Stability of walking frames.

Biomechanical tools were used to assess stability for 11 patients who, following the surgical amputation of one lower limb, required the assistance of a walking frame to ambulate. The Walker Tipping Index (WTI), as derived from the forces applied to the walking frame, was developed specifically for this study to examine the relationship between stability and walking frame height during ambulation. However, the WTI may be useful as a criterion of stability to assist clinicians in their evaluation of walker use in a variety of patient populations. Walker stability was examined as subjects, wearing their prostheses, completed 30-sec walking trials in each of the normal, high, and low walking frame height conditions. Adjusting the height of the walker to one setting (3 cm) above or below normal appears to redistribute the load of walking between the upper and lower extremities without adversely affecting stability.

Hematometra as a cause of lumbar radiculopathy. A case report.

Low-back pain combined with a positive straight leg raising test (Lasègue's sign) is uncommon in children and adolescents. Reproductive tract (Mullerian) anomalies causing an accumulation of menstrual blood in the vagina, uterus, and fallopian tubes represent an unusual extraspinal cause of low-back pain. The accumulation of blood in these cavities is termed hematocolpos, hematometra, and hematosalpinx. Amenorrhea with cyclic lower abdominal pain and a presenting pelvic mass are the usual presenting features. In the current report, we describe a case of an adolescent with low-back pain, positive straight leg raising test, and signs of L5 radiculopathy that were attributable to hematometra secondary to congenital partial absence of a vagina. This appears to be the first report of this type of presentation.

Walker user risk index. A method for quantifying stability in walker users.

A method for quantifying the stability of a patient using a walking frame is presented. Data collected from a walker-dependent patient recovering from surgical amputation of his right leg were used to demonstrate the derivation and interpretation of a proposed walker user risk index (WURI). WURI curves express risk to the walker user in terms of how much the upper extremities contribute to overall patient support. The WURI analysis of the walker stride presented here quantified the expected clinical impression that this patient was least reliant on the walker immediately after the advance of his prosthetic leg and most reliant when standing on his prosthesis and swinging his nonamputated leg. The analysis also revealed unexpectedly high upper body loads and specific phases in the gait cycle where the patient's balance was at risk.

Type A personality and marital intimacy in amputees.

The specific characteristics of the Type A personality have generated a great deal of recent attention due to the prevalence of these characteristics in persons suffering from coronary heart disease. Type A individuals are more likely to be involved in serious accidents and experience more secondary complications when faced with serious illness. They are also less apt to incorporate appropriate coping strategies to help deal with pain and discomfort, or to enlist the help of others for such purposes. These studies are particularly interesting for those involved in health care, as such personality characteristics may influence health and healing. The present study examines the Type A personality construct and marital intimacy in a sample of 34 lower extremity amputees. The Survey of Work Styles (SWS) was used to measure Type A behaviour patterns, and the Waring Intimacy Questionnaire (WIQ) to assess the marital relationship. When compared to a group of age- and sex-matched controls, lower extremity amputees showed higher prevalence of some Type A behaviour patterns, and, in males, lower levels of marital intimacy. The low return rate of questionnaires in this study limits its generalizability, but results remain consistent with predictions for Type A behaviour patterns.

A comparison of psychosocial functioning and personality in amputee and chronic pain populations.

OBJECTIVE: To compare two populations with disabling conditions, amputation and chronic pain, in terms of psychosocial functioning and personality factors. We hypothesized that the degree of disability of amputees would resemble that of patients with chronic musculoskeletal pain. We also examined the prevalence of personality characteristics stereotypic of chronic pain in the two samples. DESIGN: Survey. SETTING: Outpatients at the pain and amputee clinics of a teaching hospital. PATIENTS: Ninety-four patients (47.7% of the number approached) were selected in consecutive samples taken from records and clinics. MAIN OUTCOME MEASURES: Sickness Impact Profile (SIP) and the Millon Clinical Multiaxial Inventory (MCMI). RESULTS: The two groups did not differ on the SIP total score. Sixteen of 47 amputees reported significant pain, and this group showed higher levels of overall disability than did patients with chronic musculoskeletal pain (n = 47) and significantly greater disability than the 31 amputees reporting low levels of pain. Contrary to common perceptions of chronic pain patients, 25% showed no significant evidence of psychopathology. Only anxiety and dysthymia levels were clinically elevated in more than 50% of chronic pain patients. CONCLUSIONS: Results are discussed in terms of the dual disability of amputees with chronic pain and of the hazards of attributing common characteristics to heterogenous patient groups.
