One-year follow-up of a randomised controlled trial on added splinting to eccentric exercises in chronic midportion Achilles tendinopathy.

OBJECTIVE The study examined whether the addition of a night splint to eccentric exercises is beneficial for functional outcome in chronic midportion Achilles tendinopathy. DESIGN One-year follow-up of a randomised controlled single blinded clinical trial. SETTING Sports medicine department in a general hospital. PATIENTS 58 patients (70 tendons) were included. INTERVENTIONS All patients completed a 12-week heavy load eccentric training programme. One group received a night splint in addition to eccentric exercises. MAIN OUTCOME MEASUREMENTS Outcome scores were: Victorian Institute of Sport Assessment-Achilles (VISAA) score, subjective patient satisfaction and neovascularisation score measured with power Doppler ultrasonography (PDU). RESULTS For both groups the VISA-A score increased significantly (from 50 to 76 (p<0.01) in the eccentric group and from 49 to 78 (p<0.01) in the night splint group). No significant differences in the VISA-A score were found between the groups from baseline to one year (p = 0.32). The presence of neovessels at baseline did not predict a change in the VISA-A score after one year in the whole group (p = 0.71). CONCLUSION Eccentric exercises with or without a night splint improved functional outcome at one year follow-up. At follow-up there was no significant difference in clinical outcome when a night splint was used in addition to an eccentric exercise programme. Between 3 months and one year follow-up, a continuing increase in the VISA-A score was found. Assessment of the neovascularisation score with PDU at baseline has no prognostic value on long-term clinical outcome.
