Dual-Task Balance Training for Motor Skill Development among Children with Intelligence Quotient Discrepancy

The motor skills of people with mental disabilities are reportedly reduced compared with those of their peers. Therefore, any task incorporating both motor and cognitive skills was hypothesized to provide better motor recovery. The aim of this study is to find the effect of dual-task balance training (DTBT) on motor skill development in children of 6–13 years with intelligence quotient discrepancy (IQD) (score: 50–79). Overall, 30 individuals with mental disabilities aged 6–13 years having an IQ score of 50–79 were included. The participants were randomly divided into two groups that received dual-task training and standard balance training, respectively. IQ was measured with the Wechsler Intelligence Scale for Children-Revised, motor proficiency with the Bruininks–Oseretsky test, reaction time with COGNIBOARD, and balance with Functional Reach Test scores. Intervention was provided twice a week for 12 consecutive weeks. Participants in both groups showed higher test scores in all tests after the training program. Both training programs positively affected the motor performance of the participants. The DTBT was more effective in improving balance performance than the standard balance training. DTBT is a better tool than conventional balance training for improving motor skills and balance in children of 6–13 years with IQD (score: 50–79).

Proprioceptive Training versus Progressive Adaptive Physical Activity on Balance in Subjects with Sub-Acute Stroke

Background: Post-stroke, gait and balance are often affected increasing the risk of fall, social isolation and sedentary lifestyle. Proprioceptive training has always been a part of post-stroke rehabilitation which has seen to improve muscle strength, balance and gait. Progressive adaptive physical activity has also shown to improve balance, cardiovascular fitness and gait after stroke. This study aims to compare the effect of proprioceptive training and progressive adaptive physical activity on balance in sub-acute stroke subjects. Method: 30 subacute stroke subjects were randomly assigned to one of the two groups. Group A received proprioceptive training while Group B received progressive adaptive physical activity for 30 minutes, 3 times a week for eight weeks. Subjects in both the groups were assessed for balance using Berg Balance Scale and Functional Reach Test prior to the intervention and post-intervention. Result: Both the groups showed significant improvement in the pre to post FRT and BBS scores (p<0.001). Post-intervention, when compared between groups, Group A showed better improvement than Group B on the FRT scores (p<0.001) but no difference was seen in the BBS scores (p value>0.05). Conclusion: Proprioceptive training is found to be more effective than the progressive adaptive physical activity in improving balance among sub-acute stroke subjects. Key words: Stroke, Balance, proprioceptive training, progressive adaptive physical activity.

Modified Functional Reach Test: Upper-Body Kinematics and Muscular Activity in Chronic Stroke Survivors

Effective control of trunk muscles is fundamental to perform most daily activities. Stroke affects this ability also when sitting, and the Modified Functional Reach Test is a simple clinical method to evaluate sitting balance. We characterize the upper body kinematics and muscular activity during this test. Fifteen chronic stroke survivors performed twice, in separate sessions, three repetitions of the test in forward and lateral directions with their ipsilesional arm. We focused our analysis on muscles of the trunk and of the contralesional, not moving, arm. The bilateral activations of latissimi dorsi, trapezii transversalis and oblique externus abdominis were left/right asymmetric, for both test directions, except for the obliquus externus abdominis in the frontal reaching. Stroke survivors had difficulty deactivating the contralesional muscles at the end of each trial, especially the trapezii trasversalis in the lateral direction. The contralesional, non-moving arm had muscular activations modulated according to the movement phases of the moving arm. Repeating the task led to better performance in terms of reaching distance, supported by an increased activation of the trunk muscles. The reaching distance correlated negatively with the time-up-and-go test score.

Walking meditation versus balance training for improving balance abilities among older adults with history of fall: A randomized controlled trial

Objective To investigate improvement in balance abilities compared between walking meditation and balance training among older adults with history of fall. Interventions Walking meditation or mindfulness meditation whilst standing and moving ( n = 35) or balance training ( n = 33) 20–30 min/day, 5–7 days/week for 24 weeks was performed at home. Main outcomes The primary outcomes were dynamic balance abilities as assessed by Timed Up and Go test (TUGT), and static balance as assessed by Functional Reach Test (FRT) and Single Leg Stance Test (SLST). The secondary outcomes were quality of life as measured by the EuroQOL 5-dimensions 5-levels (EQ-5D-5L), and mental health as evaluated by the Thai Geriatric Mental Health Assessment Tool-15 (TGMHA-15). All outcomes were assessed at baseline, 6 months, and 9 months. Self-reported compliance, adverse events, and patient satisfaction were recorded at 6 and 9 months. Results The mean age was 69 years (range: 60–85). No significant difference was observed between groups for the 3 primary outcome measures. The mean difference (95% confidence interval) between groups was −0.48 (-1.40, 0.44) for TUGT, −1.11 (-3.66, 1.45) for FRT, and 0.82 (-5.03, 6.67) for SLST. The EQ-5D-5L and TGMHA-15 also showed no significant difference between groups. Most participants were in good compliance with the exercise protocol (48.3–68.0%), and no serious adverse events were reported. Conclusion Our results showed walking meditation to be comparable to balance training for improving balance abilities in older adults with history of fall. Walking meditation may be considered an alternative treatment for improving balance abilities in this patient population.

Clinical Tests for Predicting Fallers Among Ambulatory Patients with Amyotrophic Lateral Sclerosis: A Preliminary Cohort Study

Background: Few studies have examined falls and their predictors in patients with amyotrophic lateral sclerosis (ALS). Objective: The aim of this study was to survey fall incidence and to identify variables predicting the presence or absence of falls occurring within 3 months after discharge of patients with ALS from hospital. Methods: The following variables were evaluated in 14 patients with ALS: timed up and go test (TUG), functional reach test, 10-m comfortable gait speed, single-leg stance time, manual muscle test (MMT) scores for the lower limb, total modified Ashworth scale score for the lower limbs, fear of falling, and pull test score. The primary outcome variable was the occurrence of a fall within 3 months after discharge. The fall rate was calculated based on fall record forms. The specific circumstances of each fall were also recorded. Univariate and multiple regression analyses were used to identify fall predictors. Results: Seven of the 14 ALS patients (50%) experienced a fall within 3 months. Five fallers reported experiencing a fall that had caused injury, and three reported experiencing a fall that had required a hospital visit. Univariate logistic regression analysis identified TUG time, gait speed and MMT of the ankle dorsiflexors as factors associated with falls (p = 0.02–0.04). Multiple linear regression analysis of fall numbers identified age and TUG time as predictor models (p = 0.03). Conclusion: TUG time and MMT of ankle dorsiflexors may help predict falls in ALS patients. Validation studies in larger cohorts are needed.

Feasibility of the basic movements of Azeri dance in the balance and posture of a person with Parkinson's disease: ABA single-subject design

Background/aims Basic movements of Azeri dance as an intervention may have an impact on the physical and mental status of people with Parkinson's disease. The aim of this study was to assess the feasibility and efficacy of basic movements of Azeri dance on the balance and static posture of a person with Parkinson's disease. The effects of basic movements of Azeri dance on quality of life, quality of sleep and the performance in activities of daily living were reported before and after the intervention. Methods In this single-subject experimental ABA design, a 64-year-old man with a 4-year history of Parkinson's disease was selected. The outcome measures consisted of the Functional Reach Test, Timed Up and Go Test, qualitative static posture analysis, Short Form Health Survey, Modified Barthel Index and Pittsburgh Sleep Quality Index. Results An increasing trend in balance from the initial baseline stage through to the end of the intervention stage was found. Static posture analysis showed that the patient's posture improved qualitatively. His quality of life score changed after the intervention; however, his sleep quality and activites of daily living scores did not change. Conclusions Basic movements of Azeri dance are useful in the rehabilitation of patients with Parkinson's disease who have balance issues and postural instability, but further research is warranted.

Reliability of stair-climbing speed in two cohorts of older adults

Background/Aims The ability to climb stairs is an important prerequisite for activities of daily living and social participation in older adults, and is therefore an important part of rehabilitation. However, there is no consensus on how to measure stair-climbing ability. The aim of this study was to investigate the test–retest reliability of the measurement of stair-climbing speed (steps per second) as a parameter for functional ability in older adults. Methods A total of 57 participants who were in hospital and 56 participants who were community-dwelling and did not have any limitations in activities in daily living, all aged 60 years and over, ascended and descended a set of 13 stairs twice. The halfway point of the staircase was marked in order to split the time required for both the ascending and the descending actions. Additional measurements consisted of the Functional Reach Test, the Timed Up and Go Test, walking ability using the GAITRite walkway system and the isometric strength of four muscle groups of the lower extremities using a handheld dynamometer. Results Test–retest reliability of the first and second half of the stair-climbing for both ascending and descending showed excellent results for the group of hospitalised participants (intraclass correlation coefficient, [ICC] 0.87, 95% confidence interval [CI] 0.79–0.93 to 0.94, 95% CI 0.9 – 0.97 for comparison of first vs second half of stair climbing; ICC 0.9, 95% CI 0.83-0.94 to ICC 0.95, 95% CI 0.92–0.97 for comparing first vs second measurement)) and moderate to excellent results for the group of community-dwelling participants with no limitations (ICC 0.58, 95% CI 0.37–0.73 to ICC 0.76, 95% 95% CI 0.63-0.85 for comparison of first vs second half of stair climbing; ICC 0.82, 95% CI 0.71-0.89 to 0.92, 95% CI 0.87–0.95 for comparing first vs second measurement). As expected, hospitalised participants took significantly longer descending than ascending stairs (t(56)=6.98, P<0.001, d=0.93). A general and significant trend of increasing speed while descending could be observed in both groups (performing paired sample t-tests). Conclusions The results indicate that stair-climbing speed is not constant and that different patterns exist in older adults who have no limitations and in those who are hospitalised. The use of stair-climbing speed as an assessment tool should include both stair ascent and descent, because differences in these speeds seem to be indicators of stair-climbing ability.

Immediate Effect of Kinesiology Tape on Functionality, Static and Dynamic Balance, Exercise Capacity and Posture in Users of High-Heeled Shoes

Background: Using high-heeled shoes in daily life affects the stability of walking, body posture, and functionality. So, the present study was aimed to determine the immediate effect of Kinesio-taping (KT) on functionality, static and dynamic balance, exercise capacity, posture in young women using high-heeled shoes. Methods: Thirty-seven females who were used high-heeled shoes with a mean age of 20.32{plus minus}1.37 years were divided into two groups: control (n:20) and study group(n:17). The study group's both limbs were taped medially, laterally, and dorsally with KT; no application was made to the control group. Balance [Techno Body Postural Line], functionality [vertical jump and functional reach test], exercise capacity [6-min walk test], human body posture [New York Posture Rating Chart] was assessed. Results: Use of high-heeled shoes was 8(7-9) hours/day, 5(3-5) days/week, 3(2-6.5) years in the study group versus 6(6-8) hours/day, 4(2.5-5.75) days/week for 4(2.5-5.75) years in the control group. Statistical significance in functional reach distance (cm) was found within the control (p:0.010) and study groups (p:0.005) but not between the groups (p˃0.05). Stabilometric mono pedal right foot elips area (mm2; p:0.006) and perimeter (mm;p:0.009); left foot elips area (mm2;p:0.016), perimeter (mm;p:0.023) and front/backward standard deviation (p:0.018); dynamic balance area gap percentage (%; p:0.030) were significant within the study group. Posture, vertical jump distance, exercise capacity, stabilometric test results, bipedal closed-eye&opened eye results were similar within and between the groups (p˃0.05). Conclusions: Kinesio-taping has no immediate effect on exercise capacity, vertical jump function, posture, and bipedal static balance but can modulate the functional reach function, static mono pedal leg balance, and dynamic equilibrium. Further studies are recommended to investigate the additive effect of KT with high heels and after 45 minutes, 24 hours and 72 hours.

Effects of robot-assisted trunk control training on trunk control ability and balance in patients with stroke: A randomized controlled trial

BACKGROUND: Trunk control ability is an important component of functional independence after the onset of stroke. Recently, it has been reported that robot-assisted functional training is effective for stroke patients. However, most studies on robot-assisted training have been conducted on upper and lower extremities. OBJECTIVE: The purpose of this study was to evaluate the effects of robot-assisted trunk control training on trunk postural control and balance ability in stroke patients. METHODS: Forty participants with hemiparetic stroke were recruited and randomly divided into two groups: the RT (robot-assisted trunk control training) group (n= 20) and the control group (n= 20). All participants underwent 40 sessions of conventional trunk stabilization training based on the Bobath concept (for 30 minutes, five-times per week for 8 weeks). After to each training session, 15 minutes of robotassisted trunk control training was given in the RT group, whereas the control group received stretching exercise for the same amount of time. Robot-assisted trunk control training was conducted in three programs: sitting balance, sit-to stand, and standing balance using a robot system specially designed to improve trunk control ability. To measure trunk postural control ability, trunk impairment scale (TIS) was used. Center of pressure (COP) distance, limits of stability (LOS), Berg Balance Scale (BBS) and functional reach test (FRT) were used to analyze balance abilities. RESULTS: In TIS, COP distance, LOS, BBS and FRT, there were significant improvements in both groups after intervention. More significant changes were shown in the RT group than the control group (p< 0.05). CONCLUSIONS: Our findings indicate that robot-assisted trunk control training is beneficial and effective to improve trunk postural control and balance ability in stroke patients. Therefore robot-assisted training may be suggested as an effective intervention to improve trunk control ability in patients with stroke.

A modified digital functional reach test device using an ultrasonic sensor for balance assessment: A test of validity and reliability

Study aim: Evaluation of dynamic balance is inferred to be compulsory for fall prevention in the elderly. Therefore, this study aimed to develop a modified digital functional reach test device using an ultrasonic sensor for balance assessment and to test validity and reliability of the newly developed tool to qualify psychometric properties. Material and methods: This study was a cross-sectional study of a convenient sample including 50 participants both males and females. Mean age of the participants was 51.20 ± 19.30 years. Reliability of the newly developed device was analysed using the intraclass correlation coefficient (ICC) and standard error of measurement (SEM). The criterion validity was also investigated using a yardstick mounted on the wall at a level of shoulder together with the MaxTraq® 2D motion analysis software. The modified digital functional reach test device using an ultrasonic sensor was correlated with the conventional FRT and the MaxTraq® 2D motion analysis. Results: The results presented that test-retest reliability of the modified digital functional reach test device was good reliability (ICC = 0.76) and low standard error of measurement (1.41) was found for test-retest reliability. The degree of agreement between the modified device, the conventional FRT, and the MaxTraq® 2D motion analysis was high (r = 0.71 and 0.77 respectively). Conclusions: The findings suggested that the modified digital functional reach test device using an ultrasonic sensor was a valid and reliable instrument for fall risk screening towards functional reach distance.
