Effect of segmental control program on hamstring peak torque, pain and disability in patients with non-specific low back pain: A randomized controlled trial.

AIM: To investigate how a segmental control program impacts hamstring peak torque, pain, as well as functional disability in individuals suffering from Non-specific low back pain.

DESIGN

Single masking, pre-post randomized controlled trial.

SETTING

NSLBP patients from the Outpatient Clinic at Faculty of Physical Therapy, Giza, Egypt.

METHODS

60 patients with NSLBP were randomized into three groups utilizing an opaque sealed envelope. Group "A" (closed kinetic chain), Group "B" (open kinetic chain) and Group "C" (control): all groups were receiving the conventional therapy. Treatment was applied 3 times a week for successive four weeks. The patient's pre and post-treatment evaluation was done utilizing an isokinetic dynamometer, visual analogue scale (VAS) in addition to Oswestry Disability Index for hamstring peak torque, pain intensity and functional disability.

RESULTS

Multiple pairwise comparisons showed statistically significant differences among pre and post-treatment in all variables in the 3 groups, closed kinetic, open kinetic and control group as p-value <0.05. Between groups analysis revealed that there were no statistical significant differences among closed and open segmental control groups while post treatment, a statistical significant differences (p-value<0.05) was observed among closed kinetic and control as well as between open kinetic and control group.

CONCLUSION

In patients suffering from non-specific low back pain, both open as well as closed kinetic chain exercises had a beneficial effect on pain and functional disability.
