HMC Research Projects Develop Wearable Technology for Diabetics

A collaborative research project brings together four separate studies that has led to the development of innovative, wearable devices which could enhance the prevention, management, and treatment of diabetic foot ulcers.

The studies, which were completed over a ten-year period and carried out by researchers at Hamad Medical Corporation (HMC), in partnership with Qatar Foundation and several institutions in the United States, won the Best Research Project Award at Qatar Foundation’s Annual Research Conference earlier this year.

According to Dr Talal Khader Talal, Head of Podiatric Services at HMC and a lead author of the studies, between 10 and 20 percent of people with diabetes will likely develop a foot ulcer at some point in their life.

People with diabetes are especially vulnerable to foot ulcers as their blood sugar levels are often high and can fluctuate. This can inhibit the skin’s ability to repair itself due to nerve damage. Due to a condition called peripheral diabetic neuropathy, many diabetics have reduced nerve function and sensation in their feet, meaning they may be unaware of cuts, damage, and ulcers on their feet until they become severe.’

The International Diabetes Federation estimates that around 23% of Qatar’s population has diabetes, with diabetic foot ulcers being the main reason for hospitalisation for people with diabetes. HMC’s podiatry clinics treat thousands of patients with diabetes each year, with nearly 15,000 diabetes-related appointments in 2017 alone.

The information is sent automatically to a specialised device and can be viewed by both the patient and their doctor.

By monitoring this information via the ‘smart sock’, we are able to predict when a patient may be most vulnerable to the development of a foot ulcer. We are then able to help the patient change their behaviour and minimise this risk.’

In another study, the researchers designed a specialist shirt capable of monitoring the patients activity. Physical activity is an important component of managing diabetes but it can be challenging to get the right balance: high levels of activity can cause stress and pressure on the feet, while low activity levels may increase the risk of foot ulcers.

Our research also focused on enhancing the treatment of diabetic foot ulcers and one of the studies lead to the development of wearable units which can be used to send electro impulses to the feet to stimulate blood flow and increase healing. In addition to the positive healing effect, the impulses are also able to increase sensation in the feet.’

The final study looked at the effect of sensor-based interactive balance training. Due to the loss of feeling in their feet, some patients with diabetes experience mobility issues and lose confidence. The interactive balance training uses sensors and a computer-based avatar which navigates obstacles. This provided a safe way for patients to gain confidence in their mobility.

Though the devices developed are still undergoing further investigation, according to Dr Talal, their initial research findings indicate that they could become very valuable tools in the future and boost their ability to prevent, manage, and treat diabetic foot ulcers.
