Aim of the Study

To evaluate the influence of proprioceptive neuromuscular facilitation techniques on diaphragm muscle activity and pulmonary function in subjects with guillain- barre syndrome.

Purpose of the Study

Respiratory muscle weaknesses in neuromuscular diseases are major causes of morbidity and mortality in acute and long term setting. Indications for admission of patients with guillain- barre syndrome in ICU often include one or more factors like respiratory failure, severe bulbar weakness, and autonomic instability. Although, regular physiotherapy includes – air way clearance techniques, breathing exercises, chest physiotherapy, body positioning, postural drainage positions, inspiratory and expiratory muscle training, all these may improve the chest condition but the subject may not completely recover from respiratory muscle weakness and may have fatigue. Proprioceptive neuromuscular facilitation techniques facilitate the respiratory muscles which in turn improves the pulmonary function. Hence, the purpose of the study is to find out the influence of PNF techniques on diaphragm muscle activity and on pulmonary function (FEV1/FVC) in subjects with guillain- barre syndrome.

Objectives of the Study

  • To evaluate the effect of PNF techniques on pulmonary function (FEV1/FVC) through Portable electronic spirometer in subjects with guillain- barre syndrome.

  • To evaluate the diaphragm muscle activity by EMG (ELECTROMYOGRAPHY) biofeedback in subjects with guillain- barre syndrome.


Respiratory intensive care unit, General ward, SVIMS, Tirupati, AP.


30 subjects who met inclusive criteria were selected by random sampling method and divided into experimental and control group. (15 in each group).


Diaphragm muscle activity is measured by surface EMG biofeedback; pulmonary function (FEV1/FVC) is measured with portable electronic spirometer. These parameters were assessed before intervention and on the seventh day after intervention.


The group treated with proprioceptive neuromuscular facilitation techniques (Rhythmic stabilisation, repeated contractions) and breathing exercises had significant improvement on diaphragm muscle function measured in mille seconds and FEV1/FVC compared to group treated without proprioceptive neuromuscular facilitation techniques.
