“…28) In another study, a decrease in TMM as evaluated by ultrasonography in older patients was associated with a decrease in walking ability. 17) These findings suggest that TMM is important for restoring walking independence. However, these studies included patients with osteoporosis and older patients, not those with hip fractures.…”

“…Previous studies have investigated the relationship between loss of TMM and walking ability as evaluated by ultrasonography. 17 ) Although ultrasonography can evaluate muscle mass noninvasively, it is not yet widely used. BIA is the gold standard method of evaluating muscle mass and is widely used in clinical practice as a simple and noninvasive instrument for evaluating muscle mass.…”

“… 16 ) Another study in which the TMM was evaluated using ultrasonography in older adults reported that a decrease in TMM was associated with a decrease in walking ability. 17 ) Therefore, it is considered that TMM decreases after hip fracture and that decreased TMM is associated with decreased walking ability. These findings suggest that it is important to evaluate TMM in patients with hip fracture and that its relationship with walking ability should be clarified.…”

Objectives: This study aimed to investigate the relationship between trunk muscle mass index (TMI), appendicular skeletal muscle mass index (ASMI), and walking independence in patients aged 65 years and older undergoing rehabilitation for hip fracture. Methods: This retrospective, observational study was conducted in a convalescent rehabilitation ward and included 314 patients (aged ≥65 years) with hip fracture. The patients were classified into the independence group [functional independence measure (FIM)-walk score ≥6] or the non-independence group (FIM-walk score ≤5) according to the mobility item score among the motor FIM items at the time of discharge. Age, sex, TMI, ASMI, and Mini Nutritional Assessment-Short Form (MNA-SF) data were also extracted. Between-group and multivariate analyses were performed to evaluate the factors associated with walking independence. Results: The independence group had higher TMI (males: 6.6±0.9 vs. 5.6±1.0 kg/m 2 , P <0.001; females: 6.1±0.8 vs. 5.7±1.0 kg/m 2 , P <0.001), ASMI (males: 6.7±1.1 vs. 5.9±1.3 kg/m 2 , P=0.004; females: 5.3±0.9 vs. 4.7±0.8 kg/m 2 , P <0.001), MMSE-J (21.5±4.9 vs. 16.4±4.5 points, P <0.001), and MNA-SF [median (interquartile range): 8 (6–9) vs. 7 (5–8) points, P <0.001] than the non-independence group. Multivariate analysis showed that TMI at admission was significantly associated with walking independence (odds ratio: 1.86, 95% confidence interval: 1.28–2.72, P <0.001). Conclusions: This study suggests that a higher TMI at admission was important for acquiring walking independence in patients with hip fracture and shows the importance of early evaluation of TMI during hospitalization of patients with hip fracture.

“…Several reports have shown that in addition to the lower limb muscles, the trunk muscles are also involved in mobility in older adults. Masaki et al reported that a reduction in maximal walking speed is associated with a reduction in erector spinae muscle mass in community-dwelling older adults [11]. Lim et al reported that the erector spinae and gluteus maximus are engaged in maintaining balance during the early stance of walking in older adults [12].…”

Background Older patients with diabetes mellitus are more susceptible to frailty. Although some imaging markers of appendicular skeletal muscle mass obtained using dual-energy X-ray absorptiometry or computed tomography (CT) imaging can reflect frailty status, the association between imaging indices obtained by abdominal CT scans and frailty in older inpatients has not been reported. Methods A total of 151 older inpatients with diabetes mellitus (median age, 79 years; men, 42%) who underwent abdominal CT scans close to the admission were studied to examine the associations between abdominal CT indices and frailty. We used two frailty definitions: the modified Cardiovascular Health Study (mCHS) criteria and Kihon Checklist (KCL) criteria. Using the imaging analysis software SYNAPSE VINCENT®, we compared the areas of four truncal muscles (erector spinae, iliopsoas, rectus abdominis, and abdominal oblique muscles) and the ratio of the CT values of the liver and spleen (L/S) between frail and non-frail patients. The muscle areas that showed the strongest associations with frailty were also investigated in relation to grip strength and walking speed. Finally, we performed multivariate binominal logistic regression analysis to assess the independent associations of muscle areas and L/S with the prevalence of frailty. Results The prevalence of frailty defined by the mCHS and KCL criteria was 55% and 52%, respectively. The area of the erector spinae muscle was most significantly associated with frailty, and was significantly smaller in mCHS-defined frail patients of both sexes and in men with KCL-defined frailty. The erector spinae muscle area was also positively correlated with grip strength and walking speed. In contrast, the L/S ratio was higher in men with KCL-defined frailty. Multivariate logistic regression analyses revealed that the area of the erector spinae muscle was independently associated with mCHS-defined frailty in women, and the L/S ratio was associated with KCL-defined frailty in men. Conclusions The erector spinae muscle area and low liver fat could be indices of frailty in older patients with diabetes.
