Squat Muscle Activation Patterns with Hip Rotations in Subjects with Genu Varum Deformity

et al. 2020

The purpose of this study was to compare muscle activation during the squat with different hip rotations (neutral, 15, 30, and 45° of internal and external hip rotation) in subjects with and without Genu Varum deformity deformity. Surface electromyography were recorded from 32 men with (n=16) and without (n=16) Genu Varum deformity. In the Genu Varum deformity group, the squats with 30, 45 and 15° of internal rotations of the hip showed significantly greater gluteus medius activation as compared to other positions. Moreover, the tensor fascia lata activity increased with greater external rotation of the hip, and significantly more than hip internal rotations (p<0.05). For vastus medialis and vastus lateralis, both hip internal and external rotation showed a significantly greater activation compared to the neutral hip positions (p<0.05). There were significant differences in the gluteus medius:tensor fascia lata activity ratio (p=0.001) and the vastus medialis: vastus lateralis activity ratio (p=0.001) between the different hip positions in the Genu Varum deformity and healthy groups. These results demonstrate that muscle activation patterns varied significantly with the position of different hip rotation in both groups. Those with Genu Varum deformity may use this information to aid in an injury prevention strategy by choosing squat positioning that favorably alters muscle activation patterns.

The aim of this study was to evaluate the effects of a pop dance exergaming protocol on fall risk factors-depressive symptoms, fear of falling, and musculoskeletal function-in community-dwelling older female fallers and nonfallers. There were 47 community-dwelling older women assigned to the intervention group (IG) [fallers (n = 10, 69.8 ± 4.3 years); nonfallers (n = 12, 68.9 ± 3.3 years)] and the control group (CG) [fallers (n = 12, 73.6 ± 5.4 years); nonfallers (n = 13, 68.7 ± 4.8 years)]. The CG maintained their lifestyle and the IG performed a videogame dance training three times per week for 12 weeks. The Dance Central game for Xbox 360 and Kinect motion sensor were used. The primary outcomes were geriatric depressive symptoms, fear of falling, and concentric and eccentric isokinetic peak torque (PT) of quadriceps and hamstrings. Secondary outcomes included cross-sectional area of quadriceps and hamstring muscles, functionality (Timed Up and Go test, gait speed, the Five Times Sit-to-Stand test), and a fall circumstances and outcomes recording. The depressive symptoms decreased in the Intervention Fallers Group. The eccentric hamstrings PT at 180°/s increased in the Intervention Nonfallers Group. There were no significant differences between groups for the other variables analyzed. The training attendance was 83% for the Intervention Fallers Group and 88% for the Intervention Nonfallers Group. Dance exergaming can be indicated to decrease depressive symptoms in fallers and increase the PT in nonfallers among community-dwelling older women.
