Neubond Wristband That Detects Your Intention to Move

I’ve detailed Neubond on this Blog before – good news.. it’s on its way! As you know so well, after stroke, trying to move your affected hand and feeling nothing happen is one of the most frustrating experiences you can have… ut because the link between the brain’s intention to move and the sensory feedback that confirms movement has broken down.

Neubond, an Imperial College London spinout founded by Dr Patrick Sagastegui Alva, Jumpei Kashiwakura and Professor Dario Farina (head of Imperial’s Neuromechanics and Rehabilitation Technology lab, whose team spent over a decade developing the core science), has just announced a £1.5 million seed funding round led by Waseda University Ventures (its first investment in a UK company), alongside SFC Capital and New Wave Ventures, to finalise its wearable stroke rehabilitation platform and complete a pivotal clinical study at Charing Cross Hospital.

The device is basically a compact bracelet worn on the forearm. Sensors inside detect faint electrical signals from muscles even when the patient cannot see or feel any movement occurring; when the bracelet picks up a signal, a companion app shows the patient in real time that their muscle has activated, closing the sensory feedback loop that stroke has opened. As Professor Farina puts it: ‘we have strong evidence that neuroplasticity can be induced by detecting a motor command and applying artificial sensory feedback… guiding the brain to remake connections.’ The tech originated from prosthetic hand interface research; Sagastegui and Kashiwakura realised the detection component had an independent clinical application for stroke rehabilitation and built from there.

In a pilot with 15 patients, range of motion improved by 30% after one month. These are early numbers from a small sample; the Charing Cross study will provide the larger dataset needed to inform a full clinical trial and MHRA approval. The funding also completes product development toward a device that can be used at home independently and monitored remotely by clinicians… which addresses one of the most persistent gaps in stroke rehab: what continues (or more commonly does not continue) after hospital discharge. Co-founder Kashiwakura is direct about the aim: ‘motivation is vital for stroke patients; our platform uses a simple biofeedback mechanism so that patients can see the effect their rehabilitation efforts are having.’

Neubond is of course not yet available and MHRA approval is still ahead; routine availability is realistically several years away.
