A quantitative taxonomy of human hand grasps.

J Neuroeng Rehabil 2019 Feb 15;16(1):28. Epub 2019 Feb 15.

Information Systems Institute, University of Applied Sciences Western Switzerland (HES-SO), Sierre, Switzerland.

Background: A proper modeling of human grasping and of hand movements is fundamental for robotics, prosthetics, physiology and rehabilitation. The taxonomies of hand grasps that have been proposed in scientific literature so far are based on qualitative analyses of the movements and thus they are usually not quantitatively justified.

Methods: This paper presents to the best of our knowledge the first quantitative taxonomy of hand grasps based on biomedical data measurements. Read More

Uneven terrain exacerbates the deficits of a passive prosthesis in the regulation of whole body angular momentum in individuals with a unilateral transtibial amputation.

J Neuroeng Rehabil 2019 Feb 4;16(1):25. Epub 2019 Feb 4.

Department of Biomechanics and Center for Research in Human Movement Variability, College of Education, University of Nebraska at Omaha, 6160 University Drive South, Omaha, NE, 68182-0860, USA.

Background: Uneven ground is a frequently encountered, yet little-studied challenge for individuals with amputation. The absence of control at the prosthetic ankle to facilitate correction for surface inconsistencies, and diminished sensory input from the extremity, add unpredictability to an already complex control problem, and leave limited means to produce appropriate corrective responses in a timely manner. Whole body angular momentum, L, and its variability across several strides may provide insight into the extent to which an individual can regulate their movement in such a context. Read More

Design, development, and evaluation of a local sensor-based gait phase recognition system using a logistic model decision tree for orthosis-control.

J Neuroeng Rehabil 2019 Feb 1;16(1):22. Epub 2019 Feb 1.

Ottawa Hospital Research Institute, Ottawa, ON, K1H8M2, Canada.

Background: Functionality and versatility of microprocessor-controlled stance-control knee-ankle-foot orthoses (M-SCKAFO) are dictated by their embedded control systems. Proper gait phase recognition (GPR) is required to enable these devices to provide sufficient knee-control at the appropriate time, thereby reducing the incidence of knee-collapse and fall events. Ideally, the M-SCKAFO sensor system would be local to the thigh and knee, to facilitate innovative orthosis designs that allow more flexibility for ankle joint selection and other orthosis components.

Altered muscle activation patterns (AMAP): an analytical tool to compare muscle activity patterns of hemiparetic gait with a normative profile.

J Neuroeng Rehabil 2019 Jan 31;16(1):21. Epub 2019 Jan 31.

Department of Health Sciences and Research, College of Health Professions, Medical University of South Carolina, 77 President Street, Charleston, SC, 29425, USA.

Background: Stroke survivors often have lower extremity sensorimotor impairments, resulting in an inability to sufficiently recruit muscle activity at appropriate times in a gait cycle. Currently there is a lack of a standardized method that allows comparison of muscle activation in hemiparetic gait post-stroke to a normative profile.

Methods: We developed a new tool to quantify altered muscle activation patterns (AMAP). Read More

Transcranial direct current stimulation for the treatment of motor impairment following traumatic brain injury.

J Neuroeng Rehabil 2019 Jan 25;16(1):14. Epub 2019 Jan 25.

Department of Rehabilitation Medicine, Seoul National University College of Medicine, Seoul National University Bundang Hospital, 82, Gumi-ro 173 Beon-gil, Bundang-gu, Seongnam-si, Gyeonggi-do, 13620, Republic of Korea.

After traumatic brain injury (TBI), motor impairment is less common than neurocognitive or behavioral problems. However, about 30% of TBI survivors have reported motor deficits limiting the activities of daily living or participation. After acute primary and secondary injuries, there are subsequent changes including increased GABA-mediated inhibition during the subacute stage and neuroplastic alterations that are adaptive or maladaptive during the chronic stage.

Adapting myoelectric control in real-time using a virtual environment.

J Neuroeng Rehabil 2019 Jan 16;16(1):11. Epub 2019 Jan 16.

Center for Bionic Medicine, Shirley Ryan Ability Lab, Chicago, IL, 60611, USA.

Background: Pattern recognition technology allows for more intuitive control of myoelectric prostheses. However, the need to collect electromyographic data to initially train the pattern recognition system, and to re-train it during prosthesis use, adds complexity that can make using such a system difficult. Although experienced clinicians may be able to guide users to ensure successful data collection methods, they may not always be available when a user needs to (re)train their device. Read More

A modified standardized nine hole peg test for valid and reliable kinematic assessment of dexterity post-stroke.

J Neuroeng Rehabil 2019 Jan 14;16(1). Epub 2019 Jan 14.

Department of Community Medicine and Rehabilitation; Physiotherapy, Umeå University, Umeå, Building 15, Umeå University, SE-901 87, Umeå, Sweden.

Background: Impairments in dexterity after stroke are commonly assessed by the Nine Hole Peg Test (NHPT), where the only outcome variable is the time taken to complete the test. We aimed to kinematically quantify and to compare the motor performance of the NHPT in persons post-stroke and controls (discriminant validity), to compare kinematics to clinical assessments of upper extremity function (convergent validity), and to establish the within-session reliability.

Methods: The NHPT was modified and standardized (S-NHPT) by 1) replacing the original peg container with an additional identical nine hole pegboard, 2) adding a specific order of which peg to pick, and 3) specifying to insert the peg taken from the original pegboard into the corresponding hole of the target pegboard.

Fixed muscle synergies and their potential to improve the intuitive control of myoelectric assistive technology for upper extremities.

J Neuroeng Rehabil 2019 Jan 7;16(1). Epub 2019 Jan 7.

Center for Human Movement Sciences, University of Groningen, University Medical Center Groningen, Antonius Deusinglaan 1, 9713, AV, Groningen, the Netherlands.

Background: Users of myoelectric controlled assistive technology (AT) for upper extremities experience difficulties in controlling this technology in daily life, partly because the control is non-intuitive. Making the control of myoelectric AT intuitive may resolve the experienced difficulties. The present paper was inspired by the suggestion that intuitive control may be achieved if the control of myoelectric AT is based on neuromotor control principles. Read More

Gait variability following abrupt removal of external stabilization decreases with practice in incomplete spinal cord injury but increases in non-impaired individuals.

J Neuroeng Rehabil 2019 Jan 7;16(1). Epub 2019 Jan 7.

Department of Physical Therapy and Human Movement Sciences, Feinberg School of Medicine, Northwestern University, Chicago, IL, USA.

Background: Individuals with incomplete spinal cord injury (iSCI) exhibit considerable lateral center of mass (COM) movement variability during gait transitions from a stabilizing to unassisted environment, while non-impaired individuals do not. To understand how iSCI influences gait adaption, we examined persons with and without iSCI performing repeated locomotor transitions. We hypothesized that, with practice, individuals with iSCI would prioritize COM control performance during the transition as exhibited by a reduction in kinematic variability. Read More

Transcranial direct current stimulation (tDCS) has the potential to improve motor function in a range of neurological conditions, including Cerebral Palsy (CP). Although there have been many studies assessing tDCS in adult stroke, the literature regarding the efficacy of tDCS in CP is more limited. This review therefore focuses on the neurophysiological and clinical findings in children and adolescents with CP. Read More

Validating attentive locomotion training using interactive treadmill: an fNIRS study.

J Neuroeng Rehabil 2018 Dec 20;15(1):122. Epub 2018 Dec 20.

Department of Robotics Engineering, DGIST (Daegu Gyeongbuk Institute of Science and Technology), 333 Techno Jungang-daero, Daegu, 42988, Republic of Korea.

Background: Existing treadmill-based locomotion training, which has been used for gait function recovery, still has limitations, such as less attentive training. Interactive treadmills (ITMs) were developed to overcome these limitations, but it has not yet been verified that ITMs can make the user pay closer attention to walk training.

Methods: An experimental comparison between ITMs and conventional treadmills was conducted by measuring the level of the user's attention using functional near-infrared spectroscopy (fNIRS). Read More

Muscle fatigue assessment during robot-mediated movements.

J Neuroeng Rehabil 2018 Dec 17;15(1):119. Epub 2018 Dec 17.

Motor Learning, Assistive and Rehabilitation Robotics Lab, Robotics, Brain and Cognitive Sciences unit, Istituto Italiano di Tecnologia, Genoa, Italy.

Background: Several neuromuscular disorders present muscle fatigue as a typical symptom. Therefore, a reliable method of fatigue assessment may be crucial for understanding how specific disease features evolve over time and for developing effective rehabilitation strategies. Unfortunately, despite its importance, a standardized, reliable and objective method for fatigue measurement is lacking in clinical practice and this work investigates a practical solution.

Why orthotic devices could be of help in the management of Movement Disorders in the young.

J Neuroeng Rehabil 2018 Dec 14;15(1):118. Epub 2018 Dec 14.

Institute of Condensed Matter Chemistry and Technologies for Energy, National Research Council of Italy (CNR-ICMATE), via Previati 1/E, 23900, Lecco, Italy.

Background: Movement Disorders (MD) are a class of disease that impair the daily activities of patients, conditioning their sensorimotor, cognitive and behavioural capabilities. Nowadays, the general management of patients with MD is based on rehabilitation, pharmacological treatments, surgery, and traditional splints. Although some attempts have been made to devise specific orthoses for the rehabilitation of patients affected by MD, especially the younger ones, those devices have received limited attention.

On the use of approximate entropy and sample entropy with centre of pressure time-series.

J Neuroeng Rehabil 2018 Dec 12;15(1):116. Epub 2018 Dec 12.

School of Engineering, University of Warwick, Coventry, CV4 7AL, UK.

Background: Approximate entropy (ApEn) and sample entropy (SampEn) have been previously used to quantify the regularity in centre of pressure (COP) time-series in different experimental groups and/or conditions. ApEn and SampEn are very sensitive to their input parameters: m (subseries length), r (tolerance) and N (data length). Yet, the effects of changing those parameters have been scarcely investigated in the analysis of COP time-series. Read More

Evaluation of the Keeogo exoskeleton for assisting ambulatory activities in people with multiple sclerosis: an open-label, randomized, cross-over trial.

J Neuroeng Rehabil 2018 Dec 12;15(1):117. Epub 2018 Dec 12.

Department of Physical Medicine and Rehabilitation, Harvard Medical School, Spaulding Rehabilitation Hospital, Charlestown, MA, USA.

Background: Although physical activity and exercise is known to benefit people with multiple sclerosis (MS), the ability of these individuals to participate in such interventions is difficult due to the mobility impairments caused by the disease. Keeogo is a lower-extremity powered exoskeleton that may be a potential solution for enabling people with MS to benefit from physical activity and exercise.

Methods: An open-label, randomized, cross-over trial was used to examine the immediate performance effects when using the device, and the potential benefits of using the device in a home setting for 2 weeks. Read More

Generalizing remotely supervised transcranial direct current stimulation (tDCS): feasibility and benefit in Parkinson's disease.

J Neuroeng Rehabil 2018 Dec 7;15(1):114. Epub 2018 Dec 7.

New York University Langone Health, New York, USA.

Background: Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that has been shown to improve common symptoms of neurological disorders like depressed mood, fatigue, motor deficits and cognitive dysfunction. tDCS requires daily treatment sessions in order to be effective. We developed a remotely supervised tDCS (RS-tDCS) protocol for participants with multiple sclerosis (MS) to increase accessibility of tDCS, reducing clinician, patient, and caregiver burden.

Stochastic resonance stimulation improves balance in children with cerebral palsy: a case control study.

J Neuroeng Rehabil 2018 Dec 10;15(1):115. Epub 2018 Dec 10.

Department of Kinesiology, University of Delaware, 540 S. College Ave, Newark, DE, 19713, USA.

Background: Stochastic Resonance (SR) Stimulation has been used to enhance balance in populations with sensory deficits by improving the detection and transmission of afferent information. Despite the potential promise of SR in improving postural control, its use in individuals with cerebral palsy (CP) is novel. The objective of this study was to investigate the immediate effects of electrical SR stimulation when applied in the ankle muscles and ligaments on postural stability in children with CP and their typically developing (TD) peers.

Virtual reality experiences, embodiment, videogames and their dimensions in neurorehabilitation.

J Neuroeng Rehabil 2018 Nov 26;15(1):113. Epub 2018 Nov 26.

MindMaze SA, Lausanne, Switzerland.

Background: In the context of stroke rehabilitation, new training approaches mediated by virtual reality and videogames are usually discussed and evaluated together in reviews and meta-analyses. This represents a serious confounding factor that is leading to misleading, inconclusive outcomes in the interest of validating these new solutions.

Main Body: Extending existing definitions of virtual reality, in this paper I put forward the concept of virtual reality experience (VRE), generated by virtual reality systems (VRS; i. Read More

Questionnaire results of user experiences with wearable exoskeletons and their preferences for sensory feedback.

J Neuroeng Rehabil 2018 Nov 23;15(1):112. Epub 2018 Nov 23.

Biomechanical Engineering, University of Twente, Drienerlolaan 5, Enschede, 7522 NB, the Netherlands.

Background: Wearable exoskeletons can be a powerful tool for the facilitation of ambulation of complete Spinal Cord Injury (SCI) subjects, which has several psychological and physical advantages. However, exoskeleton control is difficult for this group of users and requires a long period of training. People with SCI not only lack the motor control, but also miss the sensory information from below the level of the lesion, which is for example very important in their perception of body posture and makes balancing with an exoskeleton difficult.

Experimental comparisons of passive and powered ankle-foot orthoses in individuals with limb reconstruction.

J Neuroeng Rehabil 2018 Nov 21;15(1):111. Epub 2018 Nov 21.

Center for the Intrepid, Department of Rehabilitation Medicine, Brooke Army Medical Center, JBSA Ft, Sam Houston, TX, USA.

Background: Ankle-foot orthoses (AFO) are commonly prescribed to provide functional assistance for patients with lower limb injuries or weakness. Their passive mechanical elements can provide some energy return to improve walking ability, but cannot restore plantar flexor push-off. Powered AFOs provide an assistive torque about the ankle to address the limitations of passive devices, but current designs have yet to be implemented on a large scale clinically. Read More

Regenerative peripheral nerve interfaces for real-time, proportional control of a Neuroprosthetic hand.

J Neuroeng Rehabil 2018 Nov 20;15(1):108. Epub 2018 Nov 20.

University of Michigan Department of Surgery, Section of Plastic Surgery, 570 MSRB II Level A, 1150 W. Medical Center Drive, Ann Arbor, MI, 48109-5456, USA.

Introduction: Regenerative peripheral nerve interfaces (RPNIs) are biological constructs which amplify neural signals and have shown long-term stability in rat models. Real-time control of a neuroprosthesis in rat models has not yet been demonstrated. The purpose of this study was to: a) design and validate a system for translating electromyography (EMG) signals from an RPNI in a rat model into real-time control of a neuroprosthetic hand, and; b) use the system to demonstrate RPNI proportional neuroprosthesis control.

Transcranial direct current stimulation (tDCS) for upper limb rehabilitation after stroke: future directions.

J Neuroeng Rehabil 2018 Nov 15;15(1):106. Epub 2018 Nov 15.

Department of Public Health, Dresden Medical School, Technical University Dresden, Fetscherstr. 74, 01307, Dresden, Germany.

Transcranial Direct Current Stimulation (tDCS) is a potentially useful tool to improve upper limb rehabilitation outcomes after stroke, although its effects in this regard have shown to be limited so far. Additional increases in effectiveness of tDCS in upper limb rehabilitation after stroke may for example be achieved by (1) applying a more focal stimulation approach like high definition tDCS (HD-tDCS), (2) involving functional imaging techniques during stimulation to identify target areas more exactly, (3) applying tDCS during Electroencephalography (EEG) (EEG-tDCS), (4) focusing on an effective upper limb rehabilitation strategy as an effective base treatment after stroke. Perhaps going even beyond the application of tDCS and applying alternative stimulation techniques such as transcranial Alternating Current Stimulation (tACS) or transcranial Random Noise Stimulation (tRNS) will further increase effectiveness of upper limb rehabilitation after stroke.

Kinect-based assessment of proximal arm non-use after a stroke.

J Neuroeng Rehabil 2018 Nov 14;15(1):104. Epub 2018 Nov 14.

Euromov, University of Montpellier, Montpellier, France.

Background: After a stroke, during seated reaching with their paretic upper limb, many patients spontaneously replace the use of their arm by trunk compensation movements, even though they are able to use their arm when forced to do so. We previously quantified this proximal arm non-use (PANU) with a motion capture system (Zebris, CMS20s). The aim of this study was to validate a low-cost Microsoft Kinect-based system against the CMS20s reference system to diagnose PANU. Read More

Toledo Physiotherapy Research Group (GIFTO), Nursing and Physiotherapy School, Castilla La Mancha University, 45071, Toledo, Spain.

Background: High-frequency alternating currents of greater than 1 kHz applied on peripheral nerves has been used in animal studies to produce a motor nerve block. It has been evidenced that frequencies higher than 5 kHz are necessary to produce a complete peripheral nerve block in primates, whose nerve thickness is more similar to humans. The aim of the study was to determine the effect on muscle strength after the application of a high-frequency stimulation at 5 and 10 kHz compared to sham stimulation in healthy volunteers.

Spinal Cord Injury Center, Balgrist University Hospital, Forchstrasse 340, CH-8008, Zürich, Switzerland.

Background: Body weight support (BWS) is often provided to incomplete spinal cord injury (iSCI) patients during rehabilitation to enable gait training before full weight-bearing is recovered. Emerging robotic devices enable BWS during overground walking, increasing task-specificity of the locomotor training. However, in contrast to a treadmill setting, there is little information on how unloading is integrated into overground locomotion. Read More
