Abstract Objective: In this study, we systematically reviewed the efficacy of tango in alleviating the motor symptoms of patients with Parkinson's disease (PD).Methods: We searched internet databases, such as PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science Core collection, and CNKI, for studies examining the effects of tango on the motor symptoms of patients with Parkinson's disease, published from September 2021 to date. All types of tango intervention, including traditional tango, Argentinian tango, and adapted tango, were examined in our review. The Cochrane bias risk assessment tool was used to evaluate the quality of methodologies used in the included studies. RevMan 5.4 software was used for meta-analysis.Result: Eleven studies that included 390 Parkinson's patients met our inclusion criteria. Meta-analysis indicated that after tango, PD patients showed a considerable decrease in the overall severity of motor symptoms and improvement in balance, functional mobility, fast gait velocity, preferred gait velocity, stride length, and gait cadence. Compared with exercise, tango showed stronger effects on balance and functional mobility; however, no significant differences in the severity of motor symptoms, fast gait velocity, or preferred gait velocity were observed between the group treated using tango and that treated using exercise.Conclusion: Interventions using tango may help alleviate the severity of motor symptoms, and specifically promote balance and functional mobility, in patients with Parkinson's disease. However, except for improving balance and functional mobility, tango showed no significant advantages over exercise in alleviation of motor symptoms in patients with Parkinson's disease.

BACKGROUND: Fear of falling avoidance behavior (FFAB) is common in parkinsonisms and results in potentially mitigable downstream consequences. OBJECTIVE: Determine the characteristics of individuals with parkinsonisms most associated with FFAB. METHODS: A retrospective, cross-sectional study was conducted from medical records data of 142 patients with parkinsonisms. These data included: demographics (age, sex), disease severity (Movement Disorders Society –Unified Parkinson’s Disease Rating Scale Part III (MDS-UPDRS III), years since diagnosis), fall history (number of fall injuries in previous year), and gait and balance function (five times sit to stand, MiniBESTest, Timed Up and Go (TUG), dual-task TUG, ten-meter walk test (10MWT), observed freezing of gait (FOG) (MDS-UPDRS III item 11)). RESULTS: 10MWT (p <  .001) and MDS-UPDRS III item 11 (p <  .014) were significantly associated with FFAB above and beyond disease severity, which also contributed significantly to the overall model (ps <  .046). Fall history was not associated with FFAB. CONCLUSION: Our findings suggest that the largest portion of variability in FFAB is explained by gait velocity and FOG; however, disease severity also explains a significant portion of the variability of FFAB. Further investigation into factors predictive of FFAB and mitigation of downstream consequences, using more robust designs, is warranted.

BACKGROUND: Patients with cerebellar ataxia report oscillopsia, “bouncy vision” during activity, yet little is known how this impacts daily function. The purpose of this study was to quantify the magnitude of oscillopsia and investigate its relation to vestibulo-ocular reflex (VOR) function and daily activity in cerebellar ataxia. METHODS: 19 patients diagnosed with cerebellar ataxia and reports of oscillopsia with activity were examined using the video head impulse test (vHIT), Oscillopsia Functional Index (OFI), and clinical gait measures. Video head impulse data was compared against 40 healthy controls. RESULTS: OFI scores in ataxia patients were severe and inversely correlated with gait velocity (r = –0.55, p <  0.05), but did not correlate with VOR gains. The mean VOR gain in the ataxic patients was significantly reduced and more varied compared with healthy controls. All patients had abnormal VOR gains and eye/head movement patterns in at least one semicircular canal during VHIT with passive head rotation. CONCLUSIONS: Patients with cerebellar ataxia and oscillopsia have impaired VOR gains, yet severity of oscillopsia and VOR gains are not correlated. Patients with cerebellar ataxia have abnormal oculomotor behavior during passive head rotation that is correlated with gait velocity, but not magnitude of oscillopsia.

<b><i>Background:</i></b> Circulating osteoprogenitor (COP) cells are a surrogate of the bone marrow mesenchymal stem cells with high levels observed in osteoporosis and the initial stages of fracture healing. Conversely, a low percentage of COP cells (%COP) is strongly associated with frailty and disability. However, it is unknown whether %COP is associated with sarcopenia, a musculoskeletal disease closely related to frailty. <b><i>Objectives:</i></b> This study sought to determine the associations between %COP and sarcopenia defined using the Sarcopenia Definitions and Outcomes Consortium (SDOC) criteria. <b><i>Methods:</i></b> Data from a random sample of 73 community-dwelling older persons enrolled in the Nepean Osteoporosis and Frailty study (median age 74 years; 60% female) were analyzed. %COP was quantified by flow cytometry using selective gating of CD45/osteocalcin (OCN) + cells. Sarcopenia was defined using handgrip strength and gait speed with cut points as per the SDOC criteria. Linear regression was used for analysis. <b><i>Results:</i></b> Sarcopenia was identified in 19% of participants, all of whom were frail. After adjusting for age, sex, and interleukin 6, sarcopenic participants had 36% lower %COP (95% confidence interval [CI] −56%, −6%, <i>p =</i> 0.024). Both grip strength and gait speed showed associations with %COP (<i>p =</i> 0.065 and 0.002, respectively); however, after adjusting for age and frailty, only gait speed remained associated with %COP (0.1 m/s increase in gait velocity was associated with a 5% increase in %COP cells (95% CI 0%, 10%, <i>p =</i> 0.052). <b><i>Conclusions:</i></b> High levels of %COP are associated with better muscle function. Future longitudinal studies are required to elucidate the clinical utility of %COP as a potential biomarker or disease stratifier for sarcopenia.

Objective — to identify the most significant markers of gait that indicate a decrease in cognitive function based on investigation of the corelation of cognitive impairment, gait parameters and atrophy of brain structures in groups of patients with Parkinson’s disease and the «normally aging population». Methods and subjects. 66 subjects were examined: 30 patients with Parkinson’s disease (mean age 54.9 ± 5.9, 50 % men) and 33 without neurological pathology (mean age 52.7 ± 7.6, 66 % men). All of them underwent neurological examination, assessment of temporal and spatial gait parameters using the GaitRite system, grading of brain atrophy using a comprehensive visual rating scale of MRI scans and assessment of cognitive status using the Montreal Cognitive Assessment Scale. Results. Cognitive performance was significantly lower in the subgroup of patients with Parkinson’s disease compared to the subgroup of «normally aging population». The gait profile of patients with Parkinson’s disease significantly differed from the gait profile of individuals from the «normal aging» subgroup by slower gait velocity, shorter step length and stride length for both limbs. The gait parameters, which showed a strong correlation with cognitive tests, differed in the subgroups, but gait velocity, stride length and step length for both extremities were common among them. These common gait parameters showed a strong direct correlation with brain atrophy in the subgroup of patients with Parkinson’s disease, but only velocity correlated with atrophy in the subgroup of «normal aging» among all of them. It was determined by the method of multiple regression analysis that it was precisely the atrophy of the brain that turned out to be the most influential factor in the decrease in cognitive function in the general group and subgroups. Conclusions. The gait profile in Parkinson’s disease subgroup is characterized by lower velocity, shorter step length, stride length for both limbs and significantly differs from the subgroup of «normal aging». These changes are a consequence of the influence of the disease on the motor sphere. Velocity showed a strong correlation in both subgroups not only with cognitive abilities, but also with cerebral atrophy. This confirms the hypothesis about the possibility of using gait velocity as a universal sensitive marker for current and longitudinal assessment of cognitive function, especially in clinical practice.

Background: A common and debilitating challenge experienced by people with TBI is gait-associated mobility impairment and persisting cognitive impairments. Cognitive and physical impairments are often addressed independently during rehabilitation, however, increasing evidence links cognitive and motor processes more closely.Objectives: (1) To determine if correlations exist between measures of cognitive and gait recovery, post-TBI. (2) To investigate the predictive power of cognition at 2-months on gait outcomes at 12-months post-TBI.Methods: In this secondary, longitudinal study of cognitive and neural recovery, data from 93 participants admitted to an inpatient neurorehabilitation program were analyzed. Spatiotemporal gait variables [velocity, step time variability (STV), step length variability (SLV)] were collected along with cognitive variables [Trail Making Test-B (TMT-B), Digit Span-Forward (DS-F)]. Spearman's correlation coefficients were calculated between gait and cognitive variables. Multilinear and step wise regression analyses were calculated to determine predictive value of cognitive variables at 2-months on gait performance at 12-months-post TBI.Results: At 2-months post-injury, TMT-B was significantly correlated with gait velocity and STV; and DS-F was significantly correlated with velocity. At 12-months post-injury, TMT-B and DS-F was still significant correlated with velocity. TMT-B at 2-months was correlated with SLV and STV at 12-months; and DS-F correlated significantly with velocity. Regression models showed TMT-B at 2-months predicting STV, SLV, and velocity at 12-months.Conclusions: Significant associations and predictions between physical and cognitive recovery post-TBI were observed in this study. Future directions may consider a “neural internetwork” model as a salient rehabilitation approach in TBI that integrates physical and cognitive functions.

BACKGROUND: Parkinson disease (PD) is a progressive neurological disease resulting in motor impairments, postural instability, and gait alterations which may result in self-care limitations and loss of mobility reducing quality of life. OBJECTIVE: This study’s purpose was to determine the impact of a community-based boxing program on gait parameters, dual task and backwards walking in individuals with PD. METHODS: This study included 26 community dwelling individuals with PD who participated in 12-week boxing classes (1 hour, 2 times a week). The focus was on upper/lower extremity exercises using punching bags, agility drills, and strengthening activities. Pre/post testing was performed for dual task and gait parameters and was analyzed using t-tests. RESULTS: Analysis of the scores indicated participants performed significantly better at post-test compared to pre-test on self-selected walking velocity (P = 0.041), cadence (P = 0.021); backwards walking velocity (P = 0.003), step length (P = 0.022); dual task walking velocity (P = 0.044), step length (P = 0.023), and gait variability index (P = 0.008). No significant differences for fast walking. CONCLUSIONS: Multi-modal boxing produced improvements in gait velocity, dual task velocity, step length, and gait variability, as well as backwards walking velocity and step length. These improvements may impact independence with functional mobility and may improve safety but require further studies.

Background: Clinical and laboratory assessment of people with mild traumatic brain injury (mTBI) indicate impairments in eye movements. These tests are typically done in a static, seated position. Recently, the use of mobile eye-tracking systems has been proposed to quantify subtle deficits in eye movements and visual sampling during different tasks. However, the impact of mTBI on eye movements during functional tasks such as walking remains unknown.Objective: Evaluate differences in eye-tracking measures collected during gait between healthy controls (HC) and patients in the sub-acute stages of mTBI recovery and to determine if there are associations between eye-tracking measures and gait speed.Methods: Thirty-seven HC participants and 67individuals with mTBI were instructed to walk back and forth over 10-m, at a comfortable self-selected speed. A single 1-min trial was performed. Eye-tracking measures were recorded using a mobile eye-tracking system (head-mounted infra-red Tobbii Pro Glasses 2, 100 Hz, Tobii Technology Inc. VA, United States). Eye-tracking measures included saccadic (frequency, mean and peak velocity, duration and distance) and fixation measurements (frequency and duration). Gait was assessed using six inertial sensors (both feet, sternum, right wrist, lumbar vertebrae and the forehead) and gait velocity was selected as the primary outcome. General linear model was used to compare the groups and association between gait and eye-tracking outcomes were explored using partial correlations.Results: Individuals with mTBI showed significantly reduced saccade frequency (p = 0.016), duration (p = 0.028) and peak velocity (p = 0.032) compared to the HC group. No significant differences between groups were observed for the saccade distance, fixation measures and gait velocity (p &gt; 0.05). A positive correlation was observed between saccade duration and gait velocity only for participants with mTBI (p = 0.025).Conclusion: Findings suggest impaired saccadic eye movement, but not fixations, during walking in individuals with mTBI. These findings have implications in real-world function including return to sport for athletes and return to duty for military service members. Future research should investigate whether or not saccade outcomes are influenced by the time after the trauma and rehabilitation.
