The Effects of Isokinetic Exercises on Muscle Strength, Joint Position Sense, and Kinesiophobia in Patients With Multiple Sclerosis: a Randomized Controlled Trial

Visual Analog Scale

时间窗: At baseline (10 minutes before the start of the treatment) and 8 weeks after start of the treatment

Pain intensity was evaluated with the Visual Analog Scale. Using a ruler, a 10 cm line was drawn which provided a range of scores from 0-100. Than the patients marked the point that showed their pain intensity on this line. A higher score in Visual Analog Scale indicates greater pain intensity.

Tampa Scale of Kinesiophobia

时间窗: At baseline (10 minutes before the start of the treatment) and 8 weeks after start of the treatment

Kinesiophobia which is described as fear of movement and physical activity was evaluated using the Tampa Scale of Kinesiophobia, which is a 17-item self-report survey. The range of scores are from 17 to 68 where the higher scores indicate an increasing degree of kinesiophobia. If the total score was above 37 points, the patient was considered to have a high level of kinesiophobia.

Multiple Sclerosis Quality of Life-54 Total Score, Physical and Emotional Composite Scores, and Pain Subscale Score

时间窗: At baseline (10 minutes before the start of the treatment) and 8 weeks after start of the treatment

This is a multidimensional health-related quality of life measure that combines both generic and multiple sclerosis-specific symptoms in a single instrument. The 54 items are divided into 12 multi-item and 2 single-item scales.Health distress, overall quality of life, emotional well-being, role limitations-emotional and cognitive funtion items' final scores averaged and mental composite score was calculated. Physical function, health perceptions, energy/fatigue, role limitations-physical, pain, sexual function, social function, health distress items' final scores were averaged and physical composite score was obtained.Total score was obtained by averaging the mental and physical composite scores.Final scores can be between 0-100 points for total, mental, physical and pain scores. Higher values indicate better quality of life for total, physical and mental scores and worser pain levels for pain score.

Isokinetic Muscle Strength Test of the More and Less Affected Knees

时间窗: At baseline (10 minutes before the start of the treatment) and 8 weeks after start of the treatment

The peak torque/body mass index of the quadriceps and hamstring muscles at 60°/s and 180°/s velocities were measured by an isokinetic dynamometer (Biodex Multijoint Pro 3) in Newton/meter. A definite muscle strength value has not been defined. Literally, healthy controls and patients are compared. Higher scores indicate better muscle strength.

Joint Position Sense of the More and Less Affected Knees

时间窗: At baseline (10 minutes before the start of the treatment) and 8 weeks after start of the treatment

Absolute angular errors of the 15°, 45°, and 60° and the mean absolute angular error of the more and less affected knees were measured by an isokinetic dynamometer (Biodex Multijoint Pro 3) with active-active angular reproduction method. Estimating the target angel procedure was repeated at 45°, 15°, and 60° and for both the more and less affected legs. After the joint position sense testing, three angles estimated by the patients were averaged, and the angular error was calculated for each target angle. Absolute angular error was calculated by averaging the angular errors, regardless of the numbers being negative or positive. The absolute angular error values of the three target angles were averaged to obtain the mean absolute angular errors. A definite angular error value has not been defined. Literally, healthy controls and patients are compared. Higher scores indicate worser joint position sense.
