MUNDUS is an assistive framework for recovering direct interaction capability of severely motor impaired people based on arm reaching and hand functions. It aims at achieving personalization, modularity maximization the user’s involvement in systems. To this, exploits any residual control end-user can be adapted to level severity or progression disease allowing user voluntarily interact with environment. target pathologies are high-level spinal cord injury (SCI) neurodegenerative genetic...
Reaching and grasping impairments significantly affect the quality of life for people who have experienced a stroke or spinal cord injury. The long-term well-being patients varies greatly according to restorable residual capabilities. Electrical stimulation could be promising solution restore motor functions in these conditions, but its use is not clinically widespread. Here, we introduce HandNMES, an electrode array (EA) neuromuscular electrical (NMES) aimed at grasp training assistance....
The continuous stream of multisensory information between the brain and body during body-environment interactions is crucial to maintain updated representation perceived dimensions parts (metric representation) space around (the peripersonal space). Such flow signals often limited by upper limb sensorimotor deficits after stroke. This would suggest presence systematic distortions metric in chronic patients with persistent deficits. We assessed 60 stroke unilateral motor deficits, comparison...
Effective, patient-tailored rehabilitation to restore upper-limb motor function in severely impaired stroke patients is still missing. If suitably combined and administered a personalized fashion, neurotechnologies offer large potential assist rehabilitative therapies enhance individual treatment effects. AVANCER (clinicaltrials.gov NCT04448483) two-center proof-of-concept trial with an based cumulative longitudinal intervention design aiming at reducing impairment affected the help of...
Clinicians constantly face the need to rehabilitate stroke patients re-establish coordinate reach and grasp. Rehabilitation, be effective, requires intensive repetitive tasks. Assist-as-needed motion control for grasp assistance are usually treated separately, mostly based on virtual reality games. To increase clinical outcome, we designed flexible modules a platform, able provide synchronous support interact with common objects. An upper limb exoskeleton provides reaching support,...
Active functional rehabilitation procedures, exoskeleton application and prosthesis employment are essential tools for the society life reinstatement of subjects affected by neuromuscular disorders or victims serious physical accident. In this paper we propose a closed-loop system control Functional Electrical Stimulation (FES) based on Average Threshold Crossing (ATC) event-driven processing technique applied to sEMG signal. It allows an energy saving, low complex, real-time muscle activity...
The paper presents a multisensory and multimodal device for neuromuscular rehabilitation of the upper limb, designed to enable enriched treatment in both clinical home environments. Originating from an existing low-cost, variable-stiffness device, it expands its functionalities by integrating additional modules order augment application scenarios applicable techniques. newly developed system focuses on integration wearable electrical stimulation system, virtual scenario, low-cost unobtrusive...
Many research groups are currently working with robotic devices for hand grasp rehabilitation and restoration. A common problem in this area is the fact that existing commercially available exoskeletons able to provide gravity compensation of shoulder elbow but do not any support grasping releasing movements hand. The lack a flexible technology reduces possible ways which clinicians can deal issue personalized, effective rehabilitation. This paper presents new software allows FES assisted...
Muscle synergies have been proposed as building blocks that simplify the construction of movements, and a method to study motor behavior. However, pre-processing EMG signals factorization algorithm may impact on their extraction meaning. This preliminary work aimed at investigating influence selection muscles muscle analysis. In particular, extracted from datasets including different upper limb muscles, recorded during execution planar reaching grasping movements. Results suggested amount...
Exosuits typically provide limited mechanical support and rely on a user's residual functional ability. However, people with neurological impairments often suffer from both motor sensory deficits that limit the assistance an exosuit can provide. To overcome these limitations, we developed REINFORCE system, complements provided by exosuit, Myosuit, (1) electrical stimulation to enhance activities of leg muscles, (2) transcutaneous nerve restore somatosensory information. It consists fully...
Enriched environments and tools are believed to promote grasp rehabilitation after stroke. We designed S2, an interactive system consisting of smart objects, custom orthoses for selective constraining, electrode array forearm NMES. Motor improvements perceived usability a new enriched upper limb training sub-acute stroke patients was assessed in this interim analysis. Inclusion criteria: with MMSE>20, ipsilesional MI>80%, contralesional MI<80%. Effects 30-min therapy supplements,...
The Helping Hand (HH) system is a novel grasp rehabilitation platform aimed at simplifying the clinical usage of wearable electrode arrays for neuromuscular electrical stimulation (NMES). In randomized dose-matched, study we evaluate usability and effectiveness HH treatment, other enriched upper limb treatments, compare outcomes. This paper shows preliminary results trial on 5 chronic stroke patients throughout 9 weeks, 3 hours per week, hand preshaping training.
The paper presents a multisensory and multimodal device for neuromuscular rehabilitation of the upper limb. system integrates variable-stiffness device, wearable electrical stimulation system, virtual environment, low-cost unobtrusive sensory patient model adapting training task parameters. It monitors user behaviour its evolution throughout entire period. enables patients, integrating features currently unavailable in single off-the-shelf devices upper-limb rehabilitation.
Stroke is the leading cause of long term disability, causing both motor and cognitive impairments. impacts somatosensory capabilities individual, distorted perception environment body. Consequently persons with grasp impairments are subject to activity limitations participation restriction because perceptive reduced control affected limb. Recent medical research has demonstrated that contextual matching intent rehabilitation assistance a decisive factor for success therapies involve...
