Beneficial effects of chronic low-frequency stimulation of thigh muscles in patients with advanced chronic heart failure.

AIMS: Patients with chronic heart failure (CHF) exhibit detrimental changes in skeletal muscle that contribute to their impaired physical performance. This study investigates the possibility of counteracting these changes by chronic low-frequency electrical stimulation (CLFS) of left and right thigh muscles. METHODS AND RESULTS: (mean+/-SD) 32 CHF patients (53+/-10 years) with an LVEF of 22+/-5%, NYHA II-IV, undergoing optimized drug therapy, were randomized in a CLFS group (CLFSG) or a control group (controls). The groups differed in terms of the intensity of stimulation, which elicited strong muscle contractions only in the CLFSG, whereas the controls received current input up to the sensory threshold without muscle contractions. Functional capacity was assessed by peak VO(2), work capacity, and a 6-min-walk (6-MW). Muscle biopsies were analyzed for myosin heavy chain (MHC) isoforms, citrate synthase (CS) and glyceraldehydephosphate dehydrogenase (GAPDH) activities. Peak VO(2)(mlmin(-1)kg -1) increased from 9.6+/-3.5 to 11.6+/-2.8 (P<0.001) in the CLFSG, and decreased from 10.6+/-2.8 to 9.4+/-3.2 (P<0.05) in the controls. The increase in the CLFSG was paralleled by increases in maximal workload (P<0.05) and oxygen uptake at the anaerobic threshold (P<0.01). The corresponding values of the controls were unchanged, as also the 6-MW values, the MHC isoform distribution, and both CS and GAPDH activities. In the CLFSG, the 6-MW values increased (P<0.001), CS activity was elevated (P<0.05), GAPDH activity decreased (P<0.01), and the MHC isoforms were shifted in the slow direction with increases in MHCI at the expense of MHCIId/x (P<0.01). CONCLUSIONS: Our results suggest that CLFS is a suitable treatment to counteract detrimental changes in skeletal muscle and to increase exercise capacity in patients with severe CHF.

Long-term transcutaneous neuromuscular electrical stimulation in patients with bipolar sensing implantable cardioverter defibrillators: a pilot safety study.

Neuromuscular electrical stimulation (NMES) is an option for increasing thigh muscle strength and endurance capacity in patients with chronic heart failure. Electromagnetic interference (EMI) by the signals with sensing of implantable cardioverter defibrillators (ICDs) is possible. The aim of the present pilot safety study was to test the safety of a long-term NMES in patients with ICDs. Six patients with subpectoral ICDs were subjected to long-term NMES of thigh muscles. Four inpatients received NMES to increase muscle strength, and two outpatients performed NMES as a home treatment to increase endurance capacity. During long-term NMES, all patients together received 14 139 799 biphasic electrical pulses and 412 425 on-phases without adverse events. ICD function after the stimulation period revealed no abnormalities in any patient. These results indicate that long-term NMES of thigh muscles seems to be safe in patients with ICDs, providing that an individual risk is excluded before.

Safety of a combined strength and endurance training using neuromuscular electrical stimulation of thigh muscles in patients with heart failure and bipolar sensing cardiac pacemakers.

Neuromuscular electrical stimulation (NMES) is an effective and non-strenuous therapy to enhance the strength and endurance capacity of the skeletal muscles in patients with severe chronic heart failure. NMES in patients with pacemakers is controversial because potential electromagnetic interference may result in pacemaker malfunction. Therefore, such patients are in general excluded from NMES. The aim of this pilot study was to evaluate the safety of a combined NMES protocol to increase strength and endurance capacity of the skeletal muscles in patients with heart failure and implanted pacemakers. Seven patients with chronic heart failure and implanted cardiac pacemakers with bipolar sensing leads received NMES treatment of thigh muscles, using a combined protocol comprising biphasic, symmetric, rectangular constant current impulses at different frequencies (8-50 Hz), pulse width up to 60 s (8 Hz), 4 s (15 Hz), 4 s (30 Hz), and 6 s (50 Hz), and amplitudes up to +/- 100 mA (all frequencies) applied to both knee extensor and flexor muscles via surface electrodes (8 x 13 cm each). Acute electromagnetic interference during a safety procedure (telemetric monitoring) before therapeutic NMES application was not observed in any of the patients. The 7 patients received during 20 therapeutic NMES sessions a total of 23,380 on-phases, comprising 2194.08 x 10(3) biphasic electrical pulses, without adverse events. Heart rate monitoring during stimulation and pacemaker interrogation revealed no abnormalities. NMES treatment of thigh muscles using a combined NMES protocol to enhance strength and endurance capacity appears to be safe in patients with heart failure and implanted pacemakers with bipolar sensing, as far as the described electrode configuration and parameter range is applied.

Quality of life in patients with non-metastatic differentiated thyroid cancer under thyroxine supplementation therapy.

GOALS: When thyroid and other cancers are "cured" it is often assumed that the patients are able to resume their normal lives. This was a cross-sectional study to evaluate health-related quality of life (HRQOL) and to identify rehabilitation needs of patients with non-metastatic thyroid cancer under thyroxine supplementation therapy. PATIENTS AND METHODS: Included in the study were 150 consecutive patients with differentiated thyroid cancer (age 52 +/- 14 years, range 25-83 years; male/female 39/111). All patients had a history of total thyroidectomy followed by radioiodine ablation, were free of metastatic disease and under levothyroxine treatment. The mean period since the diagnosis of thyroid cancer was 5.5 +/- 6 years (range 0-23 years). Health-related quality of life was evaluated using the SF-36 Health Survey. The findings were compared with sex- and age-matched reference values. RESULTS: "Role-emotional" and "Vitality" were significantly lower ( P<0.001 and P<0.005, respectively) in the group as a whole ( n = 150). In the subgroup of patients with a recent (less than 1 year) diagnosis of thyroid cancer ( n = 51), however, the following subscales were significantly lower: "Mental Health" ( P<0.01), "Role-emotional" ( P<0.001), "Role-physical" ( P<0.005), "Social functioning" ( P<0.005) and "Vitality" ( P<0.001). Multiple regression analysis identified a significant positive correlation between "Mental Health", "Physical functioning", "Vitality", "Role-emotional" and "Social functioning" with the time since initial diagnosis, and there was also a positive correlation between "Physical functioning", "Bodily pain" and "Role-emotional" with male gender. CONCLUSIONS: These findings indicate that "Vitality", "Role-physical", "Mental Health", "Role-emotional" and "Social functioning" are significantly impaired during the first year after diagnosis. Thereafter, quality of life improves correlating with the time since initial diagnosis. However, "Vitality" and "Role-emotional" remain permanently impaired in thyroid cancer patients. A multidisciplinary rehabilitation concept should include psychological support and an early start to exercise to improve physical performance of these patients leading to better HRQOL and to help them fulfill their social role earlier.

Functional and biochemical properties of chronically stimulated human skeletal muscle.

The present study was undertaken to investigate in a randomized controlled trial the effects of chronic (10 weeks, 4 h per day, 7 days per week) low-frequency (15 Hz) stimulation (CLFS) of the knee extensor and hamstring muscles of both legs in healthy volunteers via surface electrodes. A control group (n=10) underwent the same treatment (sham stimulation) as the CLFS-treated group (n=10), except that stimulation intensity was kept at a level which did not evoke contractions. Biopsy samples were taken before the onset and after cessation of stimulation from the right vastus lateralis muscle of all subjects. The biopsy samples were analyzed for changes in myosin heavy chain (MHC) isoforms and activities of citrate synthase (CS) and glyceraldehyde phosphate dehydrogenase (GAPDH) as markers of aerobic-oxidative and anaerobic pathways of energy metabolism, respectively. In addition, functional properties, i.e., oxygen consumption (VO(2)) and work capacity, were assessed. Sham stimulation did not affect the functional properties and had no detectable effect on MHC isoform and enzyme activity patterns. Conversely, CLFS induced changes in the MHC isoform pattern in the fast-to-slow direction with an approximately 20% decrease in the relative concentration of MHCIId/x (from 28% to 22%) and an approximately 10% increase in the relative concentration of MHCI (from 30% to 34%). In addition, CLFS led to a approximately 9% increase in the activity of CS concomitant with an approximatley 7% decrease in the activity of GAPDH. This increase in aerobic-oxidative capacity was accompanied by improved work capacity and VO(2) at the anaerobic threshold by 26% and 20%, respectively.

Pathogenesis of bone loss in heart transplant candidates and recipients.

BACKGROUND: Heart transplantation (HTX) is associated with decreased bone mineral density and changes in bone metabolism. We conducted this study to evaluate the pathophysiology of bone metabolism in HTX candidates and recipients. METHODS: Thirty-six HTX recipients were compared with 36 HTX candidates concerning biochemical parameters of bone metabolism and bone mineral density. RESULTS: Osteocalcin, bone-specific alkaline phosphatase, cross-linked-N-telopeptide of type I collagen, estradiol, serum creatinine, and blood urea nitrogen concentrations were significantly higher, whereas the calcium-creatinine ratio, thyrotropin, thyroxine, and bone mineral density were significantly lower in HTX recipients than in HTX candidates. Compared with a control group, HTX candidates had decreased renal function and increased bone resorption, whereas HTX recipients additionally had increased alkaline phosphatase and osteocalcin levels. In HTX recipients, we found positive correlations between creatinine clearance and bone mineral density; daily and cumulative cortisone doses were not associated with bone mineral density. CONCLUSIONS: In HTX candidates, disturbances in bone metabolism with increased bone resorption may be caused partly by existing low-grade renal insufficiency, regular intake of loop diuretics, and restriction of mobility. In HTX recipients, immunosuppressive therapy-glucocorticoids and cyclosporine-seem to be responsible for changes in bone metabolism.

[Therapy of head injuries caused by animal slaughter guns].

Slaughterer's guns ("humane killers") are powder-activated cattle skull impacting tools. Today mechanical stunning is typical for country like regions, because in the municipal slaughter-houses electrical stunning of pigs and ruminants is preferred. In rare cases these weapons are used for suicide. They then cause penetrating brain lesions and if the victim survives the brain-damage, an encephalitis caused by the impacted material results. The neurosurgical treatment is to revise the gunshot canal and to remove impacted fragments of bone and contaminated skin (imprimat) under antibiotic cover. A psychiatric treatment of the mostly underlying depression and a rehabilitative treatment should complete therapy. So treatment of slaughterer's gun injury should have a multidisciplinary approach.

[Aerobic endurance training for cancer patients].

With the increase in the number of patients who survive cancer, there is a growing need to attend to the physical and emotional effects of cancer and oncological treatment. Reduced physical performance, fatigue, nausea, weight gain, psychological distress, changes in body image, dependency, and reduced quality of life are some of the short- and long-term sequelae of cancer. We describe data from the literature about firstly the effects of aerobic exercise as an additive treatment for cancer patients, and about the feasibility of aerobic exercise secondly during oncological treatment, and thirdly in patients suffering from terminal cancer. The data from the literature support that exercise as an additive treatment may help to attenuate the physical limitations caused by cancer and oncological treatment and there by contribute to rehabilitation and quality of life of cancer patients. Feasibility of aerobic exercise has been demonstrated also for patients suffering from advanced cancer. Aerobic exercise has been shown to provide benefits to cancer patients. It enables these patients to recover their physical function and to return to an active lifestyle. Aerobic exercise seems to be an effective possibility to reduce sequelae of cancer and to increase quality of life.

Aerobic exercise as additive palliative treatment for a patient with advanced hepatocellular cancer.

Aerobic exercise is known to improve biopsychosocial outcomes in cancer patients. Currently, exercise is not regarded as a quality-of-life intervention for patients with advanced cancer. The aim of this case study was to determine the feasibility and effects of an aerobic exercise programme for a patient with advanced hepatocellular cancer. After written informed consent, a 55-year-old male patient with advanced hepatocellular carcinoma participated in an aerobic exercise programme of precise intensity, duration and frequency, consisting of ergometer cycling 2 times a week, carried out for a period of 6 weeks. Exercise testing and a 6-min walk were performed, and the patient's quality of life was assessed. The feasibility, safety and beneficial effects of the programme were proven for this patient. At the end of the exercise programme, peak work capacity had increased by 20.3%. The patient has experienced an improvement in physical performance, which was underlined by the 6-min walk. Quality of life has been improved (physical functioning, vitality, mental health, role functioning/emotional, social functioning). Knowledge about the benefits of aerobic exercise for patients suffering from advanced cancer is not yet widespread. Nevertheless, aerobic exercise initiated and executed with appropriate care may serve as a useful additional means of palliative treatment in some patients with advanced cancer.

[Splints in occupational therapy of the hand in an Austrian central hospital--current status].

Ergotherapeutic splinting is essential in the treatment of diseases, injuries and innate deformities of the hand. However due to its high material and staff costs, a definitely diagnosed indication is a prequisite for prescription. A retrospective study was performed using the Krankenhausinformationssystem (KIS) to establish the total number of hand splints prescribed by the Department of Physical Medicine and Rehabilitation of the General Hospital of Vienna from 1/1992 until 8/1998, as well as referring doctors/departments and diagnoses leading to referral were recorded and descriptively evaluated. The total number of patients was 1972. 1236 (63%) of the cases were referred by surgical departments/branches, 410 (20%) by internal departments, 151 (8%) by the neurological department and 175 (9%) by other departments. The diagnosis leading to referral were rheumatoid arthropathies (542 = 26%), peripheral nerve lesions (458 = 22%), tendon lesions (201 = 10%), Dupuytren' contractures after surgery (184 = 8%), degenerative joint diseases (82 = 4%), conditions after fractures (55 = 2.5%), patients after amputations (50 = 2.3%), disorders of the central nervous system (53 = 2.5%), focus removals (40 = 2%) and tendovagintis (35 = 1.7%). The remaining 19% were referred due to surgical repositionings, soft tissue injuries, local infections and various other diagnoses. The majority of ergotherapeutic splintings was prescribed due to forms of rheumatic or rheumatoid diseases, peripheral nerve lesions as well as hand surgery. In this study documenting the clinical practice of a medical center was primarily aimed at providing the basis for further discussion of both factual and economic aspects of future developments in splinting.

Cancer rehabilitation: particularly with aspects on physical impairments.

Cancer can cause multiple impairments, activity limitations and participation restrictions. According to individual case findings and needs, rehabilitation treatment is varied. The review mainly focuses on specific problems. Because of functional deficits cancer patients suffer from persistent emotional and social distress and a reduced quality of life (QOL). QOL encompasses at least the four dimensions of physical, emotional, social and cognitive function, which may be positively influenced by physical exercise. Physical exercise also has been shown to prevent or minimise inactivity/ disuse problems and to reduce fatigue. The management of sexuality dysfunction has to begin with a thorough history taking and a consequent sexuality counselling. The goals of rehabilitation procedures under palliative care are not only to control physical pain but also to help with mental, social and spiritual pain, together with other symptoms. Rehabilitation problems in head and neck cancer, sexuality, lung cancer, prostate cancer, breast cancer and lymphedema can be improved by rehabilitation. The review mainly focuses on impairment and activity limitation. Social, psychological and vocational aspects are left aside in this review.

Factors that influence the duration of splint wear in peripheral nerve lesions.

OBJECTIVE: To assess the weekly frequency and overall duration of wear for splints used to treat peripheral nerve lesions and factors that possibly influence splint wear. DESIGN: A total of 78 patients (23 women, 55 men) who had been treated with a hand splint for peripheral nerve palsy were interviewed by telephone, based on a preformulated questionnaire. The duration of wear, reasons for terminating use, the effect of the splint, the patients' assessment of splint treatment, the patients' instruction, and the patients' level of education were recorded. Survival analysis for the entire period of wear and logistic regressions to determine factors that influence splint wear were performed. Comparison of effect scores between lesions in the dominant those in the nondominant hand were carried out with a test. RESULTS: The median duration of wear was 6 mo for daytime and 4 mo for nighttime splints. Daytime splints were worn by 85% and nighttime splints by 84% of patients for 5-7 days per week. The reported effect of the splint was the only significant factor that influenced the frequency of wear. The splint was reported to be significantly more effective in the dominant hand than in the nondominant hand. Numerically, radial nerve lesions and cock-up wrist splints were most common. CONCLUSION: Regular splint wear was registered in the majority of patients and was positively influenced by a good effect of the splint, which was reported to be better in the dominant hand.

Step aerobic vs. cycle ergometer training: effects on aerobic capacity, coordinative tasks, and pleasure in untrained adults--a randomized controlled trial.

The purpose of the study was to evaluate the impact of step aerobic (StA) and cycle ergometer training (CET) on physical performance, coordination, and pleasure, during workout. Forty untrained persons (40-70 years) were randomly assigned to either of the two regimens. Prior to and after three months of training, we investigated the participants' physical performance with a cycle ergometer test and by testing coordinative tasks (upper extremities: tapping test; lower extremities: one-leg stance). After the training period, visual analog scales were used to evaluate personal assessment (pleasure, wellbeing, team spirit, interest in prolongation of training). StA increased the relative oxygen uptake at the anaerobic threshold (RVO2AT) while CET increased the relative maximal oxygen uptake (RVO2max) to a statistically significant extent. However, intergroup comparison failed to show group-specific differences. Concerning coordinative tasks, the members of the StA group achieved a significant time reduction for both hands' tapping test. However, only the improvement in left-handed tapping was significantly higher than that achieved by members of the CET group. Despite the absence of group-specific differences, CET members showed a statistically significant change when comparing the duration of pre- with post-training time for one-leg stance under proprioceptive conditions. Team spirit was significantly higher in the StA group than in the CET group. Except for the time reduction in left-handed tapping, the present study found no group-specific differences in physical performance and coordination. Participating in a StA class has a more cohesive effect on the individual members than attending a CET group.

[Optimizing electrotherapy--a comparative study of 3 different currents].

Neuromuscular electrical stimulation can be used to increase strength of skeletal muscle. In neuromuscular electrical stimulation of innervated skeletal muscle, the application of the highest possible intensities of electricity is an important determinant of therapeutic success with regard to strength training. The therapeutic goal of "strengthening muscles" is opposed to the side effect of discomfort through the application of electricity. The aim of the present study was to compare three forms of electric current with respect to subjective tolerance and maximum achievable muscular strength. Twenty-nine healthy male volunteers were included in a single-blind study in which three forms of electric current were applied in a randomized fashion. The following types were compared: a short monophasic form, a biphasic form that was twice as long in terms of impulse duration, and a long monophasic form with an equal impulse duration than tht of the biphasic form and with an impulse form that corresponded to the short monophasic current. Stimulation was administered via surface electrodes placed on the knee extensors in the lower extremity on the right side. The intensity of the current was increased to the individual limit of tolerance or to a maximum of 100 mA. The main target parameter used to determine the success of treatment was the maximum electrically induced strength as a percentage of maximal voluntary contraction. The short monophasic form of electricity was associated with much less discomfort than the long monophasic and biphasic forms (p < 0.0001, p = 0.0062). Furthermore, the biphasic form was better tolerated (and therefore had a larger therapeutic range of application) than the long monophasic form (p = 0.041). The biphasic and long monophasic forms produced higher values for maximum electrically induced strength than did the short monophasic form (p = 0.0001, p = 0.0010). To summarize: the biphasic form had a larger range of therapeutic application than the long monophasic form. Furthermore, the biphasic form produced 40% more electrically induced strength than the short monophasic one. It may be concluded that, in terms of therapeutic application, the biphasic form of electric current is superior to the monophasic forms described in the present study.

Calcific trochanteric bursitis: resolution of calcifications and clinical remission with non-invasive treatment. A case report.

Calcific trochanteric bursitis, a common regional pain syndrome, is characterized by chronic, intermittent aching pain over the lateral aspect of the hip and limitation of function. Effective treatment is invasive, including infiltration therapy and surgical intervention. The therapeutic effects of conservative treatment modalities have not been proven. A 59-year-old woman presented at the department of physical medicine and rehabilitation with a 2-year history of pain in the right hip. She had been treated with several agents such as glucocorticoids and local anesthetics (via injection) for two years, but without success. Physical examination revealed the clinical diagnosis of bursitis trochanterica. Radiographic findings showed calcified rounded masses measuring about 1.5 cm in diameter around the greater trochanter; a calcific bursitis trochanterica was diagnosed. The patient presented for conservative treatment in order to avoid surgical intervention for removing the calcification and the bursal sac. A non-invasive treatment regimen including intensive pulsed ultrasound therapy, physiotherapy and iontophoresis was started. The conservative treatment led to a remission of both, symptoms as well as radiographic findings, which revealed complete resolution of calcifications. This case report shows that, in cases of calcific trochanteric bursitis (including those with extensive calcifications), a non-invasive conservative treatment regimen including intensive high-dosed pulsed ultrasound therapy should be attempted before more invasive treatment (injections, surgery) is considered.

Hypertrophic osteoarthropathy caused by PGE1 in a patient with congestive heart failure during cardiac rehabilitation.

Continuous chronic drug infusion with PGE1 via a portable pump and neuromuscular electrical stimulation (NMES) help to improve the quality of life in patients with severe chronic heart failure waiting for a donor heart, as both treatments can be performed at home. We report a 56-year-old woman suffering from severe chronic heart failure, who was referred for a cardiac rehabilitation program because of progressive muscle weakness and weight loss. Due to her underlying heart disease she was unable to perform voluntary exercise. NMES of both knee extensor muscles was started. Under simultaneous chronic drug infusion with PGE1 via a portable pump the patient developed clinical signs of hypertrophic osteoarthropathy, which prevented her from continuing the rehabilitation program. X-ray examinations and bone scans concurred with the diagnosis of secondary hypertrophic osteoarthropathy. After the PGE1 dose had been reduced, the clinical signs of the osteoarthropathy resolved and the patient was able to continue the rehabilitation program with no difficulty. This case report underlines the importance of being aware of the potential side effects of modern cardiac drugs in the complex treatment of patients waiting for a donor heart.

[Aerobic physical training in a breast cancer patient with inflammatory recurrence].

Aerobic exercise has positive effects on physical performance and illness-related quality of life of cancer patients. However reports of advanced cancer patients who exercise are rare in medical literature. A 38-year-old female patient suffering from breast cancer performed an aerobic exercise program during adjuvant chemotherapy (cycle ergometry, 3x/w). After the diagnosis of relapsed inflammatory breast cancer, oncological treatment was changed to radiation therapy to reduce tumour mass. The patient continued the exercise program until palliative mastectomy. Her compliance was excellent. Despite the underlying progressive disease, endurance performance improved substantially. These findings were supported by a subjective score (Grimby). Evaluation of quality of life (SF-36, EORTC-QLQ-C30) revealed improvements of emotional wellbeing, emotional role, vitality and physical functioning, but increasing pain. The patient reported benefit due to increased psychological, social and physical wellbeing. This case report demonstrates feasibility and benefits of aerobic exercise for a patient with advanced breast cancer undergoing palliative treatment.

[Postoperative rehabilitation of patients with carpal tunnel syndrome].

The purpose of this study was to investigate the effect of mobilisation or splinting on symptoms after surgical Treatment of Carpal Tunnel Syndrome. Only original articles concerning the effect of mobilisation or splinting on symptoms after surgical Treatment of Carpal Tunnel Syndrome were included in this investigation. Concerning these topics only seven original articles were found. There was no significant influence of splinting for several weeks found on the symptom "pain" in the literature. Even there was a delay of returning to activities of daily living and the recovery of fist und keypinch strength through splinting. A program of physiotherapy and ergotherapy lead to a significant shorter recovery of dexterity in comparison to an home exercise program. Even the rehabilitated patients showed a shorter return-to-work interval. After carpal tunnel surgery neither physiotherapy nor splinting lead to a significant release of the symptom "pain". But physiotherapy leads to a shorter recovery of dexterity and shorter return-to-work interval. Due to the lack of knowledge about this topic further controlled clinical studies investigating the rehabilitation process after carpal tunnel surgery would be necessary.
