WHAT CONDITIONS DO WE TREAT WITH DBS?
FDA Approved Indications: Parkinson’s disease (PD) – STN or GPi Essential Tremor (ET) - VIM Dystonia (Cervical or Generalized) - GPi Obsessive Compulsive Disorder (OCD) Epilepsy (Anterior Nucleus of Thalamus)
Shukla & Okun 2016
What is Parkinson’s disease?
5
PD Clinical FeaturesPD Clinical Features
• Onset: insidious,
• unilateral progressing to bilateral
• Cardinal signs
• (motor symptoms)
• Bradykinesia*
• Resting tremor
• Rigidity
• Loss of postural reflexes
• 60-80% Dopaminergic
neuronal cell loss in PD
occurs before symptoms
appear
• Non-motor features may
predate the onset of
classic motor symptoms

Bradykinesia
Slowness of movement. Associated with Parkinson’s Disease.
Video
Rest Tremor
Involuntary rhythmic oscillation of a limb at rest, diminishing with action. A cardinal sign of Parkinson’s disease.
video
Loss of Postural Reflexes
Retropulsion, inability to “right” oneself when force is used to require a stepping response. A cardinal sign of Parkinson’s disease.

Dyskinesia
Abnormal involuntary movements that occur in response to dopamine therapy. “Choreiform” movements.

PD Considerations
1. Provide PD meds on time, every time.
2. Do not substitute medications.
3. Do not stop Levodopa therapy abruptly.
4. Resume meds when able.
5. If antipsychotic is needed, use Quetiapine or Clozapine.
6. Watch for symptoms of dysphagia and risk for pneumonia.
7. DBS needs to be turned off for surgery, MRI, EKG, EEG or EMG.

What is Essential Tremor?
Essential Tremor
Most common movement disorder
Commonly inherited
Primarily kinetic tremor during voluntary movement, may rarely be present at rest, or with holding postures
Tremor frequency of 4-10 Hz with variable amplitude
Can involve head and vocal cords
Increases with stress
Relieved for short periods by Alcohol
Can see a mild ataxic gait

Postural (Action) Tremor
Involuntary rhythmic oscillation of a Limb being held in a posture against gravity.
Video
Kinetic (Action) Tremor:Simple kinetic tremor, task specific tremor,
intention tremor and isometric tremor
(typically seen in ET)

What is Dystonia?
DYSTONIA
Consensus Definition 2013:
• “Dystonia is a movement disorder characterized by sustained or intermittent muscle contractions causing abnormal, often repetitive movements, postures, or both.
• Dystonic movements are typically patterned, twisting, and may be tremulous.
• Dystonia is often initiated or worsened by voluntary action and associated with overflow muscle activation.”
Albanese, Bhatia, Bressman, et al. Movement Disorders.2013;28:863-873
Dystonic Tremor
Dystonic tremor is an action tremor that may be postural, kinetic or both. This tremor is asymmetric, jerky and irregular.

DBS Patient Education
• Remind patient that DBS is not a cure (Shukla 2016)
• Remind patient to continue to take medications
• Inform patient that they might be able to lower dose of medication by 25-50% (Shukla 2016)
• Optimal results can take months and will be different for each patient
• DBS Settings and medications are adjusted concurrently
• DBS is a process (Revell 2015)
• Cognition, speech, gait dysfunction, depression, anxiety and postural instability do not respond to DBS (Martinez-Ramirez 2014)
Bautista C*, Miravite J*, Coronel H, Hunt D, and Dallow E. (2019) Evidence-Based Strategies for Care of the Patient with Movement Disorders and Deep Brain Stimulation. Chicago: American Association of Neuroscience Nurses
• Wash hands frequently & any time before touching surgical incisions while healing.
• Look for signs and symptoms of wound infection or skin erosion.
• Change dressings as instructed.
• Refrain from picking, scratching, or unnecessarily touching incisions.
• Call the neurology or neurosurgery office for any erythema, bleeding, purulent discharge or drainage, edema, tenderness, warmth, delayed healing, discoloration, or fever greater than 101°F.
Post DBS Wound Care
Bautista C*, Miravite J*, Coronel H, Hunt D, and Dallow E. (2019) Evidence-Based Strategies for Care of the Patient with Movement Disorders and Deep Brain Stimulation. Chicago: American Association of Neuroscience Nurses
There are several reasons to call the office.
Ensure that the patient has reviewed the following:
• Headache, weakness, and change in speech or gait
• Abrupt return of symptoms
• Worsening of symptoms
• Burning sensation along the DBS hardwareBautista C*, Miravite J*, Coronel H, Hunt D, and Dallow E. (2019)

Non-pharmacologic Considerations in Movement Disorders
Physical therapy
Goals:• Improve motor function• Increase range of motion• Build endurance
Techniques: counting steps, marching, visual fixation, balance training
Can be helpful for symptoms such as stooped posture, shuffling and other gait disturbances, difficulty rising from chairs
Occupational therapy
Concentrates on fine finger and hand movements Techniques: adaptive equipment, energy conservation,
range of motion
Speech therapy
Concentrates on speech impairments and swallowing difficulties
Techniques: voice projection and vocal exercises
Diet Patients should maintain a well-balanced diet Meals rich in protein may reduce absorption of levodopa
