Do men and women use similar adaptive locomotion to clear static and dynamic obstacles?

Purpose. The purpose of this study was to analyze the influence of gender on the adaptive locomotion in the clearance of obstacles. Specifically, it was evaluated if there are differences in the space-temporal parameters between male and female in the clearance of and dynamic obstacles moving at both slow and fast speeds. Basic procedures. Five young male adults and five young female adults took part in this study. The task was performed in three conditions: static obstacle and dynamic obstacle - clearance perpendicular to the participant's trajectory at slow speed (1.07 m/s) and at fast speed (1.71 m/s). The trials were recorded by two digital cameras and spatial-temporal information was obtained. Main findings. The dynamic obstacle conditions required more visual inspection. The results showed different adaptive locomotion between the sexes. The distinct gait patterns were evidenced for the spatial and temporal variables and cadence in the three conditions. Conclusions. The women presented a more conservative behavior, which was evidenced by the increase of the length in the penultimate step and in the toe clearance.

Craniometria em cães (Canis familiaris). Aspectos em crânios mesaticéfalos

In this study, a total of 25 skulls of the adult, mongrel and mesaticephalics dogs were used. Craniometric measurements for different parts of the skull were made. Cephalic indices and ratios were calculated. Certain points and landmarks on the skull are recognized in making linear measurements and are inion, bregma, nasion, prosthion, pogonion, basion, euryon, and zygion. Skull height (41,92 mm ± 3,9), skull length (177,72 mm ± 16,22), neurocranium (96,84 mm ± 7,25), viscerocranial (79,24 mm ± 8,72), basal length (140,24 mm ± 12,21), condylobasal (149,32 mm ± 12,21), snout (69,84 mm ± 7,07), nasals (50,08 mm ± 6,77), mandibular (129,88 mm ± 16,3), and of palatal (76,84 mm ± 7,01); width of neurocranium (62,24 mm ± 3,8), and zygomatic (95,44 mm ± 7,85) were obtained. Therefore, were calculated cranial index (53,83 mm ± 3,36), neurocranium (64,48 mm ± 4,69), facial (121,06 mm ± 9,18), basal (44,64 mm ± 4,17), width of the jugular processes (41 mm ± 4,2), of occipital condyles (35,48 mm ± 3,21), and of the foramen magnum (17,48 mm ± 2,27); height of the occipital triangle (38,28 mm ± 3,35), of the foramen magnum (14,36 mm ± 1,07); length of the dorsal notch (16,1 mm ± 1,12), and foramen magnum index (83,71 mm ± 14,44). Although with some differences in measurements, no significant difference was observed between the dimensions and reported to mesaticephalic skulls.

Lower limb strength is associated with gait biomechanical abnormalities in older female fallers and non-fallers

BACKGROUND: Age-related loss in lower limb strength is related with impaired mobility. However, the association between decreased lower limb strength and gait biomechanical abnormalities is unclear. %In line with this, With respect to these statements, our study aimed to compare the maximum isokinetic voluntary strength (MIVS) of hip, knee and ankle of older women with and without history of falls. Also, we correlate the strength of each group with gait biomechanics. METHODS: The MIVS were assessed during concentric/concentric movements performed for hip, knee and ankle joints. Gait biomechanics (kinematic and electromyography) were assessed during 1-minute recorded during the volunteers walking on the treadmill at self-selected speed. Electromyographic signal was analyzed by the linear envelop after heel strike and before toe-off. The kinematic data were analyzed using the variables: step time, length and step width and ankle angle at heel strike, and hip angle at toe-off. RESULTS: In faller group, we found that a decreased hip abduction and adduction MIVS is associated with a higher tibialis anterior activation at initial stance (p =0.04 and r =-0.53 and p=0.04 and r=-0.52). CONCLUSION: Therefore, an impaired strength of hip could causes compensation in ankle stabilizer muscles activation at initial stance in older female fallers. © 2013 - IOS Press and the authors.
