Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) Primary · Before rTMS (Session 1: Week 9, Session 2: Week 21), Immediately after rTMS (Session 1: Week 10, Session 2: Week 22), 2 weeks after rTMS (Session 1: Week 12, Session 2: Week 24)

This is an objective scale evaluating patients on a variety of features including maximal excursion, duration, effects of sensory trick, shoulder elevation, range of motion, and time. Scores range from 0 to 85 where a higher score indicates more severity.

This is a 21-question survey evaluating depression in patients on a 0 to 3 scale, with a minimum score of 0 and maximum score 63, and higher score indicating a higher level of depression.

Patients are instructed to connect circles in ascending numerical order and are scored on how quickly they are able to complete the task. A longer amount of time indicates more severe cognitive impairment (in general, more than 78 seconds to complete Part A is considered impaired).

Patients are instructed to connect circles in ascending numerical order and are scored on how quickly they are able to complete the task. A longer amount of time indicates more severe cognitive impairment (in general, more than 273 seconds to complete Part B is considered impaired).

Wisconsin Card Sorting Task (WCST) - %Total Errors Secondary · Before rTMS (Session 1: Week 9, Session 2: Week 21), Immediately after rTMS (Session 1: Week 10, Session 2: Week 22), 2 weeks after rTMS (Session 1: Week 12, Session 2: Week 24)

The Wisconsin Card Sorting Test is a test of rule-learning and conceptual flexibility. The participant is required to learn to sort a series of cards according to one of three principles (color, form or number) based on response feedback. This measure is computed by calculating the ration of total errors to trials administered and multiplied by 100.

The Wisconsin Card Sorting Test is a test of rule-learning and conceptual flexibility. The participant is required to learn to sort a series of cards according to one of three principles (color, form or number) based on response feedback. This measure reflects the "density" of perseverative errors in relation to the overall test performance. It is computed by calculating the ration of total errors to trials administered and multiplied by 100.

Sponsor's own description

We applied 16 sessions of rTMS over 4 consecutive days for adult patients suffering from cervical dystonia who received botulinum toxin (BoNT) injections on a regular basis. The TMS protocol took place 9 weeks following their last BoNT injection. The primary outcome measure was improvement in cervical dystonia as measured by the TWSTRS scale. The secondary outcome measures included mood, cognition, and gait measures.
