Injury of Hip and ThighNCT04101786
Analysis of Different Hip Adductors Exercises
A study testing Hip adductors exercise variations in people with Injury of Hip and Thigh, run by University of Primorska at 1 site in Slovenia.
Trial summary
Groin injuries present a major problem in sports due to its high frequency, long-lasting symptoms and high risk of re-injury. The most common groin injury is the adductor strain (around two thirds of all groin injuries), while the biggest risk factors are previous injury and lower hip adductors strength.

About this study
Official title: Kinematic and Electromyographic Analysis of Different Hip Adductors Exercises
Groin injuries present a major problem in sports due to its high frequency, long-lasting symptoms and high risk of re-injury. The most common groin injury is the adductor strain (around two thirds of all groin injuries), while the biggest risk factors are previous injury and lower hip adductors strength. The purpose of this study is to present and biomechanically evaluate several new strengthening exercises targeting hip adductors. Exercises will be performed with the use of our novelty device, which enables eccentric strengthening of the hip adductors in different hip and knee positions. We hypothesize that performing modified hip adductors exercises using the novelty device could enable participants to perform hip adduction throughout larger ROM during eccentric contractions, while changing hip and/or knee angle will differently affect muscle activity and produced joint torques. The latter could be helpful for preventive or rehabilitative training for hip adductors strain injuries, in which therapists want to target specific hip adductor muscle.
Read the detailed description
Following the general warm-up (light aerobic activity, dynamic stretching exercises and bodyweight strength exercises), the electromyographic (EMG) sensors and kinematic markers will be attached to the participant, who will then perform the maximal voluntary contractions for the purpose of EMG normalization. Then the participant will perform new hip adductor exercises using the novelty device, which enables hip adduction eccentric contractions in different hip and knee positions. The latter is important when trying to target specific hip adductor muscle, since different hip and/or knee angles differently affect individual muscle activity and joint torques. Exercises will be performed in randomized order, while the EMG and kinematic signals will be synchronously captured. EMG muscle activity and joint torques, produced during the exercises, will be analysed. Descriptive statistics will be calculated and reported as mean ± standard deviation. Shapiro-Wilk test will be used for testing of normality and Levene's test for equality of variances. Differences among corresponding variables will be obtained from different exercises and tested with the analysis of the variance for repeated measurements. For pair-wise comparisons, paired 2-tailed post-hoc t-tests with Bonferroni's correction will be used. The level of statistical significance will be set at p < 0.05.
