Isometric lumbar extensor strength test and strengthening exercise were performed with MedXTM lumbar extensor machine, which was designed to stabilize the pelvis. After 8 weeks of training program, isometric lumbar extensor strength & other pain related variables were checked again in the same way.


Results
The results were as follows: 1) After 8 weeks of lumbar extensor strengthening program, isometric lumbar extensor strength was increased at all the measured points significantly (p<0.01). 2) VAS and ADL were improved from 6.7 to 3.7, and from 6.9 to 9.1 respectively (p<0.05).


Conclusion
