Balance Ability

This study evaluates the static balance ability of human body based on a lower limb rehabilitation robot. According to the balance parameters obtained from the movement trajectory of the center of human pelvis, SPSS statistical software was used to verify that there was a significant difference between the two groups ( p < 0.01 ). Principal component analysis is used to allocate the weight of each parameter and establish the comprehensive evaluation value. The comprehensive evaluation value of the control group was 0.383 ± 0.038, and the experimental group was 0.875 ± 0.136. When the subject’s comprehensive evaluation value is between 0.739 and 1.011, it indicates the presence of balance dysfunction, and when it is between 0.345 and 0.421, it indicates that the balance of the lower limbs of the subject is normal. Experimental results show that this evaluation method can objectively and quantitatively reflect the static equilibrium state of human body.

The purpose of this study is to compare and analyze the kinematic characteristics of the upper limb segments during the archery shooting of Paralympic Wheelchair Class archers (ARW2—second wheelchair class—paraplegia or comparable disability) and Paralympic Standing Class archers (ARST—standing archery class—loss of 25 points in the upper limbs or lower limbs), where archers are classified according to their disability grade among elite disabled archers. The participants of this study were selected as seven elite athletes with disabilities by the ARW2 (n = 4) and ARST (n = 3). The analysis variables were (1) the time required for each phase, (2) the angle of inclination of the body center, (3) the change of trajectory of body center, and (4) the change of the movement trajectory of the bow center by phase when performing six shots in total. The ARW2 group (drawing phase; M = 2.228 s, p < 0.05, holding phase; M = 4.414 s, p < 0.05) showed a longer time than the ARST group (drawing phase; M = 0.985 s, holding phase; M = 3.042 s), and the angle of the body did not show a significant difference between the two groups. Additionally, in the direction of the anteroposterior axis in the drawing phase, the change in the movement trajectory of the body center showed a more significant amount of change in the ARW2 group than in the ARST group, and the change in the movement trajectory of the bow center did not show a significant difference between the two groups.

The purpose of this study was to examine the effects of active video games Nintendo Wii and Wobel Board balance exercises on static balance development in children aged 6 years.          54 children, participated in the research voluntarily on informed consents from according to Helsinki criteria by taking permission from Mersin University Ethics Committe. The study was carried out with 3 groups with similar physical characteristics (mean age = 6,21, mean weight= 21,3, mean height = 116,8). The balance training were applied to a group with a 'wobble board' and another group with a 'nintendo wii game console' from active video games. The pre and post test static balance measurements of all groups were measured using the 'Balance Error Scoring System' and the differences between the groups were examined. For parametric results, 3x2 repetitive measurements were performed with anova analysis, and for non-parametric results kruskall wallis test was applied.         There was no significant difference between the groups participating in active video game and wobble board balance training in the measurements made after the study (p>,05). The difference between the experimental group and the foot and tandem position were found statistically significant. (p <,01). There was no significant difference between the two groups in paired feet values (p>, 05).         Both the wobbel board and the active video game training have been found to improve the static balance in children. It has been seen that there is no meaningful development in the control group. This result shows us that active video games are as effective as balance training in 6 years old children. In this context, active video games can be proposed as an alternative method to improve balance.Extended English summary is in the end of Full Text PDF (TURKISH) file. Özet Bu çalışmanın amacı, 6 yaş çocuklarda aktif video oyunları nintendo wii ve wobble board denge antrenmanlarının statik denge gelişimleri üzerine etkisini incelemektir.        Araştırmaya, 54 çocuk, Mersin Üniversitesi etik kurulundan izin alınarak Helsinki kriterlerine uygun olarak katılmıştır. Çalışma benzer fiziksel özellikte (yaş ort.=6,21, kilo ort.=21,3, boy ort.=116,8) 3 grupla  yürütülmüştür. Denge antrenmanları haftada üç gün 8 hafta ‘wobble board’ denge tahtası ve aktif video oyunları ‘nintendo wii oyun konsolu’ ile uygulanmıştır. Kontrol grubuna ise herhangi bir uygulama yaptırılmamıştır. Tüm grupların statik denge ölçümleri ‘Denge Hata Skoru Sistemi’ kullanılarak ölçülmüştür.Parametrik sonuçlar için, çalışmada 3x2 tekrarlı ölçümler anova analizi yapılmış, non-parametrik sonuçlar için ise kruskall wallis testi uygulanmıştır.       Araştırma sonrasında aktif video oyunu ve wobble board denge antrenmanına katılan gruplar arasında istatistiksel olarak manidar fark bulunmamıştır (p>,05). Deney gruplarının, zeminde ve köpükte tek ayak ve tandem duruşlarda bulunan fark kontrol grubuna göre istatistiksel olarak anlamlı (p<,01) iken, çift ayak değerlerinde, üç grup arasında da anlamlı bir fark bulunmamıştır (p>,05).       Hem wobble board hem de aktif video oyunları nintendo wii denge antrenmanlarının çocuklarda statik dengeyi geliştirdiği bulunmuştur. Kontrol gurubunda ise anlamlı bir gelişimin olmadığı görülmüştür. Bu sonuç bize aktif video oyunlarının 6 yaş grubu çocuklarda denge antrenmanları kadar etkili olduğunu göstermektedir. Bu bağlamda aktif video oyunları dengeyi geliştirmek için alternatif bir yöntem olarak önerilebilir.

Objective To evaluate the utility of entheseal ultrasonography and serum COMP in the preclinical diagnosis of psoriatic arthritis. Methods 60 psoriatic patients were divided into: 30 patients with psoriasis (group I) and 30 patients with psoriatic arthritis as control (group II). They underwent independent clinical and ultrasonographic examination of both lower limbs at the calcaneal insertions of Achilles tendons. Psoriatic arthritis disease activity and severity was assessed by modified DAS28 and Steinbrockers scores. Serum levels of COMP were measured for all patients by ELISA. Results On clinical examination, no entheseal abnormalities were detected in group I while they were present in 23.3% of group II with statistically significant difference between them ( P < 0.001). Ultrasonographic entheseal abnormalities were detected in 33.3% of group I and in 46.7% of group II with no significant difference between them ( P > 0.05). Serum COMP were significantly elevated in group I and II with no statistically significant difference between them (mean ± SD 5.9 ± 3 and 6.8 ± 12 respectively, P > 0.05). Entheseal ultrasound was more specific (67%) while serum COMP was more sensitive (87%) in the preclinical diagnosis of psoriatic arthritis. Serum COMP levels were significantly correlated with CRP in both groups and with DAS28 and Steinbrockers scores in group II ( P < 0.01). Conclusion Entheseal ultrasonography and serum COMP levels may be used complementary to each other for preclinical diagnosis of psoriatic arthritis. Serum COMP seems to be promising prognostic marker for psoriatic arthritis patients.

Balance ability is a necessary exercise factor required for the activities of daily living. This study investigated the effects of short-term complex exercise (CE) and core stability exercise (CSE) on balance ability and trunk and lower-extremity muscle activation on healthy male adults. Twenty-nine healthy male adults were included. All performed CE and CSE for 1 min each; the exercise order was randomized. The primary and secondary outcomes were balance ability and muscle activation, respectively. In balance ability, CE showed a significant difference in all variables in both eye-opened and eye-closed conditions compared with the baseline (p < 0.05). In comparisons among exercises, the path length and average velocity variables showed a significant decrease in the eye-opened condition, and the path length variable showed a significant decrease in the eye-closed condition (p < 0.05). In muscle activation, CE showed a significant increase in the gluteus medius (Gmed) and decrease in the rectus femoris (RF), tibialis anterior (TA), and RF/biceps femoris (BF) ratio in the eye-opened condition compared to the baseline and a significant decrease in RF and RF/BF ratio in the eye-closed condition (p < 0.05). Both CE and CSE improved the static balance ability. Furthermore, muscle activation significantly increases in Gmed and decreases in the RF, TA, and RF/BF ratio. Therefore, we recommend including CE in an exercise program that has the purpose of improving static balance ability.

This study was conducted to investigate the effects of balance training with electromyogram-triggered functional electrical stimulation (EMG-triggered FES) to improve static balance, dynamic balance, and ankle muscle activation in stroke patients. Forty-nine participants (>6 months after stroke) were randomly assigned to the experimental group (n = 25) and the control group (n = 24). The experimental group underwent balance training with EMG-triggered FES for 40 min a day, 5 days a week, for a 6-week period in addition to general rehabilitation. The control group underwent balance training without EMG-triggered FES along with conventional therapy. Outcome measures included static balance ability, dynamic balance ability, and leg muscle activation. The static and dynamic balance abilities were significantly improved after intervention in both groups (p < 0.05), although the experimental group showed considerably greater improvement than the control group (p < 0.05). Leg muscle activation on the affected side resulted in significant improvements in the experimental group (p < 0.05) when compared with baseline but not in the control group. Balance training with EMG-triggered FES is an acceptable and effective intervention to improve the static balance, dynamic balance, and ankle muscle activation in stroke patients.

This study aimed to determine the efficacy of Integrated Rehabilitation Techniques of Traditional Chinese Medicine (IRT-TCM) on patients with ischemic stroke as an alternative therapy to conventional rehabilitation techniques. Sixty-nine patients with ischemic stroke were randomly assigned to receive either IRT-TCM (intervention group, n = 46) or conventional rehabilitation techniques (control group, n = 23). The IRT-TCM consisted of a sequential combination of acupuncture and massage techniques. The Fugl-Meyer Assessment (FMA), National Institutes of Health Stroke Scale (NIHSS), Barthel index (BI) and modified Rankin Scale (mRS) were measured on day 0 (baseline, before treatment), day 21, and day 90. We observed that the scores in FMA and BI were increased, and NIHSS were decreased in both groups on day 21 and 90, compared with the baseline (day 0). Furthermore, significantly better scores in FMA of lower limbs and NIHSS were found in patients treated with IRT-TCM on day 21 and 90. For mRS, the percentage of patients ranking 0 and 1 in the intervention group presented a striking contrast to the control group on day 90 but with no significant difference. The results indicated that, as a feasible alternative therapy, IRT-TCM is beneficial for patients with ischemic stroke. Further research with larger sample size, long-term observation, and strict blinding are still in need to confirm the efficacy of IRT-TCM.

Objectives: Walking and balance control are determining factors in the independence of the elderly because they are the main components of daily physical activity. This study evaluated the effectiveness of Dynamic Neuromuscular Stability (DNS) training on balance and gait function in the elderly. Methods: This study had a pre-test/post-test design. It was a quasi-experimental study performed on 30 older men aged 60-70 years in Qom Province, Iran, in 2021. The elderly was randomly divided into experimental (n=15) and control (n=15) groups. The Experimental Group (EG) participated in three 45-min sessions of dynamic neuromuscular stability training every week for 6 weeks, and the Control Group (CG) continued their normal daily routine. Berg balance scale (dynamic balance), modified stork stand (static balance), and temporal and spatial gait parameters were used to collect information before and after applying the training protocol. The obtained data were analyzed using ANCOVA statistical method and the paired t test. Results: There were significant differences between pre-test and post-test in EG regarding the variables of dynamic balance, static balance (P=0.001), and gait function, but in the CG, no significant difference was observed for these variables (P>0.05). Also, there was a significant difference between the mean scores obtained in the balance and gait tests between the two groups (P<0.05), and EG performed better in the post-test. Discussion: DNS training due to the great variety of movement in different parts of the body and the effect on improving strength, flexibility, range of motion, and physical fitness can also improve balance and gait function in the elderly. According to the present study results, one of the best ways to reduce the costs and physical, psychological, and social problems caused by aging is to use DNS training for the elderly.

Abstract In this study, a valid and comprehensive evaluation method for assessing the quality of Desmodium styracifolium (Osb.) Merr has been established, based on analysis of high-performance liquid chromatography fingerprint combined with the similarity analysis (SA), hierarchical cluster analysis (HCA), principal component analysis (PCA), discriminant analysis (DA) and the quantitative analysis multi-components by single marker (QAMS) method. Eleven peaks of the common model were obtained and analyzed using SA, HCA, PCA and DA analysis. These methods indicated a similar conclusion that 31 batches of D. styracifolium samples were categorized into two clusters basically coincident with their geographical regions of origin. Four peaks were identified as schaftoside, isoorientin, isoschaftoside and isovitexin. Schaftoside was selected as the internal standard, and the relative correction factors between schaftoside and the other three flavonoids were calculated using the QAMS method. The accuracy of the QAMS method was verified by comparing with the results calculated by the external standard method. No significant difference between the two methods was found. In conclusion, the established methods were scientifically applied in the quality evaluation of D. styracifolium.
