การฝึกพัฒนาผู้สูงอายุที่ใช้wheelchair

INTRODUCTION Thailand has an increasing population of the country every year. The National Economic and Social Development Board predicts that in 2021 Thailand will approach to the complete aging society, which is 20% of the population aged 60 years and 2036 will reach to the super senior society, which will increase to 30% and tend to increase.   Effect from seated leg press exercise on knee extensor strength in elderly said that people aged 50-60 years, every 15 years, there will be a 15 percent reduction in muscle and bone mass.

INTRODUCTION Exercise is health’s essential in elderly for  the deterioration and increase the strength of various organs of the body. Research has shown that if the elderly do not have movement or daily activities or patient who has to take a wheelchair in Long time. They will affect in joint pain when moving any position for a long time.   Therefore, the elderly need exercise to maintain the Joint Mobility by stretching the muscles and moving the joints to the fullest regularly. Team research to consider that Increasing physical activity of the elderly is important. And also, that patients with wheelchairs lack a lot of physical activity in the lower limb. when considering the lower limb exercise wheelchairs for the elderly, it is hardly found in the shop. Most are accessories that can be used with wheelchairs and accessories is not easy to use and requires installation, moving. And also still vulnerable to injuries, So have to put someone under observation and accessories has a very high price.

In order to design and develop of In order to design and exercise wheelchair for lower limb in develop of exercise wheelchair the elderly with a safe structure for lower limb in the elderly, and can also adjust force and angle type of movement motion is of the leg while elderly exercise on Leg Press for elderly. With a wheelchair. safe structure and can use resistance force for exercise PURPOSE

RESEARCH HYPOTHESIS Exercise wheelchair for lower limb in the elderly, can movements as researchers needs and safe.

VARIABLE Independent variable The desired resistance force. Dependent variable The real resistance force. Controlled variable Characteristics of measurement resistance force.  

Expected Benefits & Application The elderly or patient can develop the quality of life and physical fitness, especially the lower limb muscle with self-exercise in safe and comfortable environment. Also lighten the physical therapist and sport scientist burdens. And decrease inaccessible and expensive imported equipment and medical devices in hospital or public health center. Including decreasing resources about health care for elderly.

STATISTICS ANALYSIS correlation coefficient is used to analyze validity and reliability of the force in each level designed with the force in each level that is actually measured at the level of the wheelchair. SPSS to study the resistance and the angle of the wheelchair

RESEARCH INSTRUMENTS Digital arm scale brand (WeiHeng generation WH -C300)  to measure the resistance of the exercise wheelchair Kinovea programe to the measurement angle of plate on exercise wheelchair. Microsoft Excel program used to collect data to bring the values into the SPSS program to study the resistance and the angle of the wheelchair to exercise.

METHODS The researcher design and development of lower limb strengthening exercise wheelchairs for elderly with leg press exercise. For the elderly who can modify the resistance level to 5 levels. The researcher perform strength testing, modify the intensity leg press exercise of equipment for elderly do not hinder the use of wheelchairs. The similar exercise with leg press exercise. Focus Quadriceps, Hamstrings, Gluteus Maximus, and Calves

METHODS The researcher design of lower limb strengthening exercise wheelchairs for elderly who can modify the resistance level to 5 levels. Increase the intensity of exercise, each levels is not the similar intensity. • Level 1 : 0.5 Kg ( 0.4905 N ) • Level 2 : 1 Kg ( 0.9810 N ) • Level 3 : 1.5 Kg ( 1.4715 N ) • Level 4 : 2 Kg ( 1.9620 N ) • Level 5 : 2.5 Kg ( 2.4525 N ) Causing the exercise of the lower limb muscles is not the similar.

METHODS Measurements resistance To study “Validation” force of leg press 5 level. resistance force of measurement Design and development exercise wheelchair. To study “Reliability” Prepare leg press wheelchair resistance force of measurement Put the Pedal down Prepare leg press wheelchair Put the Pedal down 1 times 2 times Attached the weight scale Let the pedal full back Attached the weight scale Prepare leg press wheelchair Let the pedal full back Put the Pedal down Collect the data form weight scale Collect the data form weight scale Attached the weight scale Validation analysis Let the pedal full back Collect the data form weight scale Reliability analysis Reliability analysis with Reliability analysis Correlation Coefficient. SPSS and Correlation coefficient analysts data validation and reliability.
