Filter by:Movement screening tests to identify deficits or poor movement quality is commonly used in soccer and other sports to assess injury, to evaluate rehabilitation goals and return to sport after injury. Female soccer players have an increased risk of suffering a knee injury which can be related to a poor knee control. Knee control can be observed and assessed by the Single Leg Squat (SLS) test. The SLS test is reported to be reliable, but there still is an overall lack of clear evidence of the accuracy for tests used for assessing movement quality in sports medicine, and the discriminate and predictive validity of the SLS test in a female soccer cohort needs to be further investigated. It is also not clear what significance other physiological- psychosocial- and hormonal factors have for the outcome of the SLS and for injury. The overall aim of this project is to investigate if the outcome of a visually assessed SLS test can discriminate between individuals with a previous injury in the lower extremity, and if the outcome, separate or together with physiological-, psychosocial- and hormonal factors can predict future injury in a cohort of female soccer players. The authors hypothesises that the outcome of the SLS cannot discriminate between individuals with a previous injury in the lower extremity but that the outcome of the SLS, separate or together with physiological-, psychosocial- and hormonal factors can predict future injury in a cohort of female soccer players. 269 female soccer players (≥16 Yr.) from Damallsvenskan, Elitettan and division 1 in the area of Stockholm was enrolled in the study and baseline measurements were done during 2022-01-08 to 2022-02-21. The female soccer cohort will be followed during the season 2022 regarding injuries upcoming injuries.
The purpose of this study is conduct a pilot open trial of a web-based cognitive bias modification intervention to reduce anxiety symptoms in persons with Huntington's disease and persons with Parkinson's disease.
Vibration applied to the skin has been anecdotally reported to potentially improve motor control in patients with movement disorders including Parkinson's disease, however few devices have been studied formally. In this study, the investigators will test the effect of skin surface vibration applied non-invasively to patients with movement disorders to determine if there are any beneficial effects on common tasks of motor control and/or abnormal motor symptoms in patients with Parkinson's disease (PD), essential tremor (ET), and dystonia.
Bradykinesia is a key parkinsonian feature yet subjectively assessed by the MDS-UPDRS score, making reproducible measurements and follow-up challenging. In a Movement Disorder Unit, the investigators acquired a large database of videos showing parkinsonian patients performing Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) part III protocols. Using a Deep Learning approach on these videos, the investigators aimed to develop a tool to compute an objective score of bradykinesia from the three upper limb tests described in the Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) part III.
Diagnosing Parkinson's disease (PD) depends on the clinical history of the patient and the patient's response to specific treatments such as levodopa. Unfortunately, a definitive diagnosis of PD is still limited to post-mortem evaluation of brain tissues. Furthermore, diagnosis of idiopathic PD is even more challenging because symptoms of PD overlap with symptoms of other conditions such as essential tremor (ET) or Parkinsonian syndromes (PSs) such as progressive supranuclear palsy (PSP), multiple system atrophy (MSA), corticobasal degeneration (CBD), or vascular Parkinsonism (VaP). Based on the principle that PD and PSs affect brain areas involved in eye movement control, this trial will utilize a platform that records complex eye movements and use a proprietary algorithm to characterize PSs. Preliminary data demonstrate that by monitoring oculomotor alterations, the process can assign PD-specific oculomotor patterns, which have the potential to serve as a diagnostic tool for PD. This study will evaluate capabilities of the process and its ability to differentiate PD from other PSs with statistical significance. The specific aims of this proposal are: To optimize the detection and analysis algorithms, and then to evaluate the process against neurological diagnoses of PD patients in a clinical study.
Ischemic stroke is a major public health issue, likely to cause functional disability. It is well known that sleep has an impact on brain plasticity, and after an ischemic stroke, studies have shown subjective sleep quality alterations and sleep architecture abnormalities. Furthermore, there is no clear guideline showing the usefulness of a systematic sleep investigation following an ischemic stroke. The aim of the study is to identify retrospectively correlation between polysomnographic abnormalities (sleep apnea, periodic limb movements, disturbed sleep architecture…) and functional recovery after an ischemic stroke. The study also assesses the impact of sleep abnormalities on survival, and the risk of new cardiovascular event.
Parkinson's disease and essential tremor are chronic movement disorders for which there is no cure. When medication is no longer effective, deep brain stimulation (DBS) is recommended. Standard DBS is a neuromodulation method that uses a simple monophasic pulse, delivered from an electrode to stimulate neurons in a target brain area. This monophasic pulse spreads out from the electrode creating a broad, electric field that stimulates a large neural population. This can often effectively reduce motor symptoms. However, many DBS patients experience side effects - caused by stimulation of non-target neurons - and suboptimal symptom control - caused by inadequate stimulation of the correct neural target. The ability to carefully manipulate the stimulating electric field to target specific neural subpopulations could solve these problems and improve patient outcomes. The use of complex pulse shapes, specifically biphasic pulses and asymmetric pre-pulses, can control the temporal properties of the stimulation field. Evidence suggests that temporal manipulations of the stimulation field can exploit biophysical differences in neurons to target specific subpopulations. Therefore, our aim is to evaluate the effectiveness of complex pulse shapes to reduce side effects and improve symptom control in DBS movement patients.

Evidence suggests that temporal manipulations of the stimulation field can exploit biophysical differences in neurons to target specific subpopulations. Therefore, our aim is to evaluate the direct neurophysiological effects of complex pulse shapes in DBS movement disorder patients. This will be achieved using a two-stage investigation: stage one will study the neural response to different pulse shapes using electroencephalography (EEG) recordings. Stage two will study the neural responses to different pulse shapes using intra-operative local field potential (LFP) recordings. This study only relates only to the collection of EEG and LFP recordings in DBS patients. The protocol does not cover any surgical procedures, which already take place as part of the patient's normal clinical care.
The technological advance of magnetic resonance-guided focused ultrasound (MRgFUS) has once again brought lesion therapy back to the clinical frontline for the treatment of movement disorder. Thus far, the safety of MRgFUS has been widely proven and has just been made available in China in late 2020. We attempted to analyze the neuroplasticity characteristics and altered neural circuit activity in patients subjected with MRgFUS thalamotomy via post-hoc retrospective analysis of archived MR imaging in our site, and to explore potential biomarkers that could be used to predict the treatment outcome.
