Orthotic devices and gait in polio patients.

Polio survivors are aging and facing multiple pathologies. With age, walking becomes more difficult, partly due to locomotor deficits but also as a result of weight gain, osteoarticular degeneration, pain, cardiorespiratory problems or even post polio syndrome (PPS). These additional complications increase the risk of falls in this population where the risk of fractures is already quite high. The key joint is the knee. The muscles stabilizing this joint are often weak and patients develop compensatory gait strategies, which could be harmful to the locomotor system at medium or long term. Classically, knee recurvatum is used to lock the knee during weight bearing; however, if it exceeds 10 degrees , the knee becomes unstable and walking is unsafe. Thus, regular medical monitoring is necessary. Orthoses play an important role in the therapeutic care of polio survivors. The aim is usually to secure the knee, preventing excessive recurvatum while respecting the patient's own gait. Orthoses must be light and pressure-free if they are to be tolerated and therefore effective. Other joints present fewer problems and orthoses are rarely indicated just for them. The main issue lies in the prior evaluation of treatments' impact. Some deformities may be helpful for the patients' gait and, therefore, corrections may worsen their gait, especially if a realignment of segments is attempted. It is therefore essential to carefully pre-assess any change brought to the orthoses as well as proper indications for corrective surgery. In addition, it is essential for the patient to be monitored by a specialized team.

Comparison of the repercussions of cLBP in four French-speaking countries.

INTRODUCTION: Sociocultural factors may influence the impact of chronic low back pain (cLBP) on patients. The goal of this study was to compare pain and disability levels, and psychobehavioural parameters in four French-speaking countries in patients with cLBP. METHODS: Two hundred and seventy-eight patients were included: 83 in France, 36 in Morocco, 75 in the Ivory Coast and 84 in Tunisia. Demographic data were collected; pain was assessed using a visual analogue scale (VAS), disability with the Quebec scale, psychobehavioural factors by the hospital anxiety depression scale (HAD), the fear and avoidance beliefs questionnaire (FABQ) and the coping strategy questionnaire (CSQ). A Student t-test was used to compare means. Anova (covariance) was used to test for a "Country Effect", i.e. the incidence of country on outcomes. OUTCOMES: There was no difference in disability levels between countries. A "country effect" was found (p<0.001) for pain (F=2.707), anxiety (F=3.467), depression (F=5.137), fear and avoidance beliefs regarding professional activity (F=1.974) and physical activity (F=5.076), strategy of distraction, dramatization, efforts to ignore pain, prayer, seeking social support and reinterpretation (p<0.01). Pain level was higher in Morocco (p<0.05); anxiety, depression, fear and avoidance beliefs about physical activities were higher in Tunisia (p<0.05) and fear and avoidance beliefs about professional activities were higher in the Ivory Coast (p<0.01). Among the coping strategies used, distraction, dramatization, prayer and search for social support were used more in the Ivory Coast; reinterpretation in Tunisia; seeking social support was less common in France. CONCLUSION: In this population of patients with cLBP, despite similar disability levels across the four French-speaking countries, there were considerable variations in pain level and psychobehavioural repercussions.

Change of impairment, disability and patient satisfaction after total knee arthroplasty in secondary care practice.

OBJECTIVES: To assess the evolution of impairment and disability after total knee arthroplasty (TKA) for osteoarthritis and to seek an association with patient satisfaction with surgery. METHOD: Consecutives patients (n=45, 18 women) with osteoarthritis undergoing primary TKA in two secondary care inpatient clinics were prospectively assessed before one month and six months after surgery. Disability was assessed by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC; range 0-900) and the Lequesne Index (range 1-24). Patients' perceived handicap was assessed on a visual analog scale (VAS, range 1-100). At one month and six months postoperatively, kinetic strength of quadriceps and hamstrings was obtained by isokinetics measures and patient satisfaction on a VAS (range 1-100). RESULTS: Mean age was 71.7+/-7.0 years; mean duration of symptoms was 38.3+/-33.4 months. Patient satisfaction was 83.9+/-17.7 and 83.1+/-22.4 at one month and six months after TKA, respectively. At one month, significant improvements were observed over baseline for pain (-30.73+/-32.2; p<0.01), physical function (Lequesne Index -2.28+/-3.6, p<0.01; and WOMAC score, -82.60+/-148.5, p<0.01), and patient perceived handicap (-21.84+/-29.6, p<0.01). A significant decrease in global knee range of motion was also observed. At six months, significant improvement was observed for pain (-47.96+/-26.8; p<0.01), physical function (Lequesne Index, -5.08+/-3.66, p<0.01; and WOMAC score, -157.04+/-153.2, p<0.01) and patient perceived handicap (-39.60+/-24.1; p<0.01). All isokinetics measures for quadriceps and hamstring were significantly improved between one month and six months after surgery. At one month and six months, the correlation between patient satisfaction and change in impairment, disability and patient perceived handicap was weak. DISCUSSION AND CONCLUSION: Impairment, disability and patient perceived handicap improved significantly after TKA for osteoarthritis. However, these improvements were poorly correlated with patient overall satisfaction with surgery.
