Background: Detection of abnormal movement patterns and disorders and their classification into specific sub-categories may result in effective therapeutic choices. Classification of movement system impairments has provided seven sub-categories for movement disorders in the knee joint with specific treatment recommendations for each.
Objectives: This study aimed to investigate the effectiveness of specific treatments proposed by this classification method and compare the effectiveness of this treatment method with routine ones.
Methods: Participants who met the inclusion criterion were randomly assigned into control and experimental groups after the diagnosis of their movement impairment. Subcategories including patellar lateral glide syndrome and tibiofemoral rotation syndrome were recruited. Experimental groups were treated specifically based on their impairment; however, all control groups received the same routine physiotherapy, regardless of their movement impairment. Two knee function and disability instruments were used, including Knee Injury and Osteoarthritis Outcome Score and the Lower Extremity Functional Scale. Eventually, each experimental groups outcome scores on the visual analog scale and frontal plane projection angles were compared with those in the control group.
Results: Movement system impairments could be one of the contributing factors for disabilities in people with knee pain. Treatment based on the classification of these movement impairments would lead to better outcome.
Conclusion: We assumed that the specific treatments based on the movement impairment classification have beneficiary over the routine treatment. This would also give clues about the validity of this classification in knee pain. If this is the case, detecting the movement impairment and giving treatment on this basis could be used as a comprehensive guideline.
