The aim was to evaluate the effect of a biofeedback electrogoniometer in the control of recurvation of the knee while walking in patients with neurological diseases. Eighteen patients were trained daily for 12. 8 sessions on average with an electrogoniometer attached to the knee, which gave a signal at a threshold value of 180 degrees in order to avoid hypertension of the knee. The improvement was ...

Knee extensor performance, in 17 subjects with chronic anterior cruciate ligament (ACL) tear, was investigated preoperatively and on four different occasions postoperatively, using isokinetic measurements and electromyography of single maximum and repetitive manoeuvres. Preoperatively maximum mechanical output was comparatively low (injured leg), deteriorating further by 50% at fourteen weeks post ...

In isokinetic dynamometry of the knee extensors the influence of gravity on the lower limb is often neglected. The aim of this study was to assess the shape, the quantity and reproducibility of the gravity correction curve (GCC). Eight amputees participated in this study. The GCC was produced on an isokinetic dynamometer (QD) throughout the range of motion on the amputated side with prosthesis and ...

The effect of electro-motor stimulation (EMS) upon the increase in power production of the tibialis anterior muscle (TA) of healthy individuals in both the maximally stretched (ST group) and shortened (SH group) positions was investigated. The effect of cross-education upon the contralateral muscle was also examined. EMS with a frequency of 50 hertz, a duration of 0. 2 miliseconds, and a rectangul ...

A general population of 928 men and women aged 30, 40, 50 and 60 years participated in a health survey with emphasis on low back trouble (LBT). In all 135 variables were analysed to identify possible indicators for first-time experience and recurrence or persistence of LBT during a one-year follow-up. Stepwise logistic regression analyses were carried out to identify the most informative combinati ...

For 137 patients who sustained a femoral neck fracture domiciliary circumstances, ADL functional level and walking ability were recorded during a period of six months in 1983. At the time of injury 71% were living at home or in a so-called service apartment with medical and domestic facilities, and 28% in chronic care institutions (1% were transferred from other acute care units). Of the surviving ...

Bone metabolism has been assessed in 36 hemiplegic patients (18-77 years), 26 with CVA and 10 with head injuries. The results show an increase of serum calcium and phosphorous levels in the first month as well as hydroxyprolinuria. The radiological examination showed signs of demineralisation, as well as single photon absorptiometry of both arms. Bone scan by 99Te demonstrated a hypercaptation in ...
