1. A soft-tissue-injury diagnostic system for diagnosing soft tissue injury within a patient, the soft-tissue-injury diagnostic system comprising:
a set of hand-held inclinometers comprising a main unit and an auxiliary unit, the inclinometers configured and arranged for placement in proximity to two ends of a patient body portion that moves along a patient joint at one end of the body portion such that the main unit is positioned in proximity to the joint and the auxiliary unit is positioned along the patient body portion that moves along a patient joint, the inclinometers configured and arranged for measuring and recording angles formed between the main unit and the auxiliary unit during controlled patient movements of the joint, wherein the controlled patient movements of the joint comprise moving the joint between a first joint position and a second joint position that is different from the first joint position, wherein at least one controller is disposed on at least one of the main unit or the auxiliary unit, and wherein the at least one controller is configured and arranged for marking the recording of the measured angles at one or more of the first joint position and the second joint position when the at least one controller is actuated by a user, wherein a plurality of spaced-apart light-emitting diodes are disposed along each of the main unit and the auxiliary unit, and wherein the plurality of light-emitting diodes indicate degree markings and are configured and arranged to enable the user to view the measured angles between the main unit and the auxiliary unit during the controlled patient movements of the joint;
a static surface electromyograph (“sEMG”) scanner, including:
at least one set of measuring electrodes that are electrically coupled to the static-sEMG scanner, the measuring electrodes configured in a housing and arranged for coupling to an exterior portion of the patient in lateral proximity to a plurality of levels of the patient's spine along the body portion that moves along the joint, the at least one set of measuring electrodes configured and for measuring action potentials along patient muscle groups beneath the measuring electrodes and transmitting the measured action potentials to the static sEMG scanner, and wherein the at least one set of measuring electrodes is non-retractable in the housing;
at least one ground electrode that is configured in the housing and arranged for placement against patient skin adjacent to the at least one set of measuring electrodes, wherein the at least one ground electrode is retractable in the housing independently of the at least one set of measuring electrodes to facilitate maintaining placement of the at least one ground electrode against patient skin during operation of the static sEMG scanner, wherein the at least one ground electrode is retractable to improve simultaneous contact with the patient skin between the static sEMG scanner and the at least one set of measuring electrodes, and wherein the at least one ground electrode is configured in an extended position beyond a surface of the housing and a position of the at least one set of measuring electrodes until the at least one ground electrode retracts from the extended position to a compressed position that is closer to the surface of the housing when the at least one set of measuring electrodes and the at least one ground electrode are placed against the patient skin; and
a hub configured and arranged for receiving the data collected from the inclinometers and the static sEMG scanner during the controlled patient movements of the joint and processing the received data into at least one displayable image; and
a visual display electrically coupled to the hub, the visual display configured and arranged for receiving and displaying the processed data from the hub.
