Validity, reliability, and bias between instrumented pedals and loadsol insoles during stationary cycling.

The purpose of this study was to evaluate the validity and reliability of the loadsol in measuring pedal reaction force (PRF) during stationary cycling as well as lower limb symmetry. Ten healthy participants performed bouts of cycling at 1kg, 2kg, and 3kg workloads (conditions) on a cycle ergometer. The ergometer was fitted with instrumented pedals and participants wore loadsol plantar pressure insoles.

Effects of different slopes on hip and ankle biomechanics of replaced and non-replaced limbs of patients with total knee arthroplasty during incline ramp walking.

Although knee biomechanics has been examined, hip and ankle biomechanics in incline ramp walking has not been explored for patients with total knee arthroplasty (TKA). The purpose of this study was to investigate the hip and ankle joint kinematic and kinetic biomechanics of different incline slopes for replaced limbs and non-replaced limbs in individuals with TKA compared to healthy controls. Twenty-five patients with TKR and ten healthy controls performed walking trials on four slope conditions of level (0°), 5°, 10° and 15° on a customized instrumented ramp system.

Examination of Curcumin and Fenugreek Soluble Fiber Supplementation on Submaximal and Maximal Aerobic Performance Indices.

Unlabelled: This study examined the effects of curcumin and fenugreek soluble fiber supplementation on the ventilatory threshold (VT) and peak oxygen consumption ( V ˙ O peak).

Methods: Forty-five untrained men and women were randomly assigned to one of three supplementation groups: placebo (PLA, = 13), 500 mg·day CurQfen (CUR, = 14), or 300 mg·day fenugreek soluble fiber (FEN, = 18). Participants completed a maximal graded exercise test on a cycle ergometer to determine the VT and V ˙ O peak before (PRE) and after (POST) 28 days of daily supplementation.

Escin/diethylammonium salicylate/heparin combination gels for the topical treatment of acute impact injuries: a randomised, double blind, placebo controlled, multicentre study.

Objectives: To investigate the clinical efficacy and safety of escin-containing gels in the topical treatment of blunt impact injuries.

Methods: Competitors in soccer, handball, or karate competitions were enrolled within two hours of sustaining a strain, sprain, or contusion and treated three times with the trial gel within a period of eight hours. Patients were randomised to three parallel groups consisting of two active treatment gels, containing escin (1% or 2%), 5% diethylammonium salicylate, and 5000 IU heparin, or placebo gel.

Magma storage beneath Axial volcano on the Juan de Fuca mid-ocean ridge.

Axial volcano, which is located near the intersection of the Juan de Fuca ridge and the Cobb-Eickelberg seamount chain beneath the northeast Pacific Ocean, is a locus of volcanic activity thought to be associated with the Cobb hotspot. The volcano rises 700 metres above the ridge, has substantial rift zones extending about 50 kilometres to the north and south, and has erupted as recently as 1998 (ref. 2).

[Sports as a health risk for the locomotor system].

The analysis of sport injuries commonly takes into account well known external and internal risk factors. This brief review is dealing with some general risks related to emotional and cognitive aspects. It is emphasized that such risks play a major role in developing prevention strategies.

[Typical sports injuries, sports specific risks and comparison with other sources of accidents].

In the discussion of limiting the growth of medical spending there are intentions to exclude the costs of sport injuries from coverage by the public health insurance system. The aim of this study is to analyse typical sport injuries and to compare them with injuries from other fields of accidents and thus to deliver arguments in the discussion of costs in public health system.

Recurrent dislocation of the patella and the Goldthwait operation.

In this study 17 patients with recurrent dislocation of the patella were followed up 10 years after their Goldthwait operation. The subjective and clinical findings were excellent or good in 70%. X-radiographs indicated osteoarthritis of the femoropatellar joint in 60%.

[Densitometric studies of the tensile strength of the proximal femur].

The prognostic assessment of the fracture resistance of the proximal femur is of great importance to the age related increasing incidence of femur neck fractures. This is particularly important in sport for the elderly. The statistical relationship between the osteodensitometrically determined bone density and the risk of a femur neck fracture has been shown in epidemiological studies, whereby the determination of bone density at the proximal femur has provided the most precise predictive results.

Influence of joint stability on the results of arthroscopic subacromial decompression.

We performed arthroscopic subacromial decompression on 70 patients. Each of them had either type I or type II impingement according to Neer. Sixty-five patients were then observed for a postoperative period of three years.

[Bone density measurements of the proximal femur in relation to torsion of the femoral neck].

The DEXA-method allows for bone mineral density measurements of different regions of the skeletal system. It is known that results obtained from the spine with this two-dimensional method may be biased in cases of spondylosis, spondylarthritis, and compression fractures; similarly biased results can be expected at the proximal femur due to morphometric peculiarities. The influence of anteversion and rotation of the femoral neck has been investigated in the present study.

[5-10-year results with the straight-shaft Müller prosthesis].

103 patients with 106 Müller straight stem prostheses could be evaluated clinically and radiologically after an average follow-up period of 6.8 years (range 5 to 10 ys.).

[Results of histological studies of the flexor tendon sheath in 35 flexor tenosynovectomies in carpal tunnel syndrome].

This paper presents the results of histologic studies conducted in the context of tenosynovectomy of the flexor tendons to treat carpal tunnel syndrome. The most common findings were inflammatory changes of the synovial sheath, vascular pathology and fibrous changes of the connective tissue.

[Total i.v. anesthesia with S-(+)-ketamine in orthopedic geriatric surgery. Endocrine stress reaction, hemodynamics and recovery].

Unlabelled: Clinically-used ketamine is a racemic mixture of two isomers, S-(+)- and R-(-)-ketamine. Previous investigations showed the anaesthetic potency of S(+)-ketamine to be three times higher than that of R-(-)-ketamine. It was the aim of this study to compare the effects of S-(+)-ketamine and racemic ketamine on endocrine and cardiovascular parameters, recovery, and side effects in geriatric patients during total intravenous anaesthesia (TIVA) for orthopaedic surgery.

[Results of studies of surgically treated carpal tunnel syndrome with obligate tenosynovectomy of the flexor tendons].

The authors present a follow-up of thirty five patients with carpal tunnel syndrome, who had undergone surgical treatment including synovialectomy of the flexor tendons. Beyond the clinical findings, pre- and postoperative comparison of the electromyograms, conduction velocities and an exact analysis of the lipid disorders were studied. These findings and the results of the histological analysis of the tenosynovial membrane are evaluated with special regard to the etiology of the carpal tunnel syndrome.

Range of motion after total condylar knee arthroplasty.

In this study the function of the knee measured at a medium-follow-up of 5-6 years was correlated with influencing factors concerning the implant of total condylar knee prosthesis in 90 patients. The only variable affecting postoperative extension was the preoperative range of extension whereas postoperative flexion was influenced by the preoperative flexion, valgus deviation of the preoperative AP tibial-femoral angle, position of the patella, and thickness of the resection of the distal femur cut.

[Habitual patella dislocation and Goldthwait's surgery].

In this study 17 patients with recurrent dislocation of the patella were followed up 10 years after Goldthwait-operation. The subjective and clinical findings were excellent rsp. good in 70%, whereas the x-ray findings showed osteoarthritis of the femoropatellar joint in 60%.

[Transverse skeletal axes of the lower extremity in coxarthrosis].

Femoral anteversion, anteversion of the acetabulum and tibial torsion of 47 patients with idiopathic osteoarthritis of the hip were determined by computerized tomography. From all these parameters only the anteversion of the acetabulum showed differing values in hips with and without osteoarthritis. There was a considerable range at the individual measured values in all parameters and differences between the male and female groups could be found in femoral anteversion and anteversion of the acetabulum.

[Calcareous tendinitis--special forms of the upper extremities. Clinical aspects and differential diagnosis].

Calcifying tendinitis of the shoulder joint is a relatively common condition. Its pathogenesis is well documented in anatomical-pathological terms. The clinical observation of four unusual locations in the upper limb makes us to suspect the same pathological process as in the supraspinatus location.

[Postoperative dislocation as an early complication of total hip endoprosthesis].

Basing on 13 dislocations of 215 total hip arthroplasties are presented the characteristics of this complication. All things considered the dislocation following total hip arthroplasty seems to be no serious complication, if there is no severe operation failure and if the necessary treatment consisting in plastic cast immobilisation is performed.

[Results of follow-up of untreated anterior cruciate ligament rupture].

A series of 90 patients, 85 males and 5 females, all with ACL-ruptures had a follow up between 5 and 12 years. All of them had a primary arthrotomy with or without meniscectomy but in no case an operative repair of the ACL-rupture was done. The most concomitant injury was a torn medial meniscus in 76.
