Effects of Lumbar Stabilization Exercise on Postural Sway of Patients with Adolescent Idiopathic Scoliosis during Quiet Sitting

Due to balance deficits that accompany adolescent idiopathic scoliosis (AIS), the potential interaction between activities of daily living and active self-correction movements (ASC) on postural control deserves particular attention. Our purpose was to assess the effects of ASC movements with or without a secondary mental task on postural control in twenty-five girls with AIS. It is a quasi-experimental within-subject design with repeated measures ANOVA. They were measured in four 20-s quiet standing trials on a force plate: no task, ASC, Stroop test, and both. Based on the center-of-pressure (COP) recordings, the COP parameters were computed. The ASC alone had no effect on any of the postural sway measures. Stroop test alone decreased COP speed and increased COP entropy. Performing the ASC movements and Stroop test together increased the COP speed and decreased COP entropy as compared to the baseline data. In conclusion, our results indicate that AIS did not interfere with postural control. The effects of the Stroop test accounted for good capacity of subjects with AIS to take advantage of distracting attentional resources from the posture. However, performing both tasks together exhibited some deficits in postural control, which may suggest the need for therapeutic consultation while engaging in more demanding activities.

Core Stabilization Exercise

Background: There are several kinds of scoliosis-specific and general physiotherapeutic exercise methods used in scoliosis rehabilitation. But there is need for comparable studies on the effectiveness of different exercise approaches for the treatment of adolescent idiopathic scoliosis. Objectives: Comparison of the effects of combined core stabilization exercise and bracing treatment with Scientific Exercises Approach to Scoliosis and bracing treatment in patients with moderate adolescent idiopathic scoliosis. Methods: Thirty females with adolescent idiopathic scoliosis, who have moderate curves (20°–45°), were randomly divided into two groups. In addition to brace wearing for 4 months, one group received core stabilization exercise therapy, while the other received scientific exercises approach to scoliosis exercise therapy. The outcome measures were based on Cobb angle, angle of trunk rotation, body symmetry, cosmetic trunk deformity, and quality of life. Results: Thoracic and lumbar Cobb angles and trunk rotation angles, body symmetry, and cosmetic trunk deformity improved for both groups. Quality of life did not change in either group. The pain domain of the Scoliosis Research Society-22 questionnaire improved in the core stabilization group only. Conclusion: Both treatment conditions including core stabilization with bracing and scientific exercises approach to scoliosis with bracing had similar effects in the short-term treatment of moderate adolescent idiopathic scoliosis. Clinical relevance This study showed that when scientific exercises approach to scoliosis (SEAS) and core stabilization (CS) exercises were administered with equal intensity, the effects of the two treatment protocols including CS and bracing and SEAS and bracing were similar in the treatment of patients with moderate adolescent idiopathic scoliosis (AIS).

Adolescent idiopathic scoliosis (AIS) has been postulated to affect gait patterns and postural stability due to its effect on center of body mass. 1) Determine the correlation between Cobb angle and COP in the anterior-posterior (AP) direction, COP in the medial-lateral (ML) direction, COP oscillation (COP-O) from midline walking, peak pressures, and pressure-time integrals (loading) at 10 anatomic foot segments; 2) Determine the differences in COP-AP, COP-ML, COP-O, and peak plantar pressures at 10 anatomic foot segments between the normal group and the AIS group. All patients wore a gown to expose the posterior trunk and underwent evaluation with Formetric 4D (DIERS International GmbH, Schlangenbad, Germany) while walking on the treadmill at 2 km/hour for 15 seconds. A total of 24 pressure metrics at 10 anatomic foot segments were evaluated. We then analyzed the data using t-test and linear regression analyses.16 patients were assigned to a normal group (Cobb angle 10° or less, n=4) or AIS group (Cobb greater than 10°, n=12). Of note, AIS patients had statistically significant lower max. pressures at the hallux and the 2nd, 4th, 5th metatarsal head compared to the normal group. Additionally, there was a statistically significant linear association between Cobb angle and both hallux max. pressure and hallux pressure-time integral (P<0.05). Reduced peak plantar pressures before the toe-off phase of gait cycle indicate that AIS patients may lean backwards and have posterior postural sway, which may be associated with hypokyphosis during walking.
