A record number of retractions are occurring in research due to falsified or fake research.
One lie that many Americans have heard over the years is that resveratrol in red wine is heart healthy. Dipak Das, PhD, a researcher from University of Connecticut Health Center, studied and published articles suggesting that 2 glasses of red wine a night is needed to maintain heart health. In 2012, the University of Connecticut announced that a review board found Dr. Das was guilty of 145 counts of fabrication or falsification of data and at least twenty of his research papers have been retracted.

A parallel study performed at Harvard University found that one would actually need to consume 2000 glasses of red wine a day to ingest enough resveratrol to have a health benefit. Furthermore, scientists at the Johns Hopkins University School of Medicine studied 800 men and women ages 65 and older whose diets were natural high in resveratrol and the study found there was no link between resveratrol levels and the rates of heart disease, cancer, and death (JAMA Internal Medicine).

Another fake and fraudulent article published in 1998 in the Lancet Journal showed an association between Autism and vaccination. This article was eventually retracted, however, currently in some states approximately 4% of children are not vaccinated due to fear of autism.

Vioxx, an anti-inflammatory medication thought to replace the need of people suffering from osteoarthritis from taking large doses of Ibuprofen, is another example of research being falsified. Researchers in the study of Vioxx were well aware of the cardiac challenges associated with taking Vioxx. They decided to selectively remove individuals’ cardiac abnormalities from their data and selectively  hired FDA employees as consultants to prevent negative information from being released to the public.

Duke University’s pharmacokinetics and cancer researcher Anil Potti, MD published that he had found a connection between a person’s genes and a pharmacokinetics cocktail. He built research around his reported findings and received 4 grants (2 of them Federal grants) for his research. However, parallel research conducted at MD Anderson Cancer Center showed that Dr. Potti’s work was all falsified. In 2015 Dr. Potti was found guilty, by U.S. Health and Human Services Department investigators, of engaging in misconduct while researching treatments in human cancer patients. Ultimately Duke University reached a settlement agreement with the federal health agency, patients, and the estates of patients who participated in those medical trials. Dr. Potti was allowed to continue research work, under supervision, until 2020, and Duke University currently has to go through additional steps since being caught for falsifying research on this occasion, and with other researchers.

These research retractions, from falsified and fraudulent studies, are never fully reported to the public or the medical community, and the long-term impact on society is significant.
Most published research findings have little pertinence whatsoever to clinical practice. With over 3 million biomedical publications occurring every year we are now in a race to identify who has a grasp of the best research and who doesn’t.

At Physical Therapy First we work hard as a practice to keep pace with the greatest and latest research, including retracted falsified studies, in order to glide our patients to optimal health and physical therapy outcomes. We also work hard to disseminate the best available medical information to our patients, residents, fellows and students.

Optimal Sleep Position

• What position is best for sleep?
• What kind of pillow should I be using?
• I wake up with neck/back/hip pain or headaches.

These are questions and concerns that a physical therapist will discuss with nearly every type of patient. Although most common in spinal patients, sleep can be an issue with shoulder, hip, headache, and post-operative patients due to difficulty finding a position of comfort. When recovering from an injury, sleep is a crucial time of restoration and healing of injured tissues. If a patient is tossing and turning all night or waking up with pain, then they may be placing excessive strain on the affected body region during their sleep.

SLEEP POSITION: SIDE-SLEEPERS

Most of the following information is related to optimal positioning in the side-lying position, as the majority of people are side sleepers (for at least a portion of the night).

Starting at the neck, it is crucial for side sleepers to have a pillow that is high enough to span the distance between the shoulder and head. This will maintain a neutral cervical spine curve and prevent excessive forward shoulder positioning. Often, for those with broad shoulders, 2 pillows will be necessary or you may use the higher side of a contour pillow (as shown above). The chin should be slightly tucked down to prevent strain at the base of the head.

In the trunk, consider adding a small towel roll or bolster pillow to prop up your waist. The bolster will fit just below the ribs and above the hip bone, creating a neutral lumbar curve. This is especially helpful if you wake with mid or low back pain or have pain when turning in bed.

The above photo also shows a pillow between the knees, which keeps the pelvis from rotating.

Consider this option if you have lateral hip pain that limits how long you can sleep on your side.

BACK AND STOMACH SLEEPERS

Back sleepers make up the next most common position. A very small pillow under the knees can be helpful in those with acute back pain. However, this is not recommended as a long term solution as it can lead to hamstring muscle tightness.

Stomach sleepers make up the smallest percentage, and it is a position to avoid especially in lumbar and cervical spine patients diagnosed with stenosis or spondylolisthesis. A pillow under the trunk from hips to ribs is necessary to achieve a neutral spine. To avoid extreme neck rotation when on your stomach, consider placing your temple region on the end of the pillow and having your face angled towards the bed.

If you struggle with pain while trying to sleep or pain upon waking, discuss your concerns with your physical therapist. At Physical Therapy First, our thorough examination and evaluation allow the therapist to develop a customized treatment plan to improve your quality of life – including when you’re asleep.

Dizziness and Exercise Based Vestibular Rehab
By Sean Phillips PT, DPT, OCS

Millions of people suffer from dizziness every year, making even the simplest daily tasks difficult to perform. However, the word “dizzy” can accompany many different symptoms that someone can suffer from. Dizziness is a non-specific term used for the sense of imbalance, disorientation, vertigo, or light headedness. As we grow older our risk for encountering dizziness increases, and affects women at a higher rate than men. This is especially true when taking 3 or more forms of daily medication, as it is one of the most common side effects of combining medicine.

Feeling dizzy can lead to an increased risk of falls, heightened anxiety and fear levels, depression, and decreased activity levels. Due to this significant impact on daily activities, it is not surprising to learn that dizziness is one of the leading symptoms that would lead someone to seek care. But what can be done to help treat dizziness, especially if it has been going on for long periods of time?

Vestibular rehab has been attempting to treat patients with these complaints dating back to 1946, and today physical therapy is a leading provider for these services. These techniques have concentrated on identifying the causes of dizziness and correcting or reducing the impairments through specific exercises. In this article, we will briefly discuss several categories of dizziness and types of vestibular rehab that can treat specific disorders.

Categories of Dizziness

Vertigo
• True vertigo is a sense of rotation movement. This can feel like the room is spinning around you, or you are spinning around the room. It would be very similar to the sensation you get from someone suddenly stopping you from spinning in a chair, or a getting off a spinning theme park ride.
• Generally provoked by head movements, such as rolling over in bed or quickly looking upwards.
• BPPV = Benign Paroxysmal Positional Vertigo
• Tends to last less than 1 minute.

Disequilibrium
• Sense of poor balance or unsteadiness.
• Worse balance in dark rooms or when closing eyes, such as when washing your face in the shower.

Pre-syncope
• The sensation that someone is about to faint or pass out.
• Typically accompanied by nausea or sweating

Psycho-physiological
• Sensation like rocking on a boat, floating, or rocking

Vestibular Rehab

– VR exercises include eye, head, and body movements that stimulate the vestibular system with a goal of gradually returning a patient to their normal state.
– These exercises include habituation, adaptive strategies, or substitution techniques.
– Habituation exercises uses repetitive movements or provoking stimuli until patients no longer respond adversely to the stimuli.
• For example, if turning head increases dizziness, performing this motion in a controlled environment can gradually resolve the issue.
– Adaptation exercises focus on head movements while keeping eyes focused on a stationary target.
– Substitution exercises utilize the remaining sensory inputs your body has to aid postural control and decrease dizziness.

Conclusion:

In a systematic review of over 300 PT research articles, Kundakci et al. was able to conclude that vestibular rehab was beneficial in treating patients with chronic dizziness. These benefits included improvement in vertigo symptoms, fall risk, balance, confidence, and emotional status. However, they determined that it was not possible to identify the most effective vestibular rehab protocol, frequency, or intensity of exercises, attributing these changes to the high variability between patients.

Therefore, if you may be suffering from chronic dizziness then physical therapy and vestibular rehab may be of benefit to you. Since every patient’s symptoms may be slightly different, your physical therapist should be able to create a unique rehab program to return you to where you would like to be.
