what exactly is biomechanics and why do you need to understand it?

What is biomechanics?

Biomechanics is interdisciplinary science dealing with the application of mechanical laws to a living organism. It studies the forces that affect the human body and what changes they cause.

The locomotor system is a system for movement, the basis of which is a skeleton consisting of bones and forms the structure of the body that ensures strength and a constant shape. We also have muscles and joints that provide mobility.

Movement takes place around the joints, and muscle activity brings body parts closer and further apart. An example would be the movement of the arm to the body or the movement of the upper leg away from the body.

The impact of Biomechanics in rehabilitation

Quality kinesitherapy (movement therapy) consists of targeted exercises that influence tissue change in the form of improvement of function, i.e. greater strength, greater range of motion and reduction of pain in the safest possible way.

Biomechanics allows us a good understanding of movement which we will use at a certain stage of rehabilitation, and how we can do the progression of the load that is necessary whether it is a sports injury, back pain, neck pain or other orthopedic problem.

Just developing strength and range of motion is not enough. It is also important to understand how one part of the body moves in relation to the other.


Consider the rotation of the scapula when raising the arm above the head.

We are interested in which joints participate in this movement and in what way and why. If we understand the biomechanics of the shoulder, the choice of exercises is very easy and logical.

When we ensure good biomechanics of the said joint, then we can talk about a well-conducted rehabilitation of the same.

Biomechanics in rehabilitation

The biomechanics of walking, running and other movements make it easy for us to choose exercises that we want to achieve the desired change.

As rehabilitation professionals, the goal is to understand what is the simplest way to solve the problem. It is often not necessary to choose more than two to three exercises.


Let's take an example related to sports injuries of muscles or tendons.

It is important to understand how a particular type of muscle contraction affects the muscle itself if we are talking about muscle injuries in the form of muscle strain or rupture and tendinopathy or tendon rupture.

There are times when we don't want a rest , and it is important to understand how and why we will load the tissue with as little risk as possible for the greatest possible positive change.

For which diagnoses do we use Biomechanics?

A good knowledge of biomechanics greatly helps us in the rehabilitation of many diagnoses.

With almost all sports injuries, such as muscle injuries, tendinopathies, joint sprain, joint dislocations, knee injuries, shoulder joint injuries and many othersit is important to understand how in the simplest and safest way we can restore mobility and strength and reduce the risk of re-injury.

In addition to sports injuries, many other painful conditions also require movement with a load, and not rest that is very often wrongly instructed..


Low back pain (if no serious injury is present) is a common example where it is necessary to ensure the mobility and strength of the spine.

It is up to us to make that movement appropriate to the pain and/or level of injury with the best possible economy.

This means that we don't have to do a lot of exercises , but a patient needs to do a targeted movement, for the best and fastest results..
