Management of Muscle Tone When Baclofen is Ineffective

Introduction to Alternative Therapies

The American College of Physicians recommends considering botulinum toxin injections for focal spasticity or intrathecal baclofen for generalized spasticity that has not responded to oral medications when baclofen is ineffective 1, 2

Tizanidine or dantrolene can be considered as alternative oral agents for generalized spasticity when baclofen is ineffective, with a moderate level of evidence supporting their use 1
Gabapentinoids, such as pregabalin or gabapentin, are recommended as first-line adjuvant analgesics for neuropathic pain that may accompany spasticity, based on strong evidence 1
Orphenadrine and methocarbamol have been proposed for muscle cramps in patients with cirrhosis when baclofen is ineffective, although the evidence is limited 3
Quinidine at 400 mg/day for 4 weeks has shown effectiveness against painful muscle cramps, though toxicities like diarrhea may limit its use, with a low level of evidence supporting its use 3

First-line approaches should include antispastic positioning, range of motion exercises, stretching, splinting, and serial casting, based on expert consensus 1
Physical therapy modalities, functional electrical stimulation, and transcutaneous electrical nerve stimulation may improve upper-extremity motor outcomes, with a moderate level of evidence supporting their use 1
For patients with tense ascites and muscle cramps, human albumin solution (20-40 g/week) may be considered, although the evidence is limited 3

Botulinum toxin is recommended for focal spasticity and has been shown to be more effective than baclofen for certain applications, with a high level of evidence supporting its use 1, 2
Targeted injection of botulinum toxin into localized muscles can reduce spasticity that interferes with function, based on strong evidence 2
A small RCT found botulinum toxin superior to oral baclofen for ankle spasticity, with a moderate level of evidence supporting its use 1

Intrathecal baclofen is indicated for patients with severe spastic hypertonia unresponsive to maximum doses of oral baclofen, with a high level of evidence supporting its use 1
Studies show >80% of patients have improvement in muscle tone and >65% have improvement in spasms with intrathecal baclofen, based on strong evidence 1

Avoid benzodiazepines during stroke recovery due to potential negative effects on recovery, based on expert consensus 1
Baclofen may worsen obstructive sleep apnea by promoting upper airway collapse during sleep, with a moderate level of evidence supporting this association 1, 4
Patients with chronic kidney disease generally require higher doses of loop diuretics and lower doses of aldosterone antagonists when managing muscle tone issues related to ascites, although the evidence is limited 3
