Researchers at Harvard John A. Paulson Faculty of Engineering and Utilized Sciences developed a mushy exoskeleton to assist an individual with Parkinson’s stroll with out freezing. Freezing of gait (FOG) is a typical, but poorly understood, symptom of Parkinson’s illness. It causes sudden and involuntary episodes of immobility that may happen throughout strolling, usually resulting in falls and accidents. Conventional remedies for FOG, resembling medicine changes and bodily remedy, have had restricted success.
The researchers spent six months working with a 73-year-old man with Parkinson’s illness. Regardless of utilizing each surgical and pharmacologic remedies, he endured substantial and incapacitating FOG episodes greater than 10 instances a day. These episodes prevented him from strolling round his neighborhood and compelled him to depend on a scooter to get round outdoors.
The exoskeleton makes use of cable-driven actuators and sensors worn across the waist and thighs. Utilizing movement information collected by the sensors, algorithms estimate the part of the gait and generate assistive forces in tandem with muscle motion.
With none particular coaching, the affected person was immediately capable of stroll with none freezing indoors and with solely occasional episodes outdoor. He was additionally capable of stroll and discuss with out freezing, a rarity with out the gadget.
Harvard collaborated on this challenge with Boston College.
“This work suggests the potential advantages of a ‘bottom-up’ somewhat than ‘top-down’ resolution to treating gait freezing,” stated the researchers. “We see that restoring almost-normal biomechanics alters the peripheral dynamics of gait and should affect the central processing of gait management.”
The analysis demonstrates the potential of exoskeletons to deal with FOG and provides hope to these with Parkinson’s illness. It might assist them regain their mobility and independence.
