Difference of cervical and shoulder muscle performance and its correlation with pain and body mass index in patients with chronic neck pain / 中国康复理论与实践

ObjectiveTo test the inter-tester reliability and test-retest reliability of MyotonPRO for evaluating neck and shoulder muscle performance parameters in patients with unilateral chronic neck pain, observe the difference of muscle performance between the healthy and affected sides of patients with chronic neck pain, and analyze the factors that cause the imbalance of muscle performance in patients with chronic neck pain. MethodsFrom January to June, 2023, 32 patients with unilateral chronic neck pain in Guangdong Second Traditional Chinese Medicine Hospital were selected. Two testers used the same MyotonPRO equipment to measure the muscle tone, muscle hardness and muscle elasticity on both sides of the sternocleidomastoid muscle and the upper trapezius muscle in the relaxed position. Tester 1 repeated the measurement after an interval of 30 minutes, and Tester 2 was measured within the time interval between the two measurements of Tester 1. The intraclass correlation coefficient (ICC), standard error of mean (SEM) and minimum detectable change (MDC) were calculated simultaneously. The measurement results were plotted into Bland-Altman diagram and systematic bias analysis was performed. The difference in muscle characteristics between the affected side and the healthy side was compared. At the same time, the Visual Analogue Scale (VAS) score and body mass index (BMI) of the subjects were collected for correlation analysis. ResultsExcept the sternocleidomastoid muscle elasticity of the affected side (ICC = 0.697), the inter-tester reliability of all other parameters was high to very high (ICC = 0.719 to 0.952, SEM = 0.04 to 6.53, MDC = 0.12 to 18.11). The test-retest reliability of all parameters was high (ICC = 0.883 to 0.981, SEM = 0.03 to 5.72, MDC = 0.09 to 15.84). Bland-Altman plot analysis showed that the scatter distribution was consistent. The muscle tone, muscle hardness and muscle elasticity of sternocleidomastoid muscle and upper trapezius muscle were higher on the affected side than on the healthy side (t > 2.846, P < 0.05). The asymmetry index of tension, hardness and elasticity of upper trapezius muscle and sternocleidomastoid muscle was significantly positively correlated with VAS score and BMI (r > 0.385, P < 0.05). ConclusionMyotonPRO has good inter-tester reliability and retest reliability in evaluating the muscle performance of both sides of patients with chronic neck pain. The muscle tone, muscle hardness and muscle elasticity of sternocleidomastoid muscle and upper trapezius muscle on the affected side were higher than on the healthy side, and the difference of muscle performance was positively correlated with pain and BMI.

Clinical efficacy analysis of "Tongluo" technique on gastrocnemius muscle hardness and muscle tone in children with spastic cerebral palsy using shear wave elastography / 国际生物医学工程杂志

Objective:To investigate the clinical effect of the "Tongluo" technique on gastrocnemius muscle hardness and muscle tone in children with spastic cerebral palsy (SCP) using shear wave elastography (SWE).Methods:Forty children with SCP who were treated at the First Affiliated Hospital of Tianjin University of Traditional Chinese Medicine from January 2020 to June 2021 were selected as the observation group and received the "Tongluo" technique intervention. At the same time, 20 normal children were selected as the control group, without any intervention. Compare the various indicators of the two groups at baseline and after 1.5 and 3 months of treatment, including Young’s modulus value of the medial gastrocnemius muscle at rest, the modified Ashworth scale (MAS) score, and the clinical spasm index (CSI) score. The changes in muscle tone and spasticity of SCP children before and after treatment were compared, and the differences in the Young’s modulus between MAS and CSI levels in SCP children as well as the correlation between MAS, CSI, and Young’s modulus were analyzed.Results:The difference in Young’s modulus values of the control group at baseline, after 1.5 and 3 months of treatment was not statistically significant (all P > 0.05). At baseline, after 1.5 and 3 months of treatment, Young’s modulus value, MAS score, and total CSI score gradually decreased in the observation group, and the differences obtained from pairwise comparisons were statistically significant (all P < 0.01). At the same intervention stage, Young’s modulus value of the observation group was higher than that of the control group, with a statistically significant difference ( P < 0.01). The MAS score results showed that Young’s modulus of the observation group increased with the increase in muscle tone, and there was a positive correlation between Young’s modulus and muscle tone ( P < 0.01), and the difference in Young’s modulus corresponding to different muscle tones was statistically significant ( P < 0.05). The CSI score results showed that the Young’s modulus of the observation group increased with the increase in spasticity degree, and there was a positive correlation between the Young’s modulus and muscle tone ( P < 0.01), and the difference in Young’s modulus corresponding to different spasticity degrees was statistically significant ( P < 0.05). Conclusions:The muscle hardness of children with SCP is higher than that of normal children. The "Tongluo" technique can effectively improve muscle hardness, reduce muscle tone, and effectively improve muscle spasticity in children with SCP. The principle may be related to adjusting the internal structure of muscles to reduce muscle hardness. The results of this study can guide clinical rehabilitation and evaluation.

Conclusions:PD has a protective effect on nocturnal respiratory events, which may be due to the increased muscle tone of upper airway.

Immediate effects of extracorporeal shock wave on muscle tone, stiffness, and elasticity of wrist flexor in stroke patients / 中国组织工程研究

BACKGROUND: Studies have shown that the elasticity of the radial wrist flexor and ulnar wrist flexor muscles is related to the power of gripping, and the tension and stiffness directly affect the pinching force on the thumb side and the palm gripping ability. Extracorporeal shock waves have a definite effect on alleviating post-stroke limb spasm. OBJECTIVE: To observe the immediate effect of extracorporeal shock wave therapy on muscle tone, stiffness, and elasticity of flexor carpi radialis and flexor carpi ulnaris in stroke patients. METHODS: Twenty stroke patients with hemiplegia who met the inclusion criteria were given a single session of extracorporeal shock wave therapy on flexor carpi radialis and flexor carpi ulnaris. The oscillation frequency, logarithmic decrement, dynamic stiffness of flexor carpi radialis and flexor carpi ulnaris were detected using a muscle tone measurement device Myoton-3 before treatment and 5 minutes after treatment. At the same time, the Modified Tardieu Scale was used to evaluate spasticity of wrist flexor before and after treatment. The study protocol was implemented in accordance with the relevant ethical requirements of the First Affiliated Hospital of Guangdong Pharmaceutical University, and the enrolled patients and their families were fully informed of the whole trial. RESULTS AND CONCLUSION: After treatment, the oscillation frequency, logarithmic decrement, dynamic stiffness, and quality of muscle response of flexor carpi radialis and flexor carpi ulnaris were significantly reduced in all the patients (P < 0.01). The maximum passive range of motion of wrist extension and angle of catch following a fast velocity stretch wrist flexor were significantly higher than those before (P < 0.01). In conclusion, a single session of extracorporeal shock wave therapy can effectively reduce muscle tone and stiffness, and improve elasticity of flexor carpi radialis and flexor carpi ulnaris in stroke patients. And it can also improve the maximum passive range of motion of wrist extension.

Effect Of Magnesium On Neonates Of Mother Given Mgso4 For Pih

Preeclampsia is a hypertensive, multi-system disorder of pregnancy that significantly contributes to maternal and fetal/neonatal morbidity and mortality. It is found that Mgnesium sulfate injection is associated with lower apgar score and poor muscle tone. There are some confounding factors as meconium stained, birth asphyxia . Thus to ascertain whether poor muscle tone and poor APGAR score is solely due to Magnesium or other reasons, we have done the study

Immediate Effect of Sustained Stretching Exercises with Far Infrared on the Ankle Range of Motion and Muscle Tone in Patients with Stroke

PURPOSE: The spasticity of stroke patients decreases the ankle range of motion and increases the gastrocnemius muscle tone. This study examined the effects of stretching exercise and far infrared irradiation on the ankle function in stroke patients with spasticity. METHODS: This study was conducted on 20 stroke patients admitted to Jesaeng General Hospital, who were divided into a study group (stretching exercise with far infrared) and control group (stretching exercise only). The dorsiflexion range of motion was measured using a smartphone and the medial gastrocnemius muscle tone and stiffness were measured using a Myoton pro. RESULTS: With the exception of the non-paretic gastrocnemius muscle tone in the control group, the medial gastrocnemius muscle tone and stiffness decreased significantly in both groups. In both groups, the dorsiflexion range of motion increased significantly. In addition, the experimental group had a significantly higher dorsiflexion range of motion than the control group. On the other hand, there was no significant difference between the two groups in terms of the medial gastrocnemius muscle tone and stiffness. CONCLUSION: For stroke patients with spasticity, stretching exercises increased the ankle's range of motion and decreased the gastrocnemius muscle tone. The addition of heat therapy further increased the ankle's range of motion. On the other hand, as the sample size was small, future studies should include more subjects.

Etiological Classification and Developmental Outcomes in Floppy Infants: A Single Tertiary Center Experience / 대한소아신경학회지

PURPOSE: Floppy infants or congenital hypotonia indicates decreased muscle tone in infants secondary to abnormalities of the central or the peripheral nervous system, or both. Previous literature classified its causes as those attributable to a central vs. peripheral origin; however, recent studies have introduced a newer classification describing a combined origin. We invenstigated floppy infants by applying the new etiological classification and reviewed the most common etiologies based on the age of presentation. We additionally reviewed the clinical characteristics, diagnoses, and the developmental outcomes in these infants. METHODS: We retrospectively reviewed the electronic medical charts and recruited 116 infants diagnosed with floppy infant syndrome between January 2005 and December 2016 at Severance Children's Hospital. Among these infants, 66 with a confirmed diagnosis were reviewed for the etiological classification. Information regarding developmental outcomes was obtained via phone interviews with the infants' families. RESULTS: Based on the new etiological classification, among 69 infants with a confirmed diagnosis, in 40 (34.5%) this syndrome was of central origin, in 19 (16.4%) of peripheral origin, and in 10 (8.6%) of combined origin. Prader-Willi syndrome, myotonic dystrophy, and spinal muscular atrophy were the most common disorders observed and combined hypotonia showed the poorest developmental outcome. CONCLUSION: The study states the importance of proper evaluation of etiological diagnosis and optimal intervention for developmental prognosis. The introduction of a new etiological group of combined hypotonia especially emphasizes regular monitoring and timely rehabilitative intervention in patients for the better quality of life in them as well as their caregivers.

End-stage Treatment of a Patient with Progressive Supranuclear Palsy and Severe Retroflexion of the Neck -Improvement in Retroflexion of the Neck by Botulinum Therapy: A Case Report- / 日本プライマリ・ケア連合学会誌

Progressive supranuclear palsy (PSP) comprises psychiatric, neurological and physical complications. In the late stage, most patients with PSP are bed-bound because of motor disability. PSP manifests as predominantly axial abnormality in posture and abnormal muscle tone, resulting in cervical retroflexion and somatic pains. Severe retroflexion of the neck is frequently a cause of repeated aspiration pneumonia that affects survival expectancy. We injected botulinum toxin (BTX) for severe retroflexion using a CT-guided procedure to confirm the anatomical locations of paravertebral muscles and to localize the paravertebral target muscles for a patient with PSP who had repeated pneumonia caused by retroflexion-related dysphagia. BTX injection treatment markedly ameliorated the cervical dystonia and concomitant dysphagia. The patient has recovered and may be able to be discharged to home. There are few reports on the BTX injection technique, but BTX has analgesic effects and induces relaxation of abnormal muscle tension. Therefore, it may be applicable to other movement disorders at the late stage.

Correlation between tongue pressure and electrical activity of the suprahyoid muscles / Correlação entre pressão de língua e atividade elétrica da musculatura supra-hióidea

ABSTRACT Objective: to investigate the correlation between the tongue pressure and the electrical activity of the suprahyoid muscles. Methods: a across-sectional, observational and analytical study conducted with 15 men and 22 women. Each participant underwent simultaneous assessment of maximal tongue pressure through the Iowa Oral Performance Instrument (IOPI) and the surface electromyography of the suprahyoid muscles. They were asked to press the tongue against the hard palate in the anterior and posterior region, with and without IOPI. The adopted significance level of the performed analyses was 5%. Results: there was a moderate and significant correlation only between suprahyoid electrical activity and tongue pressure in the posterior region. It was verified that the measured electrical potentials, when using the IOPI, were greater in the tasks of anterior pressure than in the tasks of the posterior one, bilaterally. Without using the IOPI, the electrical potentials were greater in the posterior pressure than in the anterior one, bilaterally. Finally, the values of lingual pressure were compared with the bulb positioned in the anterior and posterior parts, and the anterior tongue pressure was higher. Conclusion: there was a moderate correlation between tongue pressure and electrical potential of the suprahyoid muscles, researched by the surface electromyography, only when performing activities with the posterior portion of the tongue.
