简要总结
In this study; aimed to determine an individual-centered, effective physiotherapy method to reduce the negative impacts of the forward head posture on work-related functions and to increase body awareness and functionality among office workers. In addition, aimed to reduce the loss of work with measures to improve the quality and efficiency of work.
详细描述
The purpose of this study is to determine the effects of preventive physiotherapy practices on work related musculoskeletal disorders in office workers.
With this purpose, in this study; aimed to achieve improvement on forward head posture, upper extremity functions and cervical pain reduction through three interventions (supervised EMG biofeedback exercise training, home-based exercise program and posture training/ergonomic regulations). Work related changes in muscle activation of Upper Trapezius and posture will be evaluated while working on a computer task in actual work environment. Differences in posture and muscle activation between computer task and resting position, will be determined before and after the intervention.

结局指标
主要结局
Maximal Voluntary Isometric Contraction (MVIC)
时间窗: 10 minutes
It is assessed by Surface Electromyography (sEMG) for upper trapezius muscle. 3 maximum contractions are performed for 6 seconds at the manual muscle testing position. The maximum value among 3 repeats is recorded as Maximal Voluntary Isometric Contraction (MVIC) (mV).
Muscle Activation of Upper Trapezius
时间窗: 30 minutes
It is the measurement of the Electromyographic activity of trapezius muscles during functional tasks and rest. According to The Surface ElectroMyoGraphy for the Non-Invasive Assessment of Muscles Project (SENIAM) recommendations for sensors and sensor placement procedures, sEMG will be applied for the upper trapezius muscles while resting and also performing the computer task in workplace. The mean values (mV) obtained are normalized according to MVIC. Normalized data (%MVIC) are used in the statistical analysis.
Cervical Range of Motion (CROM) / Forward Head Posture
时间窗: 10 minutes
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.
次要结局
- Constant-Murley Score (CMS)(10 minutes)
- The Disabilities of the Arm, Shoulder and Hand Score Work Module (DASH-W)(2 minutes)
- Rapid Upper Limb Assessment (RULA)(10 minutes)
- The Disabilities of the Arm, Shoulder and Hand Score (DASH)(10 minutes)
- Neck Disability Index (NDI)(10 minutes)
- Neck Pain and Disability Scale (NPAD)(10 minutes)
