“…Our study also produced a similar result, and we verified increased muscle activities of the lumbar erector spinae after IT. This signified that muscle tension persisted even after IT 10 ) . These results concur with those of a study by Wang et al 5 ) showing that IT causes muscle fatigue.…”

[Purpose] The purpose of this study was to analyze changes in the electromyographic activities of the lumbar erector spinae caused by inversion traction in order to verify the relaxation effect. [Subjects and Methods] The subjects included 60 healthy male adults who were equally and randomly assigned to a 30–30° group, a 30–60° group, and a 60–60° group. Inversion traction was performed for six minutes, and the electromyographic activities of the lumbar erector spinae (L2, L4) were measured before and after inversion traction. [Results] The root mean square values at the L2 and L4 levels on both sides were statistically significantly higher after inversion traction compared with before inversion traction. Before inversion traction, the root mean square values at the L2 and L4 levels on both sides in the 30–60° group and 60–60° group were significantly higher than those in the 30–30° group, while the root mean square values at the L2 and L4 levels on both sides showed no significant differences between the groups before inversion traction. [Conclusion] The findings of this study indicated that IT is more likely to elicits an increase in muscle tension and prevent relaxation of the lumbar erector spinae.

“…12. The reason is that the operating pressure for the lab test was selected based on the reviewed literature on the range of pressure that can be applied to the neck by pneumatic neck support to deliver muscle relaxation [15] and [16]. So, the lab testing was not tested to the far end of the stress capacity of the prototype.…”

Tension Neck Syndrome Musculoskeletal Disorder (TNS MSD) causes discomfort in the muscles around the neck and shoulder, especially of the elderly. It is one of the leading causes of early retirement. This paper provides initial results on the efficacy of a novel ergonomic-oriented neck support designed to mitigate and alleviate TNS MSD and focuses on the design of an adaptive neck supporter by integrating a soft actuator massager to help deliver a soothing massage. The design was carried out using simulations, prototyping, and measurements. The massager and adaptive neck supporter prototype were validated by Finite Element Analysis prior to fabrication to assess the feasibility of the design concept. After the massager prototype was fabricated, it was tested to validate the initial concept. Future work will be focused on fabricating the full-scale adaptive neck supporter prototype as well as upgrading and optimising the design concept.

Objective The mechanism underlying the benefit of nonsurgical spinal decompression (NSSD) on low back pain is unclear. This study was performed to investigate the immediate impact of NSSD on the mechanical properties and morphology of the paraspinal muscles. Methods Participants with low back pain were recruited. NSSD therapy was provided on one occasion. A myotonometer was placed perpendicularly on the skin surface over the paraspinal muscle at the level of L3/L4 to measure the mechanical muscle properties. The multifidus thickness was measured using B-mode ultrasound and defined as the distance between the transverse process and subcutaneous tissue fascia. The difference between before and after NSSD was analyzed by a paired t-test. Results Thirty participants (mean age, 20.9 ± 0.8 years; 9 male, 21 female) were recruited. No significant difference was observed in the muscle mechanical properties or morphology between before and after the intervention. Conclusions NSSD intervention did not induce immediate changes in the paraspinal muscle mechanical properties or multifidus thickness in young adults with low back pain. NSSD might produce benefits by stimulating mechanical receptors rather than inducing morphological changes or mechanical property alterations of the muscle fibers. These parameters may not be suitable outcome measures for NSSD intervention.
