INTRODUCTION The effect of altered gait on body mechanics presents a stress on patient's sacroiliac joints (SIJ). The gait of the patient is this case report is altered because of a transtibial amputation with prosthesis; he also has a foot drop orthotic. CLINICAL FEATURES A 40-year-old man had left sacroiliac pain. The pain began 3 days before visiting the clinic and has been constant since ...

Users of traditional knee-ankle-foot orthoses (KAFOs) walk with either locked or unlocked knee joints depending on the level of stability required. Some users may benefit from new stance-control KAFOs that prevent stance-phase knee flexion but allow swing-phase flexion. We collected data from nine nondisabled adults who walked with KAFOs that incorporated the Horton Stance-Control Orthotic Knee...

[Purpose] The purpose of this study was to examine the effects of a functional foot orthosis on the knee angle in the sagittal plane of college students in their 20s who had flatfoot. [Subjects and Methods] The subjects of this study were 20 college students diagnosed as having flatfoot. The variations of their knee angle (Q-angle) in the sagittal plane during the stance phase were measured usi...

The authors describe the case of a patient with ankylosing spondylitis who was treated with orthotic devices for postural unleveling. The patient described specific pre-existing postural problems, both static and dynamic, that had been present for many years. A unilateral 9-mm gel heel lift was used, followed by custom-molded orthotic devices that incorporated the heel lift. The patient reporte...

[Purpose] This study investigated the effects of proprietary foot orthotics in young adults with flatfoot to determine changes in the ankle joint angle in the coronal plane during the midstance phase. [Subjects and Methods] The subjects were 15 college students diagnosed with flatfoot. Changes in the ankle joint angle in the coronal plane in the midstance phase were measured using the Vicon Mot...

Background and Aim: Previous gait analysis of partial foot amputee subjects has focussed on quantification of joint angles, moments and powers without quantifying muscle forces. This research aimed to develop a subject-specific musculoskeletal model of a partial foot amputee gait to quantify muscle forces of a lower limb affected by a mid-foot amputation during walking non-invasively. Technique...

Excessive foot pronation has been speculated to be a cause of leg and foot problems among runners. Foot orthotic devices are often used to modify this condition. Examination of the records of 180 patients treated for various running injuries showed that 83 individuals (46%) were prescribed orthotic devices and that 65 of these runners (78%) were able to return to their previous running programs...

[Purpose] This study investigated the short-term effects of a combination therapy consisting of repetitive facilitative exercises and orthotic treatment. [Subjects and Methods] The subjects were chronic post-stroke patients (n=27; 24 males and 3 females; 59.3 ± 12.4 years old; duration after onset: 35.7 ± 28.9 months) with limited mobility and motor function. Each subject received combination t...

The walking mechanism of a prosthetic leg user is a tightly coordinated movement of several joints and limb segments. The interaction among the voluntary and mechanical joints and segments requires particular biomechanical insight. This study aims to analyze the inter-relationship between amputees' voluntary and mechanical coupled leg joints variables using cyclograms. From this analysis, the c...

OBJECTIVE To assess whether the application of Functional Electrical Stimulation improves gait kinematics and walking ability in people with multiple sclerosis who experience foot drop. DESIGN Acute open labelled comparative observation trial. PARTICIPANTS Twelve people (3 females, 9 males, EDSS 2-4) with relapsing remitting multiple sclerosis (47.8 years (standard deviation 6.6)) who were ...
