Objective: The purpose of this study was to investigate the outcomes of adding lumbar sustained natural apophyseal glide (SNAG) to a conventional therapy program for chronic nonspecific low back pain (LBP). Methods: Forty-two participants with chronic nonspecific LBP were randomly divided into 2 groups. The study group (aged 27.1 ± 8.3, 20 men, 3 women) received a conventional physical therapy program consisted of stretching and strengthening exercises plus SNAG (based on the Mulligan concept) on the affected lumbar levels, and the control group (aged 28.9 ± 7.7, 13 men, 6 women) received the same conventional program without SNAG 3 times per week for 1 month. Outcome measures were repositioning error (the primary outcome), pain, and function measured by an isokinetic dynamometer, visual analog scale, and the Oswestry Disability Index. Measurements were recorded before and after the end of the treatment period. Results: The comparison between pretreatment and posttreatment test scores indicated that both study and control groups had significant improvement in all dependent variables (P N .001). However, adding SNAG to the conventional program resulted in higher improvement in terms of repositioning error, pain, and function (P = .02, .002, .008) respectively. Conclusions: This preliminary study indicated improvement in both groups. Adding SNAG to conventional programs in the treatment of chronic nonspecific LBP may result in greater improvement of repositioning error, pain reduction, and improved function.

Objective: To investigate the effect of bilateral flexible second-degree flatfoot on pelvic and spinal mechanics in young females. Methods: A case-control trial was conducted at the Faculty of Physical Therapy, Cairo University, Egypt, on 60 female participants who were assigned into two groups. Group A (the control group) included 31 healthy subjects, and group B (the study group) included 29 subjects with bilateral flexible second-degree of flatfoot deformity. For each subject in both groups, using lateral weight-bearing radiographs, foot assessments were performed bilaterally to measure the talus–first metatarsal angle. Using the formetric-II device, 3D assessments of the pelvis were performed on the frontal and sagittal planes in addition to lumbar and thoracic curvatures on the sagittal plane. Outcome measures were pelvic inclination, pelvic tilt, and lumbar lordotic and thoracic kyphotic angles. Results: There was a significant difference in pelvic inclination and in lumbar and thoracic angles (P=0.012, 0.009, and 0.028, respectively) between both groups. There was no significant difference between both groups in pelvic tilt (P=0.688). Conclusion: Subjects with bilateral flexible second-degree flatfoot demonstrated increased pelvic inclination, lumbar lordotic and thoracic kyphotic angles than normal subjects. Foot assessments should be performed as an essential part of the evaluation of female patients with spine and pelvic problems. Bilateral flexible second-degree flatfoot may act as a predictor for pelvic organs prolapse in their later lives.
BACKGROUND: Low back pain (LBP) is a common musculoskeletal problem, which commonly affects balance. Sustained natural apophyseal glide (SNAG) is a successful treatment approach for LPB. However, its influence on balance problems has not been studied before. OBJECTIVE: To investigate the immediate effect of SNAG on postural stability and pain in individuals with flexion-dominant chronic low back pain (FCLBP). METHODS: Randomized placebo-controlled trial in which 64 participants with FCLBP were randomly allocated into two groups (SNAG and sham). SNAG group (n= 32) received central lumbar SNAG on the symptomatic lumbar level(s). Sham group (n= 32) received sham SNAG. The outcome measures were postural stability indices; overall stability index (OSI), anteroposterior stability index (APSI), and mediolateral stability index (MLSI) in addition to pain intensity. Outcomes were assessed using the Biodex Balance System and visual analog scale respectively. Measures were taken before and immediately after interventions. RESULTS: There were statistical significance and high effect size (ES) in favor of the SNAG group regarding OSI, APSI, and pain (p> 0.01, cohen’s d ES =1.3, 1.4, 1.1 respectively). MLSI showed moderate ES (cohen’s d= 0.7) but did not reach a statistically significant level (p= 0.05). CONCLUSION: Lumbar SNAG produces an immediate improvement in postural stability and pain in subjects with FCLBP.
