Brief Summary:
Cerebral Palsy (CP) describes a group of chronic conditions affecting body movement and muscle coordination caused by damage to one or more areas of the brain, usually occurring during fetal development or infancy. One of the most disabling mobility impairments in CP is gait impairment, clinically characterized by reduced speed and endurance, as well as reduced step, stride length and toe clearance during gait.
Recently, gait rehabilitation methods in patients with neurological impairment have relied on technological devices, which drive the patient's gait in a body-weight support condition and emphasize the beneficial role of repetitive practice. Early studies in gait rehabilitation in patients with CP were carried out by using partial body-weight support treadmill training (PBWSTT) and robotic-assisted treadmill therapy. Despite their potential, these technologies have practical limitations in their routine application.
More recently, several studies have focused on the use of a new electromechanical gait trainer (Gait Trainer GT I; Reha-Stim, Berlin, Germany) in adult patients who have experienced a stroke. They have shown that training with this device may significantly improve gait performance. Despite the clinical impact of this new rehabilitative procedure, to date, no studies have been conducted on its use in children with CP.

Detailed Description:
Cerebral Palsy (CP) describes a group of chronic conditions affecting body movement and muscle coordination caused by damage to one or more areas of the brain, usually occurring during fetal development or infancy. The motor disorders of CP are often accompanied by disturbances of sensation, cognition, communication, perception, behavior, and/or a seizure disorder. One of the most disabling mobility impairments in CP is gait impairment, clinically characterized by reduced speed and endurance, as well as reduced step, stride length and toe clearance during gait.
Recently, gait rehabilitation methods in patients with neurological impairment have relied on technological devices, which drive the patient's gait in a body-weight support condition and emphasize the beneficial role of repetitive practice. The rationale for these approaches originates from animal studies which have shown that repetition of gait movements may enhance spinal and supraspinal locomotor circuit.
Early studies in gait rehabilitation in patients with CP were carried out by using partial body-weight support treadmill training (PBWSTT) and robotic-assisted treadmill therapy. The majority of these studies consisted of single case, small or unselected patient samples and/or uncontrolled trials. In a recent randomized control trial study, Willoughby et al. showed that PBWSTT was no more effective than overground walking for improving walking speed and endurance in children with CP. They concluded that the progressive reduction of body weight support along with adding concurrent overground walking practice to a treadmill training protocol may increase the intensity of training and assist with carry over of improvements to overground walking. Despite their potential, these technologies have practical limitations in their routine application: PBWSTT requires the assistance of one or two physiotherapists to control the patient's weight shift and lower limb position during training and proper placement of the patient onto the machine (Lokomat, Hokoma Inc., Volketswill, Switzerland) for robotic-assisted treadmill training is time-consuming.
More recently, several studies have focused on the use of a new electromechanical gait trainer (Gait Trainer GT I; Reha-Stim, Berlin, Germany) in adult patients who have experienced a stroke. They have shown that training with this device may significantly improve gait performance. Despite the clinical impact of this new rehabilitative procedure, to date, no studies have been conducted on its use in children with CP.
The primary aim of the present randomized controlled trial is to evaluate whether repetitive locomotor training with the Gait Trainer GT I can improve endurance in tetra- or diplegic ambulatory children with CP. The secondary aim was to assess whether training can also have a positive impact on spatiotemporal gait parameters and quality of life.
Study Design Randomised controlled, blinded clinical trial.
Materials and methods Twenty CP patients will be enrolled in the study. The inclusion criteria will be: bilateral lower limb (diplegic or tetraplegic) CP, 10 to 18 years of age, GMFCS levels II to IV, walk by themselves or with the use of an assistance device for at least 10 meters, maintain a sitting position without assistance and follow instructions and participate in the rehabilitative program. The exclusion criteria will be: lower limb spasticity \>2 on the Modified Ashworth Scale, severe lower limb contractures, cardiovascular diseases, orthopedic surgery or neurosurgery in the past 12 months or Botulinum toxin and injections within 6 months before the beginning of the study.
At the moment of recruitment (before treatment), at the end of treatment (6 weeks) and one month and two months after the end of the treatment (FU) each patient will be tested with the following clinical and instrumental procedures. Clinical assessment procedures: 6-minute Walking Test, Ten Meter Walking Test, Gross Motor Classification System, Child Health Questionnaire (CHQ-PF50) Italian version, Wee FIM and Energy Expenditure Index. Instrumental assessment procedures: Gait analysis by means of GAITRite® System and measure of energy cost by COSMED K4b2.
As primary outcome measure will be considered the 6-minute Walking Distance Test. As secondary outcomes measures will be considered Ten Meter Walking Test, Gross Motor Classification System, Child Health Questionnaire (CHQ-PF50) Italian version, Wee FIM and Energy Expenditure Index, Spatio-temporal parameter with GAITRite® System and measure of energy cost by COSMED K4b2. The allocation in the two groups will be done with simple randomisation.
Patients will be randomized into two groups. The first group (experimental group) will be subjected to 12 treatment session (3 sessions/week) on Gait Trainer machine for one month. The second group (control group) will undergo to a conventional treatment with the same duration and frequency of the experimental group. Data will be analysed by means parametric and non-parametric tests. Both, within and between groups comparison will be performed. Data will be analyzed using SPSS software (ver 11.0; SPSS Inc., Chicago, IL, USA).
