“…Knee extension strength was measured using a hand-held dynamometer (μ-TAS F-1; ANIMA Corporation). The measured force was changed to torque by multiplying the length of lower leg, and normalized by the body weight (Nm/kg)14 ) . Two self-report questionnaires were used, the Japanese version of the Euro QOL (EQ-5D)15 ) and the 25-question Geriatric Locomotive Functional Scale (GLFS-25)16 ) , with participants completing the questionnaire independently.…”

[Purpose] To evaluate the effect of a home exercise program on physical function in community dwelling elderly with pre-sarcopenia or sarcopenia. [Subjects and Methods] Fifty-two community-dwelling individuals, over 60 years and meeting the diagnostic criteria for pre-sarcopenia or sarcopenia, were randomly assigned to intervention group (n=34) and control group (n=18). The intervention group completed 6-months home exercise programs, combining walking with lower limb resistance exercises. Body mass index, skeletal mass index, body fat percentage, handgrip strength, single-leg standing, walking speed (comfortable and maximal), and knee extension strength were evaluated at baseline and post-intervention. Activity was assessed using the 25-question Geriatric Locomotive Functional Scale (GLFS-25) and quality of life using the Euro QOL questionnaire. [Results] Pre- and post-training assessments were completed by 76.5% and 77.8% of participants in the intervention and control groups, respectively. The intervention improved single-leg standing (60.5 s to 77.2 s) and knee extension strength (1.38 Nm/kg to 1.69 Nm/kg). In the control group, maximum walking speed (2.02 m/s to 1.86 m/s) and GLFS-25 score (2.9 to 5.1) worsened. Change of pre-sarcopenia/sarcopenia status was comparable for the intervention (15.4%) and control (14.3%) groups. [Conclusion] A 6-month home exercise program improved physical function in community-dwelling individuals with pre-sarcopenia or sarcopenia.

“…Grip strength and knee extension strength were measured using handheld dynamometers (T.K.K5401; Takei Scientific Instruments, Tokyo, Japan; and μ‐tus F‐100; ANIMA, Tokyo, Japan). A previous validation study showed that interrater reliability of isometric knee extension strength measurements was highly correlated with the data measured by the handheld dynamometers (intraclass correlation coefficient: men and women = 0.99, respectively). Gait speed was measured using a stopwatch in time units of 0.01 s. Participants were asked to walk straight ahead for 11 m at their usual walking speed.…”

Accumulation of advanced glycation end‐products (AGEs) is thought to contribute to muscle weakness in a diabetic animal model. Skin autofluorescence is a proposed marker for accumulation of AGEs in the skin. We aimed to investigate the relationship between AGEs accumulation, sarcopenia and muscle function of Japanese patients with type 1 diabetes. A total of 36 patients with type 1 diabetes participated in the present cross‐sectional study. Sarcopenia parameters (skeletal muscle mass index and knee extension strength) were compared with subcutaneous AGEs accumulation using skin autofluorescence. The prevalence of sarcopenia and impaired knee extension strength was 16.6% (men 0.0%, women 22.2%) and 47.2% (men 22.2%, women 55.6%), respectively. Knee extension strength was negatively correlated with skin autofluorescence (r² = 0.14, P < 0.05), but not with skeletal muscle mass index. In conclusion, the AGEs accumulation might be one of the reasons of impaired lower limb muscle function in Japanese patients with type 1 diabetes.

[Purpose] The purpose of this study was to assess the relationships between bilateral knee extension strengths and gait performance in subjects with poststroke hemiparesis and to predict gait performance by the paretic and nonparetic knee extension strength. [Subjects and Methods] This was a correlational study in which 238 consecutive inpatients with poststroke hemiparesis were enrolled. Knee extensor muscle strengths in paretic and nonparetic lower limbs were measured with a handheld dynamometer, and the presence or absence of impaired gait was also determined. [Results] The mean strength in the paretic lower limb was 0.90 Nm/kg, and that in the nonparetic lower limb was 1.24 Nm/kg. Discriminant analysis classified the difference between the possibility and impossibility of gait by knee extensor muscle strength (standardized discriminant coefficient: paretic, 1.32; nonparetic, 0.55). Thus, paretic and nonparetic knee extension strengths were integrated in the strength index. A threshold level of 2.0 provided the best balance between positive and negative predictive values for the strength index. [Conclusion] The results indicated that both paretic and nonparetic knee extension strengths were related to gait performance. The strength index deduced from bilateral knee extension strengths may serve as a clinically meaningful index for rehabilitation assessment and training.
