INTRODUCTION INTRODUCTION

PARTIAL WEIGHT BEARING GAIT THERAPY AND BALANCE TRAINING (1)

The loss of the ability to ambulate can be one of the most debilitating aspects of many

Neurological and musculoskeletal disorders. Any of the three main components of locomotion

- posture, balance and coordination - can be affected by a variety of neurological or

musculoskeletal pathologies resulting in the disruption of an individual’s ability to walk

Normally. Partial Weight Bearing Gait Therapy (PWBGT) has shown great promise in helping

a wide Variety of impaired patients as they relearn walking function. It is an appropriate

modality to use whenever gait therapy is prescribed for patients who are unable to support

their own body weight or lack the upper body strength to support themselves during assisted

ambulation. In addition to aiding gait pattern regeneration, partial weight bearing therapy

allows patients to perform cardiovascular workouts in conjunction with a treadmill, enhance

balance and improve posture. Partial Weight Bearing Gait Therapy makes use of a patient

suspension system, such as the IMI Un-weighing Trainer, to reduce the amount of weight born

by a patient and provide proper upright posture. The suspension system is used to remove a

pre-determined portion of the weight load from the patient’s legs and redistribute it to the

patient’s trunk and upper thighs, thus freeing up the arms and legs.

INTRODUCTIONINTRODUCTIONPARTIAL WEIGHT BEARING GAIT THERAPY AND BALANCE TRAINING (2)

With the patient supported by the suspension system, horizontal movement is provided by

setting the treadmill to a slow speed. The constant rate of movement provided by the treadmill

provides rhythmic input to reinforce coordinated, reciprocal movement of the legs. The

therapist can provide further assistance, especially with severely involved patients, by manually

placing the patient’s feet and/or assisting the patient in weight shifting. Once the patient begins

to gain a feel for the proper coordinated movement pattern the Treadmill speed and/or the

amount of weight borne by the patient can be gradually increased to better simulate natural

walking conditions. The increase in weight bearing and treadmill speed also helps the patient to

relearn dynamic balance. Having achieved preset goals on the treadmill, the patient can be

progressed to ambulating over ground with the aid of the suspension system. Ultimately, it is

hoped the patient will be able to ambulate over ground independently or with an assistive

device. PWBG Therapy sessions typically last 30 minutes to an hour and are scheduled three

to four times per week. Each hour of the session can be divided into three or four periods of

activity followed by a rest period. Activity periods can be as short as three minutes with five

minutes of rest but should not exceed 15 minutes if the patient is supported or partially

supported by the suspension system. Each period should end at its predetermined time,

especially if the patient’s gait deteriorates or the patient or therapist feels fatigued. Because the

repetition of coordinated walking patterns is the most essential element to the success of this

therapy, be sure to provide consistent training without interruptions or breaks.

INTRODUCTION INTRODUCTION

PARTIAL WEIGHT BEARING GAIT THERAPY AND BALANCE TRAINING (3)

Patients are evaluated over a Two-week period and are expected to make some gains in

their ability to coordinate movement during treadmill walking in this time frame. Continue

the program for Eight to 12 weeks if sufficient progress is demonstrated. Continue for up to

an additional Four weeks for cases showing slower improvement. For acute patients who

show little on no progress after the first Two weeks of therapy, time may be better spent on

different learning activities. The Un-weighing System can be used in the recovery of

balance and posture for patients with compromised posture or balance mechanisms. Toss

the patient a ball to catch or provide perturbation manually to challenge their balance. The

suspension system will prevent the patient from falling while providing proprioceptive cues.

The amount of support can be reduced as the patient progresses.

NOTE : Extreme caution should be taken to assure the stability of autonomic reflexes

(in acute stages) as well as bone and muscle integrity (in chronic cases).

BENEFITS OF DYNAMIC UN-WEIGHING THERAPYBENEFITS OF DYNAMIC UN-WEIGHING THERAPY

Partial Weight-Bearing Therapy, also known as Un-weighing, is a concept of

rehabilitation that uses an external device to support a percentage of the patient’s body

weight, allowing them to perform a variety of therapeutic activities in an upright and safe

environment.

Typically used with Neurological Pathologies, the patient’s body weight is supported

between 20-40% to assist with developing proper gait patterns and improvements in

cardiovascular and muscular endurance with less physical demand.

The ability to initiate exercise early in the rehabilitation process can benefit the patient

by allowing development of neural pathways through muscular patterning.

Research has shown the benefits of Un-weighing to occur in a variety of physiological

ways.

PHYSIOLOGICAL BENEFITSPHYSIOLOGICAL BENEFITS

Symmetrical Loading of the Lower extremities - This assists with equal weight distribution over the base of support. Equal weight distribution in turn provides the proper biomechanics to correct step length deficits and time distribution between limbs.

Reduction of Muscular Splinting - Parasympathetic tones typically associated with neurological pathologies can be reduced through partial-weight therapy.

Minimizing parasympathetic stimuli helps to reduce muscular tension in turn allowing

for increased range of motion and focus on motor control exercises.

Reduction of Cardiovascular and Metabolic Demands - Relieving graded portions of body weight allow the patient to exercise with less stress to the cardiopulmonary system, this is beneficial for extremely deconditioned patients as it allows them to initiate exercise without increasing cardiopulmonary demand. VO2 levels are maintained better at 40% un-weighing than at 0%, the patient can then also exercise for a longer period of time. This application can be beneficial for cardiac and pulmonary rehabilitation, as well as obese patients as exercise can be prolonged to enhance conditioning.

OTHER BENEFITSOTHER BENEFITS

Acute Injury and Post Surgical – Un-weighing can also provide a safe environment to start acute therapy following injury or surgical procedures. This is especially true with patients suffering from low back pain, whether it’s acute or chronic. Un-weighing provides an environment around the injured joint with reduced gravitational effects, this can be coupled with exercise to enhance joint stability. Vertical traction is accomplished to provide patient relief. This same approach can be taken with other orthopedic injuries. By using the Un-weighing System you can be assured that your patient is working in a dynamic environment unloaded to physician specifications. Since the weight of the patient is supported, there is increased safety for them and the clinician, should a fall occur.

Balance Training - The Un-weighing System provides a safe environment during balance training. Securing your patient in the Un-weighing System will eliminate the risk for falling during balance training. The somatosensory input provided by the harness provides proprioceptive feedback in regards to location of the trunk over the base of support and will allow your patient to work with more confidence during rehabilitation.

Digital Display of Un-weighing Load - The digital display incorporated on the Un-weighing System provides feedback in regards to the amount of weight being relieved from the patient. This is beneficial as it allows for consistency between treatments thus providing a therapeutic environment to improved gait mechanics and neurological patterning.

DETERMINATION OF BODY WEIGHT DETERMINATION OF BODY WEIGHT SUPPORT SUPPORT

1. Heel / Ground contact during ambulation is lost in patients when weight relief is

in excess of 40% body weight.

2. Chose a level of weight relief in which the patient achieved heel/ground contact

bilaterally for ten consecutive steps.

3. When determining body weight support, keep in mind the patient's pathology

level of involvement and comfort. A patient who is considerably challenged

may require a greater percentage of weight relief.

4. The digital panel shows the Total Body-weight of the Patient in Green window

and the Red window shows the Body weight being lifted.

USING THE SUPPORT HARNESSUSING THE SUPPORT HARNESS

1. Two Harnesses are supplied with the system. (Small harness for thin patients & Large for fat patients)

2. To assure patient compliance and successful rehabilitation, the Support Harness must be properly adjusted to provide a comfortable environment for your patients. There are Two harnesses to accommodates a wide variety of patient sizes and shapes.

3. The Velcro straps are easily adjusted while the harness is on the patient and allow for quick removal once therapy is completed.

4. The harnesses can accommodate patients with torso sizes measuring from 24" to 50".

Follow the directions below to ensure a proper and safe fit.

CAUTION:

A snug fit is necessary to provide safe un-weighing and improved patient compliance.

It is necessary to ensure that the straps do not lay over pressure points or where friction may occur.

These areas may include, but are not limited to, under arms, between legs, and at the edges

of the harness.

For purposes of hygiene and comfort, it is recommended that the patient wear clothing under the contact areas of the harness at all times.

Adjustment : Using the Velcro straps, secure the harness snugly around the patient’s torso. The torso straps can be adjusted from the front or back of the harness.

2. Between Leg Straps: Allows for weight distribution through the legs.

Adjustment : Using the Velcro strap, secure the harness snugly between the Legs.

3. Shoulder Straps : Allow for harness height adjustment while patient is secured to the Un- weighing System. Should the patient need additional support on one side

the strap can be shortened to provide additional unilateral support.

Placement : Adjustment of the shoulder straps should allow the cross bar of the Un- weighing System to be positioned approximately two to three inches above the patient’s head before the un-weighing load is applied.

Adjustment : The shoulder straps can be lengthened or shortened using the end of the strap located near the seat belt buckle. With Remote Switch adjust the Suspension bracket with cross bar to patient height.

NOTE : Be aware of incontinence concerns. Use of the un-weighing harness can put pressure on the patient’s abdominal area, including the bladder. Should a harness become

soiled, it can be hand-washed in a sanitizing detergent, then air-dried.

NOTE : Patient set-up should be conducted over the desired walking surface (i.e, treadmill or floor) as moving from the floor to the treadmill will require the set up procedure be repeated.
