Relationships between lower extremity strength and the multi-directional reach test in children aged 7 to 12 years

Effect of core stabilization versus rebound therapy on balance in children with cerebral palsy

OBJECTIVE

This study aimed to compare the effect of core stabilization exercises and rebound therapy on balance in children with hemiplegic cerebral palsy (CP).

METHODS

Fifty- two children of spastic hemiplegic CP aged 5 up to 8 years from both genders were assigned randomly into two groups: core stability and rebound therapy groups. Both groups received 3 sessions/week, 1.5-h training per session, for 12 successive weeks. The measurement was performed at baseline and post-treatment. Balance as a primary outcome for this study was measured by a Biodex Balance System (BBS), and knee extensor strength and functional capacity as secondary outcomes were assessed using a hand-held dynamometer, and a six-minute walk test (6MWT), respectively.

RESULTS

All variables showed a significant improvement after intervention in each group (p < 0.0001), with significant improvement in all stability indices (overall, anteroposterior, and mediolateral) in core stability group when compared to rebound therapy group.

CONCLUSION

Core stability exercises and rebound therapy are recommended in the rehabilitation of children with hemiplegic CP. Core stability exercises were more effective than rebound therapy for balance improvement.

The multi-directional reach test in children with Down syndrome

Objective:

This study investigated the limits of stability (LOS) and the movement patterns during reaching by applying the Multi-Directional Reach Test (MDRT) in children with Down syndrome (DS) aged 7–12 years old.

Methods:

Thirty children with DS and 30 age and gender typical development (TD) matched children, aged 7–12 years old were recruited. Each child was asked to reach as far as possible during standing in four directions using a self-selected movement pattern. The movement patterns were classified by two experienced pediatric physical therapists.

Results:

The reach distance in children with DS aged 7–9 years old was significantly shorter than TD children aged 7–9 years old for the forward and backward directions. Also, the reach distance in DS children aged 7–9 years old was significantly smaller than that of TD children aged 10–12 years old for all directions. For children with DS aged 10–12 years old, the reach distance was significantly less than that of TD children only in the backward direction. All children with DS in this study adopt a hip and mixed strategy during forward and backward reaching. In contrast, TD children adopt an adult-like movement pattern.

Conclusion:

The boundary of stability in an anteroposterior (AP) direction of children with DS aged 7–12 years old was lesser than the matched TD children, especially for the backward direction. These findings may assist therapists in detecting postural control and balance problems in children with DS.

Evaluating the validity of diagnostic methods for scoliotic posture of primary school children

Primary school children are exposed to asymmetric loads that lead to an imbalance of postural muscles and a violation of the body relative symmetry. Mass screening examinations in schools for scoliotic posture and scoliosis are conducted primarily through the Adams test. It has low reproducibility and a high frequency of false negative results. In practice, various methods for diagnosing posture disorders are also used. Some methods are based on the evaluation of postural muscles static endurance, elasticity and proportionality of their functional capabilities. Others are based on a comprehensive assessment of the ability to maintain an upright posture rationally. The third ones are based on the analysis of the tonic vibration and H-reflex of skeletal muscles on both sides of the vertebral column. All the above mentioned methods definitely have diagnostic potential. Therefore it was decided to determine the validity of some common methods for diagnosing posture disorders based on the analysis of their mutual congruence. Based on the results of the experiment, a reliable correlation between the studied parameters was established. It in turn allows us to judge the congruence of the considered diagnostic methods and, accordingly, the high probability of their validity.
