Purpose To investigate effects of a hard and soft type foot orthoses on three-dimensional (3D) kinetic moments of ankle joints known to contribute to ankle arthrosis in individuals with HV using a force platform system based on motion analysis during gait. Study design This was a repeated-measures design. Methods Kinetic 3D moment data were obtained from 26 participants with HV. Two force platforms were used to collect kinetic data in three different foot-toe orthosis conditions during free walking. Repeated-measures analysis of variance was used to determine the effect of each foot-toe orthosis condition on ankle moment variables. Results There were significant differences in the maximal plantar flexion moment, second peak eversion moment, and maximal external rotation moment occurred at the terminal stance phase of the ankle joints between without foot orthosis and hard foot orthosis conditions ( p <0.05). In addition, there were significant differences in maximal plantar flexion moment occurred at the late stance phase during gait between without foot orthosis and soft foot orthosis conditions ( p < 0.05). Conclusions The results indicated the potential relationship between HV deformity and ankle osteoarthrosis through increasing ankle moments at the terminal stance under the without foot-toe orthosis condition. Particularly, the application of a hard foot-toe orthosis could contribute to treatment and prevention of ankle osteoarthrosis as well as HV correction.","PeriodicalId":102754,"journal":{"name":"Journal of Musculoskeletal Science and Technology","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117207358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Purpose This study aimed to determine the changes in muscle activity and ratio for the upper trapezius (UT), middle trapezius (MT), and lower trapezius (LT) muscles during the MSCRE in healthy participants without shoulder pain. Study design Cross-sectional study Methods We included participants who were 23 healthy individuals aged 23–39 years. The participants performed a pulling motion three times during the MSCRE at each of the following trunk angles: upright posture 0˚, forward lean 30˚, and backward lean 20˚. Surface electromyography was performed for the UT, MT, and LT muscles during the 5-s isometric contraction, with the participant in a preset position, while the muscle activity was normalized with the maximal voluntary isometric contraction using the manual muscle test. Results The UT and LT muscle activities showed significant differences in angle ( p <0.05); the highest muscle activity was observed for the UT at backward lean 20˚ and LT at forward lean 30˚. The UT/MT and UT/LT ratios showed significant differences in angle ( p <0.05), with the highest values observed at backward lean 20˚ for both the ratios. Conclusions These results suggest that the forward lean 30˚ trunk angle was most suitable for the MSCRE in the selective strengthening of the LT muscle, indicating that the trunk should be tilted forward during exercise for normal and balanced recovery of trapezius muscle activities in shoulder rehabilitation.","PeriodicalId":102754,"journal":{"name":"Journal of Musculoskeletal Science and Technology","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125624922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The total rotational ROM were measured using Smart KEMA motion sensor, and external to internal rotation muscle strength were measured using Smart KEMA pulling sensor. Results The results showed that there were significant differences in the total rotation ROM between the groups ( p <0.05). However, no significant difference was found in the external to internal rotation muscle strength ratio ( p >0.05). Conclusions Assembly line workers with SAPS had limited total rotational ROM. However, the ratio of external to internal rotation muscle strength ratio was not different for workers without SAPS. These characteristics can be considered factors that should be considered in evaluating workers with SAPS and establishing a treatment plan.","PeriodicalId":102754,"journal":{"name":"Journal of Musculoskeletal Science and Technology","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124501494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Purpose The purpose of the current study was to confirm the correlation between QoL of incontinence symptoms and PFM strength, hip extensor, abductor, and adductor strength in women with SUI. Methods Forty-two women with SUI were recruited for the present study. PFM performance was measured by perineometry. Hip extensor, abductor and adductor strength were measured by dynamometry. QoL of incontinence symptoms was measured by incontinence quality of life questionnaire (I-QOL). The significance of the correlations between I-QOL and hip joint muscle and PFM strength was assessed using Pearson correlation coefficients. Alpha value was set at 0.05. Results Avoidance and limiting behaviors factor in I-QOL was correlated with PFM strength ( r =0.524, p <0.05), hip adductor strength ( r =0.356, p <0.05) and hip abductor strength ( r =0.352, p <0.05) in the order.

Impairment of thoracic spine mobility is frequently reported in axial rotation and extension. Thoracic spine extension mobility (TE) is required in the end range of shoulder flexion, and is essential for ideal pattern of trunk extension. Prone trunk extension is performed to check the ideal trunk extension pattern. Park et al. reported that those with a slouched posture had smaller thoracic spine extension and greater lumbar extension during the prone trunk extension compared to those without slouched posture. Also, the muscle activity ratio between the thoracis and lumborum of erector spinae was lower in those with a slouched posture. During prone trunk extension, the thoracic extensor is decreased and the lumbar extensor is excessively activated, which is a factor inducing low back pain. Therefore, muscle activity of thoracic erector spinae was emphasized to manage and prevent low back pain. During the thoracic extension, the thoracic erector spinae such as longissimus thoracis (LT), and iliocostalis lumborum pars thoracis (ICT) are activated. However, since the erector spinae muscle of lumborum such as iliocostalis pars lumborum (ICL) can be used as compensation during trunk Comparison of Muscle Activity of the Erector Spinae according to Thoracic Spine Extension Mobility","PeriodicalId":102754,"journal":{"name":"Journal of Musculoskeletal Science and Technology","volume":"199 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128147753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
