The power supply circuit 202 supplies operating power to the electrical signal output device 20. The low frequency output driver 203 outputs a low frequency pulse signal based on the control signal of the control circuit 210. The oscillator 206 supplies a clock signal having a predetermined frequency to the control circuit 210. The operation mode selection switch 207 is a switch for switching an operation mode (described later) in which the electric signal output device 20 outputs an electric signal. The reset circuit 208 supplies a reset signal to the control circuit 210.
　低周波出力用ドライバ２０３から出力された信号は、出力調整用メインボリューム２０９において無段階調整され、増幅回路２００に出力される。増幅回路２００は、第１増幅回路２００Ａと第２増幅回路２００Ｂとを備える。 The signal output from the low frequency output driver 203 is steplessly adjusted in the output adjustment main volume 209 and output to the amplifier circuit 200. The amplifier circuit 200 includes a first amplifier circuit 200A and a second amplifier circuit 200B.
　第１増幅回路２００Ａは、右脚用の膝電極１２Ａ及びこれに対応する第１の腰部電極１１Ａに接続される。第２増幅回路２００Ｂは、左脚用の膝電極１２Ｂ及びこれに対応する第２の腰部電極１１Ｂに接続される。第１増幅回路２００Ａ及び第２増幅回路２００Ｂは、低周波出力用ドライバ２０３から出力された信号を増幅する。 The first amplifier circuit 200A is connected to the knee electrode 12A for the right leg and the corresponding first waist electrode 11A.

The intensity of the signal output from 200B is adjusted. With this configuration, the first output adjustment sub-volume 211A and the second output adjustment sub-volume 211B are separately adjusted for the signal output from the right leg knee electrode 12A and the signal output from the left leg knee electrode 12B. By doing so, the electric current supplied to the left and right legs can be made different. That is, the user sets the adjustment amount of the first output adjustment sub-volume 211A to be larger than the adjustment amount of the second output adjustment sub-volume 211B, so that the current output from the knee electrode 12A for the right leg is set for the left leg. It can be made stronger than the current output from the knee electrode 12B.

　動作モード選択スイッチ２０７は、使用者による図略の操作部の操作により入力される指示に従って、以下に示す第１出力モード及び第２出力モードを切り換えるためのスイッチである。すなわち、動作モード選択スイッチ２０７は、使用者により入力された第１出力モード又は第２出力モードのいずれを実行するかを示す指示を制御回路２１０に出力する。制御回路２１０は、動作モード選択スイッチ２０７からの当該指示に従って、第１出力モード又は第２出力モードのいずれかの出力パターンを生成させる制御信号を低周波出力用ドライバ２０３に出力する。低周波出力用ドライバ２０３は、電源回路２０２から供給される上記ＤＣ６Ｖの電圧に基づいて、制御回路２１０からの当該制御信号の示す第１出力モード又は第２出力モードに対応した周波数及び出力タイミングからなる電気信号を生成する。なお、図４に破線で示す増幅回路及び出力調整サブボリュームは後述する変形形態で用いる構成である。 The operation mode selection switch 207 is a switch for switching between a first output mode and a second output mode described below in accordance with an instruction input by an operation of an operation unit (not shown) by a user. That is, the operation mode selection switch 207 outputs an instruction indicating whether to execute the first output mode or the second output mode input by the user to the control circuit 210. The control circuit 210 outputs a control signal for generating an output pattern of either the first output mode or the second output mode to the low frequency output driver 203 in accordance with the instruction from the operation mode selection switch 207. The low frequency output driver 203 is based on the frequency and output timing corresponding to the first output mode or the second output mode indicated by the control signal from the control circuit 210 based on the voltage of DC6V supplied from the power supply circuit 202. An electrical signal is generated. Note that the amplifier circuit and the output adjustment subvolume indicated by broken lines in FIG.

FIG. 5A is a diagram showing an output pattern in the first output mode by the electric signal output device 20, and FIG. 5B is a diagram showing an output pattern in the second output mode.
　第１出力モードの出力パターンは、図５（Ａ）に示すように、周波数が20(Hz)のパルス信号を連続的に5秒間出力した後に、2秒間出力を停止する刺激パターンを繰り返し行う。また、第２出力モードの出力パターンは、図５（Ｂ）に示すように、周波数が4(Hz)のパルス信号を連続的に出力している（つまり、出力を禁止する時間がない）。 As shown in FIG. 5 (A), the output pattern in the first output mode repeats a stimulus pattern in which output is stopped for 2 seconds after a pulse signal having a frequency of 20 (Hz) is continuously output for 5 seconds. In the output pattern of the second output mode, as shown in FIG. 5B, a pulse signal having a frequency of 4 (Hz) is continuously output (that is, there is no time for prohibiting output).

Thus, the first waist electrode 11A is positioned at a position corresponding to the right side surface of the human body waist, and the second waist electrode 11B is positioned at a position corresponding to the left side surface of the human body waist.
　(2)ステップ２において、使用者は、右脚用の膝装着部材２２Ａを右脚の膝部周りに巻き付けるとともに、面ファスナー２２１ａを面ファスナー２２２ａに押し付けて、右脚用の膝装着部材２２Ａを右脚の膝部に固定する。これにより、右脚の膝電極１２Ａは、右脚の膝部を包囲する位置に位置決めされる。さらに、使用者は、左脚用の膝装着部材２２Ｂを左脚の膝部周りに巻き付けるとともに、面ファスナー２２１ｂを面ファスナー２２２ｂに押し付けて、左脚用の膝装着部材２２Ｂを左脚の膝部に固定する。これにより、左脚の膝電極１２Ｂは、左脚の膝部を包囲する位置に位置決めされる。 (2) In step 2, the user wraps the knee mounting member 22A for the right leg around the knee portion of the right leg, and presses the hook-and-loop fastener 221a against the hook-and-loop fastener 222a, thereby moving the knee mounting member 22A for the right leg. Secure to the knee of the right leg. Thereby, the knee electrode 12A of the right leg is positioned at a position surrounding the knee portion of the right leg. Further, the user wraps the knee mounting member 22B for the left leg around the knee portion of the left leg and presses the hook-and-loop fastener 221b against the hook-and-loop fastener 222b so that the knee mounting member 22B for the left leg is moved to the knee portion of the left leg. To fix. Thereby, the knee electrode 12B of the left leg is positioned at a position surrounding the knee portion of the left leg.
　(3)ステップ３において、使用者は、電気信号出力装置２０の導電線２０１Ａを、腰部電極装着部材２１における第１の腰部電極１１Ａの接点１１０Ａ及び右脚用の膝装着部材２２Ａにおける膝電極１２Ａの接点１１０Ａ’に接続する。 (3) In step 3, the user connects the conductive wire 201A of the electrical signal output device 20 to the contact 110A of the first waist electrode 11A in the waist electrode mounting member 21 and the knee electrode 12A in the knee mounting member 22A for the right leg. To the contact 110A ′.
　(4)ステップ４において、使用者は、電気信号出力装置２０の導電線２０１Ｂを、腰部電極装着部材２１における第２の腰部電極１１Ｂの接点１１０Ｂ及び左脚用の膝装着部材２２Ｂにおける膝電極１２Ｂの接点１１０Ｂ’に接続する。 (4) In step 4, the user connects the conductive wire 201B of the electrical signal output device 20 to the contact 110B of the second waist electrode 11B in the waist electrode mounting member 21 and the knee electrode 12B in the knee mounting member 22B for the left leg. To the contact 110B ′.
　(5)ステップ５において、使用者は、電気信号出力装置２０の操作部を操作し、電気信号出力装置２０の電源をオンにすると共に、上記第１出力モード及び第２出力モードのうちいずれかの出力モードを選択して、電気信号出力装置２０を動作させる。 (5) In step 5, the user operates the operation unit of the electric signal output device 20 to turn on the electric signal output device 20, and one of the first output mode and the second output mode.

　これにより、大臀筋、大腿四頭筋、大腿二頭筋、下腹部あたりの腹直筋及び腹斜筋、長内転筋等の多くの筋肉に対して、筋繊維に沿って効率よく電気刺激を付与することができる。これにより、有効な筋運動を従来よりも効果的に誘発することができる。 As a result, many muscles, such as the greater gluteus, quadriceps, biceps, rectus abdominis, obliques, and adductor muscles, can efficiently conduct electricity along the muscle fibers. Stimulation can be applied. Thereby, effective muscle movement can be induced more effectively than before.
　さらに、従来は、有効な筋運動を誘発するために、より多くの位置に電極を配置しなければならなかったが、本実施形態では、腰部と膝部に電極を配置するだけでよいため、電極の装着作業が簡素化される。また、電極の数が減ることにより、出力調整ボリュームの数が削減されるため、操作負担を軽減することができる。すなわち、非健常者のリハビリ時の負担を軽減しながら、リハビリ活動を支援することができる。 Furthermore, in the past, in order to induce effective muscle movement, electrodes had to be arranged in more positions, but in this embodiment, it is only necessary to arrange electrodes in the waist and knees, The electrode mounting operation is simplified. Moreover, since the number of output adjustment volumes is reduced by reducing the number of electrodes, the operation burden can be reduced. That is, it is possible to support rehabilitation activities while reducing the burden of non-healthy people during rehabilitation.

It is a figure which shows the experimental result by the comparative example 1 with a bar graph for every test subject.

In addition, the difference between before and after the electrical stimulation of the lactic acid value (difference before and after the start of energization) in Example 1 is about twice that of Comparative Example 1 by two subjects of KW and YM.
　従って、比較例１として示した従来の電気刺激方式よりも、実施例１として示した電気刺激用装着具１を用いた第１出力モードによる電気刺激方式の方が、筋肥大に有効であるということがわかった。 Therefore, the electrical stimulation method in the first output mode using the electrical stimulation wearing device 1 shown as Example 1 is more effective for muscle hypertrophy than the conventional electrical stimulation method shown as Comparative Example 1.
