use of interferential therapy and ultrasound was reported by 89.5% and 98.4% of respondents, respectively CONCLUSION: Most therapists declared awareness of current recommended practices, but patient assessment, exercise prescription, and use of electrotherapy modalities were only partially based on current evidence. The study helps to identify gaps in current physical therapy approaches to SIS in India.

Pemphigoid Vegetans in Childhood: A Case Report and Short Review of Literature.

Pemphigoid vegetans is a very rare type of bullous pemphigoid which usually affects the elderly and has not been reported in children. It shows a clinical resemblance to pemphigus vegetans but has distinct histological and immunopathological features of bullous pemphigoid. A 9-year-old girl presented with recurrent purulent and verrucous vegetating lesions on her forehead, groin and vulva along with scaling, crusted, bullous and purulent lesions on the eyelids, periorbital, periauricular, perioral region and lips. She had oral lesions and a cerebriform tongue. Though she showed clinical features of pemphigus vegetans, histology revealed a subepidermal blister with the absence of acantholysis. Direct immunofluorescence studies were suggestive of bullous pemphigoid. On clinicopathological correlation, a diagnosis of pemphigoid vegetans was made. She responded well to oral corticosteroids and dapsone therapy with complete resolution of the lesions.
