“…For sedentary individuals, daily activities of the lower body mostly include walking, stair climbing, and sit-to-stand movements. During these cyclic movements, it has been well documented that both the dominant and the nondominant legs are used synchronously and, thus, quite possibly contributed the same amount to the generation of movements (21). On the other hand, overuse of one leg over another for certain athletic activities, such as shooting in soccer or kicks in combat sports, develops limb asymmetries in the athletic population.…”

Objective: The primary purpose of the present study was to examine differences in balance performance between the dominant and nondominant legs during dynamic balance tasks in healthy individuals with no regular exercise backgrounds. As a secondary purpose, gender differences in single-leg stance were also investigated. Material and Methods: Twenty-one men and 24 women participated in this study. Single-leg balance performance was evaluated by the Biodex Stability System SD. All subjects were tested at level 1 for 20 sec, and 1-minute rest intervals were provided among 6 trials for each leg. Results: According to the results, there was no multivariate effect of leg dominance on any stability index, indicating symmetry between limbs in terms of balance performance. Mean comparisons showed that women had significantly better balance scores than men on overall (p<0.05), antero-posterior (p<0.05), and medio-lateral (p<0.05) stability indexes. Conclusion: Functional symmetry exists between the dominant and nondominant leg in all stability indexes of balance performance of sedentary individuals. Female subjects swayed less than males on both the dominant and the nondominant leg measurements in all directions (overall, antero-posterior, and medio-lateral directions).

“…23 Additionally, it has been shown that an imbalance in H/Q peak torque strength balance ratio correlates with a greater incidence of lower extremity injury, including anterior cruciate ligament (ACL) injuries. 19 In addition, it has been suggested that muscular weakness and bilateral lower limb muscular strength deficits affect posture, 24 sports performance, 25 and increases hamstring strain rate. 17,26 Thereby, in order to screen H/Q strength ratio and bilateral symmetry, it is common to assess athletes in the beginning of the season.…”

Background: Anterior cruciate ligament injury is higher in soccer athletes as compared to athletes of other sports. Risk factors for anterior cruciate ligament injury include low knee hamstring/quadriceps strength ratio and bilateral strength deficits. Purpose:To investigate isokinetic thigh muscles strength, hamstring/quadriceps strength ratio, and bilateral strength comparisons in athletes who participate in professional soccer, futsal, and beach soccer.Study Design: Cross-sectional study.Methods: Brazilian professional soccer (n=70), futsal (n=30), and beach soccer (n=12) players were isokinetically assessed to examine strength of knee extensors and flexors at 60 degrees/second in concentric mode, to measure peak torque of dominant and non-dominant limbs. Results:In the dominant limb, for extensors muscles, futsal players presented significantly lower peak torque values (223.9±33.4 Nm) than soccer (250.9±43.0 Nm; p=0.02) and beach soccer players (253.1±32.4 Nm; p=0.03). Peak torque for extensor muscles in the non-dominant limb was significantly lower in futsal (224.0±35.8 Nm) than in beach soccer players (256.8±39.8 Nm; p=0.03). Hamstring/quadriceps strength ratio for dominant limbs for futsal (57.6±10.1%), soccer (53.5±8.8%), and beach soccer (56.3±8.4%) players presented no significant differences between groups; however, the mean values were lower than recommended values found in the literature. There were no strength deficits for any of the evaluated groups when compared bilaterally. Conclusions:Futsal athletes presented lower values for quadriceps strength than soccer and beach soccer athletes. Futsal, soccer, and beach soccer players presented no strength asymmetries, but they presented with strength imbalance in hamstring/quadriceps strength ratio. Level of Evidence: 3

“…It has the advantage of being light, portable, easy to operate, and relatively inexpensive [10][11][12][13] , and it can be applied in occupational 2 and clinical environments [14][15][16][17] . Other advantages are: the recording is not influenced by other devices or energy sources, large quantities of data can be recorded, and long duration recordings can be made 13,18 .…”

| Background: The recording of human movement is an essential requirement for biomechanical, clinical, and occupational analysis, allowing assessment of postural variation, occupational risks, and preventive programs in physical therapy and rehabilitation. The flexible electrogoniometer (EGM), considered a reliable and accurate device, is used for dynamic recordings of different joints. Despite these advantages, the EGM is susceptible to measurement errors, known as crosstalk. There are two known types of crosstalk: crosstalk due to sensor rotation and inherent crosstalk. Correction procedures have been proposed to correct these errors; however no study has used both procedures in clinical measures for wrist movements with the aim to optimize the correction. Objective: To evaluate the effects of mathematical correction procedures on: 1) crosstalk due to forearm rotation, 2) inherent sensor crosstalk; and 3) the combination of these two procedures. Method: 43 healthy subjects had their maximum range of motion of wrist flexion/ extension and ulnar/radials deviation recorded by EGM. The results were analyzed descriptively, and procedures were compared by differences. Results: There was no significant difference in measurements before and after the application of correction procedures (P≤0.05). Furthermore, the differences between the correction procedures were less than 5° in most cases, having little impact on the measurements. Conclusions: Considering the time-consuming data analysis, the specific technical knowledge involved, and the inefficient results, the correction procedures are not recommended for wrist recordings by EGM.Keywords: reproducibility of results; physical therapy; health evaluation.
