Our purpose is to present evidence that faller older adults exhibit motor behavior changes beyond the typically investigated standing and walking tasks. We showed initially that postural control alterations with more prominent differences for fallers than non-fallers seem to depend on postural demands, availability of sensory information, and tasks performed concomitantly with the balancing task. We also provided evidence that walking speed is the most consistent aspect to differentiate fallers from non-fallers. This reduction in walking speed may be a strategy to improve gait stability to avoid a fall. More recent studies have shown that fallers presented modifications in the control of the prehension movement. These changes suggest that fallers have changes in movement categories other than balancing and walking, suggesting that fallers’ difficulties are broader than previously thought. The fact that faller older adults have modifications in the control of upper and lower limbs is indicative of a change in motor behavior involving gross and fine motor behaviors. The understanding of a faller as an individual with global changes in motor behavior has important implications for fall prevention and rehabilitation programs for these individuals.","PeriodicalId":91007,"journal":{"name":"Brazilian journal of motor behavior","volume":"136 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78227885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data analysis was based on the method of fixation-aligned pupillary response averaging.\u0000RESULTS: Noise curves were around baseline (zero) values while pupil dilation curves clearly stood out from noise magnitude, in all conditions for both groups. Greater pupil dilation peak during talking on the cell phone (handheld and hands-free conditions) while driving occurred only for the novice group.\u0000CONCLUSION: Adaptation and application of the method of fixation-aligned pupillary response averaging to the car driving context succeed. Cognitive workload imposed by the dual task of talking on a cell phone increased pupil dilation for novice drivers, which may alter acquisition of visual information and impair driving behavior.","PeriodicalId":91007,"journal":{"name":"Brazilian journal of motor behavior","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77784098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, no study has examined the influence of bilateral TDCS of both M1 and how it affects corticospinal excitability, cross-activation and cross-education of muscle strength.\u0000METHOD: Twelve participants underwent three conditions in a randomized crossover design: (1) submaximal grip training and single-site unilateral-high definition-TDCS (2) submaximal grip training and bilateral anodal-high definition-TDCS, and (3) submaximal grip training and sham-high definition-TDCS. Submaximal gripping task involved a single-session of unilateral training which was squeezing the transducer at 70% of maximum voluntary isometric contraction (MVIC) grip force and performing four sets of 10 isometric contractions. Anodal-high definition-TDCS was applied for 15 min at 1.5 mA over right M1 or left and right M1s, and in a sham condition. Participants were pseudorandomized to receive either single-site or bilateral M1 stimulation with each session separated by one-week. Before and after each session, MVIC force of ipsilateral and contralateral gripping, ipsilateral stimulus-response curve, short-interval intracortical inhibition, cortical silent period, intracortical facilitation, long-interval intracortical inhibition, and cross-activation were measured.\u0000RESULTS: MVIC of the trained arm decreased by 43% (P=0.04) after training. We observed no changes in MVIC of the untrained hand and in any of the TMS measures (all P>0.05).\u0000CONCLUSION: A single session of submaximal grip training with or without anodal-high definition-TDCS produces no cross-education of maximal grip force nor does it affect the excitability of the ipsilateral M1.","PeriodicalId":91007,"journal":{"name":"Brazilian journal of motor behavior","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73586952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the sensitivity to change and the responsiveness of sitting and standing from the ground in patients with DMD.\u0000AIM: The aim was to assess the sensitivity to change and the responsiveness of lowering to/ rising from the ground, in three, six, nine, and twelve month-evaluation intervals and to define the most suitable reevaluation intervals for ambulatory patients with DMD.\u0000METHOD: This is an observational, longitudinal study. Recordings of 28 patients performing lowering to/ rising from the ground were analyzed. Sensitivity to change was assessed using effect sizes and standardized response means. Responsiveness was assessed using minimal detectable changes (MDC) and minimal clinically important differences (MCID).\u0000RESULTS: In the lowering to the ground, significant sensitivity to change was found in higher than 6 months reassessment intervals. In the rising from the ground, significant sensitivity to change was observed in higher than 9 reassessment intervals. MDC and MCID varied from 1.0 to 1.6 points and from 0.5 to 2.5 seconds when lowering to the ground and from 1.3 to 2.6 points and from 5.0 to 28.0 seconds when rising from the ground.\u0000CONCLUSION: Patients should be reassessed after nine months from the lowering to and rising from the ground. Increments of 2.0 points and/or 2.5 seconds (or higher) in the score of lowering to the ground assessment denote clinically relevant changes. Increments of 3 points (or higher) in rising from the ground assessment are clinically relevant.

Conditions included: haptic contact (dog and no-dog), vision constraint (eyes open, EO, and eyes closed, EC), and surfaces (4 heights).\u0000RESULTS: Interaction between haptic condition and vision showed that contact with the dog leash reduced root mean square (RMS) and mean sway speed (MSS). RMS showed that the highest surface had the greatest rate of sway reduction during haptic contact with EC, and an increase with EO.\u0000CONCLUSION: The dog’s movements were used as a haptic reference to aid balance when eyes were closed.

However, it is not clear how music affects the RPE, neuromuscular, and cognitive responses to exercise.\u0000AIM: To determine whether listening to preferred music during indoor endurance exercise influences RPE, neuromuscular, and cognitive responses in healthy individuals.\u0000METHOD: Thirteen healthy adults performed sessions of prolonged indoor cycling at moderate intensity while listening or not to preferred music. Reaction time, selective attention, and memory were evaluated before, during, and/or after the exercise sessions. RPE, heart rate, muscle activation, pedaling torque, and cadence were recorded during the exercises.\u0000RESULTS: RPE (P = 0.004, d = 0.40), heart rate (P = 0.048, d = 0.53) and cadence (P = 0,043; d = 0.51) were higher in the music session compared to no music. Selective attention (P = 0.233), simple reaction time (P = 0.360), working and short-term memory (P > 0.05), as well as torque (P = 0.262) and muscle activation (RMS and MDF, P > 0.05) did not differ between music and no music sessions.\u0000CONCLUSION: Indoor cycling while listening to preferred music elicited higher internal loads, which we consider a result of higher cardiovascular demand.
