RESUMO
OBJECTIVE: To evaluate the effects of silicone ankle sleeves (SASs) and lace-up ankle braces (LABs) on neuromuscular control, net joint torques, and cutting agility in healthy, active individuals. DESIGN: Markerless motion-capture technology tracked subjects fitted with SASs, LABs, or no brace while they performed the movements: Y-excursion, left cutting, right cutting, single-leg drop vertical jump (SLDVJ), 45-degree bound, and single-leg squat (SLS). SETTING: University Laboratory. PARTICIPANTS: Ten healthy, active individuals (5 males and 5 females, mean ± SD 23.60 ± 1.43 years of age). MAIN OUTCOME MEASURES: Degrees of joint range of motion (ROM), Newton-meters of joint torque, time to perform a cutting maneuver. RESULTS: SASs and LABs resulted in significantly different knee and ankle ROM and hip internal rotation in the SLDVJ, SLS, Y-excursion, cutting maneuver, and 45-degree bound when compared to control (p < .05). Both ankle and knee torque were significantly reduced in the 45-degree bound and cutting movements with both types of PABs (p < .05). There were minimal differences between the SASs and LABs for all conditions. There were no statistically significant differences in cutting times for any of the 3 conditions. CONCLUSION: Both SAS and LAB positively impacted neuromuscular control, reduced net joint torque, and neither impaired cutting agility when compared to control.
RESUMO
Closed traumatic Achilles tendon rupture is a common injury, especially in the aging athlete. Traditionally open repair has been recognized to offer a lower rerupture rate compared with nonoperative methods but with a higher complication rate. Percutaneous repair has been described to offer the benefits of open repair while avoiding the complications. The sural nerve is potentially susceptible to injury, and specialized instrumentation has been developed to avoid this event. This article discusses several techniques of minimally invasive Achilles tendon repair. Many authors have evaluated these techniques and the results are discussed here.
