Extremity Injuries

Ankle injuries are common among young ballet dancers. These injuries may be attributed to ankle instability, insufficient lower extremity strength, and poor balance control. The purpose of this study was to explore whether these dancers exhibit functional ankle instability and if their single-leg balance control and lower extremity muscle strength correlate with functional ankle instability and leg injuries. Twenty-one ballet dancers (aged 10 to 17 years) participated in the study. The Cumberland Ankle Instability Tool (CAIT) questionnaire was used to examine functional ankle stability. Isometric muscle strength of the major lower extremity muscles was measured with a digital hand-held dynamometer. Single-leg balance was evaluated with the Y-Balance Test (YBT) and three Athletic Single-leg Stability Test (ASLST) protocols. Lower extremity injuries (self-reported) within 6 months after testing were recorded for correlation analyses. Both dominant and non-dominant ankles of the subjects exhibited functional ankle instability (26.71 and 25.71, respectively). Raising the center of mass (passé and first arm position) during the ASLST did not significantly affect balance performance (p = 0.104). However, removing extrinsic visual feedback significantly decreased single-leg balance (p < 0.001). In general, there was low correlation (r ≤ 0.49) between muscle strength, CAIT, YBT, and ASLST scores with lower extremity injuries. It is concluded that for young ballet dancers lower extremity muscle strength and single-leg balance control may not be strong contributing factors to leg injuries. This study also suggests that functional ankle stability may not have a direct impact on single-leg balance, and ballet dancers rely heavily on extrinsic visual feedback for single-leg balance control. Teachers might consider minimizing extrinsic feedback to challenge ballet dancers when implementing training protocols for single-leg balance control.

Background: Functional ankle instability (FAI) is a common consequence of ankle sprain injury, especially in high-impact sports. Objectives: To investigate the effect of six weeks of suspension training with total resistance exercises (TRX) on proprioception and muscle strength in female athletes with FAI. Methods: Thirty female athletes with FAI (age: 21.9 ± 2.2 years, height: 169.3 ± 4.2 cm, and weight: 59.8 ± 6.1 kg) were randomly assigned to two equally numbered groups: TRX training and controls based on inclusion and exclusion criteria. In the pre-test, the anthropometric variables and also proprioception accuracy and muscle strength of subjects were evaluated by joint angle reset test (JART) and manual muscle testing (MMT) in both dorsiflexion and plantarflexion motions. The training group completed three sessions per week with progressive load for six weeks, and each training session lasted 15 - 20 minutes, whilst control subjects continued with their normal activity without special sport activities. After six weeks of training, all tests performed in the pre-test phase were also performed in the post-test phase. The t-test was used for statistic analysis (α ≤ 0.05). Results: The findings showed that TRX training significantly improved the proprioception accuracy (P ≤ 0.001) and muscle strength (P ≤ 0.001) in the training group rather than the control group. No statistically significant difference was found in any of the tests between pre-test and post-test for the control group (P > 0.05). Conclusions: Six weeks of TRX suspension training had a positive effect on strength and proprioception accuracy in female athletes with FAI.

Abstract Background Functional ankle instability is a common musculoskeletal condition affecting the community. It is characterized by repetitive bouts of giving away, recurrent sprains, and sensation of instability leading to functional deficits in an individual. The present study aimed to assess the influence of kinesiophobia on physical function and quality of life in participants with functional ankle instability. A cross-sectional study was conducted in 30 participants with functional ankle instability. Kinesiophobia was assessed using the 17-item Tampa Scale of Kinesiophobia, physical function using the Foot and Ankle Ability Measure (FAAM) and the FAAM-Sport version (FAAM-S), and quality of life using SF-36. Results The TSK score showed a moderate negative correlation with FAAM-S (r = −0.5, p = 0.005) and a weak negative correlation with SF-36 physical component summary (r = −0.42, p = 0.02). However, TSK showed no significant correlation with FAAM-ADL and SF-36 mental component summary. Conclusion Increased fear of movement, reduced physical function, and health-related quality of life were observed in functional ankle instability individuals. Hence, evaluation of these parameters is imperative in these individuals.

Functional joint instability is common after joint soft tissue injuries. We present in this report our pilot finding in a study of functional ankle instability. Although past studies have suggested multiple pathological factors for functional ankle instability, none of those factors has been confirmed in the past studies. More importantly, no known factor can provide an explanation for an ankle giving way phenomenon which is a key element in defining a functional ankle instability. In this pilot study, we tested five subjects with functional ankle instability using a dynamic ankle stretching device combined with nociceptive electrical stimulation. Three out of five subjects showed a drastic reaction in which they totally gave up their control of upright standing after their affected ankles were under the combined ankle stretch and nociceptive stimuli. Such drastic reaction was not observed in the same ankles under only the ankle stretch. There was no such drastic reaction in the unaffected ankle under either testing condition. This pilot finding indicates a possibility of a hyper-reactivity to unloading reaction in the ankles with functional ankle instability
