Abstract
A lower body exercise apparatus comprises a seat mounted to a base such that the seat can be slid to and fro in a cyclical motion along the base by a user performing a leg extension exercise. An energy storage device is provided to resist motion of the seat/user during an initial phase of the motion cycle and assist motion of the seat/user during the remainder of the motion cycle. The apparatus further includes a functional electrical stimulation (FES) unit so that the exercise apparatus may be used by a person with lower limb paralysis.
Description
Lower Body Exercise Training iscription: Lower body exercise trainer is a device designed in the form of a rowing machine. it uses the concept of conservation of energy in a novel manner and combines electrical stimulation of muscle with mechanical control to achieve energy-efficient motion for rehabilitation and/or training and muscle strengthening. An energy storage element stores kinetic energy produced during an initial phase of the motion cycle and releases it for during the remainder of the motion cycle. The element further provides specified level of resistance (adjustable damping) to forced motion thus, the demand on musde force provided by the user. The required force in case of a spinal cord injured person may be provided by electrical stimulation of muscle using Functional electrical stimulation technology FES, where the device will act as a rehabilitation machine, and in case of an able person, where no stimulation of muscle may be necessary, the device will help in strengthening the muscle. * S.

BenSon, Baker at at, 1981 (see bibliography) What Is Functional Electrical Sdmulatlan? Functional electrical stimulation (FES) can be applied to a wide variety of research and treatment approaches. Frequently asked questions about FES Include: What Is FES? How can FES he irs? WIN FES help irs to walk again? FES Is the mOst Important application in the field of dllnlcai treatment with currents or magnetism. This technique artificially generates neural activity in order to overcome lost functions of paralyzed, Incontinent or sensory Impaired persons. The term "functional electrical etImUlationN can be used to describe a variety of therapeutic techniques and experimental treatment approaches. For example, scientists and physicians. hays developed a devic, called a cochisar implant for the ear that enables Individual, with sensorineural deafness to hear certain kinds of sounds, and thus interpret the spOken word. Phrenic nerve stimulatora are implanted devices that help people breathe without a respirator. Men with spinal cord injury who experience sexual dysfunction can, using a FES technique, Induce ejaculation. Some researchers are using electrical stimulation to assist paralyzed indMduals regain control of lost bladder fUnction.
One important and promising area of FES research involves restoring function to a parson's paralyzed arms and legs. First demonstrated as a possible treatment by Adrian Kantrowfti in 1960, ft is currently being researched In depth by Investigators throughout the world.
EXCICISS4MOtO, Therapies An Importa consideJon In the use of FES fur motor control is getting one's muscles back in shape after months or years of non-use. Once a Sd has occurred, the muscles below the level of Injury generally Atrophy and circulation becomes impaired due to inactivity. Many people also have problems with Osteoporosis, or brittle bones.
Consequenuy, if one intends to use FES tostandorwon paralyzed limbs, itis necessary to recondition the body and get it accustomed to the use of external stimulation.
One widely used exercise system Is currently available commercially through Sintles Scientific vi Tulsa, OK, which manufactures and sells a relatively inexpensive FES bicycle for home use. This device coordinates leg and arm movement to activate cycling. It is hoped that the use of an FES bicycle may reduce the number of medical complications resulting from immobilization arid Inactivity and lead to an improved and healthier lifestyle.
To address these areas, researchers at Wright State University in Dayton Ohio developed an exercise bicycle for use by SCI research subjects. With external electrodes attached to the appropriate muscles on their legs, these individuals wrodeN the bicycle both to condition their bodies and to assist researchers an learning more about what kinds of stimulation were most effective in creating certain movements.
Therapeutic Alliances, Inc. produces and markets a FES cycling device for therapeutic use, the ERGYSI based on the Wright State University research. The product, described as a leg cycle ergometer, has been found effective for home and clinical use. The ERGYS employs computer controlled electrical impulses to the leg muscles thereby stimulating cycling movement Therapeutic Alliances is located in Fairbom, OH.
Because of all the publicity that has surrounded the concept of functional electrical stimulation, it Is Important to realize a FES exercise program Is a separate and distinct activity from FES for Improved motor control or any other continuous application of electrical stimulation. Clinical studies have indicated that users of FES bicycles have been able to Increase and maintain muscle mass, tone and cardiovascular fitness. The studies have also indicated that regular participation in a FES exercise program may improve immune functioning.
It is important to be aware that such machines are potentially dangerous if not used correctly. Additionally, not all people are appropriate candidates for a FES exercise program. Individuals Interested in exercising with FES equipment should be evaluated by a physician specializing in SC1 and should undergo an exercise program under the supervision of a clinician with expertise in the area of FES and paralysis.
Many clinical settings currently use FES exercise systems with what they consider to be positive results. lndMduals interested in participating in such an exercise program may wish to contact the FES Information Center to obtain information about FES programs in their community.
FES dearly has many possible applications. When reading about FES or hearing about a program in WhiCh It is used, It Is important to understand what kind of FES is being used and whether the program at the facility is a research project, a regular clinical offering, or a combination of both.
Claims (1)
- Claim(s): The device may be used for purposes of rehabilitation and strengthening of muscle in the lower extremities of people with spinal cord injury (Sd), where electrical stimulation of scle to provide necessary forced motion is combined with capabilities of an energy storage element to assist the motion during part of the motion cycle. The device may further be used as a muscle strengthening or training machine with able people (elderly or other age groups), in which case the energy storage element will act as a damper providing adjustable resistance to forced motion. In this manner, the force demanded of muscle to produce certain motion pattern may be varied to suit personal fitness. The device could further translate, in an intelligent manner, voluntary and trained motion of upper extremities into motion of lower extremities. Existing products, in the form of exercise machines, treat the person as passive entity, where the muscle takes either limited or even no active part in the exercise. This does not help rehabilitation and strengthening of paralysed limbs. The proposed solution allows a person's muscles to have active role in an exercise regime and this helps in efficient rehabilitation and strengthening of the muscle. The solution further allows contribution of any voluntary intention to be incorporated/translated into desired motion. * ** * * . * ** *** S * S *S. **.* * ** II **1I *e..I SIll I. 5 * S S *5
