measurement of the knee flexion angle with a Smartphone Application is precise and accurate
Journal of Arthroplasty, 2013Co-Authors: Jeanyves JennyAbstract:We hypothesized that the measurement of the knee flexion angle measured with a specific Smartphone Application was different from the reference measurement with a navigation system designed for total knee arthroplasty (TKA). Ten consecutive patients operated on for navigation assisted TKA were selected. Six navigated and 6 Smartphone measurements of knee flexion angle were obtained for each patient. The paired difference between measurements and their correlation were analyzed. The mean paired difference between navigated and Smartphone measurements was -1.1° ± 6.8° (n.s.). There was a significant correlation between both measurements. The coherence between both measurements was good. The intra-observer and inter-observer reproducibility were good. The Smartphone Application used may be considered as precise and accurate. The accuracy may be higher than other conventional measurement techniques.

Measurement of the Knee Flexion Angle With a Smartphone: Application Is Precise and Accurate
Journal of Bone and Joint Surgery-british Volume, 2013Co-Authors: Jeanyves JennyAbstract:INTRODUCTION The magnitude of knee flexion angle is a relevant information during clinical examination of the knee, and this item is a significant part of every knee scoring system. It is generally performed by visual analysis or with manual goniometers, but these techniques may be neither precise nor accurate. More sophisticated techniques are only possible in experimental studies. Smartphone technology might offer a new way to perform this measurement with increased accuracy. MATERIAL 20 patients operated on for unicompartmental or total knee replacement with help of a navigation system participated to the study. There were 13 women and 7 men with a mean age of 72.1 years. METHODS All patients were operated on for unicompartmental or total knee replacement. All patients were operated on with help of a non-image based navigation system. The navigation system is able to measure very accurately the knee flexion angle. The Smartphone Application allows measuring this angle in two steps 1) recording the reference position by putting the Smartphone on the operating table, 2) recording the knee flexion angle by putting the Smartphone against the tibial crest. Two observers participated to the study. The first observer performed three independent navigated measurements followed by three independent Smartphone measurements while positioning the knee under visual control in full extension, at 0°, 30°, 60°, 90° of knee flexion and at maximal flexion; the second observer performed only one set of measurements. The intra- and inter-observer variability was assessed by calculation of the intra-class correlation coefficient. Navigated and Smartphone data were compared by a paired Wilcoxon test and calculation of the Spearman coefficient of correlation at a 5% level of significance. RESULTS There was no significant difference between paired navigated and Smartphone measurements at any degree of knee flexion. There was a strong correlation between the two data sets. The intra- and inter-observer reproducibility was high. DISCUSSION-CONCLUSION There was a high agreement between the navigated measurements considered as the reference and the Smartphone measurements. This new technology is easy to use and extensively available. It allows improving significantly the precision and the accuracy of the measurement of the knee flexion angle without technical difficulties. This technique might allow a self-control by the patient of the progression of the post-operative rehabilitation. SUMMARY The Smartphone Application allows improving significantly the precision and the accuracy of the measurement of the knee flexion angle without technical difficulties.

Journal of Hypertension, 2016Co-Authors: J L Reciorodriguez, Cristina Agudoconde, C Castanosanchez, C Martinmartin, P Martinezperez, C Monterosanchez, Rosario Alonsodominguez, Natalia Sanchezaguadero, Carlos Martincantera, Natividad GonzalezviejoAbstract:Objective: The aims of this study are to develop and validate a Smartphone Application, and to evaluate the effect of adding this tool to a standardized intervention designed to improve adherence to the Mediterranean diet and to physical activity. In this abstract, we show the baseline data and the evaluation its comparability in both groups. Design and method: A randomized, double-blind, multicenter, parallel group clinical trial was carried out. A total of 833 subjects were included (415 in intervention group and 418 in control group). Counseling common to both groups (control (CG) and intervention (IG)) was provided on adaptation to the Mediterranean diet and on physical activity. The intervention group moreover received a training on the use of a Smartphone Application designed to promote a healthy diet and increased physical activity for three months. The main endpoints were the changes in physical activity, assessed by accelerometer and the 7 day Physical Activity Recall interview, and adaptation to the Mediterranean diet. Results: The mean age was 51.4 in IG and 52.3 in CG; women was 64 and 60% respectively with no difference between groups. No differences were found in marital status, educational level and employment status. We also found no difference in clinical (body mass index, waist circumference and blood pressure) biochemical (glucose and lipids) and hemodynamic variables analyzed. The mean dose of physical activity was 865.8 METS / minute/week in CG and 864.6 in IG, being active (> 450 METS / min / week) 48.6 and 49.2 respectively (p > 0.05). The count / minute by accelerometer were 65.9 in CG and 64.4 in IG (p > 0.05). The mean number of criteria compliments of Mediterranean diet was 7.2 and 7.4 and the percent subject with correct compliment (> = 9) were 28% in CG and 34% in IG respectively (p > 0.05). Conclusions: The comparability of both groups at baseline is appropriate, since it is not found significant differences in either the main variables or other demographic, clinical and laboratory parameters that could be confounding.

Behavioural activation versus mindfulness-based guided self-help treatment administered through a Smartphone Application: a randomised controlled trial.
BMJ Open, 2014Co-Authors: Anna Trüschel, Linnea Jarl, Susanna Magnusson, Tove Windahl, Robert Johansson, Per Carlbring, Gerhard AnderssonAbstract:Objectives Evaluating and comparing the effectiveness of two Smartphone-delivered treatments: one based on behavioural activation (BA) and other on mindfulness. Design Parallel randomised controlled, open, trial. Participants were allocated using an online randomisation tool, handled by an independent person who was separate from the staff conducting the study. Setting General community, with recruitment nationally through mass media and advertisements. Participants 40 participants diagnosed with major depressive disorder received a BA treatment, and 41 participants received a mindfulness treatment. 9 participants were lost at the post-treatment. Intervention BA: An 8-week long behaviour programme administered via a Smartphone Application. Mindfulness: An 8-week long mindfulness programme, administered via a Smartphone Application. Main outcome measures The Beck Depression Inventory-II (BDI-II) and the nine-item Patient Health Questionnaire Depression Scale (PHQ-9). Results 81 participants were randomised (mean age 36.0 years (SD=10.8)) and analysed. Results showed no significant interaction effects of group and time on any of the outcome measures either from pretreatment to post-treatment or from pretreatment to the 6-month follow-up. Subgroup analyses showed that the BA treatment was more effective than the mindfulness treatment among participants with higher initial severity of depression from pretreatment to the 6-month follow-up (PHQ-9: F (1, 362.1)=5.2, p Conclusions The two interventions did not differ significantly from one another. For participants with higher severity of depression, the treatment based on BA was superior to the treatment based on mindfulness. For participants with lower initial severity, the treatment based on mindfulness worked significantly better than the treatment based on BA. Trial registration Clinical Trials NCT01463020.

behavioral activation based guided self help treatment administered through a Smartphone Application study protocol for a randomized controlled trial
Trials, 2012Co-Authors: Per Carlbring, Gerhard AnderssonAbstract:Background: The need for cost-effective interventions for people suffering from major depressive disorders is essential. Behavioral activation is an intervention that can largely benefit from the use of new mobile technologies (for example Smartphones). Therefore, developing Smartphone-based behavioral activation interventions might be a way to develop cost-effective treatments for people suffering from major depressive disorders. The aim of this study will be to test the effects of a Smartphone-delivered behavioral activation treatment. Methods: The study will be a randomized controlled trial with a sample size of 120 participants, with 60 patients in each group. The treatment group includes an 8-week Smartphone-based behavioral activation intervention, with minimal therapist contact. The Smartphone-based intervention consists of a web-based psychoeducation, and a Smartphone Application. There is also a back-end system where the therapist can see reports from the patients or activities being reported. In the attention control group, we will include brief online education and then recommend use of a Smartphone Application that is not directly aimed at depression (for example, ‘Effective meditation’). The duration of the control condition will also be 8 weeks. For ethical reasons we will give the participants in the control group access to the behavioral activation treatment following the 8-week treatment period. Discussions: We believe that this trial has at least three important implications. First, we believe that Smartphones can be integrated even further into society and therefore may serve an important role in health care. Second, while behavioral activation is a psychological treatment approach for which there is empirical support, the use of a Smartphone Application could serve as the therapist’s prolonged arm into the daily life of the patient. Third, as we have been doing trials on guided Internet treatment for more than 10 years it is now time to move to the next generation of information technology - Smartphones - which are not only relevant for Swedish conditions but also for developing countries in the world which are increasingly empowered by mobile phones with Internet connection.

a Smartphone Application to objectively monitor music listening habits in adolescents personal listening device usage and the accuracy of self reported listening habits
Journal of Otolaryngology-head & Neck Surgery, 2021Co-Authors: Danique E Paping, Jantien L Vroegop, Simone P C Koenraads, Carlijn Le M P Clercq, Andre Goedegebure, Robert Baatenburg J De Jong, Marc P Van Der SchroeffAbstract:Listening to music through personal listening devices (PLDs) has become more prevalent during last decades. The aim of this study was to evaluate music listening habits through PLDs in adolescents with a Smartphone Application, and to assess the accuracy of self-reported listening habits. This study was embedded in the Generation R Study, a population-based prospective birth cohort in Rotterdam, the Netherlands. A Smartphone Application for Android operating systems was developed to objectively monitor music listening habits for a period of 35 days. A postal questionnaire was used to subjectively assess listening habits. The level of agreement between the objectively measured and self-reported listening habits were evaluated using weighted kappa coefficients. Data were collected from May 2017 to March 2019. A total of 311 adolescents aged 12 to 15 years were included, of whom 237 (76.2%) completed the postal questionnaire. The results of the Smartphone Application showed that the median listening frequency was 2.1 days a week (IQR 1.0–3.4), the median listening time 21.1 min a day (IQR 9.1–53.7), and the mean listening level 54.5% (SD 18.1%). There was a slight to fair agreement between the objectively measured, and self-reported listening habits according to the weighted kappa coefficients (k = 0.179 to 0.364). The results of the current study suggest that self-reported measures of listening habits are not always accurate. We consider a Smartphone Application to monitor listening habits of added value in future research investigating the possible damaging effects of PLDs on hearing acuity.
