Question from Bernd J.: Due to an acute slipped disc with massive pain and complete loss of function in my right leg, I had an operation on my spine. After the operation and hospitalisation, I was pain-free, followed by rehabilitation and physiotherapy. In the course of this training, the function of my right leg gradually improved. When I asked various doctors and physiotherapists whether I could ride an MTB and/or road bike again, I received completely different answers, from cycling being "murder for the spine" to "sure, you can get back on the bike, but only if it's a fully". I was unable to clarify what this advice was based on. So my question is: is it justifiable and sensible to cycle again, or is it too risky?
Dr Christian Merkl: Herniated discs resulting in surgery are a drastic event. If the operation is initially without complications, it is not uncommon for problems to occur between the fourth and sixth week, usually due to premature mobilisation and activity. I therefore advise against any activity at first; I usually even prescribe a corset that immobilises the spine. The reason for this is to allow the surgical site to heal with as little scarring as possible. However, the greater the initial activity, the greater the risk of another prolapse or increased scarring.
Although this type of treatment initially involves a reduction in muscle strength, I believe that this can be compensated for after three months by intensifying the training. To start with, I recommend purely isometric strength training of the core muscles. You can then slowly start pedalling again on the ergometer - possibly with a corset. I am in favour of later cycling training with increasing progression and certainly don't see it as "murder for the spine". Especially if you ride in the top handlebar grip and change position frequently, for example by riding in the cradle. Overall, you should be able to cycle normally again after six months.
