About

The purpose of this study is to determine whether the effects of chair massage and/or chair massage with stretching may reduce musculoskeletal pain and discomfort related symptoms associated with the job duties of a cardiac sonographer.

Full description

Staff performing echocardiography exams work in a physically demanding environment. The physical and psychosocial demands of the work environment place a significant amount of stress on the physical well being of the employee. The nature of the work involved includes repetitive movements and static holds while applying intense pressure. These compounded by a challenging ergonomic work environment, often leads to physical tension, pain, and fatigue. Staff and patient characteristics, in particular obesity, present greater ergonomic challenges. In this setting, optimal ergonomics can be difficult to achieve. Repetitive actions in an ergonomically challenging environment can have an accumulative effect that can lead to injury.

Massage therapy has been noted to decrease levels of anxiety and fatigue which is essential to maintaining efficient care in a dynamic environment. Repetitive use, typically leads to shortened, tight muscles that fatigue over time. Once the massage therapy has released the connective tissue tension and restored muscle imbalances, exercise focused on core, trunk strength and those muscles which oppose the repetitively used muscles can further assist the therapeutic benefits of massage.

The cardiac sonographer is usually sitting and reaching forward or to the side, and the musculoskeletal imbalances show up primarily superior to the hips. Massage Therapy research for alleviating musculoskeletal symptoms has been with the use of table massage whereas chair massage research has focused on gaining physiological benefits. Chair massage therapy impacts the head, back, neck shoulders, arms and hands so does impact the areas of musculoskeletal imbalance of the cardiac sonographer. In addition, a massage chair is easy to set up, does not need a great deal of space, and can be provided in semi-private area, as the participant remains clothed. Chair massage literature to date has focused more on physiological responses and albeit positive, not as much on musculoskeletal responses.
