is disturbed. Several studies examining the biomechanics of sitting posture also found that postural constraints, such as spine angles and footrest status, can affect sitting balance ( Andersson, Ortengren, Nachemso, & Elfström, 1974 ; Bolin, Bodin, & Kreuter, 2000 ; Harrison, Harrison, Croft

A novel test instrument was designed to objectively quantify the progress of persons who participated in therapeutic horseback riding programs. Nineteen handicapped children, ages 7 to 14 years, with heterogeneous impairments were evaluated before and after riding. For measures of sitting balance and coordination, and hand, hip, knee, and ankle strength, marked improvements were noted for most children. Clinical impressions of therapists and parents suggested concomitant progress in characteristics such as self-confidence and interaction with others. Results from this pilot study appeared to support the use of the apparatus in that field setting.

Objective:

To compare classification levels and trunk stabilization of wheelchair basketball players and to identify their norm values of trunk balance.

Participants:

113 wheelchair basketball players in the super and first Turkish leagues.

Interventions:

A modified Wheelchair Skills Test (WST) (version 4.1) was used to evaluate trunk stabilization. Two skills were chosen that correspond to the stationary wheelie activity in WST, the 30-s stationary wheelie and stationary wheelie in 180°.

Main Outcome Measure:

There are no statistical differences between WST rates and point means.

Results:

The skills and success and safety rates of the players with 1.5 points (51.9%, 44.4%) were lower than those of the players with 1.0 point (70%, 66.7%). In players with 2.5 and 2.0 points, the most successful and safest percentage values were 78.6%, 78.6% and 82.1%, 75%.

Conclusions:

Although it is expected that trunk stabilization would be better in players with high points, in our study we encountered conflicting results between the points and sitting balance or trunk stabilization. Our study supports the studies in the literature suggesting modifications in the functional-classification system.

Many of the exercises involved in the examined studies are commonly used by athletic trainers to improve balance and proprioception for a multitude of lower extremity injuries. There are five main categories of vestibular exercises: (a) eye-head coordination, (b) sitting

An alternative method for assessing trunk stability during a sitting balance task is to evaluate reactions to perturbations of the center of pressure ( Hendershot
