In Brief Safe knee function under all real-world conditions is a crucial factor in the prescription of specific prosthetic mechanisms. Although many amputees have reported subjective belief that electronic C-Leg combines increased while walking with safety, till date there has been little objective evidence to support this claim. This study was designed identify biomechanical differences would permit evaluation relative safety critical situations different joint designs. gait laboratory,...

The biomechanical effectiveness of a valgus-inducing knee brace was investigated for 16 patients with osteoarthritis (mean +/- standard deviation age 56 10 yr, height 172 9 cm, mass 83 7 kg, body index 27.6 4.5 kg/m(2)). At the time investigation, all subjects had been wearing at least 4 weeks. In addition to conducting gait analysis, we calculated valgus moment generated by using novel system that measured actual deformation during stance phase and determined reaction force created on leg....

Previous studies have shown low end-user acceptance of a hip disarticulation style prosthesis and that the limitations such prostheses, including poor gait pattern, socket discomfort, weight prosthesis, loss mobility, instability high energy consumption are contributing factor. This study was initiated to determine if new prosthetic joint could help overcome some concerning pattern. The present analyzed pattern six amputee subjects. objective compare two different joints, both from Otto Bock...

A new static alignment method for trans-tibial prostheses is suggested using the individual load line as a reference. Standing posture and of 18 experienced prosthetic users with good walking ability were determined compared 20 healthy persons. The was defined by means Otto Bock system "L.A.S.A.R. Posture". sagittal standing amputees non-amputees differs. Normally only prosthesis worn amputee dynamically aligned over an extended period time satisfies biomechanical rules alignment. In...

Climbing stairs can pose a major challenge for above-knee amputees as result of compromised motor performance and limitations to prosthetic design. A new, innovative microprocessor-controlled knee joint, the Genium, incorporates function that allows an amputee climb step over step. To execute this function, number different sensors complex switching algorithms were integrated into joint. The is intuitive user. biomechanical study was conducted assess objective gait measurements calculate...

Ten established transfemoral amputees completed biomechanical tests after they had been fitted with a new prosthetic knee joint (test sessions: few hours and 3 months fitting). The required adaptation phase fitting of prosthesis is frequently discussed. This considered to be when the test result no longer influenced by patients’ learning processes. study contributes understanding effects experienced users require master various motion patterns being functionally joints. Biomechanical...

The OTTO BOCK 3R60 prosthetic knee joint allows controlled flexion of the under weightbearing in early stance phase, more closely simulating this aspect gait than was previously possible. As amputee transfers weight onto prosthesis gradually flexes up to 15 degrees, thereby cushioning impact acceptance. In contrast all previous polycentric knees, stability new design is biomechanically increased by flexion, rendering a locking feature unnecessary. Clinically, perceives as stable and...

Results from multiple instrumented gait analysis trials of seven traumatic transfemoral amputees capable community ambulation are reviewed. All subjects used a novel rotary hydraulic prosthetic knee offering both stance and swing phase control, in combination with various contemporary ankle-foot mechanisms. Unlike previous units, the Otto Bock 3R80 provides stability whenever desired weightbearing load is applied to prosthesis The mechanical principles basic functions joint described. three...

Retrospectively 20 patients with a surgically treated ankle fracture caused by hobby-accidents were examined clinically and radiologically score modified to Phillips after 12 months postoperatively. Further they have taken part in dynamical gait analysis at the same time. A group of healthy adults was used as control comparable age, sex, height weight. Although 19 out achieved good result evaluation none them noticed any pathological gait, has shown significant slowed speed decreased stride...

Objective: In assessing the postoperative status of a patellar tendon autograft reconstructed knee it is beneficial to consult large body knowledge about measurable passive stability and neuromuscular properties. But there are very few verified data influence rupture operation on gait patient. The purpose present study was evaluate rehabilitation group patients with knees by means parameters in first year.

Patients with chest wall deformities have many particular anatomical, physiological, genetic, biomechanical and psychological characteristics. It is generally recognized that surgical correction of funnel pigeon breast may be done for psychosocial reasons alone. Morphological dynamic investigations are to identify the function deformed permit objective assessment cosmetic functional outcomes operation.
