Translation, cross-cultural adaptation and reliability of the International Knee Documentation Committee (IKDC) subjective knee form and the tampa scale for kinesiophobia (TSK) into Hebrew.

INTRODUCTION: The International Knee Documentation Committee-Subjective Form (IKDC-SF) is one of the most used measures for evaluating the quality of life among people experiencing knee pain but is not yet available in Hebrew. Similarly, the Tampa Scale for Kinesiophobia (TSK), used to evaluate fear of movement, is not available in Hebrew. This study aimed to determine the reliability and construct validity of the Hebrew IKDC-SF and TSK among people experiencing chronic knee pain. MATERIALS AND METHODS: Translation and cultural adaptation of the IKDC-SF and TSK questionnaires, followed by test-retest reliability within a two-week interval. We report on internal consistency, construct validity, and the psychometric properties of both questionnaires. RESULTS: Both questionnaires showed high internal consistency (Cronbach's α = 0.85 and 0.89, respectively) and test-retest reliability, expressed by the Intra-Class Correlation Coefficient (ICC = 0.89 and 0.80 respectively). The standard error of measurement, group smallest real difference and minimal detectable change for the IKDC-SF were 4.66, 9.13, and 12.91 points, and 3.64, 7.13, and 10.08 points for the TSK, respectively. CONCLUSION: We demonstrated that the Hebrew version of the IKDC-SF and TSK is reliable and valid for assessing QoL, function, and kinesiophobia among people experiencing chronic knee pain.

The prevalence of myofascial trigger points in hip and thigh areas in anterior knee pain patients.

BACKGROUND: Anterior knee pain (AKP) is a widespread problem among young athletes and soldiers. There are many theories on the etiology of AKP but there is little reference to myofascial trigger points (MTrPs) as a possible contributor. AIM: To evaluate the association between AKP and prevalence of active and latent MTrPs in the hip and thigh muscles in soldiers. METHODS: A cross-sectional study was conducted in the Beer-Sheva military outpatient physical therapy clinic. Subjects were 42 men and 23 women referred for physical therapy, 33 with a diagnosis of AKP (cases) and 32 with upper limb complaints (without AKP, controls). All subjects underwent physical evaluation by an examiner blinded to their identity and medical condition. The following muscles were assessed bilaterally for active or latent MTrPs: rectus femoris (proximal), vastus medialis (middle and distal), vastus lateralis (middle and distal) and gluteus medius (anterior, posterior and distal). RESULTS: In six out of eight areas, the cases had a higher prevalence of total active and latent MTrPs than the controls. When summarizing MTrPs by muscle, cases had significantly more MTrPs than controls in each muscle. The largest difference was found in vastus medialis and vastus lateralis; nearly half of the cases had MTrPs in these muscles. CONCLUSIONS: Subjects with AKP have a greater prevalence of MTrPs in their hip and thigh muscles than controls, indicating an association between MTrPs and AKP. Further research is necessary to determine whether MTrPs are the cause or the consequence of AKP.
