Brief Summary

Background: Respiratory disease is one of the main causes of morbidity and mortality in adults with cerebral palsy (CP). Adequate pulmonary function is essential to prevent these health problems, however respiratory muscle training has not yet been studied in CP patients. The main objective of the study was to investigate the maintenance over time of improvements in respiratory parameters achieved with inspiratory muscle training (IMT). Methods: This was a controlled, randomised, double-blind trial and with allocation concealment performed on 27 institutionalized CP patients randomly distributed in 2 groups, "high intensity training group" (HIT) and "low intensity training group" (LIT). Participants followed a specific IMT program for 8 weeks, HIT workload was 40% of maximum inspiratory pressure (MIP) and LIT workload was 20% MIP. Once finished 8-week training period, CP patients continued their daily activities. Respiratory muscle strength and pulmonary function were measured pre-IMT, post-IMT, 4, 12 and 24 weeks after finishing IMT.

Conditions

Outcome Measures

Primary Outcomes (1)

  • Inspiratory muscle strength

    Maximum inspiratory pressure (MIP), unit of measure, Centimeters of water (cmH2O).

    8 weeks.

Secondary Outcomes (3)

  • Expiratory muscle strength

    8 WEEKS

  • Respiratory volume

    8 Weeks

  • Respiratory flow

    8 weeks.

Study Arms (2)

The High Intensity Training Group (HIT)

EXPERIMENTAL

The High Intensity Training Group (HIT) received IMT at 40% of Maximum Inspiratory Pressure (MIP), the training load was set each 2 weeks to keep 40% of MIP.

Device: INSPIRATORY MUSCLE TRAINING

The Low Intensity Training Group (LIT)

EXPERIMENTAL

The Low Intensity Training Group (LIT) received IMT at 20% of MIP, following the same rules as HIT.

Device: INSPIRATORY MUSCLE TRAINING

Interventions

After finishing the 8-week intervention period with IMT, CP patients stopped training with IMT and continued with their daily normal activities. During the following 24 weeks (without IMT), three evaluations of the respiratory parameters analyzed in the trial were made (MIP, MEP, FEV1, PEF). The first evaluation was made 4 weeks after the intervention was completed, the second 12 weeks and the third 24 weeks after finishing IMT.
