Context: Decreased postural balance is a primary risk factor for lower-limb injuries. Cryotherapy is commonly utilized by clinicians to provide local analgesia for minor acute knee joint musculoskeletal injuries during breaks in play or at halftime. Its effect on dynamic postural balance remains unclear. Objective: To investigate the acute effects of a 15-minute knee joint cryotherapy application on dynamic postural balance, as assessed primarily via a clinically oriented outcome measure. Design: Experimental study. Setting: University biomechanics laboratory. Patients or Participants: A total of 28 elite-level college male field-sport athletes. Intervention: Participants were tested on the anterior, posteromedial, and posterolateral reach directions of the Star Excursion Balance Test both before and after a 15-minute knee joint cryotherapy application. Main Outcome Measure(s): Normalized reach distances, 3-dimensional knee joint kinematics, sagittal plane hip and ankle joint kinematics, as well as fractal dimension of the center-of-pressure path during the performance of the anterior, posteromedial, and posterolateral reach directions of the Star Excursion Balance Test. Results: There was a statistically significant decrease in reach distance scores achieved on anterior, posteromedial, and posterolateral directions of the Star Excursion Balance Test from precryotherapy to postcryotherapy (P < .05). None of the decreases in reach distance scores exceeded the reported smallest detectable difference values. No significant differences were observed in hip, knee, or ankle joint kinematics (P > .05). No significant change in fractal dimension was observed for any reach direction following cryotherapy application (P > .05). Conclusions: The results of the present study indicate that dynamic postural balance is unlikely to be adversely affected immediately following cryotherapy application to the knee joint.

Context  Decreased postural stability is a primary risk factor for lower limb musculoskeletal injuries. During athletic competitions, cryotherapy may be applied during short breaks in play or during half-time; however, its effects on postural stability remain unclear. Objective  To investigate the acute effects of a 15-minute ankle-joint cryotherapy application on dynamic postural stability. Design  Controlled laboratory study. Setting  University biomechanics laboratory. Patients or Other Participants  A total of 29 elite-level collegiate male field-sport athletes (age = 20.8 ± 1.12 years, height = 1.80 ± 0.06 m, mass = 81.89 ± 8.59 kg) participated. Intervention(s)  Participants were tested on the anterior (ANT), posterolateral (PL), and posteromedial (PM) reach directions of the Star Excursion Balance Test before and after a 15-minute ankle-joint cryotherapy application. Main Outcome Measure(s)  Normalized reach distances; sagittal-plane kinematics of the hip, knee, and ankle joints; and associated mean velocity of the center-of-pressure path during performance of the ANT, PL, and PM reach directions of the Star Excursion Balance Test. Results  We observed a decrease in reach-distance scores for the ANT, PL, and PM reach directions from precryotherapy to postcryotherapy (P &lt; .05). No differences were observed in hip-, knee-, or ankle-joint sagittal-plane kinematics (P &gt; .05). We noted a decrease in mean velocity of the center-of-pressure path from precryotherapy to postcryotherapy (P &lt; .05) in all reach directions. Conclusions  Dynamic postural stability was adversely affected immediately after cryotherapy to the ankle joint.

The Star Excursion Balance Test (SEBT) is a valid and reliable measure of dynamic postural control. Center of pressure (COP) behavior during the SEBT could provide additional information about direction-dependent SEBT balance strategies. The purpose of this study was to quantify spatiotemporal COP differences using COP area and velocity among three different SEBT reach directions (anterior, posteromedial, posterolateral). The anterior direction COP velocity was significantly lower than both posterior directions. However, the anterior COP area was significantly greater than posterior. Based on COP behavior, the anterior and posterior reach directions appear to use different postural control strategies on the SEBT.

Abstract This study aims to identify if there is a relation between postural balance and the accuracy of 7 meters throws in handball. There is an increase need to improve the success of the 7 meters throw, due to its impact regarding a win or loss over the past years during high-end competitions. Subjects: 173 subjects were involved in this study, 123 males and 50 females with the ages between 18 and 21 years old. Materials: We’ve conducted the balance test using the AMTI NETforce BP 400600 force platform and for the accuracy test we’ve conducted a shooting trial that quantified the spread of a series of throws from the 7 meters mark. We’ve observed the radial dislocation, area and length of the center of pressure for the balance test and for the shooting trial we’ve measured the distance of the throw from a preset spot. Results: There were no correlation between the important factors of balance like Dislocation, Area, Length, and throwing percentage for the Circle, Area 1, Area 2, Missed balls. Instead, between the 3 important factors of balance, there are strong and positive correlations, drawing the conclusion that when we have big numbers for center of gravity deviations, total trajectory (cm2) and the area values, the chances to score a goal from 7 meters are lower. Conclusions: The results of the study confirm the hypothesis. The objectives for a future study is to find ways/methods to improve the general balance, in order to increase the efficiency for the 7 meters throwing.

Aims: To compare the postactivation potentiation effects of isometric contraction until failure in double- and single-leg tasks on older women’s balance. Methods: The one-legged balance test was performed before and immediately after a rise-to-toes task until the task failure. Older women were divided into two groups: a group performed the task with double leg (n = 43) and the other group with single-leg support (n = 55). Results: The single-leg group showed slower velocity of sway post rise-to-toes task (pre = 4.02 ± 1; post = 3.78 ± 1.15 m/s; p = .04) without differences for the center of pressure path length (pre = 79 ± 21; post = 75 ± 23 cm; p = .08). In the double-leg group, faster velocity of sway (pre = 4 ± 1.22; post = 4.25 ± 1.13; p = .03) and increased center of pressure path length (pre = 80 ± 24; post = 85 ± 23 cm; p = .03) were observed after the task. Conclusions: The single-leg group showed improved balance outcomes due to postactivation potentiation, while the double-leg group showed worsened balance consistent with muscle fatigue.

Background and Aims: Genu Varum is an angular deformity of the knee that is responsible for the alteration of the forces at the knee so that the line of force shifts farther medially from the knee joint centre intensifying the medial compartment load and creating a medial joint reaction force that is nearly three and a half times that of the lateral compartment. Football is a high intensity sport that places inordinate amounts of load and torque on the knee joint making it more susceptible to growth deformities in the developing age groups. Genu varum is a predisposing factor to lateral instability which affects dynamic balance. This study consists of a comparison in dynamic balance between professional football players, those without a knee deformity and those with genu varum deformity using the Star excursion balance test. Methodology: A comparative study was conducted among 40 elite level football players and they were divided into two groups one of which consisted football players without a knee deformity and the other group which comprised of football players with genu varum. Genu varum was calculated using the intercondylar distance measure. Star excursion balance test was used to assess dynamic balance of each individual and their average distances were calculated for each direction in the test. Results: The Reach Distances in the anterior direction showed no significant difference (P>0.05) between the control and Group Bs whereas significant differences (P<0.05) were obtained in the Posteromedial and Posterolateral directions. Conclusion: There was no significant difference in reach distances in the anterior direction but significant differences in the reach distances were observed in the posteromedial as well as the posterolateral direction suggesting that genu varum deformity does affect the dynamic balance in elite level football players. Key words: Genu Varum, Football Players, Dynamic Balance, Star excursion balance test.

Differentiating scans without evidence of dopaminergic deficits (SWEDDs) from Parkinson’s disease (PD) is very important to avoid costly and inappropriate interventions. The postural balance strategy patients with SWEDDs are not clear. This study investigates the difference in static postural balance between patients with SWEDDs and PD. Twenty-two patients (11 SWEDDs and 11 PD groups) and 11 control groups were instructed to quietly stand on a custom-made force platform. The outcome measures were, mean distance, 95% confidence ellipse area, mean velocity, mean frequency, peak frequency and peak power derived from the center of pressure (COP) data in overall, medio-lateral (ML) and anterio-posterior (AP) directions. As statistical analysis, ANOVA and post hoc tests were conducted for comparison of patients with SWEDDs and PD. SWEDDs patients presented a smaller postural sway size and a more frequent postural sway mainly in the ML direction ([Formula: see text]). On the contrary, there were no significant differences in mean velocity and peak power. Also, no significant differences existed between SWEDDs and normal subjects ([Formula: see text]). The results reflect that a few COP-based outcome variables might be useful to distinguish SWEDDs patients from PD patients. This study suggests that a static postural balance test can be used for clinical screening and identification of potential SWEDDs.

Current dynamic balance tests do not sufficiently test all aspects of balance required for dancers in everyday training and performances. The aim of this study was to examine alterations to the Star Excursion Balance Test (SEBT) to ensure a more dance-specific protocol. Twenty-four healthy ballet and contemporary dancers (age: 22.21 ± 6.47 years) participated in completing five different variations of the SEBT. This research implemented upper-body restrictions commonly used in dance settings and tested the effects of two different foot positions, parallel and turned out, as well as two alternate balance surfaces, a foam balance pad and a firm yoga block. Reach distances (percent of limb length), center of pressure (COP, cm2), error scores, and time to completion were measured. Overall, the dance-specific upper body restrictions did not affect the dancer’s ability to reach maximally and achieve a successful trial as there were no significant differences between the original SEBT and the dance-specific SEBT parallel condition (p = 1.00). The foam and block conditions were found to be significantly more difficult due to lower reach distance values, higher COP values, and higher error score values when compared to the original, parallel, and turnout positions (p < 0.05). Lastly, it was discovered that 62.61% of all errors made were in the crossed side and crossed front spokes, suggesting these are the most difficult reach directions to accomplish. The variations used in the study will aid in developing a reliable dance-specific dynamic balance test.

History Of

In assessing the foot types and lower limb injuries of elite netball players, the following summary seems warranted. Ninety percent of elite female netball players had symmetrical foot types for both feet and these players had experienced at least one lower limb injury. Only 7.6% players (N = 16) of the 204 players surveyed had never sustained a lower limb injury during their netball careers. Regardless of foot type, the injury history of these elite netball players presented with a total number of 449 injuries that occurred to both ankle joints (36%), one ankle joint (16%), both knee joints (6%), one knee joint (13%), shin soreness (18%), and retropatellar pain problems (11%). On further inspection, 55% of players experienced one to two lower limb injuries throughout their netball careers. Injured players showed that players with the pronating foot types with rearfoot abnormalities (57%) were the most commonly injured and that compensated rearfoot varus foot type presented the most lower limb injuries for all body sites.

The Impact

Injuries to the ankle joint in soccer athletes are extremely common. Twenty-two female collegiate soccer athletes performed ankle corrective exercises for 3 months to attempt to establish and maintain optimal ankle joint function. The corrective exercises were devised to improve ankle range of motion (ROM) and Star-Excursion Balance Test (SEBT) scores. Statistically significant improvements were seen in ankle ROM and in the SEBT for the posteromedial, posterolateral, and composite reach portions of the test; the anterior reach direction failed to show significant changes. These results have clinical implications which suggest that corrective exercises may promote optimal ankle joint function and potentially reduce the risk of injury to the ankle.
