Cost-effectiveness analysis of robot-assisted gait training in patients with bilateral spastic cerebral palsy.

BACKGROUND: To date, there have been no published studies evaluating the cost-effectiveness of robot-assisted gait training (RAGT) in adolescent and adult patients with cerebral palsy (CP). The study´s aim was to analyse the cost-effectiveness of RAGT versus conventional kinesiotherapy (CON) from the health care provider's perspective. METHODS: We expressed the cost-effectiveness of RAGT in the Lokomat® system after analysing the costs and effects of RAGT and conventional therapy through the Incremental Cost-Effectiveness Ratio (ICER) based on a bicentric randomized controlled study, in which we demonstrated that the intensive RAGT regimen is more effective than conventional therapy in terms of improvements in gross motor functions in adolescent and adult patients with bilateral spastic CP. RESULTS: According to the calculated ICER ratio for Lokomat®, an additional improvement per unit of effect (1% in GMFM), compared to conventional therapy, results in an average cost increase of EUR70.38 per patient in a therapeutic block consisting of 20 TUs (Therapeutic Units). CONCLUSION: However, from the comprehensive analysis of the results and evaluation of the long-term effects, it follows that RAGT applied in adolescent and adult patients with bilateral spastic CP is not only more effective in terms of evaluation of monitored clinical parameters, but in the long term it is also more cost-effective compared to conventional therapy.

The effect of patient-specific factors on responsiveness to robot-assisted gait training in patients with bilateral spastic cerebral palsy.

BACKGROUND: No general recommendations are yet available for the application of robot-assisted treadmill therapy for children with cerebral palsy regarding the length and intensity of the intervention. OBJECTIVE: The aim of the study was to evaluate patient-specific determinants of responsiveness to robot-assisted gait training (RAGT) in patients with bilateral spastic cerebral palsy. METHOD: During 12 months, the patients underwent 1-4 blocks of RAGT, representing 16-82 TUs. The following parameters were evaluated before (V0) and after each therapeutic block (V1-V4): dimension A (lying and rolling), B (sitting), C (crawling and kneeling), D (standing), E (walking, running and jumping) of the Gross Motor Function Measure (GMFM-88). We evaluated the change in motor functions in relation to the severity of disability, age, gender and number of therapeutic units. RESULTS: Ninety-seven patients aged between 3.7 and 27 years (mean age 10.02 years (SD±5.29); Gross Motor Function Classification System level I [n = 5], II [n = 25], III [n = 48], IV [n = 19]) underwent 16-82 TUs (overall average number 34.06 TUs, SD±16.41) of RAGT. In the patient group, we recorded clinically meaningful improvement and statistically significant improvement (p < 0.001) in gross motor functions with gradual increase in the effect size after each therapeutic block. Using correlation and regression analysis, we found a statistically significant associations between the number of therapeutic units, severity of disability, and improvement in motor functions after RAGT. CONCLUSION: We have identified two determinants -the severity of disability and the number of therapeutic units -which could have a decisive and predictive character in setting rehabilitation/designing programmes. The duration of the applied RAGT period, frequency and intensity could be a crucial factor for the potential of improvement in children with BS-CP.

Effect of robot-assisted gait training on motor functions in adolescent and young adult patients with bilateral spastic cerebral palsy: A randomized controlled trial.

BACKGROUND: Robot-assisted gait training (RAGT) allows an intensive gait training in patients with cerebral palsy (CP). There are few evidences on the effectiveness of RAGT in adults with CP. OBJECTIVE: To assess the effect of RAGT on gross motor function in adolescent and adult patients with bilateral spastic CP and to compare the effect of RAGT with conventional kinesiotherapy. METHODS: Forty-seven patients (mean age 21.2±5.33 years) with bilateral spastic CP were divided into two groups. Twenty-one patients underwent 20 therapeutic units of RAGT and 26 patients underwent 20 therapeutic units of conventional therapy/training (CON). The following parameters were evaluated before (V1) and after the therapy (V2): dimension A (lying and rolling), B (sitting), C (crawling and kneeling), D (standing), E (walking, running and jumping) of the Gross Motor Function Measure (GMFM-88). In patients in the experimental RAGT group, these parameters were also evaluated 3-4 months later (V3). RESULTS: Comparing the mean improvements in endpoints in both groups (RAGT vs. CON) after 20 TUs, we observed the statistically significant difference (p < 0.001) and large effect size in all GMFM dimensions and total GMFM improvement in favour of the RAGT group. In RAGT patients, the improvement persisted even 3-4 months after RAGT (p < 0.001). CONCLUSION: We demonstrated that the intensive RAGT regimen is more effective than conventional therapy in terms of improvements in gross motor functions in adolescent and adult patients with bilateral spastic CP.
