Abstract
Background: Osteoarthritis (OA) of the knee is a degenerative disorder that affects the joint which causes pain, stiffness, swelling, muscle weakness, and functional impairments. Proprioception in the OA knee seems to be impaired when compared with the normal counterparts. Manual therapy is one of the hands-on therapies delivered by physiotherapists. However, there is not much information on how manual therapy affects joint proprioception, although some studies show a positive response. Mulligan’s mobilization technique is common for spinal and peripheral joints to correct positional faults.
 Aim: To systematically identify and to evaluate the effects of mulligan mobilization on the proprioception of the OA knee.
 Methods: Various electronic databases like PubMed Central, Medline, Google Scholar, ProQuest and CINAHL are searched from 2001 to 2021. Multiple search criteria were used in the search of relevant articles based on the selection criteria used. Four articles that fit the criteria were taken based on the PEDro Scores of above 5. The two specialists analysed all the papers. The articles which cover mulligan’s mobilization and proprioception of the knee were only selected.
 Results: Four articles that fit the criteria were reviewed which demonstrated baseline comparability and reported point estimates and measures of variability.
 Conclusion: This systematic review has concluded that the knee joint proprioception was improved with applying the Mulligan’s manual therapy, whereas the neurophysiological activity is not well understood.
Highlights
Osteoarthritis (OA) is one of the articular disorders in adults over 60 years [1]
World health organization (WHO) has stated that about 9.6% of men and 18.0% of women above 60 years worldwide have symptomatic osteoarthritis. 80% have the limitation of movements in the joints, and 25% have difficulty performing major daily activities [3]. 22% - 39% of individuals have OA above 60 years [2]
Studies have identified that knee joint is more prevalent in OA compared with other OA joints; it was found that more than 37% above 60 years have OA Knee [4]
Summary
Osteoarthritis (OA) is one of the articular disorders in adults over 60 years [1]. It is likely to increase as the age grows. It is the most prevailing condition which causes disability in the elderly population [2]. Studies have identified that knee joint is more prevalent in OA compared with other OA joints; it was found that more than 37% above 60 years have OA Knee [4]. Pain in the OA knee may not be related to the radiographic changes. Osteoarthritis (OA) of the knee is a degenerative disorder that affects the joint which causes pain, stiffness, swelling, muscle weakness, and functional impairments. There is not much information on how manual therapy affects joint proprioception, some studies show a positive response.
