Star Excursion Balance Test in Young Athletes with Back Pain

The reliability and validity of the balance tests in hearing-impaired athletes

BACKGROUND

It is known that balance is affected in hearing-impaired athletes and its effects on performance. However, studies on the reliability and validity of scales evaluating balance are insufficient.

AIM

To analyze and demonstrate the effectiveness of various clinical tests using assessment balance for hearing-impaired athletes.

METHOD

The study included 60 elite athletes (aged between 18 and 25) with (n = 30) and without (n = 30) hearing impairment. The static balance was evaluated with the Flamingo Test (FT) and the dynamic balance with the Functional Reach Test (FRT), Four-Step Square Test (FSST), Star Excursion Balance Test (SEBT), and Y Balance Test (YBT). All balance tests were repeated at 1-week intervals. Test-retest reliability, known-group validity, and predictive validity of the scales were investigated.

RESULT

All balancing tests demonstrated strong test-retest reliability. FT and FSST had known-group and predictive validity. While FRT and the components of both YBT and SEBT involving anterior reaching were not valid tests for hearing-impaired individuals, YBT and SEBT had validity considering the composite score and other components.

CONCLUSION

It was revealed that the balance of hearing-impaired athletes was comparable to the balance of healthy athletes in test conditions in which visual information could be used effectively. For this reason, it is important to consider the visual information factor when evaluating the balance of hearing-impaired athletes. Additionally, taking into account time and tiredness, FT for static balance and FSST for dynamic balance may be helpful to evaluate hearing-impaired athletes.

Developing the Temporal and Order Characteristics of a Dance-Specific Star Excursion Balance Test (dsSEBT)

BACKGROUND

Previous studies have made crucial steps toward developing a dance-specific balance test to challenge dancer's balance capabilities wherein positional characteristics, timing, as well as reach order were altered. However, the authentic performance nature of the protocols could be questioned.

PURPOSE

The aim of this study was to examine the effects of different tempo and order variations on the previously developed Dance-Specific Star Excursion Balance Test (dsSEBT).

METHODS

Twenty- two female dancers voluntarily took part in the research (162.68 ± 6.57 cm; 61.35 ± 11.25 kg). This research looked at 3 different temporal variations as well as an alternate reach order, to the traditional order, to examine the effect it may have on individual spoke scores. Reach distances (% of limb length), center of pressure (cm2), and error scores were measured.

RESULTS

Overall, the varying tempos did not create a significant change in any of the variables measured (P = .067-1.00) which suggests that dancers have a unique ability to adapt to temporal changes due to the nature of ever-changing tempos in class and performance. Additionally, the new reach order did not affect the difficulty level of each individual spoke, which agrees with previous research suggesting that the crossed side and crossed front spokes are in fact the most challenging spokes for ballet and contemporary dancers to accomplish.

CONCLUSION

Results support the utilization of all 8 spokes of the dsSEBT in identifying balance deficits in this genre of dancers. The data collected in this study provides useful baseline measurements to further develop a reliable dance-specific dynamic balance test protocol to be used by ballet and contemporary dancers.

Star Excursion Balance Test as a Predictor of Musculoskeletal Injury and Lower Back Pain in Non-Professional Soccer Players

Soccer is a sport with worldwide popularity but has a substantial risk of injury. Clinical screening tools are an important factor in strategies of injury prevention. The purpose of the study was to examine the relationship between the Star Excursion Balance Test (SEBT) and injury and lower back pain (LBP) in amateur soccer players. The research was performed as a longitudinal cohort study on 42 amateur male soccer players with 15.8 ± 6.6 years of soccer playing (age: 25.5 ± 6 years). Participants were surveyed with regard to their soccer playing, injuries, and LBP, and the SEBT was performed. They were followed for 3.5 months. At the follow-up, an additional set of data regarding injuries and LBP was gathered. Significant differences were found in all directions and in the composite score of the SEBT between uninjured and injured players. Shorter distance in all directions and a lower composite score were associated with injury in general. Shorter distances in all but the anterior direction and a lower composite score were associated with lower extremity injury, and shorter anterior distance was associated with LBP. Amateur soccer players with lower SEBT scores are more prone to injuries in general, as well as injuries of the lower extremities. SEBT presents as a useful clinical screening tool in identifying amateur soccer players at risk of injury.

Deficits in the Star Excursion Balance Test and Golf Performance in Elite Golfers with Chronic Low Back Pain

The purpose of this study was to investigate whether low-handicap elite golfers with chronic low back pain (CLBP) exhibit deficits in dynamic postural control and whether CLBP affects golfers in terms of their golf swing parameters. A total of fifteen Division 1 college golfers were recruited as participants. Of these, six of whom experienced CLBP, while the remaining participants were healthy. In this study, CLBP was defined as experiencing chronic pain symptoms for more than six months. The Star Excursion Balance Test (SEBT) was administered to examine dynamic posture control in both groups. The TrackMan Golf Launch Monitor Simulator was used to collect data on the performance parameters of the swing of the participants. The results for both feet in the medial, lateral, posterior, posteromedial, and posterolateral directions indicated that the CLBP group scored lower than the control group. However, the CLBP group scored higher for the right foot in the anterolateral direction. The parameters for the club speed and ball carry of the CLBP group were lower than those of the control group. Further, the CLBP group exhibited a more upright swing plane relative to the control group. Taken together, our findings suggest that SEBT may be feasible and highly accessible to assess golf swing performance of elite players with CLBP.

Non-specific chronic low back pain and physical activity: A comparison of postural control and hip muscle isometric strength: A cross-sectional study

Most research on sedentary lifestyle has focused on pain and disability, while neuromuscular outcomes (postural control and strength) have received less attention. The objective of the study was to determine whether low level of physical activity is negatively associated with measures of lower body muscular strength and postural control in individuals with and without non-specific chronic low back pain (NSCLBP).Twenty-four subjects with NSCLBP (28.8 ± 5.9 years) and 24 age, gender, and body mass index matched healthy controls participated in the study. Subjects were sub-classified into 4 subgroups based on their physical activity level: Non-active NSCLBP; Active NSCLBP; Non-active healthy control; and Active healthy control. Each subgroup consisted of 12 subjects. Peak force of hip muscles strength was assessed using a handheld dynamometer. Postural control was assessed using computerized posturography and the Y Balance Test.There was no significant group by physical activity interaction for strength and static and dynamic postural control, except for static control during left single leg stance with eyes closed (P = .029). However, there was a significant difference in strength and postural control by physical activity (P < .05). Postural control and peak force of hip muscles strength were significantly associated with physical activity (r ranged from 0.50 to 0.66, P < .001 and r ranged from 0.40 to 0.59, P < .05, respectively).Postural control and hip strength were independently related to physical activity behavior. A sedentary behavior may be an important risk factor for impaired postural control and hip muscles strength, and that physical fitness is vital to neuromuscular outcomes.

Reproducibility of Static and Dynamic Postural Control Measurement in Adolescent Athletes with Back Pain

Static (one-legged stance) and dynamic (star excursion balance) postural control tests were performed by 14 adolescent athletes with and 17 without back pain to determine reproducibility. The total displacement, mediolateral and anterior-posterior displacements of the centre of pressure in mm for the static, and the normalized and composite reach distances for the dynamic tests were analysed. Intraclass correlation coefficients, 95% confidence intervals, and a Bland-Altman analysis were calculated for reproducibility. Intraclass correlation coefficients for subjects with (0.54 to 0.65), (0.61 to 0.69) and without (0.45 to 0.49), (0.52 to 0.60) back pain were obtained on the static test for right and left legs, respectively. Likewise, (0.79 to 0.88), (0.75 to 0.93) for subjects with and (0.61 to 0.82), (0.60 to 0.85) for those without back pain were obtained on the dynamic test for the right and left legs, respectively. Systematic bias was not observed between test and retest of subjects on both static and dynamic tests. The one-legged stance and star excursion balance tests have fair to excellent reliabilities on measures of postural control in adolescent athletes with and without back pain. They can be used as measures of postural control in adolescent athletes with and without back pain.
