This study aims to compare Botox injections without Physical Therapy sessions to Botox injections combined with Physical Therapy sessions for treatment of Cervical Dystonia. It is expected that Botox combined with Physical Therapy will improve Cervical Dystonia symptoms and quality of life more than Botox alone. It is also expected that Botox combined with Physical Therapy will enhance neuroplasticity, or the ability of the brain to make new connections, more than Botox alone at 4-5 weeks, and remain improved at 12 weeks, after Botox injection.
The study will recruit primary cervical dystonia patients (age 18-80) who are stable on Allergan botulinum toxin type A (Botox). Patients will be randomized to receive their typical Botox injection alone, or with physical therapy.
At Baseline, disease characteristics (as measured by the Toronto Western Spasmodic Torticollis Rating Scale, or TWSTRS, and the Clinical Global Impression of Severity, or CGIS) will be measured, along with quality of life (from the Short Health 36 Survey Form 36, or SF-36). One subscale of the TWSTRS will be videotaped to be later evaluated by blinded movement disorder specialists. A pain scale will also be completed and range of head motion will be measured using a device similar to a protractor (called a goniometer). An individualized Botox injection will be administered, as well as transcranial magnetic stimulation (TMS) to measure neuroplasticity, or the ability of the brain to make new connections. If randomized to receive physical therapy, participants will also receive instructions to perform physical therapy exercises five times per week by a physical therapist who specializes in movement disorders. The investigator will call weekly to check how the participant is doing with the exercise program.
The same procedures outlined above will also be performed at 5 weeks past baseline, and at 12 weeks (except for the Botox injection, which will only be given at baseline and 12 weeks).

| Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) | The Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) is a measure of symptoms, pain, and disability related to Cervical Dystonia. The total TWSTRS scale includes a global outcome score (total score) and scores on each of 3 subscales for severity (0-35), disability (0-30), and pain (0-20), which are summed together for a total score (0-85), with higher scores indicating greater impairment. The TWSTRS is completed by a neurologist who visually assesses the patient's symptoms, and asks the patient to self-report on pain and disability. | absolute value at Week 12 |
| SF-36 Physical Functioning Subscore | The Short Form 36-Item Health Scale (SF-36) is a health survey with 36 questions that is self-reported by the study participant. It contains 8 subscales, one of which is Physical Functioning, calculated from 10 of the 36 questions. Different questions have different score ranges and valences. Therefore, their response for each question is linearly transformed to a value of 0-100 (for example, choosing response 3 on a scale of 1-5 is transformed to 60). These ten values are then averaged to generate the Physical Functioning subscore, ranging from 0-100. The higher the response value and the subscore, the higher degree of physical functioning. More details on RAND SF-36 scoring here: https://www.rand.org/health-care/surveys\_tools/mos/36-item-short-form/scoring.html | absolute value at Week 12 |
| Clinical Global Impression Scale (CGIS) | This scale is an investigator-rated scale that measures illness severity on a single 7-point scale (1-7). Higher scores represent greater severity of illness. | absolute value at Week 12 |
| Measure | Description | Time Frame |

| Mean MEP After Paired Associative Stimulation (PASmean) | A standard transcranial magnetic stimulation (TMS) paired associative stimulation (PAS) protocol was used to measure of neuroplasticity (the ability of the brain to form new connections). A nerve stimulator was placed on the wrist of the right hand to stimulate the median and ulnar nerves, set at the lowest intensity where the right thumb begins to twitch. An EMG sensor was placed over the abductor pollicis brevis muscle to measure muscle contractions. A magnetic coil was placed on the scalp on the left side of the head, overlying the brain's motor cortex, to stimulate the brain's output to the muscles in the opposite hand. 90 pairs of TMS and nerve stimulator pulses were applied. Then the motor evoked potential (MEP) from a single TMS pulse recorded from the surface EMG of the abductor pollicis brevis muscle was determined immediately, at 15 min and at 30 min after completion of the PAS protocol. The mean of these MEPs (PASmean) was compared between baseline and followup. |

Participants will be asked to sit in a chair and move the head to the left, to the right, to the front, and to the back. Then, participants be asked to tilt the head from side to side. A goniometer will be used to measure how far the head is able to move. The goniometer is similar to a protractor that measures magnitude of angle. A greater number indicates a greater range of motion. The minimum score would be 0, with no definite maximum (would not clinically be expected to exceed 70 degrees).
