Summary

An aging society is known as having at least 7% of its population aged 65 and older, whereas 14% or more known to be an aged nation. Age has a detrimental effect on the physical performance and the muscle strength, the reduced muscle strength, mass and structure in the elderly are due to aging, disuse and inactivity. In the elderly, the reduction of muscle strength is faster than the associated loss of muscle mass. The maximum isometric strength of knee extensors and muscle mass decrease due to aging. The combination of quadriceps and handgrip strength weakness in the elderly is associated with the poorest scores on quality of life, GP contact-time, gait speed, hospitalization and disability in daily living. Quadriceps weakness among elderly is also proved to be a contributing factor to fall among frail nursing home residents. A systematic review and meta-analysis revealed that quadriceps muscle weakness was associated with greater risk of developing knee osteoarthritis during 2.5 to 14 year follow-up in either gender. In overall, aging cause reduce muscle strength, especially quadriceps muscle, can cause many others negative consequences, thus a study of effect motor imagery on quadriceps muscle strength in community-dwelling elderly should be carried out, if this study is proven to effectively, motor imagery technique can be widely utilized on bedridden elderly or elderly who have severe cardiovascular disease who unable to perform physical activity to maintain or improve their muscle strength.

Description

The decrease in the number of skeletal muscle and decline in muscle function is the most important factor in influencing the ability to perform physical function independently in the later stage of our life. The reduction of quadriceps strength with advancing age in both gender is proved to be associated with an increased risk of fractures, increased chance of worsening of knee pain, high risk of osteoarthritis. Quadriceps weakness is also proved to be a contributing factor to falls among frail nursing home residents.

Motor imagery had been widely utilized and proved to benefits different population. Motor imagery training makes a better motor performance as proved to be an effective tool in stroke rehabilitation, it is effective and useful when there are severely injured patients. This imagery training has turned into performance enrichment ways and simulation tools which has been widely utilized in sports psychological interventions as well.

Motor imagery can be defined as a dynamic mental state during which the representation of a given motor act or movement is rehearsed in working memory without any overt motor output. Motor imagery can also be defined as utilizing whole senses to reform or form an experience in one's thought. Motor imagery can be performed in different modes which can be classified into visual, tactile, auditory, gustatory, olfactory, and kinesthetic modes. There are lot of studies which have showed that motor imagery task does activate the cortical and subcortical regions of the brain and they overlap in a great extent with task required movement execution. The parts of the brain proved to participate in motor control consists of the premotor cortex (PMC), supplementary motor area (SMA), as well as the primary motor cortex (M1). All these brain areas are nearly related to the basal ganglia and cerebellum, as a result, large feedback loop systems are formed. The aim of this research is to investigate the effect of motor imagery training on quadriceps strength among community-dwelling elderly. The second aim of our study is to compare the gender differences with regards to quadriceps muscle improvement after motor imagery training.
