Pain measures in AIM compared with other neuromuscular or rheumatic diseases
| Study | AIM subsets | Pain severity* | Findings | |
| AIM | Disease comparators | |||
| SF-36 BP (additive 0–100, norm-based mean 50, SD 10); lower score, more pain | ||||
| Sadjadi et al29 | IBM | Mean±SD 69±27 | Mean±SD FSHD: 67±24 MyoDys: 75±25 CMT 1: 69±26 Various NMDs: 63±26 | Comparable burden of pain with IBM and other NMDs |
| Goreshi et al23 | DM | Norm-based Mean: 50 | Norm-based Mean: SLE: 43 CLE: 54 | |
| Feldon et al22 | DM, PM, IBM, adult JDM | Norm-based Mean±SE 43±0.28 | Norm-based Mean±SE RA: 42±0.85 | Comparable burden of pain with RA |
| NHP score (0–100); higher score, more pain | ||||
| Chung et al19 | DM, PM | Mean±SD 30±32 | Mean±SD RA: 49±34 OP: 33±36 OA: 41±27 | Less pain in AIM compared with RA and OA (p<0.002) |
| INQOL score; higher score, more pain | ||||
| Rose et al33 | DM, PM, IBM | Mean±SD PM/DM: 70±20 IBM: 46±29 | Mean±SD LGMD: 45±26 FSHD: 40±23 MyoDys: 41±27 Various NMDs: 35±23 | More pain in DM/PM compared with NMD |
