Clinical significance of the heterotopic ossification after total hip arthroplasty.

Heterotopic ossification represents one of the most frequent complications following any type of hip arthroplasty. However, disagreement exists regarding the clinical significance of heterotopic ossification after total hip arthroplasty (THA). This study evaluated the effect of different grades of heterotopic ossification on range of hip motion, pain, and the clinical outcome in patients after THA. The study included 198 patients with primary THA because of unilateral hip osteoarthritis, followed for a minimum of 1 year after THA. Diagnosis and classification of heterotopic ossification according to Brooker was achieved on anteroposterior radiograph of the hips 1 year postoperatively. The clinical outcome was assessed at 1-year follow-up with the use of the Harris hip score. Pain was assessed as the pain component of the Harris hip score. Hip range of motion was measured passively in the lying position with a goniometer and recorded in degrees according to the method suggested by the American Academy of Orthopaedic Surgeons 1988. The incidence of heterotopic ossification was 47% and the incidence of severe ossification was 11%. The severe heterotopic ossification significantly reduced clinical outcome, overall range of hip motion and certain components such as flexion, abduction and external rotation, but had no significant effect on pain, while the lower degree of ossification did not significantly influence the clinical outcome, hip motion and pain. This study has shown that only severe heterotopic ossification is of clinical significance.

Evaluation of low level laser and interferential current in the therapy of complex regional pain syndrome by infrared thermographic camera

UNLABELLED BACKGROUND/AIM; Complex regional pain syndrom type I (CRPS I) is characterised by continuous regional pain, disproportional according to duration and intensity and to the sort of trauma or other lesion it was caused by. The aim of the study was to evaluate and compare, by using thermovison, the effects of low level laser therapy and therapy with interferential current in treatment of CRPS I. METHODS The prospective randomized controlled clinical study included 45 patients with unilateral CRPS 1, after a fracture of the distal end of the radius, of the tibia and/or the fibula, treated in the Clinical Centre in Nis from 2004 to 2007. The group A consisted of 20 patients treated by low level laser therapy and kinesy-therapy, while the patients in the group B (n = 25) were treated by interferential current and kinesy-therapy. The regions of interest were filmed by a thermovision camera on both sides, before and after the 20 therapeutic procedures had been applied. Afterwards, the quantitative analysis and the comparing of thermograms taken before and after the applied therapy were performed. RESULTS There was statistically significant decrease of the mean maximum temperature difference between the injured and the contralateral extremity after the therapy in comparison to the status before the therapy, with the patients of the group A (p < 0.001) as well as those of the group B (p < 0.001). The decrease was statistically significantly higher in the group A than in the group B (p < 0.05). CONCLUSIONS By the use of the infrared thermovision we showed that in the treatment of CRPS I both physical medicine methods were effective, but the effectiveness of laser therapy was statistically significantly higher compared to that of the interferential current therapy.

Assessment of general movements and heart rate variability in prediction of neurodevelopmental outcome in preterm infants

BACKGROUND Adverse neurologic outcome in preterm infants could be associated with abnormal heart rate (HR) characteristics as well as with abnormal general movements (GMs) in the 1st month of life. AIMS To demonstrate to what extent GMs assessment can predict neurological outcome in preterm infants in our clinical setting; and to assess the clinical usefulness of time-domain indices of heart rate variability (HRV) in improving predictive value of poor repertoire (PR) GMs in writhing period. STUDY DESIGN Qualitative assessment of GMs at 1 and 3 months corrected age; 24h electrocardiography (ECG) recordings and analyzing HRV at 1 month corrected age. SUBJECTS Seventy nine premature infants at risk of neurodevelopmental impairments were included prospectively. OUTCOME MEASURES Neurodevelopmental outcome was assessed at the age of 2 years corrected. Children were classified as having normal neurodevelopmental status, minor neurologic dysfunction (MND), or cerebral palsy (CP). RESULTS We found that GMs in writhing period (1 month corrected age) predicted CP at 2 years with sensitivity of 100%, and specificity of 72.1%. Our results demonstrated the excellent predictive value of cramped synchronized (CS) GMs, but not of PR pattern. Analyzing separately a group of infants with PR GMs we found significantly lower values of HRV parameters in infants who later developed CP or MND vs. infants with PR GMs who had normal outcome. CONCLUSIONS The quality of GMs was predictive for neurodevelopmental outcome at 2 years. Prediction of PR GMs was significantly enhanced with analyzing HRV parameters.

Are Interferential Electrical Stimulation and Diaphragmatic Breathing Exercises Beneficial in Children With Bladder and Bowel Dysfunction

OBJECTIVE To evaluate the effects of interferential current (IC) stimulation and diaphragmatic breathing exercises (DBEs) in children with bladder and bowel dysfunction. PATIENTS AND METHODS Seventy-nine children with dysfunctional voiding and chronic constipation who were failures of primary care interventions were included in the prospective clinical study. All the children were checked for their medical history regarding lower urinary tract symptoms and bowel habits. Physical examination, including abdominal and anorectal digital examination, was performed. Children kept a bladder and bowel diary, and underwent urinalyses and urine culture, ultrasound examination of bladder and kidneys, and uroflowmetry with pelvic floor electromyography. Eligible children were divided into 3 groups (A, B, and C). All groups were assigned education and behavioral modifications. Additionally, group A underwent DBEs and IC stimulation, whereas group B received only DBEs. The treatment was conducted for 2 weeks in the clinic in all 3 groups,. The behavioral modifications and DBEs were continued at home for 1 month. Clinical manifestations, uroflowmetry parameters, and postvoided residual urine were analyzed before and after 6 weeks of therapy. RESULTS After the treatment, significant improvement in defecation frequency and fecal incontinence was noticed only in group A (P < .001 and P < .05, respectively). These children demonstrated significant improvement in lower urinary tract symptoms and postvoided residual urine (P < .001 and P < .05, respectively). Bell-shaped uroflowmetry curve was observed in 73.3% of group A patients (P < .001). CONCLUSION IC stimulation and DBEs are beneficial in chronically constipated dysfunctional voiders. Further trials are needed to define the long-term effects of this program.

Scintigraphy evaluation of the types of functional constipation in children with bowel bladder dysfunction

PURPOSE To evaluate the types of constipation according to colonic transit time in chronically constipated children with dysfunctional voiding (bowel bladder dysfunction, BBD group) and to compare the results with transit type in children with chronic functional constipation without urinary symptoms (constipation group) and children with normal bowel habits, but with lower urinary tract symptoms (control group). PATIENTS AND METHODS One-hundred and one children were included and their medical histories were obtained. The BBD group kept a voiding diary, and underwent urinalyses and urine culture, ultrasound examination of bladder and kidneys and uroflowmetry with pelvic floor electromyography. Radionuclear transit scintigraphy was performed in all children according to a standardized protocol. Patients were categorized as having either slow-transit (ST), functional fecal retention (FFR) or normal transit. RESULTS FFR was diagnosed in 31 out of 38 children with BBD, and 34 out of 43 children in the constipation group. ST was found in seven children with BBD, compared with nine children in the constipation group. The control group children demonstrated normal colonic transit. Urgency, daily urinary incontinence and nocturnal enuresis were noted only in children with FFR. Both children with ST constipation and FFR complained of difficulties during voiding, voiding postponement and urinary tract infections. CONCLUSIONS FFR is the most common form of constipation in children with dysfunctional voiding. However, some children might suffer from ST constipation. Differentiation between these two types of constipation is clinically significant because they require different treatment. Future studies with larger numbers of patients are needed to confirm the noted differences in urological symptoms in these two groups of constipated children..

The Effects of Preoperative Physical Therapy in Total Hip Replacement Surgery

METHODS Prospective clinical study included 36 patients 37-72 years old, assigned for unilateral THR due to end-stage hip osteoarthritis. Patients were randomized to a 4-week physical therapy program or education (control group) prior to surgery. After intervention all patients received rehabilitation regimen that included kinesy and occupational therapy, low frequency pulse magnetic fi eld (20 mT, 50 Hz) and interferent electrotherapy (1-100 Hz), for another 4 weeks. The WOMAC (Western Ontario and McMaster Universities) Index of Osteoarthritis and the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) were used for assessing outcomes a month before surgery, just prior to surgery and 6 months after. Range of motion in the affected hip and pelvifemoral muscle strength were measured, too.

The effectiveness of group Otago exercise program on physical function in nursing home residents older than 65 years: A randomized controlled trial

AIM To examine whether the 6-months group-based Otago exercise program is more effective than usual care on physical function and functional independence in nursing home residents older than 65 years. METHODS An observer-blind randomized controlled study included 77 independently walking, cognitively unimpaired residents aged 78.4±7.6years, of which 66.2% were female. Physical function was assessed at baseline, after 3 and 6months of the Otago exercise program by three performance tests: Berg Balance Scale (BBS), Timed Up and Go (TUG) and Chair Rising Test (CRT), and functional independence by the motor Functional Independence Measure (mFIM). RESULTS Significant within participant effects of time in EG for BBS, TUG and CRT (p<0.001) and for mFIM (p=0.010) were found. Between participant effects of groups on BBS, TUG, CRT and mFIM values were not significant. Changes in values of performed three tests regarding physical function were significantly different in EG and CG (p<0.001), as well as for functional independence test (mFIM) (p=0.019). In EG the values got better, while in CG values worsened. Effect sizes of change in the EG were higher for BBS, TUG and CRT compared to mFIM. CONCLUSION The Otago exercise program was shown as effective in improving balance, functional mobility, lower limbs muscle strength and functional independence, indicating that it could help in slowing of disability progression.

TOTAL HIP REPLACEMENT REHABILITATION: RESULTS AND DILEMMAS

The number of candidates for total hip replacement (THR) is steadily increasing. Judging by the clinical results and implant longevity, THR is one of the most common and most successful orthopedic interventions of all times. Material, design, surgical techniques and subsequent rehabilitation continue to evolve. Choice of the prosthesis and fixation technique depends on the patients’ bone structure and joint stability and their individual characteristics, such as age, weight and level of activity. Rehabilitation after THR is as important as the surgery. Rehabilitation protocols vary with the type of endoprosthesis. There is some controversial evidence about the differences in the surgical approach, the role of the preoperative education and exercises, as well as the implementation of the most efficient rehabilitation protocol. Despite many uncertainties and dilemmas, most studies have shown that majority of patients are satisfied with their arthroplasty results. Acta Medica Medianae 2018;57(1):48-53.

Correlation of thermal deficit with clinical parameters and functional status in patients with unilateral lumbosacral radiculopathy.

INTRODUCTION Lumbosacral radiculopathy is a pathological process that refers to the dysfunction of one or more spinal nerve roots in the lumbosacral region of the spine. Some studies have shown that infrared thermography can estimate the severity of the clinical manifestation of unilateral lumbosacral radiculopathy. This study aimed to examine the correlation of the regional thermal deficit of the affected lower extremity with pain intensity, mobility of the lumbar spine, and functional status in patients with unilateral lumbosacral radiculopathy. METHODS This cross-sectional study was conducted at the Clinic for Physical Medicine and Rehabilitation of the Clinical Center Niš, Serbia. A total of 69 patients with unilateral lumbosacral radiculopathy of discogenic origin were recruited, with the following clinical parameters evaluated: (1) pain intensity by using a visual analogue scale, separately at rest and during active movement; (2) mobility of the lumbar spine by Schober test and the fingertip-to-floor test; and (3) functional status by the Oswestry Disability Index. Temperature differences between the symmetrical regions of the lower extremities were detected by infrared thermography. A quantitative analysis of thermograms determined the regions of interest with maximum thermal deficit. Correlation of maximum thermal deficit with each tested parameter was then determined. RESULTS A significant and strong positive correlation was found between the regional thermal deficit and pain intensity at rest, as well as pain during active movements (rVAS - rest=0.887, rVAS - activity=0.890; P<0.001). The regional thermal deficit significantly and strongly correlated with the Oswestry Disability Index score and limited mobility of the lumbar spine (P<0.001). CONCLUSIONS In patients with unilateral lumbosacral radiculopathy, the values of regional thermal deficit of the affected lower extremity are correlated with pain intensity, mobility of the lumbar spine, and functional status of the patient.
