Abstract

We measured the muscle mass and phase angle of each body part to evaluate the relationship between balance and gait functions in individuals with a pre-frailty status. This cross-sectional observational study determined the skeletal muscle mass-to-body weight ratio and phase angles of 21 control (robust) and 29 pre-frail subjects. Their Brief-Balance Evaluation Systems Test, Timed Up-and-Go (TUG) test, Life-Space Assessment, and Modified Fall Efficacy Scale scores plus the relationship between muscle mass, phase angle, and motor function were evaluated. In the pre-frailty group (three males, 26 females, aged 75.58±7.60 years), significant correlations were noted between the Brief-Balance Evaluation Systems Test score and lower-limb (r=0.614) and wholebody (r=0.557) phase angles, and between the TUG test score and lower-limb muscle mass-to-body weight ratio (r=−0.616), lower-limb phase angle (r=−0.616), and whole-body phase angle (r=−0.527). Evaluating the phase angle of the lower extremities of pre-frail patients and intervening accordingly may help clinicians maintain and improve these patients’ balance and gait functions.

Abstract

Indexes for objectively evaluating abnormal gait in hip osteoarthritis (OA) patients and determining effective interventions are unclear. We analyzed the abnormal gait of hip OA patients by focusing on movements of the trunk and pelvis to establish an effective evaluation index for each direction of motion. We studied 28 patients with secondary hip OA due to developmental dysplasia of the hip and 16 controls. The trunk and pelvic movements during gait were measured in the medial-lateral (x), vertical (y), and back-and-forth (z) directions by a triaxial angular accelerometer. Gait speed, steps, step length, muscle strength, range of motion, and timed up-and-go (TUG) test performance were measured. We determined the correlations between physical function and the index of abnormal gait in the hip OA patients. Movements other than trunk and pelvic motions in the y-direction indicated abnormal gait in the patients. Significant correlations were found between abnormal gait and range of motions (extension, internal rotation), TUG score, stride length, and steps. The TUG test, stride length and steps were important for evaluating abnormal gait in hip OA patients. Individual interventions for each movement direction are required.

Abstract

Purposes: To verify the relationship between muscle volume and muscular strength of different cross-sectional areas (CSAs) of the gluteus maximus and medius, and to clarify the effective evaluation index.Methods: Twenty healthy adults were enrolled in this cross-sectional study. Magnetic resonance images were evaluated, and CSAs of the gluteus maximus and medius were calculated. Calculation sites were the peak CSA, lowest end of the sacroiliac joint CSA, and just above the femoral head CSA. Muscle volume and muscular strength were measured. The correlation between muscular CSA, muscle volume, and muscular strength was verified using Pearson's correlation coefficient (p < 0.05). One-way analysis of variance and the Tukey-Kramer test were used to verify differences in each CSA (p < 0.05).Results: A significantly positive correlation was found between muscular CSA, muscle volume, and muscular strength of both muscles (p < 0.05). For the gluteus maximus, the muscular CSA calculated just above the femoral head showed a significantly larger value than that calculated at the lowest end of the sacroiliac joint (p < 0.05). For the gluteus medius, the peak CSA and muscular CSA calculated at the lowest end of the sacroiliac joint were significantly larger than that calculated just above the femoral head (p < 0.05).Conclusions: The maximum CSA of the gluteus maximus was found just above the femoral head and that of the gluteus medius was near the lowest end of the sacroiliac joint; hence, CSAs should be calculated at these sites. The CSA reflected muscle volume and strength. [ABSTRACT FROM AUTHOR]

Abstract

This study aimed to determine which muscle the gluteus maximus, gluteus medius, gluteus minimus (Gmin), or tensor fasciae latae (TFL) contributes most to hip abduction strength and to identify effective sites for cross-sectional area (CSA) Gmin and TFL measurement in hip osteoarthritis (OAhip) patients. Twenty-eight patients with OAhip were included. The muscle CSA and volume were determined using magnetic resonance imaging. Peak isometric strength was determined using hand-held dynamometry. Muscle volumes were normalized to the total muscle volume of hip abductors. Multiple regression analysis was performed. The difference between the CSA of Gmin and TFL was calculated, and correlations with volume and muscle strength were determined. Gmin volume was related to abductor muscle strength (p=0.042). The peak CSA of the Gmin correlated with muscle volume and strength. The CSA of the TFL correlated with volume, with no difference between the CSA of the most protruding part of the lesser trochanter and peak CSA. Gmin volume was strongly related to abductor muscle strength. Peak CSA is a useful parameter for assessing the CSA of the Gmin among patients with OAhip. The CSA of the TFL should be measured at the most protruding part of the lesser trochanter., Competing Interests: No potential conflict of interest relevant to this article was reported.
