ABSTRACT
OBJECTIVE:Chronic ankle instability is mainly characterized by symptoms such as muscle weakness,intermittent pain,and repeated sprains,which seriously affect exercise and daily life.Loss of proprioception,prolongation of fibular reaction time,and weakening of valgus force may be the main symptoms of chronic ankle instability,so exercise intervention can effectively improve the symptoms related to ankle instability.Meta-analysis was used to quantitatively evaluate the effect of balance training on the rehabilitation intervention of chronic ankle instability,providing a reliable theoretical basis and practical basis for chronic ankle instability patients to scientifically formulate exercise prescriptions. METHODS:The randomized controlled trial of balance training on symptom rehabilitation and dynamic equilibrium of patients with chronic ankle instability was retrieved on CNKI,VIP,Web of Science,and PubMed.The literature was published from the inception to November 23,2022.Two reviewers were included to evaluate the quality of the included literature based on the physical therapy evidence scale.The primary outcome measure is the Self Functional Rating Scale,and the secondary outcome measure is the Star Shift Balance Test,both of which are continuous variables.Forest mapping,meta-regression,subgroup analysis,sensitivity analysis,and publication bias evaluation were performed on the included literature using RevMan 5.3 and Stata-SE 15 software. RESULTS:(1)A total of 18 articles of randomized controlled trials were screened and 641 patients with chronic ankle instability were included in the study.Overall,the methodological quality of the literature was relatively high.(2)Meta-analysis results showed that balance training improved the functional rehabilitation effect of chronic ankle instability patients(SMD=0.82,95%CI:0.41-1.23,P<0.000 1).Meta-regression exhibited that intervention time might be the main reason for heterogeneity(P=0.008).(3)The subgroup analysis results revealed that 6 weeks of intervention(SMD=0.98,95%CI:0.31-1.65,P=0.03),more than 3 interventions per week(SMD=0.87,95%CI:0.30-1.44,P=0.003),and each intervention time less than 20 minutes(SMD=0.89,95%CI:0.61-1.66,P<0.000 1)were the best rehabilitation plans to improve the functional rehabilitation effect of chronic ankle instability patients.(4)Meta-analysis results also showed that balance training improved the stretching degree of the anterior side(SMD=0.56,95%CI:0.31-0.80,P<0.05),posterior inner side(SMD=0.88,95%CI:0.45-1.32,P<0.05),and posterior outer side(SMD=0.84,95%CI:0.22-1.46,P<0.05)of the star shift balance test. CONCLUSION:Current clinical evidence shows that balance training can improve ankle instability symptoms and elevate dynamic equilibrium ability in chronic ankle instability patients.It is recommended to intervene more than 3 times a week,with each intervention lasting less than 20 minutes,to achieve better rehabilitation effects.
ABSTRACT
Objective@#To explore the factors affecting balance ability among middle-aged and elderly people with depressive symptoms, so as to provide the evidence for improving balance ability and prevention of falls.@*Methods@#Based on the 2015 database of China Health and Retirement Longitudinal Study (CHARLS), demographic information, lifestyle and health status were collected from people aged 45 years and older who scored 10 and more on the Self-rating Depression Scale or took antidepressants. The balance ability was assessed by semi-tandem and full-tandem stand tests, which was defined as meeting the standard when both tests were completed. Factors affecting the balance ability among middle-aged and elderly people with depressive symptoms were identified using a multivariable logistic regression model.@*Results@#Data were collected from 4 263 participants with an mean age of (60.73±8.53) years, including 1 748 males (41.00%) and 2 515 females (59.00%). There were 1 241 people failed to meet the standard of balance ability test, accounting for 29.11%. Multivariable logistic regression analysis showed that participants who were at ages of 65 years and older (OR=1.234, 95%CI: 1.071-1.421), were female (OR=1.422, 95%CI: 1.161-1.741), were physically disabled (OR=1.309, 95%CI: 1.127-1.521) and had physical pain (OR=1.170, 95%CI: 1.023-1.340) had higher risks of failing to meet the standard of balance ability test, while participants who took naps (OR=0.856, 95%CI: 0.748-0.980), never smoked (OR=0.641, 95%CI: 0.517-0.793) and had social activities (OR=0.864, 95%CI: 0.755-0.988) had lower risks of failing to meet the standard of balance ability test.@*Conclusion@#The balance ability among middle-aged and elderly people with depressive symptoms was associated with age, gender, napping, smoking, social activities, physical disability and physical pain.
ABSTRACT
Objective To explore the difference of balance ability between patients with chronic nonspecific low back pain ( CNLBP) and healthy individuals, and the correlation between patients’ pain symptoms, lumbar flexibility, abdominal muscle endurance, overall function, quality of life and fear of avoidance with balance ability, so as to guide clinical rehabilitation evaluation. Methods A total of 34 patients with CNLBP were selected as the experimental group, and 34 healthy volunteers without history of low back pain were selected as control group. The plantar pressure measurement system was used to collect the ratio of forefoot to hindfoot pressure, pathlength ( L) of plantar center of pressure ( COP), displacement length in anteroposterior direction ( LAP ), displacement length in mediolateral direction (LML ), mean velocity (v), displacement velocity in anteroposterior direction (vAP ), displacement velocity in mediolateral direction (V-ML) and elliptical swing area (S). In addition,the experimental group was assessed by the visual analogue scale (VAS), the finger floor distance (FFD), the number of sit-ups in 1 minute, the Oswestry disability index (ODI), the 36-item short form survey (SF-36) and the fear avoidance beliefs questionnaire (FABQ), and correlated with plantar pressure parameters. Results All plantar pressure parameters were significantly different between the two groups ( P < 0. 05). The the ratio of forefoot to hindfoot pressure in experimental group was significantly lower than that in control group (P<0. 05), and the parameters L, LAP , LML , v, vAP , vML and S were significantly higher than those of control group (P<0. 05). With eyes open or closed, the VAS score of experimental group was positively correlated with L, LAP , LML(P<0. 05), and FFD and FABQ scores were positively correlated with L and LML , respectively (P< 0. 05). With eyes open, ODI was positively correlated with L, LAP and LML (P< 0. 05), and SF-36 score was negatively correlated with L and LML(P<0. 05). With eyes closed, the number of 1-min sit-ups was negatively correlated with LAP and S (P<0. 05), ODI was positively correlated with L and LML(P<0. 05), and the SF-36 score was negatively correlated with L (P<0. 05). Conclusions The static balance ability of patients with CNLBP is decreased, and it is correlated with pain symptoms, lumbar function, quality of life and psychological status. The result can provide references for the assessment of functional activities.
ABSTRACT
Objective:To analyze and evaluate the impact of balance training on patients with chronic obstructive pulmonary disease (COPD).Methods:The randomized controlled trials of balance training in COPD patients in PubMed, Embase, Web of science, the Cochrane Library, CNKI, Wanfang, VIP, and Chinese Biomedical Literature Database were searched. The retrieval time was from the establishment of the database to November 20, 2022. A Meta-analysis was conducted using RevMan5.3 on balance ability, exercise ability, quality of life, and balance confidence in patients with COPD.Results:A total of 432 patients were included in 7 studies. The results of the Meta-analysis showed that compared with other training, balanced training could improve the balance ability of patients [Timed Up and Go Test: mean difference ( MD)=-2.19, 95% CI (-2.86, -1.52); P<0.001, Berg Balance Scale: MD=4.02, 95% CI (0.78, 7.27); P=0.020, the Balance Evaluation Systems Test: MD=7.83, 95% CI (0.13, 15.52); P=0.050], exercise ability [Six-Minute Walk Test: standard mean difference ( SMD)=0.21, 95% CI (0.01, 0.40); P=0.040] and quality of life [COPD Assessment Test and St. George′s Respiratory Questionnaire: SMD=-0.54, 95% CI (-1.08, -0.01); P=0.050], but balance training did not effectively enhance patients′ activity balance confidence [Activities-Specific Balance Confidence Scale: MD=9.34, 95% CI (-0.98, 19.66); P=0.080]. Conclusion:Balance training can improve the balance ability, exercise ability, and quality of life of patients with COPD, but the impact on patients′ activity balance confidence needs to be further verified.
ABSTRACT
Falls occur primarily in elderly individuals, with an annual incidence of about 20.8% in this population group in China, and have become the first cause of injury-related deaths in people aged 65 years and over.Balance ability is an important ability for the elderly to maintain body posture.Good balance ability helps to prevent falls in the elderly.Therefore, it is necessary to understand the factors involved in sensory input, central integration and motor output that affect the balance ability of the elderly and the underlying mechanisms for medical professionals be more knowledgeable about the role played by balance ability in falls of the elderly and timely and targeted intervention, thus effectively reducing the risk and incidence of falls in the elderly.
ABSTRACT
[Objectives]The purpose of this study is to clarify the effect of acupuncture sensation on the body sway during a one-legged stance.[Methods] The study participants were 16 healthy adults (mean age 21.8±1.6 years). The study design was a crossover method, wherein the same individuals participated in the acupuncture stimulation condition and the control condition at intervals of more than one week. Evaluation was performed before and after each intervention by holding a one-legged stance for 40 seconds on a force plate. A total of six items of body sway were measured, including: circumferential area, rectangular area, effective value area, total trajectory length, unit trajectory length, and unit area trajectory length. In addition, Visual analog scale (VAS) was used to evaluate the ease with which the lower leg was subjected to force during measurement. In the acupuncture stimulation condition, single acupuncture was performed on the lower limb muscle group of the measuring leg, and the VAS of the acupuncture sensation was evaluated at the time of stimulation and at the end of measurement. Stainless steel disposable acupuncture needles (length: 50 mm, diameter: 0.20 mm.) were used for stimulation. The stimulation sites were the ST32, ST37, BL37, BL57, and GB37 of the test leg, and acupuncture needles were inserted to the desired depth and removed when sensation was felt. The control condition was the supine position for five minutes. Comparisons were made between the pre- and post-acupuncture stimulation conditions and the pre- and post-control conditions(body sway, lower leg VAS, acupuncture sensation VAS). [Results] There was no significant difference between the two conditions in terms of body sway. However, the VAS of lower limb effort was significantly lower, from 78.0±14.9 mm to 63.1±17.0 mm before and after the intervention (p<0.05). On the other hand, in the control condition, there was no significant difference from 79.5±12.3 mm to 75.2±12.7 mm before and after rest. The VAS of acupuncture sensation was 50.4±14.3 mm during stimulation and 9.8±9.0 mm at the end of measurement, which was significantly lower (p<0.05). [Conclusion] Acupuncture sensation did not affect the body sway before and after acupuncture stimulation. However, the subjective sensation of weakness appeared, suggesting that acupuncture stimulation may cause a transient sensation of weakness.

The control group implemented traditional exercise on the basis of routine nursing. The experimental group received 8-week and 24 times sensorimotor training on the basis of the routine nursing. The Chinese version of the Mini Mental State Examination (MMSE) was used to assess the cognitive level of patients, the Modified Morse Fall Scale (MMFS) was used to assess the risk of falls, and the Berg Balance Scale (BBS) was used to assess the balance function.Results:After 8 weeks of intervention, the total score of MMSE was (26.72 ± 1.71), higher than the total score of the control group (22.36 ± 1.93), the factor scores of temporal orientation, spatial orientation, recollection, attention and calculation, memory and language ability in the experimental group were (4.90 ± 0.31), (4.72 ± 0.53), (2.86 ± 0.35), (4.66 ± 0.61), (2.83 ± 0.47), (6.76 ± 1.09), higher than scores of the control group (4.36 ± 0.56), (3.93 ± 0.66), (2.57 ± 0.50), (3.64 ± 1.03), (2.18 ± 0.67), (5.68 ± 1.02), and the difference was statistically significant( t values were 2.53-9.06, all P< 0.05). The total score of MMFS in the experimental group was (5.93 ± 1.49), which was lower than that in the control group (8.75 ± 2.30). The difference was statistically significant ( t=-5.51, P<0.01). The total score of BBS in the experimental group was (38.83 ± 1.71), which was higher than that in the control group (30.89 ± 1.93). The difference was statistically significant ( t=16.43, P<0.01). Conclusions:Sensorimotor training can improve the level of balance, cognitive function and reduce the risk of falls in elderly patients with schizophrenia.
ABSTRACT
Objective:To investigate the application effects of MOTOmed in stepped individualized rehabilitation intervention of older adult patients with post-stroke hemiplegia.Methods:A total of 130 older adult patients with post-stroke hemiplegia who received treatment in the Affiliated People's Hospital of Ningbo University from June 2019 to June 2021 were included in this study. They were randomly assigned to undergo either stepped individualized rehabilitation intervention with MOTOmed training system (observation group, n = 65) or routine rehabilitation intervention (control group, n = 65) for 1 month. Before and after intervention, the Fugl- Meyer Assessment score, Berg Balance Scale score, Functional Ambulation Category scale score, modified Ashworth scale score, and modified Barthel Index, Self-Perceived Burden Scale score, nerve growth factor, brain-derived neurotrophic factor and neurotrophin 3 levels were compared between the two groups. Results:After intervention, Fugl-Meyer Assessment and Berg Balance Scale scores in the observation groups were (75.48 ± 6.54) points and (48.55 ± 5.18) points, which were significantly greater than (72.55 ± 6.33) points and (46.50 ± 4.79) points in the control group ( t = 2.59, 2.34, both P < 0.05). Functional Ambulation Category scale score in the observation group was significantly higher than that in the control group [(3.22 ± 0.43) points vs. (3.05 ± 0.39) points, t = 2.36, P < 0.05). Modified Ashworth scale score in the observation group was significantly lower than that in the control group [(1.23 ± 0.24) points vs. (1.33 ± 0.26) points, t = 2.27, P < 0.05). Modified Barthel Index score in the observation group was significantly higher than that in the control group [(59.32 ± 5.18) points vs. (57.33 ± 4.92) points, t = 2.24, P < 0.05]. There was no significant difference in Self-Perceived Burden Scale score between the two groups ( t = 1.64, P > 0.05). Nerve growth factor level in the observation group was significantly higher than that in the control group [(12.93 ± 2.31) ng/L vs. (12.06 ± 2.29) ng/L, t = 2.15, P < 0.05]. There were no significant differences in brain-derived neurotrophic factor and neurotrophin 3 levels between the two groups ( t = 0.91, 1.25, both P > 0.05). Conclusion:The stepped individualized rehabilitation intervention with MOTOmed training system can greatly improve the limb function, balance ability, walking ability and self-care ability, reduce muscle tension, and increase nerve growth factor level in older adult patients with post-stroke hemiplegia, which are conducive to the rehabilitation and prognosis of post-stroke hemiplegia.

ABSTRACT
[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
Objective To study the effect of vibration training with adjusted frequency on changes in explosive force of lower limbs, balance and muscle function around ankle joints of patients with functional ankle instability (FAI), so as to provide an empirical basis for rehabilitation training of FAI patients in clinic. Methods Twenty-six FAI patients were randomly divided into the experimental group (n=14) and the control group (n=12). The experimental group received 8-week rehabilitation training with vibration intervention, while the control group only received 8-week rehabilitation training. Changes in maximum power, average power, maximum speed and average speed of the injured limb during vertical jump with single leg, changes in distances during long jump, changes in time during one-leg standing with eyes open and closed，changes in contract time (tc), relax time (tr) and displacement (Dm) of medial gastrocnemius (GM), lateral gastrocnemius (GL) and tibialis anterior (TA) muscles before and after training were measured and compared. Results In the experimental group, the maximum power and maximum speed of the injured limb during vertical jump with single leg, the distance during long jump with single leg and the time during one-leg standing with open and closed eyes were significantly improved, and the increase was higher than that of the control group. The increase of tc of all muscles in the experimental group was smaller than that of the control group, but tr and Dm did not show any regularity. Conclusions Vibration training with adjusted frequency can effectively improve the explosive force and balance ability of lower limbs of FAI patients, and promote the tc shortening of GL, GM and TA muscles, but whether vibration training with adjusted frequency can reduce muscle tension and promote muscle relaxation is still not clear.

ABSTRACT
The purpose of this study was to consider the validity of measuring the Star Excursion Balance Test (SEBT), which has been used as a measure of balance ability in athletes, for community-dwelling elderly people. To achieve this purpose, we examined the relationship between the existing balance ability measures, leg strength, and the SEBT. The subjects were 36 elderly people (mean age: 71.1 years). We used the SEBT, functional reach test (FRT), timed up-and-go test (TUG), and Mini-BESTest to evaluate balance ability and the 30-second chair-stand test (CS-30) to assess leg strength; we also assessed the 10-m walk time. The correlation coefficient with the SEBT was calculated. The significant level was 5%. A significant positive correlation was observed between the total score of Mini-BESTest and the SEBT reach distance in the anterior direction (r = 0.364, p < 0.05) and the posteromedial direction (r = 0.407, p < 0.05). A significant positive correlation was observed between anticipatory postural control and the SEBT reach distance in the anterior directions (r = 0.403, p < 0.05), and postural responses and SEBT reach distance in the posterolateral direction (r = 0.360, p < 0.05), which were subsystem category of Mini-BESTest. No significant correlation was found in the other items. The correlation with Mini-BESTest indicates that SEBT might be a valid tool to evaluate the dynamic balance ability of community-dwelling elderly people. However, their correlation coefficient is not high, suggesting that SEBT can evaluate elements different from Mini-BESTest.
ABSTRACT
PURPOSE: This study examined the effects of stretching and strengthening exercises on the pain, pelvic tilt (PT), functional disability, and balance of patients with chronic lower back pain (CLBP). METHODS: A total of 42 patients with CLBP were randomly divided randomly into either experimental group I (EG I, n=21), who received stretching exercise, or experimental group II (EG II, n=21), who received strengthening exercise. Both interventions were applied three times a week for eight weeks. Assessments were made with a visual analogue scale (VAS), PT, Oswestry disability index (ODI), and Berg's balance scale (BBS) before and after the eight weeks intervention period. A paired t-test was conducted to compare the within-group changes before and after the intervention. An independent t-test was used compare the between-group difference. The statistical significance level was set to α=0.05 for all variables. RESULTS: The EG I and II showed significant within-group changes in the VAS, PT, ODI, and BBS (p<0.05). The changes in VAS, PT, ODI, and BBS were similar regardless of the exercise form. CONCLUSION: In this study, the application of stretching and strengthening exercise for subjects who complain of CLBP was effective in changing the level of pain, PT, functional disability, and balance.

Objective:To explore the effect of Otago exercise on balance and balance confidence in the institutionalized elderly. Methods:From March to June, 2016, a total of 60 participants received Otago exercise for twelve weeks. They were assessed with Berg Balance Scale (BBS), Functional Reach Test (FRT), Four-Square Step Test (FSST) and Activities-Specific Balance Confidence Scale (ABC) before and after intervention. Results:After intervention, the scores of BBS, FRT and FSST significantly improved (t > 4.282, P < 0.001), and the number of people with the risk of falling significantly decreased (χ2 = 19.286, P < 0.001). Conclusion:Otago exercise could effectively improve the balance ability and balance confidence for the older adults in nursing home.
ABSTRACT
OBJECTIVE@#This paper used plantar pressure analysis equipment to discuss the plantar pressure distribution pattern and balance ability of patients with the knee joint injury under static standing.@*METHODS@#Zebris FDM-S plantar pressure analysis equipment was used to collect plantar pressure data from subjects with the knee joint injury and healthy control subjects. We compared the pressure values in each region of pelma, and then assessing the balance ability of the subjects based on the trajectory of the overall pressure center movement.@*RESULTS@#Compared with the healthy control group, patients with knee joint injury have a significantly lower pressure in the heel areas and a significantly higher pressure in the middle foot area. And the total pressure of the injured limb foot in the patient group is lower than that in the contralateral foot. In addition, there is a significant increase in the parameters of the balance ability index in the patient group.@*CONCLUSIONS@#The plantar pressure distribution pattern of patients with knee joint injury is different from that of normal people in static standing, and the balance ability is poor. Therefore, this method has a positive guiding significance in the evaluation and application of knee joint injury.

PURPOSE: The purpose of this study was to investigate the effects of combined training using proprioceptive neuromuscular facilitation (PNF) patterns and treadmills on the balance and walking ability of stroke patients. METHODS: Twenty-three stroke patients were randomized into a control group (n=11), receiving only treadmill training and an experimental group (n=12) receiving combined training. The use of both PNF exercise and treadmill were implemented in the combined training. Interventions were performed 5 times a week for 6 weeks. Balance ability was measured by a timed up and go (TUG) test. Walking ability was measured by a 10-meter walk test (10MWT) and a 6-minute walk test (6MWT). A paired t-test was used to compare differences between pre- and post-intervention and independent t-tests were used to compare between groups. RESULTS: Changes in TUG, 10MWT, and 6MWT before and after interventions were significantly different for both the experimental group and the control group (p < 0.05). In addition, within-group changes in the TUG, 10MWT, and 6MWT were more effective in the experimental group than in the control group (p < 0.05). CONCLUSION: Combined training using PNF techniques and treadmills may be useful in improving the balance and walking ability of stroke patients.
