Email: borji-rihab1@hotmail.fr Background: This study aimed to compare the effecveness of a hopping and jumping training programme (HJP) versus a sensorimotor rehabilitaon programme (SRP) on postural performances in children with intellectual disability. Methods: Three groups of children with intellectual disability parcipated in the study: the HJP group, the SRP group and a control group. Postural capacies were tested with the Berg Balance Scale (BBS) and the Tine tests. The HJP and the SRP groups parcipated in the training programmes for eight weeks. Then, all parcipants were retested. Results: Results showed that before the training period, there are no significant differ- ences between the three groups. Aſter the training period, the BBS and the Tine scores increased significantly in the HJP group and the SRP group with greater extent in the HJP group than in the STP group. Conclusion: We suggest that HJP training is more recommended to improve postural capacies in children with intellectual disability.

Studies showed this postural control impairment was due to slowing down equivalent reacons (Cimolin et al., 2011; Galli et al., 2008) as well as disorders in vesbular (Cabeza-Ruiz et al., 2005) and somato- sensory (Suomi & Koceja, 1994; Webber, Virji-Babul, Edwards, & Lesperance, 2004) funcons. Because the visual input is one of the most important input systems to postural control (Ledin & Odkvist, 1991), the visual and perceptual impairments accompanying intellec- tual disability could be responsible for their postural impairment (Hale, Miller, Barach, Skinner, & Gray, 2009; Hale et al., 2007). Moreover, muscular funcon plays a primary role in postural control (Horak, 2006). Therefore, the muscle weakness and dysfuncon reported in individuals with intellectual disability (Borji, Sahli, Zarrouk, Zghal, & Rebai, 2013; Borji, Zghal, Zarrouk, Sahli, & Rebai, 2014) could also explain this postural impairment. In individuals with intellectual disability, balance improvement is considered to be very important in improving their independency and decreasing the high risk of fall and fall-related injuries (Cox, Clemson, Stancliffe, Durvasula, & Sherrington, 2010) associated with a sedentary lifestyle (Finlayson et al., 2009). Postural capacies’ improvements aſter physical acvies have been shown to result from acng on the bal- ance sensors or on the motor responses (Perrin, Deviterne, Hugel, & Perrot, 2002; Wolfson et al., 1996). Different training programmes have been suggested to improve postural capacies in these individuals. A postural balance improvement was found aſter 12 weeks of a rhythmic
