Brief Summary

Determining the predictors that are effective on work performance and preventive approaches to be developed for these predictors must be individual and adaptable to every environment, time, and equipment. In this context, the purpose of the present study was to show the relations between neck disability, Upper Trapezius (UT) muscle activation, posture, and demographic characteristics with typing task performance in office employees who have neck pain by using their equipment in their workplaces.

Outcome Measures

Primary Outcomes (5)

• Neck Disability Index (NDI)

  The NDI is a self-reported scale consists of pain intensity, personal care, lifting, reading, headache, concentration, work, driving, sleeping and leisure time activities sections. The total score varies between 0-50 and the increase in total score indicates the increase in the severity of the neck disability: "0-4 no disability, 5-14 mild disability, 15-24 moderate disability, 25-34 severe disability, and ≥35 complete disability".

  10 minutes

• Maximal Voluntary Isometric Contraction (MVIC)

  It is measured by Surface Electromyography (sEMG) for upper trapezius muscle. 3 maximum contractions were performed for 6 seconds at the manual muscle testing position. The maximum value among 3 repeats was recorded as Maximal Voluntary Isometric Contraction (MVIC) (mV).

  10 minutes

• Muscle Activation of Upper Trapezius

  It is the measurement of the Electromyographic activity of trapezius muscles during typing task. According to The Surface ElectroMyoGraphy for the Non-Invasive Assessment of Muscles Project (SENIAM) recommendations for sensors and sensor placement procedures, sEMG was applied for the upper trapezius muscles while performing the computer task in workplace. The mean values (mV) obtained were normalized according to MVIC. Normalized data (%MVIC) was used in the statistical analysis.

  30 minutes

• Forward Head Posture

  The CROM Deluxe is an assessment instrument that lets to measure sagittal, frontal and horizontal plane movements (flexion / extension, lateral flexion, rotation and forward head posture), while resting and also performing a task or work posture.

  10 minutes

• Rapid Upper Limb Assessment (RULA)

  The RULA Assessment Tool is used to evaluate the ergonomic risk factors associated with neck, trunk, and upper extremity musculoskeletal disorders (MSD). The RULA considers biomechanical and postural load requirements of job demands. Scores between 1-7 are classified from "acceptable posture" (no action required) to "very high risk" (implement change now).
