“…Huffman et al showed an increase in obese hip adduction moment normalized to a subject height and weight. 28 Although our study did not normalize the hip adductor moments, a similar result was seen. Normally, obese participants have a greater ground reaction force compared with TD participants, especially at slow walking speeds.…”

“…14 McMillan et al and Huffman et al had higher values of hip adduction than the current study (16.4°and 14.3°, respectively), but also followed the trend of increased hip adduction in obese participants. 19,28 Finally, Shultz et al showed obese subjects had increased hip adduction, but their results were not statistically significant. 18 Overall, hip adduction findings are consistent across studies, supporting the validity of our gait results.…”

Childhood obesity in the United States has more than tripled in the past three decades. Differences in lower extremity kinematics between obese and nonobese children during walking have been investigated, but the validity of using the gait deviation index (GDI) for measuring gait in obese children has not been explored. Nine obese children (13.9 ± 2.4 years old) with a body mass index of 33.3 ± 3.5 participated in the study. Reflective markers were placed on all children in a widely used standard lower extremity marker configuration. All participants walked along a 20-foot walkway at a self-selected speed. The kinematic and kinetic measurements for all children were taken, and the GDI for each subject was calculated. The mean ± standard deviation (SD) GDI of the nine obese children was 88.5 ± 12, which was significantly lower than the GDI of the typically developing children (100 ± 10, p < 0.002). There were no statistically significant correlations between the GDI and the Pediatric Quality of Life (PedsQL) Total score or PedsQL Physical Functioning score. Obese children had a significantly increased anterior pelvic tilt, hip flexion, hip adduction, hip adduction moment, knee flexion, knee valgus, and plantar flexion in stance phase (p < 0.05). While in swing phase, obese children had increased hip adduction and knee varus. The kinematic differences may reveal lower limb mal-alignment in obese children during walking. Overall, the GDI can play a major role in evaluating gait pathology in obese children. Future studies will increase the sample size to further evaluate the correlation between the GDI and functional outcomes.

“…The findings of the present study should be taken with caution because the STS task has many variable factors that may influence the results, such as the chair seat height, the use of armrests [ 32 ] and variations in age [ 49 ] and BMI [ 50 ] of the subjects.…”

Muscular Activity and Fatigue in Lower-Limb and Trunk Muscles during Different Sit-To-Stand Tests

Sit-to-stand (STS) tests measure the ability to get up from a chair, reproducing an important component of daily living activity. As this functional task is essential for human independence, STS performance has been studied in the past decades using several methods, including electromyography. The aim of this study was to measure muscular activity and fatigue during different repetitions and speeds of STS tasks using surface electromyography in lower-limb and trunk muscles. This cross-sectional study recruited 30 healthy young adults. Average muscle activation, percentage of maximum voluntary contraction, muscle involvement in motion and fatigue were measured using surface electrodes placed on the medial gastrocnemius (MG), biceps femoris (BF), vastus medialis of the quadriceps (QM), the abdominal rectus (AR), erector spinae (ES), rectus femoris (RF), soleus (SO) and the tibialis anterior (TA). Five-repetition STS, 10-repetition STS and 30-second STS variants were performed. MG, BF, QM, ES and RF muscles showed differences in muscle activation, while QM, AR and ES muscles showed significant differences in MVC percentage. Also, significant differences in fatigue were found in QM muscle between different STS tests. There was no statistically significant fatigue in the BF, MG and SO muscles of the leg although there appeared to be a trend of increasing fatigue. These results could be useful in describing the functional movements of the STS test used in rehabilitation programs, notwithstanding that they were measured in healthy young subjects.

“…This model regarded the cervical spine as one rigid segment and the lumbar spine as another rigid segment, where C7-T1 junction was defined as CT joint and L5-S1 as LS joint. AP reaction force was normalized by body mass considering that reaction force has a proportional relationship with body mass [ 29 , 30 ]. Joint moment was also normalized by body mass times height (Nm/(kg*m)) [ 23 , 29 , 31 ].…”

BACKGROUND: The sitting in an awkward posture for a prolonged time may lead to spinal or musculoskeletal disease. It is important to investigate the joint loads at spine while sitting.OBJECTIVE: The purpose of this study was to investigate the joint moment and antero-posterior (AP) reaction force at cervico-thoracic and lumbosacral joint for various sitting postures.METHODS: Twenty healthy males participated in this study. Six sitting postures were defined from three spinal curvatures (slump, flat, and lordosis) and two arm postures (arms-on-chest and arms-forward). Kinematic and kinetic data were measured in six sitting postures from which joint moment and AP reaction force were calculated by inverse dynamics.RESULTS: In the cervico-thoracic joint, joint moment and AP reaction force were greater in slump than the flat and lordosis postures (p< 0.001) and also in arms-forward posture compared to arms-on-chest posture. In the lumbosacral joint, joint moment and AP reaction force were greater in slump than flat and lordotic posture (p< 0.001) but there was no difference between different arm postures. The joint loads (moment and AP reaction force) at the cervico-thoriacic joint were closely related to the head flexion angle (r> 0.86) while those at the lumbosacral joint were correlated to the trunk flexion angle (r> 0.77). In slump posture, the joint moments were close to or over the extreme of the daily life such as sit-to-stand and walking. Consequently, if the slump is continued for a long time, it may cause pain and diseases at the cervico-thoracic and lumbosacral joints.CONCLUSIONS:The results of the study indicated that the lordosis or flat would be better spinal postures. Also, keeping arms close to body would be desirable to reduce joint loads.
