Plantar Pressure Changes and Their Relationships with Low Back Pain during Pregnancy Using Instrumented Insoles

Low back pain affects around 50% of pregnant women and presents significant morbidity and persistence for years in 20% of postpartum women who report that pain. Numerous studies have documented gait alterations during pregnancy and postpartum. Therefore, an analysis of the relationship between certain gait parameters and low back pain was attempted using low-cost validated instrumented insoles. This work presents a longitudinal cohort study carried out during routine gynecological follow-up visits in the first, second, and third trimesters of pregnancy at an Obstetrics and Gynecology Service. Sample size was 62. Plantar pressure data were collected with specially designed instrumented insoles containing four force sensors to measure peak pressure, center of pressure, and stance phase time in each foot and in each pregnancy trimester. The analysis was carried out on a two-dimensional level, simultaneously considering the data from both feet using Hotelling’s T2 test. This longitudinal study detected relationships between certain gait parameter changes and low back pain during pregnancy. It revealed a cyclic tendency of low back pain prevalence with a maximum in the second trimester and a decrease in the third trimester, which was correlated with alterations of the pregnant gait: excessive foot pronation and rearfoot pressure increase.

Acceptable Measure

IntroductionCompleteness of Global Burden of Disease (GBD) Study data is acknowledged as a limitation. To date, no study has evaluated this issue for low back pain, a leading contributor to disease burden globally.MethodsWe retrieved reports, in any language, based on citation details from the GBD 2017 study website. Pairs of raters independently extracted the following data: number of prevalence reports tallied across countries, age groups, gender and years from 1987 to 2017. We also considered if studies enrolled a representative sample and/or used an acceptable measure of low back pain.ResultsWe retrieved 488 country-level reports that provide prevalence data for 103 of 204 countries (50.5%), with most prevalence reports (61%) being for high-income countries. Only 16 countries (7.8%) have prevalence reports for each of the three decades of the GBD. Most of the reports (79%) did not use an acceptable measure of low back pain when estimating prevalence.ConclusionWe found incomplete coverage across countries and time, and limitations in the primary prevalence studies included in the GBD 2017 study. This means there is considerable uncertainty about GBD estimates of low back pain prevalence and the disease burden metrics derived from prevalence.

Nonlinear Parameters

The characteristics of postural sway were assessed in quiet standing under three different postural task conditions in 14 patients with nonspecific chronic low back pain and 12 healthy subjects using linear and nonlinear center of pressure parameters. The linear parameters consisted of area, the mean total velocity, sway amplitude, the SD of velocity, and the phase plane portrait. The nonlinear parameters included the Lyapunov exponent, sample entropy, and the correlation dimension. The results showed that the amount of postural sway was higher in the patients with low back pain compared with the healthy subjects. Assessing the nonlinear parameters of the center of pressure showed a lower sample entropy and a higher correlation dimension in the patients with low back pain compared with the healthy subjects. The results of this study demonstrate the greater regularity and higher dimensionality of the center of pressure fluctuations in patients with nonspecific chronic low back pain, which suggests that these patients adopt different postural control strategies to maintain an upright stance.

Purpose: The present study was undertaken to find out the relationship among outcome variables as well as association between dependent variables with physical characteristics in low back pain (LBP) patients. Correlations between outcome variables [pain, back pressure changes (BPC), abdominal pressure changes (APC), walking, stairs climbing, stand ups, quality of life (QOL) and sexual frequency] of all LBP subjects before and after treatment were assessed. Regression analysis was used to estimate baseline BPC and APC of LBP subjects from their baseline demographic characteristics (age, height, waist circumference, systolic blood pressure, and pulse rate) and severity of pain. Methods: A total of 141 nonspecific chronic LBP patients were recruited. After baseline recording, all subjects were given trunk stabilization training for 20 regular days. After training, the follow-up was done at a gap of each 15 days up to 6 months (180 days). At the last follow-up session (180th day), the outcome variables were recorded again. Findings: The present study found an inverse relation between pain and muscle functions (BPC: r = -0.36; p < 0.01 and APC: r = -0.26; p < 0.01). This study also showed that BPC was more inversely related with the pain than APC. Conclusions: This study concludes that physical strength (BPC and APC) of LBP subjects is more closely associated with the pain than the functional ability (walking, stairs climbing and stand ups). This study also estimated (baseline or before treatment) BPC and APC in LBP subjects from their physical characteristics and pain severity.
