“…We found no significant changes in BMI percentile, percent body fat, or bone density from before to after the intervention. However, a longer duration of the intervention may be more likely to benefit both body composition and bone health (37, 38).…”

Children with cerebral palsy (CP) have motor impairments that make it challenging for them to participate in standard physical activity (PA) interventions. There is a need to evaluate adapted PA interventions for this population. Dance can promote coordination, posture, muscle strength, motor learning, and executive functioning. This pilot study evaluated the feasibility and the effects of a new therapeutic ballet intervention specifically designed for children with CP. Methods: Eight children with CP (9–14 y/o; 75% female) participated in a 6-week therapeutic ballet intervention. Outcomes were measured in multiple domains, including body composition (DXA), muscle strength (hand-grip dynamometer), habitual physical activity, gait and selective motor control functions, and executive functioning. Follow-up assessments of habitual physical activity, gait, and executive functioning were completed 4 to 5 weeks post-intervention. Results: Five of the eight participants were overfat or obese based on DXA percentage of body fat. All participants were below the 50th percentile for their age and gender for bone density. Four participants showed a trend to improve hand-grip strength in one hand only, while one improved in both hands. There were significant improvements in gait across time points (pre, post, and follow-up), specifically in time of ambulation ( X pre = 4.36, X post = 4.22, X follow−up = 3.72, d = 0.056, p = 0.02), and in step length (cm) on the right: X pre = 48.29, X post = 50.77, X follow−up = 52.11, d = 0.22, p = 0.027, and left stride: X pre = 96.29, X post = 102.20, X follow−up = 104.20, d = 0.30, p = 0.027, indicating gait changes in bilateral lower extremities. There was improvement in inhibitory control ( d = 0.78; 95% Confidence Limit = ±0.71, p < 0.05) with large individual responses primarily among those above the mean at baseline. Conclusions: Therapeutic ballet may prove to be a useful intervention to promote physiological and cognitive functions in children with CP. Results demonstrated feasibility of the physical, physiological, and cognitive assessments and suggested improvements in participants' gait and inhibitory control with large individual responses. Modifications to personalize the intervention may be needed to optimize positive outcomes. Clinical Trial Registration: www.ClinicalTrials.gov , identifier: NCT03681171

“…Recently, another method for non-invasive bone structure assessment using DXA images called 3D-SHAPER was developed (21). 3D-SHAPER modeling provides a detailed proximal femur analysis including separate assessment of the cortical layer and trabecular macrostructure, which could potentially improve identification of those at elevated fracture risk (21,22,23,24). This methodology has not been evaluated in patients with acromegaly.…”

Introduction Impaired bone microarchitecture is involved in vertebral fracture (VF) development among acromegaly patients. Aim of the study Comparison of DXA-derived bone parameters, areal BMD (aBMD), trabecular bone score (TBS) and 3D-SHAPER parameters in acromegaly patients with healthy controls. Methods This cross-sectional study evaluated acromegaly patients and a control group of healthy subjects. In all subjects, a single measurement of pituitary axis hormone levels, bone turnover markers, aBMD, (total hip (TH) and lumbar spine (LS)), TBS and 3D-SHAPER of the proximal femur region was performed. All subjects underwent DXA assessment of VF using the semiquantitative approach. Results One hundred six patients with acromegaly (mean age 56.6 years, BMI 30.2 kg/m2) and 104 control subjects (mean age 54.06 years, 28.4 BMI kg/m2) were included. After adjustment for weight, LS aBMD, TBS and TH trabecular volumetric BMD (vBMD) remained lower (P = 0.0048, <0.0001 and <0.0001, respectively) while cortical thickness (Cth) at TH and neck remained thicker (P = 0.006) in acromegaly patients compared with controls. The best multivariate model (model 1) discriminating patients with and without acromegaly included TBS, TH trabecular vBMD and TH Cth parameters (all P < 0.05). Twenty-two VFs (13 acromegaly subjects) were recognized. In these subjects after adjustment for age, FN aBMD, TH cortical sBMD and TH cortical vBMD remained significantly associated with the prevalent VF (OR = 2.69 (1.07–6.78), 2.84 (1.24–6.51) and 2.38 (1.11–5.10) for neck aBMD, TH cortical sBMD and TH cortical vBMD respectively)). The AUCs were similar for each parameter in this model. Conclusions Acromegaly patients, regardless of VF presence, have lower trabecular bone quantitative parameters, but those with VFs had decreased cortical density.

“…Regarding this subject, a recent study performed in our laboratory in artistic swimmers has shown the importance of considering a complementary workout out of the water to improve femoral neck aBMD [30]. Moreover, a research performed on professional ballet dancers using 3D-DXA modelling revealed significantly higher aBMD, trabecular and cortical vBMD and cortical thickness compared to sedentary controls [31]. Artistic swimmers perform similar movements and have analogous aesthetic characteristics as ballet dancers except for the weight-bearing forces generated by the impacts with the floor, which could explain the higher bone density values found in ballet dancers.…”

Cortical and trabecular volumetric bone mineral density (vBMD), cortical thickness and surface BMD (sBMD, density-to-thickness ratio) were analysed in the proximal femur of elite female football players and artistic swimmers using a three-dimensional dual-energy X-ray absorptiometry (3D-DXA) new software, and compared to sedentary controls. Football players had significantly higher (p<0.05) vBMD (mg/cm3) in trabecular (263±44) and cortical femur (886±69) than artistic swimmers (224±43 and 844±89) and sedentary controls (215±51 and 841±85). Football players had also higher (p<0.05) cortical thickness (2.12±0.19 mm) and sBMD (188±22 mg/cm2) compared to artistic swimmers (1.85±0.15 and 156±21) and sedentary controls (1.87±0.16 and 158±23). Artistic swimmers did not show significant differences in any parameter analysed for 3D-DXA when compared to sedentary controls. The 3D-DXA modelling revealed statistical differences in cortical thickness and vBMD between female athletes engaged in weight-bearing (football) and non-weight bearing (swimming) sports and did not show differences between the non-weight bearing sport and the sedentary controls. 3D-DXA modelling could provide insight into bone remodelling in sports field, allowing to evaluate femoral trabecular and cortical strength from standard DXA scans.
