Abstract Background The lower-extremity motor coordination test (LEMOCOT) is a performance-based measure used to assess motor coordination deficits after stroke. We aimed to automatically quantify performance on the LEMOCOT and to extract additional performance parameters based on error analysis in persons with stroke (PwS) and healthy controls. We also aimed to explore whether these parameters provide additional information regarding motor control deficit that is not captured by the traditional LEMOCOT score. In addition, the associations between the LEMOCOT score, parameters of error and performance-based measures of lower-extremity impairment and gait were tested. Methods Twenty PwS (age: 62 ± 11.8 years, time after stroke onset: 84 ± 83 days; lower extremity Fugl-Meyer: 30.2 ± 3.7) and 20 healthy controls (age: 42 ± 15.8 years) participated in this cross-sectional exploratory study. Participants were instructed to move their big toe as fast and accurately as possible between targets marked on an electronic mat equipped with force sensors (Zebris FDM-T, 60 Hz). We extracted the contact surface area of each touch, from which the endpoint location, the center of pressure (COP), and the distance between them were computed. In addition, the absolute and variable error were calculated. Results PwS touched the targets with greater foot surface and demonstrated a greater distance between the endpoint location and the location of the COP. After controlling for the number of in-target touches, greater absolute and variable errors of the endpoint were observed in the paretic leg than in the non-paretic leg and the legs of controls. Also, the COP variable error differentiated between the paretic, non-paretic, and control legs and this parameter was independent of in-target counts. Negative correlations with moderate effect size were found between the Fugl Meyer assessment and the error parameters. Conclusions PwS demonstrated lower performance in all outcome measures than did controls. Several parameters of error indicated differences between legs (paretic leg, non-paretic leg and controls) and were independent of in-target touch counts, suggesting they may reflect motor deficits that are not identified by the traditional LEMOCOT score.

Objective: To establish any changes up to the second postoperative month in pain, disability, performance, kinesiophobia, and lower extremity motor coordination of patients operated on for lumbar disc hernia. Methods: Forty-five patients with lumbar disc hernia were included in the study preoperatively, and were followed up until the second postoperative month. Pain and disability, walking and stair-climbing performances, and kinesiophobia were measured; and motor coordination tests were practiced with the Lower Extremity MOtor COordination Test (LEMOCOT). Results: The worst scores of pain, disability, performance, kinesiophobia, and LEMOCOT measurements were in the preoperative period; while the best ones were observed in the 2 months following the surgery. Conclusion: The measurements of pain, disability, performance, kinesiophobia, and lower extremity coordination usually performed in the cases operated on with a diagnosis of lumbar disc hernia are significantly affected from the initial period until the second postoperative month.

Objective. To determine if patients with traumatic brain injury (TBI) and motor deficits show differences in functional activation maps during repetitive hand movements relative to healthy controls. Are there predictors for motor outcome in the functional maps of these patients? Methods. In an exploratory cross-sectional study, functional magnetic resonance imaging (fMRI) was used to study the blood-oxygenation-level-dependent (BOLD) response in cortical motor areas of 34 patients suffering from moderate motor deficits after TBI as they performed unilateral fist-clenching motions. Twelve of these patients with unilateral motor deficits were studied 3 months after TBI and a 2nd time approximately 4 months later. Results. Compared to age-matched, healthy controls performing the same task, TBI patients showed diminished fMRI-signal change in the primary sensorimotor cortex contralateral to the moving hand (cSM1), the contralateral dorsal premotor cortex, and bilaterally in the supplementary motor areas (SMAs). Clinical impairment and the magnitude of the fMRI-signal change in cSM1 and SMA were negatively correlated. Patients with poor and good motor recovery showed comparable motor impairment at baseline. Only patients who evolved to “poor clinical outcome” had decreased fMRI-signal change in the cSM1 during baseline. Conclusions. These observations raise the hypothesis that the magnitude of the fMRI-signal change in the cSM1 region could have prognostic value in the evaluation of patients with TBI.

Abstract Introduction. Motor coordination is a basic motor ability necessary for daily life, which also allows athletes to win a sports rivalry and patients to assess their recovery progress after therapy and rehabilitation. The aim of the present study was to assess the reliability of a new lower-extremity rate of movements test and testing apparatus. Material and methods. The study sample consisted of 92 students aged 19.21 ± 3.55 years, with body height of 171.2 ± 15.11 cm and body mass of 66.01 ± 12.32 kg. The study used a test-retest method. Results. The correlation between the test and the retest was rs = 0.79 (p < 0.001) for the right leg, and rs = 0.78 (p < 0.001) for the left leg. In both cases a positive linear correlation was observed (rs > 0). Conclusions. The results of the study showed that the new rate of movements electronic testing apparatus was highly valid and reliable. Its technical possibilities eliminate errors that might have occurred earlier during manual counting of the performed cycles of movements.

Additional Information

Instrumented assessments of quiet-stance postural control typically involve recording and analyzing of body sway signal, most often the center of pressure (CoP) movement. It has been recently suggested that transient characteristics of body sway may offer additional information regarding postural control. In this study, we explored the relationship between whole-trial estimates of body sway (CoP velocity, amplitude, and frequency) and corresponding transient behavior indexes, as well as the effects of leg preference. A total of 705 healthy young athletes performed 30 s single-leg body sway trials for both legs. It was found that the transient characteristics of the body sway (expressed as relative differences between individual time intervals within the trial) are in negligible or weak correlation (r ≤ 0.26) with the corresponding variables, averaged across the whole trial. All CoP variables showed transient characteristics, reflected in statistically significant decrease (CoP velocity and amplitude) or increase (CoP frequency) throughout the trial. The preferred leg showed smaller body sway; however, the effect sizes were very small. Moreover, differences between the legs were also noted in terms of transient characteristics of body sway. In particular, the preferred leg showed earlier reduction in anterior–posterior body sway and larger reduction in medial–lateral body sway. Further studies should focus on examining the clinical utility of indexes of transient behavior of body sway, for instance, their sensitivity to aging-related changes and risk of falling.

ABSTRACT Context: A relationship between a positive history of sport-related concussion (SRC) and lower extremity (LE) injury has been well established in the literature. Objective: The purpose of this study was to determine if biomechanical differences exist during a double limb jump landing (DLJ) between athletes who had been released for return to play after SRC and healthy matched controls (Healthy). Design: Cross-Sectional Study Setting: Health system-based Outpatient Sports Medicine Center Participants: 21 participants (16.33±12.7 days out from being released to return to sport after SRC) (age: 15.38±1.77; height: 169.23±8.59; mass: 63.43±7.39) were compared to 21 age, sex, activity-matched healthy controls (age: 15.36±1.73; height: 169.92±11.1; mass: 65.62±12.08). No significant differences existed between groups for descriptive data. Main Outcome Measure(s): Biomechanical performance during DLJ was assessed using Motion Capture System and force plates. The average of five consecutive trials was used to calculate lower extremity joint kinetic and kinematics. Variables of interest included internal knee extension moment, internal varus moment, and total sagittal plane knee displacement for both the dominant and non-dominant limbs. Independent t-tests were performed to examine the differences between SRC and Healthy groups for variables of interest. Results: The SRC group demonstrated greater internal knee extension moments on their dominant (KEDomDiff=–.028±.009; p=.003) and non-dominant (KENonDomDiff=–.018±.007, p=.019) limbs. The SRC group also demonstrated greater internal varus moments on their dominant (VDomDiff=.012±.004, p=.005) and non-dominant (VNonDomDiff=.010±.003, p=.005) limbs. For sagittal plane knee displacement, the SRC group demonstrated less knee flexion displacement on their dominant (DispDomDiff=–12.56±4.67, p=.011) but not their non-dominant limb (DispNonDomDiff=–8.30±4.91, p=.099). Conclusions: Athletes who have been released for return to sport after SRC land in greater knee valgus compared to healthy matched controls.

Background. Stroke is the most common cause of long-term disability in the United States (US). Assisted Cycling Therapy (ACT) at cadences of about 80 rpm has been associated with improvements in motor and clinical function in other clinical populations. The acute effects of ACT on motor function of persons with stroke have not been investigated. Objectives. The primary purpose of this cross-over trial was to compare the effects of ACT, voluntary cycling (VC), and no cycling (NC) on upper (Box and Blocks Test) and lower extremity motor function (Lower Extremity Motor Coordination Test) in adults with chronic stroke (age: 60 ± 16 years; months since stroke: 96 ± 85). The secondary purpose was to examine average cycling cadence and ratings of perceived exertion as predictors of change in motor function following the exercise session. Methods. Twenty-two participants (female = 6, male = 16) completed one 20-min session each of ACT (mean cadence = 79.5 rpm, VC (mean cadence = 51.5 rpm), and NC on separate days in quasi-counterbalanced fashion). Results. Main effects of intervention did not differ between ACT and VC. Within-intervention analyses revealed significant (p < 0.05) pre- to posttest changes in all outcome measures for ACT but only in the Lower Extremity Motor Coordination Test on the non-paretic side for VC. Trend analyses revealed a positive relationship between average ACT cadences and improvements in upper and lower extremity motor function (p < 0.05). A positive relationship between average VC cadences and lower extremity function was also revealed (p < 0.05). Conclusion. ACT and VC produced similar acute improvements in paretic and non-paretic lower extremity motor function whereas changes in upper extremity motor function were more limited. Faster cycling cadences seem to be associated with greater acute effects.

IntroductionSchizophrenia (SZ) patients present subtle motor deficits known as Neurological Soft Signs (NSS). Those deficits encompass impairments of motor coordination, sequencing of complex motor acts and sensory integration. It has been shown that SZ patients present also deficits of higher motor functions as implicit motor learning. Growing number of studies indicate that both NSS and implicit motor learning deficits are associated with impairments of common cortico-cerebellar pathways, however relationship between these two deficits has not been evaluated yet.ObjectivesTo assess NSS and implicit motor learning in SZ patients.AimsTo evaluate associations between NSS and implicit motor learning scores in SZ patients.MethodsTwenty schizophrenia patients and 20 healthy controls were examined. Patients were under olanzapine, clozapine or quetiapine treatment. NSS were assessed with Neurological Evaluation Scale (NES). Implicit motor learning were assessed with a use of Serial Reaction Time Task.ResultsSZ patients presented statistically higher NSS scores than healthy controls (P < 0.001) and presented no signs of implicit motor learning. There was statistically significant negative correlation between implicit motor learning score and total score of neurological soft signs (r = −0.44), sequence of motor acts subscore (r = −0.54) and sensory integration subscore (r = −0.47) in SZ patients group (P < 0.05).ConclusionsThere is association between implicit motor learning deficits and neurological soft signs in SZ patients.Disclosure of interestThe authors have not supplied their declaration of competing interest.
