Proper sitting posture means keeping both feet flat on the floor, aligning your back with the back of your chair and keeping your shoulders straight. What is Proper Sitting Posture? Use these tips to find out:. Your body can only tolerate being in one position for about 20 minutes before it starts to feel uncomfortable. In order to keep your balance on the ball, you will have to sit up straight with both feet on the floor, which will give you an idea of what good sitting posture should feel like.
Finally, you can reduce the strain that comes from sitting all day an unnatural position for the human body when done in long periods by stretching. Check out these nine simple stretches to do right at your desk. And remember that you can reduce muscle tension, increase your flexibility and improve your posture overall by making stretching a regular part of your day. The great thing about stretching is that once you incorporate it into your routine, it will make sitting at your desk much easier on your body.

Between two consecutive measurements, the patient was asked to relax for 5 minutes. To reduce measurement biases, BP was assessed using an automatic oscillometric device Omron M6 Comfort HEME; Omron M2 Basic, Lacchiarella, Italy with an appropriate standard bladder arm circumference related, as indicated by the instruction manual. The instrument was clinically validated by the British Hypertension Society.
The nine BP measurements were made in different order and in different positions. To avoid potential bias related to the order of the measurement, the sequence of the triplets was chosen at random and different for each patient. Specific tables were created containing a computer generated random sequence of each position, and a different random table was used for each patient. In addition to BP, the following variables were measured by the nurse: height bare foot and weight underwear , heart rate which is automatically measured by the oscillometric device during each BP measurement , and arm circumference naked arm.
The body mass index BMI was then computed as the rate between weight in kilograms and the square of the height in meters. The study protocol was approved by the local ethics committee Record no. Sample size calculation. The main aim of the study was to detect a clinically relevant variation in SBP and DBP measurements in three different positions. The required sample size was subjects, and individuals were conservatively enrolled.
Data analysis. The differences in either SBP and DBP according to the position have been initially investigated using Wilcoxon-matched-pairs signed-ranks test, separately for each comparison. The independent association between the position of the measurement and BP has been evaluated using two separate generalized estimating equations models: 21 the first with SBP as the dependent variable; the second with DBP. Both models were set as repeated regression analyses, using patient's id as the cluster level, and fitted assuming an exchangeable correlation structure, with robust standard errors based upon sandwich estimator.
We also fit two random-effect regression models, with smaller standard errors but no appreciable differences in coefficients and P values, and conservatively opted to show generalized estimating equations results only. To investigate the degree of random variation in BP, the same approach was used to compute the percentage of subjects with large differences in BP according to the order of the measurement within each position.
The mean age of the hypertensive participants was The average SBPs were The mean DBPs showed an opposite trend: it was highest in sitting position The variability of mean BP by position was evaluated in six comparisons: supine vs. Fowler's; supine vs. However, all the differences were statistically significant at either univariate or multivariate analysis, with the exception of the difference in SBP between Fowler's and sitting positions Table 1.
Matrix showing the results of the six comparison between mean systolic or diastolic blood pressures as measured in three body positions univariate analysis. The results of multivariate analyses have been detailed in Table 2. As compared with supine position, the SBP measured in Fowler's and sitting positions decreased of 1. By contrast, DBP increased of 1. Notably, the order of the measurement within each position was also associated with a decrease in BP: compared with the first measurement, both the second and the third showed significantly lower values of either SBP or DBP.
No differences in BP were observed according to heart rate. Results of the four generalized estimating equations models predicting systolic SBP and diastolic DBP blood pressure patient's id as the cluster.
Only 4. Table 3 also shows the proportions of subjects with large differences in BP according to the order of the measurement.
Concerning SBP, almost one-third of the sample showed a large difference in at least one comparison first vs. The percentages of subjects with large variations in DBP was lower; the highest being To explore whether the appearance of large differences could be associated with the order of the measurement, both comparisons by position and by order were repeated using order categories Table 3. In any position, the highest rates of large differences were observed at the first measurement, and when the first and third measurements were compared.
Several studies compared BP values when measured in sitting or supine positions, reporting variations which ranged from 0 to a maximum of 10mmHg. This is of particular relevance because BP differences may impact much more on hypertensive than normotensive subjects, as the clinical management of hypertension is largely based upon BP measurements.
Quantifying random variability in BP measurements may be important to verify whether it may confound the association between BP and body position, and whether more than one recording at each BP measurement is really needed.
On one side, our multivariate analyses showed very little influence of random variability as roughly measured by the change in BP according to the order of measurement on the differences between supine, sitting, and Fowler's BP, which were strongly significant even after adjusting for measurement order and heart rate.
Although it is true that a relatively large variability has been observed across all measurements, taking the mean value between two measurements reduces the possibility of a large measurement error or a large random variation. Given that two measurements are not always taken in routine clinical practice, operators should be informed of the importance of this procedure and more emphasis on the topic should be given in their educational pathway.
The potential clinical implications of the above findings deserve some further consideration. Indeed, besides statistical significance, if only the average difference from one position to another is considered, the clinical relevance of the BP variations according to body position may be of limited clinical importance, because the mean differences in both SBP and DBP across positions never exceeded 2.
However, this fact may easily be the result of positive and negative differences which tend to cancel each other out if only mean values are examined, leaving relatively small mean differences. Therefore, in the clinical management of hypertensive subjects, if BP is measured before therapy in one position and after therapy in another position, the clinician may opt for imprecise or incorrect therapeutic strategies in a relevant proportion of subjects.
Accordingly, it may be indicated to measure the BP in the same position throughout the overall duration of the therapy.
