High-Velocity Low-Amplitude Approach To Spinal Manipulation

The high-velocity, low-amplitude technique, or HVLA thrust for short, is one of the oldest and most commonly used approach to spinal manipulation. In fact, it is now considered as the traditional chiropractic technique. It can be used to alleviate different musculoskeletal and nervous complaints, particularly low back, mid back, and neck pain.

A voluminous amount of chiropractic clinical researches have focused on the evaluation of the efficacy of this type of spinal manipulation. A review of clinical data in 2010 revealed that aside from alleviating back pain and neck pain, spinal manipulation may also be helpful for other conditions such as migraine and cervicogenic headaches, upper and lower extremity joint conditions, and whiplash-associated disorders.

Common HVLA Techniques

The HVLA approach used in spinal manipulation further branches out to different techniques. Below are a few of the common HVLA spinal manipulation techniques.

As the most frequently used technique, the diversified technique is the form of HVLA thrust that is associated with the traditional chiropractic manual adjustments. To perform this method, the chiropractor applies a high-velocity, which means quick, and low-amplitude, which translates to gentle, thrust at the affected parts or the restricted joints. This is done to each affected joint one at a time. The aim of this application of force is to restore the mobility and the normal range of motion in the joint. In order to optimize the adjustment of the spine, the body may be positioned in specific ways by asking the patient to twist and turn during the treatment.

The “Palmer-Gonstead” technique, which is more commonly known as the Gonstead adjustment, is also an HVLA adjustment similar to the diversified technique. However, the difference is in the process of evaluating and locating the problematic joint and determining the specificity of body positioning. In order to further optimize the treatment, specially designed chairs such as the cervical chair, and tables such as the chest-knee table, may be used to position the patient.

As its name suggests, the Thompson Terminal Point technique or the drop technique, involves a specialized treatment table that features sections that drop a short distance during the HVLA thrust. This table was designed with the premise that by dropping the table surface, the movement of the joint is facilitated. During this treatment, the audible pop that is usually heard when performing spinal manipulation may or may not occur. Because of this, the drop technique may be considered a form of spinal mobilization, which is a gentler adjustment approach than spinal manipulation. This drop technique can sometimes be used in addition to diversified HVLA adjustment. In some cases, it can also entirely replace this diversified technique.

Cracking Sounds

As aforementioned, an audible pop is usually associated with HVLA techniques. This cracking sound is called cavitation and it is caused by a release of gas when the joint is pushed. Even if the joint is only pushed a short distance past its passive range of motion of the joint, it is enough to let loose the gas. This occurrence is very similar to what happens when you crack your knuckles.

For some chiropractors and patients, this audible pop is considered an indication of a successful treatment. However, there is no scientific physiological data from studies with large patient populations that back up this belief.
