Arms Assigned Interventions
Experimental: Handgrip exercise
Handgrip exercise - patients allocated to this intervention will carry out an eight week post operative progressive handgrip exercise training program
Other: Post operative progressive handgrip exercise
As soon as possible post operation the patient will commence an eight week progressive handgrip training intervention
Active Comparator: Treatment as usual Other: Treatment as usual
Continue routine care, with removal of exercise information given to patients(if anye.g. do not give out squeeze balls)

Detailed Description:

The arteriovenous fistula is considered to be the gold standard form of access for haemodialysis patients, however only 37% of haemodialysis patients have this form of access. A possible explanation for this could be the high fistula failure rate due to the lack of maturation. Therefore interventions aimed at enhancing fistula maturation are warranted. One such intervention could be forearm exercise, however this recommendation is not evidence based. Therefore, the purpose of this study is to investigate whether a program of post operative progressive hand grip exercise can improve fistula maturation.
