“…However, this study found no significant differences in the factors related to posture and physical activity, suggesting that differences in muscle hardness are not related to posture or physical activity. A previous study reported that the muscle hardness of the trapezius muscle is associated with blood flow velocity [38]. In addition to physical factors such as posture measured in this study, blood flow may have been related to muscle hardness.…”

Background and Objectives: Understanding the relationships between subjective shoulder stiffness, muscle hardness, and various factors is crucial. Our cross-sectional study identified subgroups of shoulder stiffness based on symptoms and muscle hardness and investigated associated factors. Materials and Methods: measures included subjective stiffness, pain, muscle hardness, and factors like physical and psychological conditions, pressure pain threshold, postural alignment, heart rate variability, and electroencephalography in 40 healthy young individuals. Results: Three clusters were identified: Cluster 1 with high stiffness, pain, and muscle hardness; Cluster 2 with low stiffness and pain but high muscle hardness; and Cluster 3 with low levels of all factors. Cluster 1 had significantly higher central sensitization-related symptoms (CSS) scores than Cluster 2. Subjective stiffness is positively correlated with psychological factors. Conclusions: our results suggest that CSS impacts subjective symptom severity among individuals with similar shoulder muscle hardness.

“…Muscle hardness was quantitatively evaluated by a trained examiner using a portable muscle hardness meter (NEUTONE TDM-Z2; TRY-ALL Corp., Chiba, Japan). A similar device was used in previous studies [ 22 – 24 ]. Our previous study showed that the muscle hardness meter had excellent intratester reliability for the trapezius muscle ( ICC 1,5 = 0.992–0.995) [ 25 ].…”

Background Local alternating heat and cold stimulation as an alternative to contrast bath may cause intermittent vasoconstriction and vasodilation, inducing a vascular pumping effect and consequently promoting increased tissue blood flow and oxygenation. This study aimed to examine the effects of local alternating heat and cold stimulation, using a wearable thermal device, on the hemodynamics of fatigued muscle tissue and autonomic nervous activity. Methods Twenty healthy individuals experienced fatigue in the periarticular muscles of the shoulder joint due to a typing task. Local alternating heat and cold stimulations were then applied to the upper trapezius muscle. Muscle hardness was measured using a muscle hardness meter, and muscle tissue hemodynamics and oxygenation were evaluated using near-infrared spectroscopy before and after the stimulation. Autonomic nervous activity was also evaluated using heart rate variability. Results Alternating heat and cold stimulation decreased muscle hardness of the fatigued trapezius muscle from 1.38 ± 0.15 to 1.31 ± 0.14 N (P < 0.01). The concentration of total hemoglobin in the trapezius muscle tissue increased from − 0.21 ± 1.36 to 2.29 ± 3.42 µmol/l (P < 0.01), and the tissue hemoglobin oxygen saturation also increased from 70.1 ± 5.4 to 71.1 ± 6.0% (P < 0.05). Additionally, the heart rate variability parameter, which is an index of sympathetic nervous activity, increased from 3.82 ± 2.96 to 6.86 ± 3.49 (P < 0.01). A correlation was found between increased tissue hemoglobin oxygen saturation and increased parameters of sympathetic nervous activity (r = 0.50, P < 0.05). Conclusions Local alternating heat and cold stimulation affected the hemodynamic response in fatigued muscle tissue and autonomic nervous activity. This stimulation is more efficient than conventional contrast baths in terms of mobility and temperature control and has potential as a new versatile therapeutic intervention for muscle fatigue.

“…Another study evaluating the e cacy of muscle exercises in patients with neck pain [51] found that patients after lower trapezius strengthening exercises show signi cant improvement in muscle thickness and contraction, and these effects are positively correlated with the improvement of patients' neck pain symptoms. Many other studies [52,53] investigated the potential link between cervical muscle stiffness and neck pain. All these studies have proven the important role of cervical soft tissue in neck pain and cervical spine degeneration, as well as the stiffness of cervical soft tissue commonly associated with neck pain [54,55] .…”

Background: To evaluate the reliability the Soft Tissue Tension Cloud Chart(STTCC) technology, an original method combining multi-point Cervical Paravertebral Soft Tissue Test(CPSTT) with MATLAB software, and preliminary analyze immediate effect of Orthopaedic Manual Therapy(OMT) on Cervical Paravertebral Soft Tissue. Methods: 30 patients with Cervical Spondylotic Radiculopathy(CSR) are included in this study to analyze the difference between before and after the treatment of Cervical Rotation-Traction Manipulation(CRTM), the representative of OMT in Traditional Chinese Medicine by STTCC technology. Results: The STTCC results show that the CPSTT after CRTM in CSR patients is significantly lower than before CRTM, with a statistically significant difference(P<0.001). Meanwhile, the CPSTT of the ill side(with radicular pain or numbness) is higher than that of the healthy side(without symptoms) from the fifth to seventh cervical segment before CRTM(P<0.001), while this difference disappears after CRTM(P=0.231). Conclusions: STTCC technology is a reliable method to analyze the immediate effect of OMT. CSR patients have the characteristics of an uneven distribution of CPSTT; CRTM not only has the effect of reducing the cervical soft tissue tension of CSR patients but also can balance their uneven distribution between the ill side and the healthy side. Trial registration: This study was approved by the Chinese Clinical Trials Registry(Website: .https://www.chictr.org.cn.)on 20/04/2021 and the Registration Number is ChiCTR2100045648.
