Stories from the Front: Staying active

Carole Hartzman

Five mornings a week, Carole Hartzman and her exercise buddy take a 50-minute stroll along the waterfront. Twice a week, she attends a seniors’ fitness class.

Carole, 70, has always been physically active, but after she was diagnosed with Parkinson’s disease in November 2003 and evaluated at the Maritime Parkinson Physiotherapy Clinic in Halifax, she stepped up her exercise program and bought an elliptical trainer and universal gym machine to work out at home.

“I try to do three things a day. A walk, an exercise class and a session on the elliptical trainer. Or maybe sessions on both machines plus a workout video. Anything that catches me that day, I do it,” says Carole.

The benefits are immediate and wide-ranging. “You move. Keeping the core body firm and tightening it allows me to get up from my chair. The stronger the body, the stronger everything else. Everything works better if I’m strong.”

Carole now has difficulty sometimes initiating movement. “I freeze in place, so I have to think, how I am going to get started again? If I want to go from the stove to the refrigerator, I have to consciously tell myself, look at a point that’s closer to the refrigerator, pick up your left foot, now start moving it. Once I release that frozen state, I move, but I have to march myself through the steps.”

Knowing that the clinic will assess her mobility, flexibility and balance every six months, Carole says, “I want my score to be high, so I do my best to do well on those exercises. It’s a motivator.”

She credits the late Dr. George Turnbull, a co-founder of the clinic, with setting her on the right track. “He emphasized that you have to exercise and you have to choose activities you’re enthusiastic about because if you don’t, you won’t continue them.”

Carole enjoys dancing, has taken voice therapy and singing lessons, learned tai chi, and anticipates adding her recently-acquired Nordic walking poles to her morning walks. “I do whatever comes to mind to keep me moving.”

Having travelled extensively with her husband, Carole recently took a weekend trip to New York, on her own, deliberately requesting wheelchair assistance at the airport. “I wanted to see what it was like using a wheelchair. It was an interesting experience because, on the one hand, you think the wheelchair is going to make you feel debilitated but, on the other hand, it gave me the opportunity and freedom to travel by myself.”

Carole’s exercise goal is “to keep myself mobile forever so that I may continue to enjoy the world outside my home.”

Managing Parkinson’s symptoms with exercise

Janet Millar

Battling Parkinson’s disease? Fight back with exercise. That’s the message emerging from a growing body of research finding that people with Parkinson’s who exercise fare better over time than those who are not active.

“Exercise is not just beneficial for people with Parkinson’s, it’s essential,” says Janet Millar, Clinical Director and Physiotherapist at the Maritime Parkinson’s Physiotherapy Clinic in Halifax. “In our clinic, we tell people that exercise is as important as medication. We say this because recent literature suggests that exercise can and does improve Parkinson’s symptoms.”

Typical symptoms include slowness and stiffness, impaired balance, muscle rigidity and stooped posture. “These movement issues become impossible to deal with, at some point, if people with Parkinson’s do not keep themselves in good physical condition,” says Millar.

Noting that almost any kind of physical movement can be beneficial, if done properly, Millar recommends to her clients with Parkinson’s:

Exercise regularly, meaning daily. Make it challenging. “Those are the two criteria in which the literature tells us Parkinson’s can be slowed down.”

Focus on five key areas: endurance, flexibility, balance, posture, strength. “Walking is one of the most beneficial activities. It addresses several of those five issues and it provides opportunities to pay attention to stride length, gait pattern and arm swing, which are all affected in Parkinson’s.”

Emphasize the anti-gravity muscle group. “These are the muscles that straighten you or make you taller.” Back extensors, knee straighteners, triceps – the muscles at the back of the elbow that straighten the arms, enabling you to reach up, to the side and behind the back, shoulder blade squeezes. “These work against the typical stooped posture in Parkinson’s.”

Make exercise a lifelong habit. “There is something every single person can do – right from the person who can work out in the gym alongside everyone else to the person who may be confined to a bed and need extra support and intervention.”

Get active and stay active. People who enjoy group exercise can look for classes at community recreation centres. If not, they may find something they can do on their own or with a buddy. Millar: “Find physical activities that the person likes or will, at least, tolerate. I think that is the secret to compliance.”

PSC creates new Physical Activity and Parkinson’s Disease resource

Parkinson Society Canada, in partnership with the Canadian Physiotherapy Association, has created a new Physical Activity and Parkinson’s Disease tip sheet that explains why aerobic, strengthening, flexibility and balance activities are important in Parkinson’s and gives examples of activities within each category. It also includes a handy log to help you stay on track with your physical activity routines.

April 17 webinar on cognitive impairment and Parkinson’s

Parkinson Society Canada is hosting an hour-long free webinar on Cognitive Impairment and Parkinson’s disease, on Tuesday, April 17, 2012 at 1 p.m. EST.

In recent years, research has identified cognitive changes, such as dementia, depression and psychiatric symptoms, as part of the progression of Parkinson’s disease. This webinar provides an opportunity for both people living with Parkinson’s and health care professionals to recognize cognitive changes and learn how to manage them.

Dr. Oury Monchi

The presenter, Dr. Oury Monchi is an Associate Professor in the Department of Radiology at the University of Montreal. He also directs the Parkinson Cognition Action and Neuroimaging laboratory at the research centre of the Institut universitaire de gériatrie de Montréal. A major goal of his research is the early prediction of dementia in Parkinson’s and how it relates to that found in other neurodegenerative disorders.

You must register, in advance, online at www.parkinson.ca/webinar to participate in this live webinar.

This webinar is made possible through a Canadian Institutes of Health Research Knowledge Translation Grant.

Can exercise help improve cognition, language, voice or swallowing in Parkinson’s?

Exercise is accepted as a part of a healthy lifestyle. Of late, researchers are questioning the value of exercise in actually preventing and slowing the progression of Parkinson’s disease.

Traditionally the role of exercise has fallen under the realms of physiotherapy, occupational therapy and nursing. However, new research suggests that exercise may have a role in remedying areas that speech-language therapy traditionally targets, such as cognition, language, voice and swallowing in Parkinson’s.

Cognition and language

Cognitive impairment is a Parkinson’s symptom with substantial effects on quality of life. Cognitive changes may begin early in the disease and may even precede motor symptoms for some people. These changes may affect language functions in ways that are evident on language assessments and particularly noticeable in conversation and in dual-tasking activities such as walking and talking.

While there is research showing that exercise is beneficial for cognition in Alzheimer’s disease, to date, there are no large randomized controlled trials to help answer this question in Parkinson’s. However, a few studies provide some insight into the potential benefits of exercise on cognition and language in Parkinson’s.

  • Nocera, et al. (2010) reported the case of a woman with Parkinson’s who showed improved cognitive and language function following an exercise program that included 20 minutes of stationary bike riding, three times a week for eight weeks. In addition to substantial gains in executive function, working memory and verbal fluency, the researchers reported language improvements, such as more efficient and effective communication. The subject produced fewer grammatical errors and showed an impressive reduction in fluency interruptions and fillers (e.g., “uh”; “um”), which may reflect a reduction in word retrieval difficulties.
  • In a study published by Cruise, et al. (2011), 34 people with Parkinson’s were allocated to either an exercise group or a control group. The exercise group participated in a 60-minute exercise session (cardiovascular and strength training) twice a week. In cognition and language areas, such as spatial working memory, verbal fluency and semantic fluency, the researchers reported that the exercise group showed gains that met statistical criteria for clinical substantial benefit.

These studies suggest a potential benefit of general exercise on cognition and language that is worth further investigation.

Voice and swallowing

Angela Roberts-South and Professor Scott Adams work at the University of Western Ontario on techniques to optimize communication for individuals with Parkinson's disease

Voice and swallowing problems are common in Parkinson’s. There are no published studies evaluating the effect of general physical exercise programs, such as cardiovascular and strength training, on improvements in voice and swallowing in Parkinson’s. However, Russell, et al. (2010) published an excellent comprehensive review of targeted exercise programs in Parkinson’s. General physical exercise programs do not target a specific muscle group or motor target. Russell, et al. defined targeted physical exercise as the “systematic, repeated and controlled activation of particular groups of muscles for particular sequences of goal-directed actions.”

  • Lee Silverman Voice Treatment® (LSVT) is probably the most prominently reported targeted exercise program. It is an intensive exercise program performed by an LSVT-certified therapist. It involves following a prescribed exercise and stimulus protocol targeting the laryngeal and respiratory systems and mouth opening. Many studies have reported the benefits of LSVT on voice intensity. Recent research suggests that LSVT may also benefit swallowing (Sharkawi, et al., 2002).
  • Expiratory Muscle Strength Training (EMST), developed by Dr. Christine Sapienza, is another targeted exercise program. (The expiratory muscles are used in coughing.) EMST uses a specially-developed device and a prescribed exercise program to improve expiratory muscle function, which may have benefits for respiration and swallowing in Parkinson’s (Saleem, et al. 2005, Pitts, et al. 2009, Troche, et al. 2010). While EMST requires a special device, it can largely be completed at home unsupervised. A therapist is needed to calibrate the device and evaluate or re-set therapy targets.

Outside of LSVT and EMST, the literature on targeted, systematic exercise programs for voice and swallowing in Parkinson’s is sparse. There are other exercise programs reported in the literature but they have either failed to meet expected gains or failed to demonstrate carryover into functional activities. This makes it difficult for health professionals to apply them effectively in clinical settings.

Summary

There is a shortage of evidence on the benefit of exercise programs for cognition, language, voice and swallowing in Parkinson’s. Exercise targets, intensity and duration differed in the studies reviewed, however, there were some promising improvements in cognition and language with general exercise/fitness programs. As well, certain targeted exercise programs appear to demonstrate benefit.

Physical exercise programs are not often considered a companion to traditional speech-language therapy in Parkinson’s. However, it is possible that, as more research is completed, speech-language pathologists may need to increase their knowledge of both the application and development of targeted exercise programs and their knowledge of the adjunctive benefits of general physical exercise so they can incorporate it into therapy plans for people with Parkinson’s.


Challenges with movement only half the story in Parkinson’s

New Handbook reveals the non-motor side

Toronto, March 21, 2012 – People with Parkinson’s disease have a new tool to help them identify the non-motor symptoms they are experiencing with their Parkinson’s disease.

A Guide to the Non-Motor Symptoms of Parkinson’s Disease, the first of its kind in Canada, is a user-friendly, educational booklet, designed to help people with Parkinson’s recognize non-motor symptoms such as cognitive impairment, sleep problems and compulsive behaviours and learn about treatments and strategies to manage them.

The 50-page booklet, available in English and French, is the result of a partnership between Parkinson Society Canada and the CIHR Institute of Neurosciences, Mental Health and Addiction. The author, Dr. Ronald Postuma is a researcher in neurosciences at the Research Institute of the McGill University Health Centre (MUHC) in Montreal.

Dr. Ron Postuma

Citing a typical example, Dr. Postuma says a man with Parkinson’s may present with a urinary problem that is initially thought to be a prostate issue when, in fact, it may be related to Parkinson’s. “Many patients do not realize that urinary problems, constipation, insomnia and other symptoms are linked to Parkinson’s disease. As a result, they go untreated,” says Postuma who is also a neurologist at the MUHC and an Associate Professor of Neurology and Neurosurgery in the Faculty of Medicine at McGill University. “The booklet is a simple, pragmatic tool that I hope will improve patient care,” he added.

Postuma says that the booklet is intended to help people with Parkinson’s identify their non-motor symptoms, record what they are experiencing using the Non-Motor Symptoms Questionnaire at the back of the booklet, and discuss these symptoms with their doctor. He cautions it is not intended to replace the advice or instruction of a professional healthcare practitioner, or to substitute medical care.

“This is an excellent example of the practical application of evidenced-based research that benefits clinical care,” says Joyce Gordon, President  & CEO, Parkinson Society Canada.

A Guide to the Non-Motor Symptoms of Parkinson’s Disease is available at www.parkinson.ca/NonMotorGuide.
