Abstract:
Postoperative spinopelvic changes are associated with increased dislocation risk following total hip arthroplasty (THA). The aim of this study was to identify preoperative patient and radiographic factors associated with high-risk postoperative spinopelvic parameters. A retrospective review of consecutive THA patients who received preoperative and postoperative sitting and standing lateral lumbar spine-hip radiographs with minimum radiographic and clinical follow-up of 10 months was performed. Patient demographics were recorded and preoperative standing and sitting sacral slope (SS), anteinclination, pelvic femoral angle (PFA), and combined sagittal index (CSI) were measured. High-risk patients were defined by decreased spinopelvic motion (∆SS from sitting to standing of >10°), increased hip motion (∆PFA from sitting to standing of >10°), or decreased CSI of >10° at final follow-up compared with preoperative measurements. Univariate and multivariate regression analyses were used to identify preoperative demographic and radiographic factors associated with these high-risk categories. One hundred and fifty-three patients were included with an average age of 62 years, average body mass index of 27.8 kg/m2 , and average follow-up of 16.2 months. At 1-year follow-up, 43 (28.1%) patients demonstrated a decreased ∆SS > 10° and 67 (43.7%) patients demonstrated an increased ∆PFA > 10° compared with preoperative values. Sitting CSI decreased by >10° in 17 (11.1%) patients. Preoperative increased sitting PFA (adjusted odds ratio [aOR] 1.057, p < 0.001) and decreased preoperative hip motion (∆PFA) were associated with decreased sitting CSI of >10° at 10-month follow-up. Increased spinopelvic motion (∆SS) and decreased hip motion (∆PFA) preoperatively are associated with postoperative radiographic changes that be associated with increased dislocation risk.Keywords:

[Purpose] This study investigated the effect of functional electrical stimulation (FES) of stroke patients in a sitting position on balance and activities of daily living. [Methods] FES was applied to stroke patients (six male, three female) while in a sitting and supine position. FES was applied six times for 30 minutes each for a total of six weeks. [Results] The timed up and go (TUG) values at weeks 2, 4, and 6 after FES treatment in a sitting position were noticeably decreased in a time-dependent manner, compared with controls. In the sitting, the functional reach test (FRT) values were significantly increased in a time-dependent manner. The same values in the supine position weakly showed a similar pattern to those in the sitting position. Furthermore, the functional independent measurement (FIM) values in the sitting position were markedly increased in a time-dependent manner. In the sitting position, the intensity of FES was markedly decreased in a time-dependent manner. The same values in the supine position weakly showed a similar pattern to those in the sitting position. [Conclusion] These results suggest that the conditions of stroke patients in both the sitting and supine positions after FES treatment were improved and that FES had a greater effect in the sitting position.

The purpose of this paper is to clarify the sitting behaviors of visitors of art museums in a day of outing activities. We conducted a questionnaire survey to analyze three items, the numbers of sitting periods, the time of sitting and the sitting places. The results are as follows : The average numbers of sitting periods correlate with that of visiting; The average time of sitting of stay is closely related to that of stay, 20〜25% of that; The users who stayed in the department store, the shopping center, etc tend to sit in other places.

The purpose of this study was to investigate the change in blood pressure while sitting up and standing up to obtain basic data for the management of risk in the clinical physical therapy setting. The subjects in Experiment 1 ( sitting up ) were 9 healthy young people ( 21.6±0.7 years old ) and those in Experiment 2 ( standing up ) were 11 healthy young people ( 24.4±6.1 years old). Systolic ( SBP ) and diastolic blood pressures ( DBP ) were measured beat by beat at the right radial artery with a continuous blood pressure measuring apparatus while the subjects were sitting up or standing up. The maximal value of SBP while sitting up increased. The minimal values of SBP and DBP decreased significantly compared with those at rest. The maximal values of SBP and DBP increased and the minimal values of SBP decreased significantly while standing up from a sitting height of 20 cm. Blood pressure fluctuated in a range of about 40mmHg in the process of sitting up and standing up. These results indicate that physical therapists should manage the risk of changes in blood pressure carefully when they have their patients practice sitting up and standing up.

We analyzed questionnaire on the sitting position among neurosurgeons. We sent questionnaire to 80 medical colleges in Japan and obtained response from 61 universities (76.3%). The sitting position surgery was performed in 7 institutions (11.5%) and was not in other 54 (88.5%). The first reason for not adopting the sitting position was "other position was good enough to perform the surgery" (44 institutions, 81%). This reason exceeded "objection from the anesthesiologist" (17 institutions, 31%). Twenty institutions (33%) adopted or wished to perform the surgery in sitting position, indicating that neurosurgeons still are interest in performing the sitting position surgery. But 6 institutions adopting the sitting position predicted that the sitting position would diminish in the future, and the sitting position surgery would decrease in number in Japan.

For testing the influence of the examination position on the parameters of the urethrocystometry 124 findings of urethrocystometry of 103 female patients were evaluated in 3 groups. In these cases slight alterations develop when changing between lying and sitting position, whereby in sitting position a greater differentiation of an existing component of stress incontinence becomes possible. On the basis of our examination findings and the references in literature it seems to be advisable to perform the urethrocystometry in the same session both in lying and in sitting position for further improvement of the indication for therapy.

Ersoy S, Pinar R, Ersoy IH. International Journal of Nursing Practice 2011; 17 : 105–109 Changes in blood pressure in the sitting and standing positions in hypertensive patients Most guidelines for management of hypertension do not give special preference to a specific position of patient during blood pressure (BP) measurement, suggesting that BP readings taken with patients sitting, supine and standing are equivalent. The objective of this study was to examine whether there was any difference between BP readings with hypertensive participants comfortably sitting on chair and those with participants standing with the arm supported horizontally at the right atrial level. BP was measured twice each for 168 hypertensive patients (medicated and unmedicated) at sitting, standing and sitting positions, respectively, with a mercury‐filled column sphygmomanometer. We found significantly lower in systolic and diastolic BP readings in standing position than in sitting position. The present study indicates that the BP readings are related to the posture; thus, BP measured in different positions cannot automatically be regarded as equivalent.

Introduction. The development of modern technology has changed human lifestyle from active to passive (sitting). According to many authors, prolonged sitting is a risk factor for overextension and painful conditions of the spine. However, it seems that this relationship can only occur in conjunction with other factors. The aim of this study is to assess a sitting position using a kyphotisation indicator constructed by the author. Material and methods. The study included 372 people living and working professionally in the Silesian Voivodeship. The research program consisted of an interview survey and measurements the length of the spine projections, which provided the calculation of a kyphotisation indicator. Results. The conducted assessment showed that the examined people receive automatically a kyphotic sitting position and this postural habit is moved to a standing position. In addition, the study highlighted the 2 types of habitual sitting positions, one with a higher kyphotisation indicator and the other with a lower kyphotisation indicator, reflecting the “dynamic” sitting and searching a comfortable (antalgic) sitting position by the researched people. Conclusions. A kyphotic sitting position is a risk factor for overextension and painful conditions of the spine, and the kyphotisation indicator can be a useful tool for further clinimetric research regarding a sitting position.

We define the facilities for visitors to use on foot. As one of them, we survey 5 art museums to study the visitors' sitting behaviors. The results are as follows : The users' situations before and after visiting art museums, have effects on sitting behaviors. There is a high correlation coefficient between the rate of the number of users' not sitting, and the average of times of users' sitting. Sitting behaviors are influenced by the length of the users' stay and the length of the users' not sitting before arriving.

The effect of rewarding desirable sitting positions in six children with cerebral palsy (mean age of 3.7 years) was examined. Each subject's sitting behavior was documented at home under both pretreatment and treatment conditions. Treatment of all subjects consisted of rewarding the use of positions other than the reverse tailor sitting position. In addition, half of the subjects were asked to sit in desirable positions. All subjects demonstrated significant increases in the frequency and duration of desirable sitting positions after the onset of treatment. Those children asked to sit in desirable positions showed even greater increases, but only initially. Sitting behavior was documented (but not treated) in another setting, before and after treatment was instituted in the home. Four subjects showed some increases in the frequency of desirable sitting in the other setting. Further research is suggested in the management of reverse tailor sitting at home and in school.
