The effect of eight- weeks of body balance exercises on posture control, balance, lower limb muscle strength and proprioception of knee and ankle joints in elderly women with knee osteoarthritis

Determining the effect of eight weeks of air balance exercises on the variables of posture control, balance, muscle strength of the lower limbs and proprioception of the knee and ankle joints in elderly women with knee osteoarthritis.

Clinical trial with control group, with parallel group, single blinded, randomized

The tests will be carried out by the specialists at the Sport Rehabilitation Laboratory, and then interventions and exercises will take place in the gym. And participants will be randomly assigned to intervention and control groups based on allocation concealment using the SNOSE method. This study will be conducted in a blind way so that the outcome assessors will not know about the allocation of the study groups and the reason for their presence in this study.

Inclusion criteria included elderly women with knee osteoarthritis, not having any history of knee, no injection of intra-articular steroid in the last six months, having pain in the last three months, and non-entry criteria: In regular exercise activities during the research, cardio-respiratory disorders and neurological diseases, History of fracture or surgery of lower limb joints.

The intervention group will be received body balance exercises that include breathing, stretching, balance and strength exercises for 8 weeks and 3 sessions of one-hour each week. To do the exercises, tools will be used that help the mobility of soft tissue. Control group without intervention

posture control, balance, muscle strength and proprioception of knee joint

Randomization is based on the Random Number Generator software version 1.1 and uses the SNOSE method to assign double groups based on allocation concealment. The randomization of subjects was done in two stages. First, each of the subjects chooses a number between 1-30 using a lottery, then fifteen random numbers are selected between the numbers 1-30 using the Random number generator software, and according to the generated numbers, the chosen numbers of subjects are divided into two groups. Random Number Generator is a simple software for generating random numbers between two specified numbers. To use this software, it is enough to determine the smallest and largest number as well as the wanted number of random numbers and click on the Generate integer button to generate random numbers corresponding to the number and in the specified interval. The software can be downloaded from the following site: http://fa.softoware.org/apps/get-random-number-generator-66296-for-windows.html. To allocation concealment, the closed-sequence envelope method with random allocation (SNOSE) will be used. An accident is recorded on a card and the cards are placed inside the named cleaners in order. In order to maintain random randomness, the numbering on the external surface is done in the same way. Finally, the lids of the letter envelopes are pasted and placed inside the boxes, respectively. At the beginning of the registration of the participants, according to the order of the participants and the conditions of the study, one of them is a special test book or letter.

In the study, the outcome valuators (laboratory technicians) will be asked to take the desired tests from the participants. These people will be unaware of the purpose of the research, the allocation of study group, and the reason for their presence in the laboratory, and they only evaluate the variables and record their observations.
