The need for documentation and evaluation of phystiotherapy treatment is great. The aim of this study was to develop an instrument for registration of the measures and amount of time used for individual patient treatment. This instrument was developed at the department of Geriatric rehabilitation, Umeå University Hospital, Sweden. It consists of record for registration of the measures and the amount of time used as a manual and was developed and evaluated in several steps by nine physiotherapists. This version of the instrument was then tested for inter-rate reliability. The method used to develop the instrument ensures good validity. The inter-rater reliability of the instrumentas for the registred measurs and the amount of time is high (Cohen´s kappa 0.64-1.0 and Pearson´s correlations coefficient 0.96). Therefore we conclude that this instrument is useful to physiotherapy for documentation in clinical practise, quality control and rehabilitation research.
