Background of the study: One of the factors leading to non-specific low back pain among University students and staff is prolonged sitting. Exercise therapy is one of the mainstays in the management of non-specific low back pain. One of the most common exercise therapy for non-specific low back pain is the McKenzie method, whereas the Proprioceptive Neuromuscular Facilitation (PNF) exercise is seldom been used to treat non-specific low back pain cases. The purpose of the study was to find the effectiveness PNF and McKenzie method on non-specific low back pain among University population.
Methods: A randomized clinical trial involving 36 subjects (students and staffs) from the University population. The subjects were randomly chosen and assigned to three treatment groups: PNF group, McKenzie group and control group (hot pack and educational home exercise sheet) which underwent 12 treatment sessions distributed over three times in a week for four weeks duration. Subjects were measured on pain score using visual analogue scale. Measurement was performed at three points: pre- test, mid-test and post-test. Repeated measures ANOVA were used to analyse the difference within each group and ANOVA used between the groups in order to find and compare the effectiveness of three treatments.
Result: This study showed that there was significant mean difference between PNF and McKenzie method on pain score (p <0.05) after 4 weeks. Conclusion: The study findings showed that PNF exercise has more effect than McKenzie method on reduction of pain among non-specific low back pain among University population.
