Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Pain-free grip strength: the mean value (kg) of three efforts presented as a ratio of the maximum grip strength of the unaffected side will be included A Jamar hand dynamometer is used. Measured at baseline, 6 and 12 weeks follow-up 2. Pain and functional disability measured using the patient-rated tennis elbow (PRTEE) questionnaire at baseline, 6 weeks and 12 weeks follow-up. 3. Pain measured using the visual analogue score (NRPS) at baseline, 6 and 12 weeks | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Tendon thickness, neovascularity, presence of spurs, calcification and/or tears in the common extensor tendon (lateral epicondyle) measured using diagnostic ultrasound imaging at baseline, 6 and 12 weeks follow-up 2. Isometric strength of elbow flexors and extensors measured using Bio Fet force evaluation system (mean of three efforts of the maximum isometric contraction) at baseline, 6 and 12 weeks follow-up 3. Self-perceived recovery measured using 6-point Global Rating Of Change (GROC) scale at 6 and 12 weeks follow-up | — |
