Effectiveness of Transcutaneous Neuromodulation on Abductor Muscles Electrical Activity in Subjects with Chronic Low Back Pain: A Randomized, Controlled, Crossover Clinical Trial

Introduction: Non-specific chronic low back pain (NSCLBP) is a major cause of functional impairment, resulting in consequences like job absenteeism and reduced quality of life. Risk factors such as muscle weakness and tightness have been implicated. Electromagnetic fields have therapeutic effects on human tissue, including pain relief and muscle relaxation. This study aimed to examine the impact of a tape with magnetic particles (MPT) applied to the lumbar area on abductor muscle strength and surface electromyography (sEMG) of the Gluteus Medius and Tensor of the Fascia Lata muscles in individuals with NSCLBP. Methods: It was carried out a double-blind, randomized, controlled, crossover trial and with test retest, with 41 consecutive patients younger than 65 years who previously diagnosed with NSCLBP to assess the effect of a MPT over hip abductor muscle strength and activity. sEMG and force data were obtained during the Hip Stability Isometric Test (HipSIT). The HipSIT was used to assess the abduction strength using a hand-held dynamometer and sEMG. The HipSIT uses the maximum voluntary isometric contraction (MVIC). Four trials were recorded and the mean extracted for analysis. The tape was applied with either a MPT or a sham magnetic particle tape (SMPT) bilaterally without tension on from L1 to L5 paravertebral muscles. Results: The significant increase in the recruitment of fibers and the significant increase in the maximum voluntary contraction by applying MPT with respect to the SMPT, correspond to the increases in the Peak Force and the decrease in the time to reach the maximum force (peak time) of both muscles. Conclusion: Application of a MPT in patients with NSCLBP suggests an increase in muscle strength of the Gluteus Medius and Tensor Fascia Lata bilaterally during the HipSIT test. Lumbar metameric neuromodulation with MPT improves muscle activation of the hip musculature

Attitudes and beliefs towards low back pain (LBP) among physiotherapists in Spain

Abstract Background The aim of this study is to investigate the attitudes and beliefs of Spanish physiotherapists towards the diagnosis and management of low back pain (LBP). A descriptive, cross-sectional study was conducted according to STROBE guidelines from December 18, 2021, to May 2022. An online survey was developed based on Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT), a reliable and validated self-administered instrument developed to assess the strength of two possible treatment orientations of physiotherapists towards the diagnosis and management of LBP. Respondents were selected through a non-probabilistic convenience sampling technique, and the selection criteria were (1) active physiotherapists with no restrictions on gender and length of service, (2) physical therapists who have worked in both public and private environments, and (3) physiotherapists who have been officially registered with no restriction on the place of practice in Spain. Survey data was obtained and analyzed using the SPSS Statistic 28 (IBM®) statistical software. Results Three hundred eighty-one questionnaires were finally included (F;n=151, M;n=230). In relation to the diagnosis, the respondents indicated that the tissue damage was sufficient to explain widespread and lasting pain, but rather that it was due to psychological factors. In addition, for those surveyed, the diagnosis should not focus exclusively on imaging tests but on clinical symptoms and signs. However, the weak relationship between objective damage and perceived pain intensity, as well as the weak relationship between posture and the development or worsening of LBP, did not seem to be clear to physiotherapists. From the point of view of treatment, we can indicate that professionals are committed to maintaining adequate and individualized physical activity as a first-line treatment in pain management. Conclusions Most physiotherapists in Spain have up-to-date knowledge of the biopsychosocial model of pain care. However, regarding attitudes and beliefs towards LBP, there are still contents and behaviors based on spine protective paradigms that are not conducive to active pain management
