mhealth Evidence
Permanent URI for this collection
mHealth Evidence was launched in 2012 to bring together the world’s literature on “mHealth” (broadly speaking, the application of mobile technologies to health service delivery). The collection was intended to help program managers, researchers, government leaders, donors, software developers, and other key decision-makers quickly get up to speed on the current state-of-the-art and evidence-based best practices. It included 11,000 bibliographic records of peer-reviewed and gray literature from low-, middle- and high-resource settings, with basic and advanced search. The database categorized evidence according to a taxonomy developed in partnership with the World Health Organization’s mHealth Technical and Evidence Review Group (mTERG).

- ItemBrain-muscle-computer interface: mobile-phone prototype development and testing.(2011-07-19) Vernon, Scott; Joshi, Sanjay SWe report prototype development and testing of a new mobile phone based brain muscle computer interface for severely paralyzed persons based on previous results from our group showing that humans may actively create specified power levels in two separate frequency bands of a single surface electromyography sEMG signal EMG activity on the surface of a single face muscle site auricularis superior is recorded with a standard electrode This analog electrical signal is imported into an Android based mobile phone and digitized via an internal A D converter The digital signal is split and then simultaneously filtered with two band pass filters to extract total power within two separate frequency bands The user modulated power in each frequency band serves as two separate control channels for machine control After signal processing the Android phone sends commands to external devices via a Bluetooth interface Users are trained to use the device via visually based operant conditioning with simple cursor to target activities on the phone screen The mobile phone prototype interface is formally evaluated on a single advanced Spinal Muscle Atrophy subject who has successfully used the interface in his home in evaluation trials and for remote control of a television Development of this new device will not only guide future interface design for community use but will also serve as an information technology bridge for in situ data collection to quantify human sEMG manipulation abilities for a relevant population
- ItemCan individualized weight monitoring using the HeartPhone algorithm improve sensitivity for clinical deterioration of heart failure?(2013-03-25) Ledwidge, Mark T; O'Hanlon, Rory; Lalor, Lorraine; Travers, Bronagh; Edwards, Nuala; Kelly, Deirdre; Voon, Victor; McDonald, Kenneth MAIMS Previous studies have demonstrated poor sensitivity of guideline weight monitoring in predicting clinical deterioration of heart failure HF This study aimed to evaluate patterns of remotely transmitted daily weights in a high risk HF population and also to compare guideline weight monitoring and an individualized weight monitoring algorithm METHODS AND RESULTS Consenting consecutive high risk patients were provided with a mobile phone based remote weight telemonitoring device We aimed to evaluate population vs individual weight variability weight patterns pre and post events of clinical deterioration of HF and to compare guideline weight thresholds with the HeartPhone algorithm in terms of sensitivity and specificity for such events Of 87 patients recruited and followed for an average of 23 9 12 weeks 19 patients experienced 28 evaluable episodes of clinical deterioration of HF Following a post discharge decline the population average weight remained stable for the follow up period yet the 7 day moving average of individual patients exceeded 2 kg in three quarters of patients Significant increases in weight were observed up to 4 days before HF events The HeartPhone algorithm was significantly more sensitive 82 in predicting HF events than guideline weight thresholds of 2 kg over 2 3 days 21 and a rule of thumb threshold of 1 36 kg over 1 day 46 CONCLUSIONS An individualized approach to weight monitoring in HF with the HeartPhone algorithm improved prediction of HF deterioration Further evaluation of HeartPhone with and without other biomarkers of HF deterioration is warranted

- ItemA randomized controlled trial on the efficacy of carbohydrate-reduced or fat-reduced diets in patients attending a telemedically guided weight loss program.(2009-08-07) Frisch, Sabine; Zittermann, Armin; Berthold, Heiner K; Götting, Christian; Kuhn, Joachim; Kleesiek, Knut; Stehle, Peter; Körtke, HeinrichBACKGROUND We investigated whether macronutrient composition of energy restricted diets influences the efficacy of a telemedically guided weight loss program METHODS Two hundred overweight subjects were randomly assigned to a conventional low fat diet and a low carbohydrate diet group target carbohydrate content 55 energy and Under40 energy respectively Both groups attended a weekly nutrition education program and dietary counselling by telephone and had to transfer actual body weight data to our clinic weekly with added Bluetooth technology by mobile phone Various fatness and fat distribution parameters energy and macronutrient intake and various biochemical risk markers were measured at baseline and after 6 and 12 months RESULTS In both groups energy intake decreased by 400 kcal d compared to baseline values within the first 6 months and slightly increased again within the second 6 months Macronutrient composition differed significantly between the groups from the beginning to month 12 At study termination weight loss was 5 8 kg SD 6 1 kg in the low carbohydrate group and 4 3 kg SD 5 1 kg in the low fat group p 0 065 In the low carbohydrate group triglyceride and HDL cholesterol levels were lower at month 6 and waist circumference and systolic blood pressure were lower at month 12 compared with the low fat group P 0 005 0 037 Other risk markers improved to a similar extent in both groups CONCLUSION Despite favourable effects of both diets on weight loss the carbohydrate reduced diet was more beneficial with respect to cardiovascular risk factors compared to the fat reduced diet Nevertheless compliance with a weight loss program appears to be even a more important factor for success in prevention and treatment of obesity than the composition of the diet TRIAL REGISTRATION Clinicaltrials gov as NCT00868387
