How many decades before this gets to your hospital? But would it correct the spastic turning outward of the foot like I have? Followup research on exact diagnosis needed for this to help will probably never occur.

A softer recovery after stroke
Passive
assistance devices such as canes and braces are often used by people
after stroke, but mobility remains limited for some patients. Awad et al.
studied the effects of active assistance (delivery of supportive force)
during walking in nine patients in the chronic phase of stroke
recovery. A soft robotic exosuit worn on the partially paralyzed lower
limb reduced interlimb propulsion asymmetry, increased ankle
dorsiflexion, and reduced the energy required to walk when powered on
during treadmill and overground walking tests. The exosuit could be
adjusted to deliver supportive force during the early or late phase of
the gait cycle depending on the patient’s needs. Although long-term
therapeutic studies are necessary, the immediate improvement in walking
performance observed using the powered exosuit makes this a promising
approach for neurorehabilitation.
Abstract
Stroke-induced
hemiparetic gait is characteristically slow and metabolically
expensive. Passive assistive devices such as ankle-foot orthoses are
often prescribed to increase function and independence after stroke;
however, walking remains highly impaired despite—and perhaps because
of—their use. We sought to determine whether a soft wearable robot
(exosuit) designed to supplement the paretic limb’s residual ability to
generate both forward propulsion and ground clearance could facilitate
more normal walking after stroke. Exosuits transmit mechanical power
generated by actuators to a wearer through the interaction of
garment-like, functional textile anchors and cable-based transmissions.
We evaluated the immediate effects of an exosuit actively assisting the
paretic limb of individuals in the chronic phase of stroke recovery
during treadmill and overground walking. Using controlled,
treadmill-based biomechanical investigation, we demonstrate that
exosuits can function in synchrony with a wearer’s paretic limb to
facilitate an immediate 5.33 ± 0.91° increase in the paretic ankle’s
swing phase dorsiflexion and 11 ± 3% increase in the paretic limb’s
generation of forward propulsion (P < 0.05). These
improvements in paretic limb function contributed to a 20 ± 4% reduction
in forward propulsion interlimb asymmetry and a 10 ± 3% reduction in
the energy cost of walking, which is equivalent to a 32 ± 9% reduction
in the metabolic burden associated with poststroke walking. Relatively
low assistance (~12% of biological torques) delivered with a lightweight
and nonrestrictive exosuit was sufficient to facilitate more normal
walking in ambulatory individuals after stroke. Future work will focus
on understanding how exosuit-induced improvements in walking performance
may be leveraged to improve mobility after stroke.
It will help the spastic turning out of your foot. The position of the cables can be manipulated to match the needs of individual patients!
