A 54-year-old man with poliomyelitis had been using a conventional, passive knee-ankle-foot orthosis (KAFO) with a drop ring lock knee joint for about 40 years. A stance control KAFO (SCKAFO) with an electromagnetically controlled (E-MAG) knee joint system was prescribed. To correct his gait pattern, he also underwent rehabilitation therapy, which included muscle re-education, neuromuscular electrical stimulation, strengthening exercises for the lower extremities, and balance training twice a week for about 4 months...

Poliomyelitis is caused by an enterovirus infection of the anterior horn cells in the spinal cord. Up to 40% of survivors recover full muscle strength, however 60-90% are left with varying degrees of residual paralysis, where the patient suffers from cramping myalgia and lower motor neuron pattern weakness. This study aimed to identify and quantify, in terms of prevalence and severity of the types of joint deformities encountered in polio sufferers. It also aimed to assess the disability caused by such problems...

Knee-ankle-foot orthoses (KAFOs) are used to assist in ambulation. The purpose of this paper is to review existing KAFO designs which can be grouped into passive KAFOs, stance control (SC) KAFOs, and dynamic KAFOs. The conventional passive KAFOs do not provide any active control for knee motions. SCKAFOs lock the knee joint during the stance phase and allow free rotations during the swing phase. Some SCKAFOs switch between the stance and swing phases using body posture, while others use some kind of a control system to perform this switch...

Ortheses are devices that assist in the function of the limbs, contributing with stability and support to the involved joints. KAFOs (knee-ankle-foot orthosis) are mainly indicated for people with muscular or neural diseases that affect the lower limbs. The actual designs of knee hinges for KAFOs compromise the stability and mobility of the limb. In this work, it was tested the feasibility of a design for a knee hinge for KAFO that should be able to modify its mechanical resistance depending on the gait phase...

BACKGROUND: Spinal cord injury (SCI) influences a person's ability to stand and walk. Various orthoses have been developed to solve these standing and walking problems, however, patients still experience high energy consumption during walking and high forces on the upper limbs. A new reciprocal gait orthosis (RGO) was designed to address these problems. The aim of this study was to evaluate the performance of the new orthosis design with paraplegic subjects. METHOD: Three paraplegic subjects with the lesion at level T12 and three able-bodied subjects were included in this study...

PURPOSE: Excessive movements during walking have been observed by gait analysis in children with arthrogryposis (AMC) using orthoses compared to children using only shoes. The aim of this study was to evaluate energy expenditure and functional exercise capacity in children with AMC. METHODS: Twenty-four children with AMC and 25 typically developing (TD) children underwent oxygen measurement and the 6-minute walk test (6MWT). Children were divided into AMC1 using knee-ankle-foot orthoses with locked knee joints (KAFO-LK); AMC2 KAFOs with open knee joints (KAFO-O) or ankle-foot orthoses (AFO); and AMC3 using shoes...

Muscle weakness resulting from the combined effects of acute and late motor neuron pathology is the basic cause of post-polio dysfunction. Through their normal sensation and moter control, post-polio patients minimize their disability by useful substitutions. Orthoses are needed only when these substitutions either are inadequate or result in muscle or joint overuse. The areas most commonly showing late disability are the lower extremities, shoulders and low-back. In the lower extremities, the major muscle groups are the hip extensors and abductors, the knee extensors (quadriceps), ankle plantar flexors and dorsi flexors...

OBJECTIVE: The aim of the study was to compare the effects of lower extremity orthoses on energy expenditure in patients with cerebral palsy (CP). METHODS: We included 48 children with CP using lower extremity orthosis. Energy expenditures determined based on heart rate, yielded an energy expenditure index (EEI) with and without orthosis during walking. RESULTS were compared statistically between orthosis groups (solid polyethylene ankle foot orthosis (PAFO), articulated PAFO, ground reaction foot orthosis (GRAFO), plastic and metallic knee-ankle-foot-orthosis (KAFO), and metallic AFO)...

This paper presents an assessment of a lower limb exoskeleton for providing legged mobility to people with paraplegia. In particular, the paper presents a single-subject case study comparing legged locomotion using the exoskeleton to locomotion using knee-ankle-foot orthoses (KAFOs) on a subject with a T10 motor and sensory complete injury. The assessment utilizes three assessment instruments to characterize legged mobility, which are the timed up-and-go test, the Ten-Meter Walk Test (10 MWT), and the Six-Minute Walk Test (6 MWT), which collectively assess the subject's ability to stand, walk, turn, and sit...

Most patients with spinal cord injury use a wheelchair to transfer from place to place, however they need to stand and walk with orthosis to improve their health status. Although many orthoses have been designed for paraplegic patients, they have experienced various problems while in use. A new type of reciprocal gait orthosis was designed in the Bioengineering Unit of Strathclyde University to solve the problems of the available orthoses. Since there was no research undertaken regarding testing of the new orthosis on paraplegic subjects, this study was aimed to evaluate the new orthosis during standing of paraplegic subjects...

Individuals with quadriceps muscle weakness often have difficulty generating the knee-extension moments required for common mobility tasks. A new device that provides a knee-extension moment was designed to help individuals perform sit-to-stand and stand-to-sit. The knee-extension-assist (KEA) was designed as a modular component to be incorporated into existing knee-ankle-foot-orthoses (KAFO). The KEA loads a set of springs as the knee flexes under bodyweight and returns the stored energy as an extension moment during knee extension...

To compare various novel and conventional systems for locomotion, a 25-year-old man was studied with motor complete spinal cord injury at the T4/5 level. He used various devices in the community, and changes in speed, physiological cost index (PCI), and oxygen consumption were measured periodically. Speed was fastest with a conventional manual wheelchair (nearly 120 m/min in a 4-min test). Speed was about 30% less, but the PCI was lowest (highest efficiency) using functional electrical stimulation (FES) of the quadriceps and hamstring muscles to propel a novel wheelchair...

BACKGROUND: Objective design criteria for orthotic components is lacking. This paucity of data results in prescription guidelines based on assumptions or practitioners' past experience, and the potential for incorrectly designed components. The purpose of this study was to directly measure loads on the knee joint of a knee-ankle-foot orthosis. STUDY DESIGN: Case series. CASE DESCRIPTION AND METHODS: Three subjects who had been prescribed a knee-ankle-foot orthosis for quadriceps weakness underwent gait analysis and orthotic upright load data collection...

Falls are prevalent reasons for spinal cord injury (SCI). Postinjury fear of falling (FOF) can affect rehabilitation potential. We quantified FOF in 15 men with paraplegia (ambulatory with bilateral knee-ankle-foot orthoses [KAFOs] and elbow crutches) in correlation with their postural control at the center for long-term SCI rehabilitation of a tertiary-care teaching hospital. Our outcome measures comprised the American Spinal Injury Association Impairment Scale, the Modified Falls Efficacy Scale (MFES), postural sway measurements in the anteroposterior and mediolateral directions; and walking speed, cadence, and endurance...
