Interventions based on everyday motor skills have been developed to be effective in children with developmental coordination disorder (DCD). The purpose of the present study was to examine the effects of motor skill training on exercise tolerance and cardiorespiratory fitness in children with DCD. Children were assigned to 3 groups: an experimental training group comprising 14 children with DCD, a control nontraining group comprising 13 children with DCD, and a control nontraining group comprising 14 typically developed children. All participants were tested twice with an interval of 8-weeks on a cardiopulmonary exercise test, pulmonary function testing, and a 6-min walk test. After the training program the maximal power output was significantly increased for DCD group at anaerobic threshold (p < 0.05) and at peak level (maximal oxygen uptake, p < 0.001). Improvement in power output was more pronounced at the anaerobic threshold (t (13) = -5.21, p < 0.001) than at the maximal intensity (maximal oxygen uptake, t (13) = -3.08, p < 0.01) in the DCD training group. Children with DCD that participated in the training program improved their walking distance (t (13) = -9.08, p < 0.001), had a higher maximum heart rate (t (13) = -3.41, p < 0.01), and reduced perceived exertion (t (13) = 2.75, p < 0.05). The DCD nontraining group and the typically developed group did not change on any of the measures. In conclusion, training delayed reaching the anaerobic threshold and improved aerobic endurance and exercise tolerance in children with DCD.

The purpose of the present study was to examine the effect of a group-based task oriented skills training program on motor and physical ability for children with DCD. It was also investigated if there was an effect on fine motor and handwriting tasks that were not specifically practiced during the training program. Forty-one children aged 6-10years took part in this study. Children were assigned to three groups: an experimental training group consisting of 14 children with DCD, a control non-training group consisted of 13 children with DCD and a control non-training group consisting of 14 typically developed children. The measurements included were, the Movement Assessment Battery for Children (MABC), the Modified Agility Test (MAT), the Triple Hop Distance (THD), the 5 Jump-test (5JT) and the Handwriting Performance Test. All measures were administered pre and post an 8-week training program. The results showed that 10 children of the DCD training-group improved their performance in MABC test, attaining a score above the 15th percentile after their participation in the training program. DCD training-group showed a significant improvement on all cluster scores (manual dexterity (t (13)=5.3, p<.001), ball skills (t (13)=2.73, p<.05) and balance (t (13)=5.13, p<.001). Significant performance improvements were also found in MAT, THD, 5JT (t (13)=-4.55; p<.01), handwriting quality (t (12)=-2.73; p<.05) and speed (t (12)=-4.2; p<.01) after the training program. In conclusion, improvement in both practiced and non-practiced skills, in the training program, may reflect improvement in motor skill but also transfer to other skills.

The decreased participation in physical activity by children with probable developmental coordination disorder (pDCD) has raised concerns about their aerobic fitness and lung function levels. The purpose of the present study was to examine assessment of cardiorespiratory and neuromotor fitness, using laboratory-based tests during an incremental treadmill protocol in healthy children with and without pDCD. Twenty sex children ages 6-9 years took part in this study. Motor coordination was assessed using the Movement Assessment Battery for Children (MABC). All participants performed a cardiopulmonary exercise test (CPET) on a cycle ergometer. Pulmonary function was assessed by spirometric measurements (forced vital capacity: FVC, forced expiratory volume in 1s: FEV1) and walking distance (6MWD) was assessed using the 6-min walking test. The children with pDCD had lower VO2max than children without pDCD (p < 0.01). Moreover, FVC and FEV1 were significantly higher in children without pDCD than in children with the disorder (p < 0.05, p < 0.01 respectively). Likewise, children with pDCD had poorer performance on the 6MWD than children without pDCD (p < 0.01). A significant correlation between the absolute value for FEV1 and 6MWD (r = 0.637, p < 0.05) in pDCD group was observed. We found a significant correlation between VO2max and MABC score (r = -0.612, p < .001) and between VO2max and 6MWD (r = 0.502, p < .001) for all children. Moreover, a significant correlation between VO2max and FEV1 (r = 0.668, p < .05) was found in children with pDCD. Overall, the reduced aerobic capacity of DCD was associated with decreased of lung function, as well as an alteration of peripheral muscle responses.

Children with developmental coordination disorder (DCD) have been shown to be less physically fit when compared to their typically developing peers. The purpose of the present study was to examine the relationships among body composition, physical fitness and exercise tolerance in children with and without DCD. Thirty-seven children between the ages of 7 and 9 years participated in this study. Participants were classified according to results obtained on the Movement Assessment Battery for Children (MABC) and were divided in 2 groups: 19 children with DCD and 18 children without DCD. All children performed the following physical fitness tests: The five-jump test (5JT), the triple-hop distance (THD) and the modified agility test (MAT). Walking distance was assessed using the 6-min walking test (6MWT). Children with DCD showed higher scores than children without DCD in all MABC subscale scores, as well as in the total score (p<0.001). Participants with DCD were found to perform significantly worse on the MAT (p<0.001), the THD (p<0.001) and 5JT (p<0.05). Moreover, children with DCD had poorer performance on the 6MWT than children without DCD (p<0.01). Our results found significant correlations among body mass index (BMI), THD (r=0.553, p<0.05), 5JT (r=0.480, p<0.05) and 6MWT (r=0.544, p<0.05) only in DCD group. A significant correlation between MAT and 5JT (r=-0.493, p<0.05) was found. Similarly, THD and 5JT (r=0.611, p<0.01) was found to be correlated in children with DCD. We also found relationships among 6MWT and MAT (r=-0.522, p<0.05) and the 6MWT and 5JT (r=0.472, p<0.05) in DCD group. In addition, we found gender specific patterns in the relationship between exercise tolerance, explosive strength, power, DCD, and BMI. In conclusion, the present study revealed that BMI was indicative of poorer explosive strength, power and exercise tolerance in children with DCD compared to children without DCD probably due to a limited coordination on motor control.

OBJECTIVES To reappraise the respective involvement of small- and large-fiber damage in carpal tunnel syndrome (CTS) and to determine the diagnostic sensitivity of autonomic tests compared to conventional nerve conduction study (NCS). METHODS Thirty-two manual workers complaining of at least unilateral CTS were enrolled. They underwent clinical interview and completed the symptom severity scale of the Boston CTS Questionnaire (sssBCTQ) and the Neuropathic Pain Symptom Inventory (NPSI). In addition, transcarpal NCS was performed to investigate large sensory and motor fibers of the median nerve, while small autonomic fibers were assessed by recording sympathetic skin reflexes (SSR) at the palm and by grading skin wrinkling in response to eutectic mixture of local anesthetic (EMLA) cream application at the pulp of the index finger. For each neurophysiological variable, sensitivity and specificity values for the diagnosis of CTS were calculated and clinical correlations were studied. RESULTS Among 64 hands examined, 36 were clinically symptomatic, while 22 were clinically asymptomatic and served as controls. Among all the neurophysiological variables studied, only the values of transcarpal sensory nerve conduction velocity and the EMLA test grade were found to be more altered in clinically symptomatic hands, with also a trend towards prolonged distal motor latency. Overall, for the diagnosis of clinically symptomatic CTS, NCS, SSR, and the EMLA test had a sensitivity of 66.7%, 22.2%, and 69.4%, respectively, and a specificity of 72.7%, 90.9%, and 50%, respectively. Combining NCS and the EMLA test led to a sensitivity of 88.9% and a specificity of 45.4%. The sssBCTQ (r=-0.34, P=0.009) and the total NPSI score (r=-0.41, P=0.001) correlated to a more altered EMLA test grade, but not to any NCS or SSR variables. In symptomatic hands, burning sensation was associated with more severe small-fiber lesion, while other pain and sensory symptoms were rather found to be reduced in case of large-fiber damage, evidenced by NCS alteration. CONCLUSIONS This study confirms the discrepancy between conventional NCS results and clinical presentation of CTS, but still suggests a major involvement of Aβ fibers in the positive sensory symptoms of CTS, excepting burning sensation. On the other hand, the EMLA test was found to correlate with clinical data and to be able to improve sensitivity of neurophysiological investigation in diagnosing CTS.

Background: Exercise induced bronchospasm (EIB) commonly occurs during exercise. The comparative effects of different sports on airway responsiveness among prepubertal boys remain to be determined. Objectives: To assess differences in post exercise spirometry between footballers, judokas and a control group in prepubertal boys. Patients and Methods: A total of ninety six prepubertal boys were studied. Bronchial hyper responsiveness (BHR) to exercise challenge test was defined by a diagnosis of baseline spirometry, followed by an incremental exercise test. To date, the best test to confirm EIB may simply be standard pulmonary function testing before and after high-intensity exercise. A 10% or greater post-challenge fall in forced expiratory volume in FEV1 is used as a diagnostic criterion. Results: There was no significant difference in baseline spirometry between all groups (P > 0.05). The post exercise spirometry test revealed the presence of EIB in 16 of 32 (50%) footballers against 9 out of 32 (28.12%) in both judokas and control subjects at 5 min after the exercise. Also, there was a significantly higher decrease (P < 0.05) in mean FEV1 at 5 minuts in footballers (-9.60 ± 6.18) compared to judokas (-5.41 ± 5.85). Conclusions: The footballers have more BHR than judokas, especially at 5min after the exercise. This may be due to prolonged hyperventilation, atopy and increased exposure to inhaled allergens and pollutants during training and competition.
