Feasibility of a Person-centred Digital Program Targeting Physical Activity in Spinal Stenosis Surgery...

Spinal Stenosis Lumbar

Spinal stenosis is the most common cause of degenerative spinal surgery. The majority do not achieve the global recommendations for health-promoting physical activity before or after surgery. Patients with a low level of physical activity and a high degree of fear of movement are at an increased risk of poorer health outcomes after surgery. Increasing the number of steps per day is a way to increase physical activity, which in long term can lead to health benefits. In addition, a digital format is a way to increase the availability of physiotherapy to strive for equal rehabilitation. The overall purpose of the research project is to improve health outcome and increase the availability of rehabilitation for patients at high risk of negative health outcomes after spinal surgery due to spinal stenosis through Get Back, a person-centered and digital program with a focus on physical activity. Before conducting a large-scale study, the investigators want to conduct a study that aims to investigate and develop the Get Back program regarding content and dose, treatment fidelity as well as feasibility in terms of study procedure, compliance, and acceptability. Approximately thirty patients with lumbar spinal stenosis and an identified risk profile for poorer postoperative outcomes will be recruited from two spine clinics in Sweden. The program involves meeting a physiotherapist digitally (through video call) approximately 1 week before surgery to formulate a person-centered health plan. The health plan is monitored and progressed by the physiotherapist by video until eleven weeks after surgery. The Get Back program includes 5 sessions (1 hour each) which are supplemented with 5 booster sessions (30 minutes) to reinforce the intervention. Get Back is based on three key components that run through all sessions. These are person-centeredness, behavioral medicine techniques to reduce fear of movement and worries about pain, as well as to optimize physical activity. The physiotherapist supports the participant's individual resources and abilities through validated behavioral medicine methods in combination with education/communication/knowledge support and behavior-strengthening tools (which are also used in-between sessions) to achieve the participant's personal goals linked to physical functioning, physical activity, and health. The program will be compared to standard physiotherapy.

Asymptomatic Carotid Stenosis and Mobility Function With Exercise Intervention

Asymptomatic Carotid Stenosis (50-69%)Mobility Impairment

Moderate (50-69%) asymptomatic carotid artery stenosis (ACAS) is an important and under-appreciated contributor to balance and mobility dysfunction. This is significant because declines in balance and mobility are a significant predictor of falls, disability, loss of independence, and death in older adults. Further, falls and fall-related injuries in older adults cost approximately 50 billion dollars annually in the United States, and are the leading cause of adverse events reported by the Veterans Health Administration. This proposal seeks to: 1) investigate the impact of a supervised aerobic and challenging balance exercise program on balance and mobility function in patients with moderate ACAS; and 2) elucidate whether these changes are related to changes in cerebral perfusion. With 830,000 Veterans estimated to have moderate ACAS and at risk for balance and mobility dysfunction and increased falls, the findings from this study could have significant impacts on the clinical management, quality of life, and functional independence of Veterans with moderate ACAS.

Investigation of the ALLEGRA THV System With a New Delivery System in Patients With Aortic Stenosis...

Transcatheter Aortic Valve Implantation

The EMPIRE study confirms the technical performance of the new IMPERIA Delivery System and evaluates the safety and efficacy of the entire ALLEGRA THV System. The primary endpoint is device success rate at 7 days (discharge from index procedure or 7 days post implant, whichever comes first), as defined by VARC 2. Based on the outcomes of a study with a similar device and considering a drop-out rate of 5%, 107 patients need to be enrolled in the study.

TCM Conservative Treatment for the Degenerative Lumbar Spinal Stenosis

Degenerative Lumbar Spinal Stenosis

Lumbar degenerative disease is a common disease develops into degenerative lumbar spinal stenosis(DLSS)in the elderly and eventually. The long course of disease and other characteristics determine that conservative treatment cannot be effective in a short time, surgery is recommended to relieve symptoms quickly. However, the incidence of complications and disease recurrence rate after surgical treatment is high, and the reoperation rate is as high as 30-50%. Conservative treatment has the advantages of low price and high acceptance, so the treatment strategy first returns to conservative treatment.The complexity and repeatability of DLSS are the main reasons for the adoption of comprehensive treatment in modern medicine, but the efficacy is not significant. Traditional Chinese medicine (TCM) has its own theories and various methods to treat low back pain.

Colibri Transcatheter Aortic Heart Valve System Study

Severe Aortic Stenosis

The Colibri Heart Valve clinical investigation ("COL-01") is a prospective, multicenter, exploratory single arm and controlled clinical investigation compared to recent historical results. This study will be conducted in about 7 European sites. The study will evaluate the safety and performance of the Colibri Transcatheter Aortic Heart Valve System for the treatment of symptomatic severe aortic stenosis via transfemoral access in high surgical risk patients. 30 subjects suffering from symptomatic severe aortic tricuspid valve stenosis and who are at high surgical risk (logistic EuroSCORE I > 20% or other risk factors not included in this score such as frailty, porcelain aorta, sequelae of chest radiation or logistic EuroSCORE I < 20% but considered at high risk by local Heart Team evaluation) will be enrolled in this clinical investigation. The primary objective of this clinical investigation is to evaluate the all-cause mortality at 30 days post implantation. The secondary objectives are to evaluate the safety and performance of the investigational device at 30 days, 6 and 12 months, and 2, 3, 4, 5 years post implantation.

Feasibility of Prehab for Lumbar Spinal Stenosis

Lumbar Spinal StenosisPrehabilitation

The literature has shown evidence of the effectiveness of prehabilitation programs on post-operative recovery for musculoskeletal conditions; however, evidence for prehabilitation for lumbar spinal stenosis (LSS) is limited. Investigators have found that there is very low to low quality evidence for the effect of prehabilitation interventions for improving outcomes following lumbar spine surgery. Therefore, the purpose of this study will be to determine the feasibility of a prehabilitation program for patients undergoing LSS surgery, and pilot test the protocol to provide the foundation for future design of a larger, multicenter randomized controlled trial.
