Rectus femoris transfer is frequently performed to treat stiff-knee gait in subjects with cerebral palsy. In this surgery, the distal tendon is released from the patella and re-attached to one of several sites, such as the sartorius or the iliotibial band. Surgical outcomes vary, and the mechanisms by which the surgery improves knee motion are unclear. The purpose of this study was to clarify t...

BACKGROUND To examine the intra and inter-rater reliability of lumbar flexion and extension measurements attained using three landmarking methods for dual inclinometry. METHODS This was a repeated measures reliability study. Convenience sampling was used to obtain forty volunteer subjects. Two assessors measured a series of lumbar flexion and extension movements using the J-Tech™ dual inclino...

STUDY DESIGN Descriptive, cross-sectional design of healthy young adults. Continuous motion monitoring of the cervical spine performed outside of a laboratory setting. OBJECTIVE The objective of this study was to quantify the daily frequency and magnitude of neck motion in healthy human subjects using continuous motion monitoring. SUMMARY AND BACKGROUND DATA Daily frequency and magnitudes o...

Computer-assisted surgery was developed to improve the results of conventional total knee arthroplasty (TKA). The authors investigated the preoperative varus/valgus deformity influence on the production of balanced extension and flexion gaps using computer-assisted surgery. This study evaluated data from a prospective case series. A total of 132 patients (107 women and 25 men) underwent navigat...

Purpose: To assess the utility of a 2D dynamic HASTE sequence in assessment cervical spine flexion-extension, specifically (1) comparing spondylolisthesis to radiographs and (2) assessing contact upon or deformity cord.Methods: Patients with flexion-extension sagittal addition routine sequences were identified. Static listhesis was first determined on reviewed consensus. Blinded independently p...

OBJECTIVE To determine the effectiveness of the Rapid Form Cervical Vacuum Immobilizer in controlling the cervical spine movements of a football player wearing shoulder pads and a helmet. DESIGN AND SETTING We used a 1-group, repeated-measures experimental design to radiographically assess cervical spine range of motion with and without the Rapid Form Cervical Vacuum Immobilizer. Two experime...
