First, we should explain the terminology because it is rather confusing. A kyphosis is a normal forward bend in the upper back. You would be right to hence ask the question, why would you want to correct a kyphosis, if this is normal to have it? The problem arises from an excessive kyphosis in the upper back, or thoracic spine as it is known in medical terms. While the upper back should naturally bend forward, this can often become exaggerated, leading to a “hyperkyphosis”. The only problem is that the term hyperkyphosis is rarely used. Instead, the term has been shortened to “kyphosis”.
