OBJECTIVE Early rehabilitation is effective in an array of acute neurological disorders but it is not established as part of treatment guidelines after aneurysmal subarachnoid hemorrhage (aSAH). This may in part be due to the fear of aggravating the development of cerebral vasospasm, which is the most feared complication of aSAH. The aim of this study was to evaluate the effect of early rehabilitation and mobilization on complications during the acute phase and within 90 days after aSAH. METHODS This was a prospective, interventional study that included patients with aSAH at the neuro-intermediate ward after aneurysm repair. The control group received standard treatment, whereas the early rehab group underwent early rehabilitation and mobilization in addition to standard treatment. Clinical and radiological characteristics of patients with aSAH, progression in mobilization, and treatment variables were registered. The frequency and severity of cerebral vasospasm, cerebral infarction acquired in conjunction with the aSAH, and acute and chronic hydrocephalus, as well as pulmonary and thromboembolic complications, were compared between the 2 groups. RESULTS Clinical and radiological characteristics of patients with aSAH were similar between the groups. The early rehab group was mobilized beginning on the first day after aneurysm repair. The significantly quicker and higher degree of mobilization in the early rehab group did not increase complications. Clinical cerebral vasospasm was not as frequent in the early rehab group and it also tended to be less severe. Each step of mobilization achieved during the first 4 days after aneurysm repair reduced the risk of severe vasospasm by 30%. Acute and chronic hydrocephalus were similar in both groups, but there was a tendency toward earlier shunt implantation among patients in the control group. Pulmonary infections, thromboembolic events, and death before discharge or within 90 days after the ictus were similar between the 2 groups. CONCLUSIONS Early rehabilitation of patients after aSAH is safe and feasible. The earlier and higher degree of mobilization does not increase neurosurgical complications. Rather, the frequency and severity of cerebral vasospasm following aSAH are alleviated and are not aggravated by early rehabilitation.

We conducted a randomized, controlled trial to prospectively confirm that ultrasound-directed transbronchial needle aspiration (USTBNA) results in: (1) improved sensitivity for detecting lymph nodes involved with neoplasm, and (2) a decreased number of aspirates needed to achieve a diagnosis as compared with standard transbronchial needle aspiration (TBNA). The study was conducted in a tertiary medical center on patients undergoing fiberoptic bronchoscopy in the evaluation of enlarged mediastinal lymph nodes. USTBNA or TBNA were followed by rapid, on-site cytopathology examination of the collected specimens. Measurements included the (1) age and sex of the patient, prior diagnosis of cancer, nodal short-axis diameter and node location as determined by computerized tomography (CT), and endobronchial abnormalities at bronchoscopy; (2) number, order, and location of transbronchial aspirates and results of on-site evaluation; (3) results of surgical exploration in patients with negative transbronchial needle aspiration; (4) sensitivity, specificity, and diagnostic accuracy of USTBNA and TBNA; (5) number of aspirates required for successful lymph node aspiration as well as for a diagnosis of cancer for both USTBNA and TBNA; and (6) multiple logistic regression analysis to determine the significance of combinations of clinical predictors and needle aspirate results. Eighty-two bronchoscopic examinations were performed on 80 patients. We found no significant difference between USTBNA and TBNA in sensitivity (82.6% versus 90.5%, respectively), specificity (100% for both), or diagnostic accuracy (86.7% versus 91.7%, respectively). The sensitivity, specificity, and diagnostic accuracy of USTBNA and TBNA were similarly high, regardless of node location (paratracheal or subcarinal). A decrease in the number of aspirates required for lymph node sampling approached statistical significance for all USTBNAs as compared with TBNAs (2.03 +/- 0.19 versus 2.62 +/- 0.25, p = 0.06), but this was not demonstrated for the number required to confirm cancer (1.95 +/- 0.47 versus 2.68 +/- 0.21, p = 0.17). The number of aspirates to successful lymph node aspiration decreased with USTBNA versus TBNA in paratracheal lymph nodes (2.00 +/- 0.20 versus 2.91 +/- 0.34, p = 0.03), but not to a diagnosis of cancer (1.93 +/- 0.25 versus 3.00 +/- 0.58, p = 0.11). No difference was seen in the number of aspirates for subcarinal nodes. The number of TBNA attempts for paratracheal lymph node sampling was inversely correlated with node size (r = 0.48, p = 0.02). No such relation was seen with USTBNA of paratracheal nodes (r = 0.09, p = 0.66), TBNA of subcarinal nodes, or USTBNA of subcarinal nodes. A similar relation was seen between the number of aspirates to a diagnosis of cancer. On multiple logistic regression analysis, a positive transbronchial aspirate was associated only with a larger lymph node and history of prior cancer. We conclude that: (1) in the setting of on-site cytopathology, transbronchial needle aspiration has a high sensitivity, specif...
This study provides Class I evidence that for patients with upper extremity motor impairment after stroke, compared to conventional training, VR training did not lead to significant differences in upper extremity function improvement.
