Use of Ultrasound Devices for Therapy
Just like such devices as ultrasonic cleaners by Hilsonic remove contamination from every corner of the object, ultrasound therapy relieves the body from its very core.
Over the years, ultrasound therapy has become a popular choice for the treatment of body pain, especially favoured in the cases of athletes and those suffering from arthritis or other forms of chronic pain that otherwise take a lot of time to heal. They are also commonly used during treatments of injuries after an accident or during rehab.
Many such devices have been developed, to combat body pain and make way for a faster path to health. In fact, many people can even use these devices at home nowadays, and with the production of portable ultrasound therapy machines things have become easier.
Does ultrasound therapy hurt?
No, ultrasound therapy doesn’t hurt and is a painless process. However, the time taken for the therapy to take effect may vary from person to person, and as such one should not become too disheartened. It is always recommended that you take the guidance and advice of a trained and experienced physician while using ultrasound devices at home, as improper handling may be harmful.
You should also avoid the usage of ultrasound devices in some cases, such as with cancer patients or with young children. Overall, it is one of the safest treatment methods out there.
Additionally, you should also not use these devices near your brain, spine, ovaries, testicles, and lungs.
How does an ultrasound device work and what are the ways it benefits our body
The device works by producing high-frequency sound waves that penetrate deep into various parts of the body including body tissues, and provides heat which helps in alleviating pain. It reaches the most delicate parts of the body – parts that hot packs and other methods of therapy are not able to reach.
So it helps to cure your pain from within the body and not just on the surface, ensuring better treatment.
- Home machines can be hand-held and have a circular probe at the tip.
- Before the ultrasound device starts, the ultrasound gel is applied and then the device is moved around the target portions of the body in gentle, circular motions.
- In addition to producing heat, these motions also result in the production of micro-vibrations, which travel all the way to the tendons, ligaments and muscles, which improves circulation and blood flow in these areas.
- With increased blood flow, more amounts of nutrients and oxygen will be able to reach the affected areas, leading to quick healing.
The dosage of the device can change by varying the frequency of the emitted sound waves. For example, a lower frequency helps in deeper penetration, and is the most useful in the case of healing tissues.
You should adhere to the time limit for which the therapy is permitted. Going on for a longer duration may result is overheating and damage. However, as long as you follow the instruction manual carefully and take the help of someone trained and experienced in the handling of ultrasound devices, you having nothing to fear.Read more
How to setup VPN on Linux
The process steps
PPTP configuration on Linux has following basic steps which should be followed for the results. These are:
- Server setup
These steps are explained as under:
There are several coding steps included in server configuration using PPTP as a tool. These steps are easy to execute and can also be found on several other forums or websites. These are:
- Installation of PPTP server package. The related command is “sudo aptitude install pptpd”
- Editing of the configuration file is then required with code “sudo vim /etc/pptpd.conf”
- Following commands are then to be added to this file
3.1 localip 192.168.1.5
3.2 remoteip 192.168.1.234-238,192.168.1.245
- Editing of second configuraiton file “sudo vim /etc/ppp/pptpd-options”
- Appending of following commands:
- CHAP secret file editing “sudo vim /etc/ppp/chap-secrets”
- Addition of username and password for authentication “username <TAB> * <TAB> users-password <TAB> *”
- Restart connection for settings to take effect “sudo /etc/init.d/pptpd restart”
It includes following steps. Forwarding ensures that entire network is accessed by the remote users rather than VPN server only:
- Edit the file “sudo vim /etc/sysctl.conf”
- Change NetIPV4 parameter “net.ipv4.ip_forward=1”
- Execution of the command for the process to take effect “sudo sysctl -p”. Alternatively the server can also be restarted for changes
Following are some in regard to VPN connection on Linux:
- Forwarding should never be deemed or considered as network security issue
- The steps are generalized so several servers can be configured using same above steps
- Split tunnel mode should be used to set up VPN on Linux
Split tunnel connections on Ubuntu
The steps that are to be followed are mentioned as under:
- Find system> preferences > network connections > configure VPN
- On the connections interface click VPN > ADD
- Click create on next window
- After filling in all the required details click advanced
- Check MPPA, Allow stateful encryption. Press OK
- On main connections window click IPV4 settings on the top
- Check “Use this connection only for resources on its network” option and click OK
- Find system> preferences > network connections > VPN name to get started. It also finishes the process in full.
