Effect of Instrument-Assisted Soft Tissue Mobilization on Muscular Activity during Walking and Sit to Stand Task in Individuals with Knee Osteoarthritis

Investigate the effect of Instrument Assisted Soft Tissue Mobilization on function, quality of life and activity of muscles around the knee joint at different preferential and high walking speeds and sit to stand task in people with knee osteoarthritis

Clinical trial with control group, double-blind, randomized by block design, on 34 patients

The location of this intervention will be in the research therapeutic center of movement disorders, Department of physiotherapy, Tarbiat Modares University. After an introductory session, people will enter the intervention phase. Individuals will be randomly assigned to the treatment and placebo groups. Participants and outcome assessors are unaware of the allocation of study groups. The intervention will be performed in four sessions over two weeks

Inclusion criteria: Women and men with knee osteoarthritis, a positive Clark test, and two and three degrees of osteoarthritis, according to the kellgren Lawrence scale؛ Exclusion criteria: Having a history of hip or knee joint fracture or ligament injury on the affected side that resulted in permanent injury

In the intervention group, soft tissue mobilization will be performed with the instrument, but the control group will receive the instrument as a placebo. Both groups will do strengthening and stretching exercises. The intervention will be performed for both groups in four sessions over two weeks.

Updating to provide accurate and up-to-date information about the study

Individuals are admitted to the study depending on criteria for inclusion and exclusion. The stratified block randomization approach will be used for this study's randomization. People with moderate osteoarthritis are classified into two subgroups based on the amount of pain (three and four) or (five and six). In each subgroup, randomization is performed by four blocks (two in the treatment group and two in the placebo group). For random allocation, code 1 for treatment and code 0 for placebo are placed in sealed envelopes. In this way, the people of each subgroup take one of the sealed envelope and are assigned in the treatment or placebo group according to the code.

Participants will be randomly divided into two groups of treatment and placebo. In the treatment group, the master therapist uses soft tools to treat soft tissue by selecting pressure, direction, type of stroke, distance, duration, speed and type of tool. But in the placebo group, the use of the tool is dramatic and has no therapeutic properties. Both groups receive the same strengthening and stretching exercises so people do not notice this difference. The evaluator is also blind.

Information about the main outcome can be shared after people are not identified
