BetaSPC is a technology that uses a microcontroller (Arduino Duemillanove) as processors and sensors (infrared) which is based on the amount of light reflected on a clothes stretched (when the bent body position). With the technology used in BetaSPC allows one to determine the proper posture when sitting at a computer or laptop and improve posture during sitting. When someone is in front of the laptop or computer by sitting in an upright posture, the posture shoulder (shoulder) on the back will change clothes behind, just below the shoulder blade position becomes meragang. If someone sitting at a computer or laptop to a sitting position in a bent posture then clothes (clothes) behind, just below the shoulder blade will be stretched (tight). Then, stretch clothes that will activate the buzzer (sound and vibrate) to provide feedback to the user about the current posture stretch shirt (hunchback) so as to commemorate and improve the position of his body correctly (perpendicular) when using a computer or laptop.

Abstract: Low Back Pain (LBP) is the most frequent musculosceletal issue found in daily work. Extenuating physical positions comprise 80-85% of the caues of  LBP. In the medical world, a lot of causes of LBP do not identify the pathoanatomical disorders. These factors are e.g.: body in static position while working and the working body position leaning heavily on the vertebra (for example: sitting in a hunched position, sitting upright without back support, or working for unsually long periods of time). Until now in Manado no study has been carried out to show the correlation between LBP and the sitting position, or the duration of work. This study aimed to find out the correlation between chronic LBP and the sitting position or the duration of work among bank employees in one of the goverment banks in Manado. The results showed that there were 69 respondents involved in this study. Chronic LBP was found in 62 respondents (90%). Up stright position while sitting was the most frequent position that caused chronic LBP in 28 respondents. The average time used for working with sitting position was 7-8 hours which caused chronic LBP among 31 respondents of the group with the work time from 11.00-13.59. A P-value of 0.000 (<0.05) showed that there was a strong correlation between sitting position and chronic LBP. Duration of work also showed a strong correlation with chronic LBP with a P-value of 0.000. Conclusion: There were strong correlations beween chronic low back pain with sitting position while working and duration of work. Keywords: chronic LBP chronic, sitting position, duration of work, bank employees.   Abstrak:Nyeri Punggung Bawah (NPB) merupakan gangguan muskuloskeletal yang paling sering dijumpai dalam aktivitas kerja. Faktor mekanik mencakup 80-85% dari keseluruhan penyebaNPB. Patoanatomi sering tidak dapat memberikan ketepatan diagnosis NPB oleh proses mekanik. Faktor mekanik yang mempercepat terjadinya gangguan NPB antara lain posisi badan yang cenderung statis, posisi badan yang cenderung memperberat kerja tulang-tulang vertebra seperti posisi badan membungkuk, tegak tanpa sandaran, dan waktu bekerja yang lama saat duduk. Hubungan NPB dengan posisi dan lama duduk belum pernah dilaporkan di Kota Manado. Penelitian ini bertujuan untuk mengetahui hubungan posisi dan lama duduk saat bekerja yang dapat menimbulkan NPB mekanik kronik pada karyawan bank. Hasil penelitian memperlihatkan dari keseluruhan responden yang berjumlah 69 orang, didapatkan 62 responden (90%) yang mengalami NPB mekanik kronik. Posisi duduk tegak tanpa sandaran merupakan posisi terbanyak menimbulkan NPB mekanik kronik pada 28 responden. Rata-rata lama duduk bekerja 7-8 jam menyebabkan NPB pada kelompok pukul 11.00-13.59 sebanyak 31 responden. Analisis statistik menggunakan uji chi-square memperlihatkan adanya korelasi yang kuat (P = 0,000) antara posisi duduk dan NBP mekanik kronik Lama duduk juga berkorelasi kuat dengan NBP mekanik kronik (P = 0,000). Simpulan: Terdapat hubungan yang kuat antara NBP mekanik kronik dengan posisi dan lama duduk pada karyawan bank. Kata kunci: NPB mekanik kronik, posisi duduk, lama duduk, karyawan bank.

PURPOSE Intralumbar methotrexate is one of the primary therapeutic modalities for the prevention and treatment of meningeal leukemia. However, methotrexate distribution to the ventricles is limited and highly variable following intralumbar dosing, and cytotoxic concentrations of methotrexate are not always achieved or sustained in the ventricular CSF. We used a nonhuman primate model to determine the effect of body position on the caudal distribution of an intralumbar dose of methotrexate. METHODS Methotrexate (1.0 mg) was administered by intralumbar injection to four animals, which were then immediately placed either in an upright sitting position or in a prone position for 1 hour, then upright. Each animal served as its own control and was studied in each position on at least one occasion. RESULTS The mean peak ventricular methotrexate concentration was 0.12 mumol/L (range, 0.091 to 0.20) in animals that were immediately placed upright, compared with 2.81 mumol/L (range, 0.21 to 8.9) in animals that remained prone for 1 hour. The mean area under the concentration-versus-time curves (AUC) was 0.51 mumol/L.h (range, 0.26 to 1.1) in the upright animals and 12.0 mumol/L.h (range, 0.9 to 35.4) in the prone animals. CONCLUSION Maintaining a prone position for 1 hour after an intralumbar dose increased the peak methotrexate concentration and drug exposure in ventricular CSF. CSF drug distribution following intralumbar therapy can be influenced by body position after the injection.

Background The esophagus has a different response in relation to the characteristics of a swallowed bolus. Bolus viscosity and body position may affect esophageal contraction and transit. Objectives To investigate the effect of bolus viscosity and body position on esophageal contraction, transit and perception. Methods Esophageal contraction, transit and perception of transit were evaluated in 26 asymptomatic volunteers, 13 men and 13 women aged 18-60 years, mean: 33.6 (12.2) years. Esophageal contraction (manometry) and transit (impedance) were measured with a solid state catheter with sensors located 5, 10, 15, and 20 cm from the lower esophageal sphincter. Each volunteer swallowed in duplicate and in random sequence a 5 mL low viscous (LV) liquid bolus of an isotonic drink with pH 3.3, and a 5 mL high viscous (HV) paste bolus, which was prepared with 7.5 g of instant food thickener diluted in 50 mL of water (pH: 6.4). Results Total bolus transit time, in the sitting position, was longer with the HV bolus than with the LV bolus. Esophageal transit was longer in the supine position than in the sitting position. Bolus head advance time was longer with the HV bolus than with the LV bolus in both positions. Contraction esophageal amplitude was higher in the supine position than in the sitting position. The perception of bolus transit was more frequent with the HV bolus than with the LV bolus, without differences related to position. Conclusions The viscosity of the swallowed bolus and body position during swallows has an influence on esophageal contractions, transit and perception of transit.

Introduction: Body position affects the respiratory mechanics and could be favorable to pulmonary function when combined with respiratory physiotherapy. Objective: Was to compare the ventilatory restriction in respiratory therapy techniques and changes of position. Method: For analysis of lung volume was measured Slow Vital Capacity (SVC) in university students in the positions: sitting, dorsal decubitus (DD), DD with application of maneuver thoracic blockade of the right hemithorax and right lateral decubitus (RLD). In all maneuvers were instructed to perform an inspiration to total lung capacity and slow exhalation to residual volume. Results: It was evaluated 26 subjects with a mean age of 25,5 ± 11 years and mean body mass index of 25 ± 4 kg/m2. The values obtained from SVC sitting, DD, DD with blockade and DLD were respectively 3,5 ± 1,5 liters (87,7 ± 26,8%); 2,9 ± 1,4 liters (75,0 ± 26,5%); 3,0 ± 1,4 liters (75,2 ± 26,2%); 3,5 ± 1,6 liters (88,3 ± 29,4%). Using the SVC in a sitting position as compared, there was no statistical difference in DD (p = 0,024) and DD with position blockade (p = 0,036). There was no significant difference in the DLD (p = 0,459) position. Conclusion: Can conclude that the positions DD and DD with blockade reduced lung volume, whereas DLD position showed no significant difference when compared to sitting position, suggesting that this position is an option favorable position for respiratory therapy.

History Of

A 26-year-old woman with a history of feeling nauseated during dental local anesthesia presented to our clinic for tooth extraction under intravenous sedation. Although she had experienced episodes of neurally-mediated syncope, her symptoms were controlled well with drug therapy, stopped 3 years earlier. No syncope episodes developed over the previous 2 years. Tooth extraction was performed under intravenous sedation without incident. When she was returned to a sitting position after being roused, convulsion, loss of consciousness, and cardiac arrest developed. One week later, similar symptoms occurred immediately after suture removal. We suspect that the change in body position triggered these episodes. It is important to avoid abrupt changes in body position and any other triggers and to administer preventive drugs in patients at high risk of syncope.

Normal Males

Variations in size of the various lung volumes due to changes in body position and as a consequence of treadmill exercise were studied in five normal males. Assumption of the upright posture was associated with highly significant increases in total lung capacity, vital capacity, expiratory reserve volume, and residual volume as compared to resting supine values. Level walking was associated with a decrease of expiratory reserve volume, but a further expansion of residual volume. Vital capacity decreased slightly, but total lung capacity increased by virtue of the proportionately large residual volume increases. Elevation of the treadmill to 4° resulted in slight decreases in all lung volumes, total lung capacity evidencing a barely significant decline. Positional changes in ventilation are described, and on the basis of the “lung clearance index” an increased efficiency of ventilation is seen in the upright posture. Factors possibly operative in these alterations are discussed. Submitted on February 21, 1962

Normal subjects have a larger diffusing capacity normalized per liter alveolar volume (DL/VA) in the supine than in the sitting position. Body position changes total lung diffusing capacity (DL), DL/VA, membrane conductance (Dm), and effective pulmonary capillary blood volume (Qc) as a function of alveolar volume (VA). These functions were studied in 37 healthy volunteers. DL/VA vs. VA yields a linear relationship in sitting as well as in supine position. Both have a negative slope but usually do not run parallel. In normal subjects up to 50 yr old DL/VA and DL increased significantly when subjects moved from a sitting to a supine posture at volumes between 50 and 100% of total lung capacity (TLC). In subjects greater than 50 yr old the responses of DL/VA and DL to change in body position were not significant at TLC. Functional residual capacity (FRC) decreases and DL/VA increases in all normal subjects when they change position from sitting to supine. When DL/VA increases more than predicted from the DL/VA vs. VA relationship in a sitting position, we may infer an increase in effective Qc in the supine position. In 56% of the volunteers, supine DL was smaller than sitting DL despite a higher DL/VA at FRC in the supine position because of the relatively larger decrease in FRC. When the positional response at TLC is studied, an estimation obtained accidentally at a volume lower than TLC may influence results. Above 80% of TLC, Dm decreased significantly from sitting to supine. Below this lung volume the decrease was not significant. The relationship between Qc and VA was best described by a second-order polynomial characterized by a maximum Qc at a VA greater than 60% of TLC. Qc was significantly higher in the supine position than in the sitting position, but the difference became smaller with increasing age. In observing the sitting and supine positions, we saw a decrease in maximum Qc normalized per square meter of body surface area with age.

Background. The hanging drop (HD) technique presumably relies on the presence of subatmospheric epidural pressure. It is not clear whether this negative pressure is intrinsic or an artifact and how it is affected by body position. There are few data to indicate how often HD is currently being used. Methods. We identified studies that measured subatmospheric pressures and looked at the effect of the sitting position. We also looked at the technique used for cervical and thoracic epidural anesthesia in the last 10 years. Results. Intrinsic subatmospheric pressures were measured in the thoracic and cervical spine. Three trials studied the effect of body position, indicating a higher incidence of subatmospheric pressures when sitting. The results show lower epidural pressure (−10.7 mmHg) with the sitting position. 28.8% of trials of cervical and thoracic epidural anesthesia that documented the technique used, utilized the HD technique. When adjusting for possible bias, the rate of HD use can be as low as 11.7%. Conclusions. Intrinsic negative pressure might be present in the cervical and thoracic epidural space. This effect is more pronounced when sitting. This position might be preferable when using HD. Future studies are needed to compare it with the loss of resistance technique.

Each of 60 male Ss made 20 judgments of the postural vertical in the absence of visual cues. 10 Ss were randomly assigned to each of the 6 experimental conditions defined by left or right lateral tilt in a prone, supine, or sitting body position. In all conditions Ss consistently underestimated the postural vertical. Significantly larger errors were made by Ss tilted in the sitting position than by Ss tilted in the prone or supine positions. Performance in the prone and supine positions did not differ. No differences were obtained between tilting in the left and right quadrants for any of the body positions. Practice led to a significant decrease in error under all conditions.

In this study, an information system was created to remind users of the length of sitting time to avoid the risk of health problems due to sitting too long. The device is designed and made in two parts, sitting cushion and application on the smartphone. In the seat cushion the limit switch sensor is placed to detect the sitting position and temperature sensor to detect the temperature of the bearing as an indicator of the long sitting. The data detected by the sensor will be sent to the microcontroller and prepared to be sent to the smart phone. The data to be displayed using an android application with Bluetooth communication. Display on the smartphone in human body posture accordance to user's sitting position. There are three body positions, namely the normal position, tilt to the left and tilt to the right. If the body position is tilted, then the smartphone will give an alarm warning to restore the sitting position to the normal position. The bearing temperature detection results will be displayed in the form of numbers with a green background as the indicator of the temperature is still normal, yellow if the bearing temperature rises and red if the temperature has exceeded the permitted normal limit. This means the user has been sitting too long and must stand or rest for a while. To remind the user to stand up, the smartphone will also give a warning by turning on the alarm.
