“…An earlier USE study reported increased mean gastrocnemius and masseter muscle stiffness in men compared to women but found no significant difference (Arda et al 2011). A recent study (Saeki et al 2019) using torque-angle curves to assess muscle stiffness found higher soleus stiffness in young women compared to men but no significant difference in gastrocnemius stiffness. These discrepant studies suggest that gender differences may be dependent on the muscle studied and the technique employed to do so.…”

Determining the effect of ageing on thigh muscle stiffness using magnetic resonance elastography (MRE) and investigate whether fat fraction and muscle cross-sectional area (CSA) are related to stiffness. Six healthy older adults in their eighth and ninth decade and eight healthy young men were recruited and underwent a 3 T MRI protocol including MRE and Dixon fat fraction imaging. Muscle stiffness, fat fraction and muscle CSA were calculated in ROIs corresponding to the four quadriceps muscles (i.e. vastus lateralis (VL), vastus medialis (VM), vastus intermedius (VI), rectus femoris (RF)), combined quadriceps, combined hamstrings and adductors and whole thigh. Muscle stiffness was significantly reduced (p < 0.05) in the older group in all measured ROIs except the VI (p = 0.573) and RF (p = 0.081). Similarly, mean fat fraction was significantly increased

“…These analyses were adjusted statistically for sex (categorical variable), age and BMI (continuous variables) by including them in the general linear model as covariates. The adjustments were determined beforehand since muscles alter with age (24), and muscle stiffness has been shown to be affected by sex (25,26) and BMI (13). Pairwise comparison was conducted with least significant difference.…”

Increased neck muscle stiffness in migraine patients with ictal neck pain: A shear wave elastography study

Background Ictal neck pain is a frequent symptom reported by half of migraine patients. It is unknown if neck pain is caused by peripheral or central mechanisms. Neck muscle stiffness can be investigated with ultrasound shear wave elastography. Objectives To determine if migraine patients with ictal neck pain have stiffer neck muscles interictally compared with patients without ictal neck pain and controls. Methods This was a cross-sectional study investigating neck muscle stiffness, pressure pain thresholds and neck pain symptoms in 100 migraine patients recruited from a tertiary headache center and 46 controls. Results Patients with ictal neck pain had increased mean neck muscle stiffness interictally compared to both migraine patients without ictal neck pain ( p = 0.018) and controls ( p = 0.036). Muscle stiffness was negatively correlated with pressure pain thresholds in the neck in migraine patients with ictal neck pain (r = −0.292, p = 0.042). There were no differences in mean pressure pain thresholds between migraine subgroups. Conclusions Migraine patients with ictal neck pain have stiffer neck muscles interictally compared with migraine patients without ictal neck pain and controls measured with ultrasound shear wave elastography. The increased stiffness could be due to local alterations in the neck muscles. Trial registration: clinical-trials.gov, identifier: NCT03626805

“…There are some studies which investigated the menstrual cycle effect on tissue stiffness, but they predominantly focused on the muscle stiffness. Saeki et al (14) investigated the menstrual cycle effect on the triceps surae muscle by shear-wave elastography. Similar to our results, they reported that menstrual cycle did not affect the stiffness of the triceps surae muscle.…”

“…Similar to previous studies (14,17), the menstrual cycle was classified into 3 phases; follicular, ovulatory, and luteal phases (1-9 days, 10-14 days, and 15-28 days from the first day of menses, respectively). Mechanical properties of selected muscle and tendons were measured in the central days of the 3 phases.…”

“…Indeed, there are some attempt which investigated the effect of menstrual cycle on mechanical properties of muscle and/or tendon, but the results of these studies are contradicting. Some of these studies revealed a decrease in muscle stiffness and/ Menstrual cycle effect on muscle and tendon or elasticity in ovulation phase (11,12); however, the other reported no significant difference in muscle stiffness and/ or elasticity among the menstrual phases (13,14). Furthermore, there are limited study about menstrual cycle effect on tendon mechanical properties, and they used indirect methods to determine the differences in tendon mechanical properties (15,16).…”

Background. The evidences suggest that the risk of orthopaedic injury is the highest in the ovulation phase of the menstrual cycle. The change on mechanical properties of muscle and/or tendon related the higher estrogen concentration in the ovulation phase may be related to the highest risk of orthopaedic injury in ovulation phase. The purpose of the study was to investigate the menstrual cycle effect on the stiffness, elasticity and/or tone of the medial gastrocnemius muscle, Achilles and patellar tendons. Methods. The study was carried out in 30 healthy sedentary young females. The stiffness, elasticity and/or tone of the medial gastrocnemius muscle, Achilles and patellar tendons were measured using a MyotonPRO device. The stiffness, elasticity and/or tone of selected muscle and tendons were measured in the follicular, ovulatory, and luteal phases to determine the menstrual cycle variation. Results. There was no significant difference in stiffness, elasticity and tone of the Achilles tendon, patellar tendon and medial gastrocnemius muscle among phases (p > .05). Conclusions. The results suggest that the menstrual cycle do not affect the stiffness, elasticity and/or tone of the medial gastrocnemius muscle, Achilles and patellar tendons.
