Objectives To study the association of subclinical limited joint mobility (SLJM) with micro-vascular complications of type 2 diabetes mellitus (T2DM).

Methods T2DM patients from a tertiary care diabetic centre were compared with an equal number of age- and sex-matched non-diabetic controls from the community. Flexion and extension at the MCP and PIP joints of the non-dominant hand were measured in both groups using a validated finger goniometer. SLJM was defined as 2SD below the flexion and extension at MCP in the control group. Peripheral neuropathy (PN) was assessed using a standardized and validated screening test. Nephropathy (DN) was assessed using standardized dipsticks for microalbuminuria. Retinopathy (DR) was diagnosed and scored using a direct ophthalmoscope.

Results 236 cases and controls (Mean age: 50.7±12.2 years; 53.4% males) were analysed. The prevalence of cheiroarthropathy among the cases was 23.7%. SLJM (flexion) at the MCP and PIP joints were 42.8% and 50.3%, respectively and SLJM (extension) at the MCP was 37.3%. Table 1 gives the association of SLJM with variables. In regression analysis, PN and DN were the independent risk factors for SLJM.

Conclusions Goniometry may be proposed as a non-invasive and easily reproducible test for screening micro-vascular complications of T2DM in the community.
