Primary study design	Interventional
Study design	Multicentric controlled randomised trial
Secondary study design	Randomised controlled trial
Scientific title
Study objectives	Radiotherapy for painful heel spur with a very low dose (0.6 Gy) is as effective regarding pain relief as a standard radiotherapy with a dose of 6.0 Gy.
Ethics approval(s)	Ethics committee of the Saarland Medical Association, Saarbrücken (Germany), 14/05/2007, ref: 14/07
Health condition(s) or problem(s) studied	Painful heel spur
Intervention	Radiotherapy to the plantar aponeurosis and the calcaneus: 1. Experimental arm: total dose of 0.6 Gy in single fractions of 0.1 Gy twice weekly, total duration three weeks 2. Standard arm: total dose of 6.0 Gy in single fractions of 1.0 Gy twice weekly, total duration three weeks
Intervention type	Other
Primary outcome measure(s)	1. 12-item Short Form health survey (SF-12): summed score, measured three months after the end of radiotherapy 2. Calcaneodynia summed score, measured three months after the end of radiotherapy 3. Visual Analogue Scale (VAS) score, measured three months after the end of radiotherapy
Key secondary outcome measure(s)	1. SF-12: single scores, measured three months after the end of radiotherapy 2. Calcaneodynia single scores, measured three months after the end of radiotherapy 3. Painless time interval after therapy, measured three months after the end of radiotherapy
Completion date	31/05/2009
