Hip joint torques in type II diabetes with and without neuropathy.
Laleh Abadi, Zahra Salahzadeh, Mandana Rezaei and 2 others
PMID 30931043WHAT IT FOUND
Static hip strength did not differ among people with diabetic neuropathy, diabetes without neuropathy, and healthy controls.
When the hip moved, extension and abduction strength were lower in the neuropathy group than controls.
Key findings
01Static hip flexion, extension, abduction and adduction torque measures did not differ among the three groups.
02During moving tests, hip extension peak torque and extension peak torque normalised to body weight were lower in the neuropathy group than in the diabetes without neuropathy group and controls.
03During moving tests, hip abduction peak torque, abduction peak torque normalised to body weight and abduction average peak torque were lower in the neuropathy group than in controls.

What it does not show
The neuropathy group had only 12 participants, so small differences could have been missed. Peripheral neuropathy severity was not classified, although strength loss may relate to severity. Only the non-dominant leg was tested, so bilateral differences were not examined. Moving tests were performed only at 60 degrees per second, and eccentric hip torque was not tested. Controls were university clerks matched for age, sex and body mass index, which may limit generalisability. The study measured laboratory hip torque, not walking, balance, falls or daily function.
Declared interests
The authors declared no conflicts of interest, and the study was funded by Tabriz University of Medical Sciences.
The easy way to misread this
Do not read the lower moving hip extension and abduction strength as proof that all people with type II diabetes have hip weakness or that exercise can correct it. Static hip strength did not differ, the neuropathy group was small, and no treatment was tested.
