Gait Disorders, Neurologic
ABSTRACT: Gait disorders in the elderly are common and in most cases cannot be treated medically or surgically. Therefore, treatment often relies on ambulatory devices such as canes, crutches, and walkers. Before selecting a device, the patient should be evaluated to define whether one or both upper extremities are required to achieve balance or bear weight. Patients requiring only one upper extremity can use a cane, while patients requiring both upper extremities are best served by forearm crutches or walkers. The patient's need to bear weight through the device will help the physician choose a specific device. When measuring the device, anatomic landmarks and the angle of the elbow must be taken into consideration. Because time often is limited during a routine office visit, a physical therapist often can provide further training for patients learning to use such a device.
ABSTRACT: Gait instability, urinary incontinence, and dementia are the signs and symptoms typically found in patients who have normal pressure hydrocephalus. Estimated to cause no more than 5 percent of cases of dementia, normal pressure hydrocephalus often is treatable, and accurate recognition of the clinical triad coupled with radiographic evidence most commonly identifies likely responders. Magnetic resonance imaging or computed tomography typically demonstrates ventricular dilation with preservation of the surrounding brain tissue. The abnormality in normal pressure hydrocephalus occurs secondary to an abnormality in fluid removal, leading to an increase in ventricular size and encroachment of enlarged ventricles on adjacent brain tissue. The pressure exerted on the cerebral parenchyma by immense fluid-filled cavities deforms white matter tracts, instigating gait abnormalities and incomplete control of the bladder, as well as difficulties in processing incoming stimulation and in producing expeditious responses. Signs and symptoms often occur as sequelae to an imbalance between the expected ongoing production of cerebrospinal fluid and continuous efflux. Ventriculoperitoneal shunting is used to relieve excess ventricular fluid not absorbed by normal physiologic channels. Multiple studies have explored various techniques to identify patients with normal pressure hydrocephalus in an effort to predict likely benefit from shunting. However, the effectiveness of cerebrospinal fluid diversion has never been proven in a randomized controlled trial comparing use of a shunt versus no shunt.
Charcot Foot: The Diagnostic Dilemma - Article
ABSTRACT: Primary care physicians involved in the management of patients with diabetes are likely to encounter the diagnostic and treatment challenges of pedal neuropathic joint disease, also known as Charcot foot. The acute Charcot foot is characterized by erythema, edema and elevated temperature of the foot that can clinically mimic cellulitis or gout. Plain film radiographic findings can be normal in the acute phase of Charcot foot. A diagnosis of Charcot syndrome should be considered in any neuropathic patient, even those with a minor increase of heat and swelling of the foot or ankle, especially after any injury. Early recognition of Charcot syndrome and immobilization (often with a total contact cast), even in the presence of normal radiographs, can minimize potential foot deformity, ulceration and loss of function. Orthopedic or podiatric foot and ankle specialists should be consulted when the disease process does not respond to treatment.
