NCT02903823
The goal of this pilot study to determine whether there is a significant therapeutic advantage to place the ITB catheter within the cervical, thoracic or lumbar region of the spine. It is also a goal of this pilot study to determine whether the origin of spasticity influences the effect of Lioresal Intrathecal (baclofen injection) on ITB catheters located in the cervical, thoracic or lumbar regions of the spine. The investigators propose to study the impact of catheter location on the reduction in spasticity within a group of patients who are scheduled for ITB trial.
NCT01547117
Patients with POTS may not adequately expand their plasma volume in response to a high-sodium (Na+) diet. Mechanisms involved in the regulation of plasma volume, such as the renin-angiotensin-aldosterone system and renal dopamine, may be impaired in POTS and may respond inappropriately to changes in dietary sodium.The purpose of this study is to determine (1) whether a high dietary sodium level appropriately expands plasma volume in POTS; (2) whether plasma renin activity and aldosterone are modified appropriately by changes in dietary sodium in POTS; and (3) whether patients with POTS have improvements in their orthostatic tachycardia and symptoms as a result of a high dietary sodium level.
