Fifty-three patients diagnosed as having one of several types of extensor mechanism disorders of the knee were randomly assigned to one of four treatment groups to assess the effects of one of four different modalities (ice, phonophoresis, iontophoresis, and ultrasound/ice contrast). Following four physical therapy treatments over a 10-day period, the group treated with the ultrasound/ice contrast demonstrated the greatest subjective improvement (47%). The pre- to post-treatment isometric strength resulted in a 28% improvement in knee extension strength and a 34% improvement in knee flexion strength. The authors emphasize that evaluation should include assessment of quadriceps tone and strength as well as careful palpation to determine the irritable structures. Ultrasound/ice is advocated as the most effective choice of the modalities tested for treatment of pain associated with extensor mechanism disorders. J Orthop Sports Phys Ther 1986;8(5):255-259.
53 名被诊断为患有多种膝关节伸肌机制疾病的患者被随机分配到四个治疗组中的一个，以评估四种不同方式（冰敷、声透、离子电渗和超声/冰敷对比）之一的效果。在 10 天内接受了 4 次物理治疗后，接受超声/冰敷对比治疗的组显示出最大的主观改善（47%）。等长力量的治疗前到治疗后，膝关节伸展力量提高了 28%，膝关节弯曲力量提高了 34%。作者强调，评估应包括评估股四头肌的音调和力量，以及仔细触诊以确定易激惹的结构。超声/冰敷被提倡为治疗与伸肌机制疾病相关的疼痛的测试方式中最有效的选择。J Orthop Sports Phys Ther 1986;8(5):255-259.
