Registered outcomes20
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Change over time of the score on the Tinnitus Functional Index | Week 1, week 20, week 26, week 33, week 60 | A validated questionnaire which assesses the impact of tinnitus on a patient measured on multiple time points to measure a change over time. The TFI score can range from 0-100, higher values indicate more tinnitus burden. When a patient scores 54 or higher the tinnitus is considered to be a major problem. |
| Secondary | VAS Loudness | Week 1, week 12, week 20, week 26, week 33, week 60 | on a scale from 0 (no tinnitus) to 10 (most severe tinnitus imaginable), subjects rate their tinnitus perception on loudness. |
| Secondary | VAS Burden | Week 1, week 12, week 20, week 26, week 33, week 60 | on a scale from 0 (no tinnitus) to 10 (most severe tinnitus imaginable), subjects rate their tinnitus perception amount of discomfort. |
| Secondary | 15 word memory test | Week 1, week 27, week 34, week 60 | Participants are given a list of 15 unrelated words repeated over five different trials and are asked to repeat. Another list of 15 unrelated words are given and the client must again repeat the original list of 15 words and then again after 30 minutes. |
| Secondary | Boston naming test | Week 1, week 27, week 34, week 60 | The neurpsychologist shows the person each of the pictures, one at a time in the given order. The person is given 20 seconds to say what the drawing depicts. |
| Secondary | Stroop Color and Word Test | Week 1, week 27, week 34, week 60 | This is a neuropsychological test used to assess the ability to inhibit cognitive interference that occurs when the processing of a specific stimulus feature impedes the simultaneous processing of a second stimulus attribute, well-known as the Stroop Effect. |
| Secondary | Trail Making Test | Week 1, week 27, week 34, week 60 | This is a neuropsychological test of visual attention and task switching. It consists of two parts in which the subject is instructed to connect a set of 25 dots as quickly as possible while still maintaining accuracy. |
| Secondary | Semantic Verbal Fluency Test (Animals) | Week 1, week 27, week 34, week 60 | This is a test in which participants have to produce as many words as possible from a category, here animals. |
| Secondary | Semantic Verbal Fluency Test (Jobs) | Week 1, week 27, week 34, week 60 | This is a test in which participants have to produce as many words as possible from a category, here jobs. |
| Secondary | Phonemic Verbal Fluency Test (D) | Week 1, week 27, week 34, week 60 | This is a test in which participants have to produce as many words as possible from a category, here words starting with the letter D. |
