    One of the most common forms of entrapment neuropathy is Carpal Tunnel Syndrome (CTS). There are various treatment options for CTS. However, there are no clear and structured guidelines. This review classified the existing treatments and developed an algorithm to help physicians to choose the best option for their patients. Treatment options were summarized in three sections: non-surgical management of CTS, post-operative management of CTS, and practical open carpal tunnel release post-op protocol. The physicians can prescribe multiple treatment options to CTS patients. Corticosteroid in oral or injectable form has strong evidence in pain control and functional improvement in the short term. Shockwave therapy and nocturnal wrist splints display moderate therapeutic effects. Post carpal tunnel release rehabilitation can be started a few days after the operation.

    Sport has become increasingly competitive, prompting the need to determine, as far as possible, any likely performance advantage. While the focus of athletic research, testing, and training is on the physiological and physical characteristics of the sport, visual abilities not only affect sport performance directly, but also affect the acquisition of motor skills. Vision, and visual-spatial intelligence (VSI), are a relatively new and underexplored area of athletic performance. As with physiological and physical parameters, a range of factors affect vision and VSI in sporting activities. This review of the literature is a first attempt to summarize and compile an overview of the factors affecting vision and VSI in athletes, covering those previously connected with sport, as well as those hitherto not associated with athletic activities, but that could also play a part in sports performance. The evidence from this review suggests that while current research still tends to focus on single factors affecting vision and VSI, a large number of such factors have been identified that could affect vision and VSI. This offers new opportunities for researchers to investigate the effects of a combination of factors, and for conditioning and/or sports vision specialists to explore further possibilities for competitive advantage.

    Background

    Kaempfera (K.) parviflora (i.e., Thai ginseng) is believed to have medicinal properties associated with good health (e.g., increased vitality, metabolism booster) because it expands blood vessels, which allows for increased blood flow. These effects might extend into the realm of improving physical performance, specifically that of the cardiovascular system.

    Objectives

    A randomized, placebo-controlled, parallel design study was conducted to determine the effects of 12 weeks of K. parviflora supplementation on the cardiovascular endurance of healthy male adults.

    Methods

    Participants included 57 Thai air force cadets who were undergoing physical training for sports competition. Participants were randomly divided into either the treatment group (n = 30) (Age = 20.30 + 0.65 yrs.) or control group (n = 27) (Age = 20.37 + 0.68 yrs.). Treatment group participants received 360 mg of K. parviflora extract in capsule form, and those in the control group received a placebo capsule. Measurements included lactate threshold and heart rate recovery, assessed at baseline and weeks 6 and 12. Group differences were assessed using a 2 (group) × 3 (time) repeated-measures ANOVA.

    Results

    No main or interaction effects were observed for the lactate threshold (all P > 0.05). No group differences were observed for heart rate recovery (P > 0.05); however, a significant time effect was observed for heart rate recovery at weeks 6 and 12 (P < 0.05), which also marked the beginning of an interaction effect showing that those in the experimental group improved more than those in the control group (P > 0.05).

    Conclusions

    In this set of observations, 12-weeks of K. parviflora supplementation had no effect on the lactate threshold; however, it does appear that it might have improved heart rate recovery

    Background

    Postural stability is quite mandatory when practicing high-performance sports. Investigations of postural stability and related variables in judokas with visual impairment can lead to new training plans targeting the improvement of postural stability and ultimately to enhanced performance.

    Objectives

    To investigate postural stability and its relationship with anthropometric measurements, body composition, and experience in judokas with visual impairment.

    Methods

    Seventeen judokas (70.6% men) with visual impairment participated in this cross-sectional study. The athletes were grouped based on the functional classification of partial (B2/B3, n = 10) and total visual impairment (B1, n = 7). Postural stability was assessed using the elliptical area of the 95% confidence interval (Area) and the average displacement velocity (Vavg) while remaining in a bipedal stance with eyes closed and blindfolded. Body mass, height, circumferences, skinfold thickness and diameters were measured and used to estimate body composition. Between-group comparisons were evaluated using the Mann-Whitney test. Bivariate correlations were determined with Spearman’s correlation coefficient with bootstrap analysis and 95% confidence interval (95% CI) from 500 resamplings.

    Results

    No significant difference was observed between the B1 and B2/B3 groups in relation to postural stability (Area; P = 1.00; Vavg; P = 0.85). Postural stability (Area but not Vavg) correlated positively and moderately (P < 0.05) with anthropometric measurements and negatively with judo experience (practice time).

    Conclusions

    The postural stability of judokas was unrelated to the degree of visual impairment. Postural instability was correlated with anthropometric measurements, mainly body fat and height, and judo experience.

    Background

    Aerobic exercise has been shown to decrease the functional disorders related to multiple sclerosis (MS). Nevertheless, the effect of aerobic exercise training on the cytokines and neuroprotective mediators associated with the disease activity has remained relatively unknown.

    Objectives

    The present research was conducted to evaluate the responses of the vascular endothelial growth factor (VEGF) and tumor necrosis factor-alpha (TNF-α) to single-bout and six-week aerobic exercise training in the patients with MS.

    Methods

    Totally, 20 subjects ((n = 10) patients with MS and (n = 10) controls) who were matched in terms of gender, weight, body mass, and age were included in the study. Participants received aerobic exercise training at approximately 60% of VO2max in 30-min sessions 3 times a week for six weeks. Serum concentrations of the VEGF and TNF-α were analyzed pre- and post-exercise training (in the first session and after 18 sessions of the study).

    Results

    Serum concentration of the TNF-α decreased significantly after a single bout and 6-week aerobic exercise training (P = 0.002 and P = 0.005) in the intervention group. Serum concentration of the VEGF increased significantly only after exercise in the first and 18th sessions in the intervention group (P = 0.017 and P = 0.022).

    Conclusions

    Our results revealed that exercise may influence the VEGF regulation in patients with MS. Although, further research is needed to determine the effect of exercise on the immune variables in patients with MS.
