Sumario: | BACKGROUND: Thigh tissue thickness has not been examined in older females living in extended care in UK as an indicator of musculoskeletal health. This study examined the feasibility of using ultrasound imaging to measure the thickness of superficial (fat) and deep layers (muscle) of the thigh in older females living in extended care. METHODS: In ten older females in extended care (aged 80–98 years, mean 88 ± 6.8; body mass: 56.5 ± 12.6 kg) images of the anterior thigh (dominant) were taken in supine using B-mode ultrasound imaging. Superficial and deep layers were measured and percentage thickness was calculated. Independent t tests compared data from those in extended care to ten sedentary females living independently (aged 80–90 years, mean 84 ± 3.6; body mass: 61.6 ± 10.0 kg). RESULTS: Thickness of the superficial layers was not significantly different between the two groups (CI −0.017 to 0.815, p = 0.059). However, those living in extended care had greater (p < 0.001) muscle thickness (mean 2.75 ± 0.48 cm) than those living independently (mean 1.83 ± 0.3 cm), which was similarly significant when normalised for body mass (extended care 0.51 ± 0.16; independent living 0.30 ± 0.06). CONCLUSIONS: These novel findings showed it is feasible to use ultrasound to measure muscles in older females in extended care and that muscle thickness was larger than in those living independently. The reason for the difference seen between groups would need to be confirmed by a larger study that also examined factors related to risk of sarcopenia and frailty, such as nutrition and physical activity levels. |
