Additionally, this study will evaluate how deficits in visual attention are associated with freezing of gait (FOG) in Parkinson's disease. There is currently no reliable treatment for FOG and little is understood about the underlying reason this occurs. Some recent research has found that stimulating the right side of the brain seems to improve FOG. The right side of the brain is also paramount for visual attention, which is why investigators are conducting this study.",[26,27,28],"Parkinson Disease","Gait Disorders, Neurologic","Visuospatial\u002FPerceptual Abilities",[30,31,32,33],"Freezing of gait","Subthalamic nucleus","Visuospatial attention","Deep brain stimulation","RECRUITING","2025-05-20",{"date":37,"type":38},"2025-05-29","ACTUAL",{"date":40,"type":38},"2025-04-01",{"date":42,"type":20},"2026-06",{"name":44,"class":45},"Medical University of South Carolina","OTHER",1,{"id":48,"slug":49,"hasResults":11,"nctId":50,"briefTitle":51,"officialTitle":52,"acronym":4,"eligibilityCriteria":53,"healthyVolunteers":54,"sex":16,"minAge":17,"maxAge":55,"enrollmentInfo":56,"targetDuration":58,"studyType":59,"phases":4,"briefSummary":60,"conditions":61,"keywords":68,"overallStatus":72,"whyStopped":4,"lastUpdateSubmitDate":73,"lastUpdatePostDateStruct":74,"startDateStruct":76,"completionDateStruct":78,"leadSponsor":80,"locationsCount":4},"100591815","3-dimensional-evaluation-of-body-perception-100591815","NCT06985329","3-Dimensional Evaluation of Body Perception","Evaluation of Neurocognitive Skills, VisuoSpatial Perception and Perspective Perception in Amputees","Inclusion criteria for the amputee group:\n\n* Acquired amputees\n* Aged 18-65 years\n* Using a prosthesis for at least six months\n* At least a primary school graduate\n* Individuals who can adapt to prolonged, attention-demanding activities will be included.\n* Standardised Mini Mental State Examination score of \\>24.\n\nFollowing the recruitment of the amputee group, a healthy control group will be recruited to match it in terms of age, gender and educational status.\n\nInclusion criteria for the healthy control group:\n\n* Age range: 18-65 years\n* At least a primary school graduate\n* Individuals who can adapt to prolonged, attention-demanding activities will be included.\n* Standardised Mini Mental State Examination score of \\>24.\n\nExclusion criteria for the amputee group:\n\n* Individuals with congenital amputation\n* Those with phantom limb pain and\u002For sensation\n* Those with an open wound on the stump\n* Bilateral amputation\n* Any neurological or psychiatric diagnosis\n* Those using sedative medication and\u002For its derivatives\n* Have vision and related problems\n* Individuals who are illiterate\n* Individuals participating in treatments targeting body representation (e.g. imagery-based treatments or progressive motor visualisation) will not be included in the study.\n\nExclusion criteria for the Healthy Control Group:\n\n* Having any neurological or psychiatric diagnosis\n* Using sedative medication and\u002For its derivatives\n* People with vision and related problems\n* Illiterate individuals will not be included in the study.",true,"65 Years",{"count":57,"type":20},60,"15 Days","OBSERVATIONAL","The goal of this observational study is to evaluate the changing body perception of amputees aged 18-65 years using prostheses through different personal perspectives of the right-left distinction. In addition, we aimed to examine the relationship between possible changes in body perception and visual spatial perception and neurocognitive performances. The main questions that this study aimed to answer are as follows:\n\n1. Is there a difference between the amputee group and the control group in terms of parameters related to body perception?\n2. Is there a difference between the amputee group and the control group in terms of neurocognitive skills?\n3. Is there any difference between the amputee group and the control group in terms of visual spatial perception abilities?\n\nTo examine whether changes in body perception in amputees affect neurocognitive performance, visuospatial perception and perspective perception and the relationship between them will be compared with a healthy control group.\n\nThe assessments to be applied to both groups can be summarised as follows:\n\n* Demographic information such as age, gender, and education level will be recorded.\n* Mini-mental state test will be used to assess the cognitive level.\n* Edinburgh Handedness Scale will be used to determine the dominant side.\n* Right-left discrimination and personal perspective perception will be assessed using a desktop programme.\n* The clock drawing test and Benton line orientation test will be used to visual spatial perception.\n* A computer based program called The Central Nervous System (CNS) Vital Signs Neurocognitive Test Battery will be used to asesses neurocognitive abilities.",[62,63,64,28,65,66,67],"Body Image","Cognition","Decision Making","Neurocognitive Function","Executive Function (Cognition)","Amputation",[62,63,69,67,70,64,71],"Neuropsychological Test","Executive Function","Visuospatial Skills","NOT_YET_RECRUITING","2025-05-14",{"date":75,"type":38},"2025-05-22",{"date":77,"type":20},"2025-06",{"date":79,"type":20},"2026-06-15",{"name":81,"class":45},"Trakya University"]
