ABSTRACT
Background: The present study will help to determine if balance in young females is affected due to donning of headscarf and will help in planning preventive strategies. Material & Methods: Study Design- Cross sectional study design, Setting- Subjects were selected from Jamia Hamdard, New Delhi -110062. Subjects were selected for the study according to the following inclusion and exclusion criteria. Methods of Sampling- Sample of convenience. Instrumentation/Tools/Scales- Goniometer, Standardized tape measure, Weighing machine, Stadiometer and Y Test Kit. Statistical Analysis-The data was managed on an excel spreadsheet and was analysed using SPSS (Statistical Package for Social Sciences for windows) software, Version 20. Student’s t-test was used to analyse the data and level of significance was kept at 0.05. Results: The purpose of conducting this study was to find out the effect of wearing head scarf on dynamic balance, which was conducted on females of Jamia Hamdard. This study was conducted on 98 young adult female university students. Out of which 49 subjects wore headscarf (Experimental group) for at least 1-year and rest 49 subjects did not wear a headscarf (Control group) It was observed that there was a statistically significant effect of wearing headscarf on dynamic balance in young adult females between the two groups. Conclusion: The present study was conducted to see the effect of donning a headscarf on balance in young females. A total of 98 subjects were included in the present study and divided into the control and experimental group. The results of the study indicated that the control group had better balance as compared to the experimental group by Y balance test indicating that donning of headscarf affects balance in young females. Hence null hypothesis is rejected and experimental hypothesis is accepted.
ABSTRACT
ObjectiveTo investigate the characteristics of electromyography (EMG) and postural stability of lower limb muscles during Y-balance test (YBT) and their relationship. MethodsFrom October to November, 2021, a total of 26 female students aged 18 to 22 years were recruited from Binzhou Medical University to complete YBT; while the EMG of rectus femoris, biceps femoris, tibialis anterior and gastrocnemius of supporting legs were collected synchronously to measure root mean square (RMS), integral electromyography (iEMG), and muscle contribution rate; and the postural stabilities were measured with three-dimensional force platform, to record total, antero-posterior (A/P) and medio-lateral (M/L) path length of center of pressure (COP). ResultsIn three directions of YBT, the RMS of rectus femoris was the most (χ2 > 56.952, P < 0.001), and the iEMG and contribution rate of the tibialis anterior were the most (χ2 > 38.507, P < 0.001). All the path length of COP was the shortest in the anterior (P < 0.05). In the anterior, the total path length of COP correlated with iEMG of biceps femoris (r = 0.452, P = 0.02) and gastrocnemius (r = 0.397, P = 0.045); in the postero-medial, the total path length of COP correlated with iEMG of gastrocnemius (r = 0.478, P = 0.014); and in the postero-lateral, the total path length of COP correlated with iEMG of tibialis anterior (r = 0.437, P = 0.026). ConclusionFor YBT, the activation of rectus femoris, tibialis anterior and gastrocnemius muscles of supporting legs are significant, and different with the indicators of EMG. Postural stability is the best in the posterolateral. The joint extensors or flexors play a different role for dynamic postural stability in the different directions.
ABSTRACT
El objetivo es verificar si existe relación entre la probabilidad de lesión en extremidades del tren inferior y el índice de grasa corporal en estudiantes que participan de talleres deportivos en la Universidad Adventista de Chile. Participaron 66 alumnos entre las áreas deportivas voleibol, básquetbol, fútbol y hándbol por un método de muestreo censal. Todos los participantes de la investigación fueron evaluados por medio del instrumento "Y balance Test", para verificar si son propensos a sufrir una lesión de tren inferior y además se les realizó una evaluación antropométrica para conocer su índice de grasa corporal. Los resultados no encontraron correlación entre porcentaje de grasa y probabilidad de lesión, sin embargo, se encontró correlación entre probabilidad de lesión entre una pierna y otra
The objective is to verify if there is a relationship between the likelihood of limb injury in the lower body and the body fat index in students participating in sports workshops at the Adventist University of Chile. 66 students participated in sports areas such as volleyball, basketball, soccer and handball by a census sampling method. All the participants of the investigation were evaluated by means of the "Y balance Test" instrument, to verify if they are prone to suffer a lower train injury and also an anthropometric evaluation was done to know their body fat index. The results did not find correlation between fat percentage and injury probability, however, a correlation was found between the injury probability between one leg and the another

[Purpose] It has been reported that foot warming can improve flexibility and standing balance. The purpose of this study was to examine the effects of plantar warming, skin temperatures, feet sensations, and plantar flexibility on balance ability. [Methods] Study participants included 30 healthy young adults for both the warmed and non-warmed conditions. Plantar warming was carried out for 15 minutes using a foot heater. Deep temperatures (1-2 and 4-5 metatarsal bones on the dorsal-side of the foot) and surface skin temperatures of the dorsal-side (lateral 5th metatarsal head on the right and left feet), Y Balance Test (YBT), and area of one leg stance (OLS) postural sway were measured before and after warmed/non-warmed conditions, and also after 10 minutes (after10) warmed/non-warmed conditions. Semmes Weinstein monofilament (tactile sense), vibration sense, contact area of the plantar on OLS tests and toe extension angle value were measured before and after warmed/non-warmed conditions. Change ratios were calculated for non-temperature items and compared using repeated measures analysis of variance and Wilcoxon’s signed rank test. [Results] Deep temperature, surface skin temperature of dorsal, and surface skin temperature of the plantar were significantly increased by warmed condition. After- and after10-warmed YBT reaching distances increased significantly compared with before-warmed distances for both the warmed and non-warmed conditions. No significant differences were found between before- and after-warming OLS postural sway area, Semmes Weinstein monofilament, vibration sense, and OLS plantar contact area results. Change ratios of YBT and toe extension angles were significantly increased in the warmed condition compared with the non-warmed condition. [Discussion and Conclusions] YBT, an index of dynamic balance ability, was significantly increased after the plantar of the foot was warmed, confirming that foot warming does indeed improve balance. We also be observed significant increases in skin temperature and toe extension angles, but no significant changes in OLS postural sway area, Semmes Weinstein monofilament, vibration sense, and OLS plantar contact area. Increased YBT and expansion of toe extension angles suggest that plantar flexibility can be improved by applying a dynamic stretching stimulus after warming of the plantar, which will also enhance balance abilities.

ABSTRACT
Background: Osteoarthritis (OA) is a chronic degenerative joint disease with a prevalence of about 29% in India. Reduced kinesthetic receptors in joint especially around the ligaments in the knee can lead to impaired proprioceptive information to an individual. Core muscle endurance deficiency leads to an increase in the loading of the knee, as well as in knee joint contact force during dynamic movement. Hence, poor core stability may be one of the contributing factors that lead to knee OA development as well as its progression. Objectives: The objective of this study was to find a correlation between core muscle endurance and balance in subjects with OA. Material and Methods: The observational study was conducted on 50 healthy, male and female subjects, age >40 years diagnosed with OA knee using convenience sampling. Subjects underwent core stability assessment consisting of plank, bilateral side bridge, Sorenson, and 60-degree trunk flexion endurance tests. Y-balance test -Lower quarter (YBT-LQ) was used to measure dynamic balance in individuals. The data were analyzed at a 5% level of significance using SPSS. Outcomes were correlated using Spearman’s correlation of coefficient. Results: Correlation was found between YBT-LQ and plank r = 0.402 (P = 0.004), YBT-LQ and right side bridge 0.425 (P = 0.002), YBT-LQ and left side bridge r = 0.490 (P = 0.001), YBT-LQ and 60° trunk flexion test r = 0.369 (P = 0.008), and YBT-LQ and Sorenson test r = 0.324 (P = 0.022). Conclusion: There is a weak to moderate correlation between core endurance and balance in subjects with OA knee.
ABSTRACT
Background: Older females have less dynamic postural control and muscle strength than do middle-aged females. Aging-related strength losses may limit balancing performance. Objective: The purpose of this study was to investigate the ability of the Y Balance Test (YBT) and lower limb strength to discriminate between females in 2 age groups, the relationship between YBT distance and the Berg Balance Scale (BBS), and the degree to which performance on YBT distance is related to lower limb strength in middle-aged and older females. Method: The 40 healthy, independently active females were divided into 2 groups: older and middle-aged. The participants underwent measurements of YBT distance using the YBT, maximal muscular strength of the lower limbs using a handheld dynamometer, and the BBS. Results: The YBT distance in 3 directions and lower limb muscle strength for both lower limbs were significantly lower in the older adults than in the middle-aged group. A moderate correlation but insignificant correlation was found between the YBT composite distance and the BBS score. In the older females, YBT distance was significantly positively correlated with strength of the knee flexor and hip abductor. In the middle-aged group, YBT distance was significantly positively correlated with strength of the knee flexor and hip extensor. Conclusions: Performance on the YBT was influenced by the strength of lower limb. We suggested that YBT can be used to alternative as a measurement of dynamic balance. Proper training programs for older people could include not only strengthening exercises but also YBT performance to improve balance. .
