[PMID: 38998789 PMCID: PMC11241410 DOI: 10.3390/healthcare12131254] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2024] [Revised: 06/18/2024] [Accepted: 06/19/2024] [Indexed: 07/14/2024] Open
Abstract
The measurement of musculoskeletal tissue properties and loading patterns during physical activity is important for understanding the adaptation mechanisms of tissues such as bone, tendon, and muscle tissues, particularly with injury and repair. Although the properties and loading of these connective tissues have been quantified using direct measurement techniques, these methods are highly invasive and often prevent or interfere with normal activity patterns. Indirect biomechanical methods, such as estimates based on electromyography, ultrasound, and inverse dynamics, are used more widely but are known to yield different parameter values than direct measurements. Through a series of literature searches of electronic databases, including Pubmed, Embase, Web of Science, and IEEE Explore, this paper reviews current methods used for the in vivo measurement of human musculoskeletal tissue and describes the operating principals, application, and emerging research findings gained from the use of quantitative transmission-mode ultrasound measurement techniques to non-invasively characterize human bone, tendon, and muscle properties at rest and during activities of daily living. In contrast to standard ultrasound imaging approaches, these techniques assess the interaction between ultrasound compression waves and connective tissues to provide quantifiable parameters associated with the structure, instantaneous elastic modulus, and density of tissues. By taking advantage of the physical relationship between the axial velocity of ultrasound compression waves and the instantaneous modulus of the propagation material, these techniques can also be used to estimate the in vivo loading environment of relatively superficial soft connective tissues during sports and activities of daily living. This paper highlights key findings from clinical studies in which quantitative transmission-mode ultrasound has been used to measure the properties and loading of bone, tendon, and muscle tissue during common physical activities in healthy and pathological populations.

Abstract
The fragility fracture discriminative ability of radius quantitative ultrasound (QUS) was evaluated in a systematic review of 13 studies, including 16,681 individuals and 1296 fractures. The radial speed of sound (SOS) per standard deviation (SD) decrease contributed to an increased risk of total and hip fracture by 32% and 66% in women. Osteoporotic fracture, as a devastating consequence of osteoporosis, brings severe socio-economic burden. The availability of dual-energy X-ray absorptiometry (DXA), as the gold standard of diagnosis, was quite limited in remote areas. Radius QUS measured by SOS shows potential in fracture discriminative ability where DXA equipment is not available. This study aimed to provide a comprehensive evaluation of the association between radius QUS and fracture risk. A detailed article search was carried out on PubMed, EMBASE, Cochrane Libraries, CNKI, Wan-Fang database, VIP, and SinoMed for studies published between January 1980 and February 2020. We determined the estimated relative risk (RR) for fracture per each radial SOS SD decrease. A meta-analysis of studies was performed under the random-effects model. A total of 16,681 individuals were included in this review. Among the participants, 5892 were male and 10,789 were female. A total of 1296 cases of fragility fracture were included. With each SD decrease in radial SOS, the risk of overall fragility fracture and hip fracture was increased by 21% and 55%, respectively. Particularly, the risk was increased by 32% and 66% for women. The association was even stronger for postmenopausal women. Radius QUS showed great potential as an effective tool for fracture risk evaluation, especially for women.

Abstract
Introduction:
Observation is the treatment of choice for idiopathic scoliosis with Cobb angles between 15 degrees - 20 degrees in growing children. This passive approach does not address the anxiety of the patient and the stress of the parents. In this paper, we attempt to identify skeletally immature patients with mild scoliosis curvatures that are more at risk of progression and propose possible intervention for this group of subjects.
Methods:
The literature was searched in Pubmed, and additional references were searched manually in the literature.
Results:
Many studies have shown that low serum 25[OH]D level, bone mineral density (BMD), and body mass index (BMI) are related to the curve severity or progression of the curve.
We suggest that skeletally immature patients (< Risser 2) with mild curves be divided into two groups, viz. Group O (observation) with a lower risk of progression, and Group I (intervention) with a higher risk of curvature progression. We propose early intervention for the latter group.
It is suggested that pre-menarcheal, skeletally immature patients with mild idiopathic scoliosis, and low vitamin D, BMD, and BMI should be treated. Also, asymmetric foot biomechanics should be addressed, although nutrition and foot orthoses are regarded to have no role in the management of idiopathic scoliosis. The outcome of early intervention may be utterly different from late treatment when the curvature becomes more structural, and the patient more skeletally mature.
Conclusion:
Research is required to prove if the intervention is clinically indicated.

[PMID: 31735596 DOI: 10.1016/j.jocd.2019.10.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/06/2019] [Revised: 10/02/2019] [Accepted: 10/03/2019] [Indexed: 11/26/2022]
Abstract
INTRODUCTION Five-year changes in multisite quantitative ultrasound-assessed speed of sound (SOS in m/s) were studied in a cohort of women and men. The impacts of antiresorptive therapies and menopausal status on SOS were also assessed. METHODOLOGY Two SOS assessments, clinical assessments, and comprehensive questionnaires were completed 5 years apart on 509 women and 211 men. Age at first assessment was grouped into: <40 yr, 40-49 yr, 50-59 yr, 60-69 yr, 70-79 yr and 80+ yr. Mean rate of change in SOS at the distal radius and tibia were calculated for each age grouping by sex. SOS changes were stratified by antiresorptive use (yes, no) or menopausal status (premenopausal, postmenopausal, or bilateral oophorectomy). RESULTS Mean losses in SOS occurred over the 5 years in almost all age groupings. In women, mean losses in SOS for the <40 yr, 40-49 yr, 50-59 yr, 60-69 yr, 70-79 yr, and 80+ yr age groupings were -59, -83, -107, -92, -80 and -66 (p = 0.30; differences among age groupings) at the radius and -18, -16, -54, -1, -9 and 31 at the tibia (p < 0.05), respectively. In men, mean SOS losses were -101, -56, -69, -67, -83 and -127 at the radius (p = 0.61) and -46, -61, 0, -35, -29, and -26 at the tibia (p = 0.23). At the tibia, women prescribed antiresorptives had a mean increase in SOS (8.6 m/s) whereas untreated participants had a mean loss (-23.0; p < 0.001); there was no significant impact at the distal radius. There were no significant differences in change in SOS among menopausal groups (p > 0.26). CONCLUSIONS Mean SOS generally declined over 5 years in all age groupings of both sexes. The consistent mean losses in SOS over the age spans investigated are coincident with increasing fracture risk. Women on antiresorptive therapy had increased mean SOS over the 5-year assessment period at the tibia, whereas untreated women had mean losses in SOS.

Bone Rep 2020; 12:100235. [PMID: 31890757 PMCID: PMC6933268 DOI: 10.1016/j.bonr.2019.100235] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2019] [Revised: 12/04/2019] [Accepted: 12/05/2019] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND Various studies, mostly with animals, have provided evidence of adverse impacts of fluoride (F-) on bone density, collagen and microstructure, yet its effects on overall bone quality (strength) has not been clearly or extensively characterized in human populations. OBJECTIVE In this observational study, we assessed variation in an integrated measures of bone quality in a population exposed to wide-ranging F- levels (0.3 to 15.5 mg/L) in drinking water, using a novel application of non-ionizing ultrasonic method. METHOD We collected 871 speed of sound (SOS) measurements from 341 subjects residing in 25 communities, aged 10-70 years (188 males and 153 females). All subjects received scans of the cortical radius and tibia, and adults over the age of 19 received an additional scan of the phalanx. Associations between F- in drinking water and 24-h urine samples, and SOS as a measure of bone quality, were evaluated in bivariate and multivariable regressions adjusting for age, sex, BMI, smoking, and toothpaste use. RESULTS We found negative associations between F- exposure and bone quality at all three bones. Adult tibial SOS showed the strongest inverse association with F- exposure, which accounted for 20% of the variance in SOS measures (r = 0.45; n = 199; p < 0.0001). In adjusted analysis, a 1 mg/L increase in F- in drinking water was related to a reduction of 15.8 m/s (95% CI: -21.3 to -10.3), whereas a 1 mg/L increase in 24-h urinary F- (range: 0.04-39.5 mg/L) was linked to a reduction of 8.4 m/s (95% CI: -12.7, -4.12) of adult tibial SOS. Among adolescents, in contrast, weaker and non-significant inverse associations between F- exposure and SOS were found, while age, gender, and BMI were more significant predictors than in adults. CONCLUSIONS These results are indicative of a fluoride-induced deterioration of bone quality in humans, likely reflecting a combination of factors related to SOS: net bone loss, abnormal mineralization and collagen formation, or altered microarchitecture. The portable and low-cost ultrasound technique appears potentially useful for assessment of bone quality, and should be tested in other locations and for other bone-related disorders, to assess the feasibility of its more extensive diagnostic use in hard-to-reach rural regions.

The ability of calcaneal and multisite quantitative ultrasound variables in the identification of osteoporosis in women and men. Turk J Phys Med Rehabil 2019; 65:203-215. [PMID: 31663068 DOI: 10.5606/tftrd.2019.1894] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2017] [Accepted: 12/10/2018] [Indexed: 11/21/2022] Open
Abstract
Objectives The aim of this study was to assess the ability of calcaneal and multisite quantitative ultrasound (QUS) parameters in the identification of osteoporosis in women and men. Patients and methods A total of 131 women (mean age 53.7±11.9 years; range, 21 to 79 years) and 109 men (mean age 57.8±13.7 years; range, 24 to 85 years) whose bone mineral density (BMD) at the spine and proximal femur was measured between January 2010 and January 2012, using dual-energy X-ray absorptiometry (DXA) were included. Acoustic bone properties were also examined using both a calcaneal and a multisite QUS. The receiver operating characteristic analysis with the calculation of areas under the curve (AUCs) to evaluate the ability of both QUS devices for the identification of osteoporosis. We also calculated a lower and an upper threshold at a specificity of 90% and at a sensitivity of 90%, respectively, for the identification of osteoporosis along with a threshold/cut-off value with the best compromise between sensitivity and specificity. Results All calcaneal QUS parameters showed significant AUCs within the range of 0.712 (for Broadband Ultrasound Attenuation [BUA]) and 0.764 (for Speed of Sound [SOS]) in women and ranging from 0.661 (for BUA) to 0.735 (for SOS) in men, while only radial SOS of the multisite QUS demonstrated a significant AUC value of 0.661 for identifying osteoporosis in women. A Quantitative Ultrasound Index T-score of -1.53 for women and -1.68 for men showed sensitivity and specificities around 70%. Conclusion Based on the results of this study, all calcaneal QUS parameters in both women and men and possibly radial SOS measurements of the multisite QUS in women may be helpful for the identification of osteoporosis.

Abstract
It is of clinical importance to identify bone disease related to cystic fibrosis (CF) early in its course to allow therapeutic interventions that optimize bone health. To test the technical (precision) and clinical (percentage of abnormal results, correlation with clinical parameters) performance of a commercial quantitative ultrasound apparatus for radial measurements, speed of sound (SOS) was measured at the distal third of the left radius with the Omnisense 7000p apparatus (Sunlight Medical, Tel-Aviv, Israel) in a group of young adult CF patients with regular follow-up at the Brussels and Ghent University Hospital. Sixty-three (37 males) CF patients at a median (range) age of 23.5 y (18.1-39.9) were included. SOS, SOS z-score and SOS t-score were respectively 4017 ± 97 m/s, -0.31 ± 0.74 and -0.60 ± 0.78 in males and 4086 ± 97 m/s, -0.19 ± 0.75 and -0.51 ± 0.95 in females. Mean SOS t-score was significantly lower compared with the manufacturer's reference data for males (p < 0.0001) and females (p = 0.01). SOS z- and t-scores correlated with weight z-score and body mass index z-score in females. No significant correlation was found between SOS and forced expiratory volume in 1 s (%). Neither diabetes mellitus nor liver disease was found to influence SOS. Radial quantitative ultrasound has a precision of 0.55%. The SOS is in the low normal range in 14% of CF patients and is influenced by weight in female patients, but not by the severity of the lung disease.

Abstract
Multisite quantitative ultrasound (mQUS) machines are attractive tools for assessing fragility fracture risk as they are often portable, comparatively inexpensive, require little training for their use, and emit no ionizing radiation. The primary objective of this investigation was to generate an mQUS normative database of speed of sound (SOS, in m/s) measures from a large sample of randomly selected community-based individuals. mQUS (BeamMed Omnisense MultiSite Quantitative Ultrasound 7000 S) measurements were obtained and assessed at the distal radius, tibia, and phalanx. All analyses were made separately for men and women and for each anatomical site. Scatterplots (SOS vs age) identified 30-39 yr of age as periods of both maximal SOS and of relative stability for all 3 sites over the age span investigated (30-96 yr of age; 2948 women and 1176 men) and, thus, was used as the "reference" population. For cross-sectional comparison of trends over aging, a number of age groupings were created: 30-39, 40-49, 50-59, 60-69, 70-79, and 80+ yr. In general, there were decreases in SOS over increasing age groupings. The normative data generated can be used to compare a given patient's mQUS measurement with reference to a young, healthy population, assigning them a gender-appropriate T-score.

Abstract
This study assessed the ability of multisite quantitative ultrasound (mQUS) to predict fracture over a 5-year follow-up. Participants were a subset of the Canadian Multicentre Osteoporosis Study. mQUS-assessed speed of sound (SOS in m/s) at three sites (distal radius, tibia, and phalanx) and extensive questionnaires were completed, after which participants were followed for 5 years and incident fractures recorded. Two survival analyses were completed for each site--a univariate analysis and an adjusted multivariate analysis controlling for age, antiresorptive use, femoral neck bone mineral density, number of diseases, previous fractures, body mass index (BMI), parental history of hip fracture, current smoking, current alcoholic drinks >3 per day, current use of glucocorticoids, and rheumatoid arthritis diagnosis (variables from the FRAX 10-year fracture risk assessment tool). The unit of change for regression analyses was one standard deviation for all measurement sites, specific to site and sex. Separate analyses were completed for all clinical fractures, nonvertebral fractures, and hip fractures by sex. There were 2633 women and 1108 men included, and they experienced 204 incident fractures over 5 years (5.5% fractured). Univariate models revealed statistically significant (p < 0.05) predictive ability of mQUS for all three measurement sites for women alone for all three fracture types (one standard deviation decrease in SOS was associated with a 52% to 130% increase in the risk of fracture), but not for the men's group. The adjusted model found that measures at the distal radius and tibia in the women's group could significantly (p < 0.05) predict all clinical fractures and nonvertebral fractures within the next 5 years (one standard deviation decrease in SOS was associated with a 25% to 31% increase in the risk of fracture). mQUS provided significant 5-year clinical fracture prediction in women, independent of bone mineral density and other significant risk factors for fracture, when measured at the distal radius and tibia sites.

Abstract
BACKGROUND Bronchiectasis presents as a common sequela of several chronic pulmonary diseases. Bone mineral density (BMD) is generally decreased in children with cystic fibrosis (CF). Although children with non-CF bronchiectasis have similar risk factors for osteopenia/osteoporosis, data on BMD in this group of patients are lacking. OBJECTIVE To evaluate BMD in children with non-CF bronchiectasis. METHODS In this study, we evaluated BMD of the radius and tibia in 32 children (17 girls) with non-CF bronchiectasis and in 23 healthy controls matched for age, sex and pubertal stage by quantitative ultrasound (speed of sound). Daily calcium intake and pulmonary function tests and data about steroid use were noted. RESULTS Mean age was 12.5 +/- 4.6 years. Six children (18%) had moderate-to-severe lung disease (FEV(1) <60% predicted). All except 2 children (94%) were receiving inhaled steroids. There was no significant difference in BMD (expressed as z-score) of the radius and tibia between the patient and control groups (tibia z-scores: -0.1 +/- 0.9 vs. -0.8 +/- 0.8 and radius z-scores -1.3 +/- 1.4 vs. -1.0 +/- 0.9 in bronchiectasis patients and controls, respectively, p > 0.05). However, more children with non-CF bronchiectasis had osteopenia (z-scores between -1 and -2 SD) and osteoporosis (z-score <or=2 SD) compared to the control group (62 vs. 30%, p = 0.019). There was a significant correlation between age and radius z-scores (r = -0.365, p = 0.04). There was no correlation between BMD and severity of lung illness, calcium intake or cumulative steroid doses. CONCLUSION Osteopenia is more common in children with non-CF bronchiectasis compared to controls and the risk of osteoporosis and osteopenia increases with age.

Abstract
Metabolic bone disease of prematurity (MBDP) is a common and significant problem that often gives rise to osteopenia, fractures, osteomalacia, and osteoporosis. The purpose of our study is to establish normative data on bone status in premature and full-term infants to help future studies on MBDP. Bone status was prospectively determined as part of a multicenter study among newborns within 96 hours of life. The patients were divided into 2 groups: group 1 included those neonates 25-36 wk gestational age (premature), and group 2 neonates were born at 37-42 wk gestational age (full term). Demographic data were collected. The Omnisense 7000 Bone Sonometer (Sunlight Medical Ltd., Tel-Aviv, Israel) was used to determine the speed of sound (SOS) through the mid tibia, which reflects bone strength. A total of 235 patients were enrolled in this study. Group 1 (i.e., the premature infants) had a statistically lower age-adjusted SOS as compared with group 2 (i.e., the full-term infants) (analysis of variance; p=0.001). There was also a correlation between SOS and birth weight (r=0.3; p<001). This study represents the largest database of normative data for bone status measuring in preterm and term infants.
