 CONFLICTS OF INTEREST The Principle or Chief Investigators will be involved in clinical evaluation of CTS patients at their appointment. Special care will be taken to ensure patients are aware that study participation does not affect their normal care in any way. Care will be taken to avoid any form of coercion. The Principle or Chief Investigators may also perform surgical treatment on appropriate patients, however this is separate to the study and should not affect care in any way. Effort will be made to ensure patients are not coerced into returning for follow-up grip testing after their operation. Patients may wish to attend extra follow-up appointments. At the end of the study, patients are discharged back to the care of their GP, to be referred back if any concerns arise as is normal practice. Participants will be aware that they will not know the results of their grip tests, but the intent will be to publish a full paper within twelve months.
