Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Dix-Hallpike test (DHT) | At 7th day | percentage of negative DHT between single and multiple cycles |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Loss of balance | compare to the first visit at 28th day between single and multiple cycles | 5 levels Level 1: Able to continue daily activities without any helps. Level 2: Able to continue daily activities without any helps except complicated activities such as riding a bicycle, walking on counterpoise or scaffolding. Level 3: Not able to continue daily activities without help excepts simple activities such as self-care, housework, walking, or being a passenger in a vehicle Level 4: Not able to continue daily activities alone without help except self-care Level 5 Not able to continue daily activities alone without help except self-care without ambulation. Need to stay only in a house or a living place. (From: The Royal college of Otolaryngologists head and neck surgeons of Thailand, and social security office of thailand) |
