Yoga for Parkinson’s: Research Suggests many Benefits
Tuesday, 10th January 2017

Yoga continues to rise in popularity and is cited as a favourite non-medical therapy by many living with Parkinson’s disease. Getting started can seem challenging, as it is often portrayed with pretzel-like contortions and trendy #yogaselfies on social media. But, yoga is an adaptable practise, with both functional and psychosocial benefits, that can be suited to a variety of abilities.

Yoga has become synonymous with holding and moving between a series of static postures (called asanas); however, this physical practice (called hatha yoga) is only one part of the larger yoga framework that includes branches such as philosophy, chanting and selfless service. Hatha yoga combines physical postures to address strength, flexibility, balance and mind-body-breath connection. Breathing practices (pranayama) and meditation are included to develop greater self-awareness.

What do we know about yoga for people with Parkinson’s?

In looking through the scientific literature, there are a few studies that support hatha yoga for persons with PD. This is clearly an area of research that is just starting to gain ground. What studies do exist suggest modest benefits for:

Mobility. The issue of mobility has important implications for falls in PD. Yoga participation can improve functional mobility and how a person with PD walks. Standing yoga poses target the hip extensor, knee extensor and ankle plantar flexor, which support center-of-mass during walking and may improve overall stability.

Balance. Balance training is an important component of PD therapy, as 40 percent of nursing home admissions are preceded by a fall. Research shows yoga-related improvements in balance (tandem, one-leg) and an associated reduction in fear of falling; this can also help keep people with PD active in their community.

Strength. Gains in lower-body strength occur for PD patients following yoga practice and are associated with improved postural stability. Yoga requires isometric contraction (i.e., the joint angle and muscle length do not change) of specific muscle groups to stabilize the body as one performs the postures, and may mimic isokinetic contractions (i.e., variable resistance to a movement performed at constant speed) when performing controlled systematic movements from one pose to the next. These mechanisms may be the reason why yoga improves muscular strength.

Flexibility. Improvements in flexibility and range of motion (ROM) are important since rigidity is a common clinical manifestation in PD. Research shows improvements in flexibility/ROM of the shoulder, hip and spine. Stooped posture is characteristic in PD and can be related to short spinal flexors and weak spinal extensors; improved shoulder and spinal flexibility from yoga supports a more upright posture. Greater hip mobility from yoga may translate into improvements in shuffling gait experienced by many living with PD.

Mood & Sleep. The psychosocial benefits associated with yoga are important for disease management, as they are not often addressed with conventional dopaminergic therapy. Yoga can offer group support, improved confidence and self-efficacy. The calming effect of yoga (by enhancing parasympathetic output) may lessen perceived stress, enhance relaxation, and benefit sleep in PD.

Roland who completed her PhD research at the University of British Columbia (2012), which measured Parkinson’s disease (PD)-related changes to daily muscle activity and consequences for physical function and frailty. She is currently a postdoctoral fellow at the University of Victoria¹s Centre on Aging and her most recent work examines care needs and well-being in PD dementia caregivers. Kaitlyn offers yoga workshops to persons with PD called “Yogadopa” and blogs about Parkinson’s, aging and yoga-related information at https://yogadopa.com. Overall, she aims to support independent living, and reduce distress and healthcare utilization in persons with PD, dementia and their caregivers.
