The state of research into gene and cell therapy for cardiac issues in FRDA is one that deserves cautious optimism. As these therapies move closer to testing in humans, researchers will need to identify proper dosing and delivery methods based on the nature of the patient’s disease, as well as which patient groups are most likely to realize benefits from proposed treatments. Future studies must further assess risk in larger animals and plan ways to minimize risk in human trials.

Effect of power-assisted hand-rim wheelchair propulsion on shoulder load in experienced wheelchair users: A pilot study with an instrumented wheelchair
Marieke G.M. Kloosterman, Jaap H. Buurke, Wiebe de Vries, Lucas H.V. Van der Woude, Johan S. Rietman, Medical Engineering & Physics, Available online 22 August 2015, ISSN 1350-4533, http://dx.doi.org/10.1016/j.medengphy.2015.07.004.
According to the guidelines, in order to create a better balance between mechanical loading and the work-capacity of the shoulder complex during propulsion, power-assisted propulsion on a treadmill is effective in reducing the majority of the potential risk factors of shoulder injury. Therefore, the use of power-assisted wheelchairs might be indicated for subjects prone to developing overuse injuries due to hand-rim propulsion or subjects with difficulties driving a hand-rim wheelchair primarily due to lack of upper-extremity power.

Friedreich ataxia in Norway – an epidemiological, molecular and clinical study
Iselin Marie Wedding, Mette Kroken, Sandra Pilar Henriksen, Kaja Kristine Selmer, Torunn Fiskerstrand, Per Morten Knappskog, Tone Berge and Chantal ME Tallaksen; Orphanet Journal of Rare Diseases 2015, 10:108 doi:10.1186/s13023-015-0328-4
OPEN ACCESS
Twenty-nine Friedreich ataxia patients were identified in Norway, of which 23 were ethnic Norwegian, corresponding to a prevalence of 1:176 000 and 1:191 000, respectively. The highest prevalence was seen in the north. Carrier frequency of 1:196 (95 % CI = [1:752–1:112]) was found.

Pilot Study of a 3d Motion Device- Feasibility Assessment in Patients with Parkinson’s Disease and Friedreich’s Ataxia
Disease Category: Friedreich's Ataxia
Location: University of South Florida- Mosani Center for Advnaced Healthcare, Tampa, FL 33612 United States
This study includes the use of a 3D motion device that measures movement in three directions. It is being used as part of this research study to find out if it accurately tracks motion so it can be used in other ataxia research trials in the future.

EUCHROMATIC REGION TARGETING METHODS FOR MODULATING GENE EXPRESSION
United States Patent Application 20150232858, Inventors: Ozsolak, Fatih (Boston, MA, US), RaNA Therapeutics, Inc. (Cambridge, MA, US). Publication Date: 08/20/2015
According to some aspects of the invention, methods and compositions are provided herein that are useful for increasing gene expression in a targeted and specific manner. Aspects of the invention are based on the identification of euchromatic regions of genes that overlap with sequences encoding antisense RNA transcripts. It has been found that oligonucleotides that are complementary to these particular euchromatic regions of target genes are useful for increasing expression of target genes when delivered to cells. In some embodiments, oligonucleotides are provided that are complementary with these euchromatic regions and that have chemistries suitable for delivery, hybridization and stability within cells. Furthermore, in some embodiments, oligonucleotide chemistries are provided that are useful for controlling the pharmacokinetics, biodistribution, bioavailability and/or efficacy of the oligonucleotides in vivo. Accordingly, in some embodiments, oligonucleotides provided herein are useful for the treatment of diseases or conditions associated with decreased levels of target genes.....

An exploratory qualitative investigation of psychosocial determinants of parental decisions to support sport participation for youth with a mobility impairment
Celina H. Shirazipour, Amy E. Latimer-Cheung, Kelly P. Arbour-Nicitopoulos, Research in Developmental Disabilities, Volumes 45–46, October–November 2015, Pages 400-410, ISSN 0891-4222, http://dx.doi.org/10.1016/j.ridd.2015.08.001.
Compared to parents of non-athletes, parents of athletes identified different, more specific positive outcome expectations, including: being included and family networking. First, while parents of non-athletes viewed inclusion as a social benefit, half of parents of athletes stated that inclusion through sport and being part of the mainstream were important benefits in their own rights, providing distinct outcomes including a sense of normalcy. Second, half of the parents of athletes identified the family benefit of networking with other families. The family network developed within the sport organization provided opportunities to share their enjoyment of their children’s participation, discuss impairment concerns, and gain knowledge from others’ experiences.

Evidence for chromosome fragility at the frataxin locus in Friedreich ataxia
Daman Kumari, Bruce Hayward, Asako J. Nakamura, William M. Bonner, Karen Usdin,Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis, Available online 30 August 2015, ISSN 0027-5107, http://dx.doi.org/10.1016/j.mrfmmm.2015.08.007.
The region of chromosome 9 that contains the Frataxin (FXN) locus is prone to breakage and rearrangements.This chromosome fragility involves the generation of chromosome/chromatid gaps or breaks, or the high frequency loss of one or both copies of the affected gene when cells are grown under folate stress or as we showed previously, in the presence of an inhibitor of the ATM checkpoint kinase.
