Condition: Stroke
Investigator: Joel Stein, MD
Status: Currently Recruiting
My Hand Project for Stroke Patients: We are testing a robotic device to help people who had a stroke use their weak hand more easily. This research study would involve you wearing a hand robot that helps open and close your fingers in order to use your hand to pick up common everyday objects. During the study, you may be asked to try out different…
Condition: Surgery
Investigator: Bret Taback, MD
Status: Closed
The purpose of this study is to test an investigational device called the Echopulse for treatment of breast fibroadenomas in women. Fibroadenomas are benign (noncancerous) breast tumors. These lumps can occur alone, in groups, or as a complex of lumps together. Sometimes women feel these in the breast when doing regular self-breast exams, or they may be…

This program aims to help improve adult caregivers of stroke survivors ability to care for their stroke survivors with their daily needs. Each session will cover different topics which are important for caregivers to understand in order to best engage in their new role. Topics will include, but are not limited to: bathing, toileting, dressing, transfers,…
Condition: Stroke
Investigator: Dawn Nilsen, EdD, OTR/L, FAOTA
Status: Closed
The purpose of this research is to learn about types of practice that may benefit stroke survivors when learning to use their weaker arm to perform a task. Potential participants will be asked to come to Columbia University Irving Medical Center (CUIMC) for a screening session. Eligible participants will be randomized into two groups with different practice…
Condition: Surgery
Investigator: Marcos Vidal Melo, MD, PhD
Status: Closed
We are asking you to participate in a research study to learn if different ways of doing routine anesthesia and patient care before, during and after abdominal surgery can reduce breathing problems. The total time of the study is 3 months with daily visits by a member of our study team while you are in the hospital and 3 short follow-up calls after you…
Condition: Psychiatric Disorders / Schizophrenia
Investigator: Gaurav Patel, MD, PhD
Status: Closed
Our lab is conducting a series of research studies that investigate how specific brain regions are related to functioning in work, school, and in other social situations. As a study participant, you will be asked to complete clinical and neuropsychological assessments, an eye-tracking task, and a non-invasive MRI scan. Study participants earn between $15-50…
Condition: Stroke
Investigator: Joel Stein, MD
Status: Closed
Stroke often results in limitation of arm movements, from which many people do not fully recover. We believe that early and intensive therapy is important to enhance recovery of arm movements after stroke. We are doing this research study to see how much arm movements improve with intensive therapy in patients have had a stroke in the past 5 weeks. We will…
Condition: Surgery
Investigator: Michael Argenziano, MD, FACS
Status: Closed
Thepurposeof the study is to test whether or not QPI-1002 could be used to lessen or prevent acute kidney injury after heart surgery. Another purpose is to better understand the safety of QPI-1002.
Condition: Surgery
Investigator: Jeffrey Geller, MD
Status: Closed
The purpose of this study is to evaluate the short-term (1 year) and long-term (5 and 10 year) safetyand effectiveness of the JOURNEY II CR Total Knee System in patients with degenerative joint disease of the knee requiring primary total knee replacement. Clinical, radiographic, and health economic outcomes will be evaluated.
Condition: Psychiatric Disorders / Schizophrenia
Investigator: Jeffrey Lieberman, MD
Status: Closed
This study plans to learn more about an investigational new drug called lumateperone tosylate (ITI-007) and may help us find new types of treatment for schizophrenia and schizoaffective disorder.
Condition: Psychiatric Disorders / Schizophrenia
Investigator: Joshua Kantrowitz, Md
Status: Closed
The purpose of this study is to determine whether the brain wave patterns are improved after administration of CVN058 compared to placebo in subjects with schizophrenia. The study uses electroencephalography (EEG) to measure naturally occurring brain waves as you listen to recorded sounds.
Condition: Surgery
Investigator: Nicholas Morrissey, MD
Status: Closed
You are being asked to be part of this study because you have been diagnosed with a bulge or aneurysm in your iliac arteries, the vessels that supply blood to the lower half of your body. As an aneurysm expands, the walls become weak and may rupture, causing a major loss of blood with a high risk of death and other serious complications. To avoid this risk…
