LW5/7 is a standing para-alpine and para-Nordic skiing classification for skiers with upper extremity issues in both limbs that may include double amputation of both arms and hands or dysmelia of the upper limbs. The class has three subclasses defined by the location of the disability on the upper extremities. International classification is done by IPC Alpine Skiing and IPC Nordic Skiing. On the national level, classification is handled by national sports federation such as Cross-Country Canada.
Skiers in this class use two skis and no ski poles in para-alpine and para-Nordic, though skiers can use mini-ski poles provided they cannot hold a ski pole without the use of a prosthesis. Skiers develop techniques to ski that compensate for balance issues as a result of missing arms. A factoring system is used in para-alpine and para-Nordic to allow LW5/7 skiers to compete fairly against other skiers with disabilities. While this classification was not grouped with others at the 1984 Winter Olympics Exhibition Competition, it was grouped with other standing classes during events in the 1990s and 2000s.
