Yoga, Sama and the Spine

Spine in sama is when the spine is in line and taking its natural curve. The spine needs to be practice towards the state of sama as the “conditioned” spine is not yet there.
So what is sama and what are the natural curves of the spine?
The meaning of sama is not grasped by one word in English but takes many words to point towards the same meaning. Such as similar, balance, evenness, union, equanimity, wholeness, one, etc. In my opinion, the word sama and yoga point towards the same direction.
There are three natural curves in a healthy spine –
1. the neck (cervical spine) curves gently inward – lordosis.
2. the mid back (thoracic spine) curves slightly outwards – kyphosis
3. the lower back (lumbar spine) also curves inward – lordosis.
These natural curves of the spine are caused by the muscles, ligaments and tendons that are connected to the vertebrate of the spine. These structures support the spine and without the, the spine would collapse. Learning how to maintain a neutral spinal alignment helps to stabilize the spine during daily activities, i.e. sitting, walking, standing and doing yoga asanas.
Due to different reasons, not many people has a healthy spine that has front-to-back curves. To avoid misalignment in our spine when standing for instance, we need ‘align’, followed by ‘stabilise’ and then ‘lift’ the following 3 platforms.
1. Foot and ankle:
– broaden the metatarsals
– press all four sides of the feet down into the ground evenly
– outer ankle to be drawn in and up, while inner ankle lifts up and out
– lift up through the legs to protect the knee and never lock the knee.
2. Pelvic girdle
– press back the femurs
– lift up the frontal hip bones
– broadens the sacrum and keep the side pelvis forward
After getting the alignment in placed, elongate through the torso and side ribs. Stabilise by drawing the side hips and thighs to draw in to the midline. Avoid hypo-extension (rounding lumbar spine) and hyper-extending (over arching the lower back).
3. Shoulder Girdle:
– lift the top of the sternum and broaden across the collar bones
– depress the shoulder blades and move the scapula down the back
– move the upper arm bones slightly back in line with the coronal plane
-draw the trapezius muscles down the back
After getting into the alignment, soften and drop the bottom front ribs and elongate through the thoracic spine and neck. This will help to protect the cervical spine. In cases of hunch in the back, strengthen the upper back postural muscles and pull the shoulders outwards and move the scapula down the back. At the same time, check for wrinkles on joints of humerus to avoid excess shoulders pull.
A crooked or compressed spine will result in poor alignment in the asana and it is highly unlikely that the yogi can find sama in any of the asanas.

Yoga and the spine

Recently a friend of mine had major back surgery, and complained to me that his functionality didn’t seem to be improving. I asked if he had been given any basic exercises to help improve his mobility during his recovery and he said he hadn’t. I felt sure yoga could help him improve his condition and recommended as such, since I have been interested in how Yoga can benefit the spine and our overall functionality.
The spine is an essential part of our bodies overall system contributing to our overall stability and structure, housing our spinal cord (which transmits neural signals between the brain and the rest of the body) and provides us with great flexibility and mobility.
As these systems evolved over millions of years and became crucial to our survival, they required the development of a protective structure that allows for free movement, but is stable enough to offer protection to these delicate tissues.
From an engineering perspective the human structure is the least mechanically stable of all creatures, which is where Yoga can help.
There are generally thought to be four possible movements of the spine, flexion, extension, axial rotation (twisting), and lateral flexion (side bending). These four movements occur spontaneously in everyday life, however there are of course yoga postures that emphasize these movements as well.  There is also a fifth possibility of motion called axial extension, however you have to learn to invoke this particular motion intentionally as it is somewhat unnatural.
Studies have shown that those who practice yoga as little as twice a week for eight weeks make significant gains in strength, flexibility and endurance, which is a basic goal for rehabilitation programs for back or neck pain.
Spinal twisting asanas are an important series for spinal health. The twist imposed on the spine and the whole trunk exercises the muscles, makes the whole spinal column more flexible and stimulates the spinal nerves. They also have a strong influence on abdominal muscles, alternately stretching and compressing them as the body twists from one direction to the other.
Forward bending asanas generally speaking are a passive process in which gravity is utilized to stretch and pull the body forwards. These postures help to loosen up the back, maintaining good health and increasing vitality. These types of postures move the body into a position known as the primary curve (or the fetal position taken in the womb). During a forward bend asana each of the vertebrae is separated, stimulating the nerves, improving circulation around the spine and nourishing the spinal cord. This group of asanas is also very important for making the back muscles supple and strong.
Back bending asanas stretch the abdominal muscles, and tone and strengthen the muscles controlling the spine. The spinal nerves, which emerge from the adjoining vertebrae, are decompressed. This has beneficial repercussions throughout the body since these nerves give energy to all the other nerves, organs and muscles within the body. Research has shown that 90% of backache is a result of muscular imbalance. If these balances are prolonged then the vertebral column in misaligned, the ligaments are strained and the symptoms of back pain begin to manifest.  The practice of a balanced regime of forward, back bending and twisting asanas can correct postural defects and address neuro-muscular imbalances in the vertebral system.
In addition the breathing and meditation aspects of yoga include a ‘relaxation response’ that has been found in many studies to assist people in decreasing their pain. Yoga has also been found to be helpful in the treatment of depression and anxiety that often accompany pain problems.
