About

The goal of this randomized controlled trial, is to investigate the effect of functional NMES and conventional NMES applied to the lumbar multifidus muscle on body kinematic and kinetic values during the sit-to-stand in individuals with non-specific low back pain. Our study will include 24 participants between the ages of 18-65. Which physiotherapy intervention will be applied to the participants will be determined by the block randomization method, using a table of random numbers. After randomization; NMES to the participants' lumbar multifidus muscle during physiotherapy intervention will be applied in two groups; In the first group, NMES will be applied with the conventional technique during prone position and in the second group, NMES will be applied with the functional technique during the sit-to-stand activity. Evaluations will be made twice for each participant- before and after the intervention. During the evaluation, data regarding the change in body kinetics and kinematics of individuals during the sit-to-stand activity will be recorded with a Vicon camera system. For secondary outcome measures, a visual analog scale will be used to evaluate pain, the Roland Morris Disability Questionnaire and the Oswestry Disability Index will be used to evaluate functional status, and the Tampa Kinesiophobia Scale will be used to evaluate fear-avoidance behavior.

24 participants in 2 patient groups

Functional Neuromuscular Electrical Stimulation Group

Experimental group

Description:

Functional NMES involves stimulating the lumbar multifidus muscle while the individual performs a sit-to-stand activity.

Treatment:

Other: Functional Neuromuscular Electrical Stimulation

Conventional Neuromuscular Electrical Stimulation Group

Experimental group

Description:

Conventional NMES intervention involves only stimulating the lumbar multifidus muscle while the individual is in the prone position, and the individual will not reveal any voluntary contraction during stimulation.

Treatment:

Other: Conventional Neuromuscular Electrical Stimulation
