AIM OF THE STUDY: Sensory gating is a human higher cognitive function that serves to suppress excessive sensory information and prevent brain overactivity. To elucidate this function, a paired-pulse stimulation paradigm has been used while recording electroencephalography (EEG), and evaluated as an amplitude ratio of responses to a second stimulus (S2) over responses to the first stimulus (S1). The present study investigated the effects of the inter-stimulus interval (ISI) and inter-trial interval (ITI) on somatosensory gating using somatosensory-evoked potentials (SEPs)...

This study examined whether tactile gating induced by the descending motor command to one finger spreads out to the other fingers to which the command is not delivered and whether this gating is dependent on the target finger to which the command is delivered. The change in perceptual threshold to the digital nerve stimulation of one finger induced by tonic contraction of the first dorsal interosseous or abductor digiti minimi muscle was examined. The perceptual threshold to the digital nerve stimulation of the thumb or little finger was increased by tonic contraction of the abductor digiti minimi muscle...

AIM OF THE STUDY: The application of a noxious stimulus reduces the perception and responsiveness to other pain stimuli. This inhibition can be experimentally assessed with a method called 'counterirritation'. The question arises if counterirritation acts also on the perception and responsiveness to aversive but non-nociceptive stimuli (e.g., loud tones). Since aversive stimulation is often associated with state anxiety or state fear, we investigated in addition the modulatory effects of these emotions on counterirritation...

PURPOSE: We investigated the connectivity of neural signals from movement-related cortical areas to the primary motor area (M1) in the hemisphere contralateral to the movement side during the period of movement-related magnetic fields before movement. MATERIALS AND METHODS: Participants were 13 healthy adults, and nerual signals were recorded using magnetoencephalography. Spontaneous extension of the right wrist was performed at the participant's own pace and following a visual cue in internal (IC) and external (EC) cue tasks...

BACKGROUND: Transcranial direct current stimulation (tDCS) is widely used in motor recovery. Nevertheless, whether tDCS improves motor learning in healthy older adults is still controversial. This review aims to investigate the effectiveness of tDCS on motor learning in healthy elderly individuals. METHODS: The PubMed, Cochrane Library, Web of Science and Embase databases were initially searched from inception to December 5, 2022. The standard mean difference (SMD) with the corresponding 95% confidence intervals (CIs) were analysed via random-effect models...

AIM: This study aimed to compare the acute effects of different methods on ankle joint range of motion (ROM) in older adults. MATERIALS AND METHODS: Seventy-eight older adults were randomly divided into three groups. After the warming-up, static stretching, proprioceptive neuromuscular facilitation (PNF) contract-relax, and roller massage were applied, at the same period. Before application, immediately after, 10 and 20 min after application, ankle joint dorsiflexion ROM was measured in the weight-bearing position...

Purpose/Aim . Autistic individuals may show either hyper- or hypo- responsiveness to touch compared to non-autistic individuals. These behavioural responses depend on perceptual and evaluative mechanisms, which unfold sequentially and thus can be distinguished by exploring the timing of neural responses. In this study, we examined neural response timing to pleasant, unpleasant, and affectively neutral textures, to determine whether these perceptual versus evaluative subprocesses differ in autism and how each subprocess contributes to behavioural responses...

PURPOSE/AIM: The ability to perform routine tasks during reaching and activities of daily living (ADLs) is impaired as a result of deterioration in the postural adjustments after stroke. Trunk stability is needed to maintain balance, correct scapular position and posture while moving the upper extremity. The objective was to examine the effect of scapular exercises on the scapular stability, trunk control and ADLs. MATERIALS AND METHODS: Patients (50-85 years) with acute hemiparetic stroke were participated in this double blind randomized controlled study...

BACKGROUND: This study aimed to expand our existing information on changes in the regulation of motor movement and behaviour by investigating the effects of unilateral and bilateral lesions on the claustrum (CL). MATERIAL AND METHODS: 36 Wistar Albino adult male rats were randomly divided into six groups. An electrical lesion was created with a constant current source in the unilateral and bilateral anterior clastrum using a stereotaxic frame in rats. The lesioned groups and the control group underwent an automatic behaviour recording device such as mobilisation, freezing, eating, drinking behaviour, grooming, turning, etc...

PURPOSE: Previous studies demonstrated that providing light finger touch to a stationary object leads to reduced body sway. The focus of the current exploratory study was on the investigation of postural sway during one-leg stance when light touch is provided by the contralateral foot. METHODS: Eleven healthy young adults participated in the study. They stood on the top of the force platform with eyes open and on their dominant leg with no touch and with a touch from the contralateral foot applied to the stance leg...

AIMS: Application of muscle-tendon vibration within the frequency range of 70-120Hz has been studied as a tool to stimulate somatosensory afferents with both the goal of studying human sensorimotor control and of improving post-stroke motor performance. Specific to applications for rehabilitation, current evidence is mixed as to whether dual muscle-tendon vibration is detrimental to the performance of goal-directed upper-limb movements. The current study aimed to determine the effects of muscle-tendon vibration over the wrist flexors and extensors (dual vibration) on performance of a computer goal-directed aiming task...

PURPOSE/AIM: To investigate the relationship of pain intensity, disability level, physical activity level, and body awareness with kinesiophobia in pregnant women with low back pain (LBP). MATERIALS AND METHODS: This cross-sectional study was conducted in the obstetrics and gynaecologic clinic of a tertiary centre. Eighty-six pregnant women were included in the study. Pain intensity, disability level, physical activity, body awareness, and kinesiophobia were assessed with a Visual Analogue Scale, the Oswestry Disability Index (ODI), the International Physical Activity Questionnaire-Short Form (IPAQ-SF), the Body Awareness Questionnaire (BAQ), and the Tampa Scale for Kinesiophobia (TSK), respectively...

Individuals with Moderate Intellectual Disability (MID) have lower levels of physical activity than typically developing peers. Considering the positive effects of physical activity on health, it is vital to identify effective exercise interventions for individuals with MID in everyday environments. The aim of our study was to examine the effects of theraband exercises on muscle strength and motor development of individuals with MID. A total of 16 individuals with MID were included in the study. Participants were divided into experimental and control group by random sampling method...
