Postural and eye-blink reactions to acoustic startle probes were examined in 24 volunteers, who completed two blocked conditions (baseline, startle). A postural reaction during the startle condition demonstrated a reflexive movement in the anterior-posterior direction, which was not observed during the baseline condition. This reflexive response was positively associated with the eye-blink refl...

The purpose of this study was to examine the effects of 7 weeks of isokinetic training on knee extension and flexion peak torque, torque acceleration energy, average power, and total work, and to observe the relationship between the increases in each of the isokinetic measures. Seventeen intercollegiate lacrosse players served as subjects and were assigned to an exercise or control group. Isoki...

Knee postburn scar flexion contractures, making up 22% of large joint contractures [1], affect the leg motion, impair the lower extremity function, present cosmetic defects, and requiring surgical treatment. The contracted scars undergo (during joint extension) severe tension, tearing, and often are converted to pathologic scars-rough, thick, solid, prone to keloid growth and ulceration. Review...

Degenerative arthritis of the elbow is a poorly recognised condition, usually seen in a middle-aged man with an occupation or activity which involves the repetitive use of his dominant arm. Flexion contracture and pain at terminal extension are common presenting features. Fifteen patients were reviewed at a mean of 33 months after debridement by ulnohumeral arthroplasty. Fourteen had good relie...

PURPOSE This study compared the analgesic effects of local infiltration analgesia (LIA) and femoral nerve block (FNB) after total knee arthroplasty (TKA) and assessed factors associated with analgesia obtained by these two methods. MATERIALS AND METHODS Study subjects included 66 patients (72 knees) who underwent TKA for osteoarthritis of the knee. Pain visual analogue scale (VAS), the amount...

BACKGROUND A post-burn flexion contracture of the knee joint is a disabling condition which interferes with an upright posture and a bipedal locomotion. Islanded perforator flaps have been used to resurface the tissue defect which is produced as a result of the contracture release. Despite their various advantages, they are limited by an increased tendency to undergo venous congestion. Perforat...

Children with axillary burns often develop scar contractures that restrict shoulder movement. Objective data on functional movement patterns after contracture formation is sparse. The purpose of this study was to determine how axillary contractures affect shoulder movement during activities of daily living (ADLs). This was a prospective study of children with axillary contractures scheduled for...

Fixed knee flexion deformity can present as an insidious and significant problem in diverse etiologies, most commonly in cerebral palsy. Traditional surgical intervention has included posterior capsulotomy and supracondylar femoral osteotomy, both of which carry significant associated morbidity and risks. In the skeletally immature patient, guided growth may be used to correct or substantially ...

Kinematic data on primate head and neck posture were collected by filming 29 primate species during locomotion. These were used to test whether head and neck posture are significant influences on basicranial flexion and whether the Frankfurt plane can legitimately be employed in paleoanthropological studies. Three kinematic measurements were recorded as angles relative to the gravity vector, th...

BACKGROUND: Performing total hip arthroplasty (THA) or replacement (THR) in ankylosis is not a simple procedure. CASE PRESENTATION: We presented complicated case of patient with flexion contracture and joint due to neglected avascular necrosis femoral head treated THR on one thigh, periprosthetic fracture the other which was also later. One year after surgery, both hips function improved able w...
