Data repository - handheld dynamometry in individuals with symptomatic hip osteoarthritis.

This is the raw data of a study intended to evaluate the reliability of a handheld dynamometer in individuals with hip symptomatic hip osteoarthritis. Data is composed of one file with six folders. First, the Demographic Data of participants are present (non-identify data), followed by strength measures (peak force, time to reach peak force, and average peak force) regarding hip flexors, abductors, adductors, and extensors. Lastly, the Visual Analog Scale for pain is presented at the eligibility moment and after each strength measurement performed. The HHD Lafayette Manual Muscle Testing System Model-01165 (Lafayette Instrument Company, Lafayette IN, USA) was used to assess hip muscle strength during a three-second maximal effort, following the protocol sequence: hip flexors (seated position), hip abductors, and adductors (supine, long-lever), and hip extensors (prone, long-lever) performed on a regular examination table and collected on the same day by both raters. Two independent raters performed data collection, both physicians with no experience with the HHD. Raters were allowed to practice the measurements protocol sequence for four months. Each rater repeated measurements twice on the same day. Participants were allowed to rest between each protocol sequence until they felt comfortable to start the next round. The VAS for pain was measured after each sequence. Participants were given continuous encouragement to push harder against the HHD to obtain maximal isometric force during the 3 seconds of each test.
