Plain English Summary

Background and study aims
Whiplash is a neck injury caused by a sudden movement forward, backward or sideways movement of the head. It often happens after a sudden impact from, for example, a road traffic accident and results in damage to the ligaments and tendons in the neck. Road traffic accidents and their effects on social-health costs are an important problem for our society. Whiplash and whiplash associated disorders (WAD – for example pain, reduced range of neck movement, neurological damage and even fracture) are the number one reason for people visiting the emergency room after being involved in a road traffic accident. Osteopathic high velocity, low amplitude (HVLA) techniques, and mobilization techniques of the cervical spine, either alone or combined with other treatments, are methods used to treat neck problems. Both treatments result in similar short term changes, but there is not enough data to assess their long-term effects, making it difficult to develop the best technique and when and how long the treatments should be applied. The aim of this study is to precisely and objectively contribute to the knowledge available on how good HVLA techniques are at treating whiplash and WAD. HVLA techniques will be compared with other physiotherapy techniques, looking at how long the treatments are needed, the degree of pain relief they offer, how much they improve the function and mobility of the spine and analysing radiological changes in cervical curvature.

Who can participate?
Patients aged 18 to 65 with WAD admitted to the Osteopathic Centre in Terrassa.

What does the study involve?
Participants are randomly allocated into one of two groups. Those in the study group receive HVLA treatment and the control group receive conventional manual osteopathic therapy and therapeutic exercises. The results from the two groups are then compared to assess how well they treat whiplash and WAD.

What are the possible benefits and risks of participating?
Participants are unlikely to directly benefit from the trial, but the results of this study could help future sufferers of whiplash, resulting in better management of their symptoms and avoiding excessive diagnostic, clinical and therapeutic procedures. The risks associated with this study are rare and generally mild, but include some neurodegenerative reactions (sweating, low blood pressure, feeling sick and / or rapid heart rate) during, or immediately after, the therapy.

Where is the study run from?
Health Consortium of Terrassa (Spain)

Scientific title

Research project on the effectiveness of cervical OSTEOpathic manipulation techniques of high velocity and low amplitude in patients with whiplash-associated disorders: a Randomized Controlled single blind Trial



Study hypothesis

Patients who have suffered cervical whiplash, specific osteopathic techniques to adjust the treatment, of high velocity and low amplitude (SAT-HVLA) of the cervical spine, obtain better results than those treated with combined treatments found in cervical therapeutic exercise manuals.

Whiplash Associated Disorders (WAD)


The participants are randomised to two groups:
1. Treatment: The technique of choice, will be the Specific Adjusting Technique (SAT). This is a High Velocity Low Amplitude Technique, whose objective is to reverse the injury caused by the trauma.
Throughout the trial we will make three interventions with SAT (one every two weeks)
In the first intervention, we will manipulate the upper cervical segment (C2/C3)
In the second intervention, we will manipulate the low cervical segment (C5/C6)
In the third intervention, we will manipulate the upper thoracic segment (T1/T2)
2. Control: The participants will receive conventional treatment, consisting in manual therapy techniques and therapeutic exercises, over four weeks.
