The pharmacological options for tremor are limited and frequently produce side effects that reduce quality of life. Non-pharmacological approaches through physiotherapy and occupational therapy often go underutilised, partly because referral rates are lower than they should be and partly because patients and clinicians underestimate their potential. The evidence base has grown substantially over the past decade.
Occupational Therapy: Function Over Symptom Suppression
Occupational therapy for tremor focuses on enabling the individual to perform daily tasks with less interference from the tremor, rather than reducing the tremor itself. The approach includes task analysis, environmental modification, and training in compensatory strategies. A 2015 Cochrane review of occupational therapy in Parkinson's disease found evidence for significant improvements in performance of activities of daily living and patient-reported quality of life.
Weighted Adaptive Equipment
Adding wrist weights or using weighted utensils and writing aids can reduce the functional impact of tremor by increasing joint inertia. A systematic review in the American Journal of Occupational Therapy (2015) found consistent benefits across studies using wrist weights of 0.5 to 2kg for essential tremor. The optimal weight varies by individual and by the specific task; OT assessment allows titration. Weighted gloves and cutlery are commercially available and widely effective.
Technology-Based Interventions
Tremor-cancelling technology has advanced substantially. The Gyenno DETA spoon (tremor-compensating eating utensil) uses electronic stabilisation to compensate for hand tremor in real time. Liftware (now discontinued but alternatives exist) demonstrated significant functional benefit in clinical trials. For writing, thicker pen handles and finger guides reduce tremor interference. Keyboard and voice control technology increasingly reduces the dependence on fine motor tasks for communication.
Physiotherapy: Balance, Posture, and Gait
For Parkinson's tremor specifically, physiotherapy focuses on balance rehabilitation, fall prevention, and maintaining gait quality. The LSVT BIG programme (Lee Silverman Voice Treatment extended to movement) is the most evidence-supported physiotherapy protocol in Parkinson's disease, improving amplitude of movement and reducing motor hesitancy. For essential tremor, proprioceptive training and core stability work improve postural control that reduces the functional consequences of limb tremor.
