Core Stabilization Exercise

Trunk stability exercises that focus on either deep or superficial muscles might produce different effects on lumbar segmental motion. This study compared outcomes in 34 lumbar instability patients in two exercises at 10 weeks and 12 months follow up. Participants were divided into either Core stabilization (deep) exercise, incorporating abdominal drawing-in maneuver technique (CSE with ADIM), or General strengthening (superficial) exercise (STE). Outcome measures were pain, muscle activation, and lumbar segmental motion. Participants in CSE with ADIM had significantly less pain than those in STE at 10 weeks. They showed significantly more improvement of abdominal muscle activity ratio than participants in STE at 10 weeks and 12 months follow-up. Participants in CSE with ADIM had significantly reduced sagittal translation at L4-L5 and L5-S1 compared with STE at 10 weeks. Participants in CSE with ADIM had significantly reduced sagittal translations at L4-L5 and L5-S1 compared with participants in STE at 10 weeks, whereas STE demonstrated significantly increased sagittal rotation at L4-L5. However, at 12 months follow-up, levels of lumbar sagittal translation were increased in both groups. CSE with ADIM which focuses on increasing deep trunk muscle activity can reduce lumbar segmental translation and should be recommended for lumbar instability.

Differential Timing

We assessed changes in respiratory muscle timing in response to hyperpnea and shortened inspiratory and expiratory times caused by chemoreceptor stimuli in six awake dogs. Durations of postinspiratory inspiratory activity of costal and crural diaphragm (PIIA), the delay in diaphragm electromyogram (EMG) after the initiation of inspiratory airflow, postexpiratory expiratory activity of the transversus abdominis (PEEA), and the delay of abdominal expiratory muscle activity after the initiation of expiratory airflow were measured. In control, four out of six dogs showed PIIA [8–10% of expiratory time (TE)]; all showed delay of diaphragm [19% of inspiratory time (TI)], delay of abdominal muscle activation (21% of TE), and PEEA (24% of TI). Hypercapnia decreased PIIA (4–9% of TE), maintained diaphragm delay at near control values (23% of TI), increased PEEA (36% of TI), eliminated delay of abdominal muscle activation (4% of TE), and decreased end-expiratory lung volume (EELV). Hypocapnic hypoxia increased PIIA (24–25% of TE), eliminated diaphragm delay (3% of TI), eliminated PEEA (3% of TI), reduced delay of abdominal muscle activation (14% of TE), and increased EELV. Most of these effects of hypoxic hypocapnia vs. hypercapnia on the within-breath EMG timing parameters corresponded to differences in the magnitude of expiratory muscle activation. These changes exerted significant influences on flow rates and EELV.
