Foot Orthotic

One hundred thirty-two female basketball players were observed for lower-extremity overuse injury between 1993 and 2004. Athletes studied between 1993 and 1996 did not receive foot orthotic devices and composed the control group. The treatment group comprised athletes studied between 1996 and 2004. Athletes in the treatment group were given a foot orthotic device before participation in basketball. Data analysis included lower-extremity overuse injury rates and the effect of foot orthotic devices on lower-extremity overuse injury rates by means of an incidence density ratio. The control group had a lower-extremity overuse injury rate of 5.37 per 1,000 exposures, and the treatment group had a rate of 6.44 per 1,000 exposures. The incidence density ratio was not significant (P = .44). This study rejects the concept that foot orthotic devices may assist in prevention of lower-extremity overuse injury in female basketball players. (J Am Podiatr Med Assoc 96(5): 408–412, 2006)

Context Hopping exercises are recommended as a functional training tool to prevent lower limb injury, but their effects on lower extremity biomechanics in those with chronic ankle instability (CAI) are unclear. Objective To determine if jump-landing biomechanics change after a hop-stabilization intervention. Design Randomized controlled clinical trial. Setting Research laboratory. Patients or Other Participants Twenty-eight male collegiate basketball players with CAI were divided into 2 groups: hop-training group (age = 22.78 ± 3.09 years, mass = 82.59 ± 9.51 kg, height = 187.96 ± 7.93 cm) and control group (age = 22.57 ± 2.76 years, mass = 78.35 ± 7.02 kg, height = 185.69 ± 7.28 cm). Intervention(s) A 6-week supervised hop-stabilization training program that consisted of 18 training sessions. Main Outcome Measure(s) Lower extremity kinetics and kinematics during a jump-landing task and self-reported function were assessed before and after the 6-week training program. Results The hop-stabilization program resulted in improved self-reported function (P < .05), larger sagittal-plane hip- and knee-flexion angles, and greater ankle dorsiflexion (P < .05) relative to the control group. Reduced frontal-plane joint angles at the hip, knee, and ankle as well as decreased ground reaction forces and a longer time to peak ground reaction forces were observed in the hopping group compared with the control group after the intervention (P < .05). Conclusions The 6-week hop-stabilization training program altered jump-landing biomechanics in male collegiate basketball players with CAI. These results may provide a potential mechanistic explanation for improvements in patient-reported outcomes and reductions in injury risk after ankle-sprain rehabilitation programs that incorporate hop-stabilization exercises.

The purpose of this study was to analyze the influence of a custom foot orthotic (CFO) intervention on lower extremity intralimb coupling during a 30-min run in a group of injured runners and to compare the results to a control group of healthy runners. Three-dimensional kinematic data were collected during a 30-min run on healthy female runners (Shoe-only) and a group of female runners who had a recent history of overuse injury (Shoe-only and Shoe with custom foot orthoses). Results from the study revealed that the coordination variability and pattern for the some couplings were influenced by history of injury, foot orthotic intervention and the duration of the run. These data suggest that custom foot orthoses worn by injured runners may play a role in the maintenance of coordination variability of the tibia (transverse plane) and calcaneus (frontal plane) coupling during the Early Stance phase. In addition, it appears that the coupling angle between the knee (transverse plane) and rearfoot (frontal plane) joints becomes more symmetrical in the late stance phase as a run progresses.

To investigate the effect of intelligent exercise training equipment on lower limb function and standing stability of stroke patients with hemiplegia in clinical nursing of neurology department. Forty-eight stroke patients with a course of 1 to 3 months were randomly divided into treatment group and control group, with 24 cases in each group. The control group was treated with conventional rehabilitation training, and the treatment group was treated with intelligent training system, twice a day, 20 min each time. Lower extremity motor function (using the FMA-L scale) and walking function (using the functional walking scale FAC) were assessed before treatment and 4 weeks after treatment. The results showed that there was no statistical difference between the control group and the treatment group in the t-test of lower limb motor function scores before rehabilitation treatment ( P > 0.05 ). After treatment, the lower extremity motor function scores of the two groups were tested by group design T-test, and the results showed that there was a significant difference between the two groups ( P < 0.05 ); The effect of the treatment group was significantly better than that of the control group ( P < 0.05 ). Intelligent exercise training equipment combined with routine rehabilitation therapy in clinical nursing of neurology department could improve the lower extremity motor function and walking ability of patients with convalescence stroke hemiplegia, and the effect was better than that of routine rehabilitation therapy alone.

Extremity Injuries

Background: Lower extremity injuries are common in high school sports and are costly, and some have poor outcomes. The FIFA 11+ injury prevention program has been shown to decrease injuries in elite athletes by up to 72%. Hypothesis: High schools in which coaches implement the FIFA 11+ injury prevention program in their athletic programs will have a decreased incidence of lower extremity injuries compared with schools using their usual prepractice warm-up. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: Fourteen high schools that employed an athletic trainer were randomly assigned to either the FIFA 11+ group or control group (usual warm-up routine). Exposure to sports and injuries were recorded and used to determine the incidence rates of lower extremity injuries per athlete-exposure (AE). The FIFA 11+ program was implemented by coaches and complicance with the program recorded. Results: There were 196 lower extremity injuries among 1825 athletes in the FIFA 11+ group and 172 injuries among 1786 athletes in the control group (1.59 and 1.47 injuries per 1000 AEs, respectively; P = .771). The distribution of the types of injury in the 2 groups did not differ, but the body locations where the injuries occurred differed somewhat ( P = .051). The FIFA 11+ group had larger proportions of thigh and foot injuries, while the control group had higher proportions of knee and ankle injuries. Group differences in injury rates varied with sport ( P = .041 for interaction), but there were no significant differences in injury rates between the FIFA 11+ and control groups by sport, level of play, and sex. In the FIFA 11+ group, 62% of the coaches reported that their teams completed the full FIFA 11+ program at least once a week, and 32% reported that they completed it at least twice a week. Conclusion: This study did not demonstrate a reduction in lower extremity injuries in schools randomized to use the FIFA 11+ program compared with schools using their usual prepractice warm-up program. Coach-reported compliance with performing the FIFA 11+ program at least twice a week was low.

Context: Evaluating the translatability and feasibility of an intervention program has become as important as determining the effectiveness of the intervention. Objective: To evaluate the applicability of a 3-month jump-landing training program in basketball players, using the RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) framework. Design: Randomized controlled trial. Setting: National and regional basketball teams. Patients or Other Participants: Twenty-four teams of the second highest national division and regional basketball divisions in Flanders, Belgium, were randomly assigned (1:1) to a control group and intervention group. A total of 243 athletes (control group = 129, intervention group = 114), ages 15 to 41 years, volunteered. Intervention(s): All exercises in the intervention program followed a progressive development, emphasizing lower extremity alignment during jump-landing activities. Main Outcome Measure(s): The results of the process evaluation of the intervention program were based on the 5 dimensions of the RE-AIM framework. The injury incidence density, hazard ratios, and 95% confidence intervals were determined. Results: The participation rate of the total sample was 100% (reach). The hazard ratio was different between the intervention group and the control group (0.40 [95% confidence interval = 0.16, 0.99]; effectiveness). Of the 12 teams in the intervention group, 8 teams (66.7%) agreed to participate in the study (adoption). Eight of the participating coaches (66.7%) felt positively about the intervention program and stated that they had implemented the training sessions of the program as intended (implementation). All coaches except 1 (87.5%) intended to continue the intervention program the next season (maintenance). Conclusions: Compliance of the coaches in this coach-supervised jump-landing training program was high. In addition, the program was effective in preventing lower extremity injuries.

Context: Neuromuscular control deficit has been reported in people with chronic ankle instability (CAI) and hopping exercises have been recommended as a functional training tool to prevent lower limb injury, but its effects on lower-extremity neuromuscular control in those with CAI are unclear. Objective: To investigate the effect of hop stabilization training on neuromuscular control and self-reported function in college basketball players with CAI. Study Design: A randomized controlled trial. Setting: Research Laboratory. Patients (or Other Participants): A total of 28 college basketball players with CAI were randomly assigned to the experimental hop stabilization group (age = 22.78 [3.09] y, weight = 82.59 [9.51] kg, and height = 187.96 [7.93] cm) or the control group (age = 22.57 [2.76] y, weight = 78.35 [7.02] kg, and height = 185.69 [7.28] cm). Intervention: Participants in the experimental group performed supervised hop stabilization exercises 3 times per week for 6 weeks. The control group received no intervention. Main Outcome Measures: Preparatory and reactive muscle activation levels and muscle onset time were assessed from 8 lower-extremity muscles during a jump-landing task before and after the 6-week training program. Results: Significant improvements in preparatory muscle activation, reactive muscle activation, and muscle onset time were noted across the lower-extremity in the experimental group relative to the control group (P < .05). Self-reported function also improved in the experimental group relative to the control group (P < .05). Conclusions: These findings demonstrate that 6 weeks of hop stabilization training is effective in improving neuromuscular control and self-reported function in college basketball players with CAI. Hop stabilization exercises can be incorporated into the rehabilitation program for CAI.

ObjectivesElectronic dance music (EDM) concerts are becoming increasingly popular. Strong stroboscopic light effects are commonly part of these shows, and may provoke seizures in individuals with photosensitive epilepsy. This study aims to examine the risk of epileptic seizures during EDM concerts.Setting28 EDM concerts taking place in The Netherlands.ParticipantsWe describe a young man who experienced a seizure during an EDM concert, and who later showed a positive electroencephalographic provocation test during exposure to video footage of the same concert. Subsequently, we performed a cohort study of 400 343 visitors to EDM concerts, divided in those exposed (concert occurring in darkness) versus unexposed (concert in daylight) to stroboscopic light effects.ResultsIn total, 400 343 EDM concert visitors were included: 241 543 (representing 2 222 196 person hours) in the exposed group and 158 800 (representing 2 334 360 person hours) in the control group. The incidence density ratio of epileptic seizures in exposed versus unexposed individuals was 3.5 (95% CI: 1.7 to 7.8; p<0.0005). Less than one-third of cases occurred during use of ecstasy or similar stimulant drugs.ConclusionStroboscopic light effects during EDM concerts occurring in darkness probably more than triple the risk of epileptic seizures. Concert organisers and audience should warn against the risk of seizures and promote precautionary measures in susceptible individuals.

The objective of this study is the comparison of lower and higher extremity anaerobic power capacities of indoor athletes. 25 handball players (13 females, 12 males), 22 basketball players (10 females, 12 males) and experimental control group (10 females, 13 males, total 23), it means 70 athletes from amateur leagues participated in the research. Lower extremity anaerobic powers of participants were measured by wattbike pro power bike. Higher extremity anaerobic powers of participants were measured by myotest. Data statistics were done by Windows SPSS 22.0. For dispersion of averages and standart deviations, descriptive statistics methods were used. In order to see the effects of gender and branch variances of participants on lower and higher extremity, Two-Way Manova analysis was used. Moreover, in order to see differences clearly, Screen Plot graphics were performed. In higher extremity measurements analysis, for 3 higher extremity values except velocity, male participants had higher averages than female participants do (p &lt; 0.05). Based on Pairwise Comparisons results for branches, both Power Wkg and Power Max W kg values, handball participants had significant higher averages than control group participants did (p &lt; 0.05). For lower extremity variances, female participants had lower averages than male participants. For Powermass values, handball players had higher averages than control group did. For Powerpeak and Power Average variances, control group participants had significant lower averages than both basketball players and handball players did (p &lt; 0.05). For all values, there were no significant differences between handball and basketball players, except male height measurements (p &gt; 0.05).
