Maveric Magnetic Resonance Imaging Used to Study Detailed Bone Apposition and Fixation of the Stryker Trident II Tritanium System

The study aims to describe bone apposition and fixation of the Trident and Trident II Tritatnium acetabular system in patients 1 year status post total hip replacement. We will be studying this by comparing magnetic resonance imaging (MRI)s taken 1 year s/p total hip replacement with a Trident II cup with MRI's taken of patients with the Trident Cup who had MRIs done at 1 year post-op.

Trident II Tritanium Acetabular Shell Outcomes Study

The purpose of this study is to review the performance and success rate of an FDA approved cementless hip replacement part called the Trident II Tritanium Acetabular Shell. The study will specifically look at the need to revise the hip replacement after 5 years. This will be compared to how much this happens in patients who have hip replacement with similar cementless acetabular shells.

The purpose of this study is to evaluate a hip implant system used when a previous hip replacement surgery has failed.

Fixation and Stability of the Trident® II Clusterhole HA Shells

The purpose of the Trident® II project is to introduce a cup system that modernizes and streamlines Stryker's acetabular shell portfolio. The Trident® II Clusterhole HA Shell combines the history of Stryker's Trident® shells with plasma spray CpTi with HA coating. Plasma spray coating and HA is considered to be the gold standard in orthopaedics today. This coating will help the cup to achieve early stability and long term fixation. One of the causes for implant failure is l...

Clinical Effect of Massage Chair on Older Adults

The use of massage chairs is becoming more popular in many countries. According to the previous reports, some manual massages have positive effects on the mood, pain, fatigue, and sleep quality. However, the clinical benefits of the massage chair have not been fully understood. In this trial, it is aimed to evaluate the clinical effectiveness of the 6-month regular use of massage chair twice a day. It is hypothesized that long-term regular use of massage chair has positive effe...

A Prospective RSA and Clinical Evaluation of the Trident II Acetabular Cup

The objective of this study is to use radiostereometric analysis (RSA) and clinical outcome measures to evaluate early post-operative implant stability and the clinical performance of Stryker's Trident II Acetabular Cup.

ABC/Trident Ceramic Post Approval Study

The purpose of the Post Approval Study of the ABC and Trident systems is to continue to demonstrate the safety and efficacy of the alumina-on-alumina bearing surfaces combined with the appropriate shell in a cementless application.

How Well Does the 30-Second Chair Stand Test Predict Rehabilitation Needs in Acutely Admitted Elderly Patients

The aims are to identify predictive indicators of hospitalized elderly medical patients' need for rehabilitation and to validate (known group validity) the Chair Stand Test

Measuring the Feasibility and the Effects of Chair Massage on Pain and Discomfort in the Cardiac Sonographer

The purpose of this study is to determine whether the effects of chair massage and/or chair massage with stretching may reduce musculoskeletal pain and discomfort related symptoms associated with the job duties of a cardiac sonographer.

Metal Ion Levels in Stryker Trident II Tritanium System With Modular Dual Mobility (MDM) Liner, Ceramic Head, and SecurFit Advanced Stems

Metal Ions levels of cobalt, chromium, and titanium in 40 patients preoperatively and at least 1 year status post total hip replacement with the Trident II Tritatnium system using an MDM liner and ceramic head. Are cobalt, chromium, and titanium levels in patients who undergo a total hip replacement with a Trident II Tritanium system, MDM liner, and ceramic head normal one year after surgery? Investigators expect to find normal levels of metal ions (cobalt, chromium, and titani...

ATTUNE TM Video-fluoroscopy Study

The proposed study is a retrospective, observational study. A group of 5 subjects with the AttuneTM cruciate retaining (CR) fixed bearing total knee arthroplasty (TKA) are analysed during level walking, a deep knee bend, sitting down onto a chair, standing up from a chair and stair descent at least 12 months post-operatively, in terms of 3D fluoroscopic assessed tibio-femoral TKA motion as well as simultaneous skin marker assessed whole leg motion and ground reaction forces. Th...

Efficacy of a Mechanical Chair for Treatment of Benign Paroxysmal Positional Vertigo (BPPV)

Benign paroxysmal positional vertigo (BPPV) is the most common inner ear cause of dizziness. It has been reported that up to 900 of every 10,000 people in the United States experience this problem with an estimated annual healthcare cost approaching $2 Billion. This problem occurs when calcium carbonate "crystals" which are present and needed in one part of the balance area of the inner ear become displaced to a different part of the balance area. This is very disruptive to the...

Chairless Chair Exoskeleton. Work-physiological-biomechanical Analysis of the Lower Extremities

Standing work is associated with increased risks of venous and musculoskeletal disorders; particularly low back pain is commonly reported in prolonged standing work. In manufacturing work, workstations often do not allow standing aids due to insufficient functional and spatial conditions. In 2014, the car manufacturer Audi introduced the lower leg exoskeleton developed by Noonee to their employees working in the factories. This exoskeleton, the 'Chairless Chair' has the advanta...

Different Treatments With the TRV Reposition Chair

To investigate which treatment option (reposition maneuver) with the TRV chair that is the most effective in patients diagnosed with benign paroxysmal positional vertigo (BPPV). Subtypes of BPPV will be examined after randomization to specific treatments.

To determine if sitting in a chair or sitting on the floor lends itself to better posture while playing video games.

3 Minutes Chair Rise Test (3CRT) in Patients With COPD

Improvement in the functional functioning and dyspnea of COPD patients after a rehabilitation program (RHB) is assessed by exercise tests and questionnaires difficult to replicate outside specialized centers. In order to monitor the eventual decline of patients in the course of their RHB management, Chair Rise Tests (3CRT-1CRT-5STS) and short questionnaires were developed (CAT-DIRECT). The goal of this prospective, multicenter, real-life study is to compare the change in sever...

Prospective Evaluation of Cognitive Outcomes After Anesthesia on Patients in the Beach Chair Position

Functional Evaluation of the Total Knee Prostheses:Rising From a Chair

In this study, a functional evaluation of total knee arthroplasty (TKA) patients is performed. The patients are measured prior to surgery and 6 and 12 months after surgery. The measurements consist of questionnaires and rising from a chair. Also, two types of TKA are functionally evaluated. At last, the TKA group will be compared to a THP group.
