Group therapy involves treating a small group of patients with common disabilities together. The group setting provides opportunities to build endurance, increase performance speed, and gain confidence through encouragement from therapists and peers. Exercises are taught simultaneously but performed individually according to each patient's capacity with assistance from therapists. Advantages include learning responsibility, working with others, gaining treatment confidence and motivation from competition. The group approach also helps patients temporarily forget disabilities through games and objectives while saving therapists' time. Disadvantages can arise from faulty patient selection, inadequate explanations, overcrowding or poor therapist technique.
