Welcome back, fighters! Continuing with our bone related issues, we will now examine a relatively common problem in people living with Parkinson’s Disease, Pisa Syndrome.


Pisa Syndrome, also known as Pleurothotonus, affects the spine and is defined as a lateral bending of the trunk with a tendency to lean to one side. Pisa causes changes in the spine such as narrowing of the central spinal canal through which the spinal cord travels leading to stenosis, poor posture and instability.


It is not uncommon for Pisa and Scoliosis to be considered the same problem. However, they are not. A person living with Pisa will “list” to one side, while a person living with Scoliosis will have a curvature to their spine and rotation but not necessarily a lateral bend.

What causes Pisa Syndrome?


It is likely that Pisa is multifactorial, meaning many factors may influence the development of and severity of Pisa Syndrome. We think there is a central (brain and spinal cord) and peripheral (everything else) component to Pisa Syndrome. Central mechanisms consisting of basal ganglia dysfunction (dystonia and rigidity), abnormal sensory integration, and/or cognitive dysfunctions affecting perception and postural control. Peripheral mechanisms consisting of alterations of the musculoskeletal system (myopathy, soft tissue changes, etc.).


Others hypothesize that due to medication changes or the increase of the dose of dopaminergic medications, the likelihood of onset becomes higher. Other scientists think that as basal ganglia dysfunction increases, so do the chances of Pisa (Tinazzi et al., 2019; Artusi et al., 2019).


Is Pisa Syndrome neurological AND bone-related?

Yes! Because Pisa is associated with basal ganglia and sensorimotor dysfunction, there is a high likelihood of the onset of Pisa along with other movement disorders such as idiopathic Parkinson’s (80% of the Parkinson’s population) and Alzheimer's and atypical Parkinson’s syndromes (20% of the Parkinson’s population) such as Multiple Systems Atrophy, dementia with Lewy Bodies, Progressive Supranuclear Palsy (Castrioto et al, 2014; Barone et al., 2016).


Although Pisa syndrome is usually classified as a neuromuscular disorder, the spine is greatly affected due to favoring one side, leading to postural abnormalities. This, in turn, can affect not only muscular health and movement, but also bone health. Bad posture, overcompensation for balance to one side, issues such as falling, and increased risk for osteoporosis may be more likely to occur in those individuals with Pisa, resulting in the likelihood of bone fractures and overall decreased bone health (Barone et al., 2016).


Medication awareness.

Moving on, let’s investigate how medication may affect Pisa Syndrome. Although there are studies correlating the use of dopaminergic drugs, there is no longitudinal or concrete evidence stating that medication causes Pisa syndrome (Castrioto et al., 2014; Barone et al., 2016; Tinazzi et al., 2016). However, it is known that incorrect dosages, either too high OR too low, can affect the onset of this disorder (Castrioto et al., 2014; Tinazzi et al., 2016). Therefore, it is imperative that your providers assess the correct dosage, and that medication is taken consistently to lessen chances of this syndrome.


Some medications that may contribute to the onset of Pisa syndrome include dopaminergic medications such as carbidopa-levodopa (Sinemet or generic), dopamine agonists such as ropinirole, or anticholinesterases such as donepezil. This may sound scary, but it is important to note that Pisa can be treated by adjusting your PD medications, so make sure to check in with your doctor if you are experiencing Pisa symptoms. Do not stop taking your Parkinson’s medication and keep your care team in the loop at all times!


The Effect of Pisa Syndrome On Parkinson’s Disease

Now that we’ve looked at Pisa from a scientific perspective let’s address how Pisa Syndrome affects activities of daily living and Parkinson’s Disease.

  1. As mentioned earlier, Pisa Syndrome essentially causes changes in the spine which leads to poor posture and instability and causes the following:

  • The head may droop,

  • The neck moves forward rather than remaining in alignment with the spine.

  • The shoulders round causing a forward slump that affects the amount of space for your internal organs.

  • Breathing becomes shallow and/or more labored.

  • Movement through the hips and spine decreases which affects gait length and increases risk of falls.

The above postural changes can impact one in the following ways:

  • Neck/Jaw pain and headaches due to muscle tightness

  • Loss of sleep

  • Digestion disruption due to organs being compressed

  • Depression

  • Poor circulation

  • Constricted nerves

  • Foot pain due to misalignment

  • High blood pressure

Sensory Components of Pisa

Here we see how the three balance systems are impaired .

  • Vision:

    • Impaired perception of vertical (vertical can deviate either towards or away from the side the body tilts)

  • Proprioceptive:

    • Unbalanced proprioceptive feedback (body awareness in relation to space and time)

  • Vestibular:

    • Unilateral or possible bilateral vestibular hypofunction


Treatment for Pisa Syndrome


Now, let’s consider some of the activities a person does in one day - walking, bathing, dressing, cleaning, laundry, caring for children/spouse/pets, cooking, driving, social events

We don’t have any concrete data on if/how Pisa affects Parkinson’s severity, but we can see from the above how it may affect Parkinson’s symptoms. So, how can we treat Pisa? Let’s have a look.

  1. Medication - Speak to your physician! Review your medications to see if changes in dosage or type of drug may be initiating or aggravating the syndrome.

  2. Reducing Fall Risk - Pisa Syndrome can increase your risk of falls secondary to a lateral trunk lean which results in a change in the center of gravity and inadequate trunk control. As such, one should seek a comprehensive evaluation aimed at eliminating risk factors for falls, improving postural awareness, strength/mobility training, and/or offering effective preventive measures to reduce fall risk. This can be performed by a multidisciplinary team consisting of your physician, personal trainer, and physical therapist. Additionally, a major goal of PT is improving midline awareness and making sure that their curvature does not worsen.

  3. Exercise- Addressing your core through exercises that involve vertical and lateral challenges provide the most benefit. While we can NOT change the shape of the spine, we can strengthen the muscles that support the core!

    • Rows

    • T’s

    • Front Lateral Pulldown

    • Shrugs (standing upright)

    • Modified Cobra (hands on the kitchen counter or ballet barre to protect those with Osteoporosis and Osteopenia

    • Tube rotation exercises

    • Isometric tube exercises

    • Stretching to maintain spinal mobility

    • Trunk alignment and midline orientation exercises

    • Physical Therapist to assess for somatosensory integration deficits including:

      • Vision

      • Vestibular

      • Proprioceptive

Watch the video demonstration below to learn how to properly perform these exercises.



Bridges For Parkinson’s includes these exercises in the warm-up and strength portion of our routines each week.

Note: Some may need individualized physical therapy to provide postural exercises, reduce lumbar pain, and provide preventative exercises.


In closing, Pisa Syndrome is unique in that it develops over time in conjunction with a movement disorder. The strength of your physical structure depends on having the knowledge to identify possible bone issues such as Pisa Syndrome, properly addressing the issue with corrective exercises and a team that provides support and encouragement.


Bridges For Parkinson’s is focused on helping our fighters and care-partners develop a sense of awareness, provide corrective exercise therapy for those dealing with Pisa Syndrome or preventative exercises to support a strong, vertical spine!


If you are concerned about recent postural changes, please do not hesitate to reach out to Coach Colleen, Coach Cindy (Physical Therapist), or Coach Megan (Physical Therapist) for a consultation. If you are experiencing frustration with your daily activities and need assistance with tips for daily tasks, Coach Caitlin (Occupational Therapist) or Coach Becca (Occupational Therapist) are more than happy to help you!


Together, we fight back stronger!
