Foot and ankle sensory neuropathy may result from a variety of pathologic conditions, especially diabetes mellitus. Decreased sensation, particularly on the plantar surface of the feet, leads to obvious risks of cutaneous injury. Less obvious are the risks of fall-related injury associated with changes in other sensory systems of the foot and ankle, such as the receptors involved in joint movement and position perception. The results of a number of studies demonstrate that the neuropathic process affects these receptors in individuals with diabetes mellitus. Associated with the decreased sensory function of the foot and ankle is decreased performance on tests of static and dynamic postural stability. Subjective feelings of instability and an increased incidence of fall-related injuries have also been reported. The reduced postural stability in persons with diabetic neuropathy cannot be attributed exclusively to loss of plantar cutaneous sensation; it appears to be the result of a general loss of peripheral sensory receptor function in the lower legs, including that of the muscle spindles. During the evaluation of an individual with foot and ankle sensory neuropathy, the possibility of balance deficits should be given proper attention. Assessment of balance deficits could be particularly important when planning the course of rehabilitation for individuals with foot and ankle neuropathy who use modified footwear or have an amputation of a section of the foot or lower extremity.

Study Design: Review of selected literature describing the outcomes related to the management of acute Charcot foot arthropathies in patients with diabetes mellitus. Objective: To familiarize the rehabilitation specialist with the general principles of nonsurgical management for patients with acute neuropathic arthropathies of the foot and ankle. Background: Neuropathic (Charcot) arthropathy of the foot or ankle is the most destructive and disabling chronic complication of all diabetic foot disease. Methods and Measures: We discuss the clinical presentation and the role that orthopaedic and sports physical therapists may have in identifying and preventing complications and the long-term disability associated with these arthropathies. We summarize the outcomes of 15 published reports from 1985-1999 located using the MEDLlNE database from 1966-present. Studies were selected and included if the authors reported on (1) 2 or more patients with diabetes mellitus and acute Charcot arthropathies; (2) the short-term or long-term outcomes, including the length of follow-up; and (3) the pattern or location of the arthropathy. The short-term outcomes (percentage of patients healed, average time to healing) and long-term outcomes (percentage in whom treatment failed, amputation, disability) after treatment by immobilization alone or immobilization after surgery were reviewed and summarized. Results: The prognosis for an individual with severe neuropathic skeletal foot deformities is poor. Eleven deaths (3.65%) in 301 patients were reported within the average follow-up period of 2.5 years after treatment for Charcot arthropathy. Partial or complete foot amputation occurred in 20 (6.6%) of 301, whereas 83 (28%) of 301 patients reviewed had mobility limitations or required ankle-foot orthoses or permanent bracing or assistive devices for ambulation at the time of follow-up. Conclusion: Rehabilitation specialists can improve the short-term outcomes and limit the long-term disabilities in patients with diabetes mellitus and peripheral neuropathy. Early recognition and prompt immobilization are the basic principles of nonsurgical management that influence therapeutic outcome.

Plantar fasciitis is a common pathological condition of the foot and can often be a challenge for clinicians to treat successfully. The purpose of this article is to present and discuss selected literature on the etiology and clinical outcome of treating plantar fasciitis. Surgical and nonsurgical techniques have been used in the treatment of plantar fasciitis. Nonsurgical management for the treatment of the symptoms and discomfort associated with plantar fasciitis can be classified into 3 broad categories: reducing pain and inflammation, reducing tissue stress to a tolerable level, and restoring muscle strength and flexibility of involved tissues. Each of these treatments has demonstrated some level of effectiveness in alleviating the symptoms of plantar fasciitis. Previous studies have grouped all forms of nonsurgical therapy together. It is, therefore, difficult to determine if one type of treatment is more effective compared with another. Until such research is available, the clinician would be wise to include treatments from all 3 categories.
