Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
1- standard physiotherapy (including infrared heating of the low back for 15 minutes, stretching exercises for back, hamstrings, iliopsoas muscles - 3 repetitions X 30 seconds hold X 30 seconds rest , strengthening exercises for abdominal muscles 1 set X 10 repetitions X 5 seconds hold.
- frequency of standard treatment sessions: 3 x 40 minutes per week for 4 weeks.
- (estimated total session duration is: 40 mins,
2- "SNAG" Mulligan technique applied from setting position on the L4, and L5 spinous processes in a cephalic direction for 3 sets X 5 repetitions (for about 10 mins / session . 3 session /week for 4 weeks). SNAG technique will be applied by physiotherapist.
- SNAG will be applied at the end of the session for the study group only (the total study group session time will be 50 mins. (the 10 minutes lack in control group session time will be filled with examination and history talking to achieve equality in time involved in patients treatment and caring)
Note: first program will be introduced to the control group, the first and second program will be both introduced to the experimental (study) group

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
the included subjects will be selected systematically from a list of the patients attending the faculty of physical therapy out-patient clinic, Cairo, Egypt.
after applying the initial assessment and signing the informed consent, each subject will be asked to pick a closed envelop containing a numbered card. this number will determines if the subject will be in the control or the study groups
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Masking / blinding

Efficacy
Statistical methods / analysis
the number of the sample will be based on the results of a pilot study of five patients before starting the actual study. this is because there are no previous study on the effects of the SNAG on lumbar proprioception
power: 80%
significance level: .95%

Summary
Brief summary
this study has the aim of revealing the effect of Mulligan "SNAG" technique on low back priprioception, pain level, ROM, and functional level in patients suffering from chronic non-specific low back pain.

the primary purpose of this study is to investigate if this technique has an effect on the improvement of lumbar spine proprioception which was proved to be affected in study patient population and may be a cause of their condition.

this study try to investigate a new possible mechanism (effect on proprioception) that can explain the efficacy of SNAG technique reported by previous studies.

this study is considered one of the few available study that tried to think outside the box regarding the effects of snag as one of the mulligan techniques as the majority of the previous studies adopted only the mechanical explanation mentioned by Mulligan himself.
