Cumulative Trauma Disorders (CTDs) is the mostcommontermusedtorefertothediseasesrelatedtotheupperlimbs.Similartermsusedtodescribetheseproblemareasare: • repetitivestraininjuries • occupationalcervicobrachialdisorders • occupationaloverusesyndromesCumulativeTraumaDisordersarecausedbyrepetitivestressesonaparticularbodypartafterperiodsofjobrelatedmicro-trauma.Basicallytherearethreetypesofinjuriestothemachineoperator.Theseinjuriesincludenerve disorders, tendon disorders or neuro-vasculardisorders.NerveDisorders-CarpalTunnelSyndrome(CTS)Common Tendon Disorders-Tendinitis, Tenosynovitis,DeQuervain's disease, Stenosing Tendsynovitas,StenosingTenosynovitasCrepitans.NeurovascularDisorders-Thoracicoutletsyndrome.
The Industrial Problem of Cumulative Trauma Disorders (CTDs) and Carpal Tunnel Syndrome (CTS)
Benefits Human Factor Engineering (Ergonomics)UltraTouch® has been designed to interact with theoperator, machine operation, and the work place in asafeandefficientway.Thiseffectivedesignofequipmentwill be most helpful in the controlling of Carpal TunnelSyndrome and other Cumulative Trauma Disorders.
Productivity IncreasesIncreases in productivity are achieved by a reductionin operator fatigue and operator injury alongwith basic production line cycle time decreases.
Employee MoraleEasier job related actions and movements with bothworkmethodsanalysisandergonomicchecklistanalysisprovideahealthierandmorepositiveworkenvironment.
Fatigue ControlEase of safe machine activation enables the machineoperators to utilize their energy for more productiveefforts.The reductionof fatigue isanessential elementwhentryingtocontrolCumulativeTraumaDisorderssuchasCarpalTunnelSyndrome.
What UltraTouch® Does For YouThe patented soundergonomic design criteriaof UltraTouch® advancesmachine cycle initiationintothe21stcentury.TheUltraTouch system hasbeen designed so themachine operator caninitiate the machine cyclewith their hand and wristareaintheneutralpositionand with no exertion offorceorpressure.This minimizes hand,wrist, and arm stressesrelated to the potentiallyharmful extension andflexion positions of thehand required to activateconventionalspring-loadedpalm buttons. No flexingof the wrist is necessarywithUltraTouch®.
Wrist and hand positionsare most important ascontributing elements ofCarpal Tunnel Syndrome.Wristposition is importantbecauseitaffectsthelengthandtensionrelationshipofcontracting muscles. Astheangleofthejoint(wrist)increases or decreasesbeyond its midpoint(neutral position), there isa proportional decreasein the machine operatorseffective strength. Thismeans thatmore exertionor tendon tension isrequired todoa taskwithabentwristthanthesametask with the wrist in theneutralposition.Handandwrist posture along withforce required are basecontributing elements toCarpalTunnelSyndrome.

Economic JustificationThere are substantial costs related to Carpal TunnelSyndromeversusthecostsandbenefitstopreventthem.Variousfactorsthatcanbeincorporatedintotheanalysisarereducedoverheadcosts,employeemorale,reductionsin non-productive time, and improved productivity.Factors involvedwithoverheadexpensemay include:medical costs, compensation costs, lost productivitydue to injuries, absenteeism, and labor turnover.
Workman's Compensation Cost ControlUltraTouch® can reduce the costs related toCumulativeTraumaDisordersinrelationtoWorkman'sCompensation Insurance claims. Both medical anddisabilitycostscanbereducedwiththecontrolofCarpalTunnelSyndrome.The actual costs of Cumulative Trauma DisordersandCarpalTunnelSyndromeareactuallyhigher thanthosecoveredbyWorkman'sCompensationInsurance.Insurancedoesnotcovermedicaltreatmentsrendereddirectly by the employer, and many employeessupplement the disability coverage provided bythe insurance carrier. Additional costs are incurredwhen expenses are paid for by the injuredworker orby comprehensive health insurance, which may beprovidedbytheemployerasafringebenefit.
Reduced MaintenanceThe solid state design of UltraTouch® assures longlife when compared to conventional spring-loadedmechanicalpalmbuttons.Theonlycomponentwithamovingpartistheindustrialgradecaptivecontactsafetyrelay,andit isratedforanexcessof10millioncyclesandiseasilyreplaceable.The UltraTouch® module is designed to be a directreplacement into existing operator run bar stationswhichisatruemaintenanceandinstallationtimesaver.
ApplicationsTheUltraTouch®systemisdesignedtoactivateelectric,pneumatic, air clutch, and hydraulic equipment suchas punch presses, press brakes, molding machines,assembly equipment, tube benders, compactingpresses, riveters, etc. Virtually any machine that iscurrentlyusingconventionalmechanicalspring-loadedpalm buttons can now utilize the sound ergonomicdesignofUltraTouch®.
The UltraTouch® systemnegates these problemsbypermitting themachineoperator to activate themachine with no forceor pressure and with theoperators hand and wristin the premier ergonomicposition of neutral, 0ºdeviation and 100% handpowerposition.UltraTouch®eliminatesthenormal pressure requiredformachineactivationwithconventionalpalmbuttonsof the median, ulnar andradial nerve at the wristandhandarea.UltraTouch® also permitsthe machine operatorto activate the machinecyclewithorwithouthandprotection devices suchassplintsandevenheavymetal fabrication workgloves.
The machine operator’sreference hand and wristpositions illustrate thedegree of wrist deviation(bending) expressed asa percentage of handpower grip as measuredin the neutral (natural)position.TheUltraTouch®systemutilizesthepremierergonomic position ofneutral, 0º deviation and100% hand power for themachineoperator.The photo shows anoperator’s hand actuatingthe UltraTouch® modulewiththecorrectergonomichandposition.
The hand is at rest withno angle or bending atthe wrist joint and thehandisatthe“thumbsup”position.Thisisthesamenatural hand and wristpositionthat ismaintainedwhen ones arms are atrest hanging at their side.There is no need to cupand curl the fingers or torollthewristtoactuatetheUltraTouch®system.This further illustrates thetotal advanced ergonomicengineering displayed bytheUltraTouch®design.
