Effectiveness of single leg standing up exercise for recovery of knee muscle strength and lower extremity motion function following anterior cruciate ligament reconstruction

PurposeWe investigated the effectiveness of single-leg standing exercise (SLSE) as a home-based self-exercise for the recovery of knee joint muscle strength and lower limb motor function after anterior cruciate ligament (ACL) reconstruction. MethodsIn addition to postoperative rehabilitation, 55 patients who underwent ACL repair were asked to begin SLSE as a home-based self-exercise 50 times per day using a platform elevated at 40 ​cm for 2 months, 30 ​cm at 3 months, 20 ​cm at 4 months, and 10 ​cm at 5 months (intervention group). Sixty-four patients who underwent ACL reconstruction and followed the existing rehabilitation protocol were included in the control group. Isokinetic knee extension and flexion at 60° angular velocity at 3, 8, and 10 months after surgery and lower limb motor function performance at 8 and 10 months after surgery were compared within and between the two groups. ResultsKnee extension and flexion muscle strength and lower-extremity motor function recovered over time in both groups. There were no significant differences in knee extension and flexion muscle strength between the two groups at 3 months after surgery. However, knee extension strength, flexion strength, and triple hop test (THT) results were significantly higher in the intervention group (p ​< ​0.01) 8 months after surgery. In addition, knee flexion strength and THT were significantly higher in the intervention group (p ​< ​0.01) 10 months after surgery. ConclusionsThe results of this study suggest that SLSE can be an effective exercise for recovering knee joint muscle strength and lower limb motor function.

The interplay between tauopathy and aging through interruption of UPR/Nrf2/autophagy crosstalk in the Alzheimer’s disease transgenic experimental models

Purpose Alzheimer’s disease (AD) is the most common form of tauopathy that usually occursduring aging and unfolded protein response (UPR), oxidative stress and autophagy play a crucialrole in tauopathy-induced neurotoxicity. The aim of this study was to investigate the effects oftauopathy on normal brain aging in a Drosophila model of AD. Method We investigated the interplay between aging (10, 20, 30, and 40 days) and human tauR406W (htau)-induced cell stress in transgenic fruit flies. Results Tauopathy caused significant defects in eye morphology, a decrease in motor function and olfactory memory performance (after 20 days), and an increase in ethanol sensitivity (after 30 days). Our results showed a significant increase in UPR (GRP78 and ATF4), redox signalling (p-Nrf2, total GSH, total SH, lipid peroxidation, and antioxidant activity), and regulatory associated protein of mTOR complex 1 (p-Raptor) activity in the control group after 40 days, while the tauopathy model flies showed an advanced increase in the above markers at 20 days of age. Interestingly, only the control flies showed reduced autophagy by a significant decrease in the autophagosome formation protein (dATG1)/p-Raptor ratio at 40 days of age. Our results were also confirmed by bioinformatic analysis of microarray data from tauPS19 transgenic mice (3, 6, 9, and 12 months), in which tauopathy increased expression of heme oxygenase 1, and glutamate-cysteine ligase catalytic subunit and promote aging in transgenic animals. Conclusions Overall, we suggest that the neuropathological effects of tau aggregates may be accelerated brain aging, where redox signaling and autophagy efficacy play an important role.

Effect of psychostimulant medications on static balance performance in adults with attention deficit hyperactivity disorder: Within-subjects repeated-measure study

ObjectiveThis study examined the effect of psychostimulant medications nPS) on balance and functional motor performance in adults with attention-deficit/hyperactivity disorder (ADHD). MethodsParticipants completed two sessions (off-medication and on-medication) in a within-subjects repeated-measure study design. There was a minimum of seven days between the two sessions. During both sessions, participants stood for 30 s per condition on a force platform. The conditions were: feet-apart with 1) eyes-open and 2) eyes-closed; feet-together with 3) eyes-open and 4) eyes-closed. Participants performed three trials of timed up and go (TUG) and lateral step-up test (LSUT) during both sessions. Outcome measures were sway area (SA [cm2]), average sway velocity (SV [cm/s]), TUG average time (s), and average number of LSUT repetitions. Data were analyzed using multivariate repeated measures analysis of variance and paired t-tests for examining PS effects on balance (SA and SV) and functional motor performance (TUG and LSUT), respectively. ResultsThe sample included 45 adults (35 females; mean age = 28.4 ± 6.3 years). The repeated-measures MANOVA indicated that PS was associated with better SA [F(1,44) = 9.6; p = 0.003;ηp2 = 0.18] but not with SV [F(1,44) = 1.0; p = 0.319;ηp2 = 0.02]. PS was associated with significantly better SA with decreasing base-of-support [F(1,44) = 9.9; p = 0.003;ηp2 = 0.18]. Additionally, PS use was associated with better TUG [t(1,44) = 2.65; p = 0.014;Cohen's d = 0.39] but not LSUT performances [t(1,44) = −0.68; p = 0.499;Cohen's d = −0.10]. ConclusionsPS was associated with better SA and TUG in adults with ADHD. Further studies are needed to investigate the effects of PS on balance performance using rigorous designs in this population. ImpactHealthcare providers should screen for PS status and balance when treating adults with ADHD to enhance safe motor performance.

Exploration of the relationship between functional motor and communication performance levels and amount of use of the more affected upper extremity based on the caregivers’ perceptions in children with hemiplegic cerebral palsy: A cross-sectional study

ObjectiveTo investigate relationships between amount of use of the more affected upper extremity and functional motor and communication performance classification systems. Material and methodsThe study comprised 95 children with congenital hemiplegic cerebral palsy (CP) aged 6–15 years (52 males, 43 females; mean age 9.53, SD 3.1) and their parents/caregivers. The amount of use of the more affected upper extremity was assessed using Pediatric Motor Activity Log-Revised-How Often subscale (PMAL-R HO). Functional levels of the enrolled children were defined by the parents/caregivers using Manual Ability Classification System (MACS), Gross Motor Function Classification System-Expanded and Revised (GMFCS-E&R), and Communication Function Classification System (CFCS). ResultsA strong and negative correlation was found between PMAL-R HO subscale score and MACS (r=−0.819), suggesting that children with lower MACS levels are more likely to use their more affected upper extremity spontaneously. Additionally, negative and moderate associations between PMAL-R HO subscale score and GMFCS and CFCS were revealed (r1=−0.549 and r2=−0.567). ConclusionThe amount of use of the more affected upper extremity is more sensitive to MACS than GMFCS-E&R and CFCS. Children with a given MACS level had a wide range of PMAL-R HO subscale score. In addition to MACS, a score on the PMAL-R HO subscale related to the more affected upper extremity should be included as an inclusion criterion in clinical trials to avoid misleading effects of intervention approaches aimed at improving the amount of use of the more affected upper extremity in children with congenital hemiplegic CP.

Effect of Core Exercises on Motor Function Recovery in Stroke Survivors with Very Severe Motor Impairment

Paresis of the upper and lower limbs is a typical issue in stroke survivors. This study aims to determine whether core exercises help stroke survivors with very severe motor impairment recover their motor function. This study employed a within-subjects design. Eleven hemiparetic stroke patients with very severe motor impairment (FMA score < 35) and ages ranging from 24 to 52 years old were enrolled in this study. All participants engaged in supervised core exercise training twice a week for 12 weeks. The main outcome measures were Fugl-Meyer Assessment Lower Extremity (FMA-LE) and Fugl-Meyer Assessment Upper Extremity (FMA-UE), which were measured before training and at intervals of four weeks during training. Repeated measures ANOVA was used to analyze the effect of core exercises on motor function performance and lower extremity motor function and upper extremity motor function recovery. There were significant differences in the mean scores for motor function performance, lower extremity motor function, and upper extremity motor function throughout the four time points. A post-hoc pairwise comparison using the Bonferroni correction revealed that mean scores significantly increased and were statistically different between the initial assessment and follow-up assessments four, eight, and twelve weeks later. This study suggests that 12 weeks of core exercise training is effective for improving motor function recovery in patients with very severe motor impairment.

Multimodal physical training combined with tDCS improves physical fitness components in people after stroke: a double-blind randomized controlled trial

ABSTRACT Background Transcranial direct current stimulation (tDCS) seems to be a potential tool to optimize the long-term effects of multimodal physical training (MPT) on fitness components in post-stroke patients. Objective We investigated the effects of cortical tDCS combined with MPT on motor function reflected by strength, motor performance, and cardiorespiratory capacity in chronic stroke patients. Methods This double-blind randomized controlled trial included 18 volunteers (55 ± 10 y, 72 ± 13 kg), who underwent MPT preceded by either sham stimulation (SHAM) or 2 mA bi-hemispheric tDCS. MPT consisted of 24 sessions of 60–70 min performed 2 d/wk within 12–16 weeks, with individualized intensity. Outcomes were Fugl-Meyer scores for lower limbs (FM-LL), and total (FM-Total); speed in the 10-m walk test (10MWT); oxygen uptake and work output at maximal effort (VO2max and Wmax), and gas exchange threshold (VO2-GET and W-GET); peak torque of isokinetic knee extension (PT-EXT) and flexion (PT-FLEX) of paretic and non-paretic limbs; bilateral strength deficit during knee extension (DS-EXT) and flexion (DS-FLEX). Results Pre- vs. post-intervention improvements were detected in tDCS vs. SHAM (p < 0.05) for FM-total (29.6% vs. 15.9%; effect size [ES] = 0.78), FM-LL (35.9% vs. 9.0%; ES = 1.23), 10MWT (10.6% vs. 3.8%; ES = 0.67), Wmax (75.0% vs. 4.3%; ES = 1.68), W-GET (91.6% vs. 12.4%; ES = 1.62), PT-EXT (25.6% vs. −6.5%; ES = 1.94) and PT-FLEX (26.3% vs. 9.8%; ES = 0.65) of the paretic limb, and DS-EXT (−13.7% vs. 2.5; ES = 1.43). Conclusion Bi-hemispheric cortical tDCS optimized the effects of MPT performed with moderate volume and intensity upon muscle strength, motor function, and cardiorespiratory performance in stroke hemiparetic survivors.

The Effects of Birth Weight Index on Motor, Cognitive Function and Relationship with Some Personality Characteristics of Children

Objective: The aim of this study was to determine the effect of birth weight index on motor, cognitive function and relationship with some personality characteristics of children. Methods: Population for this study included of 32 low birth weight and 35 normal birth students randomly selected. The mean age was 8, 04 ± 1. The Movement Assessment Battery for Children-2 test was used to assess motor function and Draw-APerson Color test was used to assess cognitive function and personality characteristics. Results: The result of Manova analyses and t test indicated that normal birth children had significantly better performance in fine Motor Function and cognitive function compared to children with low birth weight. In addition, the result of Spearman correlation analyses found no significant relationship between the personality traits of the two groups. Conclusions: The findings revealed that children with normal birth had higher performance in some motor and cognitive performance compared to children with low birth weight. Therefore, it is necessary for children to benefit from intensive care and exercise interventions in terms of motor and cognition from the very first years of life.

EFEITOS DO TREINO DE CROSSFIT SOBRE A FUNÇÃO CORPORAL E NO DESEMPENHO DO MOVIMENTO DOS ATLETAS DE AERÓBICA

ABSTRACT Introduction: Physical fitness is the athletic ability to perform physical activities safely, avoiding the risk of injuries or performance-related complications on the field. CrossFit has been an effective training method for its natural movements and integration of aerobic and anaerobic exercises. It is believed that these characteristics may benefit the physical fitness of aerobic gym athletes. Objective: Evaluate the effects of CrossFit training on the physical fitness of aerobic gymnastics athletes. Methods: A controlled experimental study involving 24 aerobic gymnastics athletes was run for 9 weeks. The athletes were divided into an experimental group with CrossFit-based training, the control group received no additional training intervention. The indices of physical fitness, motor function, and movement performance were analyzed before and after the intervention. The results of the statistical analyses were discussed. Results: Considerable variation was obtained in fitness indices in distinct groups of muscle activities: in abdominal crunches from 37.66±6.12 to 50.11±3.01; medical ball lateral throw from 8.04±1.00 to 10.80±2.21; lateral bridge from 72.60±11.40 to 113.69±14.47; the flexion in sitting position from 22.52±2.51 to 26.46±1.33; and rope climbing from 32.32±7.28 to 25.97±7.08. In functional terms, the movement response time to music was optimized from 15.38±0.36 to 13.08±0.21; and the movement performance score was increased from 72.56±2.25 to 80.91±1.02. There were no significant changes in the control group. Conclusion: CrossFit training was shown to improve the physical conditioning of aerobic gym athletes and the functional movement performance of its practitioners.

Functional performance of children with Myelomeningocele submitted to intrauterine repair and conventional surgery

Introduction: Myelomeningocele (MMC) is an embryonic malformation that occurs in the first four weeks of gestation due to a failure in the closure of the neural tube. They have multifactorial etiology such as genetic and environmental factors that affect folic acid metabolism. Several anomalies may be associated with MMC, with the occurrence of hydrocephalus and Arnold Chiari type II malformation being most present. Surgical repair should ideally occur within the first 24 hours after birth to prevent or decrease the risk of infection, preservation of all viable nerve tissue, anatomical reconstitution. However, surgical repair of MMC intrauterine has shown substantial benefit in all babies submitted to this intervention. Objective: To compare the functional performance of children with MMC who underwent intrauterine surgical repair and those who did traditional surgery at birth. Methods: Cross-sectional study carried out at the UCB School-Clinic, where children treated with MMC were evaluated, analyzing their motor status and functional performance using the Pediatric Evaluation of Disability Inventory (PEDI) for a quantitative record of functional capacity and autonomy in daily activities, in the areas of self-care, mobility and social function. Results: There was a statistically significant relevance on the mobility function (p=0.01) for children who underwent intrauterine repair when compared to children who underwent traditional surgery. Conclusion: There is a strong relationship of better functionality of children who underwent intrauterine surgery when compared to children who underwent traditional surgery.

Acute Effects of Cognitive Training Game on Functional Brain Asymmetry and Motor Performance in Golf Putting: A Pilot Study

ABSTRACT Neural and behavioral evidence has indicated that video games and mental training can enhance motor skills and attentional stability. The purpose of this study is to investigate the acute effect of a single session of cognitive game training on electroencephalography (EEG) activity and golf putting performance (10, 12 ft putts). A total of twelve participants (10 males, 2 females, aged 22–59) participated in this study. Seven participants were assigned to an experimental group. This group putted before and after a 10-min of cognitive game training; five additional participants were assigned to a control group, sitting quietly with limited physical movements. Measures of EEG signals (i.e., frontal alpha asymmetry, temporal alpha asymmetry) and performance outcomes (i.e., accuracy, quality of feel) were recorded before and after the intervention. The experimental group demonstrated a significantly increased quality of putting feel compared to the control group. Although functional brain asymmetry did not approach a significant level, it was speculated that this single session of cognitive game training might stimulate approaching attention to the target (i.e., hole) and reduce mental exertions which could explain why the experimental group showed a high quality of feel in their performance. Future work is still needed with larger sample size and controlled variables (e.g., eye-dominance, handedness) to examine the long-term effects of cognitive game training on motor performance in skilled and novice golfers, respectively.

Hybrid robot-assisted gait training for motor function in subacute stroke: a single-blind randomized controlled trial

BackgroundRobot-assisted gait training (RAGT) is a practical treatment that can complement conventional rehabilitation by providing high-intensity repetitive training for patients with stroke. RAGT systems are usually either of the end-effector or exoskeleton types. We developed a novel hybrid RAGT system that leverages the advantages of both types.ObjectiveThis single-blind randomized controlled trial evaluated the beneficial effects of the novel RAGT system both immediately after the intervention and at the 3-month follow-up in nonambulatory patients with subacute stroke.MethodsWe recruited 40 patients with subacute stroke who were equally randomized to receive conventional rehabilitation either alone or with the addition of 15 RAGT sessions. We assessed lower-extremity motor function, balance, and gait performance by using the following tools: active range of motion (AROM), manual muscle test (MMT), the Fugl–Meyer Assessment (FMA) lower-extremity subscale (FMA-LE) and total (FMA-total), Postural Assessment Scale for Stroke (PASS), Berg Balance Scale (BBS), Tinetti Performance-Oriented Mobility Assessment (POMA) balance and gait subscores, and the 3-m and 6-m walking speed and Timed Up and Go (TUG) tests. These measurements were performed before and after the intervention and at the 3-month follow-up.ResultsBoth groups demonstrated significant within-group changes in the AROM, MMT, FMA-LE, FMA-total, PASS, BBS, POMA, TUG, and 3-m and 6-m walking speed tests before and after intervention and at the 3-month follow-up (p < 0.05). The RAGT group significantly outperformed the control group only in the FMA-LE (p = 0.014) and total (p = 0.002) assessments.ConclusionAlthough the novel hybrid RAGT is effective, strong evidence supporting its clinical effectiveness relative to controls in those with substantial leg dysfunction after stroke remains elusive.Trial registration The study was registered with an International Standard Randomized Controlled Trial Number, ISRCTN, ISRCTN15088682.

Feasibility, safety, and efficacy of 12-week side-to-side vibration therapy in children and adolescents with congenital myopathy in New Zealand

This pilot study explored the feasibility and effectiveness of vibration therapy (VT) on muscle and bone health, motor performance, and respiratory function in patients with congenital myopathy (CM). Eleven participants with CM (11.5 ± 2.8 years) underwent 12 weeks of side-alternating VT at 20 Hz for nine minutes per session, four days a week. VT was preceded by a 12-week control period. Assessments included dual-energy X-ray absorptiometry scans, 6-minute walk and 10-meter run tests, muscle function and motor performance assessment, dynamometry, and pulmonary function. VT was well-tolerated, with occasional mild itchiness reported. The median compliance level with VT treatment was 75%. 12 weeks of VT improved the total score of motor function performance by 2.4 units (p=0.006) and velocity rise maximum of the chair rising test by 0.11 m/s (p=0.029). VT was shown to be feasible, safe, and associated with improving motor function performance. Our findings support further exploration of VT's potential health benefits to patients with CM in larger studies involving a longer intervention period.

A Review of the Measurement of the Neurology of Gait in Cognitive Dysfunction or Dementia, Focusing on the Application of fNIRS during Dual-Task Gait Assessment

Poor motor function or physical performance is a predictor of cognitive decline. Additionally, slow gait speed is associated with poor cognitive performance, with gait disturbances being a risk factor for dementia. Parallel declines in muscular and cognitive performance (resulting in cognitive frailty) might be driven primarily by muscle deterioration, but bidirectional pathways involving muscle–brain crosstalk through the central and peripheral nervous systems are likely to exist. Following screening, early-stage parallel declines may be manageable and modifiable through simple interventions. Gait–brain relationships in dementia and the underlying mechanisms are not fully understood; therefore, the current authors critically reviewed the literature on the gait–brain relationship and the underlying mechanisms and the feasibility/accuracy of assessment tools in order to identify research gaps. The authors suggest that dual-task gait is involved in concurrent cognitive and motor activities, reflecting how the brain allocates resources when gait is challenged by an additional task and that poor performance on dual-task gait is a predictor of dementia onset. Thus, tools or protocols that allow the identification of subtle disease- or disorder-related changes in gait are highly desirable to improve diagnosis. Functional near-infrared spectroscopy (fNIRS) is a non-invasive, cost-effective, safe, simple, portable, and non-motion-sensitive neuroimaging technique, widely used in studies of clinical populations such as people suffering from Alzheimer’s disease, depression, and other chronic neurological disorders. If fNIRS can help researchers to better understand gait disturbance, then fNIRS could form the basis of a cost-effective means of identifying people at risk of cognitive dysfunction and dementia. The major research gap identified in this review relates to the role of the central/peripheral nervous system when performing dual tasks.

Sex-Specific Causes and Consequences of White Matter Damage in a Middle-Aged Cohort.

ObjectiveTo evaluate potential sex-specific effects of multiple cardiovascular risk factors on white matter pathology in normal aging men and women, as well as potential sex-differences in the association of white matter pathology and cognitive functions.MethodsWe analyzed cross-sectional data of 581 participants (median age: 53 years, 54% women) of the population-based cohort of the BiDirect Study who completed clinical examinations, five neuropsychological tests, and an 3T MRI examination. White matter pathology was determined by the extent of white matter hyperintensities (WMH) on FLAIR images as well as the magnitude of global fractional anisotropy (FA) based on diffusion tensor imaging. Main effects, interaction as well as sex-stratified generalized linear regression models were used to evaluate the moderating effect of sex on the association of hypertension, diabetes mellitus, smoking, and obesity with WMH and FA, respectively. Associations of imaging markers with cognitive test results were determined with linear regression models.ResultsHypertension showed stronger associations with more extensive WMH and less FA in women compared to men. Current smoking was associated with more severe WMH in women only. Adjusted for age and education, WMH were not significantly associated with cognitive tests, but higher FA was associated with better performance in motor function in both sexes and with executive functions in men, even after adjustment for cardiovascular risk factors.ConclusionWe observed a stronger association of hypertension and smoking with white matter damage in women, suggesting a higher susceptibility for vascular pathology in women. However, there was no association of WMH with cognition, and FA was associated with executive function tests only in men, suggesting a higher cognitive reserve in women.

Development of the Gross Motor Function Family Report (GMF-FR) for Children with Cerebral Palsy.

Purpose: To describe the initial steps in the development of a family-completed, modified version of the Gross Motor Function Measure (GMFM-88) to report gross motor function of young people with cerebral palsy in their natural environments. Methods: Development of the Gross Motor Function - Family Report (GMF-FR) was based on expert opinion involving 13 experienced clinicians and researchers, in four steps: (1) item identification to target items that reflect functional gross motor performance; (2) item selection; (3) critical analysis of the items; and (4) item and scoring modification. Results: Several modifications to existing items and scoring were made, including wording changes to optimize ease of families' understanding, the addition of photographs to illustrate all items, changes to the items to enable use of furniture instead of specialized equipment, and modifications to scoring criteria to ensure a focus on functional motor skills. Ultimately, 30 items were selected, and specific testing/scoring instructions were created for each item. Conclusions: GMF-FR is a new family-report tool, based on the GMFM-88. When validated, it can be used as a telehealth outcome measure to capture family-reported functional motor skill performance in home and community environments.

Muscular Function as an Alternative to Identify Cognitive Impairment: A Secondary Analysis From SABE Colombia.

BackgroundIdentification of cognitive impairment is based traditionally on the neuropsychological tests and biomarkers that are not available widely. This study aimed to establish the association between motor function (gait speed and handgrip strength) and cognitive performance in the Mini-Mental State Examination, globally and by domains. A secondary goal was calculating a cut-off point for gait speed and handgrip strength to classify older adults as cognitively impaired.MethodsThis is a secondary analysis of SABE Colombia (Salud, Bienestar & Envejecimiento), a survey that was conducted in 2015 on health, wellbeing, and aging in Colombia. This study used linear regression models to search for an association between motor function and cognitive performance. The accuracy of motor function measurements in identifying cognitive impairment was assessed with receiver operating characteristic (ROC) curves. This study also analyzed other clinical and sociodemographical variables.ResultsGait speed was associated with orientation (r2 = 0.16), language (r2 = 0.15), recall memory (r2 = 0.14), and counting (r2 = 0.08). Similarly, handgrip strength was associated with orientation (r2 = 0.175), language (r2 = 0.164), recall memory (r2 = 0.137), and counting (r2 = 0.08). To differentiate older adults with and without cognitive impairment, a gait speed cut-off point of 0.59 m/s had an area under the curve (AUC) of 0.629 (0.613–0.646), and a weak handgrip (strength below 17.5 kg) had an AUC of 0.653 (0.645-0.661). The cut-off points for handgrip strength and gait speed were significantly higher in male participants.ConclusionsGait speed and handgrip strength are similarly associated with the cognitive performance, exhibiting the most extensive association with orientation and language domains of the Mini-Mental State Examination. Gait speed and handgrip strength can easily be measured by any clinician, and they prove to be useful screening tools to detect cognitive impairment.

The Relationship Between Functional Motor Competence and Performance on the Army Combat Fitness Test in Army Reserve Officer Training Corps Cadets.

The development of functional motor competence (FMC; i.e., neuromuscular coordination and control required to meet a wide range of movement goals) is critical to long-term development of health- and performance-related physical capacities (e.g., muscular strength and power, muscular endurance, and aerobic endurance). Secular decline in FMC among U.S. children and adolescents presents current and future challenges for recruiting prospective military personnel to successfully perform the physical demands of military duty. The purpose of the current study was to examine the relationship between FMC and physical military readiness (PMR) in a group of Cadets enrolled in an Army Reserve Officer Training Corps program. Ninety Army Reserve Officer Training Corps Cadets from a southeastern university and a military college in the southeast (females = 22; Mage = 19.5 ± 2.5) volunteered for participation in the study. Cadets performed a battery of eight FMC assessments consisting of locomotor, object projection, and functional coordination tasks. To assess PMR, Cadets performed the Army Combat Fitness Test (ACFT).Values from all FMC assessments were standardized based on the sample and summed to create a composite FMC score. ACFT scores were assigned to Cadets based upon ACFT scoring standards. We used Pearson correlations to assess the relationships between individual FMC assessment raw scores, FMC composite scores, and total ACFT points. We also evaluated the potential impact of FMC on ACFT in the entire sample and within each gender subgroup using hierarchical linear regression. Finally, we implemented a 3 × 2 chi-squared analysis to evaluate the predictive utility of FMC level on pass/fail results on the ACFT by categorizing Cadets' composite FMC score into high (≥75th percentile) moderate (≥25th percentile and <75th percentile), and low (<25th percentile) based on the percentile ranks within the sample. ACFT pass/fail results were determined using ACFT standards, requiring a minimum of 60 points on each the ACFT subtests. FMC composite scores correlated strongly with total ACFT performance (r = 0.762) with individual FMC tests demonstrating weak-to-strong relationships ACFT performance (r = 0.200-0.769). FMC uniquely accounted for 15% (95% CI: -0.07 to 0.36) of the variance in ACFT scores in females (R2 = 0.516, F2,19 = 10.11, P < 0.001) and 26% (95% CI: 0.09-0.43) in males (R2 = 0.385, F2,65 = 20.37, P < 0.001), respectively, above and beyond the impact of age. The 3 × 2 chi-squared analysis demonstrated 74% of those with low, 28% with moderate, and 17% with high FMC failed the ACFT (χ2 [1, N = 90] = 27.717, V = 0.555, P < 0.001). FMC composite scores are strongly correlated with ACFT scores, and low levels of FMC were a strong predictor of ACFT failure. These data support the hypothesis that the development of sufficient FMC in childhood and adolescence may be a critical antecedent for PMR. Efforts to improve FMC in children and adolescents may increase PMR of future military recruits.

The Effectiveness of Occupational Therapy Handwriting Intervention for Children with Motor Coordination Issues: A Systematic Review

Handwriting difficulty is one of the main issues among school children, especially for those with motor coordination issues. The aim of this systematic review is to evaluate the effectiveness of occupational therapy interventions in handwriting components for children with motor coordination issues. Current research articles were systematically searched according to the PRISMA guidelines. Two hundred and sixty-eight (n=268) research articles were identified; however, only ten (n=10) were eligible to be evaluated for this study. Studies were appraised by using McMaster Critical Review Form-Quantitative Studies. Descriptive synthesis was executed due to the heterogeneity of included studies. The review found various types of intervention conducted by occupational therapists to have a positive effect on handwriting performance components among children with motor coordination issues. Types of intervention used were visual, motor, perceptual, sensory, activity of daily living skills, training device and assistive technology and specific handwriting programs. Most handwriting intervention showed effectiveness to improve handwriting performance in motor function, visual and perceptual components. Future research should focus on homogeneity of Occupational Therapy (OT) intervention to improve handwriting performance by using specific handwriting programmes and similar standardised evaluation instruments. Practitioners of OT intervention should consider collaboration with teachers, parents and other health professionals to expedite effectiveness of intervention in handwriting performance components.
