Compare the Richmar TheraTouch CX2, CX4, and EX4 clinical therapy systems by channel count, ultrasound, and cart options so you can choose the right configuration for your practice.
Quick answer
Choose the TheraTouch CX2 if you need a compact two-channel electrotherapy and ultrasound unit for a single treatment room. Step up to the CX4 when you routinely treat two patients at once or need four-channel coverage, and choose the EX4 when you want the same four-channel platform with a mobile cart for shared or multi-room use.
Why channel count changes your daily workflow
The biggest practical difference between the CX2 and the CX4 is how many patients or body areas you can treat simultaneously. A two-channel unit covers one treatment setup at a time, which suits a single clinician working in one room. A four-channel unit lets you run two separate circuits, so you can treat two patients or two regions without waiting for one session to finish.
That matters most in busy clinics where treatment bays are shared and turnover is tight. If your schedule rarely overlaps sessions, the extra channels add cost without adding much throughput.
Ultrasound and combination therapy across the family
All three model lines include therapeutic ultrasound and combination therapy, so the choice is not about whether you get ultrasound. Instead, compare how you will use ultrasound alongside electrotherapy. Combination therapy lets you apply both modalities in one session, which can save setup time when a plan of care calls for both.
If your caseload is mostly electrotherapy with occasional ultrasound, a two-channel configuration may be enough. If ultrasound is a routine part of most visits, the larger platform gives you more scheduling flexibility.
Cart or no cart: the EX4 decision
The EX4 adds a mobile therapy-cart configuration, which matters if equipment must move between treatment rooms, beds, or departments. A cart-based system keeps the unit, accessories, and supplies together and reduces the need to duplicate devices across rooms.
If your device stays in one dedicated space, a cart may be unnecessary bulk and expense. Decide based on how often the unit actually needs to move, not on how often it might.
Where the CX2 and CX4 can fall short
The CX2 and CX4 are not cart-based configurations, so they suit fixed treatment rooms rather than roaming use. The CX2 also limits you to two channels, which can become a bottleneck if your schedule regularly overlaps sessions.
None of these systems is a portable home unit, and the catalog does not list lightweight or battery-powered operation. If you need a device for home visits or a small satellite space, look at a different class of equipment.
Decision rules for choosing your TheraTouch configuration
- Rule 1: Count simultaneous treatment setups: If you never run two treatment setups at once, choose a two-channel CX2 configuration. If you regularly treat two patients or two regions in parallel, choose a four-channel CX4 or EX4. Write down your busiest hour and count how many setups overlap before you decide.
- Rule 2: Decide whether the unit must move: If the device stays in one room, a CX2 or CX4 without a cart is the simpler choice. If it must travel between rooms or beds, choose the EX4 mobile cart configuration. Measure doorways and storage space if you plan a cart.
- Rule 3: Match ultrasound use to the platform: If ultrasound is occasional, a two-channel CX2 keeps the footprint and cost lower. If ultrasound and combination therapy are routine, the four-channel CX4 or EX4 gives more scheduling room. Review a typical week of plans of care to see how often ultrasound appears.
- Rule 4: Plan for growth, not hypotheticals: Buy for the patient volume and room layout you expect in the next year. Upgrading later costs more than choosing the right channel count now, but paying for unused channels ties up budget. If your volume is uncertain, start with the CX2 and revisit when overlapping sessions become routine.
