Book excerpt: BACKGROUND: Ankle sprains are the most common injuries among physically active people, with 40-70% developing functional ankle instability (FAI), characterized by frequent episodes of "giving way" and sensations of joint instability. Kinesio Taping, ® an intervention that has recently gained popularity may help decrease postural control deficits related to FAI. This study examined the immediate and prolonged effects of Kinesio Taping® on postural control in subjects with FAI and investigated differences between healthy, coper, and unstable ankles as measured through single-limb balance on a forceplate. METHODS: Sixty physically active, college-aged participants (height: 172.5 ± 9.7 cm, mass: 74.2 ± 16.2 kg, age: 21.5 ± 2.6 years) were sorted into three separate groups: healthy control, copers, and FAI. Subjects were stratified using the Cumberland Ankle Instability Tool (CAIT) combined with their history of ankle injury. Dependent variables were time to boundary (TTB) measures and traditional center of pressure (COP) measures in both the mediolateral (frontal) and anteroposterior (sagittal) planes. Testing was performed at baseline, immediately after application of the tape, 24 hours post-tape application, and immediately after removal of the tape. RESULTS: Significant group main effects for COP standard deviation (F2,57 = 4.309, p = 0.018) and range (F2,57 = 4.918, p = 0.011) in the sagittal plane were noted. Significant condition main effects for TTB absolute minima (frontal plane, F 3,159 = 1.607, p = 0.015) and standard deviation (frontal, F3,138 = 5.710, p = 0.002 and sagittal plane, F3,141 = 0.889, p = 0.029) were also noted. Post hoc testing revealed decreased COP standard deviation and range for the ankle instability group compared to controls and significant improvements at 24 hours post-tape in all groups for TTB absolute minima (p = 0.025) and standard deviation (frontal plane, p = 0.002). CONCLUSIONS: Deficits in COP variables were seen in unstable ankles as compared to both healthy ankles and copers. Minor improvements in TTB measures after 24 hours of continuous wear of Kinesio® tape were observed in healthy, coper, and unstable ankles. Since between group differences were seen in COP measures, but improvements post-tape application were seen only in TTB variables, we can conclude that Kinesio® tape did not improve the specific postural control deficits experienced by unstable ankles. Therefore, while Kinesio® tape may provide a small benefit to postural control at the ankle, it does not appear to be effective at improving ankle instability deficits. Keywords: balance, time to boundary, center of pressure.

Available in PDF, EPUB and Kindle. Book excerpt: In dance, injuries are extremely common and stem from the repeated jumping and leaping tasks found within performances. Fatigue is thought to be related to an increased risk of injury due to altered movement patterns, but little research has examined the effects of fatigue on dance performance. The purpose of this study is to determine the effects of a dance-specific fatigue protocol on performance of a sauté jump. It was hypothesized that (1) ankle dorsiflexion would decrease, (2) ankle plantarflexion would increase, (3) ankle eversion would decrease, (4) vertical ground reaction force (vGRF) would increase, (5) propulsive ground reaction (pGRF) force would increase, and (6) braking ground reaction force (bGRF) would decrease when dancers are in a fatigued state. Twenty healthy, experienced dancers (mean age 24.9±5.5 years, height 1.6± 0.05m, and mass 58.3±4.5 kg) with 19.6±5.7 years of dance training participated in this study after providing written informed consent. Dancers completed 10 sauté jumps before and after a dance-specific fatigue protocol designed to mimic a ballet class or rehearsal; the protocol was approximately one minute long and included a combination of jumps, leaps, and turns. Fatigue was defined as each dancer reaching a self-reported rating of greater than or equal to 17 on the Borg Rating of Perceived Exertion scale. A 12-camera motion capture system and two force plates were utilized to collect three-dimensional kinematic and kinetic data during the protocol. (1) Peak ankle dorsiflexion, (2) peak ankle plantarflexion, (3) peak ankle eversion, (4) peak vGRF, (5) peak pGRF, and (6) peak bGRF data were extracted for further analyses. Repeated measures MANOVAs were utilized with the Bonferroni alpha threshold of significance at less than 0.05. There were statistically significant differences from pre- to post-fatigue with (1) peak right dorsiflexion increased, (2) peak right plantarflexion decreased, (3) peak right eversion increased, and (4) peak vGRF decreased after fatigue. There was no change in (5) peak pGRF or (6) bGRF. The results revealed that aesthetics during a dance performance are affected by fatigue. The reduction of eccentric lower extremity muscular control may play a vital role for these dancers in terms of kinematic and kinetic changes after fatigue. With jump landing kinematics and kinetics affected after only an average of five minutes of dancing, these dancers may benefit from developing more eccentric strength to allow them to slow down properly while landing and to sustain the aesthetic demands throughout the performance. Having better control of one's body while landing from any jump can aid in preventing poor landing mechanics and potential injuries.

This book was released on 2014 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: "High risk neuromuscular control strategies during landing and cutting maneuvers are thought to be a major contributing factor to the 6 times greater risk of ACL injury in female athletes compared to male athletes. However, female dancers who have similar fitness capabilities and perform many of the same cutting and landing tasks as female athletes are less likely to display high risk neuromuscular strategies, have similar neuromuscular control strategies as male dancers, and are 3- 5 times less likely to suffer an ACL injury compared to female athletes. While multiple theories have been proposed to explain this protection in female dancers, preliminary research suggests female dancers may adopt a more protective neuromuscular control strategies as a result of their training practices. Therefore, the primary objective of this study was to comprehensively compare neuromuscular control strategies in collegiate female dancers and collegiate female field athletes to determine if female dancers demonstrate more protective neuromuscular control patterns during functional tasks as characterized by 1) decreased vertical ground reaction forces (vGRF), 2) quicker stabilization of the anterior-posterior and medial-lateral ground reaction force, 3) smaller distance between center of mass (COM) and location of center of pressure (COP), 4) decreased knee valgus, 5) increased ankle plantar flexion, 6) decreased knee extensor moment, and 7) quicker muscular activation. Forty collegiate females, 20 dancers (age= 20.4 ± 1.9 yrs, height= 164.8 ± 6.1 cm, weight= 63.5 ± 8.8kg, experience= 14.3 ± 3.9 yrs) and 20 athletes (age= 19.4± .9 yrs, height= 169.3 ± 7.1 cm, weight= 69.8 ± 13.0 kg, experience= 12.2 ± 2.9 yrs) matched on year of experience were measured for postural control during a dynamic forward hop stabilization task; hip, knee and ankle joint neuromechanics during a planned double leg drop landing; and reflex response characteristics during an unplanned lower extremity perturbation. Results revealed no significant differences between female athletes and dancers on muscle reflex time following a functional perturbation or in their time to stabilization during the dynamic balance test. During the drop jump landing, dancers versus athletes landed with lower vGRF [F (3, 33) = 3.44, p = .03, ES = .24], position their COM more anteriorly [F (1,38) = 4.8, p=.03], moved through a greater sagittal plane ROM [F (3, 36) = 4.6, p=.008] primarily driven by greater ankle joint excursion, and move through equal frontal plane motion at the hip and knee [F (2, 37) = 1.6 p=.23, Partial Eta Squared ()=.08]. The greater sagittal plane excursions values were largely a product of a more extended posture at ground contact and did not result in larger peak values. These findings suggest that dancers and athletes may have similar abilities to respond to postural perturbations, but that female dancers may demonstrate some elements of more protective neuromuscular control strategies during planned movements as a result of their training practices. Investigation of dance training may assist in the development of more protective strategies in dancers and inform our future prevention efforts in female athletics."--Abstract from author supplied metadata.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Functional ankle instability (FAI) is characterized by the recurrent giving way of the ankle and the constant feeling of instability that affects the quality of life of its patients adversely. Kinesiology Tape (KT), differed from the traditional rigid athletic tape, becomes more popular as a new therapeutic tool for injuries management. It is reported to decrease pain, promote blood circulation and natural healing of muscular functioning. However, scientific evidence of KT's effects on FAI remains very limited. Therefore, the purpose of the present study was to investigate if applying KT on the unstable ankle may improve static postural control in individuals with FAI. Twenty young adults with FAI performed a series of static quiet bipedal and unipedal stances on a force platform. Postural control was assessed by four measures derived from the centre of pressure (COP) data: 95% Confidence ellipse of total displacements (area), standard deviation of displacements (SD), mean velocity and mean power frequency (MPF). Measurements were taken at three different times: baseline or no tape, immediately after the application of KT on the unstable ankle, and 24 hours after the taping application with the tape remaining on the ankle. Results revealed only minor changes in mean velocity and MPF in unipedal stances immediately after KT application. However, the overall results indicated statistically insignificant improvements in postural control performance neither immediately after KT application nor after 24 hours. In conclusion, our results suggest that the use of KT did not affect bipedal and unipedal stances of individuals with functional ankle instability.
Download or read book Multi segmental Postural Coordination in Professional Ballet Dancers written by Adam W. Kiefer and published by . This book was released on 2009 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Postural control typically must be coordinated in a way that is functional with regard to the control of ulterior actions. This entails the formation of coordinative structures that are appropriately flexible and, in general, the incorporation of contributions from the vestibular, visual, and proprioceptive systems. Ballet dancers are known to exhibit heightened proprioceptive awareness and enhanced levels of postural control. However, it is not known if these are related, and the coordination of dancers' body segments during balance has never been examined. The present study utilized a visual tracking task in which participants tracked the fore-aft motion of a virtual target, by standing on one leg and swaying so as to maintain an equal distance between their head and the target at all times, at frequencies of 0.20 and 0.60 Hz. Mean and SD relative phase between the ankle and hip joints were used to index coordination stability during task performance. Coordination stability during this task is generally believed to depend on proprioceptive coupling of rhythmic excursions about the ankle and hip. A joint-position matching task was used to assess proprioceptive awareness for the ankle, knee, and hip joints of both legs. An eyes-closed, quiet-standing task was also employed. Results showed that the dancers exhibited greater proprioceptive awareness in their lower limbs, and were also less variable in their ankle-hip coordination during the dynamic postural coordination task. Additionally, dancers exhibited lower determinism in the coupling between ankle and hip oscillations than controls. These results demonstrate that dancers are more sensitive to proprioceptive information in their lower limbs, and this may be an underlying mechanism driving their increased coordination stability. Dancers, through training and experience, may have become proficient at optimizing the constraints that enable them to perform complex balance tasks.

Available in PDF, EPUB and Kindle. Book excerpt: Background. Lateral ankle sprains are the most common type of injury in the sporting world accounting for approximately 30% of all injuries. Kinesiology tape is an innovative adhesive tape with elastic properties that allow the user to gain a greater sense of feel at the application point without restricting mobility. This “proprioceptive” feeling induced by the application of the tape can help to improve stability while simultaneously rehabilitating the joint applied. This can be useful in both preventing injury and stimulating repair of the joint. Objective. The purpose of this study was to examine the effects of kinesiology tape application on lateral ankle instability using the Neurocom SMART Balance Master System (Neurocom)
Download or read book The Effects of Fatigue on Lower Extremity Landing Mechanics in Dancers written by Rachel Abergel and published by . This book was released on 2019 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction: Dancers use mechanical manipulation of the body to convey a detailed story in an aesthetic manner. In doing so, both acute and chronic fatigue as a result of countless rehearsals and performances are to be expected. During landing in particular, joints of the lower extremity are constantly loaded which may result in adverse kinetic and kinematic outcomes. There is limited dance research looking at lower extremity kinematics in conjunction with fatigue, and even more limited research offering insight into dance-specific fatigue protocols. The purpose of this study was to compare sauté landings before and after fatigue in experienced female dancers. Methods: Twenty experienced dancers (mean age 24.9 ± 5.5 years; height 1.6 ± 0.1 m; weight 58.3 ± 4.5 kg; 20.1 ± 5.7 years dance training) participated after providing informed consent. A ballet-based movement protocol was created to generate a self-reported fatigue response in dancers. The Borg Scale for Rating of Perceived Exertion (RPE) was used to classify fatigue as a rating of ≥17. A 12-camera motion capture system was used to collect three-dimensional kinematic data as dancers performed 20 sauté jumps before and after fatigue. Data were extracted to compare peak hip and knee kinematics before and after fatigue using a MANOVA (p≤0.05). Intersegmental coupling of the knee and hip were measured by amount of time spent in each phase (Anti-Phase, In-Phase, Knee Phase, Hip Phase) in the sagittal, frontal, and transverse planes following fatigue conditions in jump landings. Coupling angles included time spent in each phase during a jump cycle. Results: After fatigue, dancers demonstrated increased hip flexion (36.01±8.34° pre, 40.76±10.26° post; p=0.004) and knee flexion (62.74±3.78° pre, 65.31±4.66° post; p=0.002) during sauté landings. Dancers also demonstrated decreased peak hip external rotation (-15.64±6.66° pre, -13.41±6.17° post; p=0.008) and increased knee abduction (5.86±2.44° pre, 6.64±2.98° post; p=0.015) when fatigued. Coordination coupling showed statistically significant increases in time spent In-Phase in the hip and knee bilaterally in the sagittal plane following fatigue (41.95 ± 14.08 pre, 50.4 ± 14.28 post, p = 0.003 left leg; 42.05 ± 13.35 pre, 49.45 ± 14.05 post, p = 0.007 right leg). There was also significantly less time spent in Knee Phase in the hip and knee coupling, bilaterally following conditions of fatigue (41.7 ± 15.96 pre, 33.65 ± 14.21 post, p = 0.001 left leg; 41.65 ± 13.36 pre, 34.25 ± 14.22 post, p = 0.004 right leg). Conclusion: As fatigue ensues, both hip and knee mechanics are significantly altered. In the sagittal plane, both the hip and knee demonstrate increased flexion during landing in the fatigued state. Additionally, the knee goes into a greater amount of abduction after fatigue and decreased external rotation at the hip accompanies further flexion. These altered landing mechanics put the body into a less desirable anatomical and aesthetic position. A possible link can be made to the change in these variables and how they may lead to injurious outcomes. Keywords: fatigue; dance; rating of perceived exertion; kinematics; lower extremity; injury
