Wearable support for patients with Duchenne muscular dystrophy

Wearable assistive device for patients with DMD

Solid Biosciences is proudly partnering with Silicon Valley’s Seismic, along with other engineering and disease experts to develop a line of soft, wearable assistive devices for patients with Duchenne muscular dystrophy.

Engaging the patient community

Our goal is to develop devices with functional and potential therapeutic benefits that help patients perform day-to-day activities with greater ease. Research is currently being carried out at Seismic’s robotics lab and several clinics and is guided by the patient community.

Solid conceived the program with the help of a coalition of leading robotics specialists, clinicians and muscle biologists, which assessed patients’ physical needs and surveyed current state-of-the-art technology. To help inform design and functionality, we worked closely with the advocacy group Parent Project Muscular Dystrophy (PPMD), a sponsor of the initial development phase.

As the program progresses, Solid continues to gain critical feedback from clinicians, parents and children with muscular dystrophy to guide prototype development, with the ultimate goal of ensuring widespread benefit and access to the technology.

Cutting-edge innovations

Employing robotic technologies, Solid aims to produce a series of wearable assistive devices for patients with Duchenne muscular dystrophy.

The innovations driving this program are derived from cutting-edge military technologies that power soft exoskeletons to offset muscle fatigue and augment muscle strength.

Solid’s assistive devices are being designed for wearer comfort, durability, energy efficiency and affordability.

The hardware is composed of three key technologies: force generating actuators motors, electrically controlled clutches and comfortable harnesses.

Assistive Device Components

Design criteria

From the outset, a driving principle of the assistive device program has been to create low profile products that conform to patients’ bodies, potentially allowing them to benefit from the latest advances in robotic technology without the cost, stigma and inconvenience of existing hard exoskeleton devices.

Integrating the core technology with textiles and sensors, these assistive devices are being designed for wearer comfort, durability, energy efficiency and affordability.

Another key design approach has been to make assistive devices modular through a series of complementary components.  This strategy will hopefully allow users to mix and match components according to their individual needs. In addition, this strategy has the potential to enable the release of individual components as soon as they are ready without having to wait until the entire project is completed, speeding availability to the community.  These components include:

Upper Body Mobility and Functional support

Assist Bring hand to face Access surroundings
  • Eating
  • Wiping nose / scratch
  • Adjust glasses
  • Computer peripherals
  • Countertop items
  • Tablets / phones

Lower Body Stretch Assist

Stretching is the most important preventative therapy for fibrosis. The device will be designed to actively stretch posterior muscles and tendons by providing adjustable dynamic tension.

A dynamic lower body support system

Designed to dramatically improve mobility and quality of life for boys who have lost the ability to walk. This device is a long-term goal for Solid Biosciences.
