Physical applications: zelfstudie PIJNDEMPING $2: parameters


 RK
 Zie ook ppt

1. PARAMETERS SUMMARY  RK!
1) Pulsvorm:
 weinig ≠ tussen ≠pulsvormen van zelfde type elektrische stroom
 sensatie =zachter / harder
 Voor TENS & Co
- alleen mono/bifasische van belang
 MET
- belangrijk ≠zijn

2) Frequentie
 hogere frequentie
- meer prikkels
- meer stroom
- meer gevoel
- voelt zachter
 lagere
- wat agressiever
- tot ±25 Hz = meer kloppend
 keuze hangt samen met pijnverminderende mechanisme

3) Pulsbreedte:
 bredere puls
- langer durende prikkels
 meer stroom
 meer gevoel
 10 µs meer / minder = voldoende voor merkbaar ≠
- veel groter dan bij frequentie
 keuze = belangrijk bij (a)selectieve stimulatie dikke OF dikke & dunne afferenten.
- komt overeen met keuze pijnverminderend mechanisme GC / E

4) Impulsinterval:
 adaptatie voorkomen
 TENS & MET = gebruik van deze mogelijkheid.

5) Modulatie:
 frequentie &/of pulsbreedte &/of intensiteit ∆binnen vastgestelde / instelbare grenzen.
 om aanpassing te voorkomen.
 Kleine frequentievariatie (90-100 Hz) = nauwelijks opgemerkt.
 variatie van 50-100 Hz
- zeer goed past bij poortcontrole
- duidelijk voelbaar.
6) Elektroden:
