My mother suffered severely from osteoporosis, being severely bent over for many years before her death at 85. ……….
How tall were you at your tallest? Five foot six inches, I replied. Mmm. Five foot four inches now. Normal, he said. What?????
Yes it is normal to lose two inches of height without necessarily having osteoporosis. The Baltimore Longitudinal Study of Aging found that the cumulative height loss from age 30 to 70 years averaged about 3 cm (1.18 inches) for men and 5 cm (1.97 inches) for women (Sorkin, Muller, & Andres, 1999)……….
- The first step is to set the height of your sewing chair. The seat should be at a height that allows your feet to rest flat on the floor and your knees to make a perfect 90-degree angle. A secretarial chair makes a good, adjustable sewing chair.
- The next step is to lower your sewing machine table until, with your elbows bent at a perfect 90-degree angle, your fingertips can rest on the feed dog of your machine. I am 5 feet 6 inches tall, and my sewing machine table is 22 inches off of the floor.
- Proper chair and sewing machine height, combined with good posture of your back and neck, and hourly breaks, will go a long way toward preventing (or healing from) Repetitive Strain Injury.
