Background: Bharatnatyam is an Indian classical dance form which have been practiced for a long period of time and is equivalent to any sporting activity. The postures attained during this dance form require good amount of muscle strength and flexibility among the dancers. There is lack of research on flexibility of backline and lower limb strength in bharatnatyam dancers. The overall function of the superficial backline is to support the body in full upright extension and impacts musculoskeletal dynamics. The lumbar lordosis angle and the pelvic inclination angle in bharatnatyam dancers is more than the non-dancers which can affect the backline flexibility. This study analysed if there is any difference, in the lower limb strength and flexibility of backline as compared to participants of same age group.Methods: 10 bharatnatyam dancers and 10 non-dancers between 15 to 30 years participated in this study. Triple hop distance test for both sides and toe touch test was used to check the strength of lower limb and flexibility of backline respectively.Results: There was significant difference in the triple hop distance of right lower limb between bharatnataym dancers and non-dancers. There was no significant difference in the triple hop distance of left lower limb between the two groups. There was not quite significant difference in the toe touch test of between the two groups.Conclusions: There was significant difference in the strength and power of right lower limb of dancers as compared to right lower limb of non-dancers. There was no statistical difference in the left lower limb of both the groups. There was no statistical difference between the flexibility of backline of bharatnatyam dancers and non-dancers.

Foot plantar pressure is the pressure field that acts between the plantar region of the foot and supporting ground. The pressure exerted on the variable region of the foot can be determined using discrete pressure sensors. Information obtained from these sensors is useful in the measurement of gait and posture for diagnosing various problems associated with a lower limb, footwear design, and sports biomechanics. This project is aimed to design a portable in-shoe plantar pressure and gyroscope-based gait angle measurement system. Six Force Sensitive Resistor (FSR) placed in the sole (hallux, 1st, 5th metatarsal, midfoot lateral, midfoot medial and heel respectively) detects the plantar pressure and gyroscope placed at the ankle, knee and hip help measure the orientation and angle of joint movement during various phases of gait. The study among 16 male and 16 female subjects illustrated the significant pressure variation (p<0.0001, t=5.17 with α=95%). Similarly, there was a significant difference in pressure between normal and fast walking speed (p<0.0001, t=5.88) with mean values of 353Kpa and 426Kpa respectively. The mean pressure value for slow walking speed was 423Kpa while there was no significant variation between slow and normal walking speeds (p=0.62, t=1.98). Plantar pressure increased linearly with an increase in the body weight of a person as well. The mean pressure for the 45-50 age group was 313.25Kpa and that for 70-75 was 449Kpa. The study among 10 diabetics and 10 non-diabetic subjects illustrated significantly higher pressure on 1st and 5th metatarsal on diabetic subjects (p=0.0207 and t=2.536). The movement of ankle, knee and hip joint is visualized using the 3D model of a lower limb through processing software. The study illustrated the range of ankle joint movement between -60(dorsiflexion) to 200(plantarflexion), for knee joint was 00 to 300 (flexion) and that for hip joint was -50(extension) to 400(flexion). There was a significant difference in angular values for all three joints while climbing up and down the staircase as compared to walk in a level surface.

The aim of the present study was to demonstrate the cure of elephantiasis over a ten-year follow-up period and novel discoveries with directed occupational rehabilitation. A 66-year-old female patient with a history of bilateral lower limb lymphedema reported the aggravation of the condition over the years, reaching stage III (elephantiasis). The physical examination confirmed elephantiasis. The circumference of the left lower limb was 106 cm. Her body weight was 106 kilograms, height was 160 cm, and the body mass index (BMI) was 41.6 kg/m2. The patient was submitted to intensive treatment for three weeks, which led to a 21-kg reduction in weight and 66 cm reduction in leg circumference. Ten years after treatment, the patient has maintained the results with the compression stockings. Elephantiasis can be cured, although lymphedema cannot. The cure of elephantiasis depends on maintaining the treatment of lymphedema after normalization or near normalization. Directed occupational therapy stimulates the search for new activities and a life closer to normality.

Background: Congenital hypothyroidism (CH) is an endocrine disease with a precocious significant impairment of growth and neuromotor development. Thyroid hormones are essential for central nervous system development, maturation, and myelination. Furthermore, thyroid hormone deficiency affects the function of several systems, including the musculoskeletal system. The disease has a significant incidence in the general population (1:3000–1:2000 newborns in Italy). The aim of the present study was to evaluate any differences in upper and lower limb strength, body sway, and plantar loading distribution in children with CH compared to healthy children. Methods: In this study, the case group was composed of children with CH (CHG), while the control group included healthy children (CG). Both groups comprised 19 children (CHG: female = 12; CG: female = 9). The maximum isometric handgrip strength and explosive-elastic lower limb strength were assessed with the handgrip test and the Sargent test, respectively. The stabilometric and baropodometric analyses were used to measure the Center of Pressure displacements and the plantar loading distribution between feet, respectively. The differences between groups were analyzed by a univariate analysis of covariance using as covariates weight and height with the significant level set at < 0.05. Results: We found that CHG children were shorter and thinner than CG ones (p < 0.05). No significant difference in the upper and lower limb strength was found between groups. CHG exhibited a significant greater Sway Path Length (p < 0.01) and Ellipse Surface (p < 0.05) than CG. Moreover, CHG displayed an asymmetric plantar loading distribution with a significant lower percentage in the right than in the left foot (p < 0.05). Moreover, a significant lower plantar loading percentage in the right foot of CHG than in the right foot of CG was observed (p < 0.05). Conclusions: These findings seem to suggest that CH does not affect muscle strength in early treated children. However, these patients show poor postural control ability and asymmetric plantar loading distribution. Increasing the physical activity in these children could improve their body posture.

Mobility is the basic character of life that depends on the structural as well as the functional character of the body. As age advances, while proper nutrition is not available, the body loses its qualitative capacity for structure and function. Janu Sandhigata Vata has been explained classically by Acharyas and its lakshanas are Vata Poorna- dhrithi Sparsha, Sandhi Shotha, Sandhi Shoola and the presence of Vedana during Prasarana and Aakunchana. The lakshanas of Janu Sandhigata Vata is found to be congruent with Osteoarthritis of the Knee. Research statis- tics have shown that in India, 22% of the population shows Osteoarthritis and females slightly dominate in the incidence. Abha Guggulu and Yogaraja Guggulu are two formulations that contain the drugs of Vatahara, Shothahara, Vedanasthapaka property which will help in the management of Janu Sandhigata Vata. Methods: It was a single-blind randomized comparative clinical trial. The study was conducted on 40 subjects for 30 days. Observations were analyzed and findings were evaluated by using statistical methods. Results: The severity of symptoms markedly reduced in both the groups which is statistically significant and on comparing the effect be- tween Abha Guggulu and Yogaraja Guggulu, there was no statistical difference obtained. Conclusion: The result suggests that both Abha Guggulu and Yogaraja Guggulu had a significant effect on Janu Sandhigata Vata There was no significant difference in the effect of Abha Guggulu and Yogaraja Guggulu. Keywords: Janu Sandhigata Vata, Abha Guggulu, Yogaraja Guggulu

Body expresses its existence because of mind that emotes, similarly mind needs body as media for the ex-pression of its existence. Thus, Mind, Body and Spirit coordinate with each other for balancing functionali-ty in humans and promote health. Dance is one of the mediums that bring synchronization or the coordina-tion between them. The neurological, muscular and emotional elements of the body respond to dance in all constructive ways. The article analyzes all those components that help mind and emotions to remain well composed by regular dance practice. The focus or concentration, the mental activity and tolerance, the pa-tience and stability are all brought into the person by practicing dance. In this study special emphasis is giv-en to Indian classical dance forms as it involves both vigorous as well as delicate foot works and it also has vast array of hand gestures to make dancing more interesting and graceful to practice.

Background : Indian classical dance has since long been practised in India. Kathak and Bharatnatyam are two of the commonest dance forms in India which involve taping of the feet. Impact forces produced during dancing may cause biomechanical change in the feet which in turn cause injury to various ligaments, tendons and fascia affecting balance and intricate movements of the feet. Method : Foot evaluation of 44 Kathak Dancers, 44 Bharatnatyam Dancers and 44 Non Dancers in the age group of 15-25 years was done using Foot Posture Index – 6 Scale and the Groups Were Compared using Non Parametric ANOVA Test . Conclusion: There was no significant difference in foot of Kathak and Bharatnatyam Dancers .However Foot of Dancers deviated from that of Non Dancers.

Acute bacterial skin and skin structure infections (ABSSSI), also referred to as skin and soft tissue infections, or skin and skin structure infections, with or without osteomyelitis (OM) in diabetic foot are complications of diabetes. Quinolones are a widely used class of antibiotics in ABSSSI and OM, and photosensitivity is among their adverse reactions. Its appearance may falsely indicate treatment failure. We describe 2 such cases. The first patient is a 49-year-old male with type 2 diabetes mellitus (DM), who presented with left lower limb ulcer with fever (39 °C) over a week. He began treatment with ciprofloxacin, clindamycin, and linezolid. Although his clinical condition and laboratory tests improved, the redness of the left lower limb increased. Clinical examination revealed redness on the face and the parts of the body that had been exposed to sunlight. The patient continued the same antimicrobial therapy and was given instructions to avoid exposure to sunlight. Redness and infection improved, and the patient was discharged. The second case is a 72-year-old male with a history of type 2 DM, admitted to hospital because of an infected ulcer of the first toe of the right limb. The patient received intravenous treatment with levofloxacin and clindamycin. On the fourth hospital day, the patient presented redness (with eczematous plaques) on his left lower limb. Clinical examination revealed that the patient’s bed was placed near a window and his left limb was exposed to direct sunlight. Patient’s bed was changed to avoid sun exposure. Symptoms began to improve over the next few days.

Jumping ability is considered a determinant of performance success. It is identified as one of the predictors and talent identification in many sports and dance. This study aimed to investigate the effect of 16 weeks of lower-limb strength training on the jumping performance of ballet dancers. A total of 24 participants from the same dance school were randomly selected in the control group [CG; n = 10; aged 13.00 (1.49) years; 43.09 (9.48) kg and 1.53 (0.11) m] and the intervention group [IG; n = 14; aged 12.43 (1.45) years; 38.21 (4.38) kg and 1.51 (0.07) m], evaluated before and after the applied strength training program mainly using the body weight of each participant. Jump performance was assessed using MyJump2, a scientifically validated mobile phone app. Intergroup and intragroup comparisons were assessed, and the magnitude of change was calculated using the effect size (ES). While CG significantly decreased the relative power over time (p &lt; 0.001, ES = −0.29: small), results from the intragroup comparisons suggest that IG significantly increased the countermovement jump (CMJ) height (p &lt; 0.001, ES = 1.21: large), the relative force (p &lt; 0.001, ES = 0.86: moderate), maximal velocity (p &lt; 0.001, ES = 1.15: moderate), and relative power (p &lt; 0.001, ES = 1.37: large). We concluded that a 16-week strength training program of lower limbs is an effective way to improve CMJ height in young dancers. Supplementary strength training appears to be the determinant for the improvement of the jumping performance of ballet dancers.

Objective Exercise-induced oxidative stress is due to the massive increase in free radicals caused by strenuous exercise, which exceeds the ability of self-clearing. It is one of the main causes of sports injury and sports fatigue. Eliminating excessive production of free radicals is the key to alleviating exercise induced oxidative damage. Therefore, the purpose of this study is to study the effect of hydrogen on exercise-induced oxidative damage, to explore its possible mechanism and to explore the best dose of hydrogen with different concentrations. Methods 40 male SD rats (200±20g) were randomly divided into five groups(n=8):sedentary, exercise control, low concentration hydrogen with exercise(H1), medium concentration hydrogen with exercise(H2), high concentration hydrogen with exercise(H3). The rats performed high-intensity exercise for 4 weeks, except the sedentary. rats that with Low, medium and high concentration hydrogen were placed in a hydrogen atmosphere with a concentration of 0.5%, 1% and 1.5% for 1 h immediately after each exercise (keeping the concentration of oxygen and nitrogen in the environment the same as those in the air). The rats were weighed weekly during the experiment. The next day after 4 weeks of training, the samples were collected, and the contents of total superoxide dismutase (T-SOD), catalase (CAT), total antioxidant capacity (T- AOC) and malondialdehyde (MDA) were determined respectively. Results The weight of exercise control was significantly lower than sedentary in the third and fourth weeks of exercise (P<0.05). Compared to sedentary rats, there was no significant difference in the weight of rats between H1, H2 and H3 group. The contents of T-AOC, CAT and T-SOD in exercise control were significantly higher than those in sedentary (P<0.05). The content of CAT in H2 group was significantly decreased compared with exercise control (P<0.01). Compared with exercise control, the T-AOC and T-SOD in the H2 group showed a downward trend but no statistical difference (P>0.05), there was no significant difference between the above indexes, compared with sedentary. In addition, there was no difference in T-SOD and CAT content between H1 group and exercise control; Compared with exercise control, there was no significant difference in T-SOD, T-AOC and CAT in H3 group. At the MDA level, each exercise group increased significantly compared with the sedentary (P<0.05), and the MDA levels in the H1, H2, and H3 groups were decreased compared with the exercise control, but there was no statistical difference. Conclusions It can be seen from the above results that different concentrations of hydrogen intervention can improve the weight loss of rats after intensive exercise. More importantly, the dosage and effect of 1% concentration of hydrogen is easier to remove the excessive radicals produced by intense exercise in the body, avoid the aggravation of oxidative stress, and have very good therapeutic effect. It provides a theoretical basis for the further study of the application of hydrogen in exercise oxidative damage.
