Category: Ankle, Sports Introduction/Purpose: To compare proprioception, postural stability, and neuromuscular control between patients with mechanical laxity and recurrent ankle sprain. Methods: Among 86 patients with ankle instability, 45 patients had mechanical laxity (mean age 27.2 ± 7.0 years) and 41 had recurrent ankle sprain (mean age 25.1 ± 9.2 years). Both the affected and unaffected ankles of each patient were evalu- ated. Proprioception and neuromuscular control tests were conducted using an isokinetic machine, and postural stability was tested using a postural stabilometry system. Results: Proprioception was not significantly different between the unaffected or affected ankles of the mechanical laxity group compared with those of the recurrent ankle sprain group (n.s). Static and dynamic postural stability and neuromus- cular control were similar in the affected ankles between the two groups (n.s). However, postural stability (static, overall: p = 0.009, anterior– posterior: p = 0.028, medial–lateral: p = 0.022; dynamic, overall: p = 0.012, anterior–posterior: p = 0.004, medial–lateral: p = 0.001) and neuromuscular control (inversion: p = 0.031, eversion: p = 0.039, dorsiflexion: p = 0.029, plantarflexion: p = 0.035) were significantly decreased in the unaffected ankles of the recurrent ankle sprain group compared with those of the mechanical laxity group. Conclusion: The unaffected ankles of the recurrent ankle sprain group showed significant decreases in both postural stability and neuromuscular control compared with the mechanical laxity group. Clinicians and therapists should consider unaffected ankle rehabilitation in patients with recurrent ankle sprain to prevent future sprain events.

Chronic ankle instability is a common complication of ankle sprain. The clinical assessment of ankle instability is usually incomplete and difficult to interpret. Recently, more attention has been paid to the value of the anterior drawer test of the ankle. We assessed the accuracy of a modification of the anterior drawer test, comparing it with radiological stress view of the ankle in 25 patients with recurrent ankle sprain. The radiological examinations were performed by a TELOS instrument and included lateral and anteroposterior stress views. We found that the modified anterior drawer test correlated with the posterior opening of the tibiotalar joint and with the lateral tilt of the talus. We conclude that a slightly positive modified anterior drawer test may indicate injury to the anterior talofibular ligament. A significant movement of the ankle elicited by the modified anterior drawer test may indicate combined injury to anterior talofibular and calcaneofibular ligaments.

Landing from jumps is one of the main causes of injury within dance. A number of studies have reported a negative effect of shoe midsole thickness on lower limb kinematics during running due to the reduction in afferent sensory outputs from the foot’s epithelium. The purpose of this study was to examine the influence of varying midsole thicknesses in dance shoes on dynamic postural stability during a single-leg landing. Twenty-eight female undergraduate dance participants volunteered for the study. They carried out three trials under four conditions: barefoot and in ballet flats (2 mm midsole thickness), jazz shoes (7 mm), and dance sneakers (30 mm). The task consisted of a single-leg forward jump over a hurdle at 50% of their maximal vertical jump height, landing on a force platform, and balancing for 3 seconds. The stability indices for vertical stability (VSI), anterior-posterior stability (APSI), medial-lateral stability (MLSI), and dynamic postural stability (DPSI) were calculated using Wikstrom’s revised method. Significant differences were reported between the midsole thicknesses for both DPSI and VSI (p<0.01). No statistical differences were noted for the indices SPSI or MLSI. The present data agree with the running studies in that increased midsole thickness has a negative influence on landing stability.

OBJECTIVES To determine the effectiveness of K-tape on dynamic postural stability of the injured limb in adolescent athletes with chronic ankle instability (CAI) by measuring reach distance with the modified Star Excursion Balance Test (mSEBT).METHODS Twenty volunteers (20 females [17.78 ± 1.22 yrs], height [163.89 ± 7.69 cm], mass [62.51 ± 9.81 kg]) with CAI. Four strips of K-tape were applied to the injured limb. Participants completed 4 trials of testing (2 with tape, 2 without tape) using the mSEBT as the assessment tool. We applied 4 strips of K-tape to the injured limb and then tested postural stability using the mSEBT to see if there was an increase of reach distance in the mSEBT. Measuring reach distance in Anterior (AN), Posteromedial (PM), Posterolateral (PL) on the injured limb with K-tape and without K-tape condition. We measured the reach distances and then normalized the distance to account for height differences. A repeated measures t-test was used for this study.RESULTS There is no statistically significant different between the condition with K-tape and without K-tape in the reach distances on the mSEBT in adolescent athletes with CAI.CONCLUSIONS Based on the results, there appears to be no improvement of reach distance using the mSEBT in adolescent athletes with CAI. Therefore, clinicians need their thoughtful consideration for applying K-tape to improve dynamic postural stability in adolescent athletes with CAI.

Abstract Background Ankle sprain is one of the most common musculoskeletal injuries in sports, at work, and at home. Subjects who suffer from this injury may develop ankle instability. Functional instability has been associated with a high rate of resprain and impaired neuromuscular control in patients with ankle instability. Objective Measurement of neural and muscular mechanosensitivity after ankle sprain injury and establishment of the relationship between these variables. Methods A cross-sectional case-control study was performed with a sample of 58 students from Alcalá de Henares University (21 males and 37 females, mean age ± SD = 21 ± 3.7 years). Subjects were divided into two groups: a case group (N = 29, subjects with unstable ankle) and a control group (N = 29, healthy subjects). The pressure pain threshold (PPT) of the tibialis anterior, peroneus longus, and peroneus brevis muscles and mechanosensitivity of the common peroneus and tibial nerves were evaluated in all subjects through a manual mechanical algometer. Results Neuromuscular PPTs showed significant differences (P &lt; 0.05) between both groups, such that, compared with the control group, the case group exhibited significantly lower PPT levels. In the case group, a strong positive correlation was observed between neural and muscular homolateral mechanosensitivity in both lower limbs. Conclusions Participants with chronic ankle instability showed higher neuromuscular mechanosensitivity in muscles and nerves surrounding the ankle joint than healthy subjects. These findings indicate that low PPT values may be associated with symptoms that characterize this disease.
