arm pain

As Parkinson’s disease (PD) progresses, it is common to experience changes in the spine, hands and feet.

Parkinson’s disease pain is divided into five categories:

  1. Musculoskeletal: pain that affects the bones, muscles, ligaments, tendons and nerves. It can occur suddenly or be long-lasting and can occur in one area or several.
  2. Neuropathic/radicular: chronic pain condition there the body sends pain signals to the brain, not caused by an injury.
  3. Dystonic: sustained or repetitive muscle twisting, spasm or cramp that can occur at different times of day and in different stages of Parkinson’s.
  4. Akathisia: causes the feeling of restlessness or inability to be still
  5. Central pain: neurological condition caused by a dysfunction that affects the central nervous system and is resistant to treatment.

Nearly every person who lives with PD will experience some degree of muscle rigidity. Muscle rigidity associated with PD is most noticeable in the muscles that flex the limbs and trunk. Common experiences include bending of the neck, curling of the trunk with slumping of the shoulders and bending at the wrists, fingers, elbows, hips and knees. These changes progress over time.

A third or more people with PD eventually experience changes in posture, although this occurs most often in advanced PD. Some people experience severe postural changes with extreme leaning forward or to one side.

Other common changes include dystonia, muscle spasms and cramps that are particularly common in the feet; and osteoporosis, where weakened bones which can increase risk of falls and fractures. Lastly, it is important to look at the impact of orthopedic surgeries for non-PD related spine deformities, hip and knee replacement and other bone problems, which may present unique challenges for people with PD. Although people with PD can benefit from such surgeries, they may have a longer and more complicated recovery than people without PD.

Rigidity, weakened muscles and involuntary muscle contractions (dystonia) can cause painful deformities for people with PD. A tilted or twisted spine also can throw a person off balance and increase the risk of falling. These common changes in the skeleton and bones can occur with PD:

  • Frozen shoulder: stiffness, pain and loss of range of movement in the shoulder, many people experience this symptom before a PD diagnosis.
  • Flexed fingers or toes (striatal hand and foot): one finger may extend, the thumb may fold inwards, fingers may clamp down onto the palm and on the foot, the big toe may flex upward while other toes curl under.
  • Stooped posture (camptocormia): the spine bends forward when walking, in the most severe cases as much as 90 degrees. This posture arises because the hips and knees are flexed and will go away when lying down.
  • Leaning sideways (Pisa syndrome): involuntarily tilting of the trunk to one side when sitting, standing or walking; always to the same side
  • Scoliosis: sideways twisting, or curvature, of the spine.
  • Dropped head (anterocollis): the head and neck flex forward; the chin may drop all the way down to the sternum, or breastbone (more common in multiple system atrophy than PD).
  • Bone fractures: people with PD are at risk of broken bones from falling, especially from landing on the hip; and kneecap fractures also are common, painful and sometimes not diagnosed.
  • Low bone density: bones may become weak and at risk for osteoporosis from lack of weight-bearing exercise, like walking, and from too little calcium and vitamin D. Other risk factors for osteoporosis include older age, gender (females > males), low body weight, and smoking. A person with PD who has osteoporosis is more likely to break a bone if they fall.

Other Symptoms: Aging or PD?

Because the biggest risk factor for developing PD is age (the average age of diagnosis is 60), skeletal problems associated with aging are often experienced by people with PD. While it is not clear that PD increases the risk or even the severity of these other skeletal conditions, the problems of PD can make the symptoms of these conditions more prominent.

  • Osteoarthritis, the joint damage associated with general wear and tear on the joints, is nearly universal in aging. Osteoarthritis tends to affect larger joints such as the hip and knee.
  • Arthritis of the spine is also very common. This may contribute to the development of spinal stenosis, narrowing of the canal in the spine that houses the spinal cord. In severe cases, spinal stenosis causes damage to the nerves as they exit the spine or even to the spinal cord itself. 
  • Disorders of the fibrous discs between the bones of the spine can also cause pain, or limb numbness or weakness.


Medical therapies can help relieve the rigidity and muscle contractions that contribute to changes in posture. The approach to therapy very much depends on a person’s unique symptoms and overall health. Your doctor may advise:

  • Dopamine: the gold-standard medication for PD movement symptoms, carbidopa/levodopa (most often prescribed as Sinemet®). If you do not already take dopamine, starting on this drug may improve symptoms like stooped posture and help prevent them from becoming permanent. If you already take dopamine, review your dose and medication schedule with your doctor to be sure it is working well.
  • Botulinum injections (Botox®): these injections relax muscles that are flexed or having spasms. They are typically used in specific areas that are affected, such as the hands, feet and neck, but not in larger muscles involved in postural abnormalities of the trunk.
  • Deep brain stimulation (DBS): this is a surgical procedure which may offer benefit for certain types of muscle contractions
  • Surgery: Surgical therapies (joint replacements, spinal surgery) may be required to treat significant osteoarthritis, disc disease or spinal stenosis. As with any surgical treatment, the risks and benefits should be weighed carefully.

Tips for Maintaining Healthy Bones

  • Talk to your doctor about your PD medication regimen — medication changes that may ease skeletal/spine issues and strategies for optimizing medications to ensure they are most effective for PD.
  • Ask your primary care doctor about having your bone-mineral density tested. If it is low, medications are available to help maintain or increase it.
  • Discuss testing your blood level of vitamin D with your physician. If it is low, follow your doctor’s advice on taking supplements.
  • Reduce the risk of falls by making the home safer with the advice of an occupational therapist and using the correct assistive devices (including different types of walkers or canes) when needed as instructed by a physical therapist
  • Get active and keep moving. Exercise helps maintain strong bones and can ease dystonia among other symptoms. There is no gold standard exercise — whatever you enjoy and can do is the right exercise. Try to be active at least 30-45 minutes daily. Walking, swimming, yoga, Tai Chi, dancing, etc. are all good choices.
  • See a physical therapist for advice on how to stretch, strengthen and relax your muscles and for a program of exercises tailored to your own PD symptoms.
  • Ask your doctor about detecting changes in posture early, when they can be treated and before they become permanent.
  • Visit your doctor for regular physicals to rule out causes of pain unrelated to PD or changes in the spine unrelated to PD.
  • Alternative or complementary therapies may be helpful in some cases. For example, acupuncture or massage can help some people with pain and may be considered.
