简要总结
Background: Lateral ankle sprain (LAS) is a very common injury in the general population and in the world of basketball in particular, initially Its recurrence rate is very high, generating chronic ankle instability (CAI), accompanied by decreased muscle activation in the ankle musculature and lack of motor control. The aim of this study is to evaluate the activation of the peroneal musculature during the sports gestures of layup and free throw, and the motor control of both in healthy patients and in patients with CAI.
Method: Using a surface electromyography study (sEMG) of 58 basketball players of amateur teams, 36 women and 22 men, with and without CAI, in the peroneus lateralis longus (PLL) and peroneus lateralis brevis musculature (PLB).
详细描述
Design A case-control study was conducted. The entire procedure was carried out for human experimentation. The case control study followed the CONSORT guidelines.
Meassurement Muscle activity was recorded using an mDurance R surface EMG system (mDurance Solutions SL, Granada, Spain), a portable sEMG system that consists of three parts(i) A Shimmer3 EMG unit (Realtime Technologies Ltd., Dublin, Ireland), which is a bipolar sEMG sensor for muscle activity acquisition. Each Shimmer sensor is composed of two sEMG channels, with a sampling rate of 104 Hz. (ii) The mDurance mobile application (Android), which receives data from the Shimmer unit and sends it to a cloud service(iii) The mDurance cloud service, where the sEMG signals were stored, filtered and analysed, and reports were generated.
Surface electrode placement was performed following the recommendations of Surface EMG for Non-Invasive Muscle Assessment (SENIAM),bilaterally and parallel to the direction of the muscle fibres.
Protocol Firstly, anthropometric variables and personal information, training hours of the participants as well as ankle and lower limb injuries were collected through a Microsoft Forms.
In this study, changes in the sEMG signal of PLL and PLB in patients with and without CAI were investigated in the performance of various basketball-specific sport gestures . These changes in signal amplitude (root mean square) reflect the level of activation during the sporting gesture in the PLL and PLB muscles.

结局指标
主要结局
Measurement of the different activation patron of the peroneal muscles (electromyograpic analysis), in the different phases of the layup gesture , in patients with CAI and without CAI.
时间窗: Up to 28 weeks
As a primary outcome measure, the investigators evaluated the difference in the activation of the PLL and PLB muscles both in patients suffering from CAI and in those who do not suffer from it, during the development of the layup.
次要结局
- Evaluation of moment of greatest activation (electromyographic evaluation) of the peroneal muscles, and motor control in layup gesture, in patients with CAI and without CAI.(Up to 28 weeks)
