Distribution of the three McKenzie syndromes among patients with low back pain in selected outpatient Physiotherapy facilities in Nigeria

Öz

This multi-centre study investigated the distribution pattern of the three McKenzie syndromes among patients with low back pain (LBP) from the out patient physiotherapy departments of some selected medical facilities in Oyo, Ogun and Lagos States of Nigeria in order to establish the distribution index for patients suffering from LBP. Patients were selected using a consecutive sampling technique. Patients were examined and classified using the McKenzie assessment protocol. A total of 66 patients (57.6% males and 42.4% females) suffering from LBP of lumbar spine origin out of the 78 referred to the selected medical facilities qualified for the study. Data were analysed using descriptive statistics and interferential statistic of independent t-test. Alpha level was set at 0.05. Result showed that patients with derangement syndrome constituted 83.0% of the patients’ population while dysfunction syndrome and postural syndrome were 9.0% and 8.0% respectively. It was concluded that derangement syndrome is predominant, in the studied population.

Keywords: Distribution pattern, McKenzie syndromes, low back pain.

Résumé
Cette étude multicentrique investiguait la fréquence de distribution de trois syndromes de Mckenzie parmi les patients ayant les courbatures en clinique de physiothérapie dans certaines centres médicales des provinces d’Oyo, d’Ogun et de Lagos au Nigeria, dans le but d’établir l’indexe de distribution des patients souffrant des courbatures lombaires.Les patients étaient sélectionnés consécutivement, examinés et classifiés en utilisant le protocole d’évaluation de Mckenzie. Au total 66 patients (57.6% males et 432.4% femelles) souffrant des courbatures d’origine lombaire des 78 patients referés, participaient à cette étude. Les données étaient analysées par une statistique descriptive et inferentielle, le test-t avec un degré de confidence de 0.05. Le résultat montrait que les patents avec un syndrome de perturbations constituaient 83.0% de cette population étudiée alors que le syndrome de malfonctionement et le syndrome postural étaient de 9% et 8¨% respectivement. Nous avons conclu que le syndrome de dérangement est prédominant dans la population étudiée.
