Download or read book Relationship Between Lumbo pelvic hip Complex Muscle Activation and Lower Limb Biomechanics During Functional Tasks Before and After Fatigue written by Erika Zambarano and published by . This book was released on 2019 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knee injuries are extremely prevalent in the active populations. Many knee injuries share risk factors including increased knee valgus, increased hip adduction, and poor neuromuscular control. Due to the potential for long-term complications, a variety of injury prevention programs have been developed and many consider there is a breakdown occurring somewhere within the kinetic chain. The lumbo-pelvic-hip complex (LPHC) is the center of the kinetic chain and is responsible for force generation in athletic movement and so it is often targeted in such programs and in treatment. There is limited research evaluating the role of LPHC stability and the connection to the rest of the kinetic chain during sport related movements. There is also limited research looking at the effect fatigue has on the ability of the LPHC to stabilize in isolation and the effect it has on the biomechanics of the lower extremity during functional tasks. Therefore, the purpose of this study was to observe the effect of full body fatiguing exercise on the outcomes of a LPHC stability assessment and subsequent muscle activation and biomechanics during a single leg squat (SLS). A descriptive laboratory study was utilized with the independent variables being time (pre- and post-fatigue) and dependent variables being performance on a LPHC stability assessment, muscle activation of muscles of interest, and a frontal plane biomechanical assessment. Healthy, physically active adults were recruited for this study and completed baseline measures for an LPHC stability assessment and SLS, completed a fatiguing protocol, and then repeated the two tasks in a fatigued state. Results indicated a significant decrease in performance on the LPHC stability assessment and an increase in activation of the rectus abdominis muscle following fatigue. The rectus abdominis and internal oblique increased in activation during the SLS following fatigue, but the biomechanical measures experienced no significant changes during the task. In conclusion, full body fatigue negatively impacts the ability of the LPHC to stabilize in isolation. The muscle activity of the LPHC during a functional task is also altered; however, the impact this has on the quality of movement and biomechanics should be further investigated.

Hogg and published by . This book was released on 2018 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Functional valgus collapse (a combination of knee abduction and internal rotation and hip adduction and internal rotation) is a modifiable lower extremity movement pattern commonly associated with anterior cruciate ligament (ACL) injuries in females. Though the gluteus maximus and gluteus medius have frequently been named contributors to functional valgus collapse, evidence supporting their role in lower extremity movement has been inconsistent, and could in part be due to methodological differences between studies and the accepted practice of analyzing discrete variables instead of overall movement patterns. Better elucidation of gluteal muscle influence on lower extremity biomechanics may be a critical step for the reduction of ACL injury rates, as neuromuscular dysfunction is likely more responsive to injury prevention efforts than are other risk factors such as bony anatomy, ligament quality, or hormonal influences, that are more difficult to modify. Therefore, the purpose of this study was to 1) describe the neuromechanical profiles throughout the landing phase of single-leg and double-leg forward landings in males and females, 2) quantify the contributions of gluteal muscle strength and activation to peak angles and moments of functional valgus collapse after controlling for one's femoral alignment, and 3) explore the association between gluteal muscle function and overall functional valgus collapse throughout the landing phase. To accomplish this, 45 females and 45 males with no history of knee surgery were measured for femoral anteversion, hip ROM, and hip strength and then underwent biomechanical testing during single-leg and double-leg forward landings to examine muscle activation and 3-dimensional biomechanics. Data were analyzed using conventional group and correlative analyses and also with statistical parametric mapping (SPM), which allowed for a more comprehensive examination of the entire biomechanical time series. Biomechanical variables of interest included joint angles and moments comprising functional valgus collapse: hip adduction and internal rotation and knee abduction and internal rotation. In the comparison between single-leg and double-leg landings by sex, sex differences in the frontal plane were task dependent, though females maintained greater absolute knee abduction and hip adduction throughout the landing phases. Sex by task interactions revealed that females landed with smaller knee adduction angles than males, particularly during the single-leg landing (p=.03), while females' knee abduction excursion was greater than males', particularly during the double-leg landing (p=.01). Across task, females displayed 4.1° greater peak knee abduction than males (p=.002), and this was specific to 37-46% of the landing phase (p=.05). Females went through 1.0° more hip abduction than males (p=.05), and used a smaller proportion of their gluteus maximus (p=.01) in both tasks. Examination of gluteal muscle contribution to individual and overall levels of functional valgus collapse in females revealed that at the 18% and 20% time points during the landing phase, less hip abduction strength and greater gluteus medius activation predicted greater peak hip adduction angles (R2 change = .10; p = .02) and higher external hip adduction moments (R2 change = .14, p = .06). Greater hip extension strength predicted greater peak hip abduction angles (R2 change = .08; p = .05), while greater gluteus maximus activation strengthened the prediction of greater initial (R2 change = .10, p = .03) and peak (R2 change = .14, p = .01) knee internal rotation angles. From 7% - 8% of the landing phase, greater external rotation ROM was associated with greater external hip adduction moment (R2 change = .18, p = .01). In males, less hip abduction strength strengthened the prediction of greater initial (R2 change = .12, p = .01) and peak knee internal rotation angles (R2 change = .14, p = .01), lesser peak knee external rotation angles (R2 change = .07, p =.09), and lesser peak knee abduction moments (R2 change = .06, p =.11). Less hip extension strength with greater gluteus maximus activation predicted greater peak hip external rotation moments (R2 change = .14, p = .01). Specifically from the 3% - 9% time points of the landing phase, greater hip extension strength was associated with greater knee abduction moment (R2 change = .17, p = .01) and less hip adduction moment (R2 change = .24, p = .001). At 0% and from 2% - 3% of the landing phase, greater internal and external rotation ROM were associated with greater knee abduction angle (R2 change = .27, p = .01) and greater hip adduction angle (R2 change = .23, p = .02). These results indicate that lower extremity biomechanics during a single-leg landing task are appreciably different than those observed during a double-leg landing task, and that a single-leg landing task elicits more profound sex differences, particularly during the early stage of single-leg load acceptance when ACL injuries are thought to occur (30-40ms post initial ground contact). As such, a single-leg landing task may be more appropriate for biomechanical screening of ACL injury risk. Gluteal strength and activation explained a unique proportion of variance in lower extremity biomechanics beyond what was explained by femoral alignment. In females, weaker gluteal muscles predicted riskier frontal plane hip kinematics. In males, gluteal function was more associated with kinetics. This implies that our male cohort used their musculature to create torque about a joint, whereas our female cohort was unable to create torque. Though femoral alignment (total ROM) explained considerably greater proportions of biomechanical variance than did gluteal function, observed associations between gluteal muscle function and biomechanics occurred 10-20ms after associations between femoral alignment and biomechanics. While the gluteal muscles may act mechanically independent of femoral alignment, it is possible that gluteal muscle function could be temporally linked to one's femoral alignment. With these findings in mind, it may be beneficial for clinicians to implement gluteal strengthening programs and to encourage gluteal muscle pre-activation in individuals with excessive hip ROM to lessen their propensity for functional valgus collapse."--Abstract from author supplied metadata.
