[Modern carbon fibre orthoses in the management of polio patients--a critical evaluation of the functional aspects]

AIM

Evaluation of practicability and functional benefit with modern carbon fibre knee ankle foot orthoses in polio patients.

METHODS

In a retrospective analysis, fifty-five (55) polio patients between the ages of 42 and 80 years who had been provided with a carbon fibre orthoses for a minimum of three months, were asked about their acceptance as well as changes in functional capacity and comfort.

RESULTS

Clear improvements were shown in walking, sitting and automobile driving as well as comfort and dressing/undressing of the orthoses. Through the use of these new orthoses, the maximum walking distance increased significantly--at least partially due to less weight (40%). 95% of all treated patients were very satisfied or satisfied.

CONCLUSION

The use of carbon fibre material in the orthotic treatment of polio patients seems to be supported by the positive results of our study.

Estimation of the Direct Cost of Poliomyelitis Rehabilitation Treatment to Pakistani Patients: A 53-Year Retrospective Study

BACKGROUND

Pakistan is one of the last few countries in which poliomyelitis is endemic. Evidence indicates that out-of-pocket expenditures are a barrier to polio rehabilitation treatment, yet there are no reported figures related to the financial burden of this disease on patients in a recently polio-endemic country.

OBJECTIVE

This study investigated direct costs attributed to rehabilitation treatment of poliomyelitis among Pakistani patients and reported its duration along with the socioeconomic status of poliomyelitis survivors.

CONCLUSION

The cost of poliomyelitis rehabilitation in Pakistan is high; it has an economic effect on the lives of patients and their families. Despite good education, polio survivors in Pakistan appear to have low socioeconomic status, lower chances of employment and marriage, as well as fewer children. Further research is recommended to explore the burden of disease on society, i.e., indirect costs and suffering.

Vaccine-associated paralytic poliomyelitis: a case report of flaccid monoparesis after oral polio vaccine

This report describes a case of acute flaccid paralysis after administration of oral polio vaccine (OPV). A 4 month-old male patient with the decreased movement of left lower extremity for 1 month was transferred to the Department of Pediatrics. He received OPV with DTaP at 2 months of age. Flaccid paralysis was detected 4 weeks after OPV immunization. Attempts to isolate Sabin-like viruses in the two stool and CSF samples failed because those specimens were collected more than 2 month after the onset of paralysis. Hypotonic monoparesis (GIV/V), hypotonia and atrophy on the left lower extremity, and ipsilateral claw foot persisted for more than 18 months, while we followed him with rehabilitation therapy. This is the first case of officially approved, recipient vaccine-associated paralytic poliomyelitis in Korea.

A new mouthstick prosthesis for handicapped patients

Most mouthstick prostheses previously described in the literature have severely limited application or availability. They are either highly specific and sophisticated and difficult to fabricate or very crude and unifunctional. Most do not conform to basic functional and physiologic criteria as outlined, nor are they sufficiently flexible to meet the various needs and physical capabilities of of a wide spectrum of patients. The prosthesis described is adaptable, and with the basic bite-stick and the friction-grip lock, the patient can change the form and function of the device to perform various tasks independently. The prosthesis is simple, inexpensive, and easy to fabricate and repair, and it needs no specialized or sophisticated parts. It enables handicapped patients to attain a greater degree of self-sufficiency than was previously possible, which improves their mental outlook.

Secondary conditions and life satisfaction among polio survivors

Persons living with the effects of polio are often at increased risk for the development of secondary conditions and disabilities that can lead to further decline in health status, independence, functional status, life satisfaction, and overall quality of life. The purpose of this study was to explore the frequency of selected secondary conditions, factors associated with these conditions, and the relationship between secondary conditions and quality of life among polio survivors. Data from a large convenience sample (N = 2,153) indicate that secondary conditions are prevalent and associated with decreased life satisfaction. Prompt identification and treatment of secondary conditions before they progress to greater impairment and/or disability and attention to an overall healthful lifestyle is important to preserve function and maintain quality of life of polio survivors.

An insole pressure measurement system: repeatability of postural data

This study analyzed the ability of an in-shoe plantar pressure measurement system to provide repeatable measurements of postural sway data for both healthy and clinical patients. Each participant's in-shoe pressure data were recorded for three trials during each test session during quiet stance. Healthy individuals (n = 9) participated on three consecutive days while clinical participants (n = 5) were tested on one day. Nine response variables were measured to assess their postural stability. Intrasubject measures were evaluated using the Kerlinger reliability procedure. Values provided directly by the Parotec System for a single day of testing yielded the following average coefficients: r = 0.95 (left), r = 0.97 (right) with mean coefficient values from the three day tests of: r = 0.98 (left), r = 0.98 (right). Variables calculated from raw data on a single day produced mean coefficients of: r = 0.77 (left), r = 0.76 (right) and over three days of: r = 0.65 (left), r = 0.66 (right). The ability to record highly reproducible data of postural sway parameters should assist clinicians to treat patients more confidently for balance deficiencies.

A method to measure the accuracy of loads in knee-ankle-foot orthoses using conventional gait analysis, applied to persons with poliomyelitis

OBJECTIVES

To determine (1) the forces and moments passing through knee-ankle-foot orthoses (KAFOs) during walking and (2) the accuracy with which these loads can be measured using conventional gait analysis techniques.

DESIGN

Comparative case series.

SETTING

Rehabilitation facility with human movement laboratory (gait lab).

PARTICIPANTS

Four patients with poliomyelitis wearing KAFOs.

INTERVENTIONS

KAFOs were instrumented with a load cell, and walking data were concurrently collected using conventional gait analysis.

MAIN OUTCOME MEASURES

Load measurements and gait parameters.

RESULTS

Predominant orthotic loads (knee joint forces and moments) were composed of knee flexion moments and axial compression forces. With conventional gait analysis, peak knee joint moments were substantially underestimated compared with those directly measured using the load cell. Defining the knee axis anatomically versus at the orthotic axis, tracking it dynamically, and compensating for each patient's corrected knee flexion contracture resulted in considerable improvements in the gait lab estimates of knee joint moments.

CONCLUSIONS

A practical method that directly measures moments and forces in conventional KAFOs has been applied to show that conventional gait analysis techniques substantially underestimate knee joint moments in the KAFOs of persons with poliomyelitis. Underestimation of orthotic loads could result in underdesigned orthotic components and ultimately higher incidence of component failure in clinical applications.

The Norwegian Polio Study 1994 part II: early experiences of polio and later psychosocial well-being

STUDY DESIGN

The Norwegian Polio Study 1994 was a nation-wide survey of the medical and psychosocial situation of polio survivors.

METHOD

A questionnaire, consisting of 133 questions with sub-questions, was sent to a total of 2392 polio victims, most of them registered in 'The National Society of Polio Victims' in Norway. 1449 (61%) answered.

OBJECTIVES

To investigate the relationship between early polio experiences, such as duration of hospitalization and perceived support, and later psychosocial well-being.

RESULTS

Three hundred and ninety-one persons (27%) reported they had been psychologically harmed by the treatment received at the time they contracted polio (Harmed group), while 1053 persons (73%) did not (Non-Harmed group). Persons in the Harmed group were significantly younger at polio onset, were hospitalized for a longer period and had less parental visit and support. Today they use more medication, report more pain, general fatigue, sleep disturbance and concentration problems, more psychosocial distress, less satisfaction with life and less social support than persons in the Non-Harmed group.

CONCLUSIONS

The results demonstrate that a subgroup of polio survivors has been vulnerable from childhood, with possible consequences for their physical, psychological and social wellbeing later in life. Recommendations for long-life treatment of children with similar diseases should include follow-up not only of their physical disabilities, but also on psychological and psychosocial needs.

A rejoinder to "Exercise Programs for Patients with Post-Polio Syndrome: a case report"--a short communication

This communication is in response to the article by Michael T Gross and Charles P Schuch entitled "Exercise Programs for Patients with Post-Polio Syndrome: A Case Report" published in the January 1989 issue of Physical Therapy. The investigators examined the effects of a rigorous isokinetic training program on peak torque of the knee flexor and extensor muscles of a post-polio patient. The literature on post-polio syndrome, however, does not support the use of either conventional muscle strengthening regimens or rigorous isokinetic exercise programs in the management of post-polio syndrome. In addition, based on the observation that there was no appreciable increase in muscle strength in either the affected or the apparently unaffected leg, the investigators concluded that their rigorous exercise program was not deleterious. The lack of a normal training response, however, is consistent with bilateral muscle fatigue secondary to overuse rather than muscle weakness secondary to disuse. This result is consistent with the need for a balance between rest and low-intensity exercise, which will help to maintain or enhance function while slowing rather than hastening further deterioration. We hope that this rejoinder clarifies some of the misconceptions that may arise from the Gross and Schuch article and that physical therapists consider very carefully the rationale for any type of exercise program for post-polio patients.

Crawling patterns in neglected poliomyelitis in the Solomon Islands

Two hundred and twenty-two adult crawling poliomyelitic cripples were investigated. Analysis showed that bilateral lower limb paralysis with or without trunk involvement was the most common residual lesion. Remarkably paralysis was confined to a single lower limb in six cases. The various crawling patterns can be classified into six broad groups which are described and illustrated. It is suggested that in a developing country this classification has a practical application in the assessment of patients for rehabilitation to crutch walking. Subjects in the "true quandruped progression" and "squatting gait" categories generally have an excellent potential for rehabilitation, as often do those in the "infant-like crawl" group. Caution should be exercised in attempting crutch walking for those in the "body-dragging" group, and there seems little indication for attempting to establish upright walking for those in the "buttock pivoting" and "minimal movement" groups.

Post-polio syndrome. The battle with an old foe resumes

How many of the thousands who contracted polio during the epidemics 30 and 40 years ago will experience post-polio syndrome? What causes these delayed effects, and how quickly will they progress? None of these questions can be answered with certainty. At present, several factors appear to be at work. Patients are generally in one of two groups: The first group has deterioration in the function of muscles that were affected by the disease. This muscle weakness may be caused by a loss of motor neurons, due to aging, from an already depleted neuron pool. The remaining motor units then become stressed from overuse. The second group has problems in new muscle groups or those thought to be recovered from the disease. Problems in the second group appear to have a cause other than simple aging, possibly autoimmune, but longer follow-up is required to assess these patients. Evaluation of post-polio patients should be based on differentiating new neuromuscular disorders from exacerbations of the original disability. Although changes associated with aging cannot be halted, once post-polio syndrome is diagnosed, patients can be encouraged to follow appropriate dietary and exercise programs to maintain their present function, and they can be reassured of the relatively benign course of their problems.

Long-term follow-up of patients with nonparalytic poliomyelitis

OBJECTIVE

To examine patients with previous nonparalytic poliomyelitis in search of muscle atrophy, weakness, and other late symptoms of poliomyelitis.

DESIGN

A mailed questionnaire followed up with neurologic and neurophysiologic examinations of respondents who reported symptoms possibly related to the late sequelae of polio.

SETTING

Neurology department at a university hospital.

PARTICIPANTS

Thirty-nine of 47 patients diagnosed with nonparalytic poliomyelitis and hospitalized at a Norwegian hospital between 1950 and 1954, during the Norwegian polio epidemic.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Electromyography to determine function of the anterior tibialis, vastus lateralis, and biceps brachii muscles; nerve conduction studies of the sural, peroneal, and tibial nerves; motor and sensory nerve conduction velocity, and compound muscle and sensory nerve action potentials, and distal latencies.

RESULTS

Twenty-five of 47 patients (53.2%) reported symptoms possibly related to the late sequelae of poliomyelitis. Eight of 20 examined symptomatic patients had normal neurologic and neurophysiologic findings, whereas 9 others had other medical conditions that could explain the symptoms. Three patients (6.7%) had neurologic and neurophysiologic findings and development of symptoms consistent with motoneuron damage.

CONCLUSION

Some nonparalytic patients may have subclinical acute motoneuron damage with subsequent development and manifestation of motor weakness and neuromuscular symptoms many years later. These symptoms should be considered a differential diagnosis in patients who have a history of nonparalytic poliomyelitis.

Franklin D. Roosevelt: diagnosis, clinical course, and rehabilitation from poliomyelitis

In this case report, we examine Franklin Delano Roosevelt's prognosis, clinical course, and rehabilitation from poliomyelitis, and we examine the criticisms of errors in his diagnosis and management on the basis of current knowledge of the pathophysiology of poliomyelitis. Medical and historical records reveal the onset of severe paralysis, which progressed over several days, with minimal improvement in hips and lower limbs, but recovery of facial, upper limb, and upper trunk muscles. There is no scientific basis for assertions of mismanagement that led to more severe paralysis; the paralysis was most likely caused by strenuous activities in the preparalytic phase of his illness.

Braces, wheelchairs, and iron lungs: the paralyzed body and the machinery of rehabilitation in the polio epidemics

The successful fund raising appeals of the March of Dimes employed images of cute crippled children standing on braces and forearm crutches, sitting in wheelchairs, or confined to iron lungs. Those who had to use these devices as a result of polio, however, were often stigmatized as cripples. American cultural antipathy to these assistive devices meant that polio survivors often had to overcome an emotional and psychological resistance to using them. Whatever their fears, polio survivors quickly discovered the functionality of braces and wheelchairs. By confronting the cultural stigma associated with these devices and in some sense embracing these mechanical "friends," polio survivors compensated for their paralyzed bodies and became active in the wider world of home, school and work.

Return to work: experiences of a hospital rehabilitation officer

Successful return to work after illness or injury often depends on an efficient exchange of information between doctor and employer. Rehabilitation officers with experience in industry have been employed by the Royal National Orthopaedic Hospital, Stanmore, for several years and have established their value in acting as direct links between hospital and industry.

Problems in the rehabilitation of the physically disabled in rural areas of India

Some 550 disabled patients were examined by a rehabilitation team by organizing a rural camp at Meerut. This rehabilitation team consisted of orthopaedic surgeons, doctors, a prosthetist, an orthotist, a medical social worker and other skilled workers. Out of the 550 disabled patients, 271 were amputees, and 184 cases had poliomyelitis. Males predominated by 4:1. Disability was most common up to the age of 30 years. Of the 271 amputees, 146 were of upper limb while 125 were of lower limb. Only 86 lower limb amputees were suitable for fitting a prosthesis, while 39 others needed surgery of physiotherapy. Only 87 of the 184 polio cases were found suitable for appliances, the remainder needing surgery or physiotherapy. Ways of reducing the numbers of disabled were examined and improved rehabilitation procedures suggested.
