A 54-year old female, retired due to progressive cognitive decline, was diagnosed with early-onset Alzheimer's dementia. Conventional medication therapy for dementia had proven futile. Initial evaluation revealed a non-verbal female seated in a wheelchair, dependent on 2-person assist for all transfers and activities of daily living (ADLs.) She had been either non-responsive or actively resistive for both ADLs and transfers in the 6 months prior to assessment. Following a total of 17 one hour therapy sessions over 19 weeks in a warm water therapy pool, she achieved ability to tread water for 15 minutes, transfers improved to moderate to-maximum assist from seated, ambulation improved to 1000' with minimum-to-moderate assist of 2 persons...

A 16-year-old girl who had Morquio syndrome presented with severe bilateral hip pain and limited mobility because of bilateral hip osteoarthritis and fixed flexion deformities. She was wheelchair bound for the previous 6 months. Cervical spine flexion-extension views showed mild subluxation (<3 mm), and there was thoracolumbar spine kyphosis. Magnetic resonance imaging of the cervical and thoracolumbar spine showed hypoplasia of the odontoid and vertebral bodies, but no spinal cord compression. Bilateral cemented total hip arthroplasty was performed through a posterior approach under general anesthesia with fiberoptic intubation...

Spinal cord injury (SCI) is a widely disabling condition, constraining those affected by it to wheelchairs and requiring intense daily care and assistance. Cell replacement therapies, targeting regeneration of cells in the injured cord, are currently gaining momentum in the field of SCI research. Previous studies indicate that mesenchymal stem cells (MSCs) can reduce functional deficits through immunomodulation and production of trophic factors in a variety of neurological disorders. The present study assessed the efficacy of transplanted bone marrow-derived MSCs at different concentrations and locations for promoting functional recovery following SCI...

Caudal Regression Syndrome (CRS) is a rare disorder which consists of abnormalities in the lumbosacral spine, rectum, urinary system and lower limbs. These abnormalities also include orthopaedic deformities, such as hip dislocation, knee-flexion contracture with popliteal webbing and talipes equinovarus. Because of the rarity of this condition, few medical personnel are aware of it. Here, we present a case of CRS in a 15-year-old girl with pressure ulcers on the lateral malleolus and plantar surface of the foot, which had come into contact with the wheelchair footrest...

CASE DESCRIPTION: We report a reconstructive case in a paraplegic patient, who suffers from a severe proximal femur infection. Aiming at the preservation of the capacity to remain in a seated position to operate a wheelchair, lower leg rotationplasty was considered suitable for reconstruction. Due to severe infection and subclinical femoral artery stenosis, rotationplasty was supercharged by the inferior epigastric artery. Furthermore, extensor tendons of the foot were attached to the acetabulum to facilitate stability of the neo-hip joint...

The efficiency and the rolling resistance in wheelchair propulsion play an important role in the comfort and the health of wheelchair users in daily life. Here we identify these fundamental interactions of wheelchair-user system on treadmill and on track. We measured the oxygen uptake (input) and the propelling torque (output) as the parameters with velocity and tire pressure. The efficiency increased about 9-13% as the velocity increased on treadmill and it increased around 11-12% as the tire pressure reduced on track...
