Effect of Pelvic Compression Taping on Lumbo-Pelvic Muscle Activities during Prone Hip Extension

Background: Compression of the sacroiliac joint (SIJ) enables lumbo-pelvic muscles to increase pelvic stability and reduce pain. Many previous studies assessed the effects of pelvic compression belts on the stabilization of the lumbar and SIJs. However, there are a lack of studies to date on the effects of pelvic compression taping (PCT). Objectives: To investigate the effects of PCT on the muscle activity of lumbopelvic muscles during prone hip extension (PHE). Design: Pre-post test design. Methods: In total, 19 healthy male and female participants performed PHE with and without PCT. A surface electromyography system was used to record the muscle activity of multifidus, erector spinae, internal oblique abdominal, and gluteus maximus muscles, and the activities of these muscles before and after taping were compared. Results: During PHE, the activities of the multifidus and erector spinae muscles (P .05). Conclusion: PCT for the SIJ improves the stability of the lumbo-pelvic region, and the use of PCT with functional training would lead to positive clinical effects.

Self-Treatment of Chronic Low Back Pain Based on a Rapid and Objective Sacroiliac Asymmetry Test: A Randomized Open Label Trial

Background: Low back pain (LBP) is common, costly, and disabling. This study assesses a novel and simple LBP evaluation method and its merit in guiding the direction of a self-treatment exercise. Methods: Randomized open label intention to treat study. Consecutive patients with LBP ≥ 3 months and pain ≥ 5/10 were evaluated in a Vancouver clinic with the sacroiliac forward flexion test (SIFFT), which compares the height of posterior superior iliac spines using a level. Those with asymmetry ≥ 5 mm were offered participation. The assistant, who generated and encrypted the randomization, assigned participants: group 1 learned a two-minute, SIFFT-derived, sacroiliac-leveling exercise (SIFFT-E) as needed for LBP relief, group 2 used a pelvic stabilization belt as needed to prevent LBP and group 3 continued usual care. After one month all participants used SIFFT-E and belt as needed for one month. Clinicaltrials.gov # NCT03888235. Trial closed. The Oswestry Disability Index (ODI) (decrease) from baseline to 1 and 2 months was our primary outcome measure. SIFFT improvement (decrease) was also followed. Findings: Of 72 LBP patients, 62 (86%) had ≥5mm asymmetry. Non-exercise control subgroups performed similar statistically. From 0-1 month the 21(one dropout) SIFFT-E participants outperformed the combined 41(one dropout) controls for ODI improvement (12·5±14·8 vs.0·5±14·9 points; mean difference12 points [CI 4·0-20·0]; p=·004 with NNT of 3·2 for improvement of 11 and for SIFFT improvement (7·3±9mm vs.2·1±9mm; mean difference 5·25mm [CI 2·3-10·2mm]; p=·041). At 2 months, after all 62 participants used exercise and belt as needed, ODI and SI asymmetry improvements were clinically significant (12·0±18·4 points (p<·001) and 8·6±8·6mm (p<·001) respectively). Five (8%) exercise and 12(19%) belt wearers experienced mild side effects. Interpretation: Sacroiliac asymmetry was frequent and correctable with SIFFT-guided exercise, resulting in significant improvement in back pain and function. Replication as a larger study is merited.

Pelvic Belt Wearing during Exercise Improves Balance of Patients with Stroke: A Randomized, Controlled, Preliminary Trial

ObjectivesTo investigate whether wearing a pelvic belt during a trunk stability exercise program positively affects balance in patients with stroke. Materials and MethodsTwenty-four patients with stroke were randomly allocated to the experimental or control group and performed a 60-min general physical therapy and an additional 30-min trunk stability exercise (five times/week for 6 weeks). Those in the experimental and control groups performed the trunk stability exercises with and without wearing the pelvic belt, respectively. ResultsThe experimental group showed a significantly greater magnitude of improvements in balance than the control group (Postural Assessment Scale for Stroke: +18.3%, F (1, 22)=14.350, p=.001, η2=.395; Berg Balance Scale: +11%, F (1, 22)=19.062, p=.000, η2=.464; Timed Up and Go Test: −10.5%, F (1, 22)=8.562, p=.008, η2=.280; center of pressure path length with eyes open: −15.1%, F (1, 22)=6.770, p=.016, η2=.235; center of pressure path length with eyes closed: -19.5%, F (1, 22)=9.256, p=.006, η2=.296; center of pressure path velocity with eyes open: -22.6%, F (1, 22)=37.747, p=.000, η2=.632; center of pressure path velocity with eyes closed: −13.9%, F (1, 22)=6.511, p=.018, η2=.228, respectively). ConclusionsWearing a pelvic belt while performing trunk stability exercise programs could be a more effective approach for improving balance in patients with stroke.

Postural Stability in Individuals with and without Sacroiliac Joint Dysfunction Before and After Pelvic Belt Application

Background: Sacroiliac Joint Dysfunction (SIJD) is considered an origin of low-back pain. It can change the motor control strategy and postural control (PC). Objectives: We aimed to find any probable differences in PC between subjects with and without SIJD and determine the effects of the pelvic belt (PB) on PC. Methods: Thirty-eight subjects were assigned into two equal groups with and without SIJD. They started to walk from the place marked on a force plate for 10 seconds after hearing an auditory signal and performed three attempts for each foot. They repeated six more ones with PB. Raw data were imported to an excel software (version 2007) spreadsheet to calculate the reaction time (RT) and anticipatory postural adjustment (APA) as the components of PC. Results: Our results showed a significant difference in RT between the SIJD-affected and non-affected sides (P = 0.035), but there was no significant difference in APA (P = 0.057). There were significant differences in RT and APAs between the control and SIJD-affected side groups (P = 0.001 and P = 0.010, respectively). The PB application showed a significant difference in RT and APAs of the SIJD-affected side (P = 0.001 and P = 0.047, respectively). Conclusions: It seems pain could lead to the postural sway into instability and change the motor control strategy. The proprioception signals from the neuromuscular system of SIJ improved after PB. Therefore, PB, as a feasible tool, can be recommended for PC improvement.

Effects of Trunk Stabilization Exercise While Wearing a Pelvic Compression Belt on Walking and Balancing Abilities in Patients With Stroke

The aim of this study was to investigate the effects of wearing a pelvic compression belt during trunk stability exercise on balance and gait ability in patients with stroke. Thirty-six patients with stroke participated and were randomly allocated to three groups: the paretic group (trunk stability exercise wearing a pelvic belt on the paretic side), the nonparetic group (trunk stability exercise wearing a pelvic belt on the nonparetic side), or the control group (trunk stability exercise without a pelvic belt). Walking and balancing abilities were assessed before and after trunk stabilization exercise. Significantly larger gains were identified in the paretic group than in the control group for all variables (P < 0.017). In addition, significantly larger gains were observed in the paretic group than in the nonparetic group (P < 0.017) (limit of stability, 15.6%; stance phase of paretic side, 4.1%; 10-m walking test, -10.1%; 6-min walking test, 4.6%). Wearing a pelvic belt on the paretic side during trunk stabilization exercise seems to be more effective at improving the balancing and walking abilities of patients with stroke than wearing a pelvic compression belt on the nonparetic side or not wearing a pelvic belt.

The immediate effects of pelvic compression belt with a textured sacral pad on the sacroiliac function in pregnant women with lumbopelvic pain: A cross-over study

BackgroundPelvic belt is being used to alleviate the symptoms of lumbopelvic pain. ObjectiveTo investigate the immediate effects of a pelvic belt with a textured sacral pad in pregnant women with lumbopelvic pain. MethodsTwenty-eight pregnant women participated in a randomized crossover study. Hip joint position sense, maximum hip flexion force, and perceived effort during the active straight leg raising test were measured in twenty-eight pregnant women with lumbopelvic pain. Outcomes were measured in three randomized conditions including no pelvic belt (control), with a pelvic belt, and while a sacral pad was used with the pelvic belt. Data were analyzed using a one-way repeated measures analysis of variance for each variable. ResultsImprovements in all study outcomes have been shown with a pelvic belt compared with the control condition. The addition of a textured sacral pad to the pelvic belt improved all study outcomes compared with the pelvic belt: hip joint position sense (p < 0.001; 95% confidence interval:1.3to2.3), perceived effort (p = 0.003; 95% confidence interval: 0.35 to 1.86), and maximum flexion force (p < 0.001; 95% confidence interval:2.77to6.47) in the active straight leg raising. ConclusionFurther improvements were noted with the addition of the textured pad for all outcome measures. This finding may inform new benefits in adding a textured sacral pad to pelvic compression belts.

Heat Application on Lumbar and Suprapubic Pain During the Onset of Labour Using a New Abdominal Two-Pocket Belt: A Randomised and Controlled Trial

Background: Midwives from the Obstetrics and Gynaecology Unit at University Hospital Germans Trias i Pujol, Badalona, have developed a device for the application of thermal therapy on lumbar and suprapubical areas when labour pain appears. Objective: To assess the beneficial effects of heat application on lumbo-suprapubical pain during initial stages of labour. Study design: Randomized, parallel, open, non-blind clinical trial. Methods: Participants were pregnant women in the prodromal, early and active labour (up to 4-5 cm of dilation), with lumbo-suprapubic pain. The study was conducted in the delivery ward of Hospital Universitari Germans Trias I Pujol, in Badalona (Catalonia, Spain) during 2017-2018. One hundred and thirty-four childbearing women giving birth between September 2017 and March 2018 participated. The intervention group (n=67) received local heat at a temperature between 38-39°C on the lumbo-suprapubic areas for 30 minutes using an elastic pelvic belt as a pain relief device and was compared to a control group in which no heat was used. Primary outcomes were: pain level perception measured with a Visual Analogic Scale and a satisfaction index regarding the utilization of the belt device in the intervention group by using a specific ad-hoc non-validated questionnaire designed for the study. Results: Among the 134 participants: 41% (55) were in prodromal labour, 53.7% (72) in early labour and 5.2% (7) in active labour (up to ≤ 4-5 cm); groups were not balanced for the phases of labour. The pre-intervention pain level in the intervention group was 0.71 points higher (6.28 ± 1.59) than in the control group (5.57 ± 1.87) p=0.02. At 30 minutes of heat application, pain level in the study group decreased 0.65 points (5.88 ± 1.82) while it increased in the control group (6.53 ± 1.85) p=0.046. The difference between basal pain level and post-intervention, was 0.39 ± 1.35 in the intervention group while in the control group it was 0.95 ± 1.11 (p=0.000) in the Visual Analogic Scale. The global satisfaction index for the pelvic elastic belt was 15.38 ± 2.15 (range 5-19) which corresponds to 80.94% over 100% of the maximal punctuation. Conclusion: Heat application on both lumbar and suprapubic areas in case of labour pain is effective in relieving pain. The heat pads subjection device, a new abdominal two-pocket belt, obtained positive feedback from women in the study group who used it and answered the satisfaction questionnaire.

Analysis Regarding the Risk of Injuries of Soldiers Inside a Vehicle during Accidents Caused by Improvised Explosive Devices

This article presents the description of the mechanism of selected dysfunctions of the human skeletal system and internal organs. The problem is wide and requires extensive experimental and numerical research. This article presents the outline of the problem regarding the creation of personal injuries of soldiers inside armored vehicles. The explanation of the mechanism of injuries caused as a result of strong effects of pulse forces, resulting from both the consequences of the wave of pressure created during an explosion, as well as high accelerations of the vehicle’s hull, is presented herein. Examples of the results of numerical analyses of the pressure wave impact from an explosion are presented in the Article. LS-Dyna software was used to perform the numerical calculations. The analyses were carried out using the Conwep algorithm implemented in the calculation code. The significance of calculation methods, thanks to which it is possible to recreate a simulation in which there is a risk of injuries of soldiers without posing a threat to their health and life, should be noted here. The main parts of the human body, such as the bottom limb, the pelvic belt, the cervical spine and the abdomen, have been considered. Mechanisms causing typical injuries of soldiers inside vehicles under which explosives are detonated have been analyzed for particular body parts through multiple numerical simulations. The analysis of the process of injury creation has been conducted on the basis of the statistical data regarding the most common injuries of soldiers. The validation process of numerical analyses was carried out using the results of experimental research.

The effects of pelvic belt use on pelvic alignment during and after pregnancy: a prospective longitudinal cohort study

BackgroundPelvic alignment changes during pregnancy and post-childbirth. Pelvic belts exert external forces that compress and stabilize the joints, and therefore, could influence pelvic alignment. However, limited information is available regarding this potential effect. Therefore, the purpose of this study is to investigate the influence of pelvic belt use on pelvic alignment during and after pregnancy.MethodsData of 201 pregnant women in late pregnancy and 1 month after childbirth were used. Pelvic alignment measurements, including anterior and posterior pelvic width, pelvic asymmetry, and pelvic belt use during and after pregnancy were investigated. Participants were divided into four groups according to pelvic belt use: before and after childbirth (BAC), before childbirth only (BC), after childbirth only (AC), and non-use (NU). Then, an initial one-way ANOVA was conducted to compare the amount of change in pelvic alignment from late pregnancy to post-childbirth between the groups. After the initial analysis, a multivariate regression analysis was performed to determine the statistically significant differences between the groups to consider other factors that influenced pelvic alignment such as age, BMI, number of previous childbirths, vaginal delivery and pelvic asymmetry in late pregnancy. Next, a cutoff point for subgroup stratification based on the weekly duration of pelvic belt use and inter-group changes in pelvic alignment were compared.ResultsAs the result of the initial one-way ANOVA, the decrease in pelvic asymmetry from during pregnancy to postpartum for BAC was greater than that for AC. Moreover, multiple regression analysis showed that the effect of pelvic belt that was revealed in the initial analysis was statistical significance even after adjustment for other factors. Moreover, pelvic asymmetry in the BAC group decreased, compared to being increased or unchanged in the NU and AC groups when the group cutoff time was 7 h per week.ConclusionsContinuous and extended use of pelvic belts during and after pregnancy might be related to modifications of pelvic asymmetry in the perinatal period. Therefore, the instruction of correct and comfortable usage and the recommendation of continuous use of pelvic belt especially during pregnancy are required for prevention of some discomforts related to pelvic malalignment.

Effect of pelvic belt on the perception of difficulty and muscle activity during active straight leg raising test in pain-free subjects

A pelvic belt decreases patient-reported perception of difficulty during the active straight leg raising (ASLR) test in individuals with pelvic girdle pain. However, the influence of a pelvic belt on the perception of difficulty during ASLR was not investigated in pain-free subjects. Therefore, this influence excluding the impact of pain is not clear. This paper aimed to clarify the effect of a pelvic belt on the perception of difficulty and muscle activity during ASLR performance in the subjective heavier side leg in pain-free subjects. Twenty pain-free female subjects participated. ASLR using the subjective heavier side leg was performed under two conditions: without and with a pelvic belt. Muscle activation of the external oblique, internal oblique, rectus abdominis, rectus femoris, and biceps femoris was measured during ASLR using a surface electromyograph. Difference in perceived difficulty in performing ASLR with and without a belt was assessed. In total, 80% of subjects had decreased perception of difficulty using a pelvic belt during ASLR. For ASLR performed with a pelvic belt, muscle activity significantly decreased in the contralateral rectus abdominis, ipsilateral external oblique, and bilateral internal oblique (P<0.05), while it significantly increased in the contralateral biceps femoris (P<0.05). There were no significant differences in muscle activity of the ipsilateral rectus abdominis, contralateral external oblique, and ipsilateral rectus femoris between the two conditions (P>0.05). In conclusion, using a pelvic belt can decrease the perception of difficulty during ASLR, and the pelvic belt may improve impairment of load transfer between the trunk and pelvis.

The Presence of Acinetobacter baumannii DNA on the Skin of Homeless People and Its Relationship With Body Lice Infestation. Preliminary Results.

The presence of Acinetobacter baumannii was demonstrated in body lice, however, little is known about the mechanism of natural lice infection. In 2013 and 2014, cross-sectional one-day studies were therefore performed within two Marseille homeless shelters to assess the presence of A. baumannii DNA on human skin, blood and in body lice collected from the same homeless individuals. All 332 participants completed questionnaires, were examined for dermatologic signs, and provided four skin samples (hair, neck, armpits, and pelvic belt), blood samples and body lice (if any). We developed a new real-time PCR tool targeting the ompA/motB gene for the detection of A. baumannii for all collected samples. Blood culture was also performed. Body lice were found in 24/325 (7.4%) of subjects. We showed a prevalence of A. baumannii DNA skin-carriage in 33/305 (10.8%) of subjects. No difference was found in A. baumannii DNA prevalence according to body sites. A strong association between body lice infestation (OR = 3.07, p = 0.029) and A. baumannii DNA skin-carriage was noted. In lice, A. baumannii DNA was detected in 59/219 arthropods (26.9%). All blood cultures and real-time PCR on blood samples were negative for A. baumannii. Lice probably get infected with A. baumannii while biting through the colonized skin and likely transmit the bacteria in their feces. We found no evidence that lice facilitate the invasion of A. baumannii into the blood stream. Further investigations are needed to compare phenotypic and genotypic features of A. baumannii isolates from human skin and lice from the same individuals.

Walking With a Weighted Pelvic Belt or With an Equivalent Pure Downward Force on the Pelvis: Are These Different?

In a previous study, a tethered pelvic-assist device (TPAD) was used to successfully retrain crouch gait in children with cerebral palsy by applying a downward force on the pelvis while walking on a treadmill. While the results of this study were promising, an important issue was to translate this training to the children in a more practical manner. This motivated the question in this letter whether a different intervention could result in similar improvements in the gait as seen with the TPAD. This is the motivation for this study, which compares the biomechanical differences in walking under the following two conditions. 1) The TPAD applies a pure downward force on the pelvis using tethers. 2) A weighted pelvic belt is used to apply the same downward force on the pelvis. In this case, the weight belt also increases the mass at the pelvis. A total of ten healthy subjects performed two separate experiments while walking on an instrumented treadmill. The whole-body kinematics were recorded using a motion-capture system, and the ground reaction forces were measured by the force plates embedded in the treadmill. We found no significant differences in the kinematic gait parameters of healthy subjects when the downward force, equivalent to 15% body weight, applied by the TPAD was replaced by a weighted pelvic belt having 15% body weight. However, the activation of the gastrocnemius muscle and the estimated maximum ankle torque, predicted by an inverted pendulum mathematical model, during the single support phase of walking, showed a higher increase with the weight belt when compared to a pure downward force. Thus, the weight belt, because of its simplicity, must be further considered as a more convenient candidate to translate the results of TPAD in children with cerebral palsy who suffer from crouch gait.

Efficacy of Sacro-Occipital Technique on Sacroiliac Joint Instability in Females

AbstractBackground: Sacroiliac function is considered to be important in many manual therapy systems because of the complexity and location of the Sacroiliac joint in the kinetic chain, moreover 98% of patients having low back pain had mechanical dysfunction of the sacroiliac joints.Aim of Study: The aim of this study is to explore the effect of Sacro-occipital technique on pelvic obliquity in patients with Sacroiliac joint instability.Patients and Methods: Thirty female patients were ran-domly assigned into two groups and each group consists of 15 patient. Control Group (A) treated by Therapeutic ultrasound and study Group (B) treated by Sacro-occipital technique + Pelvic belt + Therapeutic ultrasound. Referred from orthopedist with the diagnosis of Sacroiliac joint pain with mean age, weight and height 29.5 (3.8) years, 74.7 (5.3) kg, and 163 (4.4) cm respectively. Pelvic obliquity was objectively meas-ured by using pelvic inclinometer.Results: No statistically significant difference between groups in pelvic obliquity before treatment. But a significant reduction in pelvic obliquity was observed in the study group (B) compared to the control group (A).Conclusion: The study proved that Sacro ocipital technique decreased the pelvic obliquity in patient with sacro iliac joint instability.
