Tekscan pressure sensors are used in biomechanics research to measure joint contact loads. While the overall accuracy of these has been reported previously, effects different calibration algorithms on sensor have not compared. The objectives this validation study were determine most appropriate method supplied program software and compare its obtained with two user-defined protocols. We evaluated accuracies for test loads within low range, high full range sensor. Our experimental setup...
Currently, none of the commercially available rehabilitation robots are widely distributed among individuals with limited use their arms and hands. Market success requires design that achieves an acceptable tradeoff between function, appearance, ease use, reliability, cost. User defined task priorities imperative consideration within as devices which fail a user's functionality requirement will never succeed in market place. Consequently, this article reviews nine different priority surveys...
Describes research work directed towards the development and application of a design methodology to determine optimal configuration powered upper-limb orthosis. The objective was minimize orthosis complexity, defined as number degrees freedom, while maintaining ability perform specific tasks. This achieved in three stages. First, potential users were interviewed their priority Secondly, natural arm motions able-bodied individuals performing tasks profiled using video tracking system....
Femoral neck fracture is the most common short-term concern after hip resurfacing arthroplasty. Currently, there little basis to decide between neutral and valgus placement. We loaded 10 notched cadaveric femur pairs failure; one side was implanted at 0° relative femoral other 10° valgus. All 20 were dual-energy xray absorptiometry-scanned. Failure load correlated with bone mineral density. Valgus placement increased by an average of 28% over for specimens normal density but had no effect on...
The management of the patellar articular surface at time primary total knee arthroplasty (TKA) is controversial. We used expected-value decision analysis to determine whether patella should be resurfaced in TKA, and also secondary resurfacing on an unresurfaced worthwhile. Outcome probabilities utility values were derived from randomized controlled trials only. A tree was constructed fold-back performed ascertain best treatment path. Sensitivity analyses effect decision-making varying...
Glenohumeral contact forces have only been calculated previously either for simple abduction or athletic activities. The objective of this study was to determine the glenohumeral tasks which are demanding shoulder but would commonly be performed by older people. functional chosen were using arms stand up from and sit down into a chair, walking with cane, lifting 5 kg box height both hands, 10 suitcase. trunk angles, arm angles hand loads six healthy subjects, average age 55 years, recorded....
Total knee arthroplasty (TKA) changes the joint in both intentional and unintentional, known unknown, ways. Patellofemoral tibiofemoral kinematics play an important role postoperative pain, function, satisfaction revision, yet are largely unknown. Preoperative kinematics, or may help identify causes of poor clinical outcome. challenging to record since patella is obscured by metal femoral component X-ray moves under skin. The purpose this study was determine kinematic degrees freedom having...
Fixation failure of glenoid components is the main cause unsuccessful total shoulder arthroplasties. The characteristics these failures are still not well understood, hence, attempts at improving implant fixation somewhat blind and rate remains high. This lack understanding largely due to fundamental problem that direct observations impossible as inherently embedded within bone. Twenty custom made implants, reflecting various common designs, a specimen set-up was prepared enable observation...
Objectives Numerous complications following total knee replacement (TKR) relate to the patellofemoral (PF) joint, including pain and patellar maltracking, yet options for in vivo imaging of PF joint are limited, especially after TKR. We propose a novel sequential biplane radiological method that permits accurate tracking tibiofemoral (TF) joints throughout range movement under weightbearing, test it knees pre- post-arthroplasty. Methods A three with end-stage osteoarthritis had undergone TKR...
Patellar maltracking after total knee arthroplasty often results in complications, including anterior pain, instability and impingement, is therefore better resolved intraoperatively. Many factors can affect patellar kinematics during replacement, component position, implant design, joint alignment, soft tissue tensions. However, to our knowledge, the impact of on has not been previously reported vivo. A computer-assisted surgery (CAS) system was developed measure pre-arthroplasty...
