Use of low-cost virtual reality in the treatment of the upper extremity in chronic stroke: a randomized clinical trial.

BACKGROUND: Chronicity and lack of motivation often go together during the upper limb rehabilitation process in stroke. Virtual reality is a useful tool in this context, providing safe, intensive, individualised treatments in a playful environment. B-cost, easy-to-use devices with personalised and motivating games for a specific population seem to be the most effective option in the treatment of the upper limbs. METHODS: A randomised clinical study with follow-up was carried out to assess the effectiveness of the Leap Motion Controller® device in improving the functionality of the upper limb in patients with chronic stroke. Patients (n = 36) were randomised into a control group that performed conventional therapy and an experimental group that combined the virtual reality protocol with conventional therapy. The outcome measures used were grip strength; the Block and Box Test; the Action Research Arm Test; the Disabilities of the Arm, Shoulder and Hand; as well as a Technology Satisfaction Questionnaire and adherence to treatment. RESULTS: Inter-group statistical analysis showed no significant differences except in subsection D of the Action Research Arm Test. Intra-group analysis showed significant differences in both groups, but the experimental group reached significance in all long-term variables. Satisfaction and adherence levels were very high. CONCLUSIONS: The Leap Motion Controller® system, as a complementary tool, produces improvements in grip strength, dexterity and motor function in patients with chronic stroke. It is perceived as a safe, motivating, and easy-to-use device. CLINICAL REGISTRATION: NCT04166617 Clinical Trials.

Conditioned Pain Modulation and Temporal Summation of Pain in Patients With Traumatic and Non-Specific Neck Pain: A Systematic Review and Meta-Analysis.

In patients with neck pain, it is unclear whether pain inhibition and facilitation endogenous pain mechanisms are altered. This systematic review and meta-analysis aimed to improve their understanding by assessing conditioned pain modulation (CPM) and temporal summation of pain (TSP) in patients with neck pain associated with whiplash-associated disorders (WAD) or of a nonspecific neck pain (NSNP) nature compared to pain-free controls. Very low certainty evidence suggests: impaired CPM when assessed remotely in chronic WAD patients (n = 7, 230 patients and 204 controls, standardized mean differences (SMD) = -.47 [-.89 to -.04]; P = .04) but not locally (n = 6, 155 patients and 150 controls; SMD = -.34 [-.68 to .01]; P = .05), impaired CPM in chronic NSNP patients when assessed locally (n = 5, 223 patients and 162 controls; SMD = -.55 [-1.04 to -.06]; P = .04) but not remotely (n = 3, 72 patients and 66 controls; SMD = -.33 [-.92 to .25]; P = .13), TSP not facilitated in either chronic WAD (local TSP: n = 4, 90 patients and 87 controls; SMD = .68 [-.62 to 1.99]) (remote TSP: n = 8, 254 patients and 214 controls; SMD = .18 [-.12 to .48]) or chronic NSNP (local TSP: n = 2, 139 patients and 92 controls; SMD = .21 [-1.00 to 1.41]), (remote TSP: n = 3; 91 patients and 352 controls; SMD = .60 [-1.33 to 2.52]). The evidence is very uncertain whether CPM is impaired and TSP facilitated in patients with WAD and NSNP. PERSPECTIVE: This review and meta-analysis present the current evidence on CPM and TSP in patients with WAD and NSNP. Standardization of measurement methodology is needed to draw clear conclusions. Subsequently, future studies should investigate the clinical relevance of these measurements as prognostic variables or predictors of treatment success.

[Occupational balance, disability and functionality in people with rheumatic disease]. / Equilibrio ocupacional, discapacidad y funcionalidad en personas con enfermedades reumáticaS

BACKGROUND: We aimed to assess the occupational balance of people with rheumatic disease, analyze its relationship with participation, performance, and satisfaction with daily life activities, and evaluate whether age or receiving non-pharmacological treatment affects the outcome. METHODS: Cross-sectional study carried out between March and November 2021; patients with non-advanced stage of rheumatic disease from the ConArtritis Association - selected through simple random sampling -, were included. Sociodemographic data and scores from the OBQ, IMPACT-S, COPM questionnaires, and a questionnaire created ad hoc for daily life activities were collected online and/or by telephone. RESULTS: The occupational balance of the 47 participants was low (OBQ: 34.2; SD: 13.7). Despite a high participation in daily life activities (IMPACT-S: 76.8; SD: 13.1), the degree of performance and satisfaction with these activities was far from optimal (COPM-R: 3.9; SD: 2.0 and COPM-S: 4.3; SD: 2.5); 46.8% of the participants found limitations in at least four daily life activities (basic and instrumental) and 61.7% used at least one support product in their daily lives. These limitations reduced their resting time and affected their jobs, hobbies, and personal relationships. The level of performance was negatively related to age (p=0.04); No changes in the scores were found in patients who received non-pharmacological treatment. CONCLUSIONS: Our results suggest that individuals with non- advanced stage of a rheumatic disease perceive that their occupational balance may be improved should they have fewer limitations in daily life activities.

Equilibrio ocupacional, discapacidad y funcionalidad en personas con enfermedades reumáticas / Occupational balance, disability and functionality in people with rheumatic disease

Fundamento. El objetivo del presente estudio es conocer el equilibrio ocupacional de las personas con enfermedad reumá-tica y analizar su relación con la participación, el rendimiento y satisfacción con las actividades de la vida diaria (AVD), así como evaluar si la edad o recibir tratamiento no farmacológico influ-yen en los resultados.Método. Estudio transversal realizado entre marzo y noviembre de 2021 en personas con diagnóstico de enfermedad reumática en fase no avanzada procedentes de la Asociación ConArtritis, seleccionadas mediante muestreo aleatorio simple. Se recogie-ron, on-line y/o por teléfono, datos sociodemográficos y pun-tuaciones de los cuestionarios OBQ, IMPACT-S, COPM, y de un cuestionario creado ad hoc para las AVD.Resultados. Los 47 participantes no presentaban un buen equi-librio ocupacional (OBQ: 34,2; DE: 13,7). A pesar de una buena participación en AVD (IMPACT-S: 76,8; DE: 13,1), el grado de desempeño y de satisfacción con las AVD distó de ser óptimo (COPM-R: 3,9; DE=2,0 y COPM-S: 4,3; DE=2,5). El 46,8% encon-traba limitaciones en al menos cuatro AVD, tanto básicas como instrumentales, y el 61,7% utilizaba al menos un producto de apoyo en su día a día. Estas limitaciones disminuían su tiem-po de descanso y afectaban a su actividad laboral, aficiones y relaciones personales. El grado de desempeño se relacionó ne-gativamente con la edad (p=0,04); recibir tratamiento no farma-cológico no modificó las puntuaciones.Conclusión. Los datos recabados sugieren que las personas con enfermedad reumática en fases no avanzadas de la enfermedad perciben que su equilibrio ocupacional mejoraría si encontra-sen menos limitaciones en las AVD (AU)

A Novel Active Device for Shoulder Rotation Based on Force Control.

This article describes a one-degree-of-freedom haptic device that can be applied to perform three different exercises for shoulder rehabilitation. The device is based on a force control architecture and an adaptive speed PI controller. It is a portable equipment that is easy to use for any patient, and was optimized for rehabilitating external rotation movements of the shoulder in patients in whom this was limited by muscle-skeletal injuries. The sample consisted of 12 shoulder rehabilitation sessions with different shoulder pathologies that limited their range of shoulder mobility. The mean and standard deviations of the external rotation of shoulder were 42.91 ± 4.53° for the pre-intervention measurements and 53.88 ± 4.26° for the post-intervention measurement. In addition, patients reported high levels of acceptance of the device. Scores on the SUS questionnaire ranged from 65 to 97.5, with an average score of 82.70 ± 9.21, indicating a high degree of acceptance. The preliminary results suggest that the use of this device and the incorporation of such equipment into rehabilitation services could be of great help for patients in their rehabilitation process and for physiotherapists in applying their therapies.

Manual Therapy Effects on Nonspecific Neck Pain Are Not Mediated by Mechanisms Related to Conditioned Pain Modulation: A Randomized Clinical Trial.

BACKGROUND: Manual therapy (MT) is a treatment recommended by clinical practice guidelines in the management of patients with neck pain. However, the mechanisms through which MT works remain unknown. The aim of the present study is to investigate if MT is mediated by mechanisms related to conditioned pain modulation (CPM), comparing the effects of painful with a pain-free MT treatment. METHODS: A two-arm, parallel, randomized controlled clinical trial with concealed allocation and blinding of the outcome assessor was conducted in university students with chronic or recurrent nonspecific neck pain (NSNP). Participants received either a painful or pain-free MT session. Psychophysical variables including pressure pain thresholds, CPM, temporal summation of pain and cold pain intensity were assessed before and immediately after treatment. In addition, changes in neck pain intensity over the following 7 days and self-perceived improvement immediately and 7 days after treatment were assessed. RESULTS: No significant differences were found between groups in any of the psychophysical variables or in patients' self-perceived improvement. Only a significantly greater decrease in neck pain intensity immediately after treatment was found in the pain-free MT group compared to the painful MT group. CONCLUSION: The results suggest that the immediate and short-term effects of MT on NSNP are not mediated by CPM-related mechanisms.

Locomotor adaptation on a split-belt treadmill in adults with stroke: a systematic review.

This systematic review aimed to assess the efficacy of motor adaptation during walking on a split-belt treadmill (SBT) under different learning conditions in adults with stroke. We searched randomized clinical trials and case studies that used SBT under different learning conditions published between January 2011 and April 2022 in four databases: Pubmed, Scopus, Web of Science, and Brain-URJC. The following data were extracted: objectives, interventions, population, number of sessions, outcome measures, and results. The methodological quality of quantitative studies was evaluated using the Critical Review Form. We identified 79 studies, from which six met the criteria for this systematic review (four randomized clinical trials and two case series). The six selected studies included 156 patients with chronic stroke; 62.8% men, age 21-85 years. Walking on a SBT can generate artifacts in the gait pattern depending on the experimental conditions. Two series of cases and one trial reported that the dual motor task - the inclination of the slope of the SBT or the gradual change of speed - promotes the retention of the artifacts generated by the disturbances, resulting in the learning of a new motor pattern. However, combining physical exercise of different intensity and at different times with SBT, maximizing or minimizing errors, or including variable or constant speed disturbances do not seem to affect the locomotor adaptation process.

Kinesiology tape versus non-standardized tape in the treatment of balance in non-operated anterior cruciate ligament rupture patients: a randomized controlled trial.

PURPOSE/AIM: Anterior cruciate ligament injuries are the most common traumatic ligament injuries of the knee, which course with impaired balance. The aim of the present study was to analyse the effect of kinesiology tape on balance in subjects with non-operated anterior cruciate ligament rupture. MATERIALS AND METHODS: 36 subjects were randomly assigned to the kinesiology tape group (KT = 20) and the non-standardized tape group (NST = 16). Balance was assessed in the following 3 conditions: no bandage, immediately after application, and after four days of use. The outcome measures used were the Sensory Organisation Test (SOT), assessed by computerised dynamic Posturography (CDP), the modified star excursion balance test (mSEBT), the Spanish version of the KOOS and the Lysholm Knee Score. A 2-way repeated measures analysis of variance (ANOVA) was performed, with time as a within-subject factor and group as a between-subjects factor. Bonferroni correction was applied when the ANOVA was significant. RESULTS: ANOVA showed that there was no significant interaction between group and time for all outcome measures. However, a significant effect on the time factor was observed for: composite SOT score in both groups immediately after tape application; composite SOT after four days of use in the KT group; mSEBT in the KT group immediately after tape application. The KOOS improved in both groups after four days of tape use, while the Lysholm Knee Score improved only in the NST group. CONCLUSIONS: No differences were observed between the KT or NST groups in balance measurements.

Adaptación locomotora sobre pasarela rodante con correa dividida en personas con ictus: una revisión sistemática / Locomotor adaptation on a split-belt treadmill in adults with stroke: a systematic review

El objetivo de esta revisión fue evaluar la eficacia de la adaptación motora durante la marcha sobre cintas de marcha con correa dividida (CMCD) con diferentes condiciones de aprendizaje en personas con ictus. Se realizó una búsqueda de ensayos clínicos aleatorizados y estudios de casos en cuatro bases de datos (Pubmed, Scopus, Web of Science, Brain-URJC), publicados desde enero de 2011 hasta abril de 2022, que utilizasen CMCD bajo diferentes condiciones de aprendizaje. Se extrajeron datos sobre el objetivo, la intervención, la población, el número de sesiones, las medidas de resultados y los resultados obtenidos. Se valoró la calidad metodologica para estudios cuantitativos con la Critical Review Form.De los 79 estudios identificados, se incluyeron seis en la revisión, cuatro ensayos clínicos aleatorizados y dos series de casos. Incluyeron 156 personas con ictus crónico, 62,8% hombres, entre los 21-85 años de edad. La locomoción sobre CMCD puede generar artefactos en el patrón de marcha, según la condición experimental utilizada. Dos series de casos y un ensayo observaron que la doble tarea motora, la inclinación de la pendiente de la CMCD o el cambio gradual de velocidad, fomentarían la retención de los artefactos generados por las perturbaciones, redundando en el aprendizaje de un nuevo patrón motor.Sin embargo, incluir ejercicio físico de diferente intensidad y en diferentes momentos en combinación con CMCD, maximizar o minimizar los errores, o incluir perturbaciones variables o constantes de la velocidad, parecen no mostrar un efecto sobre el proceso de adaptación locomotora.(AU)

Use of the Leap Motion Controller® System in the Rehabilitation of the Upper Limb in Stroke. A Systematic Review.

OBJECTIVES: Upper limb impairment is the most common motor impairment in stroke survivors. The use of new technologies in the field of rehabilitation aims to reduce the impact of functional problems. Our objective is to evaluate the effectiveness of using the Leap Motion Controller® virtual reality system in the treatment of upper limb functionality in people with stroke. MATERIALS AND METHODS: PRISMA guidelines were used to carry out the systematic review. The literature search was restricted to articles written in English or Spanish published from 2012 to December 2020 in Pubmed, Web of Science, Scopus, PEDro and Science Direct. Of the 309 search results, 230 unique references were reviewed after duplicates were removed. The Downs and Black and CONSORT scales were applied to evaluate the methodological quality of the included papers and the degree of evidence and level of recommendation were determined through the Oxford Centre for Evidence-Based Medicine. RESULTS: Six papers with a total of 144 participants were included in this review, with heterogeneity of the sample, assessment measures, protocols, number of sessions and diversity of games applied. The main results of the studies show favourable data after using the Leap Motion Controller® system in the improvement of upper limb functionality in people with stroke. CONCLUSIONS: There is a growing trend in the use of the Leap Motion Controller® device as a tool in the treatment of the upper limb in people with stroke. Nevertheless, the limitations encountered suggest the need for future research protocols with greater scientific rigor.

Effects of contemporary dance and physiotherapy intervention on balance and postural control in Parkinson's disease.

PURPOSE: To describe the effects of a contemporary dance program, combined with conventional physiotherapy, on postural control, satisfaction and adherence in mild-moderate Parkinson's disease (PD) patients. METHODS: A withdrawal/reversion test with three intervention periods. Each period lasts for two months: physiotherapy, physiotherapy + dance and withdrawing dance and continuing with the physiotherapy sessions. Berg Balance Scale (BBS), Timed Up & Go test (TUG), Sensory Organization Test (SOT), Motor Control Test (MCT) and Rhythmic Weigh Shift (RWS) were assessed at T1 (baseline), T2 (post-physiotherapy treatment), T3 (post-physiotherapy and dance) and T4 (post-physiotherapy). A satisfaction questionnaire and adherence were registered. RESULTS: 27 patients (67.32 ± 6.14 yrs) completed the study. Statistical analysis revealed differences between T2-T3 (p = 0.027), T2-T4 (p = 0.029), T1-T3 (p = 0.010) and T1-T4 (p = 0.008) for BBS; and between T1-T2 (p = 0.037), T1-T3 (p = 0.005), T1-T4 (p = 0.004), T2-T3 (p = 0.022) and T2-T4 (p = 0.041) for TUG. Significant differences for CES (p < 0.001), VEST (p = 0.024) and strategy (p = 0.011) were observed, but not for MCT. Lateromedial velocity (p = 0.003) and anteroposterior velocity (p < 0.001) were significant for RWT. Patients showed a high level of satisfaction and adherence. CONCLUSIONS: A short 8-weeks contemporary dance program plus combined physiotherapy shows benefits in functional mobility and balance, with a high degree of satisfaction and adherence in PD.IMPLICATIONS FOR REHABILITATIONContemporary dance, combined with physiotherapy, is a useful therapeutic tool to treat balance disorders and postural control in people with PD.A short 8-weeks contemporary dance program plus combined physiotherapy shows high satisfaction in people with PD.Contemporary dance, combined with physiotherapy, shows high adherence in people with mild-moderate PD to treat postural control.

Validation of a Hybrid Exoskeleton for Upper Limb Rehabilitation. A Preliminary Study.

Recovery of therapeutic or functional ambulatory capacity in patients with rotator cuff injury is a primary goal of rehabilitation. Wearable powered exoskeletons allow patients to perform repetitive practice with large movements to maximize recovery, even immediately after the acute event. The aim of this paper is to describe the usability, acceptability and acceptance of a hybrid exoskeleton for upper-limb passive rehabilitation using the System Usability Scale (SUS) questionnaire. This equipment, called ExoFlex, is defined as a hybrid exoskeleton since it is made up of rigid and soft components. The exoskeleton mechanical description is presented along with its control system and the way motion is structured in rehabilitation sessions. Seven patients (six women and one man) have participated in the evaluation of this equipment, which are in the range of 50 to 79 years old. Preliminary evidence of the acceptance and usability by both patients and clinicians are very promising, obtaining an average score of 80.71 in the SUS test, as well as good results in a questionnaire that evaluates the clinicians' perceived usability of ExoFlex.

Effects of Transcranial Direct Current Stimulation Combined with Physiotherapy on Gait Pattern, Balance, and Functionality in Stroke Patients. A Systematic Review.

BACKGROUND: The effectiveness of transcranial direct current stimulation (tDCS) together with conventional physiotherapy in motor rehabilitation after stroke has been widely studied. Despite this, few studies have focused on its application in gait and balance rehabilitation. This review aimed to determine the efficacy of transcranial direct current stimulation combined with conventional physiotherapy on gait, balance, and the functionality of the lower limb after stroke. METHODS: This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Four electronic databases were systematically searched for relevant articles. Randomized clinical trials in English or Spanish that evaluated the use of the transcranial direct current stimulation, combined with physiotherapy, to improve gait, balance, and lower limb functionality after stroke were included. MAIN RESULTS: 10 articles were included, with a total of 222 subjects. Data about population, assessment tools, protocols, sessions, and results were extracted. The methodological quality of the included studies ranged between 3 and 5. CONCLUSION: The use of transcranial direct current stimulation combined with physiotherapy improves gait parameters, static and dynamic balance, and lower limb functionality in stroke patients. Long-term effects have not yet been demonstrated.

Comparing the experience of individuals with primary and secondary lymphoedema: A qualitative study.

BACKGROUND: Lymphoedema is a chronic condition that has significant detrimental impact on patients' quality of life. Secondary lymphoedema often results from anti-tumour treatment, in contrast to primary lymphoedema which is the result of genetic abnormalities that leads to an abnormal development of the lymphatic system. OBJECTIVE: To describe and compare the experience of individuals with primary and secondary lymphoedema. METHODS: A total of 19 patients (mean ±â€¯standard deviation age: 56.7 ±â€¯16.2 years), 8 with primary and 11 with secondary lymphoedema, participated in this qualitative phenomenological study. Purposeful sampling method was applied. We recruited participants from specialised lymphoedema units of two physical therapy clinics and the Lymphoedema Patient Association in Spain. Data collection methods included unstructured and semi-structured interviews. An inductive thematic analysis was used. RESULTS: The findings suggest differences between the experience of living with primary or secondary lymphoedema. Also, those with lower extremity lymphoedema have more pain, fatigue, and functional limitations. Three primary themes emerged: "Emotional challenge", "Adapting your life to a new situation," and "lymphoedema management". CONCLUSIONS: The experience of living with lymphoedema involves aspects of fear, suffering, coping, and management of the disease and differs between secondary and primary causes. However, it seems to be more dependent on its location than its cause.

Ankle muscle activation during the limits of stability test in subjects with chronic ankle instability.

OBJECTIVE: To study postural control and muscle activity during the limit of stability test (LOS) in subjects with chronic ankle instability. DESIGN: Observational study. SETTING: University laboratory. PARTICIPANTS: 10 healthy subjects were included in the control group and 10 subjects in the CAI group (age between 18 and 30 years, with history of the multiple ankle "giving way" episodes in the last six months and score ≤24 in the Cumberland Ankle Instability Tool). MAIN OUTCOME MEASURES: A computerized dynamic posturography equipment was used for assessing the LOS. The electromyography activity of tibialis anterior (TA), soleus (SOL), medial gastrocnemius (MG) and peroneus longus (PL) was registered. RESULTS: Subjects with CAI had a greater activation in TA to forward (p < .01), forward affected (p = .001), backward affected (p = .007) and backward directions (p < .01); in PL to forward affected (p < .01) and affected directions (p = .001); in MG to forward (p = .023) and affected directions (p < .01) and in SOL to the affected direction (p = .009). We observed restricted excursions and less directional control in subjects with CAI. CONCLUSIONS: Subjects with CAI exhibited poorer ability to move their center of gravity within stability limits. In addition, they have an altered ankle muscle activity during LOS test toward the affected ankle joint.

Effects of neuro-adaptive electrostimulation therapy on pain and disability in fibromyalgia: A prospective, randomized, double-blind study.

BACKGROUND: To evaluate the effectiveness of non-invasive neuro-adaptive electrostimulation (NAE) therapy for treating chronic pain and disability in patients with fibromyalgia. METHOD/DESIGN: A prospective, randomized, sham-controlled study was conducted in 37 women with fibromyalgia. Participants were randomly assigned to receive either active NAE (n = 20) or stimulation with a sham device (n = 17). Participants in the experimental arm received eight 30-minute sessions over 4 weeks (2 sessions per week). The sham group received eight 30-minute sessions of sham stimulation. Therapeutic effects on pain relief, disability, and quality of life were evaluated using outcome measures at baseline, at 4 weeks, and after 3 months' follow-up. RESULTS: The findings indicated a significant reduction of pain in the active NAE group compared with the sham group immediately post-intervention, with a difference on the Visual Analog Scale (VAS) of 3 points (P = .001), and at 3 months' follow-up (P = .02). There were significant intragroup differences between the groups (P < .05) at post-intervention. After the intervention, both groups presented significant reductions on the Fibromyalgia Impact Questionnaire (FIQ) with respect to baseline (P = .004), but not at the 3-month follow-up. In the conditioned pain modulation (CPM) in thumb variable we found significant differences between the groups at the 3-month follow-up (P = .02). No additional benefits for conditioned pain modulation and disability were observed between groups at the 3-month follow-up. Furthermore, anxiety/depression and catastrophizing improved in both groups, but no differences between groups were found. CONCLUSIONS: In this fibromyalgia cohort, NAE therapy significantly improved pain and quality of life at 4 weeks, but not at 3-month follow-up, compared with the sham stimulation group. Future investigations are needed in larger populations to confirm these findings.

Neuroplasticity Modifications Following a Lower-Limb Amputation: A Systematic Review.

BACKGROUND: Although there are studies that have examined brain functional reorganization following upper-limb amputation, understanding of the brain changes that occur in people with lower-limb amputation is limited. OBJECTIVE: To investigate modifications in the brain following lower-limb amputation. METHODS: We included case-control studies that evaluate neuroplasticity in the central nervous system using neuroimaging techniques. A literature search was conducted using MEDLINE, CINAHL, Web of Science, Scopus, and Cochrane. RESULTS: Eleven articles were included (total n = 204 people with unilateral lower-limb amputation). These studies showed an increase in cerebellar gray matter volume in prosthesis users, as well as a decrease in thickness of the premotor cortex, orbitofrontal cortex, temporo-occipital junction, precentral gyrus, visual areas, and somatosensory cortex. Regarding white matter, the trials observed a decrease in the integrity at the corona radiata, the connections between the premotor areas, the fronto-occipital fasciculus and the corpus callosum. In addition, a decreased functional connectivity between cortical and subcortical areas has been described. CONCLUSIONS: Lower-limb amputation causes changes in several brain structures that may occur in the absence of pain and regardless of prosthesis use. The modifications observed include thinning or loss of gray matter volume, decrease in the integrity of the white matter connections between brain structures and changes in the functional connectivity between cortical and subcortical areas. LEVEL OF EVIDENCE: I.

Postneedling Soreness and Tenderness After Different Dosages of Dry Needling of an Active Myofascial Trigger Point in Patients With Neck Pain: A Randomized Controlled Trial.

BACKGROUND: Previous studies in asymptomatic subjects have demonstrated that myofascial trigger point (MTrP) dry needling frequently is associated with postneedling soreness. However, to the authors' knowledge, there is not any study that performs a detailed description of postneedling soreness characteristics in patients with myofascial pain. This information could help clinicians to make evidence-informed decisions considering the benefits and negative effects of different dry needling dosages. OBJECTIVE: To (1) compare the prevalence, intensity, and duration of postneedling soreness and tenderness after different dosages of deep dry needling (DDN) and (2) analyze the influence on postneedling soreness of psychological factors and other factors involved in the DDN process DESIGN: 1-week follow-up, double-blind randomized controlled trial. SETTING: University community. PARTICIPANTS: Patients (n = 120: 34 male; 86 female) aged 18-53 years (median ± interquartile range, 21.0 ± 7.0 years) with active MTrPs in the upper trapezius. INTERVENTION: All patients received DDN in an active MTrP. They were randomly divided into 4 groups: no local twitch responses (LTRs) elicited (control group), 4 LTRs elicited, 6 LTRs elicited, and DDN until no more LTRs were elicited. MAIN OUTCOME MEASURES: Postneedling soreness and pressure pain threshold were assessed before treatment, during DDN procedure, and every 24 hours during 1 week. RESULTS: Postneedling soreness showed a significant effect for time (F2,006 = 173.603; P < .001, ηp2 = 0.659) and a significant interaction between group and time (F6,017 = 3.763; P = .001; ηp2 = 0.111). Pressure pain threshold showed a significant effect for time (F2,377 = 16.833; P < .001; ηp2 = 0.127) and a significant interaction between group and time (F7,130 = 2.100; P = .04; ηp2 = 0.052). Psychological factors did not show relevant correlations with the intensity of postneedling soreness. CONCLUSIONS: Postneedling soreness is present in most of subjects after DDN of active MTrPs. The groups in which DDN was performed eliciting LTRs exhibited greater post-needling soreness. The number of needle insertions was associated with postneedling soreness but psychological factors did not seem to play a relevant role on its perception.

Living with lymphoedema-the perspective of cancer patients: a qualitative study.

PURPOSE: The aim of this study was to describe the lived experience of lymphoedema and the barriers faced by cancer sufferers receiving physiotherapy outpatient treatment. METHODS: A qualitative, phenomenological study was performed. Purposeful sampling method was used. Data collection methods included unstructured and semi-structured interviews and researcher field notes. A thematic analysis was used. The study was conducted following the Consolidated Criteria for Reporting Qualitative Research guidelines. RESULTS: Eleven patients (62.18 ± 10.14 years) (90.91% women) participated. One theme was identified with different subgroups. The main theme 'Living a life with multiple barriers'-formed by the subthemes 'Discovering physical and psychological barriers', 'Searching information', 'Building relationships' and 'Controlling expenses'-displays the daily difficulties they must face in areas such as work. The patients reported that lymphoedema is a constant emotional and physical challenge. They need to adapt their lives to their new situation, learning how to manage the lymphoedema. CONCLUSIONS: Patients considered lymphoedema as a clinical situation with multiple barriers and they found that it does alter their quality of life. These results can be applied in onco-haematology units to develop specific protocols for customers.
