Study summary

There are very few studies on the effect of core stabilization exercises on balance, posture and trunk muscle endurance in healthy sedentary individuals in literature. The goal of the study is to investigate the effects of core stabilization exercises on balance, trunk muscle endurance and posture in healthy sedentary individuals. According to the results of International Physical Activity Questionnaire, the researcher includes sedentary individuals over the age of 18 in the study. The participants are divided into two groups as control (n=21) and exercise (n=21) groups. The outcome measures are The Stabilizer Pressure Biofeedback Unit, New York Posture Assesment Scale, Korebalance Balance System, trunk muscle endurance tests. Intervention includes core stabilization exercises 3 times a week and walking twice a week for 6 weeks. There is no treatment or intervention for the control group. The researcher evaluates both groups at the beginning and 6 weeks after the intervention.

Read the detailed description

Core stabilization exercises are performed under the supervision of a physiotherapist as face-to-face exercises, guided online exercises, and as an individual home exercise each once a week, totaling 3 times a week. Each exercise will be performed with 10 repetitions for 8 seconds. Each of the exercises is varied from easy to difficult. Progress in the exercises will be achieved by increasing the difficulty level of the exercises according to the condition of the participant once every two weeks.

Study arms

  • Experimental
    Exercise Group

    Intervention includes core stabilization exercises for 45 minutes 3 times a week. Participants do exercise face to face under supervision of a physiotherapist and via an online application under the supervision of a physiotherapist once a week. Also participants do home exercise once a week. Exercise group walk for an hour in other two days.

    Other: Core Stabilization Exercises

  • No intervention
    Control Group

    There is no exercise or intervention for control group.

Interventions

  • OtherCore Stabilization Exercises

    Core stabilization exercises are known as a very effective exercise method based on the motor learning principle, performed with the individual's own body weight to strengthen the muscles, improve balance, posture, trunk muscle endurance and flexibility.Each exercise was performed for 7-8 seconds with 10 repetitions. Progression in the exercises was achieved by increasing the difficulty level of the exercises according to the participant's condition once every two weeks.

What researchers measure

Primary outcomes

  1. New York Posture Assessment Scale

    This test assesses alignment of various body parts of an individual in anatomical position. The New York Posture Rating Scale detects postural changes. There are 3 figure drawings for each of the 13 different body parts that provide general postural alignment. In the evaluation, five (5) points are given if the person's posture is correct, three (3) points if moderately impaired, and one (1) point if severely impaired. At the end of the evaluation, the total maximum score is 65 and the minimum is 13. Postural disturbances increase as the score decreases.

    Time frame: 6 weeks

  2. KoreBalance Balance System

    The Korebalance Balance System is a computerized balance and exercise system. The software of the system assigns a score following static and dynamic balance evaluations. As stated in the device manual, a score of 700 and below was considered normal and above was considered risky for static balance and a score of 2000 and below was considered normal and above was considered risky for dynamic tests. A higher score is associated with more balance disorders.

    Time frame: 6 weeks

  3. Trunk Muscle Endurance Tests

    The endurance of the trunk flexor, trunk extensor and lateral flexor muscles is evaluated by recording the maximum time that the person can maintain the test position. Measurements are made using a stopwatch and the result is recorded in seconds. The tests are repeated twice to save the best measurement value. Tests are terminated when the participant's position deteriorates or when the participant says cannot continue the test.

    Time frame: 6 weeks

  4. International Physical Activity Questionnaire

    This survey lists activities and requests estimates of duration and frequency for each activity performed in the past week. The times are multiplied by the known Metabolic Equivalents (METs) per activity and the results for all items are summed, resulting in the overall physical activity score.

    Time frame: Before Intervention (First Assesment)

Secondary outcomes

  1. The Stabilizer Pressure Biofeedback Unite

    This device evaluates contraction of deep abdominal muscles, muscle activity and segmental stability. The device has values between 0 mmHg and 200 mmHg, varying in intervals of 2 mmHg. Movement or change in position causes volume changes in the pressure bag.

    Time frame: 6 weeks
