Definitions
- the invention relates to a system incorporating telecommunication capability to assist with rehabilitation involving an instrumented orthosis.
- Suitable stress can be applied to the tissue by the performance of selected exercises.
- isometric .exercises generally involve the exertion of force against a relatively immovable object.
- a restraining device can be used that has a substantially unchanging position for the duration of a particular exercise routine.
- Isotonic exercises involve exertion against the same weight or resistance through a range of motion.
- Isokinetic exercise is designed to mimic exertions that take place on a playing field or the like.
- a machine is used to provide resistance in direct proportion to the exertion of the exerciser.
- Isometric exercises are particularly useful with painful injuries to lower the risk of further injury. If performed in a controlled manner, isometric exercises can be performed earlier in the recuperation period to speed recovery. As the patient's recovery progresses, isotonic exercises or other exercises can be used to reestablish a desired range of motion about a joint. As recovery progresses eventually the patient is able to perform a full range of exercises. A difficulty with the application of stress to an injured joint is that the application of excessive stress can further injure the joint rather than assist with the healing. Thus, the exercises need to be carefully planned to provide appropriate amounts of stress. Also, the performance of the exercises should be monitored closely by a physician, physical therapist or other appropriate health care professional to reduce the risk of injury. The need to carefully plan and closely monitor the exercises provides a cost and motivation barrier to accessing desirable amounts of rehabilitation exercise.
- Instrumented braces provide for the performance of exercises with immediate feedback. The feedback can prevent the patient from applying injurious forces and can prompt the patient to begin exercising. Instrumented braces can also have the capability of storing the patient's exercise performance parameters for later downloading to a health care professional for evaluation.
- the invention pertains to an article comprising an instrumented orthosis and a telecommunication station, wherein the instrumented orthosis is connected to the telecommunication station for the transfer of information, and wherein the telecommunication station by way of a network transmits performance values from the instrumented orthosis while exchanging oral communications during a telecommunication session.
- the invention pertains to a method of rehabilitating an injured joint, the method comprising exchanging transmissions over a telecommunication channel, the transmissions including real-time communications between a patient and a health care professional and values from an instrumented orthosis interfaced with a telecommunication station.
- the invention pertains to a method of adapting an instrumented orthosis for real time, remote evaluation by a health care professional, the method comprising interfacing the instrumented orthosis with a telecommunication station.
- the invention pertains to a method of evaluating output from an instrumented orthosis, the method comprising producing a computer database including data from the performance of a plurality of patients using a comparable instrumented orthosis .
- the invention pertains to a method of evaluating treatment with an instrumented orthosis, the method comprising exchanging communications between the patient and a health care professional by way of a video teleconference over a computer network.

- the web site can provide a variety of other functions including facilitation of data transfer without patient or health care professional coordination. Also, the web site can provide for maintenance and access to a patient data base.
- Communication signals and signals related to transducer response can be transmitted from the patient to a health care professional. Similarly, communications from the health care professional are transmitted back to the patient. Real-time communications take place between individuals such that they have a personal/live exchange while they are participating in a single session.
- the instrumented orthosis can be interfaced directly with the telecommunication device such that the digitized output related to the transducer values can be sent along with the communication signals.

- instrumented orthosis 150 includes a plurality of support portions 152 connected by a hinge 154.
- Suitable structures of hinge 154 may depend on the structure of the corresponding support structures .
- a suitable hinge 154 can include two or more hinge units 156 connecting different frame members that rotate together around a joint, as shown in Fig. 3.
- hinge 154 has a single hinge unit that meets frame members at the joint.
- support portions 152 can be connected with an articulating hinge.
- An articulating hinge can be made with resilient collapsible materials analogous to a bendable straw, sliding sections that can slide past each other to articulate, or other similar constructions. Sliding sections can be locked relative to one another by way of clamps attached to slots defining a range of motion, where the clamps are tightened manually with wing nuts or the like , or electronically with solenoids or the like.

- Angle sensors 164 can be based on one or more different measurement approaches, such as angularly dependent variable resisters, digital optical transducers, hall effect magnetometers or simple switches with angle dependent contacts, to provide an angle dependent measurable parameter. Strain gauges 160 and angle sensors 164 are described further in application 60/098,779.
- Energy propagating transducers can transmit ultrasound radiation and/or electromagnetic radiation for therapeutic purposes. It is known that propagating radiation of selected frequencies helps to speed healing of certain injuries. Energy propagating transducers used in instrumented orthoses and combinations of various transducers are described further in published PCT application WO 96/36278, entitled "An Orthopedic Device Supporting Two or More Treatment Systems and
- Continuous passive motion (CPM) devices provide for range-of-motion exercises using a motor 170.
- the exercises are passive in the sense that the patient's joint is moved without the need for applied forces by the patient.
- the orthosis controller can operate a CPM device or the like to flex a patient's joint and/or receive input from the CPM device regarding the parameters of the passive motion activity.

- CPM devices are described further in, for example, U.S. Patent 5,239,987 to Kaiser et al .
- the orthosis When forces are applied by the patient against the orthosis during exertion/exercise, the orthosis tends to change position relative to the patient's joint. This shifting reduces the effectiveness of exercises being performed with the orthosis and may necessitate realignment of the orthosis for proper fit.
- the orthosis can be designed to reduce or eliminate this shifting.
- a first approach to prevent a knee orthosis from slipping during exercise is to construct the orthosis with indentations in the femur supracondylar area just above the knee.
- An alternative solution involves the use of additional securing cuffs.
- Securing cuffs are designed to be tightened more during exercise routines to help secure the orthosis relative to the joint.
- Securing cuffs include a gripping element and, for example, can be placed against the leg above the knee such that when tightened, the gripping element applies pressure above the kneecap and pushes on the knee without pushing on the vasculature and lymphatic drainage posteriorly.
- the securing cuffs can be appropriately placed.
- Cuffs can be tightened with a variety of fasteners including hook and loop fasteners .
- Another approach to securing the orthosis involves securing the orthosis to a belt by way of one or more straps. Still another approach involves reducing the friction of the surface contacting the orthosis or part of the orthosis, for example, using a high friction, polymer sleeve. Still another approach to securing the orthosis involves the placement of crossed straps behind the joint. The straps apply forces that tend to maintain the straps in the fold of the joint. Furthermore, for a knee orthosis, the orthosis can end with a heal cup with a strap or the like around the foot to hold the bottom of the orthosis around the heal of the foot and to fix the hinge at the knee .

- Controller/server 306 can also provide access to software for either the telecommunication stations and/or an orthosis controller. For example, software upgrades based either on revisions of the software or modification indicated by treatment results can be directly downloaded over the network to the telecommunication stations. Similarly, software for orthosis controller 338 can be downloaded directly from controller/server 306 under the direction of the health care professional . The downloading of software to orthosis controller 338 can be performed as part of a telecommunication session or during a separate visit by the patient to the controller/server based on previous instructions from the health care professional.
- telecommunication capability enables the health professional to walk through the procedure again from a remote location to reassure the patient. This reassurance can improve patient compliance while reducing patient stress. Also, patient questions can be answered at an early time in the treatment program, such that the treatments are properly performed, without burdening the health professional.
- a telecommunication session provides for very efficient remote evaluation of the problem at a without requiring the patient to travel to the professional's office. Thus, scheduling difficulties can be reduced significantly.
- transducer data can be sent at roughly the same time as communications between the patient and the health care professional
- the data from the orthosis can be sent prior to the start of a telecommunications session between the patient and the health care professional, if desired.
- the health care professional can review the orthosis data prior to the telecommunication session, preferably a teleconferencing session at an internet web page or the like.
- a typical telecommunication session is outlined with a flow diagram in Fig. 8.
- the patient and health professional log-on 400 the web site. Based on user names, passwords or other information entered, the patient and health professional are connected 402 in a chat room. Through the chat room window, the patient and health professional exchange 404 personal communications and data regarding the performance of the treatment program. Generally, the health care professional opens another window to display the data from the instrumented orthosis, although other approaches are discussed above. Based on the personal communications and an examination of the orthosis data, the health professional evaluates 406 the patient performance .
- the health care professional can select 408 to access a patient database. If the professional decides to access the database, they open 410 another window for database access. The desired information is accessed 412 from the database. Whether the database is accessed or not, the health professional decides 414 whether or not the treatment program should be modified.
- the modified treatment program is designed 416. Then, the modified treatment program is downloaded 418 to the orthosis controller 338.
- orthosis controller 338 is responsive to remote programming.
- the reprogramming can be performed during the telecommunication session. If desired, the reprogrammed treatment program itself can be evaluated during the telecommunication session shortly after the reprogramming is performed.
- the health professional verifies 420 the patient's expectations regarding compliance and their satisfaction 420.
- the patent and health professional log-off 422 of the chat room and log-off 424 of the network.
