The effects of standard and modified LSVT BIG therapy protocols on balance and gait in Parkinson's disease: A randomized controlled trial.

BACKGROUND: Lee Silverman voice treatment (LSVT) BIG is an exercise program developed for patients with Parkinson's disease (PwPD), consisting of sets of exercises performed for 4 consecutive days a week for 4 weeks. However, the standard protocol suggests a treatment frequency difficult to follow for most patients who have difficulties reaching rehabilitation clinics. Our aim was to compare the standard LSVT BIG protocol with a modified LSVT (m-LSVT) BIG protocol (twice a week in the clinic for 4 weeks and twice a week at home for 4 weeks). METHODS: In this randomized controlled trial, 16 PwPD (aged 18-80 years, Hoehn and Yahr stages I-III) were recruited into two groups. The LSVT group received standard LSVT BIG training (four times per week for 4 weeks at the clinic). The other group was given m-LSVT BIG exercises, but unlike the LSVT group, the m-LSVT group exercised twice a week at the clinic and twice a week at home for 4 weeks. The Berg Balance Scale was used to assess functional balance. Biodex Balance System was used to assess laboratory balance measures. Timed Up and Go test and G-Walk sensor system were used to assess functional mobility and spatiotemporal gait analysis. RESULTS: Significant group-by-time interactions on the eyes open-firm surface score of the modified clinical test of sensory integration of balance (F = 10.138, p = .007) and gait cycle symmetry index (F = 10.470, p = .010) were found to be in favor of the LSVT group. Additionally, post hoc analyses revealed that both groups significantly improved postural stability, gait speed, motor symptoms, and functional mobility (p < .05). CONCLUSION: The results revealed the beneficial effects of the modified protocol on balance and gait in PwPD, as well as the superiority of the standard LSVT BIG protocol. The m-LSVT BIG protocol may be an effective intervention method, especially for PwPD who have difficulty adapting to the treatment frequency of the standard protocol.

Effects of Pilates-based telerehabilitation on physical performance and quality of life in patients with multiple sclerosis.

PURPOSE: It is known that clinical Pilates improves strength, core stability, balance, gait, fatigue, and quality of life (QOL) in patients with multiple sclerosis (PwMS). On the other hand, there is insufficient information about whether similar benefits can be achieved with Pilates-based telerehabilitation (Pilates-TR). We aimed to investigate the effects of Pilates-TR on physical performance and QOL in PwMS. METHODS: Thirty PwMS were recruited and randomly allocated into two groups. The Pilates-TR group received Pilates-TR via videoconferences three days per week during six weeks at home. The control group (CG) was a waitlist with no Pilates-TR treatment. Physical performance measures included extremity muscle strength, core endurance and power, balance, gait analysis, and functional exercise capacity. In addition, fatigue and QOL were evaluated. RESULTS: Extremity muscle strength, core endurance and power, balance, walking speed, cadence, distance, functional exercise capacity, and QOL were improved after Pilates-TR (p < 0.05). Fatigue level and the effects of fatigue on functions decreased in Pilates-TR, while fatigue level increased in CG (p < .05). The CG showed no changes in any other measurements (p > .05). CONCLUSION: Pilates-TR was effective in improving physical performance and QOL in PwMS. Pilates-TR can be recommended as an effective option, especially for patients with barriers to reaching the clinic.Trial registration: ClinicalTrials.gov (NCT04838886)IMPLICATIONS FOR REHABILITATIONPilates-based telerehabilitation (Pilates-TR) is an effective means of improving muscle strength, core stability, balance, walking, functional exercise capacity, and fatigue in patients with multiple sclerosis (PwMS).Pilates-TR seems like an appropriate option for improving both the mental and physical dimensions of quality of life in PwMS.Clinicians can safely use Pilates-TR to increase physical performance and quality of life in PwMS who have limitations to participate in clinical Pilates for various reasons.

The effect of task-oriented circuit training-based telerehabilitation on upper extremity motor functions in patients with Parkinson's disease: A randomized controlled trial.

INTRODUCTION: Upper extremity functions are impaired in patients with Parkinson's disease (PwPD), which leads to difficulties in activities of daily living (ADL), such as reaching or handwriting. The aim of this study was to investigate the effectiveness of task-oriented circuit training-based telerehabilitation (TOCT-TR) on the upper extremity motor function in PwPD. METHODS: In this randomized controlled trial (RCT) 30 PwPD (aged 45-70 years, Hoehn & Yahr stage I-III) were recruited and randomly allocated into two groups. The TOCT-TR group received home training through video sessions three days/week for six weeks. Additionally, both the TOCT-TR group and the control group (CG) underwent home exercises aimed at improving balance, gait, and mobility three days/week for six weeks. The primary outcome measure was upper extremity motor functions measured with the Nine Hole Peg test (9-HPT), the Jebsen Hand Function Test (JHFT), grip strengths, pinch strengths, and the Unified Parkinson's Disease Rating Scale-III (UPDRS-III). Secondary outcome measures included the UPDRS-II and the quality of life (QoL, PDQ-8). RESULTS: This study showed significant group-by-time interactions on the 9-HPT (p < 0.001), the JHFT (p < 0.001), grip strengths (p < 0.001), pinch strengths (p ≤ 0.015), and the UPDRS-III (p = 0.007) in favor of the TOCT-TR. Additionally, the UPDRS-II (p < 0.001), and the PDQ-8 (p = 0.005) improved in both groups. CONCLUSION: This is the first RCT showing that the TOCT-TR improved upper extremity motor functions, ADL, and QoL in PwPD. The TOCT-TR may help improve the upper extremities of PwPD who have difficulties reaching rehabilitation clinics.

Effects of multi-task training on motor and cognitive performances in multiple sclerosis patients without clinical disability: a single-blinded randomized controlled trial.

OBJECTIVE: This study aimed to investigate the effects of multi-task training on motor and cognitive performance in People with Multiple Sclerosis (PwMS) without clinical disability compared to single-task training and a control group. METHODS: A total of 42 patients were randomly assigned to three groups labeled as Multi-Task Training Group (MTTG, n:14), Single-Task Training Group (STTG, n:14), and Control Group (CG, n:14). The STTG performed only motor tasks based on the task-oriented training program twice a week for 6 weeks while the MTTG performed the same tasks concurrently with additional motor and cognitive tasks. The CG performed relaxation exercises at home. Postural stability by posturography, walking by Timed Up-and-Go, manual dexterity by Nine-Hole Peg Test, mental tracking by Counting Backward, and verbal fluency by Word List Generation were assessed before and after the intervention under single and dual-task conditions. RESULTS: In the MTTG, both single cognitive and single motor task performances increased, and, moreover, the cognitive Dual-Task Costs (DTCs) decreased although the motor DTCs were not changed significantly. There were significant group-by-time interactions in favor of MTTG only on the mental tracking DTC during walking compared to the STTG. Moreover, the changes in postural and walking DTCs were associated with changes in single-motor task performance. CONCLUSION: This study suggests that multi-task training is effective in reducing cognitive DTC rather than motor DTC under dual-task conditions in PwMS without clinical disability. TRIAL REGISTRATION NUMBER: NCT03512886.

The effects of augmented and virtual reality gait training on balance and gait in patients with Parkinson's disease.

OBJECTIVE: Augmented reality (AR) and virtual reality (VR) facilitate motor learning by enabling the practice of task-specific activities in a rich environment. Therefore, AR and VR gait training may improve balance and gait in Parkinson's Disease (PD). METHODS: Thirty patients with PD were randomly divided into study (n = 15) and control (n = 15) groups. The study group was given AR and VR gait training combined with conventional training. The control group was given conventional training only. The training was applied to both groups 3 days a week for 6 weeks. Motor symptoms with the Unified Parkinson Disease Rating Scale-Motor Examination (UPDRS-III), balance with posturography and Berg Balance Scale (BBS), perceived balance confidence with Activity-Specific Balance Confidence Scale (ABC), gait with spatio-temporal gait analysis, and functional mobility with Timed Up and Go Test (TUG) were assessed. RESULTS: At the end of the study; UPDRS-III, posturography measurements, BBS, ABC, spatio-temporal gait parameters, and TUG improved in the study group (p < 0.05), while BBS, ABC, and only spatial gait parameters (except for step width) improved in the control group (p < 0.05). There was no change in posturography measurement, temporal gait parameters, and TUG in control group (p > 0.05). When the developed parameters in both groups were compared, the amount of improvement in BBS and ABC was found similar (p > 0.05), while the improvement in the other parameters was found higher in the study group (p < 0.05). CONCLUSION: It was concluded that AR and VR gait training provides the opportunity to practice walking with different tasks in increasingly difficult environments, thus improving balance and walking by facilitating motor learning.

Functional Performance, Leg Muscle Strength, and Core Muscle Endurance in Multiple Sclerosis Patients With Mild Disability: A Cross-Sectional Study.

This study aimed to investigate the relationship of sit-to-stand and walking performance with leg muscle strength and core muscle endurance in people with multiple sclerosis (PwMS) with mild disabilities. In this study, 49 PwMS (Expanded Disability Status Scale score = 1.59 ± 0.79) and 26 healthy controls were enrolled. The functional performances, including sit-to-stand and walking performances, were evaluated with the five-repetition sit-to-stand test, timed up and go test, and 6-min walking test. The PwMS finished significantly slower five-repetition sit-to-stand, timed up and go, and 6-min walking test than the healthy controls. In addition, the significant contributors were the weakest trunk lateral flexor endurance for five-repetition sit-to-stand; the Expanded Disability Status Scale score, and the weakest hip adductor muscle for timed up and go; the weakest hip extensor muscles strength for 6-min walking test. The functional performances in PwMS, even with mild disabilities, were lower compared with healthy controls. Decreases in both leg muscle strength and core muscle endurance are associated with lower functional performance in PwMS.

The reliability and validity of the Turkish version of the dual-task questionnaire in patients with multiple sclerosis.

BACKGROUND: Activities of daily living often require performing dual-task (DT). People with Multiple Sclerosis (PwMS) may have difficulties during dual-task and these difficulties negatively affect their quality of life. However, the number of validated questionnaires to assess DT difficulties in Multiple Sclerosis (MS) is very few. Therefore, the study aimed to translate and adapt the Dual-Task Questionnaire (DTQ) into Turkish, thereafter analyzing the psychometric properties in PwMS. METHODS: A total of 51 PwMS were recruited in the study. Cronbach's alpha coefficient was used to evaluate internal consistency. The test-retest reliability was determined using the intraclass correlation coefficient (ICC). Correlations of the DTQ with motor-dual task costs (DTCs) and cognitive-DTCs were used to assess construct validity. RESULTS: The mean age was 36.84±10.47 years. The internal consistency of the DTQ was acceptable (α= 0.780). The test-retest reliability of all items and the total score of the DTQ were excellent (ICC>0.90). The relationships of DTQ-Total between some parameters of motor-DTCs (ρ=-0.409-(-0.495) for walking-DTCs, ρ=-0.313 for manual dexterity-DTC during mental tracking, and ρ=-0.353 for balance-DTC during mental tracking) and cognitive-DTCs (ρ=0.328 for mental tacking-DTC during balance, ρ=0.290-0.342 for all verbal fluency-DTCs) were low to moderately significant. CONCLUSION: Turkish version of DTQ is a reliable and valid tool to measure DT difficulty in PwMS. Additionally, the questionnaire is a reliable and valid Patient Reported Outcomes Initiative for MS (PROMS) for Turkish-speaking PwMS.

The functional reach test in people with multiple sclerosis: a reliability and validity study.

BACKGROUND: Limits of stability (LOS) is a major component of balance dysfunction in people with multiple sclerosis (MS). The functional reach test (FRT) is a clinical LOS assessment; however, its psychometric properties have not been investigated in people with MS yet. Objectives: To investigate: (1) the intrarater, interrater, and test-retest reliability of the FRT in people with MS; (2) the minimum detectable change (MDC) in the FRT distances; (3) the concurrent and discriminant validity of the FRT; and (4) the cutoff distance that best discriminates people with MS from healthy people and fallers from non-fallers with MS. METHODS: Forty-three people with MS and 36 healthy people participated in this study. The FRT was administered along with the instrumented LOS test, Berg Balance Scale, Four Square Step Test, Timed Up and Go Test, and Expanded Disability Status Scale. The FRT was repeated by the same rater after 2 min from the first test session to determine the intrarater reliability and was simultaneously conducted by two independent raters to determine the interrater reliability. The FRT was also repeated after 7-10 days to determine the test-retest reliability. The reliability was quantified using intraclass correlation coefficients (ICC), Bland-Altman plots, and the MDC. The validity was assessed by correlating the FRT distances with the scores of other measures and by comparing the FRT distances between the MS group and healthy people, and between the fallers and non-fallers in the MS group. RESULTS: The FRT demonstrated good to excellent intrarater, interrater, and test-retest reliability with an ICC (3,1) of 0.80-0.88 (p < .001), an ICC (3,2) of 0.94-0.97 (p < .001), an ICC (2,3) of 0.84-0.86 (p < .001), respectively. Bland-Altman analyses showed no systematic bias between the assessments. The MDC was 8.28 centimeters. The FRT was correlated with the other outcome measures (correlation coefficients ranged from 0.31 to 0.79, p < .05 for all). Significant differences in the FRT distances were found between people with MS and healthy people; however, no significant difference was found between the fallers and non-fallers with MS (p < .001 and p = .09, respectively). The cutoff distance of 35.5 centimeters best discriminates healthy people from people with MS while of 28.5 centimeters did not discriminate between the fallers and non-fallers with MS. CONCLUSIONS: The FRT is a reliable, valid, and easy-to-administer tool for assessing LOS in people with MS.

Effects of task-oriented training combined with aerobic training on serum BDNF, GDNF, IGF-1, VEGF, TNF-α, and IL-1ß levels in people with Parkinson's disease: A randomized controlled study.

INTRODUCTION: Parkinson's disease (PD) is a chronic neurodegenerative disease characterized by the death of dopaminergic neurons in the substantia nigra pars compacta. Exercise training, which is incorporated both goal-based training such as task-oriented training (TOT) and aerobic training (AT), has been suggested to induce neuroprotection. However, molecular mechanisms which may underlie exercise-induced neuroprotection are still largely unknown. Thus, the aim of the present study was to investigate the effects of TOT combined with AT (TOT-AT) on serum brain-derived neurotrophic factor (BDNF), glial cell-derived growth factor (GDNF), insulin-like growth factor-1 (IGF-1), vascular endothelial growth factor (VEGF), tumor necrosis factor-α (TNF-α), and interleukin-1ß (IL-1ß) levels in people with PD (PwPD). METHODS: Forty PwPD were randomized into 8-week of either exercise group (n = 20) or control group (n = 20). The exercise group received TOT-AT while the control group received only AT. Serum BDNF, GDNF, IGF-1, VEGF, TNF-α, and IL-1ß levels determined with ELISA were assessed at baseline and after training. RESULTS: A total of 29 PwPD completed this study. Our results showed no significant change in the serum BDNF, GDNF, IGF-1, VEGF, TNF-α, and IL-1ß levels in both groups. After the intervention period, no significant difference was observed between the groups regarding the serum BDNF, GDNF, IGF-1, VEGF, TNF-α, and IL-1ß levels. CONCLUSION: TOT-AT could not be an effective exercise method for changing serum concentrations of BDNF, GDNF, IGF-1, VEGF, TNF-α, and IL-1ß in the rehabilitation of PD.

Dual-Task Cost and Related Clinical Features in Patients With Multiple Sclerosis.

This study aimed to investigate the dual-task cost of both motor and cognitive performances in patients with multiple sclerosis (PwMS) and in healthy controls and to determine their relationships with clinical features in PwMS. The participants performed motor tasks (postural stability, walking, and manual dexterity) and cognitive tasks (mental tracking and verbal fluency) under single- and dual-task conditions. The results showed that postural stability under dual-task conditions did not change, whereas walking and manual dexterity deteriorated, regardless of the concurrent cognitive task, in PwMS (median Expanded Disability Status Scale score: 1) and the healthy controls. Verbal fluency decreased during postural stability, whereas it increased during walking, and it was maintained during manual dexterity in both groups. Mental tracking did not change during walking; it declined during manual dexterity in both groups. Mental tracking during postural stability deteriorated in PwMS, while it did not change in the healthy controls. In general, dual-task costs were associated with baseline performances of tasks rather than clinical features. Therefore, baseline performances of both tasks should be increased for improving dual-task performance in PwMS.

Task-oriented circuit training combined with aerobic training improves motor performance and balance in people with Parkinson's Disease.

Goal-based training such as task practice combined with aerobic training (AT) has been suggested to improve motor performance and neuroplasticity for people with Parkinson's Disease (PwPD); however, its effect on clinical outcomes is unclear. Therefore, the main aim was to investigate the effects of task-oriented circuit training combined with AT (TOCT-AT) on balance and gait in PwPD. The secondary aim was to investigate the effects of TOCT-AT on functional mobility, balance confidence, disease severity, and quality of life. Twenty-six PwPD were randomly assigned to either to the experimental group (n = 14) or the control group (n = 12). The control group received AT, while the experimental group received TOCT-AT three times a week for 8 weeks. The main outcomes were the Berg Balance Scale (BBS), Postural Stability Test (PST), Limits of Stability Test (LOS), Pull Test (PT), Six Minute Walk Test (6MWT), Timed Up and Go Test (TUG), Activities-specific Balance Confidence Scale (ABC), Unified Parkinson's Disease Rating Scale (UPDRS), and eight-item Parkinson's Disease Questionnaire (PDQ-8) were secondary outcomes. After intervention, between-group comparisons showed that the experimental group significantly improved more than the control group in all outcomes (p < 0.05). Additionally, both groups significantly improved in BBS, 6MWT, TUG, ABC, UPDRS-II, UPDRS-III, UPDRS total, and PDQ-8 (p < 0.05), while only the experimental group significantly improved in PST, LOS, and PT (p < 0.001). This study suggest that TOCT-AT could improve balance and gait performance, which could also be positively translated into functional mobility, balance confidence, disease severity, and quality of life in PwPD.

Reliability and validity of the timed 360° turn test in people with multiple sclerosis.

Objectives: To investigate (1) the intrarater, interrater, and test-retest reliability of the timed 360° turn test in people with Multiple Sclerosis (MS); (2) the minimum detectable change in the timed 360° turn test times; (3) the concurrent and discriminant validity of the timed 360° turn test times; and (4) the cut-off times that best discriminate people with MS from healthy people and fallers from non-fallers with MS.Method: Sixty-one people with MS (Expanded Disability Status Scale, EDSS, 0-6.5) and 34 healthy people were recruited in this cross-sectional study. The timed 360° turn test was administered along with the Timed Up and Go Test, Berg Balance Scale, Four Square Step Test, and EDSS by two independent raters.Results: The timed 360° turn test showed good intrarater, interrater, and test-retest reliability. Minimal detectable changes were 1.49 s and 1.53 s for the dominant and non-dominant sides, respectively. The timed 360° turn test was strongly correlated with other outcome measures. Significant differences in 360° turn times were found between people with MS and healthy people and between fallers and non-fallers with MS (p < .001 and p < .001, respectively). The cut-off times of 2.65 s on the dominant side and 2.42 s on the non-dominant best discriminated people with MS from healthy people, while 3.65 s on the dominant side and 3.75 s on the non-dominant best discriminated fallers from non-fallers with MS.Conclusions: The timed 360° turn test is a simple and reliable tool for assessing turning ability in MS.

Reliability and validity of the Turkish version of the vestibular rehabilitation benefit questionnaire

Background/aims: Vestibular rehabilitation has an important role in the reduction of symptoms and in the recovery of patients in peripheral vestibular pathologies. Objective and subjective vestibular assessment tools are needed to assess vestibular rehabilitation effectiveness. The aims of the study were to develop the Turkish version of the internationally used Vestibular Rehabilitation Benefit Questionnaire (VRBQ) measure and to demonstrate the reliability and validity properties of the Turkish version in patients with peripheral vestibular hypofunction (PVH). Materials and methods: 110 patients with unilateral PVH were included. For the analysis of test-retest reliability, Turkish version of VRBQ developed by translation-back translation method was applied to patients on the day of admission and the day after admission. To assess validity, patients were also evaluated with the VRBQ, Dizziness Handicap Inventory (DHI), Vertigo Symptom Scale-Short Form (VSS-SF), Vertigo Dizziness Imbalance (VDI) Questionnaire. Results: The VRBQ showed moderate to excellent internal consistency in total score and subscales scores (VRBQ-total Cronbach's α = 0.91; dizziness α = 0.81; anxiety α = 0.68; motion-provoked dizziness α = 0.89; aypmtoms α = 0.88; health-related quality of life α = 0.87). In the test-retest reliability of VRBQ-total score was excellent (ICC = 0.94). The dizziness, the anxiety, the motion-provoked dizziness, symptoms and the health-related quality of life domains' ICC were found respectively 0.90, 0.89, 0.84, 0.90, and 0.92. The construct validity of the VRBQ was determined. The VRBQ total was correlated with all parameters (r: 0.308 to ­0.699, P < 0.05). The highest positive correlation was found between VRBQ total and DHI-functional (r: 0.680). The highest negative correlation was found between VRBQ total and VDI-total (r: ­0.699). Conclusion: The results suggest that the Turkish version of the VRBQ is reliable and valid for evaluating the vestibular rehabilitation results.

Clinical features and physical performance in multiple sclerosis patients with and without cognitive impairment: a cross-sectional study.

The factors associated with cognitive functions in patients with multiple sclerosis (PwMS) are not yet clear. The aims of this study were (1) to compare clinical features and physical performance in healthy controls, and PwMS with and without cognitive impairment, and (2) to determine the relationship between cognitive domains and demographics characteristics, clinical features and physical performance in PwMS. A total of 112 PwMS and 25 healthy controls participated in this study. Cognitive functions were evaluated by Brief Repeatable Battery of Neuropsychological Tests (BRB-N). Based on cognitive performances by BRB-N, PwMS were divided into two groups as MS patients with impaired (MS-I, n: 57) and with normal (MS-N, n: 55) cognitive functions. For clinical features, fatigue, mood and sleep quality were evaluated by the Fatigue Impact Scale, Beck's Depression Inventory, Pittsburgh Sleep Quality Index, respectively. For physical performances, balance and walking capacity were evaluated by posturography and Six-Minute Walking Test, respectively. The results showed that the education years, postural stability and walking capacity in MS-N and healthy controls were higher than in MS-I (P < 0.05). In addition, visuospatial memory was correlated with both postural stability under all sensory conditions and walking capacity; verbal memory was correlated with education years, postural stability on eyes closed-foam surface and walking capacity; verbal fluency was correlated with only walking capacity; information processing speed was correlated with education years, postural stability under all sensory conditions and walking capacity (P < 0.001). This study suggests that the interventions that aim to improve physical performance might protect and even improve cognitive functions in PwMS.

Combined exercise training improves cognitive functions in multiple sclerosis patients with cognitive impairment: A single-blinded randomized controlled trial.

BACKGROUND: Cognitive impairment is common in patients with multiple sclerosis (MS). The effects of different exercise trainings on cognitive functions in patients with MS are promising. However, the effects are not yet clear in MS patients with cognitive impairment. This study aimed to investigate the effect of combined exercise training on different cognitive functions in MS patients with cognitive impairment. METHODS: Relapsing-remitting and mild disabled MS patients with cognitive impairment were randomly assigned to two groups: Exercise Group (EG, n:17) and the Control Group (CG, n:17). The EG received a combined exercise training consisting of aerobic and Pilates training in three sessions per week for 8 weeks while the CG performed the relaxation exercises at home. Cognitive functions, walking capacity, fatigue, mood, and quality of life were assessed at baseline and after eight weeks using the Brief Repeatable Battery of Neuropsychological Tests (BRB-N), Six-Minute Walk Test (6-MWT), Fatigue Impact Scale (FIS), Beck's Depression Inventory (BDI) and MS Quality of Life-54 (MSQoL-54), respectively. RESULTS: This study showed significant group-by-time interactions on long-term verbal memory, walking capacity, cognitive fatigue, and physical quality of life in favor of the EG (p<0.003). Moreover, verbal memory, visuospatial memory, verbal fluency, information processing speed, walking capacity, fatigue, and quality of life improved in the EG (p<0.05) while only verbal memory increased in the CG (p<0.05). Furthermore, the change in visuospatial memory was associated with the change in mental quality of life (r:0.352, p: 0.041) while the change in verbal fluency (r: -0.362, p:0.035) and processing speed (r: -0.356, p:0.039) were associated with the change in mood. CONCLUSION: Combined exercise training has beneficial effects on different cognitive functions in mild disabled RRMS patients with cognitive impairment. In addition, there is a mutual relationship in improvements in cognitive functions, mood, and quality of life after exercise.

Validity and reliability of the Turkish version of the Self-reported Foot and Ankle Score in patients with foot or ankle pain.

OBJECTIVE: The aim of this study was to translate the Self-Reported Foot and Ankle Score (SEFAS) into Turkish and to determine the validity and reliability of the translated version in patients with foot or ankle pain. METHODS: A total of 98 patients (65 females, 33 males, mean age=39 years, age range 18-65 years) who presented with foot or ankle pain for at least one week were included in the study. SEFAS was translated into Turkish (SEFAS-T) and then back-translated into English by two bilingual translators to ensure the accuracy of translation. To determine the validity of the translated version, SEFAS-T, The Foot and Ankle Outcome Score (FAOS), and the Short Form 36 (SF-36) were administered at the first assessment on the same day. SEFAS-T was repeated five days later (Spearman's rho). Intra-class correlation coefficients (ICCs) were used for assessment of the test re-test reliability, while the Cronbach's alpha coefficient was used to assess the internal consistency of the questionnaire Results: SEFAS-T showed good test-retest reliability (ICC: 0.887). Item 4 showed poor item-total correlation and inter-item correlations. When item 4 was excluded, the Cronbach's alpha value was found as 0.906. SEFAS-T total scores showed correlation with all the FAOS sub-scores (p<0.001) and all the SF-36 components (p≤0.001) except mental health (rho: 0.149, p: 0.143). The highest correlation was found between SEFAS-T Total Score and the Sports and Recreations subscale of FAOS (rho: 0.796, p<0.001). CONCLUSION: SEFAS-T seems to be valid and reliable as a measure for foot or ankle pain in Turkish patients. LEVEL OF EVIDENCE: Level II, Diagnostic study.

Effect of task-oriented circuit training on motor and cognitive performance in patients with multiple sclerosis: A single-blinded randomized controlled trial.

BACKGROUND: Exercise training has positive effects on motor and cognitive performance which deteriorates over time in patients with Multiple Sclerosis (MS). The effects of task-oriented circuit training (TOCT) on motor and cognitive performance in patients with MS are not yet clear. OBJECTIVE: The aims of this study are to investigate the effects of TOCT on balance, walking, manual dexterity, cognitive performance, and to determine the extent to which patients are able to transfer changes in their performance to activities of daily living. METHODS: Twenty patients with MS (EDSS: 2-5.5), were randomly assigned to two groups; the task-oriented circuit training group (TOCTG, n:10) and the control group (CG, n:10). The TOCTG received TOCT twice a week for six weeks while the CG performed the relaxation exercises at home. All patients were assessed by using Modified Sensory Organization Test, Berg Balance Scale, Activities-specific Balance Confidence, Timed Up and Go, Functional Gait Assessment, 12-item Multiple Sclerosis Walking Scale, Nine-Hole Peg Test, Brief Repeatable Battery of Neuropsychological Tests, Multiple Sclerosis Neuropsychological Questionnaire. RESULTS: Balance and walking performance were improved after TOCT (p < 0.05), whereas manual dexterity and cognitive performance except for verbal memory did not change significantly (p > 0.05). The CG showed no changes in any measurements (p > 0.05). CONCLUSIONS: TOCT is quite effective to improve balance and walking in patients with MS. However, further studies are needed to determine the effect of TOCT on cognitive performance.

Reliability and validity of the timed 360° turn test in people with Parkinson's disease.

PURPOSE: The objectives of this study were to examine (1) the intrarater, interrater, and test-retest reliability of the timed 360° turn test in people with Parkinson's Disease (PwPD); (2) the minimum detectable change in the timed 360° turn test times; (3) the concurrent and discriminant validity of the timed 360° turn test; (4) the cut-off times which best discriminate PwPD from healthy people and fallers from non-fallers with Parkinson's Disease (PD). METHODS: Fifty-four PwPD and 32 healthy people were included. The timed 360° turn test was administered along with Timed Up and Go Test, Berg Balance Scale, Four Square Step Test, Unified Parkinson's Disease Rating Scale, and Hoehn and Yahr Scale. In addition, PwPD were categorized into fallers and non-fallers based on fall history. Reliability analyses were assessed using intraclass correlation coefficients in a subgroup of 38 PwPD. RESULTS: The timed 360° turn test had excellent intrarater, interrater, and test-retest reliability. It was strongly correlated with other outcome measures (p < 0.001). In both sides, significant differences in the timed 360° turn test times were found between PwPD and healthy people and between fallers and non-fallers with PD (p < 0.001 and p < 0.001, respectively). The timed 360° turn test times of 3.76-3.89 s were found to best discriminate PwPD from healthy people, while 5.46-5.74 s were found to best discriminate fallers from non-fallers with PD. The minimum detectable change in the timed 360° turn test times were 1.98 s for dominant side and 1.48 s for non-dominant side in PwPD. CONCLUSIONS: The timed 360° turn test is a reliable, valid, and clinically available tool for assessing turning ability in PwPD.

The sensitivity and specificity of the balance evaluation systems test-BESTest in determining risk of fall in stroke patients.

BACKGROUND: Balance disorders cause disability in stroke and increase risk of falls. The Balance Evaluation Systems Test (BESTest), examines balance, determines parameters causing balance disorders, provides information on risk factors for falls. OBJECTIVE: To investigate the sensitivity and specificity of the BESTest in determining the risk of falls in stroke patients. METHODS: Fifty patients with chronic stroke were included in the study. Balance was assessed using BESTest, Berg Balance Scale (BBS), Activity Specific Balance Confidence scale (ABC) and Biodex-BioSway Balance System. To examine the content validity of BESTest, the relationship between BESTest and other balance assessment methods was examined. The internal consistency reliability of BESTest was evaluated by Cronbach's α coefficient. Analysis of receiver operating characteristics (ROC) was performed to determine cut-off point, sensitivity and specificity. RESULTS: BESTest, BBS, ABC and Biodex-BioSway Balance System results of faller stroke patients were worse than that of non-faller (p <0.05). Internal consistency of BESTest was found to be Cronbach's α = 0.960. The BESTest value of area under curve (AUC) was 0.844, with a cut-off point of 69.44%, a sensitivity of 75% and a specificity of 84.6% (p < 0.01). CONCLUSION: BESTest is reliable and valid with high sensitivity and specificity in determining the risk of fall in stroke patients.

The effects of early neurodevelopmental Bobath approach and mobilization on quadriceps muscle thickness in stroke patients

Background/aim: Following stroke, damage to the central nervous system and adaptive changes in muscle tissue are factors responsible for the loss of muscle strength. Even though it is suggested that early physiotherapy and mobilization prevent structural adaptive changes in muscle tissue, studies regarding this issue are insufficient. The aim of this study is to investigate the effects of early physiotherapy and mobilization on quadriceps muscle thickness (QMT) in stroke patients. Materials and methods: Twelve stroke patients who were admitted to the neurology intensive care unit and 13 healthy controls were included in the study. QMT was examined at admission and discharge for each subject. Additionally, functional extremity movements, balance, and functional ambulation status were evaluated with the Stroke Rehabilitation Assessment of Movement Scale (STREAM). All of the patients were mobilized as early as possible by a physiotherapist and included in a treatment program consisting of the neurodevelopmental Bobath approach. Results: The patients' QMT values at admission and discharge were found to be similar to those of the healthy control group (P > 0.05). When the patients' QMT at the time of admission and discharge were compared, it was seen that the affected side and the nonaffected side were similar (P > 0.05). Additionally, when the admission and discharge results were compared, improvements in functional extremity movements, balance, and functional ambulation levels were observed (P < 0.05). Conclusion: It can be seen that QMT can be preserved and functional improvements can be provided through intense physiotherapy and mobilization initiated in the early period following stroke.
