Thigh muscle and subcutaneous tissue thickness measured using ultrasound imaging in older females living in extended care: a preliminary study

ABSTRACT Background: The evaluation of collagen in the abdominal wall has been increasingly studied because of the relevance on collagen in the healing process after laparotomy. Aim: To evaluate the amount of collagen in the linea alba of patients undergoing laparotomic bariatric surgery and comparing with non-obese cadavers. Methods: Were evaluated 88 samples of aponeurosis from abdominal linea alba of 44 obese patients (obesity group) and 44 non-obese cadavers (control group). The samples were collected in 2013 and 2104, and were sorted according to age (18-30, 31-45 and 46-60), gender, BMI, waist and cervical circumference, and subcutaneous tissue thickness. Material for biopsy was collected from the supraumbilical region of the linea alba for immunohistochemical analysis differentiating collagen type 1 and type 3 and the 1/3 ratio. Image-Pro Plus pixel counting software was used to measure the amount of collagen. Results: The obesity group evidenced mean age 44.11±9.90 years; 18-30 age group had three (6.8%) obese individuals; 31-45 had 22 (50%) and 46-60 had 19 (43.1%). Females were present in 81.8% (n=36); BMI (kg/m²) was 48.81±6.5; waist circumference (cm) was 136.761±13.55; subcutaneous tissue thickness (cm) 4.873±0.916. Considering age groups, gender and BMI, there were statistical differences in all tests when compared with the cadavers. Conclusion: The amount of collagen in the linea alba above the umbilical region in the morbidly obese patients was smaller than in the non-obese cadavers in the same age group.

Research Problem / Aim: The ventrogluteal injection area is one of the areas most frequently used by nurses in intramuscular injection applications. The thicknesses of the subcutaneous tissue and the muscle tissue in this area are important for a safe injection. The aim of this study is the determination of the subcutaneous and muscle tissue thicknesses on the ventrogluteal injection area and the anthropometric data about it. Method: The study has designed a cross-sectional study. 150 individuals who applied to the ultrasound unit of the hospital and accepted to participate in the study were included in the study. The ventrogluteal injection area was determined with the ‘’V’’ method by the researcher. The subcutaneous and muscle tissue thicknesses from the areas on the injection area and the areas 2 and 4 cm around the injection area were determined using the ultrasound device. Moreover, the relation between the anthropometric measurements of the individuals (height, weight, waist, hip and crista iliaca circumferences, distance between the large trochanter and crista iliaca and crista iliaca anterior) and the tissue thicknesses on the injection area were evaluated. The data of the research were evaluated with definitive statistics, ANOVA test and posthoc Tukey test, t test and correlation analysis. The p<0.05 value was accepted as statistically significant for all results. Findings: The average subcutaneous tissue thickness in the injection area was determined as 15.44±8.01 mm and the average tissue thickness there was determined as 31.75±11.86 mm. The subcutaneous tissue thickness in women was found more than the subcutaneous tissue thickness in men. When the tissue thicknesses 2 and 4 cm around the injection area were analyzed, it was found that the area where the total tissue thickness was the least was over 2 cm (41.67±14.83) and over 4 cm (35.79±15.55) of the injection area. It was determined that the average total thickness 4 cm around the injection area was less than 38 mm in underwight individuals. Conclusions: According to the results obtained from the study, the weight and body mass index of the individual should be considered in the choice of the injection area and the length of the needle to be used when the ventrogluteal injection area was used in intramuscular injections. Especially in obese individuals, longer needles can be preferred. Besides, it must be thought that there may be the risk of bone injury 4 cm around the injection area in asthenic individuals and individuals with normal weight. Moreover, since the individuals’ having a large waist and hip circumference is related to their subcutaneous tissue thickness, it is recommended that long needles should be chosen in these individuals.

Abstract Background: Real-time ultrasound imaging (RUSI) has been increasingly used as a form of biofeedback when instructing and re-training muscle contraction. However, the effectiveness of the RUSI on a single sustained contraction of the lumbar multifidus (LM) and transversus abdominis (TrA) has rarely been reported. This preliminary study aimed to determine if the use of RUSI, as visual biofeedback, could enhance the ability of activation and continuous contraction of the trunk muscles including LM and TrA.Methods: Forty healthy individuals were included and randomly assigned into the experimental group and control group. All subjects performed a preferential activation of the LM and/or TrA (maintained the constraction of LM and/or TrA for 30 seconds and then relaxed for two minutes), while those in the experimental group also received visual feedback provided by RUSI. The thickness of LM and/or TrA at rest and during contraction (Tc-max, T15s, and T30s) were extracted and recorded. The experiment was repeated three times.Results: No significant differences were found in the thickness of LM at rest (P > 0.999), Tc-max (P > 0.999), and T15s (P = 0.414) between the two groups. However, the ability to recruit LM muscle contraction differed between groups at T30s (P = 0.006), with subjects in the experimental group that received visual ultrasound biofeedback maintaining a relative maximum contraction. Besides, no significant differences were found in the TrA muscle thickness at rest (P > 0.999) and Tc-max (P > 0.999) between the two groups. However, significant differences of contraction thickness were found at T15s (P = 0.031) and T30s (P = 0.010) between the two groups during the Abdominal Drawing-in Maneuver (ADIM), with greater TrA muscle contraction thickness in the experimental group.Conclusions: RUSI can be used to provide visual biofeedback, which can promote continuous contraction, and improve the ability to activate the LM and TrA muscles in healthy subjects.
