Mixed EMG motor unit potentials may support inclusion body myositis suspicion in select cases; leaves open prospective validation of diagnostic criteria.

What are the electrophysiological features of inclusion body myositis?
Inclusion body myositis demonstrates a heterogeneous EMG profile, with a mixed pattern of large and small MUPs being highly suggestive but present in only about one third of cases.
Joy et al. (1990) conducted an observational in Inclusion body myositis (n=30). Electromyography and nerve conduction studies was evaluated on Electrophysiological features. Electromyography in inclusion body myositis demonstrated a heterogeneous profile, with a mixed pattern of large and small motor unit potentials seen in 36.7% of patients.
