Virtual reality to improve low-back pain and pelvic pain during pregnancy: a pilot RCT for a multicenter randomized controlled trial

A significant proportion of women experience low back and pelvic pain during and after pregnancy, which can negatively impact their daily lives. Various factors are attributed to these complaints, and many affected women do not receive adequate healthcare. However, there is evidence to support the use of different physiotherapeutic interventions to alleviate these conditions. Virtual reality is a promising complementary treatment to physiotherapy, particularly in improving pain perception and avoidance. The primary objective of this study is to evaluate the efficacy of a four-week program combining VR and physiotherapy compared to standard physiotherapy in pregnant women with low back and pelvic pain, in terms of improving pain avoidance, intensity, disability, and functional level. The study also aims to investigate patient satisfaction with the VR intervention. This research will be conducted through a multi-center randomized controlled clinical trial involving pregnant patients residing in the provinces of Seville and Malaga with a diagnosis of low back and pelvic pain during pregnancy. The alternative hypothesis is that the implementation of a Virtual Reality program in combination with standard physiotherapy will result in better clinical outcomes compared to the current standard intervention, which could lead to the development of new policies and interventions for these pathologies and their consequence

Adherence to home exercises in non-specific low back pain : a randomised controlled pilot trial

Specific exercises for the improvement of movement control of the lumbopelvic region are well-established for patients with non-specific low back pain (NSLBP) and movement control impairment (MCI). However, a lack of adherence to home exercise regimens is often observed. The aim of the study was to explore the differences in home exercise (HE) adherence between patients who perform conventional exercises and those who exercise with Augmented Feedback (AF). Twenty patients with NSLBP and MCI were randomly allocated into two groups. The physiotherapy group (PT group) completed conventional exercises, and the AF group exercised with an AF system that was designed for use in therapy settings. The main outcome measure was self-reported adherence to the home exercise regimen. There was no significant difference in HE duration between the groups (W = 64, p = 0.315). The AF group exercised for a median of 9 min and 4 s (IQR = 3'59"), and the PT group exercised for 4 min and 19 s (IQR = 8'30"). Exercising with AF led to HE times that were similar to those of conventional exercise, and AF might be used as an alternative therapy method for home exercise

An investigation into the utility of wearable sensor derived biofeedback on the motor control of the lumbar spine

Lower back pain (LBP) is a disability that affects a large proportion of the population and treatment for this has been shifting towards a more individualized, patient-centered approach. There has been a recent uptake in the utilization and implementation of wearable sensors that can administer biofeedback in various industrial, clinical, and performance-based settings. The overall aim of this Master’s thesis was to investigate how wearable sensors can be used in a sensorimotor (re)training approach, including how sensory biofeedback from wearable sensors can be used to improve measures of spinal motor control and proprioception. Two complementary research studies were completed to address this overall aim. As a systematic review, Study #1 focused on addressing the lack of consensus surrounding wearable sensor derived biofeedback and spine motor control. The results of this review suggest that haptic/vibrotactile feedback is the most common and that it is administered in an instantaneous real-time manner within most experimental paradigms. Further, study #1 identified clear gaps within the research literature. Specifically, future research would benefit from more clarity regarding study design, and movement instructions, and explicit definitions of biofeedback parameters to enhance reproducibility. The aim of Study #2 was to assess the acute effects of wearable sensor-derived auditory biofeedback on gross lumbar proprioception. To assess this, participants completed a target repositioning protocol, followed by a training period where they were provided with auditory feedback for two of four targets based on a percentage of their lumbar ROM. Results suggest that mid-range targets benefitted most from the acute auditory feedback training. Further, individuals with poorer repositioning abilities in the pre-training assessment showed the greatest improvements from the auditory feedback training. This suggests that auditory biofeedback training may be an effective tool to improve proprioception in those with proprioceptive deficits. Collectively these complimentary research studies will improve the understanding surrounding the ecological utility of wearable sensor derived biofeedback in industrial, clinical, and performance settings to enhance to sensorimotor control of the lumbar region

Adhésion à un programme d’exercices à domicile pour la lombalgie non-aiguë : une étude observationnelle.

Introduction : Les données probantes reconnaissent que les exercices constituent une modalité curative pour traiter la lombalgie non-aiguë. Or, les effets sont modestes, ce qui amène la communauté scientifique à se questionner, entre autre, sur le niveau d’adhésion des patients à leur programme d’exercices à domicile. Cette étude poursuit deux objectifs : (1) explorer l’association entre l’adhésion à un programme d’exercices à domicile et les variables de résultats (primaires : douleur, incapacité ; secondaires : les changements globaux, le sentiment d’efficacité personnelle, la détresse psychologique), (2) explorer l’association entre l’adhésion à ce programme et les principales variables biopsychosociales sur lesquelles le thérapeute peut agir, en utilisant un cadre théorique explicatif incluant : le modèle de peur-évitement, le modèle du sens commun et le concept de l’alliance de travail. Méthode : Une cohorte longitudinale de volontaires de 48 adultes ayant une lombalgie (> 4 semaines) a été recrutée. L’adhésion au programme d’exercices à domicile et les autres facteurs biopsychosociaux ont été mesurés par des questionnaires auto-administrés au début, après quatre semaines, à la fin des huit semaines de traitement et six mois plus tard. Des analyses univariées et multivariées ont été menées. Résultats : Pour le premier objectif, les modèles linéaires mixtes démontrent que l’adhésion est seulement associée aux variables de résultats secondaires. Pour le second objectif, 50 % de la variance de l’adhésion (ICC = 50,00, p < 0,001) a été expliquée par sept variables, les changements globaux ayant la plus forte association avec l’adhésion. Les changements globaux, à leur tour, ont été expliqués par cinq variables (ICC = 22,3, p = 0,028), les représentations ayant la plus forte association. Les représentations ont été expliquées par cinq variables pouvant être incluses dans le modèle peur-évitement (ICC = 49,2, p < 0,001). L’alliance de travail n’était pas associée à l’adhésion. Conclusion : Les variables de résultats secondaires devraient s’ajouter aux variables de résultats primaires dans les études portant sur l’adhésion aux exercices. Le modèle du sens commun a été utile pour expliquer les variables associées à l’adhésion. Le modèle de peur-évitement a été davantage utile pour expliquer les variables associées aux représentations qui sont au cœur du modèle du sens commun
