Background: Observation and research on pure and natural movements and movements born of human nature have been carried out for many years. However, biomechanics study is still very less for the complex movements from lying on a floor to standing position. In particular, there is still little scientific and scientific research on the movements observed during the unconscious developmental process until babies acquire standing and walking. In this study, two patterns: Spiral and Parallel which relates baby motion development were focused. We examined the characteristics of the changes in the motion trajectory and the body pressure dispersion from the biomechanical point of view in the motion from the floor to standing. Developmental studies of human fundamental movements may be associated with appropriate signals to cells, tissues, and organs, as well as with health maintenance and development and care applications for the sick, disabled, and also the healthy people. This study will provide basic data.Methods: Healthy volunteers who finished training about baby development movement course were recruited by a snowball sampling. Two fundamental Spiral and Parallel movements from a supine position to a standing position on the floor, which are said to reproduce a general developmental process naturally acquired in the growth process of a baby, were analyzed for 5 times each. The three procedure was analyzed with a 42 segments model using a 3D motion analysis VICON. The analysis of observation for the movement process, the force plate, and the movement lotus were examined.Results: One female volunteer aged 30's who finished the training was analyzed in Spiral and Parallel movements for 5 times each. The Spiral movement was distributed to various parts of the body, and repeated circular movements irregularly in a wider space. The Spiral movement was observed a circular trajectory like a figure eight motion as a whole. The Parallel movement was a straight line on the sagittal plane, shifting the body weight back and forth, repeated flexion and extension movements, and moved upward. The motion locus of the linear waveform was repeatedly operated, and it was indicated that it moved back and forth on the sagittal plane in the Parallel movement.Conclusion: The Spiral movement was distributed to various parts of the body, and repeated circular movements in a wider space of sagittal plane, frontal plane and horizontal plane, and moved upward. Spiral movement was a circular trajectory like a figure eight motion irregularly distorted in wider three dimensions. The Parallel movement was a straight line on the sagittal plane, shifting the body weight back and forth, repeated flexion and extension movements, and moved upward. Parallel movement was the operating locus having a linear waveform back and forth on the sagittal plane.

AbstractBackground: The purpose of this study was to compare body balance in road and off-road cyclists, immediately before and after the racing season.Material/Methods: Twenty individuals participated in the study and they were divided into two groups: specialists in road-cycling (n = 10) and in off-road cycling (n = 10). Immediately before and after the five-month racing season stabilographic trials were carried out (at rest and after progressive exercise). In assessing body balance the distance and velocity of the centre shifts (in the anterior-posterior and left-right direction) were analysed. The tests were performed with the cyclists’ eyes open, eyes closed, and in feedback.Results: After the racing season, in the off-road cyclists’ group, distance and velocity of the centre of pressure shifts increased after a progressive exercise.Conclusions: In the off-road cyclists’ group the balance of the body in the sagittal plane deteriorated after the racing season. Moreover, after the racing season off-road cyclists were characterized by a worse balance of the body, compared to road cyclists

The aim of this study was to evaluate the intra- and inter-examiner reliability and validity of neck range of motion (ROM) measurements. Thirty-five healthy subjects were assessed in all neck movements from two initial positions, sitting and standing, actively (open and closed eyes) and passively by using a 3D ultrasound-based motion analysis device (Zebris). Three tests were employed to assess intra-examiner reliability and two examiners used for the inter-examiner reliability. X-rays in neck flexion and extension were used to validate the Zebris system. The standing position yielded higher intraclass correlation coefficient (ICC) values (>0.86) with less error [smallest detectable difference (SDD) < 13.8%] than sitting (ICC > 0.79, SDD < 14%). Passive assessment of neck ROM presented better reproducibility than active assessment with open or closed eyes in both positions. The inter-examiner reliability was moderate (ICC = 0.43-0.68). The correlation between the Zebris system and X-rays was high in both flexion and extension movements. The results showed that the most reliable protocol for assessment of neck ROM is a passive measurement in the standing position. The measurements were well validiated against X-rays and the experience of the investigators must be considered before any comparison among studies is employed.

AbstractIn the present study, precise, animal-based biometric data on the space needed for the body dimensions of individual pigs (static space) were collected. Per batch, two groups of eight piglets each were formed after weaning (35 days old). Using three-dimensional cameras that recorded a piglets’ pen from above and newly developed software, the static space of individuals was determined over 6 weeks. The area covered by an individual increased almost linearly with increasing body weight (R2 = 0.97). At the end of rearing (25 kg body weight), an individual covered 1704 cm2 in standing position, 1687 cm2 in sitting posture and 1798 cm2 in a recumbent position. According to the allometric equation: Space = k × body weight0.667, k values for the static space in standing position (k = 0.021), in recumbent position in general (k = 0.022) and in lateral recumbent posture (k = 0.027) were calculated. Compared with spatial requirements in different countries, the results of static space obtained in the present study revealed that pigs weighing 25 kg are provided with 0.09–0.18 m2 free space per pig which is not covered by the pig's body. This free space can be used as dynamic space needed for body movements or social interactions. The present study was not intended to enhance space recommendations in pig farming, but to demonstrate the amount of free space in a pigs’ pen. It was shown that innovative technologies based on image analysis offer completely new possibilities to assess spatial requirements for pigs.

Objectives Adrenal gland size and its association with body weight have been rarely evaluated in cats. This study was undertaken to assess the association between feline body weight and adrenal gland thickness, and to propose reference intervals (RIs) for adrenal gland thickness in healthy cats. Methods This was a cross-sectional study in which 39 healthy cats were included. The cats were divided into two weight categories, classified as ⩽4.0 kg and >4–8 kg of ideal body weight (with 13 and 26 cats in each group, respectively), which took into consideration the body condition score of the cats. All cats underwent an ultrasound examination that was taken from a subcostal position. Maximum dorsoventral thicknesses of the left (MTL) and right (MTR) adrenal glands were measured in a sagittal plane. RIs were obtained for the maximum thickness (MT), which included the MTLs and MTRs of each cat. RIs with the 90% confidence intervals were calculated according to American Society for Veterinary Clinical Pathology guidelines on RIs. Results No statistical differences for adrenal gland thickness were observed between the left and right ( P = 0.543) adrenal glands or between male and female cats ( P = 0.943). Mean MT was significantly greater in the group of cats weighing >4–8 kg compared with the group of cats weighing ⩽4 kg (3.7 ± 0.6 vs 3.2 ± 0.4 mm; P <0.005). The lower limit of the RI for MT was 2.4 mm (range 2.2–2.6 mm) in the group weighing ⩽4 kg and 2.6 mm (range 2.4–2.8 mm) in the group weighing >4–8 kg. The upper limit of the RI for MT was 3.9 mm (range 3.7–4.1 mm) in the group of cats weighing ⩽4 kg and 4.8 mm (range 4.6–5.1 mm) in the group of cats weighing >4–8 kg. Conclusions and relevance The use of RIs based on two group sizes allows for a more accurate ultrasonographic evaluation of adrenal gland thickness in cats. The maximum normal adrenal gland thickness is lower in smaller cats (3.9 mm for those weighing ⩽4 kg and 4.8 mm for those weighing >4–8 kg).

Abstract Background Postural assessment is an important part of the physical examination in the physical therapy practice. One of the most commonly used clinical tests is an arm-raising Matthiass test. The aim of this study was to investigate posture changes in sagittal plane observed during Matthiass test in young adults using a rasterstereography method. Methods Fourteen young and healthy volunteers, nine female and four male aged between 21 and 25 took part in this study. Examination s performed with the rasterstereographic measuring device. Results Trunk inclination significantly decreased during Matthiass test and the pelvis inclination increased. Distance between kyphosis apex and cervical lordosis apex was significantly shorter during the test than in standing position. Distance between kyphosis apex and lumbar lordosis apex significantly increased during Matthiass test. Kyphosis angle was significantly decreased and the lumbar lordosis angle was increased during the test. Conclusion The results of this study suggest that Matthias test can cause significant deviations in posture in young participants. Changes in the sagittal plane are observed mainly right after the elevation of the arms.

Introduction: Concern about weight gain among people has been high due to negative health consequences in addition to the increasing prevalence of the problem. Overweight and obesity also occur in patients with hemophilia. Analysis of literature shows that increased body weight might have a biomechanical effect on the spatial orientation of the pelvis and the lumbar spine. The aim of this study was to determine the correlation between body mass index (BMI) and the parameters characterizing the alignment of the sacrum (SS, sacral slope), the pelvis (PT, pelvic tilt; PI, pelvic incidence) and the angle value of lumbar lordosis (LL, lumbar lordosis) assessed in the sagittal plane among patients with hemophilia. Materials and methods: A total of 49 patients were subjected to the study, 23 of whom met the inclusion criteria. Body weight and height were measured. Measurement of the angle values of indicators characterizing the position of the lumbar–pelvic complex was established based on X-ray imaging analysis. Results: Analysis of the correlation between the BMI and sacral, pelvic, and lumbar indicators evaluated in the sagittal plane in the study group of patients with hemophilia showed a correlation between BMI and SS (r = 0.48). SS values were significantly and positively related to PI (r = 0.6; p = 0.002) and LL (r = 0.46; p = 0.02). The results obtained indicate the BMI relationship with the setting of the sacrum in the sagittal plane (SS). After adjusting for the knee flexion contracture, the correlation on the border of significance (b = 0.73, p = 0.07) between the body mass index and the spatial orientation of the pelvis and the spine was revealed. Conclusion: We hypothesize that increased body weight among people with hemophilia might have an effect on the positioning of the lumbosacral region. Therefore, it is believed that preventing obesity among people with hemophilia can contribute to a smaller number of intra-articular hemorrhages and better orthopedic condition of the limb joints, and thus could avoid changes in the lumbosacral region as well as their consequences.

The aim of this study has been to determine the relationship between the shape of the thoracic kyphosis, lumbar lordosis and sagittal trunk inclination, and the longitudinal and transverse arches of the feet, the position of the hallux and the fifth toe in women with normal and excessive body weight. Material and methods: Eighty nine women aged from 57 to 84 were studied. The shape of the spine was examined using the Zebris pointer ultrasound system, and the shape of feet was evaluated with a podoscope with a 3D scanner. The data analysis was performed using the Statistica v13 software, frequency tables, descriptive statistics, the Kruskal-Wallis test, the post hoc Tukey test, and Spearman’s rank-order correlations coefficient. Obesity has been reported to increase thoracic kyphosis, increase the forward lean of the trunk and flatten the longitudinal arch of the feet. It was found that there is a relationship between the forward lean of the body and the reduction in the longitudinal and transverse arch of the feet and the valgus position of the hallux, and between the degree of thoracic kyphosis and the valgus position of the hallux. Excess body weight, to a greater extent than age, influences the position of the trunk and the shape of feet in older women. A feature of the body posture that is characteristic of older women is the progression of thoracic kyphosis and lumbar lordosis, the forward lean of the body and the lowering of the arch of the feet.

In this experiment eighteen (18) apparently healthy female cats were assigned in three anesthetic groups to attain the objectives of assess the efficacy and adverse effects of anesthetic agents. The body weight of the cats ranged from 2.5 to 3 kg and 8 to 12 months of age. There were divided into following three groups; A: atropine sulphate (0.04 mg/kg), xylazine hydrochloride (1 mg/kg) and Ketamine hydrochloride (5 mg/kg) body weight intramuscularly, B: xylazine hydrochloride (1 mg/kg) and ketamine hydrochloride (5 mg/kg) body weight intramuscularly and C: ketamine hydrochloride (5 mg/kg) and diazepam (1.4 mg/kg) body weight intramuscularly. The mean of induction period was significantly (P<0.05) shorter in Group A and B. Duration of anesthesia, time to first movement there was no difference among these three groups. The induction period was 2.67±0.82, 3.17±0.75 and 13±2.28, Duration of anesthesia was 34.17±2.40, 39.33±1.75 and 35.33±2.73, Time to first movement was 7.5±1.52, 6.67±1.03 and 7±0.894, Time to sternal position was 10.67±1.21, 10.33±1.03 and 19.83±2.07, Time to standing position was 14.67±2.07, 14.33±1.51 and 26.22±2.61 respectively in case of Group A, Group B and C. The induction, duration and recovery period from anesthesia was smooth in atropine sulphate-xylazine-ketamine hydrochloride combination. Salivation was found in xylazine-ketamine hydrochloride combination. Vomition observed onset of action and salivation during recovery period in Ketamine hydrochloride-Diazepam combination. From this study it was found that atropine sulphate-xylazine-ketamine hydrochloride does not show any adverse effect on cat and is an identical satisfactory anesthetic combination which will be helpful for performing any surgical interventions for cats.

Blindfolded or disoriented people have the tendency to walk in circles rather than on a straight line even if they wanted to. Here, we use a minimalistic walking model to examine this phenomenon. The bipedal spring-loaded inverted pendulum exhibits asymptotically stable gaits with centre of mass (CoM) dynamics and ground reaction forces similar to human walking in the sagittal plane. We extend this model into three dimensions, and show that stable walking patterns persist if the leg is aligned with respect to the body (here: CoM velocity) instead of a world reference frame. Further, we demonstrate that asymmetric leg configurations, which are common in humans, will typically lead to walking in circles. The diameter of these circles depends strongly on parameter configuration, but is in line with empirical data from human walkers. Simulation results suggest that walking radius and especially direction of rotation are highly dependent on leg configuration and walking velocity, which explains inconsistent veering behaviour in repeated trials in human data. Finally, we discuss the relation between findings in the model and implications for human walking.

The aim of this study was to estimate different body measurements and derive prediction equation for live weight of Jamuna basin sheep using different body measurement. A total of 520 individual records of sheep (47 males and 473 females) including all temporary at nine-month age (320), first pair permanent at 1.6 year age (161) and 2nd pair permanent at two years age (39) were collected from two Upazila of Sherpur district. Body weight (BW) was taken using a weighing scale and different measurements were taken using the tailor's tape measure and measuring stick while animals were on standing position. Data were analyzed with the help of SPSS-v-20 computer package program. Average BW, wither height(WH), rump height(RH), body length(BL), sternum height(SH), body depth(RD), bi-costal diameter(BD), ear length(EL), rump width(RW), head width(HW), rump length(RL), head length(HL), heart girth(HG), cannon bone circumference(CC) and muzzle diameter(MD) were 12.28±2.75 kg, 49.42±3.78, 54.04±3.88, 49.38±4.57, 28.06±3.00, 53.09±4.40, 15.07±2.58, 8.66±3.32, 15.72±2.33, 12.87±2.20, 14.30±2.29, 18.23±2.30, 55.02±4.71, 9.22±1.01, and 16.65±1.73cm, respectively. According to sex BW, WH, RH, SH, RD and CC were found significant (p<0.001), HG and MD were found significant(p<0.01). Stepwise multiple regression analysis according to agein all temporary groups showed that the body weight was found the best fitted equation having the highest R2value 64% (BW = - 15.53+0.24HG+0.13WH+0.16BD-.1RW+0.05EL) whereas in 1.3-1.6 and 1.9-2 years age group the R2 value for BD was 56 (BW = - 15.65+0.31HG+0.22WH)and 83% (BW = -24.51+0.21RH+0.35HG+0. 19BL-0.78RL+1.2RW-0.87HW), respectively. R2value for BD in male (BW = -28.91+0.43HG+0.35WH) and female (BW = -10.62+0.27HG+ 0.13WH+0.06BD-0.13HW+0.07BL-0.10SH-0.10RL) was 88and 59%, respectively. It is concluded that the best prediction parameter of BW was HG, WH, BD, RW, EL, RH, BL and HW. SAARC J. Agri., 18(1): 183-196 (2020)
