[Purpose] Few studies on the transverse arch (TA) in the forefoot have been conducted. The forefoot is where pains occur most frequently and is related to walking and balance; hence, paying attention to TA is vital. However, the relationship between TA and foot muscles has not been investigated. Therefore, this study aims to investigate muscles related to TA. [Subjects and Methods] Nineteen healthy young males were included. Measurements of their feet, excluding one foot with recent foot pain (n=37), were obtained. The height of TA (TAH) was measured in two ways: during 10% and 90% loading of body weight. The cross-sectional area and thickness of five muscles were measured: flexor digitorum longus, peroneus longus and brevis, flexor hallucis brevis, flexor digitorum brevis (FDB) and abductor hallucis (ABH). All measurements were performed with an ultrasound device. [Results] FDB and ABH were correlated with TAH during 10% and 90% loading after removing the effect of body mass index and age. The greater FDB and ABH, the higher TAH. [Conclusion] As FDB becomes larger, the second, third and fourth metatarsal heads are raised more. Furthermore, the height of the first metatarsal head is lowered by a larger ABH. These mechanisms may increase TAH.

Objectives: This study aimed to examine the factors for reducing monetary loss due to presenteeism by using a tailored healthcare web-application among office workers with chronic neck pain. Methods: The study was single-arm pre-post comparison study using secondary data of 130 Japanese office workers with chronic neck pain who used a tailored healthcare web-application (web-app) over 12 weeks. This data was obtained from BackTech Inc. (Kyoto, Japan), which manages the healthcare web-app. The primary outcome measure was the monetary loss due to presenteeism based on the quality and quantity method. Secondary outcome measures were intensity of physical symptoms measured by the Visual Analog Scale, frequency of web-app use obtained from the database, and the risk of depression score assessed by the Depression and Suicide Screen. Results: Eighty-six participants were included in the complete-case analysis. Monetary loss due to presenteeism and the risk of depression reduced, while physical symptoms improved significantly (p<0.01) after using the web-app. After covariate adjustment, decrease in neck pain intensity (β=0.25, confidence interval=2.34 to 32.66) and high frequency of web-app use (β=−0.24, confidence interval=−10.29 to −0.63) were significantly associated with a reduction in monetary loss due to presenteeism. Conclusion: Neck pain intensity and frequency of web-app use may be important factors for reducing monetary loss due to presenteeism among office workers with chronic neck pain who used a tailored health care web-app.

[Purpose] Hallux valgus occurs in the forefoot where the transverse arch is located and may be a factor involved in forefoot pain. The relationship between forefoot pain and forefoot structure is unknown. This study aimed to analyze the relationship between forefoot pain and the transverse arch in patients with hallux valgus. [Participants and Methods] In this study, 122 (197 feet) adult females (46 to 86 years old) with hallux valgus were studied. By using questionnaires, the females were divided into two groups depending on whether or not they had forefoot pain (a group with forefoot pain [P group] and a group without forefoot pain [NP group]). The hallux valgus angle was measured using a goniometer, and the transverse arch was measured using a weight-bearing plantar ultrasonography imaging device. The transverse arch measurements included the transverse arch height and length. [Results] Only the transverse arch length, even after adjustment, was significantly greater in the P group. No significant difference was found between the hallux valgus angle and the transverse arch height. [Conclusion] The greater transverse arch length in the P group was possibly due to the collapsing transverse arch support muscles. Increased width probably caused inadequate impact absorption which in turn led to forefoot pain.

[Purpose] This study aimed to clarify the effects of Capacitive and Resistive electric transfer (CRet) on changes in muscle flexibility and lumbopelvic alignment after fatiguing exercise. [Subjects and Methods] Twenty-two healthy males were assigned into either the CRet (n=11) or control (n=11) group. Fatiguing exercise and CRet intervention were applied at the quadriceps muscle of the participants’ dominant legs. The Ely test, pelvic tilt, lumbar lordosis, and superficial temperature were measured before and after exercise and for 30 minutes after intervention. Statistical analysis was performed using one-way analysis of variance, with Tukey’s post-hoc multiple comparison test to clarify within-group changes and Student’s t-test to clarify between-group differences. [Results] The Ely test and pelvic tilt were significantly different in both groups after exercise, but there was no difference in the CRet group after intervention. Superficial temperature significantly increased in the CRet group for 30 minutes after intervention, in contrast to after the exercise and intervention in the control group. There was no significant between-group difference at any timepoint, except in superficial temperature. [Conclusion] CRet could effectively improve muscle flexibility and lumbopelvic alignment after fatiguing exercise.
