Compromised Brain Activity With Age During a Game-Like Dynamic Balance Task: Single- vs. Dual-Task Performance.

Front Aging Neurosci 2021 5;13:657308. Epub 2021 Jul 5.

Neuromotor Rehabilitation Research Group, Department of Rehabilitation Sciences, KU Leuven, Leuven, Belgium.

Postural control and cognition are affected by aging. We investigated whether cognitive distraction influenced neural activity differently in young and older adults during a game-like mediolateral weight-shifting task with a personalized task load. Seventeen healthy young and 17 older adults performed a balance game, involving hitting virtual wasps, serial subtractions and a combination of both (dual-task). Read More

Microstimulation of the Premotor Cortex of the Cat Produces Phase-Dependent Changes in Locomotor Activity.

Cereb Cortex 2021 Jul 21. Epub 2021 Jul 21.

Département de Neurosciences, Centre Interdisciplinaire de Recherche sur le Cerveau et l'Apprentissage (CIRCA) Groupe de recherche sur le système nerveux central (GRSNC), Université de Montréal, Québec H3C 3J7, Canada.

To determine the functional organization of premotor areas in the cat pericruciate cortex we applied intracortical microstimulation (ICMS) within multiple cytoarchitectonically identified subregions of areas 4 and 6 in the awake cat, both at rest and during treadmill walking. ICMS in most premotor areas evoked clear twitch responses in the limbs and/or head at rest. During locomotion, these same areas produced phase-dependent modifications of muscle activity. Read More

Action Observation and Motor Imagery Improve Dual Task in Parkinson's Disease: A Clinical/fMRI Study.

Mov Disord 2021 Jul 19. Epub 2021 Jul 19.

Neuroimaging Research Unit, Division of Neuroscience, IRCCS San Raffaele Scientific Institute, Milan, Italy.

Background: Action observation training and motor imagery may improve motor learning in Parkinson's disease (PD).

Objectives: The objectives of this study were to assess mobility and balance (performing motor and dual tasks) and brain functional reorganization following 6 weeks of action observation training and motor imagery associated with dual-task gait/balance exercises in PD patients with postural instability and gait disorders relative to dual-task training alone.

Methods: Twenty-five PD-postural instability and gait disorder patients were randomized into 2 groups: the DUAL-TASK+AOT-MI group performed a 6-week gait/balance training consisting of action observation training-motor imagery combined with practicing the observed-imagined exercises; the DUAL-TASK group performed the same exercises combined with watching landscape videos.

Development and Functional Testing of An Unloading Concept for Knee Osteoarthritis Patients: A Pilot Study.

J Biomech Eng 2021 Jul 21. Epub 2021 Jul 21.

Aalborg, Denmark.

This paper presents a knee brace design that applies an extension moment to unload the muscles in stance phase during gait, and thereby the knee, as alternative to conventional valgus braces for knee osteoarthritis patients. The concept was tested on one healthy subject during normal gait with a prototype, which was designed to activate and deactivate in order to apply the extension moment in the stance phase only and hereby avoid any interference during the swing phase. Electromyography measurements and musculoskeletal models were used to evaluate the brace effects on muscle activation and knee compressive forces respectively. Read More

Gait Posture 2021 Jul 16;89:126-131. Epub 2021 Jul 16.

Gait Laboratory, Central Remedial Clinic, Vernon Ave, Dublin 3, Ireland. Electronic address:

Background: Increased terminal swing knee flexion (TSKF) impacts on step length, walking efficiency and may lead to knee flexion in stance in cerebral palsy (CP). Surgical lengthening of the hamstrings is often used to address this issue, but outcomes are inconsistent. There is an established association between TSKF and functional shortening or reduced lengthening velocity of the hamstrings. Read More

Protocol for Testing Yoga to Reduce Post-Lumbar Spine Surgery Pain: A Methodology Article.

Int J Yoga Therap 2021 Jul 19. Epub 2021 Jul 19.

Department of Physical Therapy and Rehabilitation Science, School of Health Professions, University of Kansas Medical Center, Kansas City.

Can Task Specificity Impact tDCS-Linked to Dual Task Training Gains in Parkinson's Disease? A Protocol for a Randomized Controlled Trial.

Front Aging Neurosci 2021 1;13:684689. Epub 2021 Jul 1.

Laboratory of Intervention and Analysis of Movement, Department of Physiotherapy, Federal University of Rio Grande do Norte, Campus Universitário, Natal, Brazil.

Patients with Parkinson's disease (PD) have difficulties while performing dual-task activities, a condition present in everyday life. It is possible that strategies such as transcranial Direct Current Stimulation (tDCS) can be associated with motor training enriched with dual-task training to improve the performance of two concurrent tasks. Currently, it is unclear whether specific tasks and clinical conditions of PD patients have different results after the intervention. Read More

Older Compared With Younger Adults Performed 467 Fewer Sit-to-Stand Trials, Accompanied by Small Changes in Muscle Activation and Voluntary Force.

Front Aging Neurosci 2021 21;13:679282. Epub 2021 Jun 21.

Department of Human Movement Sciences, University Medical Center Groningen, University of Groningen, Groningen, Netherlands.

Repetitive sit-to-stand (rSTS) is a fatigue perturbation model to examine the age-effects on adaptability in posture and gait, yet the age-effects on muscle activation during rSTS are unclear. We examined the effects of age and exhaustive rSTS on muscle activation magnitude, onset, and duration during ascent and descent phases of the STS task. Healthy older ( = 12) and younger ( = 11) adults performed rSTS, at a controlled frequency dictated by a metronome (2 s for cycle), to failure or for 30 min. Read More

Decoding of Motor Coordination Imagery Involving the Lower Limbs by the EEG-Based Brain Network.

Comput Intell Neurosci 2021 23;2021:5565824. Epub 2021 Jun 23.

Brain Cognition and Brain-computer Intelligence Integration Group, Kunming University of Science and Technology, Kunming 650500, China.

Compared with the efficacy of traditional physical therapy, a new therapy utilizing motor imagery can induce brain plasticity and allows partial recovery of motor ability in patients with hemiplegia after stroke. Here, we proposed an updated paradigm utilizing motor coordination imagery involving the lower limbs (normal gait imagery and hemiplegic gait imagery after stroke) and decoded such imagery via an electroencephalogram- (EEG-) based brain network. Thirty subjects were recruited to collect EEGs during motor coordination imagery involving the lower limbs. Read More

Wide-range Motion Recognition through Insole Sensor using Multi-walled Carbon Nanotubes and Polydimethylsiloxane Composites.

IEEE J Biomed Health Inform 2021 Jul 13;PP. Epub 2021 Jul 13.

High linearity/sensitivity and a wide dynamic sensing range are the most desirable features for pressure sensors to accurately detect and respond to external pressure stimuli. Even though a number of recent studies have demonstrated a low-cost pressure sensing device for a smart insole system by using scalable and deformable conductive materials, they still lack stretchability and desirable properties such as high sensitivity, hysteresis, linearity, and fast response time to obtain accurate and reliable data. To resolve this issue, a flexible and stretchable piezoresistive pressure sensor with high linear response over a wide pressure range is developed and integrated in a wearable insole system.

Eur Rev Aging Phys Act 2021 Jul 12;18(1):16. Epub 2021 Jul 12.

Laboratory of the Metabolic Adaptations to Exercise under Physiological and Pathological Conditions (AME2P - EA 3533), University Clermont Auvergne, Clermont-Ferrand, France.

Background: Mild cognitive impairment (MCI) affects 10-20% of the individuals over the age of 65; this proportion being higher in the institutional care facilities than within a general population.

Aim: To assess whether dual-task cost in the individuals affected by MCI depends exclusively on gait, or possibly some other functional capacity components might also come into play, as compared to the healthy controls also remaining in the institutional care.

Methods: The study was conducted in five nursing facilities, involving 88 subjects in total, i. Read More
