World PT Day 2014 : Physiotherapists play a key role in helping people be 'Fit to take part' in Socio-economic development.
Monday 08 September 2014 - 10:43:49 | International Physiotherapy News
World Physiotherapy Day falls on 8th September every year. It is an opportunity for physiotherapists (known in some countries as physical therapists) all over the world to raise awareness about the crucial role their profession plays in making and keeping people well, mobile and independent. The day was established in 1996, by the World Confederation for Physical Therapy – the profession’s global body representing over 350,000 physical therapists in 106 countries.
Physiotherapists are experts in developing and maintaining people’s ability to move and function throughout their lives. With an advanced understanding of how the body moves and what keeps it from moving well, they promote wellness, mobility and independence. They treat and prevent many problems caused by pain, illness, impairments and disease, sport and work related injuries, ageing and long periods of inactivity.
They work in a variety of settings, including hospitals, health centres, sports facilities, education and research centres, hospices and nursing homes, rural and community settings.
People with disabilities and long-term illnesses have the right to lead full and fulfilled lives as part of society. But many do not, because they have not received the right kind of support. This waste of human potential has a huge cost beyond personal hardship. Several studies indicate that lack of participation by people with disabilities costs some countries 7% of their gross domestic product – reflecting both the loss of so many people not contributing economically and the cost of supporting them.
This is where contributions from physiotherapists matters, they play a key role in enabling persons with disabilities to fully enjoy all human rights and fundamental freedoms letting them contrbute to the socio-economc development – and the message has to go out to politicians and other policy makers that they are worth the investment.
The president of the World Confederation for Physical Therapy (WCPT) Marilyn Moffat is quoted as saying "Rehabilitation is a good investment because it builds human capacity. It should be incorporated into general legislation on health, employment, education, and social services and into specific legislation for people with disabilities."

Study On Manual Therapy Interventions On Vertebral And Internal Carotid Arterial Blood Flow and Cerebral Inflow
Wednesday 11 December 2013 - 09:30:27 | International Physiotherapy News
A recent study that appeared in Physical Therapy Journal conducted by Thomas et al investigated the changes in vertebral and internal carotid blood flow during selective positions that are commonly associated with manual therapy techniques were assumed. This study provides additional evidence toward understanding the role of neck position on blood inflow to the brain.
Twenty participants (10 male, 10 female) with a mean age of 33.1 years were recruited into the study. All participants had normal anatomy of their craniocervical arterial circulation, however three participants (15%) had dominance of one vertebral artery. Inclusion criteria were Healthy subjects, between the ages of 18 and 65 years old, no reported mechanical neck pain or headache. Exclusion criteria were Diagnosed inflammatory joint disease, any history of serious cervical spine trauma (i.e. fractures), any congenital disorder recognized as being associated with hypermobility or instability of the upper cervical spine, diagnosed vertebrobasilar artery insufficiency (VBI), claustrophobia or discomfort in confined spaces (standard contraindication for MRI), and any contraindication identified by the local health authority MRI safety screening questionnaire.
While the MRI was being performed, the patients' cervical spine was positioned in 9 distinctly different positions that simulate positions used in manual therapy techniques. These positions included: neutral position, left rotation, right rotation, left rotation with distraction, right rotation with distraction, left rotation localized to C1–C2, right rotation localized to C1–C2, distraction, and post-test neutral. Blood flow in craniocervical arteries was measured with MRI using a phase-contrast flow quantification sequence. The arterial plane of section was selected to intersect the top of the atlas loop of the vertebral arteries at the level of the C1 vertebra, with imaging extending to just below the atlas loop.
Average blood flow volume measured in milliliters per second was used as the primary test variable and was analyzed in neutral and each of the neck positions for each artery. The average blood flow volume in each artery then was compared between the neutral position and each of the experimental neck positions. Additionally, total blood supply to the brain was determined from the sum of average flow volume (mL/s) in both vertebral and both internal carotid arteries. A meaningful difference between the neutral position and any of the experimental conditions was determined to be > 10%.
Average inflow to the brain in neutral was 6.98 mL/s and was not significantly changed by any of the test positions. According to the data collected, the lowest total blood inflow level was recorded during left rotation (6.52 mL/a). There was no significant difference in flow in any of the 4 arteries in any position from neutral, despite large individual variations. Although mean values of average flow volume were not significant for any position, there were certain individuals with marked flow changes in some positions. Flow generally decreased slightly for both the end-range rotation and distraction positions but increased in the other positions in comparison to neutral. Flow changes were all less than 10%, which is considered to be the normal variation for cerebral inflow.
Secondary to restraints of the MRI and positioning of patients, full end-range rotation may not have been achieved. Additionally, some of the hand positions had to be altered from typical manual therapy techniques due to the constraints of the MRI set-up. None of the tested positions also included the thrust manipulation commonly used concurrently during a manual therapy procedure. Most notably, the results of this study should be cautioned as no subjects were included that presented with neck pain and/or headache symptoms.
Cervical manipulation is a polarizing topic amongst physical therapists and healthcare professionals as a whole. Many believe the risks are not worth the clinical benefits it provides to individuals suffering from mechanical neck pain. This study investigated blood flow to the brain during positions commonly associated with manipulative techniques and found only marginal changes in blood flow with multiple positions. What this study is not able to do (and wasn’t designed to do) is confirm the utility of positional tests for identifying those with blood flow restrictions or confirm that cervical thrust procedures do not involve blood flow changes (the subjects were healthy and there was no thrust used in this study).
This sophisticated study adds nicely to the literature but clinicians still face the conundrum of identifying who may and my not be at risk during a thrust manipulation. Prior to intervening with cervical manipulative techniques, clinicians are urged to follow a thorough evaluation framework similar to that proposed by Flynn et al and the International Federation of Orthopaedic Manipulative Physical Therapists. Cervical manipulation should be implemented with caution and following a thorough subjective and physical examination when indicated by individual patient presentation.
