Reliability and concurrent validity of the step quick turn test in older persons with a unilateral transtibial amputation.
ABSTRACT This study aimed to investigate the reliability and validity of the Step Quick Turn Test in older transtibial amputees.
Fifteen male and female transtibial amputees repeated the timed "up and go" test and the Step Quick Turn Test measures of turn time (TT) and turn sway (TS) each to the prosthetic and sound side, approximately 2 wks apart.
The intraclass correlation coefficients (2,1) for TT and TS were excellent (≥ 0.85). Spearman rank correlation coefficients between the timed "up and go" test and the TT of turning to each side and TS on the prosthetic side were excellent (≥ 0.75), whereas that for the TS to the sound side was fair to good (0.58).
The TT and TS demonstrate an acceptable reliability for individual use in a clinical setting with the exception of TT to the prosthetic side. Differences in validity between the prosthetic and sound sides were also identified, with TT demonstrating excellent validity against the timed "up and go" test for both sides, whereas the TS was weaker when evaluated toward the sound side.

ABSTRACT: Background and aim:Turning is an inherent problem in all lower limb amputees and more so in older dysvascular amputees. This study aimed to compare the turning performance of dysvascular amputees with that of the traumatic amputees.Technique:Six dysvascular transtibial amputees (69.83 ± 6.3 years) and six traumatic transtibial amputees (68.3 ± 6.6 years) completed the Step Quick Turn test of the NeuroCom(®) Balance Master and the Timed Up and Go Test. The measures used for comparison were as follows: turn time and turn sway of Step Quick Turn test, turning 180° to both the prosthetic and sound side and time taken to complete the Timed Up and Go Test.Discussion:The Mann-Whitney U test demonstrated a significant difference (p < 0.05) between the dysvascular and traumatic groups in turn sway to the prosthetic (70.7 ± 14.2 and 43.3 ± 9.7) and sound sides (72.5 ± 16.1 and 43.5 ± 8.2). Similar results were observed in turn time to the prosthetic (4.1 ± 1.4 and 1.7 ± 0.46) and sound sides (4.0 ± 1.3 and 2.1 ± 0.5). No significant difference was observed for the Timed Up and Go Test.Clinical relevanceThe observed differences suggest that dysvascular amputees are less able to adapt to the challenges associated with turning. More attention is required in the rehabilitation of dysvascular amputees in turning tasks particularly towards the prosthetic side.Prosthetics & Orthotics International 04/2013; · 0.56 Impact Factor

ABSTRACT: Objective. This study aimed to evaluate the effect of a long-period multimodal exercise program on balance, mobility and clinical status of patients with Parkinson’s disease (PD). Methods. Thirty-three PD patients were assigned into two groups: a training group ( T G - - - 𝑛 = 2 2 ; aged 6 7 . 2 3 ± 8 . 3 9 years) and a control group ( C G - - - 𝑛 = 9 ; aged 7 1 . 5 6 ± 8 . 5 0 years). The TG patients were enrolled in a 6-month multimodal exercise program. This program was designed to improve physical capacity components and to reduce PD impairments. Balance and mobility were assessed immediately before and after the training protocol using the Berg Balance Scale (BBS), the “Timed up and go” (TUG), and the Posture Locomotion Test (PLM). Also, clinical variables were assessed (disease stage and impairments). Results. The TG showed an improvement in the TUG ( 𝑃 = 0 . 0 0 6 ) while CG were not influenced by the 6-months period. Both groups showed no differences for BBS and PLM and for their disease impairments—assessed through the Unified Parkinson’s disease Scale. Conclusions. Long-term multimodal exercise programs are able to improve mobility of patients with Parkinson’s disease and therefore should be used on clinical day life.ISRN Rehabilitation. 01/2012; 2012:7 pages.
