[Evaluation of the Chêneau brace in adolescent idiopathic scoliosis].

OBJECTIVE: We aimed to evaluate the Chêneau brace in the orthopedic treatment of adolescent idiopathic scoliosis to better determine the indications under which it could be prescribed. MATERIALS AND METHODS: This was a retrospective study including 63 patients treated by Chêneau brace for adolescent idiopathic scoliosis between 1997 and 2006. The Cobb angles of the curves in the frontal and sagittal planes as well as rotations and rib hump were measured at the beginning of treatment, with the brace, at the end of treatment and 2 years after discontinuing the brace. A variation of+/-10 degrees in angle was selected to judge the results. RESULTS: At the end of the treatment, 25.4% of the curves were improved and 60.3% stabilized, with 14.3% aggravated; 5 patients (7.9%) required surgery. At 2 years, the reduction in angle was 1.8 degrees, on average. The best results were obtained for the lumbar and dorsolumbar curves. A significant improvement was noted for the dorsal curves; the major double curves are not as accessible to the treatment. For curves whose initial angle was less than 30 degrees , an initial reduction of higher than 50% with the brace presented the best improvement at the end of the follow-up. We note a significant reduction of the rib hump but not accompanied by a reduction of rotation. Finally, we note a deleterious effect in the sagittal curves, with a slight flatness of the spinal profile. CONCLUSION: The continuous wearing of the Chêneau brace can stabilize the evolution of adolescent idiopathic scoliosis, apart from the forms with major double curves, which are not as accessible to the treatment. However, the improvement comes at the price of a slight flatness of the curves of the spine in the sagittal plane. The loss of the correction after discontinuing the brace is minor. We emphasize, therefore, the necessity to monitor the sagittal aspect of the spine as well as the possibility of early treatment, strict surveillance and prolonged follow-up.

[Transition in health care from youth to adulthood for disabled people].

Most children born with a chronic health condition or disability are expected to live more than 20 years. Health care is provided for these children in paediatric units until they are 18 years old, and the transition to the adult health care system is difficult because of poor collaboration between specialists and families who sometimes wonder if the adult specialist will be competent, although young disabled people need specialised follow-up. This report discusses U.S. and English models in the transition in health care. Coordination between paediatricians and adult services is necessary. The neuromuscular disorders clinic is cited as an example.

Kinematic analysis of handbike propulsion in various gear ratios: implications for joint pain.

BACKGROUND: Though considered more efficient and less constraining than the hand-rim wheelchair, the handbike has rarely been studied especially as regards its kinematic parameters. The hypothesis of this investigation is that the range of upper extremity motions are risk factors for joint pain during handbiking as is the case during hand-rim wheelchair propulsion. This paper aims to study handbike propulsion in maximal sprint conditions in order to determine potential risk factors for joint pain. METHODS: Eight able-bodied participants with no experience in handbike propulsion performed three sprints of 8 s each using three gear ratios in a handbike mounted on a home-trainer. The mean velocity per arm cycle, the cycle frequency, the angular parameters for the upper extremities were calculated, as well as the corresponding angular accelerations, with the help of a 3D movement analysis. FINDINGS: An increase in gear ratio (22/21, 32/21, and 44/21) significantly increases the maximal velocity, the flexion/extension of the trunk, as well as the adduction/abduction of the elbow, while it reduces the frequency of movements and the flexion/extension angular accelerations of the shoulder and the elbow. Regardless of what gear ratio is used, maximal angular amplitudes of the upper extremities are comparable to the values obtained with a hand-rim wheelchair. Interpretation. The high amplitudes and fast angular joint accelerations of the upper extremity found in this study are near or superior to the ergonomic recommendations generally advised. These considerations could be taken into account to prevent overuse injuries.

[Parkinson gait analysis using in-shoe plantar pressure measurements].

INTRODUCTION: The literature reports some studies describing the walking pattern of patients with Parkinson's disease, its deterioration with disease severity and the effects of various treatments. Other studies concerned the plantar pressure distribution when walking. The aim of this study was to validate the use of baropodometric measurements for gait analysis of parkinsonian patients at various stages of disease severity and in on and off phases. METHODS: Fifteen normal control subjects and fifteen parkinsonian patients equipped with a plantar pressure measurement system performed walking tests. The parkinsonian patients performed the walking tests in off phase then in on phase. A clinical examination was performed to score the motor handicap on the UPDRS scale. RESULTS: Analysis of the plantar pressures of the parkinsonian subjects under various footprint areas detected significant baropodometric differences compared with controls, between groups with different UPDRS scores, and before and after L-Dopa treatment. CONCLUSIONS: Plantar pressures measurements allow a sufficiently fine discrimination for using it to detect parkinsonism and monitor patients with Parkinson's disease.

Identification of healthy elderly fallers and non-fallers by gait analysis under dual-task conditions.

OBJECTIVE: We compared falling and non-falling healthy elderly subjects to identify balance disorders associated with falling. Gait parameters were determined when carrying out single and dual tasks. DESIGN: Case comparison study. SETTING: Subjects were studied in the gait laboratory at Hôpital Roger Salengro, Lille, France. SUBJECTS: A group of 40 healthy elderly women were assigned to one of two groups according to their falling history: 21 fallers aged 70.4 +/- 6.4 years and 19 non-fallers aged 67.0 +/- 4.8 years. All subjects performed first a single leg balance test with two conditions (eyes open/closed). Then, gait parameters were analysed under single-task and dual motor-task conditions (walking with a glass of water in the hand). MAIN MEASURES: Falls, number of times suspended foot touched the floor during the single leg balance test, cadence, speed, stride time, step time, single-support time, stride length and step length during walking under single- and dual-task conditions. RESULTS: During the single leg balance test, fallers placed their feet on the floor three times more often than non-fallers under eyes open conditions (P < 0.05) and twice as often under eyes closed conditions (P < 0.05). In the single-task condition, no significant difference in gait parameters was reported between fallers and non-fallers. There was a significant difference (P < 0.05) in the gait parameters (cadence, speed, stride and step time, single-support time) between fallers and non-fallers under dual-task conditions. CONCLUSIONS: Dual tasks perturb walking in fallers, who exhibit deteriorated static balance. Consequently, walking under dual-task conditions plus a single leg balance test could be helpful in detecting walking disorders and planning physiotherapy to prevent falls.

[Leather corset for the treatment of camptocormia: 31 cases].

INTRODUCTION: Camptocormia is an acquired postural disease leading to wide-ranging emerging rachidian kyphosis. Kyphosis can be observed when the patient stands up, walks or sits. The functional impact can be significant. When the etiology is better known, personalized treatments are often deceitful. Physical therapy and orthesis may be proposed. Classical antikyphotic orthesis for the trunk are usually not well tolerated and are quickly abandoned. We proposed the use of traditional leather orthesis for such cases. MATERIALS AND METHOD: This retrospective study undertaken between April 2001 and April 2003 included 31 patients with camptocormia for whom orthesis was indicated. Eight patients benefited from use of a classical lumbar belt. All assessed the ortheses as not satisfactory. In 27 patients, leather orthesis was prescribed, and 20 used it, 19 of whom answered a questionnaire assessing functional benefits as follows: the patient is well or very well straightened, suffers less from trunk pain, suffers less or no longer when standing up without assistance during a long period, has less or no difficulty to walk, feels less or no longer tired because of the effort to stay straight without the orthesis, does not resent the alteration of social life because of the orthesis, and assesses active life as satisfactory. RESULTS: The average time to wear the othesis was 33 months. Sixty-eight percent of patients wore it at least 9 hours a day; 84% were able to put it on by themselves. The respiratory and cutaneous consequences were judged good and digestive and urinary tolerance adequate. With the orthesis, 74% of the patients responded positively to 5 of the 7 functional areas assessed. Why patients do not wear ortheses is often explained by the failure to obtain a satisfactory straight position and/or an ankle flexion, associated significant pathology, lack of motivation and difficulty in putting the orthesis on alone.

[Treatment of ejaculation disorders by midodrine (Gutron) per os. Retrospective study of about 16 subjects].

PURPOSE: We evaluate the efficiency and side effects of midodrine in the treatment of sperm transport disturbances. MATERIALS AND METHODS: This retrospective study concerned patients addressed in Andrologia Department between 1995 and 2002 for treatment of sperm transport disturbances by administration of Midodrine per os (from 2.5 to 20 mg). Anterograde and retrogrades ejaculates (in urine sample) were examined. RESULTS: Sixteen patients (middle age of 36 years) were included: 12 neurologic lesions (central or peripheral, with 3 diabetes), four post-surgical (urologic and digestive) ejaculatory incompetence. One patient obtained anterior and retrograde ejaculation, two patients obtained anterior ejaculation and six retrograde ejaculations by midodrine per os. This treatment was inefficient in eight subjects. Side effects were exceptional. DISCUSSION: We obtained anterior or retrograde ejaculation in half of our population. The success was more important in patients with central neurologic injuries, diabetes or post-surgical troubles. In peripheral neurologic injuries, midodrine per os (maximal dose of 20 mg) was ineffective. CONCLUSION: Our study demonstrates the efficiency and good tolerance of midodrine per os for treatment of sperm transport disturbances.

[Cognitive disorders and falls: experience of the Lille multidisciplinary falls service].

BACKGROUND: Falls and dementia are two major public health problems which concern the elderly population. Cognitive impairment, as a result of Alzheimer's disease or non-Alzheimer dementia, is recognized as a risk factor for falling. Through the experience of the Multidisciplinary Falls Consultation, our aims were first, to evaluate the prevalence of a cognitive decline among outpatients who consult for falls, and second, to determine whether the cognitive impairment was known and diagnosed before the consultation or not. METHODS: Data concerning the first 300 outpatients who completed the initial evaluation are reported. Each patient was assessed by a geriatrician, a neurologist, and a physiatrist, who visited him or her at home. Cognitive impairment was defined as a Mini-Mental State Examination (MMSE) score<24. RESULTS: Of the 300 patients, 228 patients completed the initial evaluation. Among them, 97 (42.5 percent) had a MMSE score<24; 55 had mild stage dementia (MMSE score between 23 and 18) and 42 were at a moderate or severe stage (MMSE score< or =17/30). The cognitive decline was not diagnosed before the consultation in 80 of the 97 patients (82 percent). CONCLUSION: The findings show that a large proportion of old persons presenting with gait disturbance at the Multidisciplinary Falls Consultation have an underlying cognitive decline. Assessment of cognitive functions is required in every elderly faller.

[Impact of functional restoration programs on fears, avoidance and beliefs in chronic low back pain patients].

OBJECTIVE: To assess the impact of functional restoration programs on fears, avoidance and beliefs in chronic low back pain. METHODS: Open prospective study in eight spine centers. Seventy patients enrolled in several restoration programs were evaluated before and at the end of the program. Variables recorded were pain (VAS), disability (Quebec back pain disability scale), handicap (VAS), anxiety and depression (HAD scale), and fears, avoidance and beliefs (FABQ). RESULTS: All variables recorded significantly improved at the end of the programs except for fears about professional activities (FABQ1) and lumbar mobility. Fears about physical activities (FABQ2) significantly decreased after these programs. Variations in FABQ1 and FABQ2 scores were not correlated with variations in scores of outcome measures assessing impairment, disability, and handicap. CONCLUSION: Functional restoration programs in their current form in France do not decrease fears and beliefs about professional activities in chronic low back pain patients. Adding psychosocial intervention at the work place to the functional restoration programs may lead to a better impact on fears about work thus reducing work loss.

Improved kinematics of unrestrained arm raising in C5-C6 tetraplegic subjects after deltoid-to-triceps transfer.

STUDY DESIGN: Prospective comparative study. OBJECTIVE: To determine whether control of upper limb joint synergy during unrestrained arm raising involving shoulder and elbow flexion is modified by deltoid-to-triceps transfer. SETTING: Rehabilitation unit for spinal cord injury patients, France. METHODS: Five C6 subjects with C5-C6 tetraplegia sustained posterior deltoid-to-triceps transfer and were compared to a control group of 11 subjects. Kinematics of shoulder and elbow joints before, 6 month and 1 year after surgery, during straight-arm raising (SAR) in the plane of the scapula and hand-to-nape-of-neck movements (HNNMs) were explored. Motion was recorded with a six-camera Vicon motion analysis system and the data used to assess the coupling of elbow and shoulder flexion velocities (EFVs and SFVs) and extension velocities. RESULTS: All subjects were initially assessed at 6.9 months (mean) postsurgery. Three of the upper limbs were assessed a second time (mean 17.9 months). The first assessment showed an increase in shoulder flexion amplitudes in tetraplegic subjects with presurgery shoulder flexion deficits. Peak SFVs and EFVs and extension velocities were slightly modified at the first postsurgery assessment and dramatically improved at the second assessment during both SAR and HNNM. Despite these increased velocities, joint coordination was only partially restored. CONCLUSION: A restored elbow active extension improves the speed of elbow flexion. The additional improvement of shoulder motion emphasises the relation between joints in the control of arm movement.

[Asymmetries in dynamic plantar pressure distribution measurement in able-bodied gait: application to the study of the gait asymmetries in children with hemiplegic cerebral palsy].

OBJECTIVES: The aim of this study was to analyse, firstly, the plantar pressure distribution in healthy subjects in order to validate or invalidate the previous studies results on the asymmetrical profile of the stance phase. The studies of asymmetries was based on the identification of a propulsive foot and a loading foot from a concept introduced by Viel. Secondly, the approach was applied to the study of gait asymmetries in two children with hemiplegic cerebral plasy. MATERIAL AND METHOD: Thirty healthy control subjects and two hemiplegic children (H1 and H2) performed a walking test at self selected speed. The recordings of dynamic parameters were realized thanks to an in-shoe plantar pressure analysis system (Parotec, by Paromed Medizintechnik, GMBH, Germany). The pressure peaks were determined from the recording of pressures under eight footprint locations. A program calculated the sum of forces under the heel and determined the loading foot. By defect, the second foot is the propulsive foot. RESULTS: The asymmetrical profile of the human normal stance phase was validated. Under the heel, the pressure peaks lower by 28 % were noticed beneath the loading foot compared to the propulsive foot. Inversely, under the metatarsal heads and the hallux, the pressure peaks were greater by 32 % beneath the propulsive foot. For the two hemiplegic children, the plantar pressure profile equally highlighted significant differences between the unaffected and affected feet. The pressure peaks under the affected heel were respectively lower by 21 % and 97 % for H1 and H2. The loading function was found and associated to the affected limb. The propulsive function was not systematically found under the unaffected foot. DISCUSSION: The analysis of plantar pressure measurements during able-bodied gait showed differences between the two lower limbs. These dynamic asymmetries are the results of a natural functional organization of the supports differentiating a loading foot and a propulsive foot and corroborating the concept proposed by Viel. The hemiplegic gait also presented dynamic asymmetries partially agreement with a personalized functional logic of loading and propulsion. However, the asymmetrical profile can also result a gait self-optimization strategy compensating biomechanical, anatomical and physiological disorders linked to the cerebral deficiency.

[Outcome and quality of life after three years in a cohort of patients with severe traumatic brain injury].

OBJECTIVES: The late outcome of patients with severe traumatic brain injury (STBI) has been investigated by measuring deficits, disability and social handicap, but their quality of life (QOL) has been less evaluated, and not by a direct analysis of the subjective patient "and relatives" QOL. The aim of this study was to investigate this outcome and the QOL, with its predictive factors, 3 years after STBI, in a homogeneous cohort of patients. MATERIAL AND METHODS: We selected all adult patients from the Lille area (north of France) admitted in the CHU in 1995 following STBI. Each was evaluated at home, in the presence of a close relative, using the EBIS document. This one investigates the medical history, initial status and late outcome, as well as the subjective QOL of patients (evaluated by the patient and by a close relative: 0-10 on an analogical visual scale) and close relatives. Relationships between possible explanatory factors and QOL were analysed using correlation tests. RESULTS: Among the 33 patients, 23 survived at three years. The mean initial GCS score was of 5,6/15 and the mean coma duration of 18.5 days. At three years, physical deficits were usually discrete, intellectual deficits more important and the emotional and behavioural problems even more severe. The GOS was of 6 in one patient, 4-5 in seven, 2-3 in seven and 0-1 in eight. Dependence in advanced activities was more sever than in elementary activities. The subjective QOL of patients was discretely lower (m = 5,48/10) than that estimated by close relatives (m = 5,91). The relatives QOL was similarly reduced (m = 5,45). The factors most influencing the patients QOL were the cognitive and behavioural problems and the dependence in the advanced activities and the GOS for the patients QOL, and the behavioural problem and the dependence in advanced activities for the relatives QOL. CONCLUSION: The reduction of the patients "and relatives" QOL was parallel at three years. Emotional and behavioural problem as well as the dependence in advanced activities mainly explained these QOL.

[Reliability of global interdigital pinch (vice pinch) dynamometral values measured by Microfet 2].

OBJECTIVE: To study test-retest reliability of pinch grip strength with a two-month gap in three upper limb positions. To study factors causing variability of peak force. MATERIAL AND METHODS: Forty healthy control volunteers, sex-ratio 1, mean age 36.6 years (sd = 9.9), were separated into four groups of ten persons. The Microfet 2 dynamometer was used to measure peak force developed during pinch grip. The measurements were made in three positions: upper limb parallel to body, arm flexed at 90 degrees and during the Roos manoeuvre. Test-retest reliability was evaluated after two months. Statistical analysis used the correlation test (p = 0.05). RESULTS: Reliability proved to be excellent in all three positions and in all four groups. Dynamometer values were stable between the beginning and end of the Roos manoeuvre in this healthy population. There were no significant differences between peak force measured in the three positions and between left and right upper limbs. DISCUSSION: The Roos manoeuvre gives a stable and reliable result in a population without thoracic outlet syndrome. Dynamometer tests are also reliable in the usual upper limb positions, in accordance with other studies. CONCLUSION: This dynamometric test should be useful in assessing the severity of thoracic outlet syndrome and in demonstrating the therapeutic efficacy of different treatments.

Benefits of home visits for falls and autonomy in the elderly: a randomized trial study.

OBJECTIVE: To investigate whether home visits by a occupational therapist reduces the risk of falling and improves the autonomy of older patients hospitalized for falling. DESIGN: In this randomized, controlled trial set in a geriatric hospital, 60 patients (mean age, 83.5 yr) who were hospitalized for falling were recruited from the acute medicine department. A home visit from an occupational therapist and an ergotherapist assessed patients' homes for environmental hazards and recommended modifications. The outcomes measured were falls, autonomy, hospitalization for falling, institutionalization, and death. RESULTS: During the follow-up period, the rate of falls, hospitalization for falls, institutionalization, and death were not significantly different between the two groups. Both groups had a loss of dependence at 12 mo. This loss of dependence was significant in the control group but not in the intervention group. CONCLUSIONS: Home visits from occupational therapists during hospitalization of older patients at risk for falling can help to preserve the patient's autonomy.

Visual deficiency and scoliosis.

STUDY DESIGN: A transversal study involving group comparison was performed. OBJECTIVE: To investigate whether children who are visually impaired have a higher rate of spinal deformity. SUMMARY OF BACKGROUND DATA: Evidence has accumulated pointing to an association between idiopathic scoliosis and postural control in which vision is involved. An association between scoliosis and ocular troubles is present in many diseases, but no study on a large blind population has yet been undertaken. METHODS: Data was obtained from an official school screening campaign involving two consecutive classes in a regional school for the visually handicapped and from two consecutive classes in three public vocational schools. This study included 75 children who were visually handicapped (mean age, 11 years and 7 months) and 728 healthy control participants (mean age, 10 years 2 months). Trunk deformity was assessed by Moire topography and measurement of any trunk hump by the forward bending test. The children with visual impairment who had evidence of trunk deformity underwent radiographs of the spine a few months after the back surface assessment, then again 12 to 24 months later. RESULTS: Occurrences of trunk deformity were significantly different in the two groups (P < 0.0001), with five times more back surface abnormalities in the blind population. Of the 26 children with both visual impairment and trunk deformity, 18 had a structural scoliosis on radiographs, with an average Cobb Meyer angle of 14.1 degrees (range, 10-28 degrees ), but there was evidence of an evolving condition in only three cases. CONCLUSIONS: These findings are compatible with a postural etiology of scoliosis in the visually impaired population.

Successes and setbacks of the falls consultation: report on the first 150 patients.

OBJECTIVE: We report the results of a Falls Consultation. DESIGN: Data concerning the first 150 patients are reported. Each patient was assessed by a geriatrician, a neurologist, and a physiatrist, who visited him or her at home, and was reassessed by the same geriatrician 6 mo later. RESULTS: Of the 150 patients, 135 patients completed the initial evaluation. Most of them were frequent fallers. The population was very heterogeneous regarding the health status and the degree of disability. In most cases, falls were the result of several interacting factors. The most frequent recommendations from the staff were physical therapy, environmental changes, and medication changes. Over the following 6 mo, approximately one out of four patients had experienced new falls. However, the risk of falling was significantly reduced (5.3 +/- 7.3 falls in 6 mo before vs. 0.8 +/- 1.6 falls in 6 mo after the intervention). The Activities of Daily Living score was a predictor of recurrent falls, hospitalization, and institutionalization. CONCLUSION: Our results show that a multidisciplinary falls consultation can be efficient in reducing the risk of falls in nonselected elderly fallers but suggest that differential strategies are needed to manage adequately the more vigorous and the frail old person as well.

Long-term assessment of a sanitary education and lumbar rehabilitation program for health care workers with chronic low back pain at the University Hospital of Lille.

A back school was established in 1992 at the University Hospital of Lille (France) for employees with low back pain. We report its medical and socioeconomic benefits with a mean time to follow-up of 4 years. Our retrospective study included 108 health care workers and provides objective data (absenteeism, use of health care) and subjective information (progression of pain and disorder, social and professional impact) before training and a mean of 4 years after training. We found that 92% of the participants were satisfied with the training and that back pain had regressed or resolved for 55% of them. Both the frequency and duration of pain had decreased significantly. Seventy percent continue to apply the advice they received in their everyday life. Dealing with the problems specific to professional activities contributed to reduce the strain experienced on the job by the health care workers and improved their satisfaction at work. Global absenteeism was reduced by 57.8%, whereas it was reduced by 33% for back pain alone 4 years after implementing this program. Our study provides evidence of the positive impact of this type of training on the way back pain is perceived and on everyday life. The assessment of the cost/efficiency ratio completes the list of durable benefits reported here.

[Tridimensional gait analysis after unilateral subtalar arthrodesis].

PURPOSE OF THE STUDY: Subtalar arthrodesis can be useful in various conditions. Initially used for the treatment of congenital or acquired foot deformities, it was later applied to surgical repair of traumatic injury. The subtalar joint does however play an important role in gait, particularly for transmitting rotational movement of the leg to the foot. The functional outcome after subtalar arthrodesis has been the object of many studies. These studies examined clinical and radiological results and raised the problem of determining the appropriate extent of the fusion. None of these studies has however provided a three-dimensional analysis of gait after subtalar arthrodesis, performed in the present work. MATERIAL AND METHODS: We used the Vicon VX3D system with 2 integrated force platforms. Acquisition was made at 50 Hz. The Vicon recording was coupled with EMG recordings of the gastrocnemius, the rectus, the anterior tibialis, and the glutius medius. Gait was analyzed in 8 patients who had undergone unilateral subtalar arthrodesis at least 18 months earlier. Several recordings were made for each patient but only one complete gait cycle was retained for analysis of kinematic, kinetic and electromyographic curves and ground reaction forces. Wilcoxon's test for paired series was used to compare the operated side to the healthy side (excepting EMG recordings). RESULTS: The operated and healthy side were significantly different. Total amplitude of joint movement was lower for the operated side: 16.5 degrees versus 21.5 degrees for the healthy side. Peak power generated at the ankle for plantar flexion was lower at the end of the stance phase. Electromyography recordings showed a shift in muscle activity between the healthy and fused foot. DISCUSSION: Few statistical differences were found between the tested values. It can thus be concluded that gait pattern is globally symmetrical after subtalar arthrodesis and that this fusion has little functional impact on the knee or the hip. The difference in amplitude between the healthy and operated side showed a wider variability than observed by Winter in the healthy subject that was also greater than the measurement error reported by Laasel. We did not perform a statistical analysis of the EMG data since the values recorded were arbitrary and the observed shift in activities had no general impact. CONCLUSION: Despite the reduction in flexion-extension amplitude of the ankle, subtalar arthrodesis allows a globally symmetrical gait in the experimental conditions described.
