Exercise helps reduce pain. Your physical therapist will advise you to do stretching before and after an exercise or other physical activities. You will also be advised of postural modifications that you may need to make; such as sitting up straight and standing tall instead of slouching. These modifications can relieve compression in your lower back and can help reduce your pain.
It is also important to eat healthy meals and exercise regularly since extra body weight can put unnecessary stress on the lower back and core area. A healthy lifestyle is definitely an important factor in helping with the reduction of lower back pain.
Other treatments include different types of exercises, pain management, and joint mobilization. Any trunk/core exercise that activates the extensors (Para spinals) and the flexors (abdominals) are a great start. A neutral spine squat can also help strengthen your back. After doing these types of exercises and working on increasing mobility, people have reported a great reduction in the recurrence rates of back pain.
