Strength training with the kBox4 for PNP-patients

Imagine that you have no feeling from your elbows to your fingers and no feeling in your hips, legs, and feet! Imagine that you were completely healthy until you were 48 years old, used to conduct hockey practices on skates, and then gradually you lost all the feeling and a lot of the functions in your arms/hands and your leg balance. Mårten Fredriksson explains:

Polyneuropathy (PNP) is a term used to describe a physical state where peripheral nerves lose some of their ability to function.

PNP impacts, among other things, sensory and motor nerves with consequences such as difficulties with walking and tendencies of falling. Distal muscle weaknesses and atrophy of the feet and lower legs are common as well. 

In the case of Lars G, he has a form of polyneuropathy that debuted in his midlife, however, the debut of polyneuropathy can occur both in childhood and later on in life. With the specific type of polyneuropathy that Lars G has, the pace of progression is usually slow but over time there is often a relatively extensive increase in the level of disability. 

Lars G, who is now 68 years old, has gradually over the past 20 years lost muscle mass, function, and feeling in his arms and legs, he has fallen multiple times on some occasions causing serious injuries such as a broken left tibia. Since a while back now Lars G has been working with strengthening his body and muscles in order to push off the inevitable side effects of the illness. His goal is to recycle his muscle mass, to become stronger in the muscle mass that he has left, to activate the motor nerves, and increase tendon stiffness which are all important components of his current balancing issues. 

Lars G is working with “big” exercises where he gets to use muscles connected to multiple joints and thus is challenged to produce and develop muscle force in balance requiring everyday movement patterns. 

Lars G is aiming at the goal to push the level of disability as long and as far off as possible in order to enable himself to be independent, and able to move and choose what he wants to do without any personal assistance and various assisting tools. He has hung up his skates but with strength training, he hopes to once again be able to experience cross country skiing through nature during the early spring. 

5 Reasons why Lars G is using a kBox and Flywheel Training as a workout.

  1. Safety: If he were to lose balance and needs to catch himself he can just end the exercise or let go of the grips/handles without causing any damage to himself, the equipment, or anything in his immediate surroundings. 
  2. Variable Resistance: Since the resistance on the kBox is variable, it is Lars G who decides how hard to train and he can end any movement when he feels the need to. 
  3. Portability & Small Footprint: He can work out in his own home which doesn’t require any transportation to a public gym, such gyms are often not adapted to individuals with similar motor disabilities as Lars G.
  4. Lightweight: The equipment doesn’t weigh (9-15 kg) much and is easy to move to a desired place of training as well as storing it away. 
  5. Easy to switch between drills and users: Everyone in his family can use the kBox as well, regardless of their level of training and individual goals with their training (health/performance).

Polyneuropathy affects 123 people among 100.000 in the population, in Sweden that is approximately 12,000 cases in the whole population.
