RESUMO

The Askling's H-test is considered a useful return to play criterion after a hamstring muscle injury (HMI). However, it assesses only the active and passive flexibility of posterior thigh muscles. This may lead the practitioner to underestimate a compensation or abnormal movement pattern. The aim of this study was to analyze these kinematic aspects and their reliability, and evaluate the hamstring (HM) and gluteus maximus (GM) muscles' activities. Twelve healthy male volunteers were tested during two session of three trials for passive and active tests. Dynamic flexibility (97.2 ± 6.0°) was significantly greater than the passive one (70.5 ± 14.7°) (p < 0.001), and good intra-individual reproductibility for most kinematic characteristics was observed. Biceps Femoris long head, semitendinosus and GM mean activities (20.1 ± 11.2%; 14.3 ± 7.3% and 25.2 ± 22.1%, respectively) were found to be low to moderate, indicating that only a moderate level of activity occurred during the active H-test, in comparison to other movements such as sprinting itself. In addition, the activity of the posterior thigh muscles during the active H-test appeared to be variable among the volunteers. These findings suggest that the H-test should be interpreted on an individual basis rather than relying on general characteristics, and be considered as an intermediate tool before more strenuous activities such as returning to sprint. With this comprehensive approach, clinicians can gain a more accurate understanding of their patients' progress and make more informed decisions about their readiness to return to play.

RESUMO

Over the last decade, Physical and Rehabilitation Medicine (PRM) is a medical specialty that has evolved considerably in the various fields that concern it : from the management of low back pain and lumbosciatalgia or osteoporosis in a multidisciplinary manner, through the use of new technologies in neuro-locomotor rehabilitation and robotisation in amputee patients for example, the development of regenerative medicine and prevention in sports traumatology and, finally, the progress of electrophysiology techniques for the diagnosis of small-fibre neuropathies. These various advances will be discussed in this article.


Au cours de la dernière décennie, la Médecine Physique et Réadaptation (MPR) est une spécialité médicale qui a fortement évolué dans les différents domaines qui la concernent : de la prise en charge des lombalgies et lombosciatalgies ou encore de l'ostéoporose de manière pluridisciplinaire, en passant par l'utilisation des nouvelles technologies en rééducation neuro-locomotrice et de la robotisation en rééducation, chez les patients amputés par exemple, le développement de la médecine à vocation régénérative et la prévention en traumatologie du sport et, enfin, les progrès des techniques d'électrophysiologie pour le diagnostic des neuropathies à petites fibres. Ces différentes avancées seront abordées dans cet article.

RESUMO

BACKGROUND: Adequate motor control is considered important for spinal stability and the prevention of low back pain in adulthood and in childhood. OBJECTIVE: Given that the sitting position can affect proprioception, this study aimed to evaluate the influence of using at school a triangular and dynamic cushion on schoolchildren's trunk motor control. METHODS: Thirty 8-year-old schoolchildren were randomized into a control group (n= 15) and a "cushion group" (n= 15), in which the children used the cushion for one year and a half. At the end of this period, a 3D-analysis was used to assess lumbar spine proprioception by means of a trunk repositioning task performed blindfolded in a seated position in two conditions (on a stable and on an unstable surface). RESULTS: The schoolchildren in the cushion group performed better at the trunk repositioning task (p= 0.02) and hold their lumbar lordosis (p= 0.03) better than the control children, in both conditions (stable and unstable). CONCLUSIONS: This preliminary study suggests that daily use of a triangular dynamic cushion has a beneficial impact on children's lumbar proprioception. Further studies are needed to confirm these results and investigate the effectiveness of its use to prevent low back pain in adulthood.

RESUMO

BACKGROUND: Low back pain is highly prevalent in the general population and is even reported as early as at primary school. A poor sitting position has been suggested as an etiologic factor. This study analysed, in primary schoolchildren, the influence of a triangular dynamic cushion that aims to help children maintain their physiological lumbar lordosis and to induce movement to reduce the static effect of the sitting position. METHODS: Thirty 8-year-old children took part in this study. A 3D analysis combined with electromyography was used to evaluate the biomechanics and the related muscle activation in two sitting positions (with and without a triangular cushion on a horizontal stool) during a 15-minute working task. In addition, the force of the feet on the ground was assessed with a force plate. FINDINGS: The cushion improved the trunk-thighs angle, lumbar lordosis, anterior pelvis tilt, and feet support on the ground (p<0.0001). In addition, sitting on the cushion appeared to be more dynamic (p<0.05) and induced a decrease of the lumbar paravertebral muscle activity (p<0.01). INTERPRETATION: Sitting on a dynamic triangular cushion tends to favour the "ideal" siting position usually described in the literature and to decrease the level of paravertebral muscle recruitment. Seeing that sitting position is a risk factor to develop low back pain, the cushion could be a solution to prevent it.

RESUMO

OBJECTIVE: To investigate the relationship between frailty and sarcopenia, by evaluating the prevalence of sarcopenia among frail, pre-frail and robust elderly nursing home residents in Belgium. METHODS: This is an analysis of baseline data collected from the SENIOR (Sample of Elderly Nursing home Individuals: an Observational Research) cohort. All subjects received a sarcopenia evaluation, based on the definition proposed by the European Working Group on Sarcopenia in Older People (EWGSOP). The frailty evaluation was primarily based on FRIED's definition but also on 9 other operational definitions. RESULTS: A total of 662 subjects (73.1% of women) were included in this analysis (mean age: 83.2±8.99 years). The prevalence of sarcopenia was 38.1% whereas the prevalence of frail and pre-frail persons was respectively 24.7% and 61.4%. Among frail, pre-frail and robust subjects, respectively 47%, 38.9% and 16.3% were diagnosed sarcopenic. The prevalence of sarcopenia according to ten different operational definitions of frailty ranged between 32.8 % (i.e. Frail scale Status and Frailty Index) and 47% (i.e. Fried definition). CONCLUSION: This research highlights that over a third of nursing home residents are sarcopenic and the percentage is almost 50% among frail subjects; those latter constitute about 1 in 4 of the population of nursing home residents studied here.

RESUMO

OBJECTIVES: Adequate management of haemophilia patients requires early detection of joint impairment in relatively asymptomatic patients. This study sought to quantify the impact of the ankle's structural impairment on muscle strength in children, adolescent and young adults with haemophilia (CAAwH). METHODS: Twenty-three CAAwH underwent bilateral magnetic resonance imaging (MRI) assessing the anatomical status of tibiotalar joint (TTJ) and subtalar joint (STJ) using the International Prophylaxis Study Group MRI scale. An isokinetic dynamometer enabled a detailed evaluation of muscle strength at slow and fast speed. In parallel, 10 typically developing healthy boys (TDB) participated in a 1-week interval test-retest assessment to assess the test's reliability. RESULTS: Forty-six MRI ankle scores were obtained, with 11 patients unilaterally affected and one bilaterally. Of the 13 affected feet, nine showed abnormalities at TTJ, three at the posterior STJ and the remaining one at both joints. Muscle strength was not reduced in CAAwH exhibiting TTJ and/or STJ arthropathy, as compared to healthy TDB, nor was there any difference between the CAAwH's affected or unaffected sides. CONCLUSION: Contrarily to adult patients, CAAwH with repeated ankle bleeding may be less impaired than current structural evaluations imply, with possibly a latency between the occurrence of structural and functional damage.

RESUMO

BACKGROUNDS: The aim of this study was to assess the relationship between the level of ambulatory physical activity, measured by physical activity tracker, and the clinical components of physical frailty, among nursing home residents. METHODS: We proceeded in 3 steps: (1) Validation of the physical activity tracker (i.e. the Pebble): 24 volunteer adults walked on a treadmill. The number of steps recorded by the Pebble worn by the subjects was compared with the number of steps counted by the investigators, by means of the Intra-class correlation coefficients (ICC). (2) Measurement of ambulatory physical activity, using the Pebble trackers, over a 7-day period. (3) Relationship between the results obtained with the Pebble trackers (step 2) and subjects' clinical characteristics, linked to physical frailty. RESULTS: ICC data, showed that the reliability of the Pebble was better when it was worn at the foot level (ICC ranged from 0.60 to 0.93 depending on the tested speed). Gait speed is also an important determinant of the reliability, which is better for low gait speed. On average, the 27 nursing home residents included in the second step of this study walked 1678.4±1621 (median=1300) steps per day. Most physical components of frailty measured in this study were significantly different between subjects who walked less than 1300 steps per day and those who were more active. CONCLUSION: This study showed that nursing home residents have a poor ambulatory physical activity, assessed using a physical activity tracker, which is associated with poorer physical performances and higher disability.

RESUMO

BACKGROUND: Gait patterns of healthy aging are needed to allow a comparison with pathological situations. However, little data is available. OBJECTIVE: To present gait pattern of healthy older specially selected to be "healthy walkers". METHOD: Fifty-seven older people benefited from a geriatric assessment including clinical and functional evaluations to include only those without gait disorders. Gait data were simultaneously recorded using a tri-axial accelerometer placed on the waist and four 3D position markers placed on the feet at the level of the heel and the toe. Volunteers walked at comfortable self-selected speed (CW), fast self-selected speed (FW), and finally in dual task walking condition (DTW). The extracted gait parameters were: gait speed, stride length, stride frequency, regularity and symmetry, swing, stance and double support time and ratio and minimum toe clearance. Gait speed and stride length were normalized to the right leg length. RESULTS: Fifty-seven older people with a mean age of 69.7 ± 4.2 years old (range from 65 to 82 years) were included. Data were analyzed according to the gender and according to the age (<70 or ≥70 years old). After normalization to leg length, the main significant differences were shown for stride length and minimum toe clearance in CW, FW and in DTW that were shorter in women. The regularity in FW was significantly lower among older volunteers. CONCLUSIONS: This work provides a data set considering 14 gait parameters obtained from 57 healthy old people strictly selected and assessed for three walking conditions and shows that GS, SL and MTC have to be related to the gender. The age-related impact on gait performances appears reduced in this cohort.

RESUMO

BACKGROUND: The aim of this study was to assess the relationship between frailty and a large number of indicators related to physical and muscular performance as well as quality of life. METHODS: This is an analysis of data collected at baseline in the Sample of Elderly Nursing home Individuals: an Observational Research (SENIOR) cohort including nursing home residents. Subjects are volunteer, oriented and able to walk (walking assistance allowed) nursing home residents in Belgium. A large number of demographic and clinical characteristics, including physical and muscular performance, were collected from each patient. The prevalence of frailty in this population was assessed using Fried's definition. RESULTS: In total, 662 subjects are included in this analysis. The mean age of the sample is 83.2 ± 8.99 years, and 484 (73.1 %) are women. In this population of nursing home residents, the prevalence of frailty is 25.1 %, pre-frailty, 59.8 % and robustness, 15.1 %. Compared to non-frail subjects, frail subjects have lower physical and muscular performances and a lower quality of life. CONCLUSION: Frailty, according to Fried's definition, seems to be associated with several clinical indicators suggesting a higher level of disability and an increased propensity to develop major clinical consequences. Follow-up data of the SENIOR cohort will be helpful in confirming these findings, establishing cause-effect relationships and identifying the most predictive components of physical frailty for adverse outcomes in nursing homes.

RESUMO

Populations considered for shoulder analysis are often composed of various ratios of men and women. It is consequently hypothesized that gender has no significant effect on the joint kinematic. However, the literature reports, for the shoulder, differences in the range of motion between genders. The specific influence of gender on the scapulo-thoracic kinematics has not been studied yet. The dominant shoulder of two populations of men and women composed of 11 subjects each were evaluated in three dimensions for three distinct motions: flexion in the sagittal plane, abduction in the frontal plane and gleno-humeral internal/external rotation with the arm abducted at 90°. Posture, kinematics and range of motion were studied separately. For flexion and abduction and with regard to the scapular kinematic, external rotation was significantly larger for women than men. The differences were of at least 5° at 120° of humeral elevation. Upward rotations were identical. Women also showed larger average active humero-thoracic range of motion. The mean differences were of 13°, 7°, 12° and 5° for abduction, flexion, internal rotation and external rotation, respectively. No difference was observed between the scapular resting positions of both populations. The observed differences concerning both the scapular and humeral patterns would indicate that the shoulder behaviour of men and women should not be expected to be similar.

RESUMO

OBJECTIVES: Some clinical series have evaluated the effect of platelet-rich plasma (PRP) in the treatment of proximal patellar tendinopathy. Although it is possible that a single infiltrative administration may prove to be an effective treatment for this indication, most of the existing studies evaluated the effects of two or three successive infiltrations. The aim of this study was to evaluate whether two infiltrations of PRP proves more effective than a single treatment. DESIGN: Prospective, randomized and comparative study of level 2. METHODS: Twenty patients suffering from chronic proximal patellar tendinopathy were enrolled into the study and split into two randomized groups (one or two infiltrations of PRP, respectively). The 3-month follow-up evaluation consisted of VAS, IKDC and VISA-P scores, along with algometer, isokinetic and ultrasounds evaluations. After 1 year, subjects were contacted to define their functional evolution. RESULTS: The concentration of the PRP used for each infiltration was similar in both groups, and contained no red or white cells. Results revealed no difference in treatment efficacy between the groups. CONCLUSIONS: The comparison between one or two infiltrations of PRP did not reveal any difference between the two groups at short to mid term. A second closely-timed infiltration of PRP to treat proximal patellar tendinopathies is not necessary to improve the efficacy of this treatment in the short term.

RESUMO

BACKGROUND: Previous literature demonstrates the interest of gait analysis to predict cognitive decline in old people. AIMS: This pilot study aims to determine if gait speed or gait variability is a marker able to early identify, among mild cognitive impairment (MCI) subjects, those at risk to develop Alzheimer's disease (AD) in the future. METHODS: 13 MCI subjects were included in 2007. Their gait parameters (walking speed, stride length and gait frequency, regularity and symmetry) were measured in 2007 and 2008 in simple task (ST) and in dual task (DT) using a triaxial accelerometer (Locometrix(®)). Among the 13 MCI subjects included in 2007, 10 were assessed in 2008. So, 23 (13 in 2007 + 10 in 2008) gait tests were collected. In 2011, MCI people were considered as "MCI+" when they developed AD (between baseline and 2011) and as "MCI-" if they did not. Among the 23 gait tests, 15 were from MCI+ (9 gait tests in 2007 and 6 in 2008) and 8 from MCI- (4 gait tests in 2007 and 4 gait tests in 2008). Mann-Whitney non-parametric U test was used to compare gait parameters of MCI+ and MCI-. RESULTS: Gait speed, symmetry and regularity were lower in MCI+ than in MCI-. DISCUSSION: Despite the small sample size, the results presented in this original pilot study are in line as the infrequent previous literature related to this topic. The authors discuss lacks and strengths of this work. CONCLUSIONS: These results suggest that both gait speed and gait variability could be markers to early identify MCI at risk to develop AD.

RESUMO

Classic "passive" therapeutics (anti-inflammatory drugs, infiltrations of corticosteroids...) of tendinopathies, which are used relatively empirically, reduce pain and inflammation, without fundamentally changing the tendon structure. The eccentric rehabilitation has been applied to chronic tendinopathies, not only due to the failure of conventional therapies but also due to a better pathophysiological understanding of tendinopathies. Various studies underscore the effectiveness of eccentric rehabilitation which, after 20-30 sessions, leads to healing and especially prevents the risk of chronicity. Shockwave therapy, amending the tendinous structure, would lead to a long term healing.

RESUMO

To assess the relationship between selected measures (the slope and average performance) obtained during a high intensity isokinetic fatigue test of the knee (FAT) and relevant measures of anaerobic and aerobic capacities. 20 well-trained cyclists performed 3 randomly ordered sessions involving a FAT consisting in 30 reciprocal maximal concentric contractions of knee flexors and extensors at 180°.s(-1), a maximal continuous graded exercise test (GXT), and a Wingate anaerobic test (WAnT). The slope calculated from peak torque (PT) and total work (TW) of knee extensors was highly associated to maximal PT (r=-0.86) and maximal TW (r=-0.87) measured during FAT, and moderately associated to peak power output measured during the WAnT (r=-0.64 to -0.71). Average PT and average TW were highly associated to maximal PT (r=0.93) and maximal TW (r=0.96), to mean power output measured during WAnT (r=0.83-0.90) and moderately associated to maximal oxygen uptake (0.58-0.67). In conclusion, the slope is mainly determined by maximal anaerobic power, while average performance is a composite measure depending on both aerobic and anaerobic energy systems according to proportions that are determined by the duration of the test.

RESUMO

This research aimed to assess the correlation between isometric muscle strength of the lower limb and motor skills. This is a cross sectional study performed among volunteer nursing home residents included in the SENIOR (Sample of Elderly Nursing home Individuals: an Observational Research) cohort. The present analysis focused on isometric muscle strength of 6 lower limb muscle groups (i.e. knee extensors, knee flexors, hip abductors, hip extensors, ankle flexors and ankle extensors), assessed using a validated hand-held dynamometer (i.e. the MicroFET2 device), and motor skills evaluated using the Tinetti test, the Timed Up and Go test, the Short Physical Performance Battery test (SPPB) and the walking speed. The relationship between all these parameters was tested by means of a multiple correlation, adjusted on age, sex and body mass index. 450 nursing home residents (69.8% of women) with a mean age of 83.1±9.4 years were included in this study. Our results showed a significant inverse correlation between lower limb muscle strength and the time required to perform the TUG test or gait speed, except for ankle flexors and ankle extensors. The relationship between the Tinetti test or the SPPB score, and lower limb muscle strength was significant, except for ankle flexors and ankle extensors. In conclusion, a positive association between lower limb muscle strength of the four main muscle groups and motor skills of the elderly nursing residents was found in this research. Therefore, special attention should be given to these muscle groups during rehabilitation programs.

RESUMO

The pathophysiological mechanisms of tendinopathies integrate various intrinsic and extrinsic factors. Classic "passive" therapeutics have a limited action. Because of a better pathophysiological understanding of tendinopathies, more recent treatments (injections of various compounds, infiltrations of platelet-rich plasma, stem cells) would lead to a long-term healing. In case of failure of conservative managements and depending on the anatomical site, a surgical approach may be considered.

RESUMO

AIM: Jumper's knee is a frequent chronic overuse syndrome of the proximal part of the patellar tendon. Platelets contain lots of growth factors which could enhance the healing process of tendons. The aim of this study was to clarify the possible efficacy of one injection of Platelet-rich plasma (PRP) in cases of rebel jumper's knees. METHODS: Twenty patients with chronic proximal patellar tendinopathy were enrolled. Assessments were made before infiltration of PRP, and 6 weeks and 3 months after the infiltration, using a 10-point visual analogic scale of pain, clinical examinations with a pressure algometer, algofunctional scores (IKDC and VISA-P), functional assessments (isokinetic and optojump evaluations) and imagery (ultrasounds and MRI). The PRP was obtained with an apheresis system (COMTEC®, Fresenius-Kabi, Bad Homburg, Germany). Six millilitres of PRP were injected without local anesthetic. One week after infiltration, patients started a standardized sub-maximal eccentric reeducation. RESULTS: During daily activities pain significantly decreased with time. At functional evaluation, it decreased as well, but without significant functional improvement. No improvements in the imagery measurements were observed. Younger patients seemed to be more susceptible to have an improvement of pain by the PRP infiltration. CONCLUSION: This study demonstrates that a local infiltration of PRP associated with a submaximal eccentric protocol can improve symptoms of chronic jumper's knee in patients non-responsive to classical conservative treatments.
