Effects of physical therapy on quality of life in osteoporosis patients - a randomized clinical trial.

SUMMARY: The aim of this prospective randomized single-center study was to investigate whether sling exercise therapy is superior to conventional exercises in osteoporosis patients. BACKGROUND: Patients with osteoporosis frequently experience fractures of the vertebral body, which may cause chronic back pain and other symptoms. These, in turn, may lead to immobilization, muscular atrophy, and restrictions in activities of daily living. The situation can be improved with specific medication and physiotherapy. We explored the effects of a variety of physical treatments on activities of daily living in patients with osteoporosis. METHOD: Fifty patients were randomly allocated to two treatment groups. Group A received traditional physiotherapy (PT) while group B underwent sling exercise therapy (ST). Both treatments were given twice a week for three months. The results of the treatment were registered on the quality of life questionnaire (Qualeffo-41) devised by the International Osteoporosis Foundation. After a further three months with no specific exercise treatment, we again tested all patients in order to draw conclusions about the long-term effects of both types of exercise. RESULTS: Forty-four patients (88%) completed the study. Patients were assigned to small groups (a maximum of 5 patients in each group) and thus received individual attention and motivation. Quality of life was improved in both groups; a significantly greater improvement was registered in patients who performed sling exercises (Global score Qualeffo: p = 0.002). CONCLUSION: The test results confirm the known positive effects of physical therapy on the quality of life of osteoporosis patients, as well as the fact that sling exercises are a sound alternative treatment for this condition.

Biofeedback load technique in the rehabilitation of osteoporotic patients (biomechanical analysis).

Based on a simple biomechanical analysis, available to physicians, the article recommends carrying a backpack regularly as a part of the complex rehabilitation of osteoporotic patients. Carrying a backpack in front or on the back is recommended for patients with uncomplicated osteoporosis, carrying a backpack only on the back is recommended for patients with osteporotic vertebrae fractures. The importance of carrying a backpack is based upon remove the muscular dysbalance of the trunk muscles and upon increasing the bone strength by compressive force acting upon the vertebrae and proximal femur and activating osteoblasts to osteoformation. The backpack load magnitude is differentiated--patients with vertebrae fractures put a weight up to 1 kg into the backpack, patients without vertebrae fractures up to 2 kg.

Percutaneous vertebroplasty: optimizing the procedure after treatment of 250 vertebral levels under fluoroscopic guidance.

PURPOSE: Percutaneous vertebroplasty (PVP) is a minimally invasive treatment for symptomatic vertebral compression fractures (VCFs). The aim of this study was to assess the effectiveness, complications and progress of results of PVP optimized in terms of technique, costs, time and strategic protocol after 3 years of procedures performed under fluoroscopic guidance alone. MATERIALS AND METHODS: We treated 250 VCFs in 120 consecutive patients after assessing clinical and radiological indications. The effectiveness of the procedure was determined by statistical analysis of numerical scores for pain, mobility and drug consumption before and after treatment. RESULTS: No major complications and only three minor complications occurred. Clinically relevant improved mobility and reduction of pain and analgesics were observed, with overall significant results (p<0.0001) in all patients at 24 h after PVP and in 83 available patients at 6 months. A total of five asymptomatic refractures of cemented vertebrae and 14 new symptomatic vertebral fractures at different levels were observed between 1 and 10 months after the procedure. CONCLUSIONS: PVP is a safe, rapid, effective and costeffective therapy for VCFs, requiring only brief hospital admission and with long-lasting clinical results, when performed under good-quality radiological guidance, when correct indications are respected and when it is associated with rehabilitation therapy in the follow-up. It is a valid alternative to conservative therapy, which is burdened by high healthcare costs and often requires long-term immobilisation of frail and elderly patients at risk of clinical complications.

Elite male adolescent gymnast who achieved union of a persistent bilateral pars defect.

An adolescent 15-yr-old male competitive gymnast presented to a university-based multidisciplinary spine institute with a persistent low-back pain for 18 mos. Although the results of x-rays were negative, his pain rendered him unable to compete in his sport any longer. A computed tomography scan was performed, which showed a bilateral pars fracture at L5, without spondylolisthesis. A nuclear medicine bone scan revealed negative findings, confirming chronic nonunion. The patient completed a 4-wk course of physical therapy 6 mos before our intervention, without any relief of pain or radiologic evidence of healing. The patient was treated with a bone stimulator for 4 hrs/day and was recommended to wear a warm-and-form-type brace. Isometric core trunk exercises were also initiated. Only after 6 wks of treatment, the subject showed clinical improvement at the follow-up visit. Computed tomography scan performed 12 wks after the initial scan showed complete union of the fracture correlating with clinical improvement. Two years later, the athlete remains completely pain-free, is training regularly, and is able to compete on a national and, possibly, international level.

[Functional disorders and functional diseases in the region of the upper cervical spine particularly regarding the cervical joints. Current status and clinical relevance]. / Funktionelle Störungen und funktionelle Erkrankungen im Bereich der oberen Halswirbelsäule unter besonderer Berücksichtigung der Kopfgelenke. Aktueller Stand und klinische Relevanz.

Functional disorders of the upper cervical spine may be responsible for or the primary cause of persistent complaints following an injury or illness. Functional disorders involving the cervical joints, especially C0/C1 and C1/2 but also the C2/3 junction are of particular clinical relevance. Range of motion assessment is extremely important for the diagnosis of joint disorders. Hypomobility or "blockade" can be diagnosed using special examination techniques that, in many cases, can be extended for direct manual therapy. Periarticular structures involved in these dysfunctional processes, especially muscles and fasciae, must also be examined and treated. Clinical manifestations may include locally restricted muscle extensibility (e.g., trigger points, tension or muscle shortening) with zones of radiating pain as well as referred problems distal to the primary lesion. Functional disorders in the region of the upper cervical spine may be accompanied by various types of reflexive compensatory problems. Although they must be diagnosed separately, these disorders frequently respond to the manual therapy techniques used to treat the underlying functional problem. Even if the exact correlations to functional medicine cannot be scientifically demonstrated in every case, functional assessment and treatment techniques are, in our view, a useful addition to the armamentarium for orthopedic diagnosis and treatment.

Late recovery following spinal cord injury. Case report and review of the literature.

The authors of this prospective, single-case study evaluated the potential for functional recovery from chronic spinal cord injury (SCI). The patient was motor complete with minimal and transient sensory perception in the left hemibody. His condition was classified as C-2 American Spinal Injury Association (ASIA) Grade A and he had experienced no substantial recovery in the first 5 years after traumatic SCI. Clinical experience and evidence from the scientific literature suggest that further recovery would not take place. When the study began in 1999, the patient was tetraplegic and unable to breathe without assisted ventilation; his condition classification persisted as C-2 ASIA Grade A. Magnetic resonance imaging revealed severe injury at the C-2 level that had left a central fluid-filled cyst surrounded by a narrow donutlike rim of white matter. Five years after the injury a program known as "activity-based recovery" was instituted. The hypothesis was that patterned neural activity might stimulate the central nervous system to become more functional, as it does during development. Over a 3-year period (5-8 years after injury), the patient's condition improved from ASIA Grade A to ASIA Grade C, an improvement of two ASIA grades. Motor scores improved from 0/100 to 20/100, and sensory scores rose from 5-7/112 to 58-77/112. Using electromyography, the authors documented voluntary control over important muscle groups, including the right hemidiaphragm (C3-5), extensor carpi radialis (C-6), and vastus medialis (L2-4). Reversal of osteoporosis and an increase in muscle mass was associated with this recovery. Moreover, spasticity decreased, the incidence of medical complications fell dramatically, and the incidence of infections and use of antibiotic medications was reduced by over 90%. These improvements occurred despite the fact that less than 25 mm2 of tissue (approximately 25%) of the outer cord (presumably white matter) had survived at the injury level. The primary novelty of this report is the demonstration that substantial recovery of function (two ASIA grades) is possible in a patient with severe C-2 ASIA Grade A injury, long after the initial SCI. Less severely injured (lower injury level, clinically incomplete lesions) individuals might achieve even more meaningful recovery. The role of patterned neural activity in regeneration and recovery of function after SCI therefore appears a fruitful area for future investigation.

[Mental activity hand orthosis control using the EEG: a case study]. / Mentale Handorthesensteuerung über das EEG: Eine Fallstudie.

A report is given on the realization of a steering mechanism of a hand orthosis for a patient with paraplegia. An EEG-based Brain-Computer Interface (BCI) was used here for the first time, transferring purely mental activity to a control signal. This means that the patient has the capability to open or close the hand orthosis only by imagination of a movement. At this time, after a training period of about four months, the patient is able to move the hand orthosis with a certainty of almost hundred percent. The restored grasp function was verified by a grasp function test. Results are compared to those obtained using a conventional EMG-controlled orthosis.

Lower extremity applications of functional neuromuscular stimulation.

Functional electrical stimulation (FES) applications in the lower extremity are common in research laboratories, but clinical applications are minimal. This review summarizes current knowledge with respect to clinical application. When electrical stimulation is used in clinical applications for functional movement such as standing and walking, it is typically applied in an open-loop manner; a predetermined stimulus pattern is delivered regardless of the consequences of the actual movement. Few clinical applications of FES involve closed-loop control because of the numerous difficulties involved in its application. As with any volitional muscle contraction, electrically stimulated muscle contractions will exhibit fatigue. Although the dynamics of fatigue may differ, electrically stimulated muscle contractions cannot be continuously sustained, and if the duty cycle is too severe, even alternating periods of rest and contraction cannot be sustained at a constant force level. The exact nature of fatigue is highly specific to the past history of the individual muscle and to the individual subject. Despite their intricate detail, quantitative modeling studies have not yet been applied extensively to clinical applications. Present implantable systems are not yet a viable option for clinical application. It is not clear whether more success with surface or percutaneous systems must first be achieved to justify implantation or whether greater improvements in implantable technology and surgical protocols are needed before implantable systems will become practical. It is clear that almost any reasonably designed stimulation protocol will increase muscle bulk. The existence of other therapeutic benefits and their cost/benefit ratios remain to be fully established. It is possible to stand through bilateral stimulation of the quadriceps. Using surface electrodes, this technique is achievable in any physical therapy clinic having minimal expertise in neuromuscular stimulation. FES-aided standing must be conducted as a research project with a protocol approved by the local institutional review board, as there are currently no FDA-approved stimulation devices for standing. Multichannel FES systems are not currently available for clinical application in the United States. This may change if the "Parastep" system receives FDA approval. Percutaneous and implanted systems are years away from commercialization and clinical availability. Hybrid systems, based primarily on the reciprocating gait orthosis (RGO), are presently the only clinically available form of walking that includes some form of FES assistance. The costs and benefits of adding FES to the RGO and the long-term user acceptance rate for these systems remain to be determined.

Back school for patients with vertebral fractures.

Back school is behavior training for the prevention and treatment of back problems arising from faulty body posture and muscular dysfunction. This paper describes the conception and evaluation of a back school program for patients with vertebral fractures. The curriculum includes the provision of detailed information as well as physiotherapy, training in the right way to perform activities of everyday life, counseling, relaxation training, and self-monitoring. From October 1987 to June 1990 214 patients with vertebral fractures completed the back school program. The effectiveness of the program was measured by a knowledge test and a behavior test. The results suggest that this back school is an effective addition to conventional concept using physiotherapy exclusively.
