Parents' views of the efficacy of conductive education in Sweden

Parents of children who have participated in a conductive education programme in Sweden were asked questions about their reasons for choosing the programme, the expectations they had of it and how they were fulfilled. The results showed that the parents were satisfied with the development of their child, and wanted to continue to take part in further courses with their child. They appreciated the intensive training and found it motivating and enjoyable for the child. They wanted an intensive training for their child because they believed that active training could help the child to develop. The parents learned more about cerebral palsy at the courses and now understood why and how they could train their child. Most of the parents continued the training at home with the child. They experienced financial difficulties in participating in further courses, and found it difficult to stay away from work and family for a long period of time.     

Effects of blood flow restriction without additional exercise on strength reductions and muscular atrophy following immobilization:A systematic review

Purpose:To investigate whether blood flow restriction(BFR) without concomitant exercise mitigated strength reduction and atrophy of thigh muscles in subjects under immobilization for lower limbs.Methods:The following databases were searched:PubMed,CINAHL,PEDro,Web of Science,Central,and Scopus.Results:The search identified 3 eligible studies,and the total sample in the identified studies consisted of 38 participants.Isokinetic and isometric torque of the knee flexors and extensors was examined in 2 studies.Cross-sectional area of thigh muscles was evaluated in 1 study,and thigh girth was measured in 2 studies.The BFR protocol was 5 sets of 5 min of occlusion and 3 min of free flow,twice daily for approximately 2 weeks.As a whole,the included studies indicate that BFR without exercise is able to minimize strength reduction and muscular atrophy after immobilization.It is crucial to emphasize,however,that the included studies showed a high risk of bias,especially regarding allocation concealment,blinding of outcome assessment,intention-to-treat analyses,and group similarity at baseline.Conclusion:Although potentially useful,the high risk of bias presented by original stodies limits the indication of BFR without concomitant exercise as an effective countermeasure against strength reduction and atrophy mediated by immobilization.
