Many of you are such ardent crocheters that you spend several hours a day working the hook. That's wonderful, but it also raises some concerns about maintaining good hand health. Activities that require small, repetitive movements can cause muscle disorders; therefore, it's important for crafters to be aware of the risks and to do what they can to minimize them.
Of course, if you feel pain when you crochet, the best thing to do is consult your doctor. The medical community has been trying to tackle the issue of repetitive muscle disorders for several decades and has made progress in understanding its causes and cures. From my own experience, as someone who crochets many hours a day and has a bit of arthritis, I have learned to follow certain guidelines. Let me share them.
- Maintain good posture while working.
- Avoid a tight grip on the hook or yarn; keep hands relaxed.
- Take breaks.
- Stretch the hands, fingers, wrists and other parts of the upper arm regularly.
- Use ergonomic hooks.
By being attentive to these factors, I have been able to continue to crochet for long periods without causing additional discomfort.
If you'd like to learn more about this topic, there is some interesting information at the U.S. Occupational Safety & Health Administration at this link. The focus here is on workers who do commercial sewing, but there is much that relates to crochet.
