The Journal of the International Society for Prosthetics and Orthotics Prosthetics and International December 1977, Vol. 1, No. 3 Facts to keep in mind when selecting a Modular System To be completely acceptable, a Modular System must be capable of accurate alignment in both frontal and sagittal planes. This is why our connection modules provide for positive positioning in these two planes. Further, a Modular System should provide for quick and easy interchange of foot and knee units without losing the previously determined alignment. Our system of set screws placed at 90° to each other make such interchanges simple yet accurate Only OTTO BOCK connection modules with our feet and knees provide the features described above. And, only the OTTO BOCK ORTHOPÄDISCHE INDUSTRIE KG Modular System offers the variety of foot, knee and hio joints for 3428DUOERSTADT W-GERMANY true versatility in patient fitting.

Chadderton Canada Secretary Aase Larsson Denmark Prosthetics and Orthotics International, 1977,1,133-134 Editorial The President We must all congratulate the United States National Member Society on their performance in hosting our Second World Assembly and Congress. Despite a difficult financial climate and the distances involved for most of our membership many made obvious sacrifices to come and learn, some to contribute and all to renew friendships and exchange experiences. The scientific programme was comprehensive and of high quality. The instructional courses were very well attended and much appreciated; they have clearly come to stay. Congratulations to Anthony Staros, Sidney Fishman, Howard Thranhardt and their hard working colleagues ! The dust has settled and we must now rouse ourselves from the inevitable let down which follows great events. We constitute a Society which exists not only to meet every three years. We have clear objectives embodied in our constitution and reflected in our Society's structure. Our broad purpose is to help the disabled of the world and the disabled will not be too impressed by their vision of a thousand-odd people cavorting and disporting themselves in the fleshpots of New York, however well they have been successful in informing each other to the patient's ultimate benefit. What will engage their interest will be hard news such as the foundation of a new Technical Committee of the Inter national Standards Organization which will ensure proper standards for the equipment their disability demands. In our efforts we must seek to drive towards an end product either in the form of publication of the useful information or towards methods of operation and collaboration which will ensure direct benefits for our patients. These efforts must reflect needs and priorities and in prosecuting them we should be sensitive to the responsibilities of the United Nations and the World Health Organization and work hand in hand with them in their endeavours. The contributions to our meeting in New York by Bradford Morse and Ms. Sipila are significant pointers to the way we must go and the pitfalls we must avoid. You, the members, have responsibilities not only to your National Member Societies but also to the international field by the very fact of your membership. Nevertheless you will be more effective by operating through your National Member Society; fostering the objectives of our Society, stimulating your membership to hold scientific meetings and instructional courses, contributing your ideas, offering to help in international projects and persuading your colleagues to similar efforts. You can, for example, help in a simple and practical way by persuading university, college and hospital libraries to subscribe to "Prosthetics and Orthotics International". Descriptions of your activities, problems and aspirations reported to the Secretariat regularly can be of enormous benefit to the Executive Board in making decisions, promoting activities and in guiding the Society. If you have an idea or problem which seems to be directly within the responsibility of a particular standing committee, write direct to the relevant chairman and send a copy to the Secretariat. The Standing Committees are presently planning their programme of work and we hope to make appropriate statements of projects in the next number of this Journal. Suggestions and critiques either before or after their plans are announced will be welcome. Two of the new Standing Committees will be meeting shortly. First the Protocol Committee will be discussing the operation of the Society and recommending to the Executive Board guidelines on which they can base their work. It will have a continuing responsibility and will encompass such matters as constitutional interpretation and reform. Your observations, comments and suggestions will be given serious consideration by the Committee. The second of these Committees—the Conference Committee—has a responsibility to create a protocol for the conduct of all ISPO Conferences. The protocol they will recommend to the Executive Board will lay down requirements for the conduct of our triennial Congresses and offer guidance to those responsible for regional and national conferences. As a standing committee the members will individually and collectively always be available for advice and help. 133 134 Editorial Our next general assembly and congress will be held in the Netherlands subject to satisfactory arrangements being made. Our Dutch friends will have a major task on their hands in preparing for what we believe will be bigger and better than our previous efforts. AH members should give them support by making as firm a committment as they can to come to Holland in 1980. We should all now prepare by organizing our work studies and researches so that we can make useful contributions to the Congress. We will certainly expect many contributions on clinical, technical and scientific subjects of importance but it would be extremely valuable if national member societies were to make epidemiological studies of the various disability categories in their respective countries and regions. National statistics are not always reliable and even small studies, if meticulously conducted, will test the validity of existing
