What Exercises for My Core Can Help Prevent Lower Back Pain? by charlestlee

First – generally there are different roles of muscles in your trunk. Typically the smaller ones closest to your spine are considered ‘local’ muscles. Such muscles as the transversus abdominis, diaphragm, pelvic floor, and lumbar multifidus provide segmental control of your lumbar vertebra. Real-time ultrasound imaging can be used to visualize the proper contraction of these muscles as we cannot see these muscles from the superficial skin. So first step in core stability is to ensure that the smaller muscles are engaging properly. Then you have ‘global’ muscles which are the larger muscles – such as rectus abdominis, obliques, paraspinal muscles. These muscles are designed for power and stability at higher loads. Core stability exercises should integrate the function of the ‘local’ and ‘global’ muscles in proper sequence.

Once that is established, any asymmetries of the muscles should be determined. In back pain patients, it is very common to have one side of the oblique muscles contracting properly while the other side does not. This causes an imbalance of forces on your trunk and can cause increased torque to your spine – eventually leading to back pain due to excessive torsional stresses in your daily function or sport.

Once the asymmetry is addressed, integration of muscles from above and below the core need to be assessed.  The old saying ‘the knee bone is connected to the hip bone’ goes too with the muscles in your body. Such lower leg muscles as the gluteal muscles in your hip or the latissimus dorsi in the mid back affect the way your core muscles in daily function and sport. People with back pain, typically have an improper tone and sequence of these muscles working together. Over time this places increased stress on the back – regardless of how strong your core is.

As you can tell, there is a lot to consider when training your core. To recommend a standard protocol of exercises to help your back is not specific enough. A proper assessment of your muscle control and movement patterns should be assessed by a qualified movement specialist – such as a Physical Therapist – to determine what the appropriate level and progression of exercises for proper stability and prevent back injury.

Can Strengthening your neck muscles prevent headaches? by charlestlee

There are different types of headaches. One common type is called a cerivcogenic headaches or neck-related headaches. There is lot of research coming out of the University of Queensland in Brisbane, Australia that has discovered how proper stabilization of the neck muscles can reduce neck pain, whiplash injuries, and cervicogenic headaches.

Proper stability of the neck muscles comes first from the smaller muscles closest to the spine. This includes a wafer thin muscle on the front of the cervical spine called the longus colli. A skilled Physical Therapist can instruct a patient how to contract this muscle in isolation and train its endurance. As the longus colli function improves it is important to incorporate strength of the larger muscles such as the sternocleidomastoid and posterior neck muscles to provide stability and strength for the neck to function during the day and in sport.

Cervicogenic headaches are typically generated from dysfunction of the upper neck vertebrae such as C1-3 vertebra levels. With poor postures or previous whiplash injuries the smaller muscles can weaken or inhibit leaving the joints vulnerable to injury due to lack of muscle support.

By improving proper muscle stability, the cervical vertebrae have better support and can last longer in prolonged postures and sporting activities. In turn, the prevalence of headaches can be reduced.
