RESUMEN
Equine Facilitated Physical Therapy (EFPT) lacks consistent documentation due to being an unconventional physical therapy treatment to chronic low back pain patients (LBP) and lacking rehabilitation outcome measure tools for a stable (equestrian) environment. The objectives were to develop an online evaluation tool as well as to define inter- and intra-rater reliability to validate the outcome measurement tool "Evaluation of maintaining sitting position (on a horse) and walking (short distances)" designed for LBP patients in EFPT". A total of 48 movement related functions (n = 48), were derived from the International Classification of Functioning (ICF) and organized to an online evaluation tool. Depending on the state of validation two to six (2-6) raters scored randomized patient (n = 22) video material, recorded during a 12-week EFPT intervention, with the designed tool. Inter-rater agreement level between the experts reached good (α = 87) reliability for the scoring of the items and calculated per patient excellent (α = 100). Intra-rater reliability reached good (α = 87) and per patient good (α = 80) repeatability. For the healthy adults the reliability between raters reached acceptable (α = 72) levels and per rated excellent (α = 100). The developed assessment tool was found satisfactory to fulfil the requirement for the therapeutic practice. With the use of the tool physical therapist may detect postural changes for LBP patients as outcome report in EFPT. The tool may be used to identify treatment progress and to help design home exercises. The created tool will help to collect similar outcome measures from LBP patients in EFPT and to validate the treatment within industry.
