Definitions

  • the present invention refers to an exercise machine.
  • the invention refers to an exercise machine suitable for strengthening the musculature of the lower or upper limbs, which has a preferred although not exclusive use for the rehabilitation of users who have suffered traumas or undergone operations to such limbs.
  • hypotrophy and hyposthenia of the quadriceps muscle are a constant occurrence after traumas or operations to the knee and it is necessary to counteract the loss of strength of the muscle with suitable rehabilitation exercises, so as to re-establish the correct working order of the limb involved and, therefore, the motor and walking capabilities of the patient.
  • a first type of exercises generally indicated with the term: open kinetic chain exercises, provides that, during the movement, the involved limb is subjected to a resisting force and the end (hand/foot) thereof is free to move in space.
  • open kinetic chain exercises provides that, during the movement, the involved limb is subjected to a resisting force and the end (hand/foot) thereof is free to move in space.
  • each extension and bending of the limb stimulates essentially only the agonist muscles, without involving the corresponding antagonist muscles.
  • These exercises are therefore very effective for strength recovery by the agonist muscles, since they substantially isolate the operation thereof, but may give rise to an undesired side effect, in this case related to potentially harmful stresses at the joints, above all in a rehabilitation step.
  • a second type of exercises generally indicated with the term: closed kinetic chain exercises, provides that, during the movement, the involved limb is subjected to a resisting force, while the end (hand/foot) thereof is unmovable or only able to move with great difficulty.
  • this type of exercises each extension and bending of the limb stimulates both the agonist muscles and the antagonist muscles.
  • the combined and simultaneous operation of the two muscle groups allows a greater stability of the joints to be ensured during exercise, limiting the occurrence of the aforementioned stresses; on the other hand, the strengthening action of the agonist muscles is less effective with respect to open kinetic chain exercises.
  • typical open kinetic chain and closed kinetic chain exercises are, respectively, the so-called "leg extension”, which provides that the legs are alternately extended and bent under the action of a resisting force, having a direction substantially coinciding with the direction of the thrusting force of the user, thus involving the knee joint only, and the so-called “squat”, which provides that one's feet are kept on the ground and the legs are bent and extended, respectively lowering and raising the pelvis and upper trunk under the action of weights of a suitable size, thus involving the knee, hip and ankle joints together.
  • the leg extension exercise substantially stimulates just the quadriceps muscle and therefore is very effective for strengthening such a muscle; however, whilst it is carried out, tangential forces develop that tend to make the tibial plate translate forwards, consequently stressing knee structures, as the anterior cruciate ligament and the medial meniscus.
  • limb rotation angles measured starting from the limb in completely extended state corresponding to a rotation of 0°
  • the aforementioned forces causing forward translation of the tibia arise for leg rotation angles between 0° and 60°.
  • rehabilitation after the anterior cruciate ligament reconstruction it is common practice not to use the leg extension exercise in the first weeks after the operation and in any case to avoid reaching rotation angles of between 0° and 30° even at a later stage. Therefore, this does not allow the advantages offered by such an exercise in terms of exercising the quadriceps to be exploited at an early stage.
  • the technical problem underlying the present invention is therefore that of providing an exercise machine for strengthening the musculature of the lower or upper limbs, which allows an open kinetic chain exercise to be carried out with isolation of the agonist muscles involved and simultaneously allows the transversal stresses occurring at the involved joints to be minimised, so as to avoid the undesired side effects outlined above in relation to such a type of exercise.
  • the invention therefore refers to an exercise machine comprising:
  • slidably associated is used to indicate that the carriage is slidably mounted inside and/or outside said arm.
  • the exercise machine of the invention allows t transversal stresses acting on the involved joint to be substantially reduced to zero by applying a resisting force to the arm that has a first non-zero component along a direction locally tangent to the trajectory followed by the arm, and a second non-zero component along a direction substantially perpendicular to the plane locally tangent to such a trajectory, i.e. along a direction passing through the centre of rotation of the arm.
  • tangential component and radial component respectively.
  • the tangential component of the resisting force counteracts the thrusting force applied by the user on the engagement element like in conventional open kinetic chain exercises, whereas the radial component acts substantially along the longitudinal axis of the arm, i.e. of the limb involved in the exercise, to which it is transferred thanks to the sliding of the carriage carrying the engagement element.
  • the resolution of the resisting force along the two aforementioned directions is not fixed, but rather varies as the angular position assumed by the arm whilst the exercise is carried out varies, since the angle formed by the resisting force with respect to the plane locally tangent to the trajectory correspondingly varies.
  • the exercise machine of the invention substantially operates in the same way as an exercise machine for performing open kinetic chain exercises, for example leg extensions, thus allowing the typical advantages of such exercises to be obtained in terms of strengthening of the agonist muscles, and, at the same time, advantageously allows the undesired side effects outlined above to be avoided, thanks to the action of the radial component of the resisting force applied to the arm.
  • the radial component shall preferably be of the centripetal type, so as to apply a compression on the limb; such a compression acts on the knee joint increasing its stability and limiting the occurrence of tangential forces causing forward translation of the tibial plate.
  • the acting sense of the radial component of the resisting force applied to the arm can be of the opposite type, i.e. centrifugal, should it be desirable or advantageous to stress the joint (like for example in the case of the shoulder) by applying a traction onto it instead of a compression.
  • the acting sense of the radial component is defined by the direction and sense of application of the resisting force to the carriage.
  • the applicator device of the resisting force comprises at least one flexible transmission element extended between the carriage and a generator of the resisting force.
  • Such a transmission element for example a belt, allows the desired resisting force to be applied to the carriage and allows the movement thereof to be easily followed whilst the exercises are carried out.
  • the exercise machine of the invention preferably also comprises angular adjusting means of the direction of application of the resisting force with respect to the plane locally tangent to the curvilinear trajectory.
  • Such adjusting means advantageously allow the direction of application of the resisting force as naturally defined by a generic angular position of the arm to be modified; this in turn determines a different resolution of the resisting force into its components locally tangential and locally radial to the curvilinear trajectory and therefore, in particular, a different intensity of the longitudinal force acting on the user's limb. This possibility is particularly useful for adapting the exercise machine operation to the requirements of different users or else, for the same user, to the different steps of an exercise or rehabilitation programme.
  • angular adjusting means to apply a relatively high longitudinal compression force on the lower limb to increase the stability thereof during the first steps of the rehabilitation programme, in which the joint is weaker, and then gradually decrease such a force as the joint recovers functionality.
  • the angular adjusting means comprise at least one deviator element slidably mounted in the frame and acting on the flexible transmission element to deviate the path thereof.
  • such a deviator element is adjustably positionable along a direction substantially perpendicular to the supporting surface. This arrangement is optimal to selectively deviate the path of the flexible element in the different operating configurations it assumes during the angular movement of the arm.
  • the deviator element comprises a roller, which advantageously allows the flexible transmission element to slide on it without scraping, so as to reduce the wear thereof through time.
  • the angular adjusting means comprise, alternatively or additionally, a fastening point of a first free end of the flexible transmission element, which is adjustably positionable on the carriage along a direction substantially parallel to the longitudinal axis of the arm. This allows a variation in the direction of application of the resisting force to be carried out by intervening on the fastening position of the transmission element to the carriage, without the need to use deviator elements along the path of the transmission element.
  • said adjusting means comprise a plurality of fastening points of the first free end of the flexible transmission element defined on the carriage and spaced apart from each other along a direction substantially parallel to the longitudinal axis of the arm.
  • such fastening points are pitchwise spaced apart, to advantageously allow a gradual adjustment.
  • the resisting force is applied to said carriage along an initial direction of application forming an angle of between about 30° and about 130° with respect to the plane locally tangent to said curvilinear trajectory.
  • initial direction of application of the resisting force is used to indicate the direction of the resisting force with respect to the plane locally tangent to the trajectory in an operating configuration of the exercise machine in which the arm is in its starting condition.
  • the initial direction of application of the resisting force to said carriage forms an angle of between about 75° and about 105° with respect to said plane locally tangent to said curvilinear trajectory. This allows an optimal intensity of the resisting force component along the longitudinal axis of the arm to be obtained in each angular position assumed by the arm during its rotation.
  • the generator of the resisting force comprises adjusting means of the intensity of the resisting force.
  • This feature in the same way as the possibility of adjusting the direction of application of the resisting force, advantageously allows the operation of the exercise machine to be calibrated according to the individual users or the different steps of an exercise or rehabilitation programme.
  • the flexible transmission element is an elastic element and the generator of the resisting force essentially consists of the flexible transmission element.
  • the resisting force is generated in a simple way, exploiting elements per se present in the machine and without resorting to external energy sources.
  • the elastic element extends between at least one fastening point defined on the frame and the carriage and is subjected to a predetermined pre-tensioning; this allows the elastic return force of the transmission element to be advantageously exploited to generate the resisting force to be applied to the arm.
  • the generator of the resisting force comprises at least one pair of idle pulleys of the flexible transmission element, interposed between said fastening point and the carriage.
  • At least one of said idle pulleys is adjustably positionable along a direction substantially parallel to the supporting surface of the machine.
  • the generator of resisting force comprises: a plurality of weights adapted to be selectively associated with a second end of the flexible transmission element, electrical drives, pneumatic drives, an inertial force generator, individually or in combination with each other.
  • the present invention refers to a method for exercising the musculature of a user's limb through an exercise machine comprising a support frame, said method comprising the steps of:
  • such a method allows both the agonist muscle groups of the limb to be effectively exercised, thanks to the action of the resisting force applied to the arm which the user makes rotate (as typically happens in open kinetic chain exercises), and the forces acting during exercise at the joints of the limb involved in the movement to be controlled, thanks to the action of the translation force applied along the longitudinal axis of the arm (as typically happens in closed kinetic chain exercises).
  • the at least one engagement element is fixed to a carriage slidably associated with the at least one arm and the aforementioned step d) is carried out by applying a resisting force to the carriage along a direction of application angularly staggered with respect to a plane locally tangent to said curvilinear trajectory.
  • an exercise machine according to the invention is generally indicated at 1.
