Effects of Upper Arm Ergometry in Stroke Victims

The incidence of cerebrovascular accident (stroke) can disable many functions of the body including brain function, speech, and neuromuscular function. Some common and severe effects of stroke include muscular weakness and muscular spasticity. Stroke induced disabilities often lead to a much more sedentary way of life than pre-stroke lifestyles due to losses in motor function. Recent studies have discovered that motor recovery after stroke is based on a cyclical, dynamic framework of interacting mechanisms in the brain cortex.1  In some cases, individuals post-stroke sequelae are unable to use cardio equipment which primarily activate the joints of the lower extremities. To maintain cardiovascular fitness the “Top” allows cycling activities using the upper body.There are many methods of stroke rehabilitation. he Laboratory for Wellness and Motor Behavior at Tarleton State University houses one method rather unique in its methodology. Designed by Technogym, the
Excite (Top) is a low impact cyclic upper body ergometer designed for varied use in gym, therapy and rehabilitation settings.
The Top uses both arms in unison, stimulating both left and right hemispheres of the brain. Due to the effects of stroke, many victims are left with hemiplegia (paralysis on one side of the body). Research has suggested that “unaffected arm exercise can stimulate the ipsilateral motor cortex and change the affected upper limb function and spasticity in stroke patients.”1 Through the technology and efficiency of the (Top), individuals are able to assess and track each individual's workout session. Some benefits provided by the Top include cardiovascular exercise, variation for increased calorie expenditure, correct warm-up, improved posture, prevention of  elbow and shoulder problems, and effective  rehabilitation of upper limbs. The (Top) will function for any individual, incorporating different muscle groups in either a seated or standing position . With cyclic strength or resistance exercises without sudden change of direction, the (Top) can tremendously reduce recovery times and return to optimal functionality.2
The (Top) is modifiable to any body position or range of motion making it a perfect combination for stroke victims with limited capacity in these areas. Combined with adaptable resistance, speed and rotation distance, the (Top) can provide consistent and considerable benefits for individuals through cardiovascular training, weight loss, toning, hypertrophy, strength, power, speed and rehabilitation.2
