Effects of global postural reeducation on postural control, dynamic balance, and ankle range of motion in patients with hallux abducto valgus. A randomized controlled trial.

AbstractHallux abducto valgus (HAV) is a common musculoskeletal disorder that has been addressed surgically. Nevertheless, the manual therapy approach may play an important role in the management of this condition. The present study aimed to determine the effectiveness of global postural reeducation (GPR) in subjects with symptomatic mild to moderate HAV in static postural control, dynamic stability, and ankle dorsiflexion range of motion (DFROM). A total of 80 patients with mild to moderate symptomatic HAV were allocated to the intervention group (GPR) or control group (CG) (no treatment) for 8 weeks. Outcome measures were assessed at baseline at 4 and 8 weeks including static postural control (Romberg test), dynamic balance (Star Excursion Balance Test [SEBT]), and ankle DFROM (Weight‐Bearing Lunge Test [WBLT]). No improvements were observed at 4 weeks, but there were improvements at 8 weeks in: static postural control mediolateral displacement (X) of center of pressure (CoP) in both eyes open (EO) and eyes closed (EC): XEO (t(36) = 2.892, p = .006, d = 0.67); XEC (t(68) = 2.280, p = .026, d = 054); and velocity (V) of CoP displacement: VEO (t(68) = 2.380, p = .020, d = 0.57); VEC (t(36) = 2.057, p = .047, d = 0.37). It were also improvements in: WBLT (t(36) = −2.869, p = .007, d = 0.54) and SEBT at three directions (anterior, ANT; posteromedial, PM; and posterolateral, PL): SEBT.ANT (t(36) = −2.292, p = .028, d = 0.23); SEBT.PM (t(36) = −4.075, p < .001, d = 0.43); SEBT.PL (t(62) = −3.506, p = .001, d = 0.34). The present study showed that GPR compared to the CG might be effective in enhancing ankle function including postural control, dynamic balance, and DFROM

Manual therapy versus therapeutic exercise in non-specific chronic neck pain: study protocol for a randomized controlled trial

Background The underlying mechanisms of non-specific chronic neck pain relapses are not clear, but they could be associated with a deficit and alteration of neck muscles propioception that play a decisive role in cervical joint position, motor control of the head, and postural stability. Numerous treatments for non-specific chronic neck pain have been described in the scientific literature. However, few studies analyze its influence on postural stability, since these alterations are not fully described, and various theories emerge about the reasons that cause it. Our primary aim is to analyze the differences in postural stability, pain, cervical disability, and the relation between them produced by a treatment based on manual therapy and another based on therapeutic exercise. Methods The short-term and mid-term changes produced by different therapies on subjects with non-specific chronic neck pain will be studied. The sample will be randomly divided into three groups: manual therapy, therapeutic exercise, and placebo. As dependent variables of the study, we will take (1) Overall Balance Index, measured through a dynamic stabilometric platform; (2) pain, based on the visual analog scale and the Pressure Pain Threshold; (3) cervical disability, through the neck disability index. The findings will be analyzed statistically considering a 5% significance level (p ≤ 0.05). Discussion Our study aims to provide knowledge about postural stability and its relationship with pain in subjects with non-specific chronic neck pain. Analyzing the results produced by different types of therapy will allow us to draw conclusions about the mechanisms, structural or central, that may elicit these alterations

Relationship between Respiratory Muscle Function and Postural Stability in Male Soccer Players: A Case-Control Study

The important role of postural stability in exercise performance has been determined by several authors. Despite this, few studies have analyzed the relationship between respiratory muscles’ strength and postural stability in athletes. For this reason, the aim of this study was to investigate the relationship between postural stability and respiratory muscles’ function in male soccer players. A case-control study was conducted over twenty-eight healthy men (18 soccer players; 10 non-athletes). Inspiratory muscle strength (MIP) and respiratory resistance (MVV) were obtained through a digital spirometer. Stability variables were obtained in standing position on a stabilometric platform and in open and closed eyes conditions. The area and length of the center of pressures and displacements in the X and Y range were analyzed. Pearson’s coefficient was used to measure the linear correlation between MIP, MVV and stabilometric variables. In the soccer players’ group, MIP and MIP % predictive were inversely correlated with length (r = −0.535 and r = −0.585; p &lt; 0.05) and X range (r = −0.527 and r = −0.560; p &lt; 0.05), whereas MVV was directly correlated with length (r = 0.606; p &lt; 0.01) and Y range (r = 0.558; p &lt; 0.05). Our results show that the greater the inspiratory muscle strength, the less displacement of the pressure center, while at higher respiratory rates there is greater displacement
