Digital Health, Wearable technology and Devices

Recently we have been studying human walking and trying to understand its various components.Human walking seems so simple as shown in the video below by phsiotutors, but is a very complex activity. It involves multiple muscle movements coordinated into a seamless activity that is a balancing act on two legs accompanied by forward motion. Walking…

There has been significant discussion on who owns medical data. The hospital or service that collects the data or the patients themselves? Then there are questions about how do we manage the data – who manages the data? Security issues? Exchange and storage? And more importantly business issues on who commercializes the data – who…

Wearable for digital health requires communication strategy: IOT and LORAWANAn ideal wearable digital health system has these 3 top requirements:1.    Simple – No complicated setup and automated data collection procedure 2.    Long measurement – Ability to collect data over extended periods3.    Actionable data that is securely stored or sent to a databaseDigital health technologies have…

Many research studies have incorporated the use of wearable devices into the study to measure the activity of humans in response to a variety of interventions. There are grossly three parts to that process:1.    Selection and adoption of the activity monitor – accelerometer or gyroscope based devices2.    Process for collection of the data – supervised…

We think of digital health in terms of devices or phones that are meant to track a measure of the body or our health. However, there have been several portable tools and toys that are being made that enable you to monitor what you eat and what you consume. The device list with many fluorescent…

There have been various models of sharing of health data, maintaining privacy and still maintaining HIPAA regulations. Big companies have tried to bring it all under their umbrella including Google, Apple and Amazon. However, this has not led to much success. The winner’s in this competition has usually being the software companies that offer Electronic…

We develop run clinical trials with different devices including our own prototypes and many of our clients seem lost with the number of things that need to be planned. Eventually, we help them through the various phases and only now have some of them begun to get data from their studies and analyze the data….

Range: First, since the accelerometer measures acceleration, it is important that the range of the accelerometer should be well within the range of the activity that we need to measure. What is the range of human acceleration? As the last article pointed out, the fastest runner in the world can generate nearly 1g whereas a…

Accelerometers are used very often in digital health devices. Let us try to understand them better but before that lets understand acceleration since that is what they measure. Acceleration:Let’s consider a runner in a 100m dash like the fast runner, Usain Bolt. He can rapidly accelerate from zero to nearly 27 miles per hour which…

Many studies in digital health use accelerometers that are worn on the wrist to track activity of the person. This activity is measured through the day and then a score is computed for the person to express their score: activity to sedentary ratio. In consumer world, this is expressed as some measure – say the…
