Functional repercussion of polyarthrosis of the elderly in tunisia.

INTRODUCTION: Osteoarthritis (OA) is the most common degenerative joint disease in the elderly. The often multifocal location at this age can be a source of pain, limitation of everyday activities, thus affecting their quality of life. AIM: To evaluate functional status of aged people with generalized OA in Tunisia, and to detect the main factors associated with a poor function in order to optimize their medical care. METHODS: A cross-sectional, descriptive study done between January and March 2017. Fifty patients were included, aged 65 years and over followed for generalized osteoarthritis. The functional repercussions of polyarthrosis was assessed by functional independence measure (FIM), the Lequesne Algofunctional Index, the Womac index for hip and knee OA, and the Oswestry questionnaire for low back pain. RESULTS: The mean age of patients was 71.94 ± 0.8 years with a sex ratio of 0.42.The functional status of patients with polyarthrosis were altered to varying degrees. The most impaired dimensions of FIM were self-care, transfers and locomotion. Activities of daily living of the Lequesne index was the most impaired section with an average of 5.28. The three dimensions of the Womac index were affected, particularly the pain section with an average of 49.18/100. The Oswestry index was altered with an average of 18.89 / 40. Factors associated with poor functional status were: Female gender (p<0,05), age of development (p<0,05), spinal arthrosis (p<0,05) and history of falls(p<0,05). CONCLUSION: Polyarthrosis is accompanied by functional impairment in the elderly. Factors associated with functional impairment should be considered in the Patient Management Program.

[Validity and reliability of Spinal Mouse to assess lumbar flexion]. / Validité et reproductibilité du Spinal Mouse pour l'étude de la mobilité en flexion du rachis lombaire.

OBJECTIVES: To evaluate the validity and reliability of the Spinal Mouse model to assess lumbar spine flexion. MATERIAL AND METHODS: For the validity study, patients with low-back pain underwent radiography to produce 2 lateral radiographs, first from the neutral position, and then with full trunk flexion. The correlation between mobility as assessed by radiography and the Spinal Mouse were evaluated by use of Spearman's correlation coefficient (SCC) for segmental mobility (L1-L2, L2-L3, L3-L4, L4-L5 and L5-S1) and global mobility (L1-L5 and L1-S1). Reliability was studied in healthy volunteers by the intraclass correlation coefficient (ICC). RESULTS: A total of 20 patients (8 women) aged 41.6+/-8.6 (range 24-63), were included in the validity study. The SCC between radiography and Spinal Mouse measures were 0.55; 0.64; 0.69; 0.54; 0.19; 0.7; and 0.86 for flexion mobility of the L1-L2, L2-L3, L3-L4, L4-L5, L5-S1, L1-L5 and L1-S1, respectively. A total of 45 subjects aged 24.2+/-3.7 (range 20-29) were included for the reliability study. For intrarater reliability, the ICC was 0.84; 0.89; 0.96; 0.97; 0.63; 0.95 and 0.83 for the L1-L2, L2-L3, L3-L4, L4-L5, L5-S1, L5-S1, L1-L5 and L1-S1, respectively. For interrater reliability, the ICC was 0.75; 0.81; 0.79; 0.60; 0.83; 0.85, respectively. CONCLUSION: The Spinal Mouse has acceptable metrological properties to assess segmental and global lumbar mobility during trunk flexion. Its metrological properties are not acceptable to assess mobility of L5-S1.
