This m ight be explained b y vir­ tue o f the fact that there is reflex spasm o f the rhom boid and erector spinae muscles. R otation o f the thorax tow ards the painful side involves scapular retraction on that side, recruiting the affected m uscles and eliciting pain. Im plications for treatm ent M obilisation o f the cervical spine by direct pressure produced positive results.

The patient responded rapidly to interm it­ tent variable cervical traction and it w ould be interesting to assess the value o f this m odality in other cases o f this nature. REFERENCES 1.

PHYSIOTHERAPY ON THE INTERNE by Larry Ian Cohen Introduction T h e n u m b e r o f c o m p u t e r u s e r s throughout the w orld is increasing rap­ idly, as are the nu m ber o f fu nctions that the com puters are able to perform . The linking o f com puters is term ed netw ork­ ing and can involve a local area netw ork (LAN), a larger m etropolitan area netw ork (M A N ) and even a w id e area netw ork (W A N ). W hen com p u ters are netw orked users can "ta lk " to others, send m essages and share files and program s, and is the principle o f the Internet, a global internet­ w orking o f com puter system s. The exact nu m ber o f users on the In ­ ternet is increasing exponentially b u t cu r­ rent estim ates place usage at 34,000 n et­ w orks, 5 m illion com puters and 20 m illion u sers1. The m ain key feature o f the Internet is that it allow s heterogeneous com puters to com m unicate w ith each other using a "co m m o n langu ag e", transm ission control p r o to c o l/ In te r n e t p ro to c o l (T C P / IP )2. This allow s A pple com puters, IBM m a­ chines, v ario u s m ainfram es and super­ com puters to com m unicate w ith one an­ other. Electronic mail (e-m ail) The m ost basic use o f the Internet in­ volv es electronic m ail (e-m ail) w hereby user x at com puter a is able to send a m essage to user y at com puter b. C om ­ puter b could b e in the room n ext d oor or halfw ay across the w orld, and the time it takes for m essages to travel across the net­ w ork can be m easured in seconds. Like ordinary m ail (snail m ail), e-m ail requires an Internet address so that it can reach its d estination. Internet addresses follow a logical pattern : person@ m achine.sitenam e.sitetype.coun try (eg: 0571arry@ w itsvm a.w its.ac.za) where: • person is the userid of the person on the netw ork eg. 0571arry • m achine is the com puter's nam e on the internet eg. w itsvm a • sitenam e is the nam e o f the institution eg. wits • sitetype is the type o f institu tion eg ac (academ ic) • cou ntry eg. za (South A frica) M ailing lists are a slight variation on e-m ail. T hey allow users w ith sim ilar inter­ ests to subscribe to a list. M ail is forw arded to all thfe m em bers o f the list w ho can then decide w heth er to act, store, o r discard the message. Y ou m ay be w ond ering w h at this h as to do w ith p h y sio th e ra p y , w e ll the good new s is that physiotherapists now have their ow n m ailing list (PH Y SIO ) w h ich is based in the UK. P H Y SIO aim s to provide a global forum fo r everybody interested in p h y s io th e ra p y , n a m e ly u n d e rg ra d u a te students, researchers, edu cators, clinicians and adm inistrators. How to subscribe to PHYSIO: You need a com p u ter that is connected to the Internet, via a direct link or via a m odem . T h e re are co m m ercial b u lle tin b oard s in Sou th A frica that act as gatew ays onto the Internet. M em bers o f the public can subscribe to the b u lletin b o ard s for a nom inal annual fee. O nce you are ab le to connect to the Internet and have a personal Internet address, send a m essage to: m ailbase@ m ailbase.ac.u k w ith the fo llow ing instruction in the bod y o f the m essage: • jo in physio firstnam e lastnam e (eg. jo in p hysio Jo h n D oe) T h e m a ilb a s e s y s te m a u to m a tic a lly R ep ro du ce d by S ab in et G at ew ay u nd er li ce nc e gr an te d by th e P ub lis he r (d at ed 2 01 3. ) mailto:0571arry@witsvma.wits.ac.za mailto:mailbase@mailbase.ac.uk adds y ou r nam e to the PH YSIO list and sends you back instructions o n how to use the system . To send m essages to the m em ­ b ers o f PH YSIO , send to P H Y SIO (the list - n ot m ailbase) at the address: physio@ m ailbase.ac.uk Not only does PH YSIO act as a tool to com m unicate w ith other physiotherapists, PH YSIO also acts as a d ocu m ent server. D ocum ents related to physiotherapy (eg. Q u een M a rg a re t C o lle g e 's B Sc P h y sio­ therapy cou rse d ocum ent) are kept in the m a ilb a s e s y s te m , a n d a r e r e tr ie v a b le through PH YSIO . All this is covered in the Instru ctions tha t are sen t after adding your nam e to PH YSIO . T here are also countless other m ailing lists to subscribe to, such as vegetarian food recipes, running, astron­ om y, jo kes - the list is endless. Other applications of the Internet T he Internet carries a vast num ber o f inform ation d atabases and p ro gram s that can be accessed on-line or retrieved to read or run on your ow n com puter. There are tools to assist you in finding the inform a­ tion (and location) you are interested in4. Instruction in the use o f these tools extends beyond the scope o f this article but the follow ing is a short introd u ction to the op tions available. T he first is a program called A RC H IE w hich is able to search through files indexed on the Internet using keyw ords supplied by you. O nce a file is found it can be transferred to your com ­ p u ter u sin g the file tran sfer proced u re (FTP). The process of telnetting or rem otely logging onto a distant com puter allow s you to gain access to num erous types of d atabases, including libraries and other public or governm ent services throughout the w o rld . O th e r s y s te m s to a s s is t in searching for inform ation are the gopher, w ide area inform ation server (W AIS) and the w orld w ide w eb (W W W ). These m ethods allow you to read the infor­ m ation on-line (at the d ocu­ m ents source) through a se­ ries o f easy -to -u se m en u 's. This saves you from having to transfer the inform ation to you r com p u ter in order to read it. This article has hopefully show n you som e m ore appli­ cations for com puters. South Africa has been isolated for so long, its ab ou t time w e p hysiotherapists joined o u r colleagu es in the global village. References 1. Nicoll LH.
