Respiratory Exercises Versus Manual Therapy and Respiratory Exercises in Moderate Smokers

Universidad Autonoma de Madrid53 enrolled

Overview

The aim of this study is to assess if an intervention of manual therapy and motor control exercises combined with an inspiratory muscle training program is more effective than an inspiratory muscle training program alone in increasing the maximum inspiratory pressure in moderate smokers. In addition, the study pretends to evaluate the changes caused by the intervention regarding possible postural changes and thoracic diameter.

Inclusion Criteria: * Healthy subjects aged between 18 and 60 years and a current smoking rate ≥ 5 points. Exclusion Criteria: * Were excluded participants who presented diagnosis of cardiorespiratory disease, systemic or metabolic disease such as rheumatoid arthritis or cancer, history of thoracic surgery, vertebral fracture, spinal structured musculoskeletal disorders and thoracic region and contraindication to the treatment techniques used (osteoporosis).

Outcomes

Primary Outcomes

Maximum Inspiratory Pressure

The maximum inspiratory pressure (MIP) was measured with a device called Kinetic KH1 Powerbreath (HAB International Ltd., England, UK). This device applies an inspiratory load which provides a resistance. The maneuver was performed in a sitting position. Measuring a minimum of 3 times was performed, recording the highest value.

Secondary Outcomes

Head posture

The head posture was measured through the Cervical Range of Motion (CROM) device. This instrument measures physiological movements of the cervical spine and head position. It´s a reliable method of measuring, providing a range of intra-meter reliability from 0.7 to 0.9 and a range of inter-meter reliability from 0.8 to 0.87. The evaluator instructed the patient to sit in a standardized position and assume a natural position of the head and the goniometer was placed over his head to measure the head posture.

Thoracic kyphosis

The measurement of the thoracic kyphosis was performed through flexicurve. It is a flexible rule that is molded to the back of the subject in order to replicate the shape of the spine. The flexicurve is a valid and reliable tool. The spinous processes of C7 and T12 were located, subsequently it placed on paper 10x10 to draw the curve and to obtained the index flexicurve.

Volumes and lung capacities

The investigators used a simple Spirometry. The Spirometry was performed according to American Thoracic Society criteria with a portable Spirometer model spirobank usb (MIR Rome, Italy). The measures assessed in this outcome were: Forced Vital Capacity (FVC), Forced Expiratory Volume at the First second (FEV1), and Peak Expiratory Flow (PEF). The maneuver was performed 3 times and recording the best one
