The effect of thoracic manipulation on pulmonary function in swimmers / Efecto de la manipulación torácica en la función pulmonar de nadadores / Efeito da manipulação torácica na função pulmonar em nadadores

Objective: Spinal manipulation has been used to improve respiratory function in healthy individuals. However, it has been observed that there are no studies in the context of sports activities. The objective of this study was to analyse the effect of thoracic spinal manipulation on forced vital capacity, forced expiratory volume in one second and maximal voluntary ventilation in swimmers.Method: A randomized controlled crossover study consisting of 21 swimmers, divided into two groups (Intervention vs Control), aged 16 – 24y, where forced vital capacity, forced expiratory volume in one second and maximal voluntary ventilation were measured in five evaluation moments: at baseline and, 1 minute, 10 minutes, 20 minutes and 30 minutes following the thoracic spinal manipulation procedures.Results: ANOVA tests showed no statistically significant differences for forced vital capacity (p = 0.35) and forced expiratory volume in one second (p = 0.25) among the five evaluation moments. With the maximal voluntary ventilation there was a statistically significant (p = 0.02) reduction, observed between baseline (86.00 litres) and at 10 minutes (79.29 litres) and 30 minutes (76.24 litres). No significant differences were observed between the results of intervention and control groups.Conclusions: In the current study no significant differences were observed in pulmonary function after thoracic spinal manipulation. Future research efforts should examine the effects of different manual therapy techniques and treatment protocols. (AU)

Objetivo: La manipulación espinal se ha utilizado para mejorar la función respiratoria en individuos sanos. Sin embargo, se ha observado que no hay estudios en el contexto de las actividades deportivas. El objetivo de este estudio fue analizar el efecto de la manipulación de la columna torácica en la capacidad vital forzada, el volumen espiratorio forzado en el primer segundo y la ventilación voluntaria máxima en nadadores.Método: Un estudio cruzado controlado aleatorio que consta de 21 nadadores, divididos en dos grupos (Intervención vs Control), de 16 a 24 años, donde se midieron la capacidad vital forzada, el volumen espiratorio forzado en el primer segundo y la ventilación voluntaria máxima en cinco momentos de evaluación: al inicio y, 1 minuto, 10 minutos, 20 minutos y 30 minutos después de los procedimientos de la manipulación de la columna torácica.Resultados: Las pruebas ANOVA no mostraron diferencias estadísticamente significativas para la capacidad vital forzada (p = 0.35) y el volumen espiratorio forzado en el primer segundo (p = 0.25) entre los cinco momentos de evaluación. Con la ventilación voluntaria máxima hubo una reducción estadísticamente significativa (p = 0.02), observada entre lo inicio (86.00 litros) y a los 10 minutos (79.29 litros) y 30 minutos (76.24 litros). No se observaron diferencias significativas entre los resultados de los grupos de intervención y control.Conclusiones: En el presente estudio, no se observaron diferencias significativas en la función pulmonar después de la manipulación de la columna torácica. Futuros estudios de investigación deberían examinar los efectos de diferentes técnicas de terapia manual y protocolos de tratamiento. (AU)

Objetivo: A manipulação da coluna vertebral tem sido utilizada para melhorar a função respiratória em indivíduos saudáveis. No entanto, observou-se que não existem estudos no contexto de atividades desportivas. O objetivo deste estudo foi analisar o efeito da manipulação da coluna torácica na capacidade vital forçada, volume expiratório forçado no primeiro segundo e ventilação voluntária máxima em nadadores.Método: Estudo aleatorizado controlado cruzado composto por 21 nadadores, divididos em dois grupos (Intervenção vs Controlo), com idades entre 16 e 24 anos, onde a capacidade vital forçada, volume expiratório forçado no primeiro segundo e ventilação voluntária máxima foram medidos em cinco momentos de avaliação: no início e, 1 minuto, 10 minutos, 20 minutos e 30 minutos após os procedimentos da manipulação da coluna torácica.Resultados: Os testes ANOVA não mostraram diferenças estatisticamente significativas para a capacidade vital forçada (p = 0.35) e volume expiratório forçado no primeiro segundo (p = 0.25) entre os cinco momentos da avaliação. Com a ventilação voluntária máxima houve uma redução estatisticamente significante (p = 0.02), observada entre o início (86.00 litros) e as medições aos 10 minutos (79.29 litros) e 30 minutos (76.24 litros). Não foram observadas diferenças significativas entre os resultados dos grupos intervenção e controlo.Conclusões: No presente estudo, não foram observadas diferenças significativas na função pulmonar após a manipulação da coluna torácica. Futuras pesquisas devem examinar os efeitos de diferentes técnicas de terapia manual e protocolos de tratamento. (AU)

The effects of training and detraining after an 8 month resistance and stretching training program on forward head and protracted shoulder postures in adolescents: Randomised controlled study.

PURPOSE: This study aimed to evaluate the effects of a 32-week resistance and stretching training program applied in Physical Education classes on forward head posture and protracted shoulder posture of Portuguese adolescents (15-17 years old). The detraining effects after a 16-week period were also measured. METHODS: This prospective, randomized and controlled study was conducted in two secondary schools in Portugal. One hundred and thirty adolescents with forward head and protracted shoulder posture were randomly assigned to a control or experimental group. The sagittal head, cervical and shoulder angle were measured before and after a 32-week time intervention period. The control group (n = 46) did only the Physical Education classes whereas the exercise group (n = 42) received a posture corrective exercise programme in addition to Physical Education classes. A 16 week detraining period followed the 32-week. RESULTS: Significant increase were observed in the cervical and shoulder angle in the experimental group following the 32 week-intervention period. After the 16-week detraining period no significant differences were observed in the three postural angles in the intervention group. CONCLUSIONS: The exercise intervention was successful at decreasing forward head and protracted shoulder in adolescents. Detraining period was not sufficient to reduce the overall training effects. This study supports the postural training and rehabilitation performed during Physical Education classes, with the aim of preventing and managing upper quadrant musculoskeletal pain. CLINICALTRIALS.

New concepts in restoring shoulder elevation in a stiff and painful shoulder patient.

The treatment and evaluation of a stiff and painful shoulder, characteristic of adhesive capsulitis and "frozen" shoulders, is a dilemma for orthopedic rehabilitation specialists. A stiff and painful shoulder is all-inclusive of Adhesive capsulitis and Frozen Shoulder diagnoses. Adhesive capsulitis and frozen shoulder will be referred to as a stiff and painful shoulder, throughout this paper. Shoulder motion occurs in multiple planes of movement. Loss of shoulder mobility can result in significant functional impairment. The traditional treatment approach to restore shoulder mobility emphasizes mobilization of the shoulder overhead. Forced elevation in a stiff and painful shoulder can be painful and potentially destructive to the glenohumeral joint. This manuscript will introduce a new biomechanical approach to evaluate and treat patients with stiff and painful shoulders.
