Balance performance, falls-efficacy and social participation in patients with type 2 diabetes mellitus with and without vestibular dysfunction. PeerJ 2024; 12:e17287. [PMID: 38766481 PMCID: PMC11102735 DOI: 10.7717/peerj.17287] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2023] [Accepted: 04/02/2024] [Indexed: 05/22/2024] Open
Abstract
Background The performance of balance is an important factor to perform activities. The complications of type 2 diabetes mellitus (T2DM), especially vestibular dysfunction (VD), could decrease balance performance and falls-efficacy (FE) which consequently impacts social participation and quality of life (QoL). Purpose This study aimed to compare balance performance, FE, social participation and QoL between individuals with T2DM with and without VD. Methods The participants comprised 161 T2DM with VD and 161 without VD. Three clinical tests used for confirming VD included the Head Impulse Test (HIT), the Dix Hallpike Test (DHT) and the Supine Roll Test (SRT). The scores of static and dynamic balances, FE, social participation and QoL were compared between groups. Results The balance performance, FE, social participation and QoL were lower in the group with VD. The number of patients who had severe social restriction was higher in T2DM with VD than without VD (58.4% vs 48.4%). Moreover, all domains of QoL (physical, psychological, social relationships and environmental) were lower in T2DM with VD than without VD. Conclusion The presence of VD in T2DM patients was associated with decreased physical balance performances and increased social and QoL disengagement. Comprehensive management related to balance and FE, as well as the monitoring to support social participation and QoL, should be emphasized in patients with T2DM with VD.

Effects of anodal tDCS on resting state eeg power and motor function in acute stroke: a randomized controlled trial. J Neuroeng Rehabil 2024; 21:6. [PMID: 38172973 PMCID: PMC10765911 DOI: 10.1186/s12984-023-01300-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Accepted: 12/21/2023] [Indexed: 01/05/2024] Open
Abstract
BACKGROUND Anodal transcranial direct current stimulation (tDCS) is a beneficial adjunctive tool in stroke rehabilitation. However, only a few studies have investigated its effects on acute stroke and recruited only individuals with mild motor deficits. This study investigated the effect of five consecutive sessions of anodal tDCS and conventional physical therapy on brain activity and motor outcomes in individuals with acute stroke, with low and high motor impairments. METHODS Thirty participants were recruited and randomly allocated to either the anodal or sham tDCS group. Five consecutive sessions of tDCS (1.5 mA anodal or sham tDCS for 20 min) were administered, followed by conventional physical therapy. Electroencephalography (EEG), Fugl-Meyer Motor Assessment (FMA), and Wolf Motor Function Test (WMFT) were performed at pre-, post-intervention (day 5), and 1-month follow-up. Sub-analyses were performed on participants with low and high motor impairments. The relationship between EEG power and changes in motor functions was assessed. RESULTS Linear regression showed a significant positive correlation between beta bands and the FMA score in the anodal group. Elevated high frequency bands (alpha and beta) were observed at post-intervention and follow-up in all areas of both hemispheres in the anodal group, while only in the posterior area of the non-lesioned hemisphere in the sham group; however, such elevation induced by tDCS was not greater than sham. Lower limb function assessed by FMA was improved in the anodal group compared with the sham group at post-intervention and follow-up only in those with low motor impairment. For the upper limb outcomes, no difference between groups was found. CONCLUSIONS Five consecutive days of anodal tDCS and physical therapy in acute stroke did not result in a superior improvement of beta bands that commonly related to stroke recovery over sham, but improved lower extremity functions with a post-effect at 1-month follow-up in low motor impairment participants. The increase of beta bands in the lesioned brain in the anodal group was associated with improvement in lower limb function. TRIAL REGISTRATION NCT04578080, date of first registration 10/01/2020.

Non-linear dose response effect of cathodal transcranial direct current stimulation on muscle strength in young healthy adults: a randomized controlled study. BMC Sports Sci Med Rehabil 2023; 15:10. [PMID: 36717894 PMCID: PMC9887803 DOI: 10.1186/s13102-023-00621-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2022] [Accepted: 01/25/2023] [Indexed: 01/31/2023]
Abstract
BACKGROUND Transcranial direct current stimulation (tDCS) is a technique that modulates brain excitability in humans. Increasing the stimulation intensity or duration within certain limits could enhance tDCS efficacy with a polarity-dependent effect; anodal stimulation increases cortical excitability, whereas cathodal stimulation decreases excitability. However, recent studies have reported a non-linear effect of cathodal tDCS on neuronal excitability in humans, and there is no conclusive result regarding the effect of cathodal tDCS on muscle performance. METHODS Our study aimed to investigate the immediate effects of different intensities (i.e., 1, 1.5, and 2 mA and sham tDCS) of cathodal tDCS on muscle strength in healthy participants. All participants [mean age 23.17 (3.90) years] were recruited and randomly allocated into four groups (1, 1.5, and 2 mA cathodal tDCS and sham tDCS). Muscle strength in bilateral upper and lower extremities was measured before and immediately after tDCS using a handheld dynamometer. RESULTS Our results showed that cathodal tDCS at 1 and 1.5 mA reduced muscle strength bilaterally in upper and lower extremity muscles, whereas stimulation at 2 mA tended to increase muscle strength on the dominant limb. CONCLUSION These findings support the non-linear effects of cathodal tDCS on muscle strength, which should be considered for the clinical use of tDCS in motor rehabilitation.

Quantitative gait analysis in mild cognitive impairment, dementia, and cognitively intact individuals: a cross-sectional case-control study. BMC Geriatr 2022; 22:767. [PMID: 36151524 PMCID: PMC9502583 DOI: 10.1186/s12877-022-03405-9] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2021] [Accepted: 08/23/2022] [Indexed: 11/10/2022] Open
Abstract
Background Cognitive age-related decline is linked to dementia development and gait has been proposed to measure the change in brain function. This study aimed to investigate if spatiotemporal gait variables could be used to differentiate between the three cognitive status groups. Methods Ninety-three older adults were screened and classified into three groups; mild cognitive impairment (MCI) (n = 32), dementia (n = 31), and a cognitively intact (n = 30). Spatiotemporal gait variables were assessed under single- and dual-tasks using an objective platform system. Effects of cognitive status and walking task were analyzed using a two-way ANCOVA. Sub-comparisons for between- and within-group were performed by one-way ANCOVA and Paired t-tests. Area Under the Curve (AUC) of Receiver Operating Characteristics (ROC) was used to discriminate between three groups on gait variables. Results There were significant effects (P < 0.05) of cognitive status during both single and dual-task walking in several variables between the MCI and dementia and between dementia and cognitively intact groups, while no difference was seen between the MCI and cognitively intact groups. A large differentiation effect between the groups was found for step length, stride length, and gait speed during both conditions of walking. Conclusions Spatiotemporal gait variables showed discriminative ability between dementia and cognitively intact groups in both single and dual-tasks. This suggests that gait could potentially be used as a clinical differentiation marker for individuals with cognitive problems.

Abstract
OBJECTIVE Transcranial direct current stimulation (tDCS) has shown positive results in neurorehabilitation. However, there is limited evidence on its use in acute stroke, and unclear evidence regarding the best tDCS montage (anodal-, cathodal-, or dualtDCS) for stroke recovery. This study investigated the effects of these montages combined with physical therapy on haemodynamic response and motor performance. METHODS Eighty-two eligible acute stroke participants were allocated randomly into anodal, cathodal, dual, and sham groups. They received 5 consecutive sessions of tDCS combined with physical therapy for 5 days. Cerebral mean blood flow velocity (MFV) and motor outcomes were assessed pre- and post-intervention and at a 1-month follow-up. RESULTS None of the groups showed significant changes in the MFV in the lesioned or non-lesioned hemispheres immediately post- intervention or at a 1-month follow-up. For motor performance, all outcomes improved over time for all groups; between-group comparisons showed that the dual-tDCS group had significantly greater improvement than the other groups for most of the lower-limb performance measures. All 5-day tDCS montages were safe. CONCLUSION MFV was not modulated following active or sham groups. However, dual-tDCS was more efficient in improving motor performance than other groups, especially for lower-limb performance, with after-effects lasting at least 1 month.

Abstract
OBJECTIVE To examine the effect of a progressive bridging exercise on force, time, and pressure during the extension phase of sit-to-stand, and on sit-to-stand ability in individuals with stroke. DESIGN A single-blinded randomised controlled trial. SETTING Hospital. PARTICIPANTS Forty-eight individuals with acute ischemic stroke, not at brainstem and cerebellum, randomly allocated to the intervention (n = 24) and control (n = 24) groups. Five participants dropped out during the 2-month follow-up, but they were in the intention-to-treat analysis. INTERVENTIONS The intervention group undertook a 45-min conventional physiotherapy and a 30-min progressive bridging exercise. The control group received only the conventional exercise. MAIN MEASURES Peak vertical ground reaction force, time to peak force, peak foot pressure, and regional peak foot pressure during the extension phase of sit-to-stand, and sitting-to-standing item of the Motor Assessment Scale were assessed before training, after 4-week training, and 2-month follow-up. RESULTS The intervention group showed significantly (p < 0.001) less difference in peak vertical ground reaction force between feet during the extension phase of sit-to-stand than the control after 4-week training (mean ± standard deviation; intervention, 5.38 ± 3.99; control, 17.1 ± 10.3) and 2-month follow-up (intervention, 6.79 ± 3.84; control, 17.5 ± 9.89), and demonstrated significantly (p < 0.001) higher score in sit-to-stand than the control after training [mean (interquartile range); intervention, 5 (2-5); control, 2 (1-2)] and follow-up [intervention, 2 (2-5); control, 2 (1-2)]. Both groups demonstrated peak foot pressure on the medial and lateral heels, metatarsals, and hallux regions. CONCLUSION Progressive bridging exercise improved symmetrical weight bearing during the extension phase of sit-to-stand, consequently enhanced sit-to-stand ability in individuals with stroke.

Abstract
Objective To compare the effect of motor imagery combined with structured progressive circuit class therapy vs health education combined with structured progressive circuit class therapy on dynamic balance, endurance, and functional mobility in post-stroke individuals. Design Randomized controlled trial. Methods A total of 40 post-stroke individuals were randomly assigned to experimental and control groups. The experimental group was trained using motor imagery combined with structured progressive circuit class therapy, while the control group received health education combined with structured progressive circuit class therapy, 3 times a week for 4 weeks with an overall of 12 sessions. Outcomes included the step test for affected and unaffected limbs, the 6-Minute Walk Test, and the Timed Up and Go test. Assessments were performed at baseline, 2 weeks, and 4 weeks after the intervention Results There were significant effects (p < 0.05) of: group on the step test for unaffected limb; of time on all outcomes; and of their interaction effect on the step test for affected limb, 6-Minute Walk Test, and Timed Up and Go test. Inter-group comparison showed significant differences (p < 0.05) in the step test for unaffected limb at 2 weeks after the intervention. At 4 weeks after the intervention, significant differences (p < 0.05) were found in the step test for affected and unaffected limbs and in the Timed Up and Go test. Conclusion Motor imagery combined with structured progressive circuit class therapy was more effective on the step test, 6-Minute Walk Test, and Timed Up and Go test than training with structured progressive circuit class therapy alone. This suggest that that motor imagery should be incorporated into training programmes for restoring dynamic balance, endurance, and functional mobility in post-stroke individuals.

Abstract
PURPOSE This study aimed to determine the effects of home-based dual-hemispheric transcranial direct current stimulation (dual-tDCS) combined with exercise on motor performance in patients with chronic stroke. MATERIALS AND METHODS We allocated 24 participants to the active or sham group. They completed 1-h home-based exercise after 20-min dual-tDCS at 2-mA, thrice a week for 4 weeks. The patients were assessed using the Fugl-Meyer Assessment (FMA), Wolf Motor Function Test, Timed Up and Go test, Five Times Sit-to-Stand Test, Six-meter Walk Test, and muscle strength assessment. RESULTS Compared with the sham group, the active group showed improved FMA scores, which were sustained for at least 1 month. There was no between-group difference in the outcomes of the functional tasks. CONCLUSION Home-based dual-tDCS could facilitate motor recovery in patients with chronic stroke with its effect lasting for at least 1 month. However, its effects on functional tasks remain unclear. tDCS is safe and easy for home-based self-administration for patients who can use their paretic arms. This could benefit patients without access to health care centres or in situations requiring physical distancing. This home-based tDCS combined with exercise has the potential to be incorporated into telemedicine in stroke rehabilitation.IMPLICATIONS FOR REHABILITATIONTwelve sessions of home-based dual-tDCS combined with exercises (3 days/week for 4 weeks) facilitated upper and lower limb motor recovery in patients with chronic stroke compared with exercise alone, with a post-effect for at least 1 month.Home-based tDCS could be safe and easily self-administrable by patients who can use their paretic arms.This intervention could be beneficial for patients living in the community without easy access to a health care centre or in situations where physical distancing is required.

Abstract
Structured Progressive Circuit Class Therapy (SPCCT) was developed based on task-oriented therapy, providing benefits to patients’ motivation and motor function. Training with Motor Imagery (MI) alone can improve gait performance in stroke survivors, but a greater effect may be observed when combined with SPCCT. Health education (HE) is a basic component of stroke rehabilitation and can reduce depression and emotional distress. Thus, this study aimed to investigate the effect of MI with SPCCT against HE with SPCCT on gait in stroke survivors. Two hundred and ninety stroke survivors from 3 hospitals in Yangon, Myanmar enrolled in the study. Of these, 40 stroke survivors who passed the selection criteria were randomized into an experimental (n = 20) or control (n = 20) group. The experimental group received MI training whereas the control group received HE for 25 minutes prior to having the same 65 minutes SPCCT program, with both groups receiving training 3 times a week over 4 weeks. Temporo-spatial gait variables and lower limb muscle strength of the affected side were assessed at baseline, 2 weeks, and 4 weeks after intervention. After 4 weeks of training, the experimental group showed greater improvement than the control group in all temporospatial gait variables, except for the unaffected step length and step time symmetry which showed no difference. In addition, greater improvements of the affected hip flexor and knee extensor muscle strength were found in the experimental group. In conclusion, a combination of MI with SPCCT provided a greater therapeutic effect on gait and lower limb muscle strengths in stroke survivors.

Abstract
PURPOSE To use structural equation model (SEM) to explain falls at home in individuals with chronic stroke, based on the International Classification of Functioning, Disability and Health (ICF). MATERIALS AND METHODS A cross sectional observation study was conducted in home-dwelling individuals with chronic stroke (N = 236; 148 non-fallers, 88 fallers). Participants were assessed; structural impairments using Modified Ashworth Scale, Fugl-Meyer Assessment upper (FMA-UE), lower (FMA-LE), and sensory function, ankle plantarflexor strength; activity limitations using Timed Up and Go Test, Step Test, Berg Balance Scale, Barthel Index (BI); participation restrictions using Stroke Impact Scale-participation (SIS-P); and contextual factors using home hazard environments, home safety surroundings, risk behaviors, and Fall-related Self Efficacy. The measurement model was analyzed by confirmatory factor analysis. The SEM was conducted to analyze a structural model of falls at home. RESULTS FMA-UE was significantly (p<0.01) associated with FMA-LE, combining as one variable in the structural impairments. In the measurement model, variables were fit to their domains, except variables of contextual factors, but the ICF domains did not correspond to disability. A structural model of falls at home demonstrated a significant (p<0.01) direct path of contextual factors and activity limitations with falls at home. The structural impairments showed a significant (p<0.01) direct path with activity limitations. All variables, except BI, SIS-P and risk behaviors, related to their domains in the structural model. CONCLUSIONS A structural model of falls at home proposes contextual factors being the strongest association with falls at home that home hazard environments seem the most influence in its domain. The activity limitations presented by balance ability are directed to falls at home. The structural impairments are associated with falls at home through activity limitations. Home assessment to decrease home hazard environments is suggested to prevent falls at home for individuals with chronic stroke.

Abstract
Fear of falling (FoF) is known to affect the physical activities and quality of life of older adults with type 2 diabetes mellitus (DM). Many complications of DM, especially ones distressing lower extremity (LE), could lead to increased fall risk and FoF. This study aimed to explore the relationship between FoF, LE muscle strength, and physical performance in older adults without diabetes mellitus (ONDM) and with DM (ODM) with varying degrees of balance impairment. The participants comprised 20 ONDM and 110 ODM. The ODM was grouped by the number of failed performances of the modified clinical test of sensory interaction and balance (mCTSIB). The scores of FoF, balance performance of mCTSIB, physical performance of TUG, and LE muscle strength were compared between groups. The results showed that FoF was present in 30% and 60% of the ONDM and ODM, respectively. Forty percent of the ODM failed one condition of the mCTSIB, while 18% and 16% failed two and three conditions, respectively. As the number of failed performances on the mCTSIB increased, the proportions of participants with FoF significantly increased. The psychosocial domain of FoF, LE muscle strength, and TUG score was significantly different between groups and more affected in the ODM with a greater number of failed performances on the mCTSIB. In conclusion, the mCTSIB can differentiate the varying degrees of balance impairment among ODM. FoF, LE muscle strength, and physical performance are more affected as the degree of balance impairment increases. Comprehensive management related to balance and falls in the ODM should include a regular evaluation and monitoring of standing balance, LE muscle strength, physical performance, and FoF.

Abstract
Objective To compare balance performance and lower limb muscle strength between older adults with type 2 diabetes mellitus (DM), with and without sensory impairments and non-DM groups. Influence of a number of sensory impairments, and muscle strength on balance performance were explored. Methods Ninety-two older adults with and without type 2 DM, were examined relative to visual function with the Snellen chart, Melbourne Edge test, and Howard-Dolman test, vestibular function with the modified Romberg test, proprioception of the big toe, and diabetic peripheral neuropathy with the Michigan Neuropathy Screening Instrument. Balance performances were evaluated with the Romberg test, Functional Reach Test (FRT), and Timed Up and Go test (TUG). Strength of knee and ankle muscles was measured. Results FRT of type 2 DM groups with at least two sensory impairments, was lower than the non-DM group (p<0.05). TUG of all DM groups, was worse than the non-DM group (p<0.01). Lower limb muscle strength of type 2 DM groups with two and three sensory impairments, was weaker than non-DM group (p<0.05). Regression analysis showed that type 2 DM with three sensory impairments, ankle dorsiflexors strength, and age were influential predictors of TUG. Conclusion There were significant differences, of muscle strength and balance performance among groups. Poorer balance and reduced lower limb strength were marked in older adults with type 2 DM, even ones without sensory impairment. Muscle weakness seemed to progress, from the distal part of lower limbs. A greater number of sensory impairments, weaker dorsiflexors, and advanced age influenced balance performance.

Abstract
BACKGROUND AND PURPOSE Spatio-temporal parameters are commonly used in gait assessment. Advanced tools provide valid and reliable data, considered very effective for physiotherapy intervention. However, these tools may be limited in clinical usage caused by complicated applicability, inaccessibility, and high cost. Therefore, a video-based system is an alternative choice that is easy and affordable for the clinical setting. The purpose of the study was to evaluate the concurrent validity of the video-based system against the validated instrumented gait system (Force Distribution Measurement [FDM]) on the spatio-temporal gait parameters in individuals with stroke. In addition, the intratester reliability of a novice tester was determined. METHODS Twenty individuals with stroke participated in the study. Gait was captured by the video-based and FDM systems simultaneously to measure the degree of concurrent validity. Parameters composed of the affected and unaffected step lengths (cm) and step time (s), stride length (cm), gait velocity (m/s), and cadence (steps/min). Pearson correlation coefficient, paired t test, and intraclass correlation coefficient (ICC) were used to determine the concurrent validity, the difference of the data, and intratester reliability. RESULTS All spatio-temporal gait parameters showed excellent degrees of correlation (rp = .94 to.99, p <.001) between the video-based and FDM systems. No significant difference in all parameters was found between the two systems. Excellent intratester reliability (ICC3,1 = 0.91 to 0.99, p < .001) of all gait parameters were found in a novice tester. CONCLUSION The video-based system was valid and reliable for a novice tester to measure the spatio-temporal gait parameters in individuals with stroke.

Abstract
Background. Understanding the relationship between movement quality (impairment) and performance (activity) in poststroke patients is important for rehabilitation intervention studies. This has led to an interest in kinematic characterization of upper limb motor impairment. Since instrumented motion analysis is not readily clinically available, observational kinematics may be a viable alternative. Objective. To determine if upper limb movement quality during a reach-to-grasp task identified by observation could be used to describe the relationship between motor impairments and the time to perform functional tasks. Methods. Cross-sectional, secondary analysis of baseline data from 141 participants with stroke, age 18 to 85 years, who participated in a multicenter randomized controlled trial. Clinical assessment of movement quality using the Reaching Performance Scale for Stroke (RPSS-Close and Far targets) and of performance (activity) from the Wolf Motor Function Test (WMFT-7 items) was assessed. The degree to which RPSS component scores explained scores on WMFT items was determined by multivariable regression. Results. Clinically significant decreases (>2 seconds) in performance time for some of the more complex WMFT tasks involving prehension were predicted from RPSS-Close and Far target components. Trunk compensatory movements did not predict either increases or decreases in performance time for the WMFT tasks evaluated. Overall, the strength of the regression models was low. Conclusions. In lieu of kinematic analysis, observational clinical movement analysis may be a valid and accessible method to determine relationships between motor impairment, compensations and upper limb function in poststroke patients. Specific relationships are unlikely to generalize to all tasks due to kinematic redundancy and task specificity.

Abstract
PURPOSE The aim of the study was to investigate the influence of sound on standing postural control in the elderly with and without knee osteoarthritis (knee-OA). METHODS Twenty-six elderly with knee-OA and 26 elderly without knee-OA who matched the age and height participated in this study. The standing postural stability was assessed by the 3D motion analysis system. Four testing conditions of the combination of sound (no sound and white noise sound) and surface (firm and soft surfaces) were tested three times with eyes closed for 30 sec. Postural stability variables included the standard deviation and velocity of the centre of pressure, the total body centre of mass, and centre of the head along the antero-posterior (AP) and medio-lateral (ML) directions. RESULTS Statistical significant reductions of all variables along ML direction were found in the elderly without a knee-OA in the presence of sound during standing on a firm surface. No significant effect of sound was found in the elderly with the knee-OA during standing on a firm surface. In the standing on a soft surface, both groups demonstrated no significant effect of sound on all postural stability variables. CONCLUSIONS Application of sound improved the standing postural stability in the frontal plane for the elderly without knee-OA. However, the effect of sound was limited in standing on a soft surface for both elderly with and without knee-OA.

Abstract
Objective To describe perceived participation among persons with first stroke and to identify the predictors based on the International Classification of Functioning, Disability and Health (ICF) concept of participation after stroke. Methods A total of 121 participants completed 4 questionnaires: the Impact on Participation and Autonomy (IPA), Personal Resource Questionnaire (PRQ2000), Hospital Anxiety and Depression Scale (HADS), and personal history. They were evaluated for their balance, motor function, functional and walking ability. Results The majority of participants perceived participation restriction in family role as poor to very poor. The best predictors of participation included social support, walking and balance, functional ability, number of secondary health problems and affected side, account for 66.6% of the variances in participation. Conclusion The study highlights the importance of social support, walking and balance performance, functional ability in daily living, and number of secondary health problems after stroke. These factors that facilitate participation after stroke should be addressed by health personnel during rehabilitation.

Effects of physical, virtual reality-based, and brain exercise on physical, cognition, and preference in older persons: a randomized controlled trial. Eur Rev Aging Phys Act 2018; 15:10. [PMID: 30305852 PMCID: PMC6169073 DOI: 10.1186/s11556-018-0199-5] [Citation(s) in RCA: 36] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2018] [Accepted: 09/24/2018] [Indexed: 12/25/2022] Open
Abstract
Background Physical exercise (PE), virtual reality-based exercise (VRE), and brain exercise (BE) can influence physical and cognitive conditions in older persons. However, it is not known which of the three types of exercises provide the best effects on physical and cognitive status, and which exercise is preferred by older persons. This study compared the effects of PE, VRE, and BE on balance, muscle strength, cognition, and fall concern. In addition, exercise effort perception and contentment in older persons was evaluated. Methods Eighty-four older persons (n = 84) were randomly selected for PE, VRE, BE, and control groups. The exercise groups received 8-week training, whereas the control group did not. Balance was assessed by Berg Balance Scale (BBS) and Timed Up and Go test (TUG), muscle strength by 5 Times Sit to Stand (5TSTS) and left and right hand grip strength (HGS), cognition by Montreal Cognitive Assessment (MoCA) and Timed Up and Go test Cognition (TUG-cog), fall concern by Fall Efficacy Scale International (FES-I), exercise effort perception by Borg category ratio scale (Borg CR-10), and exercise contentment by a questionnaire. Results After exercise, PE significantly enhanced TUG and 5TSTS to a greater extent than VRE (TUG; p = 0.004, 5TSTS; p = 0.027) and BE (TUG; p = 0,012, 5TSTS; p < 0.001). VRE significantly improved MoCA (p < 0.001) and FES-I (p = 0.036) compared to PE, and 5TSTS (p < 0.001) and FES-I (p = 0.011) were improved relative to BE. MoCA was significantly enhanced by BE compared to PE (p < 0.001) and both MoCA and TUG-cog were improved compared to VRE (p = 0.04). PE and VRE significantly (p < 0.001) increased Borg CR-10 in all exercise sessions, whereas BE showed a significant improvement (p < 0.001) in the first 4 sessions. Participants had a significantly greater satisfaction with BE than controls (p = 0.006), and enjoyed VRE and BE more than PE (p < 0.001). Subjects in all exercise groups exhibited benefits compared to the control group (p < 0.001). Conclusions PE provided the best results in physical tests, VRE produced measurable improvements in physical and cognition scores, while BE enhanced cognition ability in older persons. Older persons preferred VRE and BE compared to PE. Both exercises are suggested to older persons to improve physical and cognitive conditions.

Abstract
Anodal stimulation increases cortical excitably, whereas cathodal stimulation decreases cortical excitability. Dual transcranial direct current stimulation (tDCS; anodal over the lesioned hemisphere, cathodal over the non-lesioned hemisphere) was found to enhance motor learning. The corresponding tDCS-induced changes were reported to reduce the inhibition exerted by the unaffected hemisphere on the affected hemisphere and restore the normal balance of the interhemispheric inhibition. Most studies were devoted to the possible modification of upper-limb motor function after tDCS; however, almost no study has demonstrated its effects on lower-limb function and gait, which are also commonly disordered in stroke patients with motor deficits. In this randomized sham-controlled crossover study, we included 19 patients with sub-acute stroke. Participants were randomly allocated to receive real or sham dual-tDCS followed by conventional physical therapy with an intervention interval of at least 1 week. Dual-tDCS was applied over the lower-limb M1 at 2-mA intensity for 20min. Lower-limb performance was assessed by the Timed Up and Go (TUG) and Five-Times-Sit-To-Stand (FTSTS) tests and muscle strength was assessed by peak knee torque of extension. We found a significant increase in time to perform the FTSST for the real group, with improvements significantly greater than for the sham group; the TUG score was significantly increased but not higher than for the sham group. An after-effect on FTSTS was found at approximately 1 week after the real intervention. Muscle strength was unchanged in both limbs for both real and sham groups. Our results suggest that a single session of dual-tDCS before conventional physical therapy could improve sit-to-stand performance, which appeared to be improved over conventional physical therapy alone. However, strength performance was not increased after the combination treatment.

Abstract
In Thailand, individuals with stroke prefer to return home after being discharged from hospital and most of them have inconveniences to get to hospitals or clinics to receive physical therapy. Thus, home-based physical therapy (HBPT) might be an option. A retrospective pre-test and post-test study was conducted among 2,412 individuals with first stroke after receiving HBPT. It showed significant ( p < .0001) improvement in voluntary movement, postural balance, and activities of daily living (ADLs) in individuals with after-stroke duration of ≤20 years. Those with after-stroke duration of >20 years demonstrated significant development in voluntary movement ( p = .005) and postural balance ( p = .037), but not ADLs. In conclusion, HBPT improves voluntary movement, postural balance, and ADL in individuals following any period of first stroke, and might be an alternative service for them in Thailand.

Abstract
OBJECTIVE To determine the effects of 12-week leg exercise and follow-up on fasting blood glucose (FBG), blood pressure, static and dynamic standing balance time, leg muscle strength, and leg exercise behaviors in type 2 diabetic elderly. MATERIAL AND METHOD Fourfemales, completing 12-week leg exercise group and 6- and 12-monthfollow-up were examined for FBG blood pressure, standing on firm and foam surfaces, single leg stance, Five-Times-Sit-to-Stand Test (FTSST), alternated stepping, and leg muscle strength at before leg exercise, week 12 of exercise, and months 6 and 12 follow-up after exercise. Friedman's ANOVA was used to compare these variables among 4 periods. Exercise behaviors were asked at months 6 and 12follow-up. RESULTS Significant decreased time was observed in FTSST between before and at week 12, and alternated stepping between before and at month 6. For one year follow-up, two participants performed leg exercise regularly. According to patients' interviews, they continued leg exercise because ofreduced leg pain and stiffness, compliance to physiotherapist's suggestions, and exercise addiction. CONCLUSION Leg exercise enhanced FTSST and alternated stepping produced good qualityfeeling in leg in diabetic elderly. Physiotherapists may be a keyfor continuing leg exercise in community-dwelling diabetic elderly.

Abstract
OBJECTIVE The present study aimed to compare the effectiveness of the treatment programs of home-based exercise with and without self-manual therapy in individuals with knee osteoarthritis (knee OA) in community. MATERIAL AND METHOD Forty-three participants with knee OA were randomly assigned in groups. All participants received the same home-based exercise program with or without self-manual therapy over 12 weeks. Outcome measures were pain intensity, range of motions, six-minute walk test distance, the knee injury and osteoarthritis outcome score (KOOS), short-form 36 (SF-36) and satisfaction. RESULTS The results showed that the self-manual therapy program significantly decreased pain at 4 weeks, increased flexion and extension at 4 and 12 weeks, and improved the KOOS in pain item and SF-36 in physical function and mental health items. The home-based exercise group showed significant increase of the six-minute walk distance at 4 and 12 weeks, improvements in the KOOS in pain and symptom items and SF-36 in the physical function and role-emotional items. CONCLUSION Overall, the results favored a combination of self-manual therapy and home-based exercise for patients with knee OA, which apparently showed superior benefits in decreasing pain and improving active knee range of motions.

Abstract
OBJECTIVE To compare the effects of dyad and individual training on the learning of bimanual cup-stacking in individuals with chronic stroke. MATERIAL AND METHOD Twenty participants were divided into dyad and individual groups. The dyad group performed the task in pairs alternating between performing and observing, while the individual group performed individually. On the first day (acquisition phase: AP), allparticipants performed 20 trials. On the following day (retention phase: RP), they performed 10 trials; each participant individually performed five trials without verbal feedback followed by five trials with verbal feedback. The dependent measures were movement time (MT), which was a measure of motor execution, and reaction time (RT), a measure of motor planning. RESULTS During the initial trials, the dyad group performed the task with longer MT. By the end of the AP their time was significantly shorter At the R, only the dyad group maintained the improved MT of cup stacking. Although the RT was not different between the two groups at the RE, only the RTof the dyad group reduced significantly at the RP compared with block l of the AP CONCLUSION: In individuals with chronic stroke, the dyad training protocol greatly enhanced the execution speed of the bimanual cup-stacking task when compared with the individual training protocol. Planning the task also improves dyad training.

Abstract
OBJECTIVE To compare postural balance and visual verticality perception between neck pain and asymptomatic subjects; to determine its association within groups. MATERIAL AND METHOD Fourteen neck pain and 14 asymptomatic subjects participated in the study. Subjects stood on a force platform to measure the displacement of the center of pressure in the medial-lateral and anterior-posterior directions, total path length, and sway velocity. Subjects performed 10 patterns of the rod and frame test in the sitting position to measure absolute errors of visual verticality perception. Postural balance variables between neck pain and asymptomatic participants were determined by Independent t-test. Two-way analysis of variance determined the effect of absolute errors of visual verticality perception, groups and its interaction. The association between postural balance variables and absolute errors of visual verticality perception was determined by Pearson's correlation. RESULTS Neck pain patients showed greater total path length and sway velocity than asymptomatic subjects. Similar absolute errors of visual verticality perception between groups were shown. No correlation between postural balance variables and absolute errors of visual verticality perception within groups was demonstrated. CONCLUSION Postural balance, not visual verticality perception was disturbed in individuals with neck pain. Postural balance was not associated with visual verticality perception in individuals with and without neck pain.

Abstract
OBJECTIVE The present study was conducted to assess the factors explaining functional ability in community-dwelling individuals with stroke. MATERIAL AND METHOD In all, 758 persons with acute stroke who lived in the community and joined the home physical therapy program were recruited. The personal characteristics and clinical measures were recorded at the first home visit. Measures included Glasgow coma score, Stroke Rehabilitation Assessment of Movement (STREAM), Postural Assessment Scale for Stroke Patients (PASS) including PASS-maintaining position and PASS-changing position and Barthel index. RESULTS Five variables: the PASS-maintain, PASS-change, STREAM, Glasgow coma score, and age were selected by stepwise multiple regression analysis to explain 85.6% of the variance of the Barthel Index score. The strongest predictor was the PASS-maintain, which explained 81.5% of functional score. CONCLUSION The ability to maintain sitting and standing were the main contributors of activity daily living (ADL) ability. Physical therapists should emphasize treatment to improve these abilities in persons with acute stroke to promote independent ADL.

Abstract
OBJECTIVE Reach and grasp components must be co-ordinated to preserve the optimal reach-to-grasp performance. However conflicting results regarding the deficit in reach-to-grasp co-ordination has been reported in the paretic hand of individuals after stroke. Additionally, investigations have not been undertaken to study more challenging task constraints to induce the impairment of reach-to-grasp co-ordination. This study aimed to compare reach-to-grasp co-ordination while avoiding an obstacle in the paretic hand of individuals after stroke with matched non-disabled adults. MATERIAL AND METHOD Twenty-four participants having mild severity of upper extremity impairment were recruited with an equal number of non-disabled adults. Kinematic reach-to-grasp movements with obstacle avoidance were analyzed. Reach-to-grasp co-ordination was quantified using cross-correlation analysis: maximum correlation coefficient represented the spatial aspect and the time lag represented the temporal aspects. RESULTS Individuals after stroke showed a significant disturbance in the temporal aspect of reach-to-grasp co-ordination, but not the spatial aspect as compared with non-disabled adults. CONCLUSION Among participants, after stroke reach-to-grasp co-ordination was delayed in the temporal aspect of reach-to-grasp with obstacle avoidance but preserved in the spatial aspect. Specific methods to assess reach-to-grasp co-ordination and to treat the time delay to improve co-ordination should be considered in individuals after stroke.

Abstract
BACKGROUND Gait initiation is a major motor problem for patients with Parkinson's disease (PD). To understand the gait initiation in patients with PD, fluctuation on the first three steps of initiation was examined METHODS Force distribution measurement platform was used to record gait initiation in 10 patients with PD and healthy participants. Step length, step time and step width, as well as its coefficient of variation (CV) were investigated RESULTS The findings demonstrated significant main effect of group on step length (p < 0.001), step time (p = 0.034) and step width (p = 0.002), significant main effect of step on step time (p < 0.001) and step width (p < 0.001). No interaction between group and step (p > 0.05) was found on the variables. Compared with healthy participants, patients with PD showed significantly shorter step length in the first (p < 0.001), second (p = 0.001) and third (p = 0.001) steps and longer step time in the second step (p < 0.001). No difference in CV (p > 0.05) of the variables between groups comparison. Both groups had significant longer step time in the first step compared with the second step (PD, p < 0.001; healthy participants, p < 0.001) and the third steps (PD, p < 0.001; healthy participants, p < 0.001). They demonstrated significant wider step width in the first step when compared with the second step (PD, p = 0.043; healthy participants, p < 0.001) and the third steps (PD, p = 0.002; healthy participants, p < 0.001). CONCLUSION Patients with PD showed shorter step length of all steps, longer step time in the second step and similar step width when compared with healthy participants. Among the three steps, both groups demonstrated longer step time and wider step width in the first step when compared with other two step.

Abstract
The purposes of this study were to investigate the upper and contralateral lower limb coordination and to study the effect of speed on the upper and contralateral lower limb coordination in individuals with stroke and control groups. Thirty individuals with stroke who were able to walk independently without using any assistive devices and 30 control individuals were recruited for the study. Upper and contralateral lower limb coordination was analyzed using the shoulder and contralateral hip displacements in the sagittal plane. All data were analyzed by three-dimensional gait analysis. Results demonstrated high degrees of coordination in the upper and contralateral lower limbs of the controls and in the unaffected upper and affected lower limbs of individuals with stroke. Gait speed was found to be associated with the upper and contralateral lower limb coordination in individuals with stroke but not in the controls. The findings implied that the affected upper limb plays an important role for improving gait coordination and is necessary for gait performance in individuals with stroke. Thus, health professionals should exercise the affected arm to increase efficiency of walking in individuals with stroke.

Abstract
OBJECTIVE To determine test-retest reliability and absolute and relative minimal detectable changes at the 95% confidence level (MDC(95)) of measures to detect postural balance and lower limb movements in individuals with chronic stroke who were able to walk and had differences in ankle plantarflexor tone. DESIGN Test-retest study. Data were collected on 2 occasions, about 6 days apart. SETTING Outpatient physical therapy clinics. PARTICIPANTS Volunteers (N=61) with chronic stroke who were able to walk and had differences in ankle plantarflexor tone: no increase in ankle plantarflexor tone (n=12), a slight increase in ankle plantarflexor tone (n=32), and a marked increase in ankle plantarflexor tone (n=17). INTERVENTION Not applicable. MAIN OUTCOME MEASURES Reliability and absolute and relative MDC(95) of the Berg Balance Scale (BBS), the lower limb subscale of Fugl-Meyer Assessment (FMA-LE), the Timed "Up & Go" test (TUG), the comfortable gait speed (CGS), the fast gait speed (FGS), and the 2-minute walk test (2MWT). RESULTS Excellent reliability of the BBS, FMA-LE, TUG, CGS, FGS, and 2MWT for all the participants combined and for the subgroups was shown. All the participants combined showed the absolute and relative MDC(95) in the BBS of 5 points and 10%, FMA-LE of 4 points and 16%, TUG of 8 seconds and 28%, CGS of 0.2m/s and 34%, FGS of 0.1m/s and 21%, and 2MWT of 13m and 23%. The absolute and relative MDC(95) of the subgroups were varied based on ankle plantarflexor tone. CONCLUSIONS The BBS, FMA-LE, TUG, CGS, FGS, and 2MWT are reliable measures to detect postural balance and lower limb movements in individuals with chronic stroke who have differences in ankle plantarflexor tone. The absolute and relative MDC(95) of each measure are dissimilar in those with differences in ankle plantarflexor tone. The relative MDC(95) seems more useful than the absolute MDC(95) because the relative value can be used for a single individual.

Abstract
OBJECTIVE To investigate asymmetrical gait characteristics and degree of associations between gait symmetrical indexes and clinical measures in a stroke population. MATERIAL AND METHOD Thirty patients with stroke participated in the present study. Clinical measures included muscle tone of affected hip adductors (HA), hip extensors (HE), knee extensors (KE), ankle plantar flexors (AP) and ankle invertors (AI), lower extremity function and postural balance. Symmetrical indexes of gait biomechanics included braking peak force (Y1), propulsive peak force (Y2), first peak vertical force (Z1) and second peak vertical force (Z2), step length, single support time (SST), step time, stance time and swing time were determined. RESULTS The symmetrical index of force was significantly related with muscle tone and lower extremity function. Temporospatial variables significantly related to muscle tone and lower extremity function, but not to postural balance. CONCLUSION Muscle tone and lower extremity function were important for walking efficiency as the presented relationships with symmetrical gait characteristic in patients with a stroke.

Abstract
This study was designed to address an active reaching exercise on the purpose of determining the individual and interaction effects of reaching directions, assistance conditions and the muscles. The activity of the muscles, the Serratus Anterior and Pectoralis Major, in 20 healthy male subjects was recorded in parallel by surface electrode of electromyography. Four conditions of reaching, upward reaching in shoulder flexion 90(0) and sideward reaching in shoulder abduction 90(0) with and without arm support were tested. The results showed a significant decrease in the muscle activity in the sideward reaching when compared with the upward addition to with arm support when compared with without arm support. The Pectoralis Major was significantly less activated than the Serratus Anterior. There was a significant decrease in the Pectoralis Major and Serratus Anterior activation during sideward reaching when compared with the upward. Furthermore, Pectoralis Major and Serratus Anterior muscles during reaching with arm support were less activated than without the support. The interaction between reaching directions, assistance conditions and muscles revealed that the least activation for Pectoralis Major muscle was the sideward reaching with arm support whilst for Serratus Anterior was the sideward reaching with and without arm support. It is suggested that in clinical application, particularly in the spastic Pectoralis Major muscle patients, an active reaching exercise should be first done in the sideward direction with support.
