Objectives: Todetermine the most appropriate method of functional assessment for "patellofemoral pain" (PFP)/“chondromalacia patella” for its diagnostic value, (validity, reliability, sensitivity, specificity, predictive value and clinical applicability); to outline initial interpretations of the questionnaires and their appropriateness, through the cut-off points determined in their scores based on physical test and Magnetic Resonance Imaging (MRI); to establish which methods should be used in conjunction with each other to obtain clinical diagnoses that are robust effective and efficient. Methods (1)Intra- and inter-observer reliability and of the relationship among PFP questionnaires/ physical tests validated. (2)Predictive capacity of the questionnaires. Subject: 113 knees with PFP, assessed using “Knee-injury-and-Osteoarthritis Outcome-Score-for-Patellofe moral-pain-and-osteoarthritis” (KOOS-PF), “Kujala-Patellofemoral-Score” (KPS), “Victo rian-Institute-of-Sports-Assessment-for-Patellar-tendons-questionnaire” (VISA-P), and the physical tests: “patellar-palpation”, “patellar-tilt”, “patellar-apprehension”, “Clarke” and “squat”. Results Questionnaires correlations themselves was 0.78

Purpose: The aim of the study was to analyze the effects of functional or biomechanical bandages, whether elastic or inelastic, in Chronic Ankle Instability (CAI). • Methods: This review used PubMed, WoS, SCOPUS, and CINAHL following PRISMA and registering in Prospero. Main PICOS: (1) CAI; (2) intervention, functional/biomechanical bandages; (3) comparison, taping effect versus placebo/no taping, or another functional taping; (4) outcomes, improvement of CAI functionality (dynamic/static balance, ankle kinematic, perception, agility and motor control, endurance and strength; (5) experimental and preexperimental studies. The meta-analyses considered mean and s.d. of the results per variable; effect size (ES) of each study and for each type of intervention. Homogeneity (Q), heterogeneity (H2 and I2), and 95% CI were calculated. • Results: In total, 28 studies were selected. Significant differences were found for dynamic balance (66.66%) and static balance (87.5%), ankle kinematics (75.00%), perceptions (88.88%), plantar flexor strength (100%), muscle activity (66.6%), endurance (100%), functional performance (100%), and gait (66.6%). The main results of meta analyses (eight studies) are as follows – h/M ratio soleus, ES: 0.080, 95% CI: −5.219–5.379; h/M ratio peroneus, ES: 0.070, 95% CI: −6.151–6.291; posteromedial KT, ES: 0.042 95% CI: −0.514–0.598; posteromedial—overall, ES: −0.006 95% CI: −1.071–0.819; mSEBT-KT, ES: 0.057 95% CI: −0.281–0.395; mSEBT—overall, ES: −0.035 95% CI: −0.190–0.590. • Conclusions: All biomechanical or functional bandages, whether elastic or inelastic, applied in CAI were favorable, highlighting patient perception, dynamic and static balance, kinematics and agility and motor control, for its effectiveness and evidence. Thus, bandages increase ankle functionality. The meta-analyses found no statistical significance. Clinically, soleus muscle activity, h-reflex/M-responses using fibular reposition with rigid tape, and dynamic balance with comb

Introduction: Alzheimer’s disease causes great changes, with the prefrontal cortex being the most frequently damaged zone; these changes affect physical and cognitive behavior and compromise autonomy. Objective: The objective of this study was to evaluate the effects of physical– cognitive tasks on memory, attention, balance, gait, and risk of falling in Alzheimer’s by using feedback-based technology. Methods: Forty patients with Alzheimer’s were recruited from an Alzheimer’s Association; of these, 15 met the inclusion criteria and were included in the pilot RCT (eight in the control group; seven in the experimental group). Assessment tools: The Cognitive Mini-Examination Scale, Oddball Test and Attention Network, Berg Scale, Tinetti, Timed Up and Go, and Geriatric Deterioration Scale. The experimental group was treated with physical–cognitive tasks by using combined feedback-based technology (visual, acoustic, simultaneous, immediate, and terminal feedback, as well as knowledge of the results and performance) under the supervision of physiotherapists twice per week for 16 thirty-minute sessions. The control group underwent their usual care (pharmacological treatment, mobility exercises, and cognitive stimulation sessions). Result: In the experimental group, the contrast tests showed differences for the re-test (except in attention), with the significative Timed Up and Go test being significant (p = 0.020). The interaction between groups showed significant differences for the experimental group according to the MEC (p = 0.029; d = 0.14) and Tinetti (p = 0.029; d = 0.68). Discussion/Conclusion: Memory, balance, gait, and risk of falling improved in the Alzheimer’s patients through the use of physical–cognitive tasks involving combined feedback-based technology. The effects on attention were inconclusive. The outcomes should be treated with caution due to the sample. This can promote intergenerational bonds, use at home, and adherence to treatment.

Aging raises a social and health challenge because the passing of time causes changes in cognitive and physical functions that impair functionality and quality of life. In addition, advancements in technology and information technology have led to the development of new techniques for retraining based on the feedback technology provides. To solve the negative consequences of aging, a randomized clinical trial was carried out to assess the effectiveness of a protocol using feedback-based technology to improve physical and cognitive functions in older adults. For the purpose of this study, 200 patients were selected from a Social and Community Services Center in the province of Seville and only 46 of them became participants of the study (after applying the inclusion criteria). These patients were divided into two groups: control and experimental. Physical and cognitive abilities were assessed using the Miniexamen cognoscitivo Test (an adaptation of the MiniMental examination test), Yesevage’s Depression Scale, Oddball Test, Attention Network Test, Berg Scale, Tinetti Scale, and Timed Up and Go Test. The intervention applied to the experimental group consisted of a supervised protocol using the Nintendo R Wii video game console and the Wii-Fit© video game during 16 sessions, 2 times a week with a duration of 30 min per session. The control group did not receive any treatment. The experimental group showed statistically significant improvements in all the physical variables (balance, gait, autonomy, and fall risk), as other authors had proven, and in memory and reaction times; there were no improvements in attention networks. The control group (placebo) even showed a decrease in their functions, with worse results on the Timed up and Go test Scale. The intervention using feedback-based technology has been proven effective in improving physical and cognitive abilities and in preventing and promoting healthy aging.

Evaluating the emotional state of parents is important for determining the intervention in the context of a family with a baby with Down syndrome. “This is my baby” is an interview that measures the acceptance, commitment and awareness of influence of parents towards their baby. The Spanish adaptation of this instrument helps to better understand the emotional state of parents of children with developmental disorders. A cross-cultural adaptation and reliability analysis was carried out. The results suggest that the Spanish version of the This Is My Baby interview is a reliable instrument to measure the levels of acceptance, commitment and awareness of influence of parents of an infant with Down syndrome.

Background: Functional rating scales allow clinicians to document and quantify alterations and progression of recovery processes. There is neither awareness of numerous knee scales nor are they easy to find or compare to select the most suitable. Objectives: We aimed to compile validated knee functional rating tools and analyze the methodological qual ity of their validation studies. Also, we aimed to provide an operational document of the outcome measures addressing descriptions of parameters, implementations, instructions, interpretations and languages, to identify the most appropriate for future interventions. Methods: A systematic review involved a search of PubMed, Web of Science, CINAHL, Scopus, and Dialnet databases from inception through September 2020. The main inclusion criteria were available functional rat ing scales/questionnaires/indexes for knees and validation studies. Methodological quality was analyzed with the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) and COnsensus-based Standards for the selection of health Measurement Instruments Risk of Bias (COSMIN-RB). Results: We selected 73 studies. The studies investigated 41 knee rating tools (general, 46%, and specific, 54%) and 71 validations, including 29,742 individuals with knee disorders. QUADAS-2 obtained the best results in patient selection and index test (applicability section). COSMIN-RB showed the highest quality in construct validity (most analyzed metric property). The specific tools were mainly designed for prosthesis and patello femoral and anterior cruciate ligament injuries. More considered issues were specific function (93%), espe cially gait, pain/sensitivity (81%), and physical activity/sports (56%). Conclusions and implications: We conducted a necessary, useful, unlimited-by-time and feasible compilation of validated tools for assessing knee functional recovery. The methodological quality of the validations was limited. The best validations were for the Copenhagen

Background: The aim of this systematic review and meta-analysis was to evaluate the global postural re-education (GPR) program’s effectiveness compared to other exercise programs in subjects with persistent chronic low back pain. Methods: A systematic review and meta-analysis were carried out using PRISMA2020. An electronic search of scientific databases was performed from their inception to January 2021. Randomized controlled trials that analyzed pain and patient-reported outcomes were included in this review. Four meta-analyses were performed. The outcomes analyzed were disability due to back pain and pain. The risk of bias and quality of evidence were evaluated. The final search was conducted in March. Results: Seven trials were included, totaling 334 patients. The results showed improvement in pain measured by Visual Analogue Scale (VAS) (Standardised Mean Difference (SMD) = −0.69; 95% Confidence Interval (CI), −1.01 to −0.37; p < 0.0001), Numerical Pain Scale (NRS) (SMD = −0.40; 95% CI, −0.87 to 0.06); p = 0.022), VAS + NRS (SMD = −1.32; 95% CI, −1.87 to −0.77; p < 0.0001) and function (Roland Morris Disability Questionnaire (RMDQ)) (SMD = −0.55; 95% CI, −0.83 to −0.27; p < 0.0001) after GPR treatment. Conclusion: This meta-analysis provides reliable evidence that GPR may be an effective method for treating LBP by decreasing pain and improving function, with strong evidence.

Background The important functional role the rotator cuff (RC) and biceps play in the shoulder, the close anatomical relationship between them and the high incidence of injuries require an appropriate multidisciplinary therapeutic approach after a rigorous assessment. The objective is to identify and analyze surgical interventions, whether or not followed by a postsurgical one, of associated dysfunctions on the RC and long head of the biceps (LHB) and their effectiveness in improving shoulder functionality. Methods A systematic review based on PRISMA protocol was conducted using PubMed, Web of Science, PEDro, Scopus, CINAHL, and Dialnet until 22 April 2021. The main inclusion criteria were as follows: randomized clinical trials including subjects diagnosed with RC and LHB lesions who had surgical and/not post-surgical treatments. The methodological quality of trials was evaluated by the PEDro scale. Data were shown in 3 pre-established tables: (1)sample data, diagnostic methods, dysfunctions and injury frequency, interventions, outcome measures and results; (2)significance and effectiveness of interventions; and (3)comparison of the effectiveness of interventions. Results Eleven studies were selected. The methodological quality of ten of them was assessed as good and one excellent (PEDro scale). All articles had surgical treatments and ten had postoperative management. All trials used arthroscopy and two open surgery too. Single-row, double-row and transosseous repair were used for RC lesions, while SLAP repair, tenotomy, and tenodesis were applied to LHB injuries. Measured parameters were functionality, pain, Popeye's sign, strength, range of motion, satisfaction degree, biceps cramping, and quality of life. All approaches in general, surgical plus postsurgical, were always effective to the parameters measured in each study. Seven trials compared tenotomy and tenodesis: four of them obtained statistically significant differences in favor of tenodesis in Popeye's si

Background: Rotator cuff (RC) tendinopathy causes pain and functional limitation of the shoulder. Physical exercises are effective therapies but there is no consensus on which exercise programme is the most appropriate. Objective: To analyze and compare the effectiveness of different intervention modalities-based exclusively on physical exercise muscle-development programs to improve shoulder pain and function in RC tendinopathy. (2) Methods: Systematic review (PRISMA) through a search in PubMed, WOS, PEDro, Cinahl, Scopus and Dialnet. The PEDro Scale and the Cochrane Risk of Bias analyzed the methodological quality. A pre-established table collected data on: patients, interventions, outcome measures and results. A narrative synthesis of the results was conducted. (3) Results: eight articles were selected (Cochrane: low risk of bias; PEDro: good quality). All assessed programs were effective. Only one study found statistically and clinically significant differences in favour of eccentric training. The exercises used were: eccentric/concentric/conventional, open/closed kinetic chain, with/without co-activation of glenohumeral muscle, with/without pain, and in clinic/at home. (4) Conclusions: All exercise programs were effective in RC tendinopathy, improving pain and shoulder function. No solid results were obtained when the interventions were compared due to their heterogeneity. Patients perception assessment tools were the most widely used. Amount of load applied should be considered.

Objective: To analyze the exercise programs used to prevent of acute hamstring injuries in eleven-a-side football players, and their effectiveness. (2) Methods: A systematic review (PRISMA) was conducted (2008–2020), including RCTs, that exclusively used physical exercises as a prevention method. (3) Results: Ten studies were selected considering 14 interventions, including nine different programs: FIFA11+ (11+), Harmoknee, eccentric Nordic Hamstring Exercise (NHE) exclusively, with eccentric exercises, with stretching or with proprioceptive, New Warm-up Program (NWP), Bounding Exercise Program (BEP), the only one with no positive results, and proprioceptive exercises. Incidence of injuries and strength were the most considered variables, both with favorable evidences. Programs including NHE, which assessed injury incidence, were always effective. The 11+ program was effective in injury incidence and strength; NWP was effective in balance, stability, and strength. (4) Conclusions: The exercise programs discussed were effective to prevent acute hamstring injuries in football players except BEP and partially Harmoknee. Exercises mostly used to reduce the risk of hamstring injuries are those of eccentric force due to its functionality, especially NHE. Only concentric contractions and isometric contractions obtained significant favorable results. The most complete and promising programs were 11+ (in injury incidence and strength) and NWP (strength, balance, and stability). NWP was the best in strength.

The objective of this review was to compile validated functional shoulder assessment tools and analyse the methodological quality of their validations. Secondarily, we aimed to provide a comparison of the tools, including parameter descriptions, indications/applications, languages and operating instructions, to choose the most suitable for future clinical and research approaches. A systematic review (PRISMA) was conducted using: PubMed, WoS Scopus, CINHAL, Dialnet and reference lists until 2020. The main criteria for inclusion were that papers were original studies of validated tools or validation studies. Pre-established tables showed tools, validations, items/components, etc. The QUADAS-2 and COSMIN-RB were used to assess the methodological quality of validations. Ultimately, 85 studies were selected, 32 tools and 111 validations. Risk of bias scored lower than applicability, and patient selection got the best scores (QUADAS-2). Internal consistency had the highest quality and PROMs development the lowest (COSMIN-RB). Responsiveness was the most analysed metric property. Modified UCLA and SST obtained the highest quality in shoulder instability surgery, and SPADI in pain. The most approached topic was activities of daily living (81%). We compiled 32 validated functional shoulder assessment tools, and conducted an analysis of the methodological quality of 111 validations associated with them. Modified UCLA and SST showed the highest methodological quality in instability surgery and SPADI in pain.

Background: Measuring weight bearing is an essential aspect of clinical care for lower limb injuries such as sprains or meniscopathy surgeries. This care often involves the use of forearm crutches for partial loads progressing to full loads. Therefore, feasible methods of load monitoring for daily clinical use are needed. Objective: The main objective of this study was to design an innovative multifunctional desktop load-measuring software that complements GCH System 2.0-instrumented forearm crutches and monitors the applied loads, displaying real-time graphical and numerical information, and enabling the correction of inaccuracies through feedback technology during assisted gait. The secondary objective was to perform a preliminary implementation trial. Methods: The software was designed for indoor use (clinics/laboratories). This software translates the crutch sensor signal in millivolts into force units, records and analyzes data (10-80 Hz), and provides real-time effective curves of the loads exerted on crutches. It covers numerous types of extrinsic feedback, including visual, acoustic (verbal/beeps), concurrent, terminal, and descriptive feedback, and includes a clinical and research use database. An observational descriptive pilot study was performed with 10 healthy subjects experienced in bilateral assisted gait. The Wilcoxon matched-pairs signed-rank test was used to evaluate the load accuracy evolution of each subject (ie, changes in the loads exerted on crutches for each support) among various walks, which was interpreted at the 95% confidence level. Results: GCH Control Software was developed as a multifunctional desktop tool complementing GCH System 2.0-instrumented forearm crutches. The pilot implementation of the feedback mechanism observed 96/100 load errors at baseline (walk 0, no feedback) with 7/10 subjects exhibiting crutch overloading. Errors ranged from 61.09% to 203.98%, demonstrating heterogeneity. The double-bar feedback found 54/100 errors

The aim of this study was to identify and to assess the best evidence currently available on the effectiveness of oral sensory-motor stimulation in preterm infants in the neonatal intensive care unit. We performed a systematic review following the Preferred Reporting Items for Systematic Reviews (PRISMA) statements. The search was conducted using the Pubmed, Web of Science (WOS), PEDro and Scopus databases. Clinical trials were reviewed and PEDro rating scale was used to assess the methodological quality of these studies. Results: 1267 studies were found and 11 were relevant and included in this review. Improvements were obtained in achieving independent feeding, maturation of the sucking pattern, transition to full feeding, motor function and length of hospital stay in most studies. Conclusions: there is evidence to support the benefits of the use of oral sensorimotor stimulation to achieve independent oral feeding in preterm infants, thereby reducing their stay in the Neonatal Intensive Care Unit.

Objectives. Proprioceptive training is popularly applied as a therapeutic exercise method in physiotherapy. Its effects on pain and range of motion are only poorly evaluated. Therefore, this study assesses the effectiveness of proprioceptive training with an Eye- Cervical Re-education Program to decrease pain and increase the joint range in chronic neck pain patients. Material and Methods. Design. A randomized, no-blinded, controlled clinical trial. Setting. Physiotherapy consultation. Participants. 44 people were divided into two groups. Interventions. All patients were treated with a multimodal physiotherapy intervention. The experimental group was supplemented with an exercise program that included eye-cervical proprioception. Outcomes. The primary outcomes included pain pressure thresholds (upper trapezius, levator scapulae, and splenius capitis) and cervical range of motion. The secondary outcomes included pain measured by the Visual Analogical Scale and the McGillSpv Questionnaire. Results. The proprioception treatment was effective in reducing the pain pressure threshold in the right upper trapezius (p = 0.001), left upper trapezius (p = 0.014), right levator scapula (p = 0.040), and left splenius capitis (p = 0.021). The increase in the joint range was statistically significant (p < 0.05) in favor of the Eye-Cervical Re-education Program for all movements assessed. Conclusions. The Eye-Cervical Re-education Program is effective at relieving pain pressure thresholds in the upper trapezius, right levator scapula, and left splenius capitis and especially effective for increasing the cervical range of motion. This trial is registered with NCT03197285 (retrospective registration)

Objective. To compile and analyze the characteristics and methodological quality of observational gait assessment scales validated to date. Methods. PubMed, Scopus, the Cochrane Library, Physiotherapy Evidence Database, Web of Science, Cumulative Index to Nursing and Allied Health Literature, Dialnet, Spanish Medical Index, and Nursing, Physiotherapy, and Podiatry databases were searched up to August 2019. ,e main inclusion criteria were validated tools based on a conceptual framework developed to evaluate gait, validation design studies of observational scales in their entirety, and articles written in English or Spanish. Evaluators extracted descriptive information of the scales and the metric properties of the studies, which were further analyzed with Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) and COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN checklist). Results. Eighteen articles based on 14 scales were included. ,e populations were neurological patients (72.22%), musculoskeletal disorders (11.11%), and other areas such as vestibular disorders (11.11%). ,e most addressed items were orthopedic aids (64.29%); phases of the gait cycle and kinematics of the leg and trunk (57.14% each one); and spatial and temporal parameters (50%). All studies analyzed criterion validity, and five included content or structural validity (27.78%). Fifteen articles considered reliability (83.33%). Regarding the seven-item scale QUADAS-2, five studies obtained six results on “low” risk of bias or “low” concerns regarding applicability. Nine articles obtained at least a “fair” result on COSMIN checklist. Conclusions. A necessary compilation of the observational gait assessment scales validated to date was conducted. Besides, their characteristics and methodological quality were analyzed. Most scales were applied in neurological signs. ,e most approached topics were orthopedic aids, phases of the gait cycle, and kinematics of the

La reeducación de la marcha es parte fundamental del tratamiento de multitud de pacientes en Fisioterapia. Para este proceso de recuperación resulta imprescindible la valoración, tanto inicial, como evolutiva y final. Con el fin de valorar esta función motriz, se ha diseñado una gran variedad de herramientas. Por un lado, las escalas de valoración visual, basadas en el examen observacional. Estos procedimientos están disponibles para su empleo en cualquier ámbito asistencial o investigador, aunque tienen limitaciones como la falta de validación de muchos de ellos. Por otro lado, sofisticados sistemas tecnológicos, que aportan información fiable y objetiva para caracterizar el movimiento. Estos dispositivos cuentan, a pesar de ello, con limitaciones como un alto coste económico o un elevado nivel de destreza en su empleo. La combinación de los sistemas observacionales y tecnológicos con objeto de valorar la marcha asistida es llevada a cabo de forma novedosa en esta Tesis Doctoral. Así se complementan los beneficios de ambos métodos para lograr una evaluación completa, objetiva, analítica y global de la marcha asistida del paciente. Este estudio se centra en la marcha asistida con bastones de antebrazo en dos tiempos por ser una modalidad frecuentemente empleada durante la reeducación de la marcha de pacientes que precisan descargar un miembro inferior afecto a causa de una lesión musculoesquelética. De este modo, el objetivo principal de esta Tesis fue diseñar, desarrollar y validar nuevas herramientas de valoración, observacional y tecnológica complementarias, en la marcha asistida con bastones de antebrazo para descargar un miembro inferior afecto debido a una lesión musculoesquelética; así como analizar los parámetros espaciotemporales del paso mediante protocolos innovadores. El abordaje de este propósito se realiza en el marco de una Tesis por Compendio de tres publicaciones científicas. Así, el primer estudio del compendio presenta la creación, desarrollo y va

This systematic review synthesized and analyzed clinical findings related to the effectiveness of innovative technological feedback for tackling functional gait recovery. An electronic search of PUBMED, PEDro, WOS, CINAHL, and DIALNET was conducted from January 2011 to December 2016. The main inclusion criteria were: patients with modified or abnormal gait; application of technology-based feedback to deal with functional recovery of gait; any comparison between different kinds of feedback applied by means of technology, or any comparison between technological and non-technological feedback; and randomized controlled trials. Twenty papers were included. The populations were neurological patients (75%), orthopedic and healthy subjects. All participants were adults, bar one. Four studies used exoskeletons, 6 load platforms and 5 pressure sensors. The breakdown of the type of feedback used was as follows: 60% visual, 40% acoustic and 15% haptic. 55% used terminal feedback versus 65% simultaneous feedback. Prescriptive feedback was used in 60% of cases, while 50% used descriptive feedback. 62.5% and 58.33% of the trials showed a significant effect in improving step length and speed, respectively. Efficacy in improving other gait parameters such as balance or range of movement is observed in more than 75% of the studies with significant outcomes. Conclusion: Treatments based on feedback using innovative technology in patients with abnormal gait are mostly effective in improving gait parameters and therefore useful for the functional recovery of patients. The most frequently highlighted types of feedback were immediate visual feedback followed by terminal and immediate acoustic feedback.

Background: Assisted gait with forearm crutches is frequently performed during the recovery of musculoskeletal injuries of the lower limb. The amount of body weight applied to the crutch or crutches depends on the pathology and the treatment phase. The transition from assisted gait with two crutches to a single crutch is usually rec‑ ommended when the subject is able to load the 50% of the body weight upon the afected member. An altered assisted gait will cause biomechanic alterations and, therefore, longer treatments and relapses. The aim of this study was to analyze the infuence of 10, 25 and 50% of body weight applied to a forearm crutch during a uni‑ lateral assisted gait in the spatial and temporal step parameters to determine the load that produces alterations in gait biomechanics and the load that does not. Methods: Eleven healthy subjects performed normal gait (NG) and assisted gait with a forearm crutch, in which the applied loads were: comfortable (C), 25 and 50% of their body weight. Vicon System was employed for gait recording. GCH System 2.0 and GCH Control Software 1.0 controlled the loads. The variables were: step length, step period, velocity, step width and step angle. Friedman test compared all the gait modalities: NG and the diferent loads. Wilcoxon signed-rank test analyzed ipsilateral and contralateral step parameters to the crutch globally and for each subject. Results: Friedman test showed signifcant diferences between NG, C, 25 and 50%, especially for step period and velocity. Wilcoxon test had signifcant diferences only in 4 of the 20 general comparisons between ipsilateral and contralateral steps to the crutch. In the analysis by subjects, step length, step period and velocity showed 79/132, 110/132 and 58/66 signifcant diferences, respectively. Conclusions: The increase in the load exerted over a forearm crutch produced an increase in the step period, accompanied by a reduction of step length and gait veloc‑ ity. Step width and step angle

Diversas afecciones del miembro inferior requieren de un periodo de descarga total o parcial durante el proceso de recuperación. La marcha asistida es una de las estrategias de intervención en Fisioterapia más relevantes para facilitar el proceso de curación de la extremidad inferior afectada. A menudo se emplea el uso de bastones canadienses como dispositivo de ayuda a la ambulación, logrando así una marcha funcionalmente eficiente y biomecánicamente correcta. Sin embargo, su uso incorrecto, el incumplimiento de las cargas prescritas por el fisioterapeuta, la toma de desiciones subjetivas del profesional o del propio paciente pueden provocar: dolor, restricciones del rango de movilidad, alteraciones de la función muscular, compensaciones, recaídas y secuelas secundarias. Pese a su importancia, no hay estudios que aúnen criterios para establecer la progresión en las cargas ni en el número de bastones que deben ser utilizados. Con este estudio pretendemos realizar una propuesta para ayudar a los profesionales a tomar decisiones objetivas y fiables, sobre cuál es el porcentaje de peso más recomendable para emplear dos bastones y cuál será la progresión hacia el uso de un bastón, así como la retirada del mismo. Para ello, será fundamental conocer previamente cómo se desvirtúa el gesto de la marcha y la movilidad en relación con los porcentajes de carga aplicados sobre los bastones. En este estudio, la utilización del Sistema de Medición de Cargas GCH 2.0, que son bastones instrumentados, nos proporcionan la información real del porcentaje de carga aplicado sobre éstos, y junto con el análisis de movimiento tridimensional de cabeza, tronco, pelvis y hemipelvis, nos han permitido analizar la cinemática en los tres planos de movimiento de los mismos. De esta forma, estudiamos la marcha asistida contralateral ejerciendo el 10%, 25% y 50% del peso corporal sobre el bastón, así como la marcha bilateral cargando el 25% y 50% del peso corporal sobre los dos bastones, para ver

Frequently, patients who suffer injuries in some lower member require forearm crutches in order to partially unload weight-bearing. These lesions cause pain in lower limb unloading and their progression should be controlled objectively to avoid significant errors in accuracy and, consequently, complications and after effects in lesions. The design of a new and feasible tool that allows us to control and improve the accuracy of loads exerted on crutches during aided gait is necessary, so as to unburden the lower limbs. In this paper, we describe such a system based on a force sensor, which we have named the GCH System 2.0. Furthermore, we determine the validity and reliability of measurements obtained using this tool via a comparison with the validated AMTI (Advanced Mechanical Technology, Inc., Watertown, MA, USA) OR6-7-2000 Platform. An intra-class correlation coefficient demonstrated excellent agreement between the AMTI Platform and the GCH System. A regression line to determine the predictive ability of the GCH system towards the AMTI Platform was found, which obtained a precision of 99.3%. A detailed statistical analysis is presented for all the measurements and also segregated for several requested loads on the crutches (10%, 25% and 50% of body weight). Our results show that our system, designed for assessing loads exerted by patients on forearm crutches during assisted gait, provides valid and reliable measurements of loads.

Objective The aim of this study was to design and validate a functional assessment scale for assisted gait with forearm crutches (Chamorro Assisted Gait Scale—CHAGS) and to assess its reliability in people with sprained ankles. Design Thirty subjects who suffered from sprained ankle (anterior talofibular ligament first and second degree) were included in the study. A modified Delphi technique was used to obtain the content validity. The selected items were: pelvic and scapular girdle dissociation(1), deviation of Center of Gravity(2), crutch inclination(3), steps rhythm(4), symmetry of step length(5), cross support(6), simultaneous support of foot and crutch(7), forearm off(8), facing forward(9) and fluency(10). Two raters twice visualized the gait of the sample subjects which were recorded. The criterion-related validity was determined by correlation between CHAGS and Coding of eight criteria of qualitative gait analysis (Viel Coding). Internal consistency and inter and intra-rater reliability were also tested. Results CHAGS obtained a high and negative correlation with Viel Coding. We obtained a good internal consistency and the intra-class correlation coefficients oscillated between 0.97 and 0.99, while the minimal detectable changes were acceptable. Conclusion CHAGS scale is a valid and reliable tool for assessing assisted gait with crutches in people with sprained ankles to perform partial relief of lower limbs.
