I would suggest lots of core stability work, initially working on just transversus abdominis activation which back pain patients often find extremely difficult to maintain the contraction or indeed even get a contraction! I have found that starting in prone then progressing onto supine with knees flexed has been good. Combine this with multifidus strengthening. Then progress onto dynamic trans. abs activity. Once the patient can maintain contraction of trans abs I get them working on core stability with the Swiss/Gym ball, and this is fantastic for low back pain patients progressing their rehab after gaining the ability to use trans abs and multifidus as a 'corset' around the back. Also do lower back extensions on the gym machines but emphasise that it is a controlled small extension with pelvis maintained in neutral with trans abs and multifidus contraction, and of course the same with abdominal machines, I feel the important thing is that as long as they maintain a good neutral alignment with good 'corset' effect of the trans abs and multifidus then they can do alomost anything at the gym.
