The goals of physical therapy are to decrease back pain, increase function, and teach the patient a maintenance program to prevent future back problems. 
Common forms of physical therapy include: 
1.Passive physical therapy (modalities), which includes things done to the patient, such as heat application, ice packs and electrical stimulation. For example, a heating pad may be applied to warm up the muscles prior to doing exercising and stretching, and an ice pack may be used afterwards to sooth the muscles and soft tissues. 
2.Active physical therapy, which focuses on specific exercises and stretching. For most low back pain treatments, active exercise is the focus of the physical therapy program. 
Exercise Benefits for Low Back Pain: 
Lumbar spine (low back) stability is largely dependent on the supporting abdominal (stomach) and low back musculature. The abdominal muscles provide the initial stabilizing support through their ability to generate pressure within the abdomen which is exerted posteriorly on the spine, thus providing an anterior support column (from the front of the spine). The low back muscles stabilize the spine from the back and lead to posterior support. The bony spine and discs are surrounded by muscles, and the stronger these specific muscles are, the less stress is placed on the discs and joints of the spine. The patients should develop a 'belt' of muscle around their spine. 
Key Aspects: 
In this section, we have briefly listed the key aspects of the role of physiotherapy in management of lower back pain. 
1.Advice and early activity – There is significant evidence to prove that encouraging early movement in case of lower back pain is one of the most significant aspects of treatment in this condition. 
2. Mobilization or Manipulative physiotherapy – This aspect concentrates on promoting mobilization of the specific affected area. The approach of manipulative physiotherapy is used to target the specific point of pain for the purpose. 
3. Specific stabilization exercises – In this aspect of physiotherapy, stress is laid on improving the strength and stability of the muscles which have been weakened due to the lower back pain. 
4. General exercises and stretches – A series of properly structured exercises and stretches are usually carried out in context of the patient’s individual condition and cause of the lower back pain. 
5. Ergonomic advice – Since work-related hazards account for more than 65% of lower back problems, physiotherapists also concentrate on providing accurate ergonomic device, guiding the patient on using the appropriate infrastructure at work to avoid and cure lower back pain. 
6. Postural guidelines – This aspect of physiotherapy focuses on guiding the patient about the correct postural habits and ways to maintain accurate posture to avoid lower back pain.
