Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Outpatients participated in either a telerehabilitation once a week for a period of six weeks. The telerehabilitation program involved participants receiving their rehabilitation program via a videoconference established across an internet link using a custom built telerehabilitation system. As no physical contact between therapist and patient was possible across the link, the rehabilitation program consisted of self-applied techniques under the supervision of the remote therapist and a customised exercise program to adress the participants specific rehabilitation needs.

Outpatients participated in a traditional face-to-face therapy program once a week for a period of six weeks. Face-to-face therapy consisted of tradational one-on-one rehabilitation in the hospital outpatients department.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Sealed Envelope
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomized code: Fixed block size with stratification to intervention therapist
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
A therapist with no other involvement in the study and who was blinded to the method of intervention performed all pre- and post-intervention patient outcome measures. Due to the nature of the interventions, neither subject nor treating therapist blinding was possible.
