Cognition/Memory/Emotion
Obesity/Diabetes/ Cardiovascular disease
Physical activity & recovery
Pain perception & tolerance
Definition and discussion of Obstructive Sleep Apnea (OSA) including;
Definition and discussion of Restless Legs Syndrome (RLS) including:
Practice assessment using validated questionnaires.
Summary & Conclusion
Relevance to Physiotherapy Profession:
Current research has demonstrated a multitude of important impacts of sleep on general health. As Physical Therapists, we are well aware of the negative impact on sleep of the painful conditions that we treat. Do we know enough, however, about other syndromes that disturb sleep? Both Obstructive Sleep Apnea and Restless Legs Syndrome can cause significant sleep disruptions with major impacts that should be taken into account when assessing and treating these patients. These conditions, if present in our patients, can complicate diagnosis and will impact the outcomes of our treatment plans. Increasing our knowledge base in conditions that disrupt sleep will improve our ability as Physical Therapists to appropriately assess and provide successful treatment to our patient population.
Target Population:
This session will attract clinicians, educators and researchers interested in the impact of patients’ sleep cycle disruptions on their physical dysfunction and how to incorporate this knowledge base into best practices.
Description of Supporting Evidence:
OVERVIEW
Currently many people in our society are sleeping less than six hours a night. Research shows many important health effects related to sleep and sleep loss. Sleep is necessary for memory consolidation. Studies show that individuals do not recall new information as well if their sleep is disturbed either before or after learning tasks. Chronic sleep deprivation may cause weight gain as it alters the way our bodies process and store carbohydrates, and impacts levels of hormones that affect our appetite. Sleep debt contributes to a greater tendency to fall asleep during the day, which may cause mistakes such as medical errors, air traffic mishaps, and road accidents. Sleep loss results in irritability, impatience, inability to concentrate, and moodiness (Harvard Women’s Health Watch, January 2006). Serious sleep disorders - including Obstructive Sleep Apnea and Restless Legs Syndrome - have been linked to hypertension, increased stress hormone levels, and irregular heartbeat (Manconi et al, 2011).
It well known and documented that individuals with painful conditions often suffer from sleep disturbance and even sleep deprivation if the condition is chronic (Lavigne et al, 2011). As assessing and treating health professionals we must be aware of how this sleep disturbance can impact our patients’ ability to recover or manage their conditions, and how co-existing sleep disturbances of other origin in our patients may affect the success of our treatment plans and the patients’ progress and recovery.
OBSTRUCTIVE SLEEP APNEA
Sleep apnea is as common in our society as diabetes and hypertension. It affects at least 1 in 20 adults. It may cause a variety of symptoms including repeated nighttime waking, daytime sleepiness and non-refreshing sleep. OSA is more common in overweight individuals but can also occur in people of normal body weight. Adverse consequences include an increased risk of cardiovascular and cerebrovascular disease, and an increased incidence of motor vehicle accidents due to excessive sleepiness (Canadian Thoracic Society, 2011).
As primary healthcare professionals we cannot remain unaware of a condition of this significance, which has such broad health effects, and likely impacts many of our patient population. We must become more educated about this condition, be able to identify those individuals who may be yet undiagnosed and refer back to physicians for appropriate follow-up. Additionally, in understanding the impact of Obstructive Sleep Apnea in our patients who are diagnosed and under treatment, we can understand the role it may play in their symptom presentation.
RESTLESS LEGS SYNDROME
Restless Legs Syndrome is a sensory motor condition of unknown etiology that causes unpleasant and/or painful sensations in the legs (occasionally the arms). These sensations are worse in the evenings/night and with rest but can be eased with movement. RLS can seriously impact sleep and quality of life (Ekbom & Ulfberg, 2009). It occurs in approximately 10% of the general population (Michaud et al, 2002), 25-30% of patients with Chronic Obstructive Pulmonary Disease and up to 80% of individuals on Hemodialysis (Unruh, et al, 2004).
Restless Legs Syndrome is known to be under-diagnosed and under-treated (Allen et al, 2011). It is not unlikely that a significant number of physical therapy patients may be experiencing this condition. Common conditions, including neuropathy and radiculopathy, must be differentiated from Restless Legs Syndrome as these often present with similar symptoms (Ondo, 2007).
Exercise has been shown to be beneficial in ameliorating the symptoms of Restless Legs Syndrome in several populations (Sakkas et al, 2008, Aukerman et al, 2006, Esteves et al, 2008, Lettieri & Eliasson, 2008). One study has also shown Infrared Therapy to be of value (Mitchell et al, 2010). Once aware of this condition, Physical Therapists can have an important role in diagnosing Restless Legs Syndrome and providing appropriate education and treatment.
Description of Session Format:
This session will be presented in a lecture format, including representative case studies, with opportunity for discussion, questions, and practical assessment practice using validated screening questionnaires as an aid to learning.
Conclusions and Implications:
The importance of sleep and how it specifically relates to our clinical practice has not been the subject of a concerted focus for Physical Therapists to date. This educational session will provide physical therapists with an overview of potentially new knowledge of sleep. This knowledge will improve their ability to offer best, evidence-informed assessment and treatment approaches for conditions they currently treat and also conditions of which many may have previously been unaware.
