The effect of an exercise regime on Lumbar Spine Curve

Subjects receiving exercises demonstrated reduction in the LSC in the standing position. The significant difference was in the LSC of the experiment group (F= 9.57). The amount of the LSC in the control group was not significantly different. These findings may support the idea that the frequent repetition of careful exercise with control and with constant orientation changes the habitual postural pattern (Goldthwait et al, 1952, Hawely, 1949, Kelly, 1965; Mensedick, 1937; Rathbone and Hunt, 1965; cited by Luttages and Wells 1982) Flexibility is an important component of good posture. In fact maintenance of flexibility is an essential part of lumbar spine curve re-education We used an active self-stretching technique (Kisner and Colby 1990) to improve the flexibility for the lumbar erector spine and iliopsoas muscles. The subjects carried out exercise himself by his body weight. The results indicated that there was no significant difference in the experiment group’s LF however, they showed some improvement in the LF flexibility (from 6.34 cm increased to 6.64 cm).
Static stretching time required to reduce iliacus muscle stiffness

The iliopsoas muscle consists of the iliacus and psoas major muscles. The iliacus muscle has greater physiological cross-sectional area (PCSA) and hip flexion moment arm than the psoas major muscle (Blemker & Delp, 2005; Klein Horsman, Koopman, van der Helm, Prosé, & Veeger, 2007). Therefore, increased stiffness or shortening of the iliacus muscle affects hip extension ROM more strongly than similar changes in the psoas major muscle.
