“…This is supported by a previous study that reported that dynamic balance ability was associated with center of pressure displacement time 25 ) . Moreover, previous studies reported that tibialis anterior muscle activity can influence the rear foot to forefoot motion during the stance phase 26 ) , and this muscle showed markedly regressive changes after 60 years of age 27 ) . Because the present participants required assistance in daily life, we could not evaluate their muscular strength.…”

[Purpose] This study evaluated gait parameters and foot pressure in two regions of the feet among older females with different personal care support needs to analyze factors that contribute to higher support requirements. [Subjects and Methods] Thirty-two older females were divided into support-need and care-need level groups. Gait parameters (speed, cadence, step length, step width, gait angle, toe angle, double support phase, swing phase, and stance phase) and foot pressure during a 5-m walk were measured and analyzed in the two groups. [Results] The percentage of the double support phase on both feet and the right stance phase were significantly higher in the care-need level group, while that of the right swing phase was significantly lower than that of the support-need level group. Additionally, the phase showing peak pressure on the left rear foot was significantly delayed and the left forefoot pressure in the terminal stance was significantly lower in the care-need level group than in the support-need level group. [Conclusion] These findings show that the temporal duration parameters and foot pressure on a particular side were significantly different between the two groups and suggest that these differences were associated with a higher care level.

“…Age-related decrease of the number of muscle fibers and their size in the tibialis anterior has been observed in subjects aged 60 years and over (Kimura et al 2002). In this study, we measured muscle weight and muscle fiber size in a 58-year-old subject.…”

“…Data on muscle weight and muscle fiber size in the lower limbs from one single normal subject is indispensable to elucidate the correlation between skeletal muscle morphology and function during the aging process. However, such data have not been published, as far as we know, although age-related changes have been observed on subjects aged 60 years and over (Kimura et al 2002). This study is the first to have been carried out on a 58 years-old subject.…”

Morphological study of the lower limb muscles is necessary for the analysis of muscle function and its relation to the aging process. In this study, we measured the muscle weight and the muscle fiber morphometry (cross-sectional area and total number of muscle fibers at the muscular belly, and muscle fiber size) of the human lower limb in an adult Japanese cadaver (male, 58 years old). The results presented here can provide the normal control data to elucidate the aging process of the human lower limb muscles. The morphological features in the human lower limb muscles were the pronounced enlargement of the gluteus maximus in the hip, the vasti muscles in the thigh and the soleus in the leg.

Management of Chronic Venous Insufficiency of the Lower Extremities Based on Podiatrists’ Opinions

The author is a plastic surgeon specializing in the treatment of chronic lower extremity wounds, but is also responsible for medical care as a podiatrist, promoting our outpatient clinic as "foot outpatient clinic". We have the most frequently encountered patients, with varix-or skin-lesion-free chronic venous insufficiency, complaining of numbness, pain, or swelling. Many patients did not have any obvious venous lesion, and the symptoms may have been related to lower extremity venous hypertension associated with functional lower-limb muscle pump failure related to shortening of the walking time or sedentary behaviors, anterior foot lesion-related digitoplantar dorsiflexion hypofunction, or structural muscle pump failure related to a limitation in the range of motion in the ankle joint. Management involving a combination of phlebology and podiatry is useful for relieving these conditions. Currently, for venous ulcer treatment, the prevention of recurrence is emphasized rather than primary healing. For further amelioration, the management of daily life lower extremity venous hypertension, which cannot be evaluated based on consultation on a hospital visit alone, may also be necessary. To achieve this, the introduction of digital healthcare, such as the assessment of daily motions with IoT devices, is useful
