Design: Two week test-retest design. Setting: South Western Ontario Amputee Program, London, Ontario, Canada. Subjects: Consecutive sample of 84 individuals, primarily men (78.6%), mean age 56.5 years with a unilateral transtibial (71.4%) or transfemoral amputation related to traumatic (59.5%) or vascular causes. Interventions: All subjects completed a questionnaire containing the FAI and other scales, the 2-minute walk and timed up and go tests during a regularly scheduled clinic visit. Fifty-five subjects completed a second FAI which was mailed to them two weeks later. Twenty-nine others completed the second FAI upon return for testing related to another project. Main measures: FAI, Activity-specific Balance Confidence Scale, Prosthetic Evaluation Questionnaire-Mobility Scale, 2-minute walk, timed up and go and walking device aid use. Results: Relative reliability for the FAI (intraclass correlation coefficient (ICC) = 0.79) and FAI-18 (ICC = 0.78) was acceptable, however bias between measurements was detected. Hypothesized relationships (p B=0.001) between both FAI versions and the Activity-specific Balance Confidence Scale, Prosthetic Evaluation Questionnaire-Mobility Scale, 2-minute walk and timed up and go test were observed. Significant group differences were observed for amputation cause, mobility device use, age and years as an amputee. Neither version distinguished between amputee level or gender groups. Conclusions: The original and modified FAI are valid and reliable tools for unilateral amputees. Reliability is adequate to detect group but not individual level differences. Additional FAI-18 items did not substantially improve the ability to detect between-amputation-group differences.

Retest design. A university-affiliated outpatient amputee clinic in Ontario. Two samples of individuals who have unilateral transtibial and transfemoral amputation. Sample 1 (n=54) was a consecutive and sample 2 (n=329) a convenience sample of all members of the clinic population. Not applicable. Repeated application of the ABC Scale, a 16-item questionnaire that assesses confidence in performing various mobility-related tasks. Correlation to test hypothesized relationships between the ABC Scale and the 2-minute walk (2MWT) and the timed up-and-go (TUG) tests; and assessment of the ability of the ABC Scale to discriminate among groups based on amputation cause, amputation level, mobility device use, automatic stepping ability, wearing time, stair climbing ability, and walking distance. Test-retest reliability (intraclass correlation coefficient) of the ABC Scale was .91 (95% confidence interval [CI], .84-.95) with individual item test-retest coefficients ranging from .53 to .87. Internal consistency, measured by Cronbach alpha, was .95. Hypothesized associations with the 2MWT and TUG test were observed with correlations of .72 (95% CI, .56-.84) and -.70 (95% CI, -.82 to -.53), respectively. The ABC Scale discriminated between all groups except those based on amputation level. Balance confidence, as measured by the ABC Scale, is a construct that provides unique information potentially useful to clinicians who provide amputee rehabilitation. The ABC Scale is reliable, with strong support for validity. Study of the scale's responsiveness is recommended.

A total of 101 patients were studied with a mean age of 69 +/- 14 years, 26 of whom were over age 80. Operative indications were gangrene or ulceration in 80% with rest pain in 20%. Eighteen patients were bilateral amputees. Fifty per cent of the patient population had previous vascular operations. The operative mortality was 13% and was not affected by the age of the patients or the presence of diabetes. Most operative deaths were due to cardiac or septic respiratory complications. Twenty-four of 88 surviving patients were not considered candidates for rehabilitation and the major determining factor was the occurrence of a remote or perioperative stroke. None of these 24 patients was discharged from institutional care. Sixty-four patients were considered rehabilitation candidates with equal distribution in all age groups. Ninety-five per cent of these patients...

Existing tests have limitations such as ceiling effects or insufficient challenge. The objective of this study was to assess the reliability and validity of data for a clinical measure of basic mobility, the L Test of Functional Mobility (L Test). For this methodological study, 93 people with unilateral amputations (74% transtibial, 26% transfemoral; 78% male, 22% female; mean age=55.9 years) were consecutively recruited from an outpatient clinic. Twenty-seven subjects returned for retesting. To assess concurrent validity, subjects completed the L Test, Timed "Up & Go" Test (TUG), 10-Meter Walk Test, and 2-Minute Walk Test, followed by the Activities-specific Balance Confidence scale, Frenchay Activities Index (FAI), and mobility subscale of the Prosthetic Evaluation Questionnaire (PEQ-MS). Amputation cause and level, walking aid use...

The purpose of this study was to evaluate the relative and absolute test-retest reliability of two 6MWT configurations and to evaluate the agreement between these two configurations in users of lower extremity prosthetics. A cross-sectional design was used to analyze data from 25 subjects completing in-patient prosthetic rehabilitation (mean age 63.12 [SD 13.77] y; 72% male). Two configurations of the 6MWT were examined, and relative and absolute test-retest reliabilities were calculated. Bland-Altman plots were constructed to evaluate agreement between configurations. The relative test-retest reliability was excellent for both Configuration 1 and Configuration 2: ICC 0.97, 95% CI: 0.93, 0.98, and ICC 0.97, 95% CI: 0.94, 0.99, respectively. Comparable values for absolute test-retest reliability were also found. The Bland-Altman plot demonstrated a difference of ±63.92 meters between configurations. The two 6MWT configurations had excellent relative and absolute test-retest reliability, but the results from each configuration do not agree sufficiently to make them interchangeable or directly comparable. This highlights the importance of explicitly indicating the test configuration for the 6MWT when reporting results.

Electronic questionnaires are a potential solution; however, the benefits are dependent on the feasibility and acceptance of this mode of data collection among patients. Objective: To determine the feasibility and patient preference/comfort in using a tablet-based questionnaire for data collection in an outpatient amputee rehabilitation clinic compared to a traditional paper-based questionnaire. Study design: Observational study. Methods: In all, 48 patients with major extremity amputations completed both tablet and paper questionnaires related to their amputation and prosthetic use. Both trials were timed; patients then completed a semi-structured questionnaire about their experience. Results: In all, 20.5% of patients needed hands-on assistance completing the paper questionnai...

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.

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.

Objectives: To determine if balance confidence levels differ after discharge from prosthetic rehabilitation and to determine if balance confidence at discharge predicts social activity at three months post-discharge while controlling for important covariates such as walking ability. Study Design: Prospective study. Methods: Subjects ( n = 65) experiencing their first unilateral transfemoral or transtibial amputation were recruited and followed-up one and three months post-discharge. Measures of balance confidence (Activities-specific Balance Confidence Scale) and walking ability (L Test) collected at discharge were used to predict social activity (Frenchay Activities Index) at follow-up. Results: Despite a 14-second mean improvement in walking ability the mean balance c...
