The direct effect of variable X3 on Y = 0,378. The direct effect of variable X1 on X3 = 0,706. The direct effect of variable X2 on X3 = 0,297. The indirect effect of variable X1 on Y through X3 = 0,706 x 0,378 = 0,267. The indirect effect of variable X2 on Y through X3 = 0,297 x 0,378 = 0,113.

Study to Find the Effect in Combined Protocol of Aquatic Therapy and Play Therapy in Attention Deficit Hyperactive Disorder in School Going Children from 7 – 10 Years to Improve the Quality of Life

The Objective of the Study: The aim of this study is to see the effect of combined protocol on aquatic and play therapy for children with ADHD based on inattention, hyperactivity, impulsivity, and anxiety. Background: Attention Deficit Hyperactivity Disorder (ADHD) is a severe threat to public health that affects a huge number of children and typically continues into adulthood. It is characterized by persistent lack of attention, hyperactivity, and impulsivity that impairs growth and performance. Children with ADHD are usually treated with a combination of pharmacological and non - pharmacological treatments, including academic, psycho-social, and behavioral aid, as well as aquatic therapy and play therapy. Aquatic therapy and play therapy, on the other hand, are ways in which the kid is provided the chance to undergo growth in the most optimum conditions. The goal of this study is to see how effective aquatic therapy and play therapy are in raising the standard of living of children aged 7 to 10 who have attention deficit hyperactivity disorder. Methods: The design of the present study is quasi-experimental. Tools used for the study: Data were collected through Conner’s parent’s rating scale, pediatric balance scale, and hand-eye coordination scale as pre and post-test and the treatment group received aquatic therapy and play therapy for eight sessions. Results: Conner's parent rating scale, pediatric balance scale, and hand-eye coordination test were used to compare before and after results. Conner's parent rating scale had a difference between the means of 21, a standard deviation of 4.79, and a paired-t-test value of 23.98. The pediatric balance scale's mean difference was 19, the standard deviation was 3.82, and the paired-t significance level was 27.20. The average difference in the hand-eye coordination test was 11, with a standard deviation of 1.67 and a paired-t-test score of 36.02. Conclusion: According to the findings, using aquatic therapy and play therapy to help children with ADHD pay close attention, reduce hyperactivity, and manage impulsive behavior was beneficial. Play therapy and aquatic therapy are also good ways to have some exercise. This increased energy utilization causes them to be less impulsive and hyperactive over the rest of the day.

Construct Validity of the Upper-Limb Interlimb Coordination Test in Stroke

Background Coordination impairments are under-evaluated in patients with stroke due to the lack of validated assessments resulting in an unclear relationship between coordination deficits and functional limitations. Objective Determine the construct validity of the new clinical upper-limb (UL) Interlimb Coordination test (ILC2) in individuals with chronic stroke. Methods Thirteen individuals with stroke, ≥40 years, with ≥30° isolated supination of the more-affected (MAff) arm, who could understand instructions and 13 healthy controls of similar age participated in a cross-sectional study. Participants performed synchronous bilateral anti-phase forearm rotations for 10 seconds in 4 conditions: self-paced internally-paced (IP1), fast internally-paced (IP2), slow externally-paced (EP1), and fast externally-paced (EP2). Primary (continuous relative phase-CRP, cross-correlation, lag) and secondary outcome measures (UL and trunk kinematics) were compared between groups. Results Participants with stroke made slower UL movements than controls in all conditions, except EP1. Cross-correlation coefficients were lower (i.e., closer to 0) in stroke in IP1, but CRP and lag were similar between groups. In IP1 and matched-speed conditions (IP1 for healthy and IP2 for stroke), stroke participants used compensatory trunk and shoulder movements. The synchronicity sub-scale and total scores of ILC2 were related to temporal coordination in IP2. Interlimb Coordination test total score was related to greater shoulder rotation of the MAff arm. Interlimb Coordination test scores were not related to clinical scores. Conclusion Interlimb Coordination test is a valid clinical measure that may be used to objectively assess UL interlimb coordination in individuals with chronic stroke. Further reliability testing is needed to determine the clinical utility of the scale.

Insights into motor performance deficits after stroke: an automated and refined analysis of the lower-extremity motor coordination test (LEMOCOT)

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.

Wall Drop Punt Kick & Catch: Contributions towards the creation of a new gross manipulative coordination test

This study aimed to search for age and sex differences on a manipulative eye-segmental (hand and foot) coordination task. It represents the first step towards a possible creation of a manipulative eye-hand and eye-foot coordination test that may be used in motor competence test batteries. One hundred and sixty-eight children (85 boys and 83 girls), with a mean age of 12.79 years old (±1.56) were assessed. Subjects had 30 seconds to achieve as many ball impacts as possible on a front wall (two meters apart), following a drop punt kick, rebound on the wall and catch sequence. Compared to girls’, boys’ performance was significantly better (p < .001) on each studied age (10, 11, 13 and 14), with large effect sizes (all four Cohen’s d values over 1.30). Besides, 10 and 11 years-old subjects’ performance, both in boys and in girls, was significantly lower than their 13 and 14 years-old subjects’ counterparts (p < .001, except for the comparison between 13 and 14 years-old subjects, on girls, where p < .01). All related effect sizes were large (all Cohen’s d values over 1.03). Results confirm literature, as boys’ performance on this manipulative task was significantly better than girls’ one. The results seem to be promising about the possible use of the task in question as an eye-hand and eye-foot coordination test in future. Further research needs to be performed, namely aiming its validation (testing its reliability and concurrent validity).

Evaluation of Explicit Motor Timing Ability in Young Tennis Players

A crucial ability for athletes playing sports that involve coincidence timing actions is the motor timing ability. The efficiency of perceptual and motor processes underlying the motor timing ability has been related to the motor experience gained in interceptive sports, such as tennis. In the present study, the motor timing ability in young tennis players (TP) and age-matched control participants (CTRL) was compared by means of a synchronization paradigm. Participants were asked to perform finger-opposition movements in synch to a metronome beating 0.5 and 2 Hz in (1) a bimanual coordination test, which compared the performance of the dominant hand with that of the contralateral hand, and (2) a movement lateralization test, which compared the motor performance of the dominant hand during single-hand and bimanual tasks (BTs). The motor performance was evaluated through movement strategy [defined by touch duration (TD), inter-tapping interval (ITI), and movement frequency] and movement accuracy (temporal accuracy defined by the synchronization error and spatial accuracy defined by the percentage of correct touches—%CORR_SEQ). Results showed that motor expertise significantly influences movement strategy in the bimanual coordination test; TD of TP was significantly higher than those of CTRL, specifically at 0.5 Hz. Furthermore, overall ITI values of TP were lower than those of CTRL. Lastly, in the movement lateralization test, the %CORR_SEQ executed with the right dominant hand by TP in the BT was significantly higher than those of CTRL. A discussion about the role of motor expertise in the timing ability and the related neurophysiological adaptations is provided.

Reliability of a Reactive Agility Test for Youth Volleyball Players

Introduction. This was a cross-sectional study aiming to test the reliability of a new reactive agility test designed for youth volleyball players to improve both reaction time and hand-eye coordination. Material and methods. Twenty-four youth volleyball athletes (15 girls and 9 boys) were recruited to participate in this study (age: 11.58 ± 2.20 years old). This study used a FitLight Trainer (FITLIGHT Sport Corp., Ontario, Canada), a wireless system using interconnected light-powered sensors, to measure reaction time and hand-eye coordination. The subjects performed the hand-eye coordination test twice, exactly one week apart, for 30 seconds, with three trials performed for each test. Repeated measures ANOVA was used to test the variation of the six trials performed during the two sessions. Results. The analysis comparing the sessions revealed significantly longer reaction time in session 1 than in session 2 (mean difference: 47.85 [95% CI: 10.86 to 84.84]; p < 0.012; ES = 0.128). Across the different trials, the greatest single ICC measure (ICC = 0.645) and average ICC measure (ICC = 0.784) were achieved in trial 3. Across the sessions, the greatest single ICC measure (ICC = 0.951) and average ICC measure (ICC = 0.863) were achieved in session 2. Conclusions. FitLight Trainer is a valid and reliable tool for developing reaction times of youth volleyball athletes.
