“…Decreased movement due to an external compression force is generally reported, and this is consistent with our hypothesis 7) . Although the present results show that the changes in pelvic motion were quite small, these changes were similar to previously reported results of 3.1° in the sagittal plane, 10.5° in the frontal plane, and 10.4° in the coronal plane, which were the values of the normal condition 5) . Our opinion is that the increased pelvic movement observed in the present study could be interpreted as representing compensation for reduced hip movement.…”

“…If gait is disturbed by an external compressive force or restraint factor, the repetitive movement pattern of the gait might demonstrate a reduced range of motion. Smith et al 5) reported that wearing a backpack could be a restrainting factor with respect to trunk movement during gait 5) . We hypothesized that wearing tight pants would decrease the range of motion during gait.…”

Abstract.[Purpose] The purpose of this study was to evaluate the effect of the tight pants on kinematic data of the hip and pelvis during women's gait. [Subjects] We recruited 15 asymptomatic women.[Methods] Walking was performed under two different conditions: gait with and without wearing tight pants. Kinematic data of right hip and pelvis were recorded using a 3D motion-capture system.[Results] The changes of the anterior, external pelvic rotation significantly increased under the tight pants condition, while the changes of hip flexion, abduction, and external rotation significantly decreased under the tight pants condition.[Conclusion] Frequent wearing of tight pants has the possibility of inducing excessive pelvic rotational movement in women.

“…Despite the use of redundant markers to track the pelvis, considerable marker dropout resulted in a lack of accurate and consistent pelvis data. Such data could provide additional information for assessing injury risk, particularly related to the lower back [20][21]. Also, participants in the current study wore athletic sneakers as opposed to combat boots that would be commonly worn in theater.…”

Abstract-The biomechanical responses to load carriage, a common task for dismounted troops, have been well studied in nondisabled individuals. However, with recent shifts in the rehabilitation and retention process of injured servicemembers, there remains a substantial need for understanding these responses in persons with lower-limb amputations. Temporalspatial and kinematic gait parameters were analyzed among 10 male servicemembers with unilateral transtibial amputation (TTA) and 10 uninjured male controls. Participants completed six treadmill walking trials in all combinations of two speeds (1.34 and 1.52 m/s) and three loads (none, 21.8, and 32.7 kg). Persons with TTA exhibited biomechanical compensations to carried loads that are comparable to those observed in uninjured individuals. However, several distinct gait changes appear to be unique to those with TTA, notably, increased dorsiflexion (deformation) of the prosthetic foot/ankle, less stance knee flexion on the prosthetic limb, and altered trunk forward lean/excursion. Such evidence supports the need for future work to assess the risk for overuse injuries with carried loads in this population in addition to guiding the development of adaptive prosthetic feet/components to meet the needs of redeployed servicemembers or veterans/civilians in physically demanding occupations.

“…Relatively few studies involving posterior load carriage in gait have reported pelvic and hip angles (Smith et al, 2006). This may be due to the difficulty in positioning markers on pelvic bony prominences during these tasks.…”

Valid measurement of pelvic and hip angles during posterior load carriage gait task requires placement of pelvic markers which will not be occluded or physically displaced by the load. One solution is the use of pure lateral pelvic clusters to track the pelvis segment. However, the validity of this method has not been compared against pelvic marker systems recommended by the International Society of Biomechanics (ISB) during high impact tasks, such as running. The purpose of this study was to validate the lateral tracking pelvic clusters against the ISB pelvis during running. Six participants performed overground running at a self-selected running speed with shoes. Three dimensional motion capture and synchronised in-ground force plates were used to determine lower limb joint angles and gait events respectively. Two biomechanical models were used to derive pelvic segment and hip joint angles. The ISB pelvis used the anterior and posterior iliac spines as anatomical and tracking markers, whilst the other model used lateral pelvic clusters as tracking markers. The between participant averaged coefficient of multiple correlation suggested good to excellent agreement between the angle waveforms generated from the two marker protocols. In addition, both marker protocols had similar sensitivity in detecting three dimensional pelvic and hip joint angles during the stance phase. This study suggests that in the event posterior load carriage is involved in running gait, pelvic and hip kinematics can be measured by the use of lateral pelvic clusters.
