Long-term effects of heart transplantation: the gap between physical performance and emotional well-being

The purpose of our study was to assess physical and emotional factors in heart transplant patients. A prospective design was used to compare patients' physical symptoms, emotional complaints, and restrictions at admission to the waiting list, immediately after, and 1 and 5 years after heart transplantation. Thirty-three patients were included (30 male, 3 female) in the study. Their mean age at admission was 48 +/- 10.2 years. Of these, 23 suffered from cardiomyopathy, 8 from coronary heart disease, and 2 from valvular insufficiency. At admission, the patients suffered from symptoms of cardiac insufficiency, and were restricted in sports, gardening, hobbies, sexual life, job, food-intake, and mobility. More than three-fourths rated their physical and emotional status as moderate to poor. Emotionally, they suffered from irritability, restlessness, depression, psychic lability, lowered drive, lack of social contact, low self-esteem, and anxiety. At the end of rehabilitation (4-8 weeks after the operation), all physical and emotional complaints, as well as restrictions had significantly decreased (p < 0.0001 to p < 0.001), except for trembling, numbness of hands/feet, and food-intake. One year postoperatively, patients reported even fewer physical complaints (p < 0.01). Three-fourths rated their physical and emotional status good or excellent. Five years postoperatively--in contrast to physical status, restrictions, and physical complaints--the emotional complaints had increased significantly (p < 0.0001). Patients reported excellent physical performance up to 5 years postoperatively. On the other hand, the study revealed that their emotional well-being had significantly deteriorated from 1 to 5 years postoperatively. Attention should, therefore, not only be paid to the good physical health of the survivors, but also to the worsening of their emotional status.

Effect of detraining on bone and muscle tissue in subjects with chronic spinal cord injury after a period of electrically-stimulated cycling: a small cohort study

OBJECTIVE: To investigate adaptive changes in bone and muscle parameters in the paralysed limbs after detraining or reduced functional electrical stimulation (FES) induced cycling following high-volume FES-cycling in chronic spinal cord injury. SUBJECTS: Five subjects with motor-sensory complete spinal cord injury (age 38.6 years, lesion duration 11.4 years) were included. Four subjects stopped FES-cycling completely after the training phase whereas one continued reduced FES-cycling (2-3 times/week, for 30 min). METHODS: Bone and muscle parameters were assessed in the legs using peripheral quantitative computed tomography at 6 and 12 months after cessation of high-volume FES-cycling. RESULTS: Gains achieved in the distal femur by high-volume FES-cycling were partly maintained at one year of detraining: 73.0% in trabecular bone mineral density, 63.8% in total bone mineral density, 59.4% in bone mineral content and 22.1% in muscle cross-sectional area in the thigh. The subject who continued reduced FES-cycling maintained 96.2% and 95.0% of the previous gain in total and trabecular bone mineral density, and 98.5% in muscle cross-sectional area. CONCLUSION: Bone and muscle benefits achieved by one year of high-volume FES-cycling are partly preserved after 12 months of detraining, whereas reduced cycling maintains bone and muscle mass gained. This suggests that high-volume FES-cycling has clinical relevance for at least one year after detraining.

A análise com SRM mostrou responsividade baixa nos intervalos de avaliação de 3 meses (0,29; 0,38; 0,18 e 0,19), baixa a moderada em intervalos de 6 meses (0,59 e 0,51, 0,36), moderada em 9 meses (0,74 e 0,70) e alta em 1 ano (0,89). Atividade de descer escada: O ES apresentou responsividade baixa nos intervalos de avaliação de 3 meses (0,16; 0,25; 0,09; 0,08) e 6 meses (0,48; 0,35; 0,18), baixa a moderada em 9 meses (0,59, 0,44) e moderada em 1 ano (0,71). Análise com SRM mostrou responsividade baixa nos intervalos de 3 meses (0,25; 0,35; 0,12 e 0,09) e 6 meses (0,47; 0,38 e 0,21), moderada a baixa em 9 meses (0,62, 0,49) e moderada em 1 ano (0,74). Conclusão: A avaliação da atividade de subir escada, por meio da FES-DMD-D3, deve ser realizada em intervalos a partir de 9 meses, pois a responsividade é de moderada a alta. A avaliação do descer escadas deve ser realizada anualmente, pois houve responsividade moderada somente a partir de 12 meses

A simulation of the surface EMG for analysis of muscle activity during whole body vibratory stimulation

Many studies have accounted for whole body vibration effects in the fields of exercise physiology, sport and rehabilitation medicine. Generally, surface EMG is utilized to assess muscular activity during the treatment; however, large motion artifacts appear superimposed to the raw signal, making sEMG recording not suitable before any artifact filtering. Sharp notch filters, centered at vibration frequency and at its superior harmonics, have been used in previous studies, to remove the artifacts. [6, 10] However, to get rid of those artifacts some true EMG signal is lost. The purpose of this study was to reproduce the effect of motor-unit synchronization on a simulated surface EMG during vibratory stimulation. In addition, authors mean to evaluate the EMG power percentage in those bands in which are also typically located motion artifact components. Model characteristics were defined to take into account two main aspect: the muscle MUs discharge behavior and the triggering effects that appear during local vibratory stimulation. [7] Inter-pulse-interval, was characterized by a polimodal distribution related to the MU discharge frequency (IPI 55-80ms, σ=12ms) and to the correlation with the vibration period within the range of ±2 ms due to vibration stimulus. [1, 7] The signals were simulated using different stimulation frequencies from 30 to 70 Hz. The percentage of the total simulated EMG power within narrow bands centered at the stimulation frequency and its superior harmonics (± 1 Hz) resulted on average about 8% (± 2.85) of the total EMG power. However, the artifact in those bands may contain more than 40% of the total power of the total signal. [6] Our preliminary results suggest that the analysis of the muscular activity of muscle based on raw sEMG recordings and RMS evaluation, if not processed during vibratory stimulation may lead to a serious overestimation of muscular response.

Mobility and satisfaction with lower-limb prostheses and orthoses among users in Sierra Leone: A cross-sectional study

Objectives: To investigate patients' mobility and satisfaction with their lower-limb prosthetic or orthotic device and related service delivery in Sierra Leone; to compare groups of patients regarding type and level of assistive device, gender, area of residence, income; and to identify factors associated with satisfaction with the assistive device and service. Methods: A total of 139 patients answered questionnaires, including the Quebec User Evaluation of Satisfaction with Assistive Technology questionnaire (QUEST 2.0). Results: Eighty-six percent of assistive devices were in use, but half needed repair. Thirty-three percent of patients reported pain when using their assistive device. Patients had difficulties or could not walk at all on: uneven ground (65%); hills (75%); and stairs (66%). Patients were quite satisfied with their assistive device and the service (mean 3.7 out of 5 in QUEST), but reported 886 problems. Approximately half of the patients could not access services. In relation to mobility and service delivery, women, orthotic patients and patients using above-knee assistive devices had the poorest results. The general condition of the assistive device and patients' ability to walk on uneven ground were associated with satisfaction with the assistive devices and service. Conclusion: Patients reported high levels of mobility while using their device although they experienced pain and difficulties walking on challenging surfaces. Limitations in the effectiveness of assistive devices and limited access to follow-up services and repairs were issues desired to be addressed.

Impact on hip fracture mortality after the establishment of an orthogeriatric care program in a colombian hospital

El objetivo del estudio es evaluar la mortalidad a un año en pacientes con fractura de cadera, mayores de 65 años tratados en un programa establecido de orto-geriatría. 298 se trataron de acuerdo al protocolo de orto-geriatría, se calculo la mortalidad a un año, se establecieron los predictores de mortalidad orto-geriátrico. La sobrevida anual se incremento de 80% a 89% (p = .039) durante los cuatro años de seguimiento del programa y disminuyo el riesgo de mortalidad anual postoperatorio (Hazard Ratio = 0.54, p = .049). La enfermedad cardiaca y la edad maor a 85 años fueron predictores positivos para mortalidad.

Propiedades psicométricas de los instrumentos para la medición de la actividad física en adultos con discapacidad física relacionada con lesión de médula espinal: una revisión sistemática

Objetivo: Evaluar las propiedades psicométricas de los instrumentos para la medición de la actividad física en adultos de 18-65 años con discapacidad física por lesión de médula espinal. Materiales y métodos: Revisión sistemática. Las bases de datos de Medline, Scopus, Web of Science y 19 revistas especializadas fueron consultadas durante once días entre abril de 2015 y febrero de 2016 para identificar estudios originales de validación, sin límite de tiempo y que estuvieran publicados en español, francés y/o inglés. La calidad metodológica de los instrumentos de medición se evaluó usando las diferentes cajas de propiedades de la lista COSMIN. Resultados: Se identificaron 9229 referencias, de las cuales sólo 12 cumplieron los criterios de inclusión, dando como resultado 13 instrumentos de medición. Se evaluaron seis propiedades psicométricas. La propiedad más común fue la confiabilidad, además se observó que la calidad metodológica de los estudios incluidos no representa los resultados de las propiedades psicométricas de los instrumentos de medición. La calidad metodológica de los instrumentos para la evaluación de la actividad física en población con lesión medular espinal es “baja” para propiedades como consistencia interna, error de medición, sensibilidad, validez de criterio (con excepción del WISCI II que tiene buena validez) y excelente para validez de contenido y fiabilidad. Conclusión: Se ha encontrado que instrumentos empleados hasta el presente en la medición de la actividad física en población con discapacidad física relacionada con lesión de médula espinal han sido creados para otros tipos de discapacidad y otros instrumentos deben ser validados en futuros estudios.
