This note accompanies T. Mart́ınez–Coronado, A. Mir, F. Rosselló and G. Valiente’s work “A balance index for phylogenetic trees based on quartets”, introducing a new balance index for trees. We show here that this balance index, in the case of Aldous’s β ≥ 0–model, convergences weakly to a contraction–type distribution.

Background: This study aimed to investigate the impact of neuromuscular exercises (NE) and local-indigenous games (LIG) on the static and dynamic balance of obese children. Methods: Thirty obese children were randomly assigned to NE (n=15, mean age 10.47 ± 2.1 years, body mass index 29.15 ± 3.01 kg/m2) or LIG (n=15, mean age 10.67 ± 1.52 years, body mass index 29.45 ± 3.41 kg/m2) groups. Both ...

The objective of this study was to evaluate the relationship between the anthropometric factors of height, body mass, body mass index and postural balance and to compare the balance indices between genders in the upright standing position, in healthy adult subjects under conditions of instability. Forty individuals were subjected to functional tests of body stability using the Biodex Balance Sy...

Introduction:   Muscle weakness and balance problems are limiting factors in Multiple sclerosis patients that can be improved due to physical activity. The purpose of this study was to investigate the effect of 8 weeks of aerobic exercise on balance function and Physiological Cost Index in patients with MS in Yazd city in 1394. Methods: This quasi-experimental study was conducted in two stages...

[Purpose] The purpose of this study was to compare the effect of ankle taping and balance exercises on postural stability indices in healthy women. [Subjects and Methods] Thirty healthy female students were randomly assigned into two equal groups: ankle taping and balance exercise. The balance exercise group performed balance exercises for 6 weeks, with 3 sessions per week and each session last...

[Purpose] This study aimed to determine the reliability and validity of our standing balance assessment index using a hand-held dynamometer (the hand-held dynamometer assessment index) in stroke patients. [Subjects and Methods] The participants were 60 stroke patients with impaired standing balance. Intrarater and interrater reliabilities were evaluated employing the intraclass correlation coef...

In a walking cycle design, maximizing the upright balance should be considered in addition to the kinematic constraints, energy consumption rate must be considered. The purpose of this study is to find the optimal step length obtained for each person according to the physical features. In this research, in order to minimize energy consumption rate by considering maximum balance two cost functio...

Data envelopment analysis (DEA) is a technique for measuring the efficiency of decision making units. In all models of the DEA, for each unit under assessment, the numerical efficiency is obtained which may be less than or equal to one. Given the possible large number of functional units, we use various ranking methods for evaluating units. One of the rating methods is Balance index and Topsis....
