Filter by:The primary objective is to determine the tolerability and efficacy of a low-dose ketamine infusion for the treatment of Levodopa-Induced dyskinesias (LID), both acutely and during post-infusion evaluation (week 2-6), as measured by a change in patient diaries of dyskinesia and the UDysRS. Secondary objectives include observing the effects of ketamine on various symptoms of Parkinson's disease and Levodopa side effects. This includes the duration of "off," "on without dyskinesia," and "troublesome dyskinesia" time during waking hours, effects on chronic and acute pain, quality of life, and other general PD symptoms as noted in the Unified Parkinson's Disease Rating Scale. There is no highly effective treatment for levodopa-induced dyskinesia. This research study will use intermittent infusions of ketamine, on 10 volunteer subjects, which could provide significant improvement in dyskinesia utilizing a novel mechanism of action compared to current treatment strategies. Positive results in this study could lead to new novel treatments for dyskinesia and further development for other PD symptoms such as depression and pain.
Scapular dyskinesis (SD) is common in overhead athletes and negatively influence the athletes' performance, increasing the risk of shoulder injury. The kinetic chain (KC) exercises for SD rehabilitation that emphasize importance of core strength and scapula stability during skillful performance. Ai Chi, the aquatic exercises performed in functional positions, which are adequate for power transfer of KC. This study will investigate the effect of KC-based water exercises, Ai Chi, on scapular muscles in overhead athletes with SD.
Parkinson' patients who have not had dyskinesia would be observed for 2 years in a multicenter prospective study with the purposes to clarify the predicting factors of dyskinesia.
This is a new gene discovery program for individuals with PCD who do not have a specific genetic etiology identified. Research procedures involve a single blood draw from the affected individual and from unaffected family members in an effort to identify new genetic targets.
Using routinely collected clinical data, this study aims to quantify intra-individual (i.e. in the same individual) variations between measurements of lung function in stable patients with primary ciliary dyskinesia (PCD), a rare genetic disease that causes lung damage.
Evaluate the safety and efficacy of unilateral focused ultrasound pallidotomy using the ExAblate 4000 System in the management of dyskinesia symptoms or motor fluctuations for medication refractory, advanced idiopathic Parkinson's disease.
Scalp acupuncture formed by combining traditional Chinese acupuncture techniques and modern theories in medical anatomy has been widely used to treat ischemic stroke in China, but effective clinical trials that verify its efficacy are lacking. This study proposes to verify the effects of Lu's scalp acupuncture on ischemic stroke by comparing differential improvement of motor function between conventional rehabilitation alone and conventional rehabilitation with Lu's scalp acupuncture.
The proposed study is to evaluate the effectiveness of ExAblate Transcranial MRgFUS as a tool for creating a unilateral lesion in the Vim thalamus or the globus pallidus (GPi) in patients with treatment-refractory symptoms of movement disorders.
Presently no generally effective treatments for tardive dyskinesia (TD) are available. D-serine is a naturally occurring amino acid that acts in-vivo as positive allosteric modulator at the glycine site associated with the glutamatergic NMDA receptor. Previous studies have suggested that D-serine may improve motor symptoms, including dyskinesias, which are caused by treatment with presently used antipsychotics drugs. The hypothesis under investigation in the present study is that D-serine adjuvant treatment may improve TD in schizophrenia patients diagnosed with this disorder.
Levodopa-induced dyskinesias have been associated with irregular oscillatory discharge characteristics of basal ganglia. From the other hand, LEV which shares a different electrophysiologic profile than other antiepileptics, inhibits hyper-synchronization of abnormal neuronal firing in experimental models of epilepsy. LEV also reduces levodopa-induced dyskinesias in MPTP-lesioned macaques and modulates "priming phenomenon" which associated with long-term changes in synaptic function that can lead to dyskinesias in PD. Study objectives : - To evaluate the effects of levetiracetam (LEV) in two doses (500 and 1000mg) vs placebo on disabling dyskinesias that develop as result of long-term treatment with levodopa, occurring at the time of maximal clinical improvement in patients with Parkinson's disease (PD). - To evaluate the safety of LEV in patients with PD and antiparkinsonian medication.
