| Secondary | Quantitative Sensory Testing | A test where the assessor uses an algometer (i.e., handheld device that calculates the amount of force applied to the skin) to measure pressure pain sensitivity at 4 sites: upper trapezius, posterior superior iliac spine, greater trochanter, and tibialis anterior; higher values indicate higher pain thresholds, with values ranging from 0 to 10.1, where 10.1 indicates the participant tolerated 10 kilograms of force/cm squared without pain and therefore, no further pressure was applied. Pressure starts at 0.00 kilograms-of-force per square centimeter and is increased by 1-kgf/cm squared per second until the participant first experiences pain. | The number analyzed in one or more rows differs from the overall number analyzed because some participants withdrew from the study over time. | Posted | | Mean | Standard Deviation | kgf/cm squared | | Baseline, 8-weeks (i.e. post-intervention), and 6-months | | | | ID | Title | Description |
