Computer Used To Say No, Now AI Says No!

ARNI Institute for Stroke Rehabilitation — Tue, 01 Sep 2026 19:27:09 +0000

The NHS is moving its first point of contact from human to machine, and stroke survivors are among the first to find where it fails! The system in the current row about AI is EMMA (Enhanced Medical Management Assistant), a virtual receptionist from QuantumLoopAI, used across many UK GP practices to triage calls, cut queues

Restoring Upper Limb Control via Spinal Cord Stimulation

ARNI Institute for Stroke Rehabilitation — Tue, 11 Aug 2026 14:05:12 +0000

If your arm and hand have been left weak by a stroke, you’ll know it’s often the last thing to recover, and standard rehabilitation has surprisingly little to offer once you plateau. So this pilot trial from the University of Pittsburgh, published in Nature Medicine on 4 June 2026, caught my eye. Seven people with

Stroke Recovery With a 90’s-style Video Game!

ARNI Institute for Stroke Rehabilitation — Mon, 10 Aug 2026 20:01:40 +0000

After a stroke, a common cause of a stiff, hard-to-control upper limb is something called abnormal co-activation, or coupling; muscles that should fire separately instead fire together, so when you try to do one movement you might get an unwanted second one bundled in with it. The brain’s movement signals have, in effect, become ‘tangled’.

Gel Packing Which Could Repair Stroke Damage

A large stroke often leaves a permanent hole in the brain. Once the dead tissue is cleared away you’re left with a cavity, and up to now that’s been seen as permanent damage that can’t be undone or resolved, with rehab as the only possible solution. But a team at Duke University, led by Professor

AI-Driven Physical Therapy After Stroke?

ARNI Institute for Stroke Rehabilitation — Wed, 05 Aug 2026 15:00:40 +0000

Most ‘rehabotics’ (rehab-robotics) so far has been good at one thing and poor at another. It can move a limb along a set path well enough, but it really struggles with the part a human therapist would do instinctively; sensing how much resistance to give, when to yield, when to push and adjusting all of

From Locked-In Stroke to the Top of Snowdon

ARNI Institute for Stroke Rehabilitation — Mon, 03 Aug 2026 14:19:40 +0000

Peter Coghlan’s recovery story is one of the more remarkable you’ll come across. In 2011, aged just 33, this former soldier had a massive brain stem stroke and woke from a coma with locked-in syndrome; fully conscious and aware, but unable to move or speak. He could blink, and that was all. Imagine lying there,

Spotting Spatial Neglect After Stroke

ARNI Institute for Stroke Rehabilitation — Fri, 24 Jul 2026 13:27:29 +0000

If you’ve had a stroke on the right side of the brain, you may well have come across a problem called spatial neglect, which is where the brain stops attending to everything on your left. It isn’t actually blindness; your eyes work perfectly well, but the brain no longer registers one side of the world.

A Magnetic Robot That Steers Through the Brain to Treat Stroke

ARNI Institute for Stroke Rehabilitation — Mon, 20 Jul 2026 11:11:56 +0000

How about this; imagine a soft, hair-thin thread being steered through the twisting blood vessels of the brain by a magnet held outside the skull, clearing the clot that caused a stroke. Science fiction, right?! But amazingly, it’s being built right now, by a team at MIT and a spinout called Magnendo led by Dr

ZFP384 and the Brain’s Repair Window After Stroke

ARNI Institute for Stroke Rehabilitation — Wed, 15 Jul 2026 16:33:57 +0000

After a stroke, the brain runs a repair programme of its own. The microglia, the brain’s resident immune cells, switch out of their initial inflammatory state and into a reparative one, producing growth factors such as insulin-like growth factor 1 (IGF1) that rebuild myelin around damaged nerve fibres and strengthen synaptic connections. This is a

An ARNI Guide to the 10 Rarest Strokes

ARNI Institute for Stroke Rehabilitation — Wed, 08 Jul 2026 14:48:38 +0000

In this post, I’m going to run through ten of the rarer stroke types, ordered from the least rare down to the rarest. For each one I’ve given the approximate share of all UK strokes it represents, and a rough number of people affected each year, working from the figure of roughly 100,000 strokes annually
